I'm so used to writing:
SELECT * FROM [table name]
That you can bet when it's time to delete I'll write:
DELETE * FROM [table name]
I no longer blame myself. I consider it a language design bug thingy.
Personally I use extension methods when writing LINQ, not the SQL like syntax. Anytime I see the SQL syntax my mind goes blank.

But it's not really a 'bug thingy': You can select * (meaning all) or columns you name when selecting. When you Delete, it's the whole ROW, not columns, hence the */Column names aren't required. :-)

Which is why I have replaced that with
SELECT COUNT(ROWID) FROM [table_name]
Sometimes that by itself will tell me all I need to know. :)

I got into the habit of making myself look at the thing I wanted to delete before deleting.

If get in the habit of putting all your statements inside a transaction, then if you realize you made a mistake you can roll it back without affecting the table. Of course, you have to remember to commit the transaction in a timely manner, otherwise the table remains locked.

I've found a very easy way to completely avoid making any mistakes in SQL: I don't use SQL.
You're lucky man. I often wake up in a cold sweat in the middle of the night wondering if I left out the
WHEREclause when executing aDELETE. :sigh: /raviMy new year resolution: 2048 x 1536 Home | Articles | My .NET bits | Freeware ravib(at)ravib(dot)com

Solid advice but the ONLY time I ever use the delete command is to clear test database tables. I never use delete in production - everything is a log and if the user doesn't want to see it anymore a flag is set on the record. I was getting burned too often by people who would blame me for bad data. Every item and every change is logged and nothing is ever deleted. :^)
Agreed, solid advice, but cloud storage (my company is in Azure now) makes soft deletes expensive. What we've started doing is setting soft deletes on large blobs, then purging those older than 90 days every month or so; if they don't notice it in 90 days, then YAGNI :)

I like doing SELECT COUNT(*) or just SELECT *, making sure my results are valid, then changing it to DELETE. Seems to work for me.

The nice thing about it is that you have so many different standard implementations of SQL to choose from, too!

I also do that. I think it's a bad habit I picked up with Access, because if I recall correctly, you had to say it like that in Access SQL.

I'm not sure, but it may depend on the driver. We use the Jet4 oledb driver for Access and it is quite happy to delete with or without the *. Our apps run can use either SQL Server or Access for the backend, and Delete operations don't require any special handling. (aside from date delimiters) Basically, if it works in Access, it will work in SQL Server, but not always the other way around.
