Interface DatabaseMetaData

  • All Superinterfaces:
    Wrapper


    public interface DatabaseMetaData
    extends Wrapper
    An interface which provides comprehensive information about the database management system and its supported features.

    This interface is implemented by JDBC driver vendors in order to provide information about the underlying database capabilities in association with the JDBC driver.

    Some of the methods in this interface take string parameters which are patterns. Within these string patterns, '%' and '_' characters have special meanings. '%' means "match any substring of 0 or more characters". '_' means "match any character". Only metadata entries that match the pattern are returned. If such a search pattern string is set to null, that argument's criteria are dropped from the search.

        16. ORDINAL_POSITION - int - The index of the column in the table (where the count starts from 1, not 0)
        17. IS_NULLABLE - String - "NO" = the column does not allow NULLs, "YES" = the column allows NULLs, "" = status unknown
        18. SCOPE_CATALOG - String - if the DATA_TYPE is REF, this gives the catalog of the table corresponding to the attribute's scope. NULL if the DATA_TYPE is not REF.
        19. SCOPE_SCHEMA - String - if the DATA_TYPE is REF, this gives the schema of the table corresponding to the attribute's scope. NULL if the DATA_TYPE is not REF.
        20. SCOPE_TABLE - String - if the DATA_TYPE is REF, this gives the name of the table corresponding to the attribute's scope. NULL if the DATA_TYPE is not REF.
        21. SOURCE_DATA_TYPE - String - The source type for a user generated REF type or for a Distinct type. (NULL if DATA_TYPE is not DISTINCT or a user generated REF)
        Parameters:
        catalog - a catalog name. null is used to imply no narrowing of the search by catalog name. Otherwise, the name must match a catalog name held in the database, with "" used to retrieve those without a catalog name.
        schemaPattern - a schema name pattern. null is used to imply no narrowing of the search by a schema name. Otherwise, the name must match a schema name in the database, with "" used to retrieve those without a schema name.
        typeNamePattern - a type name. This pattern must match the type name stored in the database.
        attributeNamePattern - an Attribute name. This pattern must match the attribute name as stored in the database.
        Returns:
        a ResultSet, where each row is an attribute description.

        2. COLUMN_NAME - String - the column name
        3. DATA_TYPE - int - the Type of the data, as defined in java.sql.Types

        table - the table name. This must match the name of the table as declared in the database.
        scope - the SCOPE of interest, values as defined above.
