Solution 1

This is trivial, you should read documentation[^] properly. BTW your tags don't say what database you are using. I assume SQL Server.

SQL

create table Example1
(
	ID1 INT PRIMARY KEY, 
	ID2 INT IDENTITY(1,1),
)

Dude He want to add identity to ID2 not ID1.

Tomas Takac 15-Dec-14 4:25am

Right, thanks for noticing. I was assuming he wants it on PK automatically.

K.Y.S.Phaneendra 15-Dec-14 4:25am

I am sorry I use SQL server only but my problem is that if I already created the table and want to make the ID2 as IDENTITY COLUMN
