| 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 |

| 3385 | * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE |
| 3386 | * --------------------------------------------------- |
| 3387 | * |
| 3388 | * ORACLE |
| 3389 | * - Currently the only database supported by the class to support VIEWS |
| 3390 | * |
| 3391 | * DBASE |
| 3392 | * - Does not support the SQL_TIMESTAMP structure |
| 3393 | * - Supports only one cursor and one connect (apparently? with Microsoft driver only?) |
| 3394 | * - Does not automatically create the primary index if the 'keyField' param of SetColDef |
| 3395 | * is TRUE. The user must create ALL indexes from their program. |
| 3396 | * - Table names can only be 8 characters long |
| 3397 | * - Column names can only be 10 characters long |
| 3398 | * |
| 3399 | * SYBASE (all) |
| 3400 | * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added |
| 3401 | * after every table name involved in the query/join if that tables matching record(s) |
| 3402 | * are to be locked |
| 3403 | * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above |
| 3404 | * |
| 3405 | * SYBASE (Enterprise) |
| 3406 | * - If a column is part of the Primary Key, the column cannot be NULL |
| 3407 | * - Maximum row size is somewhere in the neighborhood of 1920 bytes |
| 3408 | * |
| 3409 | * MY_SQL |
| 3410 | * - If a column is part of the Primary Key, the column cannot be NULL |
| 3411 | * - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE |
| 3412 | * - Columns that are part of primary or secondary keys must be defined as being NOT NULL |
| 3413 | * when they are created. Some code is added in ::CreateIndex to try to adjust the |
| 3414 | * column definition if it is not defined correctly, but it is experimental |
| 3415 | * - Does not support sub-queries in SQL statements |
| 3416 | * |
| 3417 | * POSTGRES |
| 3418 | * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0 |
| 3419 | * - Does not support sub-queries in SQL statements |
| 3420 | * |
| 3421 | * DB2 |
| 3422 | * - Primary keys must be declared as NOT NULL |
| 3423 | * - Table and index names must not be longer than 13 characters in length (technically |
| 3424 | * table names can be up to 18 characters, but the primary index is created using the |
| 3425 | * base table name plus "_PIDX", so the limit if the table has a primary index is 13. |
| 3426 | * |
| 3427 | * PERVASIVE SQL |
| 3428 | * |
| 3429 | * INTERBASE |
| 3430 | * - Columns that are part of primary keys must be defined as being NOT NULL |
| 3431 | * when they are created. Some code is added in ::CreateIndex to try to adjust the |
| 3432 | * column definition if it is not defined correctly, but it is experimental |
