Required Parameters

-SqlInstance

The target SQL Server instance or instances

Optional Parameters

-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 which databases to search for check constraints. Accepts wildcards and multiple database names.
Use this when you need to examine constraints on specific databases rather than all accessible databases on the instance.

-ExcludeDatabase

Excludes specific databases from the check constraint search. Accepts multiple database names.
Useful when you want to scan most databases but skip certain ones like development or temporary databases.

-ExcludeSystemTable

Excludes check constraints from system tables when searching through databases.
Use this to focus only on user-created tables and avoid system table constraints that are typically not relevant for DBA reviews.

-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.
