MariaDB Error 1385: Missing GROUP BY in Procedure
Description
This error indicates that a `SELECT` statement within a stored procedure is attempting to use aggregate functions or non-aggregated columns in a way that necessitates a `GROUP BY` clause, but one is missing. MariaDB requires explicit grouping for such queries to correctly process and return results within the procedural context.
Error Message
Select must have a group with this procedure
Known Causes
3 known causesMissing GROUP BY Clause
A `SELECT` statement within the procedure uses aggregate functions (e.g., `SUM()`, `COUNT()`) without a corresponding `GROUP BY` clause for non-aggregated columns.
Non-Aggregated Columns in SELECT List
The `SELECT` list contains both aggregate functions and non-aggregated columns that are not listed in the `GROUP BY` clause, leading to ambiguity.
Incorrect GROUP BY Columns
The `GROUP BY` clause exists but does not include all non-aggregated columns present in the `SELECT` list, violating SQL grouping rules.
