As a DBA working with SQL server and managing SQL Server environments, I have created tons of users in SQL server. It is crucial to know how to do this task smoothly. In this article, I will walk you through the simplest approaches I used to follow to create SQL server user.
How To Create A User In SQL Server
Before starting, let me clarify that you can create 2 types of uses.
- SQL Server Authentication Users: Authenticated by SQL Server.
- Windows Authentication Users: Authenticated by Windows before SQL server.
Approach-1: Creating a SQL Server Authentication Users
Follow the below steps.
1. The first step is to create a login for our SQL Server instance using the SQL query below.
USE master;
GO
CREATE LOGIN rajusa WITH PASSWORD = 'Raj@123';The query was executed successfully, as shown in the screenshot below.
2. The next step is to create a user in that database that maps to this login using the below query.
USE Test;
GO
CREATE USER rajusa FOR LOGIN rajusa;The command was executed successfully, as shown below.
So, in the above example, we created a rajusa user.
It is very important to cross-check whether the user was created successfully. Let’s execute the query below to check that.
USE Test;
GO
SELECT name, type, type_desc FROM sys.database_principals WHERE name = 'rajusa';After executing the above query, you can see that the user created successfully. Check out the screenshot below for your reference.
