When an application program accesses the HiRDB system with ODBC, some of the facilities cannot be used.

• Access using the row interface
  Queries with ROW specifications, UPDATE statements, and INSERT statements cannot be executed.
  
• Update and deletion using a cursor
  Update and deletion using CURRENT OF cursor-name cannot be executed. However, if the cursor library facility is used, the cursor library can sometimes execute such operations to change CURRENT OF cursor-name to a WHERE condition.
  
• Portable cursors
  Portable cursors (cursors with the WITH HOLD specification or cursors defined by queries with the UNTIL DISCONNECT specification) cannot be used.
