Removes user databases using multiple fallback methods to handle stuck or locked databases.
Removes user databases by attempting three different drop methods in sequence until one succeeds. First tries the standard KillDatabase() method, then attempts to set the database to single-user mode with rollback immediate before dropping, and finally uses the SMO Drop() method. This approach handles databases that are stuck due to active connections, replication, mirroring, or other locks that prevent normal removal. System databases are automatically excluded from removal operations.

Alias | |
Required | True |
Pipeline | false |
Default Value |
Specifies the user database(s) to remove from the SQL Server instance. Accepts multiple database names and supports wildcards for pattern matching.
Use this when you need to remove specific databases rather than all user databases. System databases (master, model, msdb, tempdb, resource) are automatically excluded and cannot be removed.
Alias | Name |
Required | True |
Pipeline | false |
Default Value |
Accepts database objects from the pipeline, typically from Get-DbaDatabase or other dbatools database commands.
Use this for pipeline operations when you want to filter databases first, then remove the filtered results. This provides more flexibility than specifying database names directly.

Required | True |
Pipeline | true (ByValue) |
Default Value |
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.

Pipeline | false |
Default Value |
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.
