Result of a dynamic select into a variable in SQL Server 2005

I need to build a select (all that in a stored procedure) based on several conditions passed to the procedure
The select should return the result in a local variable
Something like this

declare @Q varchar(1000)
declare @R integer
select @Q = 'select @R = count(*) from Lots' -- @R is an output argument
exec (@Q)


This fails (@R must be declared) on the exec
Is there another way not being simply this : select @R = count(*) from Lots'

(I need this @Q because it is being build at several places

Found this:
stackoverflow.com/questions/14399020/storing-value-in-variable-using-dynamic-sql-in-sql-server

Tested it on my test server and it seems to work just fine.

Good luck, hope that's helpful.

Try this one

declare @Q nvarchar(1000)
declare @R integer
select @Q = N'select @R = count(*) from Lots' -- @R is an output argument 
exec sp_executesql @Q,N'@R integer OUTPUT', @R OUTPUT
print @R

sjwales - Just so you know, EE is cracking down on what it refers to as 'blind links' essentially a link to a competing site with no context other than 'go here'.  To avoid any conflicts, please add a little color commentary when giving an 'go here' answer.  TIA.

jimhorn - thanks for the heads up.  Did a bit of a search in the Community Support area on this stance and have seen the why's and wherefore's behind the stance and it's understandable.

sachinpatil10d's answer does the same thing though, so the OP has his answer if mine gets deleted by admin.

Yep.  The 'add color to the link' is kind of the happy medium they came up with.   Also, this applies only to competitors sites which have a higher chance of going bad (or being a big pile of goo).  Manufacturers sites such as TechNet are considered okay.
