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 | |

3861 | * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE | |
3862 | * --------------------------------------------------- | |
3863 | * | |
3864 | * ORACLE | |
3865 | * - Currently the only database supported by the class to support VIEWS | |
3866 | * | |
3867 | * DBASE | |
3868 | * - Does not support the SQL_TIMESTAMP structure | |
3869 | * - Supports only one cursor and one connect (apparently? with Microsoft driver only?) | |
3870 | * - Does not automatically create the primary index if the 'keyField' param of SetColDef | |
3871 | * is true. The user must create ALL indexes from their program. | |
3872 | * - Table names can only be 8 characters long | |
3873 | * - Column names can only be 10 characters long | |
3874 | * | |
3875 | * SYBASE (all) | |
3876 | * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added | |
3877 | * after every table name involved in the query/join if that tables matching record(s) | |
3878 | * are to be locked | |
3879 | * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above | |
3880 | * | |
3881 | * SYBASE (Enterprise) | |
3882 | * - If a column is part of the Primary Key, the column cannot be NULL | |
3883 | * - Maximum row size is somewhere in the neighborhood of 1920 bytes | |
3884 | * | |
3885 | * MY_SQL | |
3886 | * - If a column is part of the Primary Key, the column cannot be NULL | |
3887 | * - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE | |
3888 | * - Columns that are part of primary or secondary keys must be defined as being NOT NULL | |
3889 | * when they are created. Some code is added in ::CreateIndex to try to adjust the | |
3890 | * column definition if it is not defined correctly, but it is experimental | |
3891 | * - Does not support sub-queries in SQL statements | |
3892 | * | |
3893 | * POSTGRES | |
3894 | * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0 | |
3895 | * - Does not support sub-queries in SQL statements | |
3896 | * | |
3897 | * DB2 | |
3898 | * - Primary keys must be declared as NOT NULL | |
3899 | * - Table and index names must not be longer than 13 characters in length (technically | |
3900 | * table names can be up to 18 characters, but the primary index is created using the | |
3901 | * base table name plus "_PIDX", so the limit if the table has a primary index is 13. | |
3902 | * | |
3903 | * PERVASIVE SQL | |
3904 | * | |
3905 | * INTERBASE | |
3906 | * - Columns that are part of primary keys must be defined as being NOT NULL | |
3907 | * when they are created. Some code is added in ::CreateIndex to try to adjust the | |
3908 | * column definition if it is not defined correctly, but it is experimental | |
