    Hi Guys,

    I Just wanted to know the difference between the below two tables which one should i prefer to use in procedure(s)?

    DECLARE @SelectDevicesTable table (

    RowId bigint IDENTITY (1, 1) NOT NULL

    ,sDeviceRegId varchar(20))

    OR

    CREATE TABLE #SelectDevicesTable (

    RowId bigint IDENTITY (1, 1) NOT NULL

    ,sDeviceRegId varchar(20))

    Please if possible provide some articles for further studies

    Thanks

    You're welcome.

    You will find lots of good articles here at SQL Server Central. When you want to know more on a particular subject, try searching the articles and I'm sure lots of great stuff will come up.

    Agreed... it's one of the better articles on Table Variable v.s. Temp Tables that I've ever seen.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
