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

2895 - The first one (wxDbColInf *wxDb::GetColumns(wxChar *tableName[], const

2897 before merging the results. This makes the code easier to maintain as
2898 only one member (the second) makes the real work
2899 - wxDbColInf *wxDb::GetColumns(const wxString &tableName, int *numCols, const
2900 wxChar *userID) is a little bit improved
2901 - It doesn't anymore rely on the type-name to find out which database-type
2902 each column has
2903 - It ends by sorting the columns, so that they are returned in the same
2904 order they were created

3848 * Be aware that not all database engines use the exact same syntax, and not

3850 * Some manufacturers support the minimum Level 1 compliancy, and others up
3851 * through Level 3. Others support subsets of features for levels above 1.
3852 *
3853 * If you find an inconsistency between the wxDb class and a specific database

3855 * the area where behavior is non-conforming with the other databases.
3856 *
3857 *
3858 * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE
3859 * ---------------------------------------------------
3860 *
3861 * ORACLE
3862 * - Currently the only database supported by the class to support VIEWS
3863 *
3864 * DBASE
3865 * - Does not support the SQL_TIMESTAMP structure
3866 * - Supports only one cursor and one connect (apparently? with Microsoft driver only?)
3867 * - Does not automatically create the primary index if the 'keyField' param of SetColDef
3868 * is true. The user must create ALL indexes from their program.
3869 * - Table names can only be 8 characters long
3870 * - Column names can only be 10 characters long
3871 *
3872 * SYBASE (all)
3873 * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added
3874 * after every table name involved in the query/join if that tables matching record(s)
3875 * are to be locked
3876 * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above
3877 *
3878 * SYBASE (Enterprise)
3879 * - If a column is part of the Primary Key, the column cannot be NULL
3880 * - Maximum row size is somewhere in the neighborhood of 1920 bytes
3881 *
3882 * MY_SQL
3883 * - If a column is part of the Primary Key, the column cannot be NULL
3884 * - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE
3885 * - Columns that are part of primary or secondary keys must be defined as being NOT NULL
3886 * when they are created. Some code is added in ::CreateIndex to try to adjust the
3887 * column definition if it is not defined correctly, but it is experimental
3888 * - Does not support sub-queries in SQL statements
3889 *
3890 * POSTGRES
3891 * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0
3892 * - Does not support sub-queries in SQL statements
3893 *
3894 * DB2
3895 * - Primary keys must be declared as NOT NULL
3896 * - Table and index names must not be longer than 13 characters in length (technically
3897 * table names can be up to 18 characters, but the primary index is created using the
3898 * base table name plus "_PIDX", so the limit if the table has a primary index is 13.
3899 *
3900 * PERVASIVE SQL
3901 *
3902 * INTERBASE
3903 * - Columns that are part of primary keys must be defined as being NOT NULL
3904 * when they are created. Some code is added in ::CreateIndex to try to adjust the
3905 * column definition if it is not defined correctly, but it is experimental
