Greetings,
Hope you are safe and doing great,

This post describes the things I've done during 15-21 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 and multi-table
UPDATE....RETURNING, side-by-side, thereby changing the sql_yacc.yy file,
for incorporating opt_returning rule in respective query format.

  I've also updated the test suite for multi-table UPDATE.... RETURNING
and  extended the parser by adding select_result parameter in multi-update
and multi-delete functions, so as to enable returning a result set
possible, whenever we query with RETURNING clause.

  All the code is uploaded up to date in these remote repositories, please
feel free to comment.
