Prior to release 11.1 of VTScada, logged tag data was stored in separate tables. These legacy tables may still be viewed if this application property SQLQueryHideLegacyTables is set to 0 (false). If set to 1 (true), only the History table (and any History:TPP tables) will be visible.
Default: SQLQueryHideLegacyTables = 0
