Status: Geschlossen |
WRONG RESULTS WITH LIKE EXPRESSION USING '^' (CIRCUMFLEX ACCENT)AND LANGUAGE AWARE COLLATION SEQUENCE |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problembeschreibung: |
In a unicode database which was created with a "language aware
collation" sequence, like "UCA500R1_LROOT_AN_CX_EX_FX_HX_NX_S2"
we may see wrong results with pattern matching during a
expression using LIKE and the character "^" (CIRCUMFLEX ACCENT).
For example the following query retruns wrong result:
db2 select case when '^' like '^' then 1 else 0 end from
sysibm.sysdummy1
1
-----------
0
This does not happen with the default collating sequence
(IDENTITY). |
