Greetings, Hope you are safe and doing great, This post describes the things I've done in my second week [ 11-17 May ] of Community Bonding Period under the mentor-ship of Sergei Golubchik and Oleksandr Byelkin for GSoC-20. Tasks done this week were mostly the continuation of the leftover tasks from the previous week and some related study. Things I've done include: 1:* I was caught up in analysing how was DELETE .... RETURNING implemented, which led me to read from:* • *sp_head.cc* : this made me understand that sp actually meant stored procedures but there is another called PS which I'm yet to figure out. • *sql_parse.cc* : from here I understood that delete return as actually { Analyse->Delete->Return } and all the logic for returning is executed if(lex->has_returning()). 2: Though I've raised the pull request, *MDEV-14558* is not yet completely tested as it does not include tests for *mysql \s*, moreover, I'm facing problems to escape the backslash inorder to write a test-case for *mysql \s* .
