Problem in getting correct update records count while getUpdateCount()

Question

hi,
I have used "Select in Insert" queries for migrating data from one table to another.
like
INSERT INTO TABLE1 (COL1, COL2)
SELECT COL1,COL2,... FROM TABLE2
WHERE COL1 = ... AND COL2 = ...;
Case 1:
I added these statements as addBatch() & at the end i execute method " executeBatch()".
Then i execute
getUpdateCount() method
on that prepareStatement ,but that count was not correct all the time.
Case 2:
If i run the same code with executeUpdate() method , it returned me the correct number of records counts that are inserted into the table.
I cudn't able to understand that it is failing for case1.
Can anybody tell the reason for this behaviour .......................

hi,
Thanks again for a correct reply but can u also tell me tht which jar i needs to included.
There are so many jar files & should i remove old jar files or jvm auto picks the updated jar file.
Following jar files are shown on the link:::
ojdbc5.jar (1,996,228 bytes) - Classes for use with JDK 1.5. It contains the JDBC driver classes, except classes for NLS support in Oracle Object and Collection types.
ojdbc5_g.jar (3,081,328 bytes) - Same as ojdbc5.jar, except that classes were compiled with "javac -g" and contain tracing code.
ojdbc6.jar (2,111,220 bytes) - Classes for use with JDK 1.6. It contains the JDBC driver classes except classes for NLS support in Oracle Object and Collection types.
ojdbc6_g.jar (3,401,519 bytes) - Same as ojdbc6.jar except compiled with "javac -g" and contains tracing code.
ojdbc5dms.jar (2,429,777 bytes) - Same as ojdbc5.jar, except that it contains instrumentation to support DMS and limited java.util.logging calls.
ojdbc5dms_g.jar (3,101,875 bytes) - Same as ojdbc5_g.jar, except that it contains instrumentation to support DMS.
ojdbc6dms.jar (2,655,741 bytes) - Same as ojdbc6.jar, except that it contains instrumentation to support DMS and limited java.util.logging calls.
