How do I auto increment the primary key in a Microsoft SQL Server Management Studio database table, the datatype is declared as uniqueidentifier

Question

如何在Microsoft SQL Server Management Studio数据库表中自动增加主键，数据类型声明为uniqueidentifier，我无法将其更改为int以使用身份规范，也无法更改表，因为它已连接到其他表外键，我已经浏览了论坛，但看不到如何。

Answer 1

You cannot 'increment' a UniqueIdentifier. Instead you can generate new value by

DECLARE @GUID uniqueidentifier
SET @GUID = NEWID()

Use the value in @GUID variable everytime insert is done.

INSERT INTO tableName(primaryKeyColumn,otherColumn1,otherColumn2)
VALUES(@GUID,val1,val2)

See this article IDENTITY vs UNIQUEIDENTIFIER
