Since these roles constitute a database-level principal, they require guest– level permissions to access other databases. You can activate application roles by using the password-protected sp_setapprole command. To distinguish them from regular database roles, they are inactive by default and have no members. This allows all users, connected through a pre-specified application, to access specific data in a database. Read our guide to SQL Server row level security (coming soon) Application RolesĪpplication roles facilitate applications to run with dedicated user-like permissions. In addition to database-level roles, SQL Server also enables defining permissions at the row level.
db_ddladmin-can run data definition language (DDL) commands.db_backupoperator-can perform database backups.

db_accessadmin-can add/remove database access for Windows groups and logins, as well as SQL Server logins.Monitor this role closely as it has the ability to escalate privileges. db_securityadmin-can modify custom role memberships and manage permissions.db_owner-allowed to perform all maintenance and configuration activities on the database, as well as dropping the database.Microsoft SQL Server provides the following fixed database roles: The db-owner server role is allowed to manage membership of fixed database roles. Like server-level roles, there are fixed database-level roles built into SQL Server, and you can create additional roles, customizing them using the GRANT, DENY, and REVOKE statements.įixed roles exist independently for each database within your SQL Server instance. You can use the ALTER ROLE statement to add and remove users to database roles. SQL server defines roles that enable management of database-wide permissions. sysadmin-can perform all server activities.serveradmin-can alter server configuration and shut it down.securityadmin-can administer logins, can reset SQL server login passwords, and grant, deny or revoke server-level permissions or database-level permissions.processadmin-can end running processes in the SQL server instance.setupadmin-can add/remove linked servers and run Transact-SQL.dbcreator-can alter, create, drop, or restore databases.You cannot revoke public permission from any server role. Only assign public permissions to objects that can be made available to all users. public-default role for server principals who do not have specific securable object permissions.SQL Server provides the following fixed server roles, starting with least privileged roles: Fixed server roles allow members to add other users to the same role, but this is not so for user-defined server roles.
You can also assign server-level principals (Windows groups and accounts, and SQL server logins) to these roles. SQL Server provides several built in server roles, but you should add your own specific roles if possible. Server-level roles help manage permissions for the entire SQL Server instance. SQL Server provides three types of roles you can use to restrict access to data in your database: server-level roles, database-level roles, and application-level roles.
