In general, a nested loop join with sort composite is favored by the optimizer if the inner index is well-clustered and the inner table is expected to be probed many times.
一般来说,如果内部索引是良好的集群且预测内部表被多次探测,则使用复合排序的嵌套循环联将受到优化器的青睐。
However, the benefit of the merge scan join is that the inner table does not have to be scanned repeatedly as it does for nested loop joins.
然而,合并扫描联接的好处是不必反复地扫描内部表因为其为嵌套循环联接工作。
Line 32 USES the "XSL: for-each" element to define the loop that creates the main part of the table, generating one line for each "emp" element occurrence.

Because of how nested loop joins work, the second leg (there are four nodes) is executed per outer table record.
因为嵌套循环联接的工作方式,所以每隔一个外部表记录执行第二步(共4个节点)。
This example USES two for loops. The outer for loop takes care of each row in The Times table, and the nested for loop takes care of the columns within each row.
本例使用两个for循环,外面的for循环关注乘法表中的每一行,嵌套的for循环关注每行内的列。
