Create temp table using dynamic sql

I have a stored procedure in which I need to create a single temp table based on one of several views

Each of the views has a differing amount of fields

I will use this table to turn around and  generate a csv file

Is there a way to put the view name into a variable and use that variable value to create the temp table?

You could just select all columns into the temp table:
SELECT *
INTO #tmp_table
FROM MyView

Just to make the obvious statement, YOU ARE PLAYING WITH FIRE here as changes in columns will cause the creation of a single set to fail.

Aside from that, you can always UNION views together creating dummy columns where you need them.  Something like.
SELECT goo, foo, boo, '' as yabba, '' as dabba, '' as doo
FROM cute_names
UNION
SELECT '', '', '', yabba, dabba, doo
FROM fred_flintstone_sayings

Wait.  Is the OP asking for a dynamic way to create a temp table based on 1 view ?   That's how I read it.  If that's not the case, then please disregard my earlier answer.

Hmm .. looks like we'll need a clarification, as I interpreted it as multiple views, which after a second reading may not be correct.

It would be vastly easier to use a non-temp table, even if you create it in the tempdb db.

The difficulty with a temp table is that a temp table created in dynamic SQL would be automatically deallocated when the dynamic SQL ends, since that SQL runs as a separate batch.

But you could generate a unique name for a "real" table in tempdb -- such as using YYYYMMDD_<guid>, minus the dashes in the guid -- and use that for processing to the csv, then delete the table explicitly yourself when you're done.  That name pattern would allow you to delete "left-over" tables later as well.

Thanks for all the posts!

After rereading my question I realized I was indeed unclear

I wanted to give at least some points to all posts

Ultimately scott's suggestion is the one I went with so I give him the most
