///////////////////////////////////////////////////////////////////////////////
// Name: db.cpp
// Purpose: Implementation of the 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
// Mods: Dec, 1998:
// -Added support for SQL statement logging and database cataloging
// Mods: April, 1999
// -Added QUERY_ONLY mode support to reduce default number of cursors
// -Added additional SQL logging code
// -Added DEBUG-ONLY tracking of wxTable 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
// RCS-ID: $Id$
// Copyright: (c) 1996 Remstar International, Inc.
// Licence: wxWindows licence, plus:
// Notice: This class library and its intellectual design are free of charge for use,
// modification, enhancement, debugging under the following conditions:
// 1) These classes may only be used as part of the implementation of a
// wxWindows-based application
// 2) All enhancements and bug fixes are to be submitted back to the wxWindows
// user groups free of all charges for use with the wxWindows library.
// 3) These classes may not be distributed as part of any other class library,
// DLL, text (written or electronic), other than a complete distribution of
// the wxWindows GUI development toolkit.

* NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE
* ---------------------------------------------------
*
* ORACLE
* - Currently the only database supported by the class to support VIEWS
*
* DBASE
* - Does not support the SQL_TIMESTAMP structure
* - Supports only one cursor and one connect (apparently? with Microsoft driver only?)
* - Does not automatically create the primary index if the 'keyField' param of SetColDef
* is TRUE. The user must create ALL indexes from their program.
* - Table names can only be 8 characters long
* - Column names can only be 10 characters long
*
* SYBASE (all)
* - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added
* after every table name involved in the query/join if that tables matching record(s)
* are to be locked
* - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above
*
* SYBASE (Enterprise)
* - If a column is part of the Primary Key, the column cannot be NULL
*
* MY_SQL
* - If a column is part of the Primary Key, the column cannot be NULL
* - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE
*
* POSTGRES
* - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0
