PHP 5.3：mysqli_multi_query和“命令不同步”错误

Question

When I use mysqli_multi_query() with a mass INSERT query, then after the query has run do another query using mysqli_query('SELECT...'), I get "commands out of sync" errors. Does anyone know why this happens?

Answer 1

You've to call mysqli_use_result (or mysqli_store_result ) after a mysqli_multi_query() call.

Lower level documentation about this error: http://dev.mysql.com/doc/refman/5.1/en/commands-out-of-sync.html

Answer 2

Use mysqli_next_result($db) , after freeing the result set if any . This alone would fix the out of sync issues.
