1 ///////////////////////////////////////////////////////////////////////////////
2 // Name: src/common/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

2905 before merging the results. This makes the code easier to maintain as
2906 only one member (the second) makes the real work
2907 - wxDbColInf *wxDb::GetColumns(const wxString &tableName, int *numCols, const

2909 - It doesn't anymore rely on the type-name to find out which database-type
2910 each column has

3864 *
3865 *
3866 * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE
3867 * ---------------------------------------------------
3868 *
3869 * ORACLE
3870 * - Currently the only database supported by the class to support VIEWS
3871 *
3872 * DBASE
3873 * - Does not support the SQL_TIMESTAMP structure
3874 * - Supports only one cursor and one connect (apparently? with Microsoft driver only?)
3875 * - Does not automatically create the primary index if the 'keyField' param of SetColDef
3876 * is true. The user must create ALL indexes from their program.
3877 * - Table names can only be 8 characters long
3878 * - Column names can only be 10 characters long
3879 *
3880 * SYBASE (all)
3881 * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added
3882 * after every table name involved in the query/join if that tables matching record(s)
3883 * are to be locked
3884 * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above
3885 *
3886 * SYBASE (Enterprise)
3887 * - If a column is part of the Primary Key, the column cannot be NULL
3888 * - Maximum row size is somewhere in the neighborhood of 1920 bytes
3889 *
3890 * MY_SQL
3891 * - If a column is part of the Primary Key, the column cannot be NULL
3892 * - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE
3893 * - Columns that are part of primary or secondary keys must be defined as being NOT NULL
3894 * when they are created. Some code is added in ::CreateIndex to try to adjust the
3895 * column definition if it is not defined correctly, but it is experimental
3896 * - Does not support sub-queries in SQL statements
3897 *
3898 * POSTGRES
3899 * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0
3900 * - Does not support sub-queries in SQL statements
3901 *
3902 * DB2
3903 * - Primary keys must be declared as NOT NULL
3904 * - Table and index names must not be longer than 13 characters in length (technically
3905 * table names can be up to 18 characters, but the primary index is created using the
3906 * base table name plus "_PIDX", so the limit if the table has a primary index is 13.
3907 *
3908 * PERVASIVE SQL
3909 *
3910 * INTERBASE
3911 * - Columns that are part of primary keys must be defined as being NOT NULL
3912 * when they are created. Some code is added in ::CreateIndex to try to adjust the
3913 * column definition if it is not defined correctly, but it is experimental
