Insert Value In Identity Column In SQL Server

In this article, we will discuss how to insert value in the identity column in the SQL server.

"Identity_Insert" Statement

By setting "Identity_insert" as "On", we can insert value in the identity column in the SQL server.

Syntax

Set Identity_insert table_name On / Off

Example

Let us consider the below table: -

In the above table, the column "id" is an auto-increment field. Let us see, what will happen when we insert a value in the "id" column using the following command.

Insert into TestTable 
values 
  (1, 'Test1')

You will get the following error - Msg 8101, Level 16, State 1, Line 3

An explicit value for the identity column in table 'TestTable' can only be specified when a column list is used and IDENTITY_INSERT is ON

Now, let us use the "identity_insert" statement.

Set   Identity_insert TestTable On 
Insert into TestTable (id, Name) 
values 
  (1, 'Test1')
Set Identity_insert TestTable Off

Once you execute the above statements and check the table, you will see that data gets inserted into the table.
