Getting the Last Inserted Record ID from an SQL Server Table in

In this article, we will discuss how to determine the last inserted record ID from an SQL Server table using We will explore both direct methods and utilizing stored procedures to achieve this.

Introduction

When working with databases, it is often necessary to obtain the identity of the last inserted record. In SQL Server, the function SCOPE_IDENTITY is particularly useful for this purpose. This article provides a comprehensive guide on how to use SCOPE_IDENTITY both directly and via stored procedures in

Using SCOPE_IDENTITY Directly

The SCOPE_IDENTITY function returns the last identity value generated for any table in the current scope and session. Here is a step-by-step guide on how to use it:

Step 1: Insert the Record

To insert a record into an SQL Server table, you need to use the INSERT statement. After executing the insert, you can retrieve the identity of the inserted record with SCOPE_IDENTITY.

{% code %}

Imports Module Module1    Sub Main()        Dim connectionString As String  "YourConnectionString"        Dim lastInsertedId As Integer        Using connection As New SqlConnection(connectionString)            Dim command As New SqlCommand("INSERT INTO YourTable (Column1, Column2) VALUES (@Value1, @Value2);", connection)            ("@Value1", "SomeValue")            ("@Value2", "SomeOtherValue")            ' Execute the command and retrieve the last inserted ID            lastInsertedId  command.ExecuteScalar()            Console.WriteLine(lastInsertedId)        End Using    End SubEnd Module

{% endcode %}

Explanation

Connection String: Replace YourConnectionString with your actual database connection string. SqlCommand: The INSERT statement includes OUTPUT, which retrieves the ID of the newly inserted record. Parameters: Use AddWithValue to safely add parameters to your command to prevent SQL injection. ExecuteScalar: This method executes the command and returns the first column of the first row in the result set, which is the last inserted ID in this case. Output: Finally, the ID is printed to the console.

Note that your table should have an identity column, typically used as the primary key.

Using Stored Procedures

For a more structured approach, you can use stored procedures to handle both the insertion and retrieval of the last inserted ID. Here’s how to achieve this:

Step 1: Create a Stored Procedure

Create a stored procedure in SQL Server that includes the SCOPE_IDENTITY function at the end. For example:

{% code %}

CREATE PROCEDURE InsertAndReturnId    @Value1 nvarchar(50),    @Value2 nvarchar(50)ASBEGIN    INSERT INTO YourTable (Column1, Column2)    VALUES (@Value1, @Value2)    SELECT SCOPE_IDENTITY() As MyLast_IDEND

{% endcode %}

Step 2: Call the Stored Procedure in

Instead of directly applying the INSERT statement, call the stored procedure and retrieve the last inserted ID:

{% code %}

Imports Module Module1    Sub Main()        Dim connectionString As String  "YourConnectionString"        Dim lastInsertedId As Integer        Using connection As New SqlConnection(connectionString)            Dim command As New SqlCommand("InsertAndReturnId", connection)                          ("@Value1", "SomeValue")            ("@Value2", "SomeOtherValue")            ' Execute the command and retrieve the last inserted ID            lastInsertedId  command.ExecuteScalar()            Console.WriteLine(lastInsertedId)        End Using    End SubEnd Module

{% endcode %}

Conclusion

By leveraging SCOPE_IDENTITY and stored procedures, you can easily retrieve the last inserted record ID in This method is both efficient and secure, ensuring that your applications handle database operations with minimal errors.
