BUG: SELECT w/ Correlated Subquery Can Result in Error 403

MORE INFORMATION

This problem is specific to the structure of the SELECT statement. If any part of the statement is altered the error will not be raised.

For example, if the following tables are created:

   CREATE TABLE t1 (c1 int, c2 int)
   CREATE TABLE t2 (c1 int, c2 int)
				

The following select statement will demonstrate the problem:

   SELECT t2.c1, (SELECT COUNT(DISTINCT t1.c1) FROM t1 WHERE t1.c2 =
   t2.c2) FROM t2 WHERE t2.c1<>2
				

If the final restriction clause is changed to 'column > constant', thus:

   SELECT t2.c1, (SELECT COUNT(DISTINCT t1.c1) FROM t1 WHERE t1.c2 =
   t2.c2) FROM t2 WHERE t2.c1>2
				

the statement will be executed as expected. If the DISTINCT clause is removed from the subquery again, the query will execute as expected.
