Identity column in sql server

/* To explicitly supply a value for identity column*/
/*first turn on identity_insert  set  identity_insert (Table_Name) on*/
SET IDENTITY_INSERT (Table_Name) ON

/*In the insert query specify the column's list insert into table*/
INSERT INTO (Table_Name) (Identity_Column,col2,col3,...) VALUES (Identity_Value,val2,val3,...)

SET IDENTITY_INSERT (Table_Name) OFF

Identity syntax in sql

IDENTITY[(seed,increment)]
--seed is the value of the first row loaded into the table
--increment is the incremental value added to the identity value of the previous row.
--should only contain ONE identity PER TABLE

--example:
CREATE TABLE EMPLOYEE  
(  
   IID INT IDENTITY(1,1),  
   NAME [varchar](MAX) NOT NULL,  
   AGE INT NOT NULL  
)
