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 |

3337 | * | |
3338 | * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE | |
3339 | * --------------------------------------------------- | |
3340 | * | |
3341 | * ORACLE | |
1e92909e | 3342 | * - Currently the only database supported by the class to support VIEWS |
a2115c88 GT |
3343 | * |
3344 | * DBASE | |
1e92909e GT |
3345 | * - Does not support the SQL_TIMESTAMP structure |
3346 | * - Supports only one cursor and one connect (apparently? with Microsoft driver only?) | |
fdc03678 GT |
3347 | * - Does not automatically create the primary index if the 'keyField' param of SetColDef |
3348 | * is TRUE. The user must create ALL indexes from their program. | |
1e92909e GT |
3349 | * - Table names can only be 8 characters long |
3350 | * - Column names can only be 10 characters long | |
a2115c88 GT |
3351 | * |
3352 | * SYBASE (all) | |
1e92909e GT |
3353 | * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added |
3354 | * after every table name involved in the query/join if that tables matching record(s) | |
3355 | * are to be locked | |
3356 | * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above | |
a2115c88 GT |
3357 | * |
3358 | * SYBASE (Enterprise) | |
1e92909e | 3359 | * - If a column is part of the Primary Key, the column cannot be NULL |
3ca6a5f0 | 3360 | * - Maximum row size is somewhere in the neighborhood of 1920 bytes |
a2115c88 GT |
3361 | * |
3362 | * MY_SQL | |
1e92909e GT |
3363 | * - If a column is part of the Primary Key, the column cannot be NULL |
3364 | * - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE | |
3ca6a5f0 BP |
3365 | * - Columns that are part of primary or secondary keys must be defined as being NOT NULL |
3366 | * when they are created. Some code is added in ::CreateIndex to try to adjust the | |
3367 | * column definition if it is not defined correctly, but it is experimental | |
3368 | * - Does not support sub-queries in SQL statements | |
a2115c88 GT |
3369 | * |
3370 | * POSTGRES | |
23f681ec | 3371 | * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0 |
3ca6a5f0 | 3372 | * - Does not support sub-queries in SQL statements |
a2115c88 | 3373 | * |
a8aa2258 GT |
3374 | * DB2 |
3375 | * - Primary keys must be declared as NOT NULL | |
