如何在oracle中对两个表执行别名连接？

Question

我有以下问题。我有 2 个表想要加入“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

在加入之前，我想做一些类似 ALIAS 的事情，我有这样的事情：

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 中运行的正确查询是什么？我认为这是我想要的左连接？（连接后，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 ...

而不是LEFT OUTER你可以有INNER, FULL OUTER, ...; 请参阅此处了解更多信息。
