Problems using SQL Queries within ButtonPushed callbacks

Hi all,
I am experiencing an unusual problem within MATLAB App Designer.
I have a button that, when pushed, retrieves information from a database.
Without the SQL query, the ButtonPushed callback functions as expected, but when I add the code to execute the query, the ButtonPushed callback gets executed twice.
I found a solution is to move the SQL query into a separate function and call that from the ButtonPushed callback, but I am wondering why having it directly in the callback function is an issue.
Thanks in advance,
-Mac

Mac,
Can you provide a sample snippet of your push-button callback containing the SQL query code? This will help us to identify the problem.

Solved!
There was an EditField that somehow got mapped to the ButtonPushed callback.
This was the cause of the double trigger.
Thank you.
