Karen,

Quick question: do you feel that records are/were effectively deleted or do you 
have NULL entries even though nothing was deleted?

BR, Adrian

Betreff: [RBASE-L] - Delete Trigger mystery?

 

 

Why I needed the before-delete trigger:  no one should ever be deleting data 
from this table.  And although they have the full version of RBase, no one 
knows how to "get to the R> prompt".  There is a monthend routine that the 
senior user runs that will delete a batch of data, but that's all (we remove 
the trigger before this monthend routine, then put it back on)

 

Yet every now and then we find data mysteriously disappeared.

 

So I created a before-delete trigger.  It takes the record to be deleted and 
appends it to an archive table.  3 columns in the archive table will hold the 
deleted date / time and the user who deleted it.  Works perfectly at my 
development environment and when I test it at the place where the database is 
installed.  Records the date, time and the user.

 

However, twice now we have found records in that archive table that had been 
deleted (hundreds at a time).  The records had the deleted date/time but had NO 
user name.  

 

Here's the code I use in my stored procedure.  The DeletedDate and DeletedTime 
works fine, it gets updated every time.  There is no login to this app, so I 
grab the NetUser (used many times in the application for other things, 
successfully).  The first time that the archive had no user name, I modified 
the stored procedure to grab the ComputerName.  But still, nothing.....

 

 

   SET VAR vText TEXT = NULL
   SET VAR vText = (CVAL("NetUser"))
   IF vText IS NULL THEN
     SET VAR vText = (CVAL("ComputerName"))
   ENDIF

   UPDATE ClaimsDeleted SET DeletedDate = .#DATE, DeletedTime = .#TIME, +
     DeletedBy = .vText WHERE claim = .spClaim

 

 

 

Can anyone think of anything else I can trap that would help me figure out 
how/when the records got deleted?  

 

Or does anyone know how records could get deleted when there actually is no 
NetUser or ComputerName?  

 

 

Karen
