I have this query
DECLARE @TheDate DATE
IF @TheDate IS NULL
SET @TheDate = GETDATE()
SET @FileName = 'DailyAgentSales' + CONVERT(CHAR(8) ,@TheDate -1 ,112) + '.csv'
SET @Subject = 'Agent Sales - ' + CONVERT(CHAR(8) ,@TheDate -1 ,112)
And I'm getting this error: Operand type clash: date is incompatible with int,
what it this error and where do I start to look at to solve it?

It's coming from this fragment: @TheDate -1

You can't add or subtract integers from a DATE variable. Try DATEADD(dd,-1,@TheDate) in both places where that occurs

You could also change this...

DECLARE @TheDate DATE

... to this ...

DECLARE @TheDate DATETIME

... and continue to do the -1 trick.

Heh... now duck... here come the DATE/TIME police whose hair just burst into flames. 😛

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
