    Hi,

    I have a requirement to pass table name as parameter to a procedure and then based on that the procedure has to update some records in that table.

    Could you please give syntax for the same ?

    Regards

    if the tablename is a parameter, then you must use dynamic sql.

    here's an example:

    --for users who are too lazy to type "SELECT * FROM"

    CREATE procedure sp_show

    --USAGE: sp_show gmact

    @TblName varchar(128)

    --WITH ENCRYPTION

    As

    Begin

    exec('Select * from ' + @TblName)

    End

    Just in case @TblName has space or another special charachter:

    exec('Select * from ' + QUOTENAME(@TblName) )
