Description:
HAVING clause against a qualified view column fails to resolve the column name.

How to repeat:
DROP TABLE IF EXISTS t1;
DROP VIEW IF EXISTS v1;
CREATE TABLE t1 ( a int, b int );
INSERT INTO t1 VALUES (1,1),(2,2),(3,3);
CREATE VIEW v1 AS SELECT a,b FROM t1;
SELECT t1.a FROM t1 GROUP BY t1.a HAVING t1.a IN (1,2,3);
SELECT v1.a FROM v1 GROUP BY v1.a HAVING v1.a IN (1,2,3);

-- ERROR 1054 (42S22): Unknown column 'v1.a' in 'having clause'

Suggested fix:
n/a

We need to add another SELECT to the test case above, as the patch does not fix cases where view name has been aliased.

New test case:

DROP TABLE IF EXISTS t1;
DROP VIEW IF EXISTS v1;
CREATE TABLE t1 ( a int, b int );
INSERT INTO t1 VALUES (1,1),(2,2),(3,3);
CREATE VIEW v1 AS SELECT a,b FROM t1;
SELECT t1.a FROM t1 GROUP BY t1.a HAVING t1.a IN (1,2,3);
SELECT t_1.a FROM t1 AS t_1 GROUP BY t_1.a HAVING t_1.a IN (1,2,3);
SELECT v1.a FROM v1 GROUP BY v1.a HAVING v1.a IN (1,2,3);
SELECT v_1.a FROM v1 AS v_1 GROUP BY v_1.a HAVING v_1.a IN (1,2,3);

-- ERROR 1054 (42S22): Unknown column 'v_1.a' in 'having clause'
