|Sybase error code
You used a non-aggregate function or column reference in the select list or in a nested query block that does not appear
in the GROUP BY clause. In a query using GROUP BY, select list items that are not aggregate functions must also appear in
the GROUP BY clause. If the select list item is a column reference or an alias, you may add the column name or alias to the
GROUP BY clause. If the select list item is a scalar function, ensure that the function's arguments in the GROUP BY clause
match exactly with those in the select list. In some cases, you may want to use the MAX function on the column name (or another
aggregate function) instead of adding the column to the GROUP BY clause.
