mysql_stmt_store_result — Transfers a result set from a prepared statement
int mysql_stmt_store_result(MYSQL_STMT * stmt);
You must call mysql_stmt_store_result()
for every query that successfully produces a result set (SELECT, SHOW, DESCRIBE, EXPLAIN), and only if you want to buffer the complete result set by the client, so that the subsequent mysql_stmt_fetch()
call returns buffered data.
