1 ///////////////////////////////////////////////////////////////////////////////
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
18 // Created: 9.96

3853 * Some manufacturers support the minimum Level 1 compliancy, and others up

3859 *
3860 *
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
