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: $Id$
20 // Copyright: (c) 1996 Remstar International, Inc.
21 // Licence: wxWindows licence, plus:
22 // Notice: This class library and its intellectual design are free of charge for use,
23 // modification, enhancement, debugging under the following conditions:
24 // 1) These classes may only be used as part of the implementation of a
25 // wxWindows-based application
26 // 2) All enhancements and bug fixes are to be submitted back to the wxWindows
27 // user groups free of all charges for use with the wxWindows library.
28 // 3) These classes may not be distributed as part of any other class library,
29 // DLL, text (written or electronic), other than a complete distribution of
30 // the wxWindows GUI development toolkit.

3389 * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE
3390 * ---------------------------------------------------
3391 *
3392 * ORACLE
3393 * - Currently the only database supported by the class to support VIEWS
3394 *
3395 * DBASE
3396 * - Does not support the SQL_TIMESTAMP structure
3397 * - Supports only one cursor and one connect (apparently? with Microsoft driver only?)
3398 * - Does not automatically create the primary index if the 'keyField' param of SetColDef
3399 * is TRUE. The user must create ALL indexes from their program.
3400 * - Table names can only be 8 characters long
3401 * - Column names can only be 10 characters long
3402 *
3403 * SYBASE (all)
3404 * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added
3405 * after every table name involved in the query/join if that tables matching record(s)
3406 * are to be locked
3407 * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above
3408 *
3409 * SYBASE (Enterprise)
3410 * - If a column is part of the Primary Key, the column cannot be NULL
3411 * - Maximum row size is somewhere in the neighborhood of 1920 bytes
3412 *
3413 * MY_SQL
3414 * - If a column is part of the Primary Key, the column cannot be NULL
3415 * - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE
3416 * - Columns that are part of primary or secondary keys must be defined as being NOT NULL
3417 * when they are created. Some code is added in ::CreateIndex to try to adjust the
3418 * column definition if it is not defined correctly, but it is experimental
3419 * - Does not support sub-queries in SQL statements
3420 *
3421 * POSTGRES
3422 * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0
3423 * - Does not support sub-queries in SQL statements
3424 *
3425 * DB2
3426 * - Primary keys must be declared as NOT NULL
3427 * - Table and index names must not be longer than 13 characters in length (technically
3428 * table names can be up to 18 characters, but the primary index is created using the
3429 * base table name plus "_PIDX", so the limit if the table has a primary index is 13.
3430 *
3431 * PERVASIVE SQL
3432 *
3433 * INTERBASE
3434 * - Columns that are part of primary keys must be defined as being NOT NULL
3435 * when they are created. Some code is added in ::CreateIndex to try to adjust the
3436 * column definition if it is not defined correctly, but it is experimental
