I am brand new to C# and to stackoverflow. I am reviewing questions that I got wrong on a prep test for my MTA certification. Can anyone help me understand what the correct answer is and why? Thank you!

  • A.. you need to check city and reference – Jawad Jun 07 '21 at 00:07
  • sorry, but this isn't really a programming question... this is more "comprehensive reading" on a quite basic level – Franz Gleichmann Jun 07 '21 at 07:16
  • Yeah, you’re probably right. I just started learning programming and the SQL portion is especially intimidating to me. It goes to show that you can deduce some of these. Sorry for asking a silly question- just been overwhelmed heading into the test soon whether I’m ready or not because they are discontinuing it. – theswedeman Jun 08 '21 at 06:12

The correct answer would be A

Firstly it says update only those whose reference is TKY, all answers deal with that.

Secondly the updated region should be Japan, so that rules out B and C

Finally the update should only affect customers in Tokyo, so that leaves only A since it's the only one of the four to limit the update with and city='TOKYO'.

  • Thank you! I need to get my MTA cert to be admitted to the program and I am running out of time since they are discontinuing it! I appreciate your help. I am getting C# but it is somewhat slow going. Thank you! – theswedeman Jun 07 '21 at 00:15
