Re: Update timestamp automatically when row changes

I found an April 1, 2009 article by Michael Sansoterra that
tells how to do it using new 6.1 features. Unfortunately we are
at 5.4. Is there a way at 5.4 to have the database automatically
update the audit fields when a row changes?


Why not just use SQL CURRENT TIMESTAMP in the SQL DML. Not using SQL DML for the DDL objects, or just prefer to avoid the CURRENT TIMESTAMP? Update & Insert via a VIEW which excludes the TIMESTAMP column; define the TIMESTAMP column with DEFAULT CURRENT TIMESTAMP. If non-SQL RPG, presumably perform according to what is described in the very recent thread on RPG400-L subject: PF Default values
