I remember I read about this once. Is it really faster to list all desired columns instead of simply using * even if all columns are needed?
Thanks,

I have never, never seen the debate about select column-list vs. select * be about performance of the query when the results are exactly the same.
The question should always be, when deciding between the forms, which is more maintainable, and the answer depends on turn on the query’s use.
