cubrid_unbuffered_query
(PECL CUBRID >= 8.3.0)
cubrid_unbuffered_query — Perform a query without fetching the results into memory
Description
cubrid_unbuffered_query
( string $query
[, resource $conn_identifier
] ) : resource
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 request 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
Example #1 cubrid_unbuffered_query() example
