What Causes MySQL Error #2014:

MySQL Error #2014: Commands Out of Sync

When defining and attempting to execute a stored procedure, a user encountered the MySQL error #2014 accompanied by the message "Commands out of sync; you can't run this command now." This error occurs when commands are executed in an improper order, particularly when using client functions.

According to MySQL's reference manual, this error specifically indicates that client functions are being called in the incorrect sequence. For instance, when using mysql_use_result(), executing a new query before calling mysql_free_result() may trigger this error. Similarly, attempting two data-returning queries without invoking mysql_use_result() or mysql_store_result() in between can also cause this issue.

A discussion on the MySQL forums suggests that the issue may stem from the tool being used. In a post, a user solved the problem by switching from MySQL Query Browser to MySQL-Front. This suggests that the error may not originate from the server or database but rather from the specific tool employed to execute it.
