In this code i am creating the table with code.  Is there any way i could alter the code to SELECT INTO so i don't have to explicitly create the table
?

CREATE TABLE  ##TESTTABLE ([RoomID] varchar(50),  [BuildingID] varchar(100), [Number] varchar(100), [Name] varchar(100))
EXEC (@openrowset)


INSERT INTO ##TESTTABLE([RoomID] ,  [BuildingID] , [Number], [Name] )
EXEC (@openrowset)

so there is no way to read the results of a dynamic query into a table that has not already been created?

what is your @OpenRowSet?

Instead of EXEC, would you be able to do a "select * from OpenRowSet" as shown in https://msdn.microsoft.com/en-us/library/ms190312.aspx?

If you can do this, you will be able to use the INSERT INTO statement and not create a table first.

and BTW, do you know the meaning of ## ? A global temp table is not widely used. Have a look at http://sqlmag.com/t-sql/temporary-tables-local-vs-global

@openrowset was as stupidly named variable. It is a select statement

As the referenced article says: it works with a global temporary table (but not with a local temporay table) to use EXEC. So your dynamic SQL could look like
select ... INTO ##TESTTABLE from ...

Open in new window

But of course you'll need to drop the global temp table yourself, the same as when creating it above.

Have you tried the real OpenRowset method from the links already provided?

I got it working with your help. All i needed to do was to update the dymanic sql with the select into and then run EXEC (@openrowset)

but if you are still using ##, you might have troubles if 2 users are running the same code at the same time because the temp table is global to all users

but then it won't work in EXEC because it won't be global!
