Understanding SQL Server User Accounts

Before we dive into the process of creating users in SQL Server, let’s first take a moment to understand what user accounts are and why they are important.

Step 3: Set Permissions for the User

Once you have created the user account, the next step is to set permissions for the user. This will determine what actions the user is allowed to perform in the database.

Using SQL Server Management Studio:

To set permissions for a user using SSMS, follow these steps:

1. Right-click on the user in the Security folder in Object Explorer.
2. Select “Properties”.
3. Click on the “Securables” tab.
4. Select the securable you want to grant permissions for.

Frequently Asked Questions

What is the difference between a Windows user account and a SQL Server login?

A Windows user account is created in the Windows operating system and is used to access the database. It can be used to authenticate both local and remote users. A SQL Server login is created within SQL Server and is used to access the database. It is typically used for remote access and cannot be used to authenticate local users.

What permissions can I grant or deny to a user?

You can grant or deny permissions to a user for a variety of actions, including SELECT, INSERT, UPDATE, DELETE, EXECUTE, and VIEW DEFINITION. You can also grant or deny permissions for specific objects, such as tables, views, stored procedures, and functions.

How do I revoke permissions from a user?

To revoke permissions from a user, follow the same steps for granting permissions, but select “Revoke” instead of “Grant”.

Can I create a user account without a login?

No, you cannot create a user account without a login. The user account is tied to a login to control access to the database.

Can I create a login without a user account?

Yes, you can create a login without a user account. This is typically used for remote access and cannot be used to authenticate local users.
