Function That Works In Sql Server Management Studio Does Not Work In Derived Column Transformation Editor

Hi

I'm a relative SQL Server newbee and have developed a function that converts mm/dd/yyyy to yyy/mm/dd for use as in a DT_DBDATE format for insert into a column with smalldatatime.



I receive the following erros when using the function in the Derived Column Transformation Editor. First, the function, then the error when using it as the expression Derived Column Transformation Editor.



Can anyone explain how I can do this transformation work in this context or suggest a way either do the transformation easier or avoid it altogerher?



Thanks for the look see...

******************************

ALTER FUNCTION [dbo].[convdate]

(

@indate nvarchar(10)

)

RETURNS nvarchar(10)

AS

BEGIN

-- Declare the return variable here

DECLARE @outdate nvarchar(10)

set @outdate =

substring(@indate,patindex('%[1,2][0-9][0-9][0-9]%',@indate),4)+'/'+

substring(@indate,patindex('%[-,1][0-9][/]%',@indate),2)+'/'+

substring(@indate,patindex('%[2,3][0,1,8,9][/]%',@indate),2)



RETURN @outdate

END

********************************



And the error...



expression "lipper.dbo.convdate(eomdate)" failed. The token "." at line number "1", character number "11" was not recognized. The expression cannot be parsed because it contains invalid elements at the location specified.

Error at Data Flow Task [Derived Column [111]]: Cannot parse the expression "lipper.dbo.convdate(eomdate)". The expression was not valid, or there is an out-of-memory error.
