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

3347 *
3348 * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE
3349 * ---------------------------------------------------
3350 *
3351 * ORACLE
1e92909e 3352 * - Currently the only database supported by the class to support VIEWS
a2115c88
GT		 3353 *
3354 * DBASE
1e92909e
GT		 3355 * - Does not support the SQL_TIMESTAMP structure

fdc03678 3357 * - Does not automatically create the primary index if the 'keyField' param of SetColDef
a144affe 3358 * is TRUE. The user must create ALL indexes from their program.
1e92909e
GT		 3359 * - Table names can only be 8 characters long
3360 * - Column names can only be 10 characters long
a2115c88
GT		 3361 *
3362 * SYBASE (all)
1e92909e
GT		 3363 * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added
3364 * after every table name involved in the query/join if that tables matching record(s)
3365 * are to be locked
3366 * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above
a2115c88
GT		 3367 *
3368 * SYBASE (Enterprise)
1e92909e 3369 * - If a column is part of the Primary Key, the column cannot be NULL

3376 * when they are created. Some code is added in ::CreateIndex to try to adjust the

3378 * - Does not support sub-queries in SQL statements

a8aa2258

3387 * table names can be up to 18 characters, but the primary index is created using the
