MySQL #2014 Error: Deciphering "Commands Out of Sync"

When attempting to execute a stored procedure defined as:

delimiter ;;
Create procedure sp_test()

  select * from name_table;
end

a frustrating error #2014 emerges: "Commands out of sync; you can't run this command now."

Root Cause:

This error indicates that commands within the client code are being executed in an incorrect sequence.

Specific Issues Involved:

  1. Using mysql_use_result() and attempting to execute another query before calling mysql_free_result().
  2. Attempting to execute multiple queries that return data without utilizing either mysql_use_result() or mysql_store_result() between each query.

Potential Solution:

Based on observations from the MySQL forums, it appears that this issue may stem from the tool being used rather than a server-side or database-related concern. Consider utilizing an alternative tool such as MySQL-Fron instead of MySQL Query Browser.
