|
Status: Geschlossen |
UPDATE ON FULL TABLE WHICH USES SUB_SELECT COULD INCORRECTLY SET VALUES TO NULL FOR COLUMN BEING UPDATED.
|
| Produkt: |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 |
| Problembeschreibung: |
Update using a sub-select on the full table could incorrectly
set column value to NULL.
Single row update is correct and is setting a proper value for
the column.
The problem only exists in v11.
example:
update test1 t1 set col_a = (select t2.col_a from test2 t2
where t1.col_a = t2.col_a)
col_a will be updated to NULL incorrectly. |
