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 | |

3387 | * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE | |
3388 | * --------------------------------------------------- | |
3389 | * | |
3390 | * ORACLE | |
3391 | * - Currently the only database supported by the class to support VIEWS | |
3392 | * | |
3393 | * DBASE | |
3394 | * - Does not support the SQL_TIMESTAMP structure | |
3395 | * - Supports only one cursor and one connect (apparently? with Microsoft driver only?) | |
3396 | * - Does not automatically create the primary index if the 'keyField' param of SetColDef | |
3397 | * is TRUE. The user must create ALL indexes from their program. | |
3398 | * - Table names can only be 8 characters long | |
3399 | * - Column names can only be 10 characters long | |
3400 | * | |
3401 | * SYBASE (all) | |
3402 | * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added | |
3403 | * after every table name involved in the query/join if that tables matching record(s) | |
3404 | * are to be locked | |
3405 | * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above | |
3406 | * | |
3407 | * SYBASE (Enterprise) | |
3408 | * - If a column is part of the Primary Key, the column cannot be NULL | |
3409 | * - Maximum row size is somewhere in the neighborhood of 1920 bytes | |
3410 | * | |
3411 | * MY_SQL | |
3412 | * - If a column is part of the Primary Key, the column cannot be NULL | |
3413 | * - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE | |
3414 | * - Columns that are part of primary or secondary keys must be defined as being NOT NULL | |
3415 | * when they are created. Some code is added in ::CreateIndex to try to adjust the | |
3416 | * column definition if it is not defined correctly, but it is experimental | |
3417 | * - Does not support sub-queries in SQL statements | |
3418 | * | |
3419 | * POSTGRES | |
3420 | * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0 | |
3421 | * - Does not support sub-queries in SQL statements | |
3422 | * | |
3423 | * DB2 | |
3424 | * - Primary keys must be declared as NOT NULL | |
3425 | * - Table and index names must not be longer than 13 characters in length (technically | |
3426 | * table names can be up to 18 characters, but the primary index is created using the | |
3427 | * base table name plus "_PIDX", so the limit if the table has a primary index is 13. | |
3428 | * | |
3429 | * PERVASIVE SQL | |
3430 | * | |
3431 | * INTERBASE | |
3432 | * - Columns that are part of primary keys must be defined as being NOT NULL | |
3433 | * when they are created. Some code is added in ::CreateIndex to try to adjust the | |
3434 | * column definition if it is not defined correctly, but it is experimental | |
