Used to list database transaction details as they occur. The transaction log can be useful for isolating the causes of unexpected interactions between OpenBuildings Station Designer and the database. Processing slows significantly, however. Transaction details include SQL statements (generated by OpenBuildings Station Designer or an application or submitted by the user in the SQL Window), OpenBuildings Station Designer database requests, and status and error messages issued by the database software. OpenBuildings Station Designer database requests are listed in UPPERCASE.
