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// Bart Jourquin
9// Mark Johnson, wxWindows@mj10777.de
10// Mods: Dec, 1998:
11// -Added support for SQL statement logging and database cataloging
12// Mods: April, 1999
13// -Added QUERY_ONLY mode support to reduce default number of cursors
14// -Added additional SQL logging code
15// -Added DEBUG-ONLY tracking of wxTable objects to detect orphaned DB connections
16// -Set ODBC option to only read committed writes to the DB so all
17// databases operate the same in that respect
18// Created: 9.96
19// RCS-ID: $Id$

26// 2) All enhancements and bug fixes are to be submitted back to the wxWindows

2443 - The first one (wxDbColInf *wxDb::GetColumns(wxChar *tableName[], const

2445 before merging the results. This makes the code easier to maintain as

2449 - It doesn't anymore rely on the type-name to find out which database-type

3353 *
3354 * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE
3355 * ---------------------------------------------------
3356 *
3357 * ORACLE
3358 * - Currently the only database supported by the class to support VIEWS
3359 *
3360 * DBASE
3361 * - Does not support the SQL_TIMESTAMP structure
3362 * - Supports only one cursor and one connect (apparently? with Microsoft driver only?)
3363 * - Does not automatically create the primary index if the 'keyField' param of SetColDef
3364 * is TRUE. The user must create ALL indexes from their program.
3365 * - Table names can only be 8 characters long
3366 * - Column names can only be 10 characters long
3367 *
3368 * SYBASE (all)
3369 * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added
3370 * after every table name involved in the query/join if that tables matching record(s)
3371 * are to be locked
3372 * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above
3373 *
3374 * SYBASE (Enterprise)
3375 * - If a column is part of the Primary Key, the column cannot be NULL
3376 * - Maximum row size is somewhere in the neighborhood of 1920 bytes
3377 *
3378 * MY_SQL
3379 * - If a column is part of the Primary Key, the column cannot be NULL
3380 * - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE
3381 * - Columns that are part of primary or secondary keys must be defined as being NOT NULL
3382 * when they are created. Some code is added in ::CreateIndex to try to adjust the
3383 * column definition if it is not defined correctly, but it is experimental
3384 * - Does not support sub-queries in SQL statements
3385 *
3386 * POSTGRES
3387 * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0
3388 * - Does not support sub-queries in SQL statements
3389 *
3390 * DB2
3391 * - Primary keys must be declared as NOT NULL
3392 * - Table and index names must not be longer than 13 characters in length (technically
3393 * table names can be up to 18 characters, but the primary index is created using the
3394 * base table name plus "_PIDX", so the limit if the table has a primary index is 13.
3395 *
3396 * PERVASIVE SQL
3397 *
3398 * INTERBASE
3399 * - Columns that are part of primary keys must be defined as being NOT NULL
