Return a value from EXEC

Hi everybody

How to return a value like that
I dont want to use Stored proc.
Thanks

DECLARE @.cpt as integer
DECLARE @.pTable as varchar(40)

Select @.pTable = 'Salaires'
SELECT @.cpt = EXEC('Select Count(*) FROM ' + @.pTable)

Print @.cptdeclare @.i int
declare @.sql nvarchar(1000)
select @.sql = 'Select @.i = Count(*) FROM ' + @.pTable
exec sp_executesql @.sql, N'@.i int out', @.i out
select @.i
