Having mentioned possible collisions between the outer and the inner legs of a join, it should also be mentioned that a similar problem could occur between the function and the INSERT operation.
提到连接的内表和外表之间各种可能的冲突之后,还应该提到的是,在这个函数与INSERT操作之间也可能发生类似的问题。
As such, the NLJOIN does not act as a classical join with two input legs, but facilitates access to the XML data for the XSCAN operator.
同样地,NLJOIN并没有充当拥有两个输入的标准连接,而是协助XSCAN操作符来访问XML数据。
Join operators such as HASH, MERGE SCAN and (in some situations) NESTED LOOP can also benefit from asynchrony by simultaneously executing the inner and outer legs of the join operator.
MERGE SCAN等连接操作符和(在某些情况下)NESTED LOOP也可以通过同时执行连接操作符的内分支和外分支而从异步中获益。
