PRINT statement in T-SQL

Question

Why does the PRINT statement in T-SQL seem to only sometimes work? What are the constraints on using it? It seems sometimes if a result set is generated, it becomes a null

Answer 1

So, if you have a statement something like the following, you're saying that you get no 'print' result?

select * from sysobjects
PRINT 'Just selected * from sysobjects'

If you're using SQL Query Analyzer, you'll see that there are two tabs down at the bottom, one of which is "Messages" and that's where the 'print' statements will show up.
If you're concerned about the timing of seeing the print statements, you may want to try using something like

raiserror ('My Print Statement', 10,1) with nowait

This will give you the message immediately as the statement is reached, rather than buffering the output, as the Query Analyzer will do under most conditions.
