Answer 1

    DECLARE @Country_List TABLE
(
  Name char(3) ,
  Region_name nvarchar(50),
  _Count int
)
BEGIN TRANSACTION
 INSERT INTO @Country_List (Name, Region_name,_Count)
SELECT 
CountryList.Name,CountryList.Region_name,COUNT(*)

FROM [Ips] 
INNER JOIN [BlackSeo_CountryList] ON [CountryList].ID =[Ips].Country 
GROUP BY CountryList.Name,CountryList.Region_name,[Ips].Country

ROLLBACK TRANSACTION
SELECT * FROM @Country_List


This OK
