I have a view vwData, which has 10 base tables that make up the view.
How can I create a table from the view, keeping the structure of the view

create table newtable
from
(select * from dbo.vwData )

Something like this:
SELECT *
INTO newtable
FROM  dbo.vwData 

Open in new window


Though why you would want to do that escapes me.

>How can I create a table from the view, keeping the structure of the view
Three thoughts:
1    Anthony said the first one.
2    You do realize that the new table data will be correct only as of when the SELECT .. INTO is executed, so that if any of the 10ish table data changes, the new table is out of synch?

>keeping the structure of the view
3    You may want to explicitly state data types in the SELECT part of the query, to ensure that the data types are as you wish them to be.

If you just want a table that has the exact same schema as your view, you'd execute something similar to what Anthony suggested, but with a TOP 0 so you don't insert any actual data:

SELECT TOP 0 *
  INTO YourNewTable
  FROM YourView

That would give you a table with the same layout, but containing no rows.

I'm not sure what problem you're trying to solve, but if it's performance, here's another alternative - if all the tables that make up the view are in the same database as the view, you can actually add indexes on it that are automatically kept current - this would speed up SELECT statements based on the view, and if it's especially complicated, could improve overall performance dramatically (at the cost of slowing down DML for the underlying tables as the view will also have to be updated). To do that, you alter the view to be WITH SCHEMABINDING, then you create a clustered index on the view (this lays the data down on disk), and then you can create any supporting indexes you'd like. Again, not sure what your after, but this is an option if it's performance.

If we're missing your goal, please provide some more details about what you're trying to accomplish and we can give additional guidance.

Sorry I need to create a real table not a temporary table, the following just creates a temp table

SELECT *
INTO newtable
FROM  dbo.vwData

Define 'real'.  This will create a new physical table.  Temp tables are prefixed with pound signs ( # )

The T-SQL provided in your comment above will create a persistent table - a "real" table, as you're calling it. As Jim mentions, a temp table is one that is prefaced by # or ##, and is definitely not the case with the code we've both provided.

I get the impression your problem isn't being clearly stated - what are you trying to accomplish? It sounds like the approach might need some adjustment if what we're suggesting isn't meeting your needs.

I think you need an indexed view, as ryan indirectly stated.

There are a lot of restrictions, but if your existing view follows them all, then an indexed view will give you a searchable view that is always up-to-date.
