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)

Try throwing a semi colon in front of the with:

;with results 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
    )   

Give this article a read to understand why you need to do that. Snipit:

However, if the CTE is not the first statement in the batch, you must precede the WITH keyword with a semicolon. As a best practice, I prefer to prefix all of my CTEs with a semicolon—I find this consistent approach easier than having to remember whether I need a semicolon or not.

Personally, I don't do it for every CTE, but if that makes things easier for you it won't hurt anything.
