DB2 MAY ISSUE SQL0344N COMPILING A QUERY REFERENCING A VIEW WITH COALESCE OR VALUE IN ITS OUTPUT LIST |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
DB2 may issue sqlcode SQL0344N compiling a query that references
a view which was created with the COALESCE or VALUE function in
its output list.
The sqlcode will be issued only if all the following conditions
are satisfied:
- The view was created on DB2 Version 9.5 GA, Fix Pack 1 or Fix
Pack 2
- The output of the first parameter of the COALESCE or VALUE
function is not nullable
- The output of the first parameter of the COALESCE or VALUE
function flows a default value
An example scenario:
In Fix Pack 2:
CREATE TABLE T (C INT NOT NULL WITH DEFAULT 2);
CREATE VIEW V (VAL_C) AS SELECT VALUE(C, 1) FROM T;
SELECT VAL_C FROM V; -- <-- works fine
In Fix Pack 3:
SELECT VAL_C FROM V; -- <-- SQL0344N issued
SQL0344N The recursive common table expression "<schema>.V" has
mismatched
data types, lengths or code pages for column "VAL_C".
