Subject [jira] Created: (DERBY-2016) ArrayIndexOutOfBoundsException for COALESCE with aggregate functions
Date Sun, 29 Oct 2006 14:58:16 GMT
ArrayIndexOutOfBoundsException for COALESCE with aggregate functions
--------------------------------------------------------------------

                 Key: DERBY-2016
                 URL: http://issues.apache.org/jira/browse/DERBY-2016
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.2.1.6
         Environment: 1.5.0_06-b05
            Reporter: Christian d'Heureuse


The following statements produce an ArrayIndexOutOfBoundsException:

CREATE TABLE t1 (
   f1 INTEGER);

SELECT COALESCE(MAX(f1),0) FROM t1;

Workaround:
   VALUES COALESCE( (SELECT MAX(f1) FROM t1), 0);
