CTE is useless and complicated!

The same result is reachable in a standard way:

create table #a (i int)

insert #a SELECT object_id FROM sys.objects

delete from t

from (SELECT * FROM #a WHERE i...

+0.5

Never used a CTE at all.

While using SELECT it will give the output in a commented lines while using EXEC it gives the error :crazy:

declare @var Varchar(1000)

set @var = '-- /* select ''Samith'' name

No, the scope is to the end of the batch, here, you can reference @j-2 out of the loop.

declare @i int

set @i = 2

while @i <...

In the following batch @j-2 is declared once, but initialized at every loop:

declare @i int

set @i = 2

while @i < 10

begin

The question itself is great, however the explanation is lacking.

There's no reference, and the explanation itself is incorrect.

There's no variable that is "reset".

The DECLARE is not ignored, it...

The scope of "set language" and "set datefirst" is per session and also per procedure/function

Try this:

create procedure proc_datefirst

as

set language 'us_english'

select @@DATEFIRST

go

set language 'Italian'

exec proc_datefirst

select @@DATEFIRST

Clear and easy question!

Thanks:-)

Thanks!

Clear qotd!

A version of the query without the use of local table:

SELECT *

FROM (

VALUES ('Steve')

, ('Stephan')

, ('Stephanie')

...

The correct exceution of the query depends on ansi_warnings

set ansi_warnings off

DECLARE @i TABLE( mychar VARCHAR(10));

INSERT @i VALUES ('Steve'), ('Stephan'), ('Stephanie')

...

Unusual altering a disabled trigger, but it's good to know!
