Array对象允许在一个变量中存储多个值。它存储相同类型元素的固定大小的顺序集合。数组用于存储数据集合,但将数组看作同一类型变量的集合通常更有用。本文主要介绍JavaScript(JS) array.join(separator) 方法。 1、描述 JavaScript数组join()方法将数组的所有元素连接到字符串中。
使用INSERT INTO语句将数据插入主表和子表。我们为主表插入了三条记录,分别是id为1、2、3的记录,对应的name分别是’John’、‘Alice’和’Bob’。对于子表,我们为每个主表记录插入了一条关联记录,并为其设置了other_field。 创建索引 为了提高Array Join的查询效率,我们使用CREATE INDEX语句为主表和子表的关联...
