Some Unicode compilation fixes. This Unicode stuff in file functions is
[wxWidgets.git] / src / common / db.cpp
1 ///////////////////////////////////////////////////////////////////////////////
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.

3334 *
3335 * ORACLE
3336 * - Currently the only database supported by the class to support VIEWS
3337 *
3338 * DBASE
3339 * - Does not support the SQL_TIMESTAMP structure
3340 * - Supports only one cursor and one connect (apparently? with Microsoft driver only?)
3341 * - Does not automatically create the primary index if the 'keyField' param of SetColDef
3342 * is TRUE. The user must create ALL indexes from their program.
3343 * - Table names can only be 8 characters long
3344 * - Column names can only be 10 characters long
3345 *
3346 * SYBASE (all)
3347 * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added
3348 * after every table name involved in the query/join if that tables matching record(s)
3349 * are to be locked
3350 * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above
3351 *
3352 * SYBASE (Enterprise)
3353 * - If a column is part of the Primary Key, the column cannot be NULL
3354 * - Maximum row size is somewhere in the neighborhood of 1920 bytes
3355 *
3356 * MY_SQL
3357 * - If a column is part of the Primary Key, the column cannot be NULL
3358 * - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE
3359 * - Columns that are part of primary or secondary keys must be defined as being NOT NULL
3360 * when they are created. Some code is added in ::CreateIndex to try to adjust the
3361 * column definition if it is not defined correctly, but it is experimental
3362 * - Does not support sub-queries in SQL statements
3363 *
3364 * POSTGRES
3365 * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0
3366 * - Does not support sub-queries in SQL statements
3367 *
3368 * DB2
3369 * - Primary keys must be declared as NOT NULL
