  • Purpose: timestamps on tables so we know when update queries need to be run
  • Status: probably superceded by data flow tables and procs


<mysql> CREATE TABLE `updates` (

   `Name` varchar(32) NOT NULL COMMENT 'name of thing which gets updated',
   `Updated` datetime COMMENT 'when last updated',
) ENGINE = MYISAM;</mysql>

Function to record an update (not tested): <mysql> CREATE PROCEDURE SetUpdate(IN iName varchar(32))

  REPLACE INTO updates(Name,Updated) values(iName, NOW());

MS Access version

These are notes on table design for vbz's order management system as implemented in Microsoft Access 97.
