Auto increment table column

Question

Using Postgres, I\'m trying to use AUTO_INCREMENT to number my primary key automatically in SQL. However, it gives me an error.

CREATE TABLE Sta         


        

Answer 1

You do not specify which RDBMS you are using, however, in SQL Server you can use this syntax:

CREATE TABLE [dbo].[Staff]
(
[ID] [int] IDENTITY(1,1) NOT NULL,
[Name] VARCHAR(40) NOT NULL,
CONSTRAINT [ID] PRIMARY KEY CLUSTERED 
(
[ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO
