Problem IC67184
|
Status: Closed |
PREDICATE OF THE FORM "<CONCAT EXPRESSION> = G'CONSTANT'" RESULTS IN WRONG DATA RETURNED FROM QUERY |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
A query containing a predicate of the form "<CONCAT expression>
= G'constant'" may return wrong results. The CONCAT expression
must be a concatenation of one or more GRAPHIC columns or
GRAPHIC constants and the result size of each side of the
predicate must be the same. Here are some examples of
problematic queries:
CREATE TABLE T1 ( G1 GRAPHIC(4), G2 GRAPHIC(3)) );
SELECT * FROM T1 WHERE ( G1|| G2 ) = G'ABCDXYZ';
SELECT * FROM T1 WHERE G'ABCDXYZ' = ( G'ABCD' || G2 ) |

| Local Fix: |
Add one or more trailing spaces to the GRAPHIC constant side of
the predicate:
SELECT * FROM T1 WHERE ( G1 || G2 ) = G'ABCDXYZ ';
SELECT * FROM T1 WHERE G'ABCDXYZ ' = ( G'ABCD' || G2 ) |
