["Sven Boden (JIRA)" <ib...@incubator.apache.org>]

Sven Boden commented on IBATIS-303:
-----------------------------------

It's a known problem, and it's not going to be solved. It's not in iBATIS, it's a problem with Oracle's driver. 

The JDBC spec allows vendors to skip certain functionality in executeBatch and this is what Oracle does, they return -2 for updates in executeBatch which iBATIS translates to 0. Oracle just doesn't return the number of rows being updated for prepared statements.

>From the Oracle 9i documentation: "For a prepared statement batch, it is not possible to know the number of rows affected in the database by each individual statement in the batch. Therefore, all array elements have a value of -2. According to the JDBC 2.0 specification, a value of -2 indicates that the operation was successful but the number of rows affected is unknown."
