Syntax


GRANT <permission> [ ,...n ]
    TO <database_principal> [ ,...n ] [ WITH GRANT OPTION ]
    [ AS <database_principal> ]

<permission>::=
permission | ALL [ PRIVILEGES ]

<database_principal> ::=
    Database_user
  | Database_role
  | Application_role
  | Database_user_mapped_to_Windows_User
  | Database_user_mapped_to_Windows_Group
  | Database_user_mapped_to_certificate
  | Database_user_mapped_to_asymmetric_key
  | Database_user_with_no_login

Arguments

permission Specifies a permission that can be granted on a database. For a list of the permissions, see the Remarks section later in this topic.

ALL This option does not grant all possible permissions. Granting ALL is equivalent to granting the following permissions: BACKUP DATABASE, BACKUP LOG, CREATE DEFAULT, CREATE FUNCTION, CREATE PROCEDURE, CREATE RULE, CREATE TABLE, and CREATE VIEW.

PRIVILEGES Included for ANSI-92 compliance. Does not change the behavior of ALL.

WITH GRANT OPTION Indicates that the principal will also be given the ability to grant the specified permission to other principals.

AS <database_principal> Specifies a principal from which the principal executing this query derives its right to grant the permission.

Database_user Specifies a database user.

Database_role Specifies a database role.

Application_role Applies to: SQL Server 2008 (10.0.x) and later, SQL Database

Specifies an application role.

Database_user_mapped_to_Windows_User Applies to: SQL Server 2008 (10.0.x) and later

Specifies a database user mapped to a Windows user.

Database_user_mapped_to_Windows_Group Applies to: SQL Server 2008 (10.0.x) and later

Specifies a database user mapped to a Windows group.

Database_user_mapped_to_certificate Applies to: SQL Server 2008 (10.0.x) and later

Specifies a database user mapped to a certificate.

Database_user_mapped_to_asymmetric_key Applies to: SQL Server 2008 (10.0.x) and later

Specifies a database user mapped to an asymmetric key.

Database_user_with_no_login Specifies a database user with no corresponding server-level principal.

Remarks

Important

A combination of ALTER and REFERENCE permissions in some cases could allow the grantee to view data or execute unauthorized functions. For example: A user with ALTER permission on a table and REFERENCE permission on a function can create a computed column over a function and have it be executed. In this case, the user must also have SELECT permission on the computed column.

A database is a securable contained by the server that is its parent in the permissions hierarchy. The most specific and limited permissions that can be granted on a database are listed in the following table, together with the more general permissions that include them by implication.

Permissions

The grantor (or the principal specified with the AS option) must have either the permission itself with GRANT OPTION, or a higher permission that implies the permission being granted.

If you are using the AS option, the following additional requirements apply.

AS granting_principal Additional permission required
Database user IMPERSONATE permission on the user, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user mapped to a Windows login IMPERSONATE permission on the user, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user mapped to a Windows Group Membership in the Windows group, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user mapped to a certificate Membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user mapped to an asymmetric key Membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database user not mapped to any server principal IMPERSONATE permission on the user, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Database role ALTER permission on the role, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
Application role ALTER permission on the role, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.

Object owners can grant permissions on the objects they own. Principals that have CONTROL permission on a securable can grant permission on that securable.

Grantees of CONTROL SERVER permission, such as members of the sysadmin fixed server role, can grant any permission on any securable in the server.

Examples

A. Granting permission to create tables

The following example grants CREATE TABLE permission on the AdventureWorks database to user MelanieK.

USE AdventureWorks;
GRANT CREATE TABLE TO MelanieK;
GO

B. Granting SHOWPLAN permission to an application role

The following example grants SHOWPLAN permission on the AdventureWorks2022 database to application role AuditMonitor.

Applies to: SQL Server 2008 (10.0.x) and later, SQL Database

USE AdventureWorks2022;
GRANT SHOWPLAN TO AuditMonitor;
GO

C. Granting CREATE VIEW with GRANT OPTION

The following example grants CREATE VIEW permission on the AdventureWorks2022 database to user CarmineEs with the right to grant CREATE VIEW to other principals.

USE AdventureWorks2022;
GRANT CREATE VIEW TO CarmineEs WITH GRANT OPTION;
GO

D. Granting CONTROL permission to a database user

The following example grants CONTROL permission on the AdventureWorks2022 database to the database user Sarah. The user must exist in the database and the context must be set to the database.

USE AdventureWorks2022;
GRANT CONTROL ON DATABASE::AdventureWorks2022 TO Sarah;
GO
