Hi all . . .
Is it possible to return the results of a stored procedure into either a CTE or temp table?
In other words, is it possible to do this:
with someCTE as (
exec someStoredProc
)
or this:
exec someStoredProc into #tempTable
???
Thanks in advance!

INSERT INTO #tempTable

EXEC dbo.someStoredProc

The INSERT ... EXEC can be used to insert into a table variable or temp table. A CTE however, despite its name, is not a table and hence can not have anything inserted into it. Think of a CTE as a temporary view, so a select statement.

Acutally you can insert into a cte, just like you can delete from them.

create table cteInsert

(

SomeValue varchar(20)

);

with myCTE as

(

select SomeValue

from cteInsert

)

insert myCTE

select 'Inserted'

select * from cteInsert;

with myDeleteCte as

(

select SomeValue

from cteInsert

)

delete myDeleteCte

select * from cteInsert;

drop table cteInsert

In reference to the thread however it doesn't make much sense. 🙂

No, actually you can't. What you can do is insert into a table (permanent, temporary or variable) through a CTE, just as you can with a view (if it is updateable).

You're not inserting into the CTE because a CTE has no persistent storage, it's just a select statement. The insert is into the base tables that the CTE is defined upon.

True enough. I should have said that you can use them as the source for those operations but the data will really reside in the base table. Thanks for the correction.

Excellent suggestion. Also,

insert into #tab

exec (@MyDynamicCode)

But "insert into" will only insert into an existing table. What about creating a new table?

Use SELECT/INTO with OPENROWSET to call the proc. If you want to pass parameters to the proc, it's all going to have to be dynamic SQL because OPENROWSET can't take parameters.

Thanks 🙂 , but I'm trying to run some dynamic sql which I have built into a memory variable, rather than calling a stored procedure. Something like:

select *

into #tab

from exec (@MyDynamicCode)

which I know is wrong. I may not have rights to use openrowset, and anyway, using OLE DB for dealing with SQL server tables within SQL Server seems somehow inappropriate.

CREATE TABLE ...

INSERT INTO

EXEC ...

Caveat is that you have to know the structure of the result set, but to be honest if you have a procedure that's non-deterministic in terms of the result set it's returning, there's probably something deeper that needs fixing/changing

The output table is the result of a dynamic pivot, so the columns created depends on the values in the data. Yes, its non-deterministic, but fairly standard practise, is it not?

Can we insert the results of above CTE into temp table?

cmerrell Mr or Mrs. 500 Points: 522 More actions · Answer 13

You can, but you can't read the temp table after your initiating procedure regains control, the table has disappeared!
