Greetings,
Hope you are safe and doing great,

This post describes the things I've done during 8-14 June under the mentor-ship of Sergei Golubchik and Oleksandr Byelkin for GSoC-20 to implement MDEV-12326.

The tasks taken up for this week was to work towards extending the parser for multi-table DELETE....RETURNING by changing the sql_yacc.yy file, for incorporating opt_returning rule in multi-delete query format. The RETURNING_SYM in opt_returning rule incorporates the RETURNING keyword and works completely fine with <column_names> but for some reason it fails and crashes the server for RETURNING * . I'll try to run it in a debugger and will try to fix it soon. Meanwhile, I'll also be pushing the code on this branch (https://github.com/MariaDB/server/pull/1590/commits).

Thank you

Regards,
Mohammed Hammaad Mateen
