SQL Server Identity Seed

Question

I have a SQL Servier database where I store schedules for multiple companies in a table called tblSchedules.

The primary key for this table is ScheduleRatesID and auto increments.

Is there a way to have is increment from 700000 for Company A and 800000 for Company B?

Answer 1

您可以将它们放入两个不同的表中，然后使用视图将它们结合在一起...恐怕这是您唯一的选择。

Answer 2

我的建议是删除此表上的自动增量，并创建一个触发器来检查companyid，并且必须基于companyid计算并在指定的两个不同范围之间插入一个唯一的主键。

Answer 3

No. Identity does not work that way.

Sit down and write your own mechanism - it is not particularly hard.
