3// Purpose: Implementation of the wxDb class. The wxDb class represents a connection
4// to an ODBC data source. The wxDb class allows operations on the data
108106cf
JS
5// source such as opening and closing the data source.
6// Author: Doug Card

23f681ec 10// Mods: Dec, 1998:
a2115c88
GT
11// -Added support for SQL statement logging and database cataloging
12// Mods: April, 1999
1e92909e
GT
13// -Added QUERY_ONLY mode support to reduce default number of cursors
14// -Added additional SQL logging code
a2115c88 15// -Added DEBUG-ONLY tracking of wxTable objects to detect orphaned DB connections
1e92909e 16// -Set ODBC option to only read committed writes to the DB so all
a2115c88 17// databases operate the same in that respect
