this is incompatible with sql_mode=only_full_group_by ; bad SQL grammar
Hi there! It seems like you're encountering an error related to the SQL mode "only_full_group_by". This mode is a stricter setting that requires all columns in the SELECT statement to be either aggregated or included in the GROUP BY clause.
If you're getting an error message stating that your query is incompatible with "sql_mode=only_full_group_by" or experiencing a "bad SQL grammar" issue, it means that your query violates this condition.
To resolve this error, you have a few options:
1. Adjust your SQL query: Make sure that all non-aggregated columns in the SELECT statement are also included in the GROUP BY clause. This ensures that your query conforms to the "only_full_group_by" mode.
2. Disable the "only_full_group_by" mode: If you have the necessary privileges, you can modify the SQL mode settings to disable "only_full_group_by". However, keep in mind that this might have implications on the correctness and reliability of your query results.
3. Use an aggregate function for non-grouped columns: Another way to address this error is to use an appropriate aggregate function, such as MAX(), MIN(), SUM(), etc., for the non-aggregated columns in your SELECT statement.
Please provide more details about your specific SQL query or error message if you need further assistance.
