存储过程遍历临时表 不是用游标

DECLARE @tempKnowledgeID NVARCHAR(50)
 DECLARE @tempID int
 DECLARE @Table TABLE(
  ID INT,
  Val NVARCHAR(120)
  )
  --增加临时表数据
  INSERT INTO @Table(ID,Val) SELECT ID,[Value] FROM dbo.Split(@KnowledgeIDS,',')
---增加订阅功能
  WHILE EXISTS(select 1 from @Table)
  begin
  SET ROWCOUNT 1
     select @tempID=ID,@tempKnowledgeID=Val from @Table
  SET ROWCOUNT 0
  delete from @Table where [ID] = @tempID
  IF EXISTS(SELECT 1 FROM tbl_KbaSubscribeKnowledge WHERE knowledgeID=@tempKnowledgeID AND  userID=@UserID)
  BEGIN
  UPDATE tbl_KbaSubscribeKnowledge  SET IsActive=@IsActive,DeSubscribeTime=GETDATE() WHERE knowledgeID=@tempKnowledgeID AND  userID=@UserID
  END
  ELSE
  BEGIN
  INSERT INTO dbo.tbl_KbaSubscribeKnowledge (
   ID,
   KnowledgeID,
