I can guarantee that this behavior happened then. I haven't tested it since then, and using ORM probably makes this moot anyway. But since you're all having so much fun commenting on a 5-year old post, go for it. After, you and Ricky can go find a post from 2003 complaining that T-SQL doesn't have try/catch statements, and call that bullshit too. Okay, I wrote this like 5 years ago.

Sounds more like your app didn't handle a result that the query could have returned. I use Select * in some code (& Select field1, field2 etc in other code) because I want all fields & my code is robust enough to handle whatever result the query returns. Also what Ricky says about BS is correct. Select * is wrong because it broke your app ? Sounds more like your app didn’t handle a result that the query could have returned.

This means that if you add a field to a table, an existing SELECT * query will not return the field!." This is certainly bullshit. “When you run a SELECT *, most databases will cache which fields are returned from this. This means that if you add a field to a table, an existing SELECT * query will not return the field!.”

This is certainly bullshit.

I could be wrong, but I think it has something to do with how COUNT(column) interacts with NULL... possibly in the context of indexing.
