1. implemented wxRegKey::Copy() and CopyValue()
[wxWidgets.git] / src / common / db.cpp
1 ///////////////////////////////////////////////////////////////////////////////
2 // Name: db.cpp
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
5 // source such as opening and closing the data source.
6 // Author: Doug Card
7 // Modified by: George Tasker
8 // Mods: Dec, 1998:
9 // -Added support for SQL statement logging and database cataloging
10 // Mods: April, 1999
11 // -Added QUERY_ONLY mode support to reduce default number of cursors
12 // -Added additional SQL logging code
13 // -Added DEBUG-ONLY tracking of wxTable objects to detect orphaned DB connections
14 // -Set ODBC option to only read committed writes to the DB so all
15 // databases operate the same in that respect
16 // Created: 9.96
17 // RCS-ID: $Id$
18 // Copyright: (c) 1996 Remstar International, Inc.
19 // Licence: wxWindows licence, plus:
20 // Notice: This class library and its intellectual design are free of charge for use,
21 // modification, enhancement, debugging under the following conditions:
22 // 1) These classes may only be used as part of the implementation of a
23 // wxWindows-based application
24 // 2) All enhancements and bug fixes are to be submitted back to the wxWindows
25 // user groups free of all charges for use with the wxWindows library.
26 // 3) These classes may not be distributed as part of any other class library,
27 // DLL, text (written or electronic), other than a complete distribution of
28 // the wxWindows GUI development toolkit.
