Code Inspection: Column should be in group by clause

Reports columns that are not in the GROUP BY clause or inside an aggregate function call.

Example (Microsoft SQL Server):

CREATE TABLE t1 (a INT, b INT); SELECT a, b FROM t1 GROUP BY a;


If you run the SELECT query, you will receive an error because Microsoft SQL Server expects the b column in GROUP BY or used inside an aggregate function. The following two examples will fix the error.
SELECT a, b FROM t1 GROUP BY a, b; SELECT a, max(b) max_b FROM t1 GROUP BY a;

  2. Click the arrow next to the inspection you want to suppress and select the necessary suppress action.
