• Nested loop join (NLJOIN) with sort composite.

    使用复合排序的嵌套循环联接(NLJOIN)。

    youdao

  • Therefore, a total of eight records will be produced by the NLJOIN node.

    因此,总共8条记录将通过NLJOIN节点产生。

    youdao

  • This type of access path is referred to as a nested loop join (NLJOIN) with sort composite.

    这种类型的访问路径被称为使用复合排序的嵌套循环联接(NLJOIN)。

    youdao

  • There is a nested loop join (NLJOIN, step 4) of the insert (step 5) to an index scan (IXSCAN, step 7).

    其中有一个insert(步骤5)与索引扫描(步骤7)之间的嵌套循环连接(NLJOIN,步骤4 )。

    youdao

  • The NLJOIN node will eventually produce eight joined records as the output (output Cardinality value is 8).

    NLJOIN节点将最终产生8条已联接的记录作为输出(输出基数值是8)。

    youdao

  • Although IXSCAN (15) is a base access, it is dependent on NLJOIN (5), and so it can be ignored in the interim.

    尽管IXSCAN(15)是基本访问,但是它依赖于NLJOIN(5),所以可以忽略它。

    youdao

  • Relational guidelines such as join, MSJOIN, NLJOIN, and HSJOIN can be used to specify the join order and the join type.

    关系准则,比如join、MSJOIN、NLJOIN和HSJOIN都可以用来指定连接顺序和连接类型。

    youdao

  • Similarly, the last leg in the access path graph is evaluated eight times, once for each record produced by the first NLJOIN node.

    同样,访问路径图的最后一步要评估8次,通过第一个NLJOIN节点产生的每条记录都要评估一次。

    youdao

  • 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。

    youdao

  • In the previous section you learned about one type of access method, index scan (IXSCAN), and one type of join method, nested loop join (NLJOIN).

    在之前的部分您已经了解了一种类型的访问方法,即索引扫描(IXSCAN),和一种类型的联接方法,即嵌套循环联接(NLJOIN)。

    youdao

  • TBSCAN (4) — Since this is the same join predicate being resolved at NLJOIN (2), and there are no additional local predicates, we can ignore this operator.

    TBSCAN(4)——因为这个连接断言和NLJOIN(2)分析出的相同,并且没有其他局部断言,可以忽略该操作。
