MySQL的全內加入

Question

我

SELECT clientReport.id 
FROM clientReport 
LEFT JOIN report02 ON (report02.id = clientReport.id) 
WHERE report02.id is null; 

，做的

SELECT clientReport.id 
WHERE clientReport.rowNumber NOT EXISTS (
SELECT clientReport.rowNumber FROM report02, clientReport 
WHERE report02.id=clientReport.id); 

我需要相當的，想必，一個完整的內部連接也得到錯配report02，不只是CLIENTREPORT。我如何編寫連接來執行此操作？

Answer 1

下面應該工作。

SELECT clientReport.id,report02.id 
FROM clientReport 
FULL OUTER JOIN report02 ON (report02.id = clientReport.id) 
WHERE report02.id is null 
OR clientReport.id is null; 

應該，但它不會（像MySQL目前不支持FULL OUTER JOIN。）

這是更可能的工作：

(SELECT clientReport.id AS report01 
     , report02.id  AS report02 
    FROM clientReport 
    LEFT OUTER JOIN report02 
     ON (report02.id = clientReport.id) 
    WHERE report02.id IS NULL 
) 
UNION 
(SELECT clientReport.id AS report01 
     , report02.id  AS report02 
    FROM clientReport 
    RIGHT OUTER JOIN report02 
     ON (report02.id = clientReport.id) 
    WHERE clientReport.id is null 
)
