Status: Closed |
UPDATE STATEMENT WITH CORRELATED SCALAR SUBQUERY FAILS WITH SQLCODE -407
|
| product: |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 |
| Problem description: |
Starting with Db2 v11.1.4.4, an UPDATE statement that includes a
correlated scalar subquery may incorrectly return SQLCODE -407,
SQLSTATE 23502 at run time if the scalar subquery returns a NULL
result.
This may happen even if the assignment of the NULL value is
protected with - for example - COALESCE:
update T set NotNullableColumn = coalesce((select tabname
from syscat.tables where tabname = T.COL1), T.COL2) |
