Interface PreparedStatement

  • All Superinterfaces:
    AutoCloseable, Statement, Wrapper
    All Known Subinterfaces:
    CallableStatement


    public interface PreparedStatement
    extends Statement
    An object that represents a precompiled SQL statement.

    A SQL statement is precompiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

    Note: The setter methods (setShort, setString, and so on) for setting IN parameter values must specify types that are compatible with the defined SQL type of the input parameter. For instance, if the IN parameter has SQL type INTEGER, then the method setInt should be used.

    If arbitrary parameter type conversions are required, the method setObject should be used with a target SQL type.

    In the following example of setting a parameter, con represents an active connection:

       PreparedStatement pstmt = con.prepareStatement("UPDATE EMPLOYEES
                                         SET SALARY = ? WHERE ID = ?");
       pstmt.setBigDecimal(1, 153833.00)
       pstmt.setInt(2, 110592)

        ResultSet executeQuery()
                        throws SQLException
        Executes the SQL query in this PreparedStatement object and returns the ResultSet object generated by the query.
        Returns:
        a ResultSet object that contains the data produced by the query; never null
        Throws:
        SQLException - if a database access error occurs; this method is called on a closed PreparedStatement or the SQL statement does not return a ResultSet object
        SQLTimeoutException - when the driver has determined that the timeout value that was specified by the setQueryTimeout method has been exceeded and has at least attempted to cancel the currently running Statement
      • executeUpdate

        int executeUpdate()
                   throws SQLException
        Executes the SQL statement in this PreparedStatement object, which must be an SQL Data Manipulation Language (DML) statement, such as INSERT, UPDATE or DELETE; or an SQL statement that returns nothing, such as a DDL statement.
        Returns:
        either (1) the row count for SQL Data Manipulation Language (DML) statements or (2) 0 for SQL statements that return nothing
        Throws:
        SQLException - if a database access error occurs; this method is called on a closed PreparedStatement or the SQL statement returns a ResultSet object

                            int length)
                     throws SQLException
        Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format.

        Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

        Parameters:
        parameterIndex - the first parameter is 1, the second is 2, ...
        x - the Java input stream that contains the ASCII parameter value
        length - the number of bytes in the stream

        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
      • setUnicodeStream

        @Deprecated
        void setUnicodeStream(int parameterIndex,
                                          InputStream x,
                                          int length)
                                   throws SQLException
        Deprecated. Use setCharacterStream
        Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large Unicode value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from Unicode to the database char format. The byte format of the Unicode stream must be a Java UTF-8, as defined in the Java Virtual Machine Specification.

        Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

        Parameters:
        parameterIndex - the first parameter is 1, the second is 2, ...
        x - a java.io.InputStream object that contains the Unicode parameter value
        length - the number of bytes in the stream
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method
      • setBinaryStream

        void setBinaryStream(int parameterIndex,
                             InputStream x,
                             int length)
                      throws SQLException
        Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large binary value is input to a LONGVARBINARY parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached.

        Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

        Parameters:
        parameterIndex - the first parameter is 1, the second is 2, ...
        x - the java input stream which contains the binary parameter value
        length - the number of bytes in the stream
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
      • clearParameters

        void clearParameters()
                      throws SQLException
        Clears the current parameter values immediately.

        In general, parameter values remain in force for repeated use of a statement. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling the method clearParameters.

        Throws:
        SQLException - if a database access error occurs or this method is called on a closed PreparedStatement
      • setObject

        void setObject(int parameterIndex,
                       Object x,
                       int targetSqlType)
                throws SQLException
        Sets the value of the designated parameter with the given object. This method is similar to setObject(int parameterIndex, Object x, int targetSqlType, int scaleOrLength), except that it assumes a scale of zero.
        Parameters:
        parameterIndex - the first parameter is 1, the second is 2, ...
        x - the object containing the input parameter value
        targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
        SQLFeatureNotSupportedException - if the JDBC driver does not support the specified targetSqlType
        See Also:
        Types
      • setObject

        void setObject(int parameterIndex,
                       Object x)
                throws SQLException

        Sets the value of the designated parameter using the given object.

        The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.

        Note that this method may be used to pass datatabase- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, RowId, SQLXML or Array, the driver should pass it to the database as a value of the corresponding SQL type.

        Note: Not all databases allow for a non-typed Null to be sent to the backend. For maximum portability, the setNull or the setObject(int parameterIndex, Object x, int sqlType) method should be used instead of setObject(int parameterIndex, Object x).

