keeping a table variable alive

    Hi,

    I'm following some tutortials at the moment that ask me to create @table variables. I find that I have to run the entire script over and over again to get my results as the table variable is only alive when running the scripts.

    Is there an enviroment or session variable I can set that will keep the variable alive during my session without having to include in my script every time?

    Any help welcome on this.

    thanks,

    No, this is the way that table variables are supposed to work.

    What you can do is change all of the "DECLARE @TABLE TABLE" statements to "CREATE TABLE #TABLE", then change @TABLE to #TABLE everywhere in your code. It will then persist until explicitly dropped, or the connection is closed.

    Or plan B if you'd rather not wait... just add this where you need to debug

    SELECT * FROM #tmp from @table
