Karen,Search RBase Help for SYS_OLD used in the command element WHERE CURRENT
OF SYS_OLD in the BEFORE DELETE trigger.Be aware that access to SYS_OLD record
is only available in the BEFORE DELETE trigger not in an AFTER DELETE trigger
where according to SQL syntax where the update of the archive table should be
updated.

Why I needed the before-delete trigger: no one should ever be deleting data
from this table. And althonugh 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?
