Greetings, Hope you are safe and doing great, This post describes the things I've done in my fourth week [25-31 May] of Community Bonding Period under the mentor-ship of Sergei Golubchik and Oleksandr Byelkin for GSoC-20. The tasks taken up for this week was to study and analyze *INSERT SELECT RETURNING* and developing a test suite for *MULTIPLE TABLE DELETE RETURNING.* The following attachment contains the test cases for evaluating Multiple Delete Returning, as they are developed before actual implementation of code, please do notify me of any improvement needed, I'd be glad to resolve. Regards, Mohammed Hammaad Mateen
