DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
In a partitioned database environment, if you have a table A
with a LOB column with hundreds of thousands of rows, running
the LOAD FROM CURSOR from table A to a table B
might load incorrect data into the LOB column in table B.
The following example shows an scenario where you can experience
this problem:
1. Create table A and table B with the same definition including
a LOB column.
2. Insert more than one houndred thousand rows in table A.
3. db2 "DECLARE mycurs CURSOR FOR SELECT * FROM A"
4. db2 "LOAD FROM mycurs OF cursor INSERT INTO B"
The LOAD command fetches rows from table A using a cursor and
inserts them
into table B. The LOB columns in table B might have incorrect
data after the
LOAD command is completed. |
