I accidentally removed the WHERE clause from my SQL query in a personal tool. Every row is now the same. I overwrote 206,000+ rows. I have no backup, I am stupid. (lemmy.world)

"UPDATE table_name SET w = $1, x = $2, z = $4 WHERE y = $3 RETURNING *",

does not do the same as

"UPDATE table_name SET w = $1, x = $2, y = $3, z = $4 RETURNING *",

It's 2 am and my mind blanked out the WHERE, and just wanted the numbers neatly in order of 1234.

idiot.

FML.

I tried to find this setting for postgres and Ms SQLserver, the two databases I interact with. I wasn't able to find any settings to that effect, do you happen to know them?

for postgres and Ms SQLserver

It's not really a SQL Language feature, more an IDE feature. So to tell you where the settings are, we'd have to know which IDE you're using.

For example, in DataGrip (which I think you can use both for postgres and MSSQL), there's "Show warning before running potentially unsafe queries"

If you forgot to put the WHERE clause in DELETE and UPDATE statements, DataGrip displays a notification to remind you about that. If you omitted the WHERE clause intentionally, you can execute current statements as you planned.

That would be SQL management studio and psql on the command line.

The best I could find was some plugins for SQL management studio (ssmsboost) and disable automatic commits for psql.

I didn't mean this as IDE thing, there is an extension to postgres and server configuration for mysql/mardiadb. Posted the links above

I didn’t mean this as IDE thing

Well, the link you've posted is specifically for MySQL CLI Client - Maybe I should have I said "Client" instead of "IDE" - but if he uses a different IDE/Client besides MySQL-CLI it's probably a different setting
