I have group by query which works fine in PHP PDO but when I add "sql_mode = ONLY_FULL_GROUP_BY" in mysql ini, the same query fails with an error SQLSTATE[42000]: Syntax error or access violation: 1055 'db.table.t_date' isn't in GROUP BY The actual query <pre><code>SELECT * FROM ( SELECT DATE_FORMAT(t_date, '%b') AS mon, DATE_FORMAT(t_date, '%Y-%m') AS fy_date, (SUM(val1) - SUM(val2)) AS net_val FROM TABLE GROUP BY YEAR(t_date), MONTH(t_date) ORDER BY DATE_FORMAT(t_date, '%Y-%m') DESC LIMIT 12 ) AS tbl ORDER BY fy_date </code></pre> Can someone please tell why the above query is not working with <pre><code>sql_mode = ONLY_FULL_GROUP_BY </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
