DROP ROLE (Transact-SQL)

[!INCLUDEtsql-appliesto-ss2008-xxxx-asdw-pdw-md]

Removes a role from the database.

Transact-SQL Syntax Conventions

Syntax

-- Syntax for SQL Server  
  
DROP ROLE [ IF EXISTS ] role_name  

-- Syntax for Azure SQL Data Warehouse and Parallel Data Warehouse  
  
DROP ROLE role_name  

Arguments

IF EXISTS
Applies to: [!INCLUDEssNoVersion] ( [!INCLUDEssSQL15] through current version).

Conditionally drops the role only if it already exists.

role_name
Specifies the role to be dropped from the database.

Remarks

Roles that own securables cannot be dropped from the database. To drop a database role that owns securables, you must first transfer ownership of those securables or drop them from the database. Roles that have members cannot be dropped from the database. To drop a role that has members, you must first remove members of the role.

To remove members from a database role, use ALTER ROLE (Transact-SQL).

You cannot use DROP ROLE to drop a fixed database role.

Information about role membership can be viewed in the sys.database_role_members catalog view.

Caution

[!INCLUDEssCautionUserSchema]

To remove a server role, use DROP SERVER ROLE (Transact-SQL).

Permissions

Requires ALTER ANY ROLE permission on the database, or CONTROL permission on the role, or membership in the db_securityadmin.

Examples

The following example drops the database role purchasing from the AdventureWorks2012 database.

DROP ROLE purchasing;  
GO
