尽管表中有很多记录，但SQL Server游标未循环

虽然SELECT id, also FROM names WHERE isnull(also,'')<>''1返回的结果超过2000，但是以下游标未循环，但我得到了：

@count = 0

码：

DECLARE @id BIGINT, @name NVARCHAR(1000)

DECLARE @aslo TABLE (id INT, name NVARCHAR(100))

DECLARE name_cur CURSOR FOR 
     (SELECT id, also 
      FROM names 
      WHERE ISNULL(also, '') <> '')

DECLARE @count INT = 0

OPEN name_cur

WHILE @@FETCH_STATUS = 0  
BEGIN  
   SET @count = @count + 1

   INSERT INTO @aslo (id, name)
       SELECT @id, * 
       FROM string_split(@name, ',')

   FETCH NEXT FROM name_cur INTO @id, @name;  
END  

CLOSE name_cur;  
DEALLOCATE name_cur;

SELECT @count
SELECT COUNT(*) FROM @aslo a