        Note: This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

        Parameters:
        parameterIndex - the first parameter is 1, the second is 2, ...
        x - the object containing the input parameter value
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or the type of the given object is ambiguous
      • execute

        boolean execute()
                 throws SQLException
        Executes the SQL statement in this PreparedStatement object, which may be any kind of SQL statement. Some prepared statements return multiple results; the execute method handles these complex statements as well as the simpler form of statements handled by the methods executeQuery and executeUpdate.

        The execute method returns a boolean to indicate the form of the first result. You must call either the method getResultSet or getUpdateCount to retrieve the result; you must call getMoreResults to move to any subsequent result(s).

        Returns:
        true if the first result is a ResultSet object; false if the first result is an update count or there is no result
        Throws:
        SQLException - if a database access error occurs; this method is called on a closed PreparedStatement or an argument is supplied to this method
        SQLTimeoutException - when the driver has determined that the timeout value that was specified by the setQueryTimeout method has been exceeded and has at least attempted to cancel the currently running Statement
        See Also:
        Statement.execute(java.lang.String), Statement.getResultSet(), Statement.getUpdateCount(), Statement.getMoreResults()
      • setCharacterStream

        void setCharacterStream(int parameterIndex,

                                int length)
                         throws SQLException
        Sets the designated parameter to the given Reader object, which is the given number of characters long. When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.Reader object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char format.

        Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

        Parameters:
        parameterIndex - the first parameter is 1, the second is 2, ...
        reader - the java.io.Reader object that contains the Unicode data
        length - the number of characters in the stream

              throws SQLException
        Sets the designated parameter to the given java.sql.Blob object. The driver converts this to an SQL BLOB value when it sends it to the database.

        Retrieves a ResultSetMetaData object that contains information about the columns of the ResultSet object that will be returned when this PreparedStatement object is executed.

        Because a PreparedStatement object is precompiled, it is possible to know about the ResultSet object that it will return without having to execute it. Consequently, it is possible to invoke the method getMetaData on a PreparedStatement object rather than waiting to execute it and then invoking the ResultSet.getMetaData method on the ResultSet object that is returned.

        NOTE: Using this method may be expensive for some drivers due to the lack of underlying DBMS support.

        Returns:
        the description of a ResultSet object's columns or null if the driver cannot return a ResultSetMetaData object
        Throws:
        SQLException - if a database access error occurs or this method is called on a closed PreparedStatement
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method

                     Calendar cal)
              throws SQLException
        Sets the designated parameter to the given java.sql.Date value, using the given Calendar object. The driver uses the Calendar object to construct an SQL DATE value, which the driver then sends to the database. With a Calendar object, the driver can calculate the date taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
        Parameters:
        parameterIndex - the first parameter is 1, the second is 2, ...
        x - the parameter value
        cal - the Calendar object the driver will use to construct the date

              throws SQLException
        Sets the designated parameter to the given java.sql.Time value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIME value, which the driver then sends to the database. With a Calendar object, the driver can calculate the time taking into account a custom timezone.

                   throws SQLException
        Sets the designated parameter to the given java.sql.Timestamp value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIMESTAMP value, which the driver then sends to the database. With a Calendar object, the driver can calculate the timestamp taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

                     String typeName)
              throws SQLException
        Sets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

        Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.

        Parameters:
        parameterIndex - the first parameter is 1, the second is 2, ...
        sqlType - a value from java.sql.Types
        typeName - the fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or REF
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
        SQLFeatureNotSupportedException - if sqlType is a ARRAY, BLOB, CLOB, DATALINK, JAVA_OBJECT, NCHAR, NCLOB, NVARCHAR, LONGNVARCHAR, REF, ROWID, SQLXML or STRUCT data type and the JDBC driver does not support this data type or if the JDBC driver does not support this method

              throws SQLException
        Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a CLOB.

        Parameters:
        parameterIndex - index of the first parameter is 1, the second is 2, ...
        reader - An object that contains the data to set the parameter value to.
        length - the number of characters in the parameter data.

              throws SQLException
        Sets the designated parameter to a InputStream object. The inputstream must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setBinaryStream (int, InputStream, int) method because it informs the driver that the parameter value should be sent to the server as a BLOB.

                throws SQLException

        Sets the value of the designated parameter with the given object. If the second argument is an InputStream then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a SQLException when the prepared statement is executed.

        The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

        Note that this method may be used to pass database-specific abstract data types.

        Parameters:
        parameterIndex - the first parameter is 1, the second is 2, ...
        x - the object containing the input parameter value
        targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.
        scaleOrLength - for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For Java Object types InputStream and Reader, this is the length of the data in the stream or reader. For all other types, this value will be ignored.
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or if the Java Object specified by x is an InputStream or Reader object and the value of the scale parameter is less than zero

        Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setCharacterStream which takes a length parameter.

