我找到了一些用于MS SQL Server的遗留SQL(T-SQL),它有一个子句
1 | TableA JOIN TableB |
我只是想知道这是否与
1 | TableA INNER JOIN TableB |

或者有什么区别?
另外,如果我将它移植到另一个数据库引擎,例如mysql、access、oracle,join的含义也总是与inner join相同?
你试过了吗?
引自Palehorse:
They function the same.
INNER JOIN can be a bit more clear to read,
especially if your query has other join types (e.g. LEFT or RIGHT)
included in it.
