最常用的连接方法就是嵌套循环连接、分类合并连接和动态哈希连接。
However, if 0 is used in the predicate, a nested-loop join would be the optimal choice instead of merge join.
然而，如果断言中使用的值为0，那么内嵌循环联接可能是最优选择，而不是合并联接。
If you are using the RBO, then a merge join is the most efficient join when a join returns a large number or rows.

FETCH(3)的结果集是根据ID字段排序的，并且使用T1的索引I1的合并联接而得到最终的结果集。
Join plan directives that force optimizer to use the designated join method to join tables in the query, either nested loop join, sort merge join, or dynamic hash join.
连接计划指示，强制优化器使用指定的连接方法来连接查询中的表，要么是嵌套循环连接、分类合并连接，要么是动态哈希连接。
Typically, the optimizer chooses merge scan join when the cardinality of the outer input is not obviously small and there is no efficient access method for the inner table.
通常情况下，在外部输入的基数显然不小且对于内部表没有一种有效的访问方法时，优化器会选择合并扫描联接。
As previously stated, ordered input is essential to a merge scan join, but it is not required for nested loop joins.
如前所述，按顺序的输入对于合并扫描联接是必不可少的，但其无需嵌套循环联接。
BPMN does not provide any separate modeling elements to join or merge several branches in a process model.
BPMN并不提供任何单独的建模元素来联接或合并流程模型中的多个分支。
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.
MERGESCAN等连接操作符和(在某些情况下)NESTEDLOOP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。
What this did is it allowed banks to offer insurance or to ally and join in and merge with insurance companies.

But rather than closing, schools, particularly small ones, are likely to join forces. Some may merge, others sell themselves to a chain, either private or charitable.
有些学校，尤其是规模较小的学校愿意联合起来以避免关门，如有些选择合并，有些选择把自己卖给连锁的私立或慈善学校收购。
As shown in the IXSCAN descriptor in Figure 8, the leading column of the index exploited by optimizer is PRODUCT_NUMBER, which does not provide the order required for merge scan join.
如图8的IXSCAN描述符所示，通过优化器利用的索引的领先列是PRODUCT _ NUMBER，其不为合并扫描联接提供所需的顺序。
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。
When using WebSphere DataStage to join and merge data, it is the developer's responsibility to determine the optimal strategy based on his or her knowledge of the data.
当使用WebSphereDataStage连接和合并数据时，就要由开发人员根据对数据的认识来确定最佳策略。
If the query includes a join, the optimizer must determine the join plan (hash, sort merge, or nested loop), and the order in which tables are evaluated or joined.
如果该查询包含了连接，那么优化器就必须确定连接计划(hash、sortmerge或nestedloop)，以及评估或连接表的次序。
In SQL terms, this merge calls for an outer join, which matches each row in the work items data set to the single row in the states data set with a matching state ID.
在sql术语中，该合并会调用一个外层联系，它会将工作项数据集合中的每一行，与状态数据集合中的单个行使用匹配状态ID来匹配起来。
For the merge scan join to perform properly, both inputs are expected to be in the order of join columns.
为了合并扫描联接正确地执行，按照联接列的顺序预计有两个输入。
So when compared to a nested loop join, the merge scan join may incur the cost for sorting the inputs.
因此，当与嵌套循环联接比较时，合并扫描联接可能对于排序输入产生成本。
A merge scan join always involves one or more Equal join predicates.
一个合并联接总是涉及一个或多个Equal联接谓词。
The join behaves more like a merge on data flow models, so a lack of synchronization can occur, unless the modeler intended multiple execution of the process fragment following the join.
join的做法更像是对数据流模型进行合并，所以可能有缺乏同步的现象出现，不过如果modeler有意按join多次执行流程片段，那就另当别论了。
However, such a solution should be used with care in models that contain both types of branching, i.e., forks and decisions, to avoid suddenly closing a fork with a merge or a decision with a join.
但是，在同时包含两类分支(即fork和decision)的模型中，使用此类解决方案应十分谨慎，以避免在不经意间用一个join关闭一个fork或用一个merge关闭一个decision。
Decision and merge are always mapped to several input and output criteria-one for each branch, while fork and join correspond to a single output and input criterion, respectively.
Decision和merge始终映射到多个输入和输出条件，每个分支对应一个条件，而fork和join则分别对应于一个输出和输入条件。
Merge scan join (MSJOIN) with sort for outer and inner
使用内部和外部排序的合并扫描联接 (MSJOIN)
It also USES a merge and a join to capture the event logic.
它还使用了一个merge和一个join来捕获事件逻辑。
The TaskBarrier class mentioned above was used by the fork/join framework to manage the boundaries between the various tasks, and merge their results; in other words: to join the tasks.
前面提到的TaskBarrier类被fork/join框架用来管理不同任务的边界，并合并运行结果，换句话说就是连接任务。
This often leads to dangling inputs in a join or merge, which cause a deadlock.
这往往会导致join或merge中出现悬空输入，并进而导致死锁。
