// 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

//              Mark Johnson, [e-mail]
// 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
