-// Name: src/common/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
-// Bart Jourquin
-// Mark Johnson, wxWindows@mj10777.de
-// 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: $Id$

- * ---------------------------------------------------
- *
- * 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
- * - Maximum row size is somewhere in the neighborhood of 1920 bytes
- *
- * 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
- * - Columns that are part of primary or secondary keys must be defined as being NOT NULL
- * when they are created. Some code is added in ::CreateIndex to try to adjust the
- * column definition if it is not defined correctly, but it is experimental
- * - Does not support sub-queries in SQL statements
- *
- * POSTGRES
- * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0
- * - Does not support sub-queries in SQL statements
- *
- * DB2
- * - Primary keys must be declared as NOT NULL
- * - Table and index names must not be longer than 13 characters in length (technically
- * table names can be up to 18 characters, but the primary index is created using the
- * base table name plus "_PIDX", so the limit if the table has a primary index is 13.
- *
- * PERVASIVE SQL
- *
- * INTERBASE
- * - Columns that are part of primary keys must be defined as being NOT NULL
- * when they are created. Some code is added in ::CreateIndex to try to adjust the
- * column definition if it is not defined correctly, but it is experimental
