MySQL 187

This error occurs when a non-grouping field is used in a clause that requires a grouping field. It is a MySQL syntax error that indicates an incorrect query structure.

How It Affects Your App

The error message indicates that the application is attempting to use a non-grouping field in a GROUP BY clause. This can cause the application to return incorrect results, as the query will not be able to group the data correctly. This can lead to incorrect calculations, incorrect data being displayed, or other unexpected results. Additionally, the application may experience performance issues due to the incorrect query. It is important to ensure that the correct fields are used in the GROUP BY clause in order to ensure the application is functioning correctly.
