在 SQL Server 2014 中使用 MERGE

Question

我在 SQL 服务器中使用 MERGE 时遇到问题。

MERGE Info_Game AS t 
USING (
with cte_example 
as
(SELECT ig_idx,ig_team1,ig_team2benefit,ig_game_type
FROM (select ig_idx,ig_team1,ig_team2benefit,ig_game_type,
RANK() OVER(partition by ig_root,ig_game_type order by ig_idx asc) AS rank
FROM  info_game ) AS t1
WHERE rank < 2)

select *
       ,count(name) over(partition by name) count
from cte_example

) s ON t.ig_outcome_id = s.ig_idx 

WHEN MATCHED THEN
    UPDATE 
        SET s.IG_Team1Benefit = t.pv_v1,
            s.ig_drawbenefit = t.pv_v2,
            s.IG_Team2Benefit = t.pv_v3

WHEN NOT MATCHED THEN
    INSERT (ig_idx, ig_team1, ig_team2benefit, ig_game_type) 
    VALUES (s.ig_idx, s.ig_team1, s.ig_team2benefit, s.ig_game_type)
OUTPUT $action, Inserted.*, Deleted.*;

但我在 WITH cte_example

中遇到错误

Msg 156, Level 15

我该怎么做？

Answer 1

;with cte_example 
as
(SELECT ig_idx,ig_team1,ig_team2benefit,ig_game_type
FROM (select ig_idx,ig_team1,ig_team2benefit,ig_game_type,
RANK() OVER(partition by ig_root,ig_game_type order by ig_idx asc) AS rank
FROM  info_game ) AS t1
WHERE rank < 2)
MERGE 
Info_Game AS t 
USING (
select *
       ,count(name) over(partition by name) count
from cte_example

) s

ON t.ig_outcome_id = s.ig_idx 
WHEN MATCHED  THEN
UPDATE SET 
s.IG_Team1Benefit = t.pv_v1,
s.ig_drawbenefit = t.pv_v2,
s.IG_Team2Benefit = t.pv_v3
WHEN NOT MATCHED THEN
INSERT 
(ig_idx,ig_team1,ig_team2benefit,ig_game_type) 
VALUES 
(s.ig_idx,s.ig_team1,s.ig_team2benefit,s.ig_game_type)

Answer 2

Cte 不应在 Merge 语句内。搬出去。

;with cte_example 
as
(SELECT ig_idx,ig_team1,ig_team2benefit,ig_game_type
FROM (select ig_idx,ig_team1,ig_team2benefit,ig_game_type,
RANK() OVER(partition by ig_root,ig_game_type order by ig_idx asc) AS rank
FROM  info_game ) AS t1
WHERE rank < 2)

MERGE 
Info_Game AS t 
USING (

select *
       ,count(name) over(partition by name) count
from cte_example

) s

ON t.ig_outcome_id = s.ig_idx 
WHEN MATCHED  THEN
UPDATE SET 
s.IG_Team1Benefit = t.pv_v1,
s.ig_drawbenefit = t.pv_v2,
s.IG_Team2Benefit = t.pv_v3
WHEN NOT MATCHED THEN
INSERT 
(ig_idx,ig_team1,ig_team2benefit,ig_game_type) 
VALUES 
(s.ig_idx,s.ig_team1,s.ig_team2benefit,s.ig_game_type)
OUTPUT $action, Inserted.*, Deleted.*;
