    Hello all,

    I am trying to pass table name as parameter.

    my code is like

    declare @value varchar(50)

    set @value='select name from sysobjects where name=?'

    select * from @value

    but this is giving me error like "must declare the variable @value.

    Do we have any other option from where i can do this.

    Need your help.

    not sure what exactly you are looking for. it kind of looks like you wnat to test if a table exists?

    this code example works, but might not be what you are after:

    declare @value varchar(50)

    SET @value = 'TallyCalendar'

    select name from sysobjects where name=@value

    --Or?

    select name from sysobjects where name like @value+ '%'

    if you are trying to check if a table exists or not, I usaually use somethign like this:

    --does not exist test

    IF (OBJECT_ID(N'TallyCalendar') IS NULL)

    BEGIN

    --Do Stuff

    print 'Create Table ?'

    END

    --really does exist test

    IF (OBJECT_ID(N'Invoices') IS NOT NULL)

    BEGIN

    --Do Stuff

    print 'INSERT INTO Table ?'

    END

    Sounds like dynamic sql. You can't create a varchar variable and then select from it. You would build your string as you did and then execute it via sp_executesql.

    Been a LONG time since I did anything with DTS but there may be some other that are more current with it.

    This might help.

    declare @value varchar(50) = 'Test'

    declare @query varchar(max)

    Set @query = 'Select * From'+' '+@value+';'

    Execute (@query)
