Incorrect syntax near the keyword 'with'.

Question

Hello I\'m trying to figure out why switching my compatability mode from 80 to 100 in MSSQL broke my function below?

    Microsoft SQL Server 2008 R2 (RTM)

I would suggest that you adopt the practice of ending all statements with a semicolon. This is part of the ANSI standard and will help you when need to work on another database. SQL Server are moving towards this in any case. Many more commands require semicolons now in SQL Server 2012.

E.g.

ALTER FUNCTION [dbo].[GetRoot] 
    (@Param1 int)
RETURNS varchar(50)
AS
BEGIN
    DECLARE @ReturnValue VARCHAR(50)
    ;
    WITH cteResults 
    AS (SELECT parentouid
              ,net_ouid 
          FROM net_ou 
         WHERE net_ouid=@Param1
         UNION ALL
        SELECT t2.parentouid,t2.net_ouid 
          FROM net_ou t2 
         INNER JOIN results t1 
                 ON t1.parentouid = t2.net_ouid
         WHERE t2.parentouid <> t1.net_ouid )   
    SELECT @ReturnValue = net_ou.displayname 
      FROM net_ou 
     RIGHT JOIN cteResults 
             ON net_ou.net_ouid = results.ParentouID
     WHERE results.parentouid=results.net_ouid
    ;   
    RETURN @ReturnValue
    ;   
END
;
GO

As an added bonus it makes you queries a crap load easier to read. ;-)
