如何插入具有特定主键标识的表(1,1)

Question

像表一样,我们总是喜欢将identity作为主键,如identity(1,1).这样,当添加新行时,该列将以1增量1开始.

那么我可以问我是否可以手动添加一行指定的数字,就像我可以添加一行主键100

Answer 1

set Identity_Insert yourtable on

然后插入

insert yourtable (id, field) values(100,'hello')

然后再将其关闭

set Identity_Insert yourtable off

Answer 2

是的你可以.使用SET IDENTITY_INSERT [ database. [ owner. ] ] { table } { ON | OFF }:

SET IDENTITY_INSERT YourTable ON

INSERT YourTable(Id, OtherField)
VALUES (100, 'Other Value')

SET IDENTITY_INSERT YourTable OFF
