[jira] [Updated] (DERBY-6417) Dropping a column in 10.7 release
when there is a trigger with REFERENCING OLD clause defined on the table
gives error "ERROR 42X05: Table/View 'OLD' does not exist.".
[ https://issues.apache.org/jira/browse/DERBY-6417?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Knut Anders Hatlen updated DERBY-6417:
--------------------------------------
Fix Version/s: (was: 10.11.1.2)
(was: 10.10.2.0)
(was: 10.9.2.2)
(was: 10.8.3.3)
Marking as a regression, since it works as expected on the 10.7.1.1 release and fails on the head of the 10.7 branch. The regression does not seem to affect the other branches.

> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.7.1.4
> Reporter: Mamta A. Satoor
>
> While working on DERBY-6383, wrote a junit test case to test the impact of DROP COLUMN on the triggers, found following incorrect behavior with 10.7 release. The behavior is correct on 10.8 and higher releases
> CREATE TABLE DERBY_6368_TAB1 (X INTEGER, Y INTEGER);
> CREATE TABLE DERBY_6368_TAB2 (X INTEGER, Y INTEGER);
> INSERT INTO DERBY_6368_TAB1 VALUES(1, 2);
> CREATE TRIGGER t3 AFTER UPDATE ON DERBY_6368_TAB1 REFERENCING old table AS old INSERT INTO DERBY_6368_TAB2 SELECT * FROM old;
> --1 row
> UPDATE DERBY_6368_TAB1 SET x = x + 1;
> select count(*) from DERBY_6368_TAB2;
> ALTER TABLE DERBY_6368_TAB1 DROP COLUMN Y;
> The ALTER TABLE above gives correct warning in 10.8 and higher as shown below
> WARNING 01502: The trigger T3 on table DERBY_6368_TAB1 has been dropped.
> but 10.7 gives following error
> ERROR 42X05: Table/View 'OLD' does not exist.
