Synopsis

Sets database owners with a desired login if databases do not match that owner.

Description

This function will alter database ownership to match a specified login if their current owner does not match the target login. By default, the target login will be 'sa', but the function will allow the user to specify a different login for ownership. The user can also apply this to all databases or only to a select list of databases (passed as either a comma separated list or a string array).

Optional Parameters

-SqlInstance

The target SQL Server instance or instances.

-SqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
For MFA support, please use Connect-DbaInstance.

-Database

Specifies the database(s) to process. Options for this list are auto-populated from the server. If unspecified, all databases will be processed.

-ExcludeDatabase

Specifies the database(s) to exclude from processing. Options for this list are auto-populated from the server.

-InputObject

Enables piping from Get-DbaDatabase

-TargetLogin

Specifies the login that you wish check for ownership. This defaults to 'sa' or the sysadmin name if sa was renamed. This must be a valid security principal which exists on the target server.

-EnableException

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.

-WhatIf

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.

-Confirm

If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.
