Problem IC79727
|
Status: Geschlossen |
QUERIES WITH LIKE OPERATORS MIGHT RETURN INCORRECT RESULTS DUE TO AN INVALID HIGHEST PADDING CHARACTER |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
SQL statements with LIKE operators might not return the correct
rows that are expected to be returned. This problem arises when
all the following conditions are met:
a) Unicode database using language aware collation is involved.
b) The SQL statement includes a LIKE predicate or a substring
function involved in a basic predicate.
c) The LIKE predicate compares UTF-8 strings that contains
characters encoded between 0xEE8080 to 0xEFBFBF.
d) The EXPLAIN statement shows the predicate filter rows by
start or stop key predicate.
Affected platforms: AIX 64-bit, Linux 64-bit System z
(linux390), Linux 32-bit, linux 64 bit PPC
After applying a fix pack or an APAR, perform the following
steps:
1. Rebind all packages using the db2rbind all command.
2. Refresh the MQTs using the REFRESH TABLE command. |
