Greetings,

Hope you are safe and doing great,

This post describes the things I've done during 1-7 June under the mentor-ship of Sergei Golubchik and Oleksandr Byelkin for GSoC-20. The tasks taken up for this week Greetings mentors, I've realized that to extend the parser for multi delete, I should be changing the sql_yacc.yy file, for incorporating opt_returning rule in multi-delete. opt_returning rule works completely fine with single table delete, but to tweak it to adapt for multi-delete, required me to learn some bison grammar syntax and semantics and that took me a couple of days.

Moreover everytime I made changes to the grammar, the server used to crash rendering all changes invalid. I'll try to push the code that was triggering crashes, shortly.

Thank you

Regards,
