   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

   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

2861     created.
2862
2863     - The first one (wxDbColInf *wxDb::GetColumns(wxChar *tableName[], const
2864       wxChar* userID)) calls the second implementation for each separate table
2865       before merging the results. This makes the code easier to maintain as
2866       only one member (the second) makes the real work
2867     - wxDbColInf *wxDb::GetColumns(const wxString &tableName, int *numCols, const
2868       wxChar *userID) is a little bit improved
2869     - It doesn't anymore rely on the type-name to find out which database-type
2870       each column has
2871     - It ends by sorting the columns, so that they are returned in the same
2872       order they were created

3822  *
3823  * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE
3824  * ---------------------------------------------------
3825  *
3826  * ORACLE
3827  *        - Currently the only database supported by the class to support VIEWS
3828  *
3829  * DBASE
3830  *        - Does not support the SQL_TIMESTAMP structure
3831  *        - Supports only one cursor and one connect (apparently? with Microsoft driver only?)
3832  *        - Does not automatically create the primary index if the 'keyField' param of SetColDef
3833  *            is true.  The user must create ALL indexes from their program.
3834  *        - Table names can only be 8 characters long
3835  *        - Column names can only be 10 characters long
3836  *
3837  * SYBASE (all)
3838  *        - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added
3839  *            after every table name involved in the query/join if that tables matching record(s)
3840  *            are to be locked
3841  *        - Ignores the keywords 'FOR UPDATE'.  Use the HOLDLOCK functionality described above
3842  *
3843  * SYBASE (Enterprise)
3844  *        - If a column is part of the Primary Key, the column cannot be NULL
3845  *        - Maximum row size is somewhere in the neighborhood of 1920 bytes
3846  *
3847  * MY_SQL
3848  *        - If a column is part of the Primary Key, the column cannot be NULL
3849  *        - Cannot support selecting for update [::CanSelectForUpdate()].  Always returns FALSE
3850  *        - Columns that are part of primary or secondary keys must be defined as being NOT NULL
3851  *            when they are created.  Some code is added in ::CreateIndex to try to adjust the
3852  *            column definition if it is not defined correctly, but it is experimental
3853  *        - Does not support sub-queries in SQL statements
3854  *
3855  * POSTGRES
3856  *        - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0
3857  *        - Does not support sub-queries in SQL statements
3858  *
3859  * DB2
3860  *        - Primary keys must be declared as NOT NULL
3861  *        - Table and index names must not be longer than 13 characters in length (technically
3862  *          table names can be up to 18 characters, but the primary index is created using the
3863  *          base table name plus "_PIDX", so the limit if the table has a primary index is 13.
