Currently when using Data Compare for Oracle 4 if any INSERT/UPDATE throws an error in a PL/SQL block the entire block fails. Because of this the company I work for will not use the software for DML deployments. If Redgate could code error handling for each table or each block where the script will continue to update/insert SQL data even in the event of an error the software would be much more usable, robust, and practical. Thank-you for reading this. :) Please add error-handling to the DML code that is generated in the diff/sync scripts.
