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

3350 *
3351 *
3352 * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE
3353 * ---------------------------------------------------
3354 *
3355 * ORACLE
1e92909e 3356 * - Currently the only database supported by the class to support VIEWS
a2115c88
GT		 3357 *
3358 * DBASE
1e92909e
GT		 3359 * - Does not support the SQL_TIMESTAMP structure
3360 * - Supports only one cursor and one connect (apparently? with Microsoft driver only?)
fdc03678
GT		 3361 * - Does not automatically create the primary index if the 'keyField' param of SetColDef
3362 * is TRUE. The user must create ALL indexes from their program.
1e92909e
GT		 3363 * - Table names can only be 8 characters long
3364 * - Column names can only be 10 characters long
a2115c88
GT		 3365 *
3366 * SYBASE (all)
1e92909e
GT		 3367 * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added
3368 * after every table name involved in the query/join if that tables matching record(s)
3369 * are to be locked
3370 * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above
a2115c88
GT		 3371 *
3372 * SYBASE (Enterprise)
1e92909e 3373 * - If a column is part of the Primary Key, the column cannot be NULL
3ca6a5f0 3374 * - Maximum row size is somewhere in the neighborhood of 1920 bytes
a2115c88
GT		 3375 *
3376 * MY_SQL
1e92909e
GT		 3377 * - If a column is part of the Primary Key, the column cannot be NULL
3378 * - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE
3ca6a5f0
BP		 3379 * - Columns that are part of primary or secondary keys must be defined as being NOT NULL
3380 * when they are created. Some code is added in ::CreateIndex to try to adjust the
3381 * column definition if it is not defined correctly, but it is experimental
3382 * - Does not support sub-queries in SQL statements
a2115c88
GT		 3383 *
3384 * POSTGRES
23f681ec 3385 * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0

a2115c88 3387 *
a8aa2258
GT		 3388 * DB2
3389 * - Primary keys must be declared as NOT NULL
2beca662
GT		 3390 * - Table and index names must not be longer than 13 characters in length (technically
3391 * table names can be up to 18 characters, but the primary index is created using the
3392 * base table name plus "_PIDX", so the limit if the table has a primary index is 13.
