Knut Anders Hatlen resolved DERBY-4385.
---------------------------------------

    Resolution: Duplicate

It works as expected with 10.5.3.0 and trunk. Probably a duplicate of DERBY-4001.

> Consider the following:
> CREATE TABLE t1 (i INT PRIMARY KEY, j INT);
> CREATE TABLE t2 (i INT);
> INSERT INTO t1 VALUES (1,1),(2,2);
> INSERT INTO t2 VALUES (81);
> The two following queries should give the same result:
> SELECT * FROM t1 WHERE i < ALL (SELECT i FROM t2);
> SELECT * FROM t1 WHERE i < ALL (SELECT 81 FROM t2);
> But, they don't:
> ij> SELECT * FROM t1 WHERE i < ALL (SELECT i FROM t2);
> I          |J          
> -----------------------
> 1          |1          
> 2          |2          
> 2 rows selected
> ij> SELECT * FROM t1 WHERE i < ALL (SELECT 81 FROM t2);
> I          |J          
> -----------------------
> 0 rows selected
> ij>
