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.

Anmerkungen

Hinweis:

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().
