The main loop then looks through its internal mapping table between its signals and handlers, also called callbacks, and calls the handlers registered for the given signal on the given object. 然后主循环查询自己的信号和处理程序之间的内部映射表,也叫做回调,并调用注册到指定对象的指定信号的处理程序。
This registry variable causes the optimizer to favor nested loop joins to join the list of values, using the table that contributes the IN list as the inner table in the join. 这个注册表变量会导致优化器优先使用嵌套循环连接来连接值列表,使用为IN列表提供值的表作为连接的内部表。
However, you will now need to explicitly loop over the database query result object to create the table rows and add the Edit option. 不过,现在需要显式地对数据库查询结果对象进行循环以便创建这些表的行并添加Edit选项。
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。
There is logic responsible for verifying which elements are actually present, and then a for loop builds a table with the available columns. 代码中包含负责验证实际存在哪些元素的逻辑,接着,for循环用实际存在的列构建一张表。
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 code is a simple loop through all posts in a hypothetical posts table, displaying the category and the body of the post. 此代码是一个简单的循环,遍历了一个假想的post表内的所有post,并显示post的类别和它的主体。
This is a lot faster than a nested loop join of two table scans without any index usage. 这比不使用任何索引的两个表扫描的嵌套循环连接要快得多。
The last call in the loop calls the report client and tells it to add your row values to the table. 循环中的最后一个调用,调用报告客户端,并告诉它将行值添加到表中。
