Known limitations of this version:
- Only Microsoft-supported versions of SQL Server. Sorry, 2005 and 2000.
- Outputting to table is only supported with SQL Server 2012 and higher.
- If @OutputDatabaseName and @OutputSchemaName are populated, the database and
schema must already exist. We will not create them, only the table.
