Parameter passing to a function

i HAVE DEFINE THE FOLLOWING FUNCTION WITH THREE PARAMETERS.


ALTER FUNCTION [dbo].[fn_threeyearsalessolo](
      @clientid varchar(10),
        @stdate datetime,
        @edate datetime
      )
RETURNS money
AS
-- Returns Sales for past three years for solo practitioners
BEGIN
    DECLARE @ret money;
    SELECT @ret = SUM(total_charges)
    FROM orders o
    WHERE o.bt_id = @clientid and (o.order_date >= dateadd("YYYY",-3,@stdate) and o.order_date <= @edate
        and o.status not like 'C%' and balance = 0;
     IF (@ret IS NULL)
        SET @ret = 0;
    RETURN @ret;
END;



Yet when I try to call the function using the following code

Update BM_OnlinePass_SubscriberandSales      
set threeyearsales = dbo.fn_threeyearsalessolo(clientid,@STDATE,@EDATE)  
where company_record = 0

  SQL says function call has too many arguments????

Am I defining the correct type of function?   Scalar

There appears to be some incorrect bracketing:

WHERE o.bt_id = @clientid and (o.order_date >= dateadd("YYYY",-3,@stdate) and o.order_date <= @edate

should be

WHERE o.bt_id = @clientid and o.order_date >= dateadd("YYYY",-3,@stdate) and o.order_date <= @edate

Try that? Doubt that's it. I assume a copy and paste error.

you are missing a parenthesis here before 'and o.order_date '

 WHERE o.bt_id = @clientid and (o.order_date >= dateadd("YYYY",-3,@stdate)      )      and o.order_date <= @edate

Scott PletcherSenior DBACommented:
The date part, the first parameter, in DATEADD is not a literal but a keyword, i.e., no quotes around YEAR.  Since all connectors are "AND", you don't parentheses anyway.  

The current error occurred because the previous ALTER failed, therefore you didn't replace the existing function with one that had 3 parameters.


ALTER FUNCTION [dbo].[fn_threeyearsalessolo](
       @clientid varchar(10),
       @stdate datetime,
       @edate datetime
       )
RETURNS money
AS
-- Returns Sales for past three years for solo practitioners
BEGIN
RETURN ISNULL((
     SELECT SUM(total_charges)
     FROM orders o
     WHERE
        o.bt_id = @clientid and
        o.order_date >= dateadd(YEAR,-3,@stdate) and
        o.order_date <= @edate and
        o.status not like 'C%' and
        balance = 0
), 0)
END --FUNCTION

Kudos for quick and accurate analysis.. date utils in Crysta/SQL always spin me silly

Corrected the issue and made my deadline..
