是否有一个SQL函数可以生成给定范围的序号? [英] Is there an SQL function which generates a given range of sequential numbers?

问题描述

我需要生成一个具有给定范围的连续整数数组，以便在以下环境中使用它:

I need to generate an array of sequential integers with a given range in order to use it in:

SELECT tbl.pk_id
  FROM tbl
 WHERE tbl.pk_id NOT IN (sequential array);

推荐答案

因为您说您已经有一个数字表，所以我建议这样做:

Because you say you've already got a number table, I would suggest this:

SELECT element
FROM series
WHERE element NOT IN (SELECT pk_id
                      FROM tbl)

可能比您尝试过的查询更有效.

Might possibly be more efficient than the query you've tried.
