Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW)

Removes a security account from a SQL Server role in the current database.

This feature will be removed in a future version of SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Use ALTER ROLE instead.

Transact-SQL syntax conventions

Syntax

Syntax for SQL Server and Azure SQL Edge.

sp_droprolemember
    [ @rolename = ] N'rolename'
    , [ @membername = ] N'membername'
[ ; ]

Syntax for Azure Synapse Analytics and Analytics Platform System (PDW).

sp_droprolemember N'rolename' , 'membername'
[ ; ]

Note

This syntax is not supported by serverless SQL pool in Azure Synapse Analytics.

Arguments

[ @rolename = ] N'rolename'

The name of the role from which the member is being removed. @rolename is sysname, with no default. @rolename must exist in the current database.

[ @membername = ] N'membername'

The name of the security account being removed from the role. @membername is sysname, with no default. @membername can be a database user, another database role, a Windows account, or a Windows group. @membername must exist in the current database.

Return code values

0 (success) or 1 (failure).

Remarks

sp_droprolemember removes a member from a database role by deleting a row from the sysmembers table. When a member is removed from a role, the member loses any permissions it has by membership in that role.

To remove a user from a fixed server role, use sp_dropsrvrolemember. Users can't be removed from the public role, and dbo can't be removed from any role.

Use sp_helpuser to see the members of a SQL Server role, and use ALTER ROLE to add a member to a role.

Permissions

Requires ALTER permission on the role.

Examples

The following example removes the user JonB from the role Sales.

EXEC sp_droprolemember 'Sales', 'Jonb';

Examples: Azure Synapse Analytics and Analytics Platform System (PDW)

The following example removes the user JonB from the role Sales.

EXEC sp_droprolemember 'Sales', 'JonB'
