Optional Parameters

-SqlInstance

The target SQL Server instance or instances.

Alias
Required False
Pipeline false
Default Value
-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.

Alias
Required False
Pipeline false
Default Value
-Database

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

Alias
Required False
Pipeline false
Default Value
-ExcludeDatabase

The database(s) to exclude. This list is auto-populated from the server.

Alias

-InputObject

Enables piped input from Get-DbaDatabase

Alias
Required False
Pipeline true (ByValue)
Default Value
-Path

Specifies the directory where the file or files will be exported.
Will default to Path.DbatoolsExport Configuration entry

Alias
Required False
Pipeline false
Default Value (Get-DbatoolsConfigValue -FullName 'Path.DbatoolsExport')
-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.

Alias
Required False
Pipeline false
Default Value False
-WhatIf

Shows what would happen if the command were to run. No actions are actually performed.

Alias wi
Required False
Pipeline false
