Problem IT37674
|
Status: Closed |
WRONG RESULTS FROM SELECT COUNT QUERY ON "ORGANIZE BY COLUMN" TABLE
|
| product: |
DB2 FOR LUW / DB2FORLUW / B50 - DB2 |
| Problem description: |
Inconsistent results are possible when SELECT COUNT query is
executed on "ORGANIZE BY COLUMN" table.
The issue is happening due to internal dictionary and encoding
optimizations.
Query has to have an equality predicate.
Example:
select count(*) from t1 where myint=563422
The issue does not happen if the predicate is changed to use
"like" or an arithmetic operation:
select count(*) from t1 where myint like '563422%'
select count(*) from t1 where (myint*2) = 1126844 |
