SQL Detach Database

Let us see the steps to detach the database in SQL Server using the existing stored procedure and Management Studio.

SQL Detach Database Approach

From the below screenshot, you can see that the SQL server has the AdventureWorks2017.

View DB in Management Studio 1

It has a sp_detach_db stored procedure to detach the database. The syntax for this is

EXEC sp_detach_db N'Database Name', 'true';

Let me use the above syntax to delete AdventureWorks 2017.

EXEC sp_detach_db N'AdventureWorks2017', 'true';
