(PECL CUBRID >= 8.3.0)
cubrid_unbuffered_query — Perform a query without fetching the results into memory

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

For other type of SQL statements, UPDATE, DELETE, DROP, etc, returns TRUE on success.
FALSE on failure.
注释
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().
