-// Name: wx/db.h
-// Purpose: Header file wxDb class. The wxDb class represents a connection
-// to an ODBC data source. The wxDb class allows operations on the data
-// source such as opening and closing the data source.
-// Author: Doug Card
-// Modified by: George Tasker
-// Bart Jourquin
-// Mark Johnson, wxWindows@mj10777.de
-// Mods: Dec, 1998:
-// -Added support for SQL statement logging and database cataloging
-// April, 1999
-// -Added QUERY_ONLY mode support to reduce default number of cursors
-// -Added additional SQL logging code
-// -Added DEBUG-ONLY tracking of Ctable objects to detect orphaned DB connections
-// -Set ODBC option to only read committed writes to the DB so all
-// databases operate the same in that respect
-//
-// Created: 9.96