        Parameters:
        parameterIndex - the first parameter is 1, the second is 2, ...
        reader - the java.io.Reader object that contains the Unicode data
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method

      • setNCharacterStream

        void setNCharacterStream(int parameterIndex,
                                 Reader value)
                          throws SQLException
        Sets the designated parameter to a Reader object. The Reader reads the data till end-of-file is reached. The driver does the necessary conversion from Java character format to the national character set in the database.

        Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

        Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setNCharacterStream which takes a length parameter.

        Parameters:
        parameterIndex - of the first parameter is 1, the second is 2, ...
        value - the parameter value
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs; or this method is called on a closed PreparedStatement
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method

      • setClob

        void setClob(int parameterIndex,
                     Reader reader)
              throws SQLException
        Sets the designated parameter to a Reader object. This method differs from the setCharacterStream (int, Reader) method because it informs the driver that the parameter value should be sent to the server as a CLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARCHAR or a CLOB

        Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setClob which takes a length parameter.

        Parameters:
        parameterIndex - index of the first parameter is 1, the second is 2, ...
        reader - An object that contains the data to set the parameter value to.
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatementor if parameterIndex does not correspond to a parameter marker in the SQL statement
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method
        Since:
        1.6
      • setBlob

        void setBlob(int parameterIndex,
                     InputStream inputStream)
              throws SQLException
        Sets the designated parameter to a InputStream object. This method differs from the setBinaryStream (int, InputStream) method because it informs the driver that the parameter value should be sent to the server as a BLOB. When the setBinaryStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARBINARY or a BLOB

        Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setBlob which takes a length parameter.

        Parameters:
        parameterIndex - index of the first parameter is 1, the second is 2, ...
        inputStream - An object that contains the data to set the parameter value to.
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or if parameterIndex does not correspond to a parameter marker in the SQL statement,
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method

      • setNClob

        void setNClob(int parameterIndex,
                      Reader reader)
               throws SQLException
        Sets the designated parameter to a Reader object. This method differs from the setCharacterStream (int, Reader) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGNVARCHAR or a NCLOB

        Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setNClob which takes a length parameter.

        Parameters:
        parameterIndex - index of the first parameter is 1, the second is 2, ...
        reader - An object that contains the data to set the parameter value to.
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs or this method is called on a closed PreparedStatement
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method

      • setObject

        default void setObject(int parameterIndex,
                               Object x,
                               SQLType targetSqlType,
                               int scaleOrLength)
                        throws SQLException

        Sets the value of the designated parameter with the given object. If the second argument is an InputStream then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a SQLException when the prepared statement is executed.

        The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

        Note that this method may be used to pass database-specific abstract data types.

        The default implementation will throw SQLFeatureNotSupportedException

        Parameters:
        parameterIndex - the first parameter is 1, the second is 2, ...
        x - the object containing the input parameter value
        targetSqlType - the SQL type to be sent to the database. The scale argument may further qualify this type.
        scaleOrLength - for java.sql.JDBCType.DECIMAL or java.sql.JDBCType.NUMERIC types, this is the number of digits after the decimal point. For Java Object types InputStream and Reader, this is the length of the data in the stream or reader. For all other types, this value will be ignored.
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement or if the Java Object specified by x is an InputStream or Reader object and the value of the scale parameter is less than zero
        SQLFeatureNotSupportedException - if the JDBC driver does not support the specified targetSqlType

                        throws SQLException
        Sets the value of the designated parameter with the given object. This method is similar to setObject(int parameterIndex, Object x, SQLType targetSqlType, int scaleOrLength), except that it assumes a scale of zero.

        The default implementation will throw SQLFeatureNotSupportedException

        Parameters:
        parameterIndex - the first parameter is 1, the second is 2, ...
        x - the object containing the input parameter value
        targetSqlType - the SQL type to be sent to the database
        Throws:
        SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
        SQLFeatureNotSupportedException - if the JDBC driver does not support the specified targetSqlType

      • executeLargeUpdate

        default long executeLargeUpdate()
                                 throws SQLException
        Executes the SQL statement in this PreparedStatement object, which must be an SQL Data Manipulation Language (DML) statement, such as INSERT, UPDATE or DELETE; or an SQL statement that returns nothing, such as a DDL statement.

        This method should be used when the returned row count may exceed Integer.MAX_VALUE.

        The default implementation will throw UnsupportedOperationException

        Returns:
        either (1) the row count for SQL Data Manipulation Language (DML) statements or (2) 0 for SQL statements that return nothing
        Throws:
        SQLException - if a database access error occurs; this method is called on a closed PreparedStatement or the SQL statement returns a ResultSet object
        SQLTimeoutException - when the driver has determined that the timeout value that was specified by the setQueryTimeout method has been exceeded and has at least attempted to cancel the currently running Statement
