+// Modified by: George Tasker
+// 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

+ * ---------------------------------------------------
+ *
+ * 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
+ *
+ * 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
+ *
+ * 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
+ *
+ * POSTGRES
+ * - Does not support the keywords 'ASC' or 'DESC' as of release v6.5.0
+ *
