Either this or the \f[B]mysql_store_result(3)\f[R] function must be called before the results of a query can be retrieved, and one or the other must be called to prevent the next query on that database connection from failing. .SS Parameters .IP \[bu] 2 \f[C]mysql\f[R] is a connection identifier, which was previously allocated by \f[B]mysql_init(3)\f[R] and connected by \f[B]mysql_real_connect(3)\f[R]. .SS Notes .PP The mysql_use_result() function does not transfer the entire result set. Hence several functions like \f[B]mysql_num_rows(3)\f[R] or \f[B]mysql_data_seek(3)\f[R] cannot be used. mysql_use_result() will block the current connection until all result sets are retrieved or result set was released by \f[B]mysql_free_result(3)\f[R]. .SS Return value .PP Returns an unbuffered result set or \f[C]NULL\f[R] if an error occurred. .SS See also .IP \[bu] 2 \f[B]mysql_store_result(3)\f[R] .IP \[bu] 2 \f[B]mysql_free_result(3)\f[R]
