cubrid_unbuffered_query

(PECL CUBRID >= 8.3.0)

cubrid_unbuffered_queryPerform a query without fetching the results into memory

Description

resource cubrid_unbuffered_query ( string $query [, resource $conn_identifier ] )

This function performs a query without waiting for that all query results have been complete. It will return when the results are being generated.

Parameters

query

A SQL query.

conn_identifier

The CUBRID connection. If the connection identifier is not specified, the last connection opened by cubrid_connect() is assumed.

Return Values

For SELECT, SHOW, DESCRIBE or EXPLAIN statements returns a connection identifier resource on success.

For other type of SQL statements, UPDATE, DELETE, DROP, etc, returns TRUE on success.

FALSE on failure.

Notes

Note:

The benefits of cubrid_unbuffered_query() come at a cost: you cannot use cubrid_num_rows() and cubrid_data_seek() on a result set returned from cubrid_unbuffered_query().

Examples

    }
    
$query "select * from code";
