    Using WITH in SQL versus sub-query-which is better?

    Content

    Hi Experts,

    Can someone help me understand if using WITH in SQL query really improve performance versus a sub-query or a scalar inline?
    I don't really see why unnecessary you create a virtual table with tons of data when you will anyhow cut of ahlf of it using the following main query where you are probably going to use the WITH table in an INNERJOIN?
    Isn't a tightly bound sub-query more faster?

    Thanks,
    Aloka
