SYNTAX

Remove-DbaDbRoleMember [[-SqlInstance] <Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]>]

DESCRIPTION

The Remove-DbaDbRoleMember removes users in a database from a database role or roles for each instance(s) of SQL

Server.





PARAMETERS

-Database [<System.String[]>]

The database(s) to process. This list is auto-populated from the server. If unspecified, all databases will be

processed.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-EnableException [<Switch>]

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.

This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables

advanced scripting.

Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own

try/catch.
