SQL @@IDENTITY

The SQL @@IDENTITY is a SQL System Function that returns the last inserted identity value. You can use this @@IDENTITY after an INSERT, INSERT INTO SELECT, BULK INSERT, or SELECT INTO Statement is completed to find the lastly generated identity value. And, if there is no insert operation happened then it will return NULL. In this article we will show you, How to write use this @@IDENTITY in SQL Query to extract identity value with example. For this we are going to use the below shown table data.

We are creating following table to insert the data into it.

SQL CODE

SQL @@IDENTITY Example 1

In this example first, we will insert four random records into the Employee Duplicates table. Next, we will extract the last inserted identity value using the @@IDENTITY

Let me insert value into the table using the INSERT Statement.
