Problem IC97793
|
Status: Geschlossen |
INCORRECT RESULT IN UNICODE DB WITH LIKE PREDICATE AND FULLWIDTH UNDERSCORE WILD CHARACTER ON A CLOB COLUMN |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problembeschreibung: |
In a unicode database, running a query might return incorrect
results if it contains a like predicate against a clob column,
and the pattern to match contains a fullwidth underscore wild
character (X'EFBCBF').
For example:
create table tbl1 ( id int, cclob20oct clob(20))
insert into tbl1 values (1, X'F094AE8041')
select id from tbl1 where cclob20oct like X'F094AE80EFBCBF'
ID
-----------
0 record(s) selected.
<-- incorrect result returns : the matching row is not returned.
Recall that the fullwidth underscore is a wildcard character.
See the Information Center for details. |
