// Author: Doug Card
-// Modified by:
-// Mods: Dec, 1998: Added support for SQL statement logging and database
-// cataloging
+// Modified by: George Tasker
+// Bart Jourquin
+// Mark Johnson, wxWindows@mj10777.de
+// Mods: Dec, 1998:
+// -Added support for SQL statement logging and database cataloging
+// Mods: April, 1999
+// -Added QUERY_ONLY mode support to reduce default number of cursors
+// -Added additional SQL logging code
+// -Added DEBUG-ONLY tracking of wxTable objects to detect orphaned DB connections
+// -Set ODBC option to only read committed writes to the DB so all
+// databases operate the same in that respect

+ *
+ * NOTES ABOUT ISSUES SPECIFIC TO EACH DATABASE ENGINE
+ * ---------------------------------------------------
+ *
+ * ORACLE
+ * - Currently the only database supported by the class to support VIEWS
+ *
+ * DBASE
+ * - Does not support the SQL_TIMESTAMP structure
+ * - Supports only one cursor and one connect (apparently? with Microsoft driver only?)
+ * - Does not automatically create the primary index if the 'keyField' param of SetColDef
+ * is TRUE. The user must create ALL indexes from their program.
+ * - Table names can only be 8 characters long
+ * - Column names can only be 10 characters long
*
- * CcolInf *colInf = pDb->GetColumns(tableList);
- * if (colInf)
- * {
- * // Use the column inf
- * .......
- * // Destroy the memory
- * delete [] colInf;
- * }
+ * SYBASE (all)
+ * - To lock a record during QUERY functions, the reserved word 'HOLDLOCK' must be added
+ * after every table name involved in the query/join if that tables matching record(s)
+ * are to be locked
+ * - Ignores the keywords 'FOR UPDATE'. Use the HOLDLOCK functionality described above
+ *
+ * SYBASE (Enterprise)
+ * - If a column is part of the Primary Key, the column cannot be NULL
+ * - Maximum row size is somewhere in the neighborhood of 1920 bytes
+ *
+ * MY_SQL
+ * - If a column is part of the Primary Key, the column cannot be NULL
+ * - Cannot support selecting for update [::CanSelectForUpdate()]. Always returns FALSE
+ * - Columns that are part of primary or secondary keys must be defined as being NOT NULL
+ * when they are created. Some code is added in ::CreateIndex to try to adjust the
+ * column definition if it is not defined correctly, but it is experimental
+ * - Does not support sub-queries in SQL statements
+ *
+ * POSTGRES
+ * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0
+ * - Does not support sub-queries in SQL statements
+ *
+ * DB2
+ * - Primary keys must be declared as NOT NULL
+ * - Table and index names must not be longer than 13 characters in length (technically
+ * table names can be up to 18 characters, but the primary index is created using the
+ * base table name plus "_PIDX", so the limit if the table has a primary index is 13.
+ *
+ * PERVASIVE SQL
+ *
+ * INTERBASE
+ * - Columns that are part of primary keys must be defined as being NOT NULL
+ * when they are created. Some code is added in ::CreateIndex to try to adjust the
+ * column definition if it is not defined correctly, but it is experimental
