sql - 如何在oracle中为两个表执行别名连接？

Question

我有以下问题。我有 2 个表要加入“TableALong”和“TableBLong”

TableALong

ID, Name, Store,Age
1, John, Walmart, 5
2, Johnny, Walmart, 8
3, Johnny, Target , 10
4, Bill, Shoppers, 2
5, Joe, Target, 3

TableBLong
ID, Name, Store, StoreAddress
1, John, Walmart, 35353 Address
1, John, Walmart, 53544 Address
2, Johnny, Walmart, 35353 Address

我想在加入之前做一些类似 ALIAS 的事情:

SELECT A.ID, A.NAME, A.STORE, A.AGE, B.STOREADDRESS
FROM TableALong as A, TableBLong as B
ON A.NAME = B.NAME and A.STORE = B.STORE

这在oracle中是无效的。让它在 oracle 中工作的正确查询是什么？我假设这是我想要的左连接？ (join后，TableALong中的每一项都会有多行。)

Answer 1

固定查询:

SELECT A.ID,
       A.NAME,
       A.STORE,
       B.STOREADDRESS as yourAlias /* AS is ok for column aliases ... */
FROM TableALong A                  /* ... but not for table aliases */
     LEFT OUTER JOIN TableBLong  B /* JOIN syntax */
       ON (A.NAME = B.NAME and A.STORE = B.STORE)
WHERE ...

您可以使用 INNER、FULL OUTER，而不是 LEFT OUTER，...；见here了解更多。
