                  问题描述

                  我需要与一个表/结果集/任何具有整数 nm 的连接进行连接.有没有一种简单的方法可以在不构建表格的情况下获得它?

                  I need to do a join with a table/result-set/whatever that has the integers n to m inclusive. Is there a trivial way to get that without just building the table?

                  (顺便说一句,这种类型的构造会被称为什么,元查询"?)

                  (BTW what would that type of construct be called, a "Meta query"?)

                  m-n 被限制在合理范围内(<1000's)

                  m-n is bounded to something reasonable ( < 1000's)

                  推荐答案

                  没有序列号生成器 (CREATE SEQUENCE) 在 MySQL 中.最接近的是AUTO_INCREMENT,它可以帮助您构建表格.

                  There is no sequence number generator (CREATE SEQUENCE) in MySQL. Closest thing is AUTO_INCREMENT, which can help you construct the table.
