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 |

2429 | These are tentative new GetColumns members which should be more database | |
eedb1543 | 2430 | independant and which always returns the columns in the order they were |
3ca6a5f0 BP |
2431 | created. |

2433 | - The first one (wxDbColInf *wxDb::GetColumns(wxChar *tableName[], const |
2434 | wxChar* userID)) calls the second implementation for each separate table | |
eedb1543 | 2435 | before merging the results. This makes the code easier to maintain as |
3ca6a5f0 | 2436 | only one member (the second) makes the real work |
4fdae997 GT |
2437 | - wxDbColInf *wxDb::GetColumns(const wxString &tableName, int *numCols, const |
2438 | wxChar *userID) is a little bit improved | |
eedb1543 | 2439 | - It doesn't anymore rely on the type-name to find out which database-type |
3ca6a5f0 | 2440 | each column has |
eedb1543 | 2441 | - It ends by sorting the columns, so that they are returned in the same |
3ca6a5f0 | 2442 | order they were created |

3343 | * | |
3344 | * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE | |
3345 | * --------------------------------------------------- | |
3346 | * | |
3347 | * ORACLE | |
1e92909e | 3348 | * - Currently the only database supported by the class to support VIEWS |
a2115c88 GT |
3349 | * |
3350 | * DBASE | |
1e92909e GT |
3351 | * - Does not support the SQL_TIMESTAMP structure |
3352 | * - Supports only one cursor and one connect (apparently? with Microsoft driver only?) | |
fdc03678 | 3353 | * - Does not automatically create the primary index if the 'keyField' param of SetColDef |
a144affe | 3354 | * is TRUE. The user must create ALL indexes from their program. |
1e92909e GT |
3355 | * - Table names can only be 8 characters long |
3356 | * - Column names can only be 10 characters long | |
a2115c88 GT |
3357 | * |
3358 | * SYBASE (all) | |
1e92909e GT |
3359 | * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added |
3360 | * after every table name involved in the query/join if that tables matching record(s) | |
3361 | * are to be locked | |
3362 | * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above | |
a2115c88 GT |
3363 | * |
3364 | * SYBASE (Enterprise) | |
1e92909e | 3365 | * - If a column is part of the Primary Key, the column cannot be NULL |
3ca6a5f0 | 3366 | * - Maximum row size is somewhere in the neighborhood of 1920 bytes |
a2115c88 GT |
3367 | * |
3368 | * MY_SQL | |
1e92909e | 3369 | * - If a column is part of the Primary Key, the column cannot be NULL |
a144affe | 3370 | * - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE |
3ca6a5f0 BP |
3371 | * - Columns that are part of primary or secondary keys must be defined as being NOT NULL |
3372 | * when they are created. Some code is added in ::CreateIndex to try to adjust the | |
3373 | * column definition if it is not defined correctly, but it is experimental | |
3374 | * - Does not support sub-queries in SQL statements | |
a2115c88 GT |
3375 | * |
3376 | * POSTGRES | |
23f681ec | 3377 | * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0 |
3ca6a5f0 | 3378 | * - Does not support sub-queries in SQL statements |
a2115c88 | 3379 | * |
a8aa2258 GT |
3380 | * DB2 |
3381 | * - Primary keys must be declared as NOT NULL | |
2beca662 GT |
3382 | * - Table and index names must not be longer than 13 characters in length (technically |
3383 | * table names can be up to 18 characters, but the primary index is created using the | |
3384 | * base table name plus "_PIDX", so the limit if the table has a primary index is 13. | |
3385 | * | |
