Oracle和SQL Server选择（+），相当于

Question

在Oracle中，我有：

SELECT t2.Regkood, t2.naitatel, t2.naitafaks, t3.lahtiolekuaeg, t1.* 
FROM table1 t1, table2 t2, table3 t3 
WHERE t1.client = t2.client AND t1.client = t3.client(+) AND t1.client = 414246 

如何得到相同的SQL Server？

感谢

Answer 1

SELECT t2.Regkood, 
     t2.naitatel, 
     t2.naitafaks, 
     t3.lahtiolekuaeg, 
     t1.* 
FROM table1 t1 
     INNER JOIN table2 t2 
       ON t1.client = t2.client 
     LEFT JOIN table3 t3 
       ON t1.client = t3.client 
WHERE t1.client = 414246 

一些样本，以了解加入：

LEFT OUTER JOIN在ORACLE

SELECT * 
FROM A, B 
WHERE A.column = B.column(+) 

RIGHT OUTER JOIN在Oracle

SELECT * 
FROM A, B 
WHERE B.column(+) = A.column
