2// Name: db.cpp
f6bcfd97
BP		 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
67e9aaa3 7// Modified by: George Tasker
3ca6a5f0 8// Bart Jourquin
0cd121f9 9// Mark Johnson, wxWindows@mj10777.de
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

3388 * ---------------------------------------------------
3389 *
3390 * ORACLE
1e92909e 3391 * - Currently the only database supported by the class to support VIEWS
a2115c88
GT		 3392 *

a144affe 3397 * is TRUE. The user must create ALL indexes from their program.
1e92909e
GT		 3398 * - Table names can only be 8 characters long
3399 * - Column names can only be 10 characters long
a2115c88
GT		 3400 *
3401 * SYBASE (all)
1e92909e
GT		 3402 * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added
3403 * after every table name involved in the query/join if that tables matching record(s)
3404 * are to be locked
3405 * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above
a2115c88

1e92909e 3408 * - If a column is part of the Primary Key, the column cannot be NULL
