SQL Server 2008 - IF NOT EXISTS INSERT ELSE UPDATE

Question

I apologize, but this is kind of a two part question.

I\'m extremely new to SQL and am trying to develop a time clock application for the small office that I work in

Answer 1

IF NOT EXISTS(SELECT * FROM Clock
WHERE clockDate = '08/10/2012') AND userName = 'test')

Has an extra parenthesis. I think it's fine if you remove it:

IF NOT EXISTS(SELECT * FROM Clock WHERE
clockDate = '08/10/2012' AND userName = 'test')

Also, GETDATE() will put the current date in the column, though if you don't want the time you'll have to play a little. I think CONVERT(varchar(8), GETDATE(), 112) would give you just the date (not time) portion.

IF NOT EXISTS(SELECT * FROM Clock WHERE
clockDate = CONVERT(varchar(8), GETDATE(), 112)
AND userName = 'test')

should probably do it.

PS: use a merge statement :)
