Hi , I want to ask a question ,Is it possible executing dynamic sql and store values in a temp table with WITH clause like below code?
DECLARE @sqltxt nvarchar(max) ;
SET @sqltxt='select col112,col221 from sometable';
WITH temptable (col1,col2) as
(exec sp_executesql @sqltxt )
select * from temptable
Or how can I achive this task with sql?
Thanks.
First of all, you shouldn't hijack other peoples' threads when you can easily start a new one of your own. Secondly, I shouldn't encourage you in doing so by answering your questions. 🙂
But since I answered before realizing this, I'll say I'm pretty sure that your syntax will not work. Try it!
You could try do something like this:
DECLARE @sqltxt nvarchar(max) ;
SET @sqltxt='INSERT INTO temptable (col1,col2) select col112,col221 from sometable';
exec sp_executesql @sqltxt
select * from temptable
That will work with permanent or temporary tables, but not table variables (they will not be in the context of the executed dynamic SQL).
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
