Comment on I accidentally removed the WHERE clause from my SQL query in a personal tool. Every row is now the same. I lost everything, have no backup, and I'm stupid.

You’re not the first. You won’t be the last. I’m just glad my DB of choice uses transactions by default, so I can see “rows updated: 3,258,123” and back the fuck out of it.

I genuinely believe that UPDATE and DELETE without a WHERE clause should be considered a syntax error. If you want to do all rows for some reason, it should have been something like UPDATE table SET field=value ALL.

Because I’m relatively new at this type of thing, how does that appear on the front end? I’m using a js/html front end and a jsnode backend. Would I just see a popup before I make any changes?

  If you’re asking about the information about the number of rows, oracle db clients do that. For nodejs, oracle’s library will provide this number in the response to a dml statement execution. So you can retrieve it in your backend code. You have to write additional code to bring this message to the front-end.

    Awesome, thanks for the info. Definitely super useful for debug mode whilst I’m fixing and tampering!

  No idea. My tools connect directly to the DB server, rather than going though any web server shenanigans.
