When specified, the user will be associated to this SQL login and have the same name as the Login.
Alias
Required True
Pipeline false
Default Value
-Password

When specified, the user will be created as a contained user. Standalone databases partial containment should be turned on to succeed. By default, in Azure SQL databases this is turned on.
Alias
Required True
Pipeline false
Default Value
-ExternalProvider

Alias

Pipeline false
Default Value

Specifies the database(s) to process. Options for this list are auto-populated from the server. If unspecified, all user databases will be processed.
Alias
Required False
Pipeline false
Default Value
-ExcludeDatabase

Specifies the database(s) to exclude from processing. Options for this list are auto-populated from the server. By default, system databases are excluded.

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

If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.
