The following query works and gives the correct answer for SQLite version 3.8.10 but fails to compile with a "misuse of aggregate" error for 3.8.11. CREATE TABLE t1(a int, b int); INSERT INTO t1 VALUES(1,2),(1,18),(2,19); SELECT x, y FROM ( SELECT a AS x, sum(b) AS y FROM t1 GROUP BY a UNION SELECT 98, 99 ) AS w WHERE y>=20; The problem seems to have been introduced by check-in [6df18e949d36] on 2015-06-02. The problem was reported on the sqlite-users mailing list by Jean-Luc Hainaut. |
