Bob: Here's my answers to your thoughtful questions:
Was the Deletedby value actually null or a blank? If it was blank, then the
computer name would not be captured with the "is null" parameter. Good
question. I did a "sel count(*) from tmpclaimsdeleted where deletedby is null"
and all records come up. So it is a Null
Just in case there is some odd condition with nulls, you could set the var
vtext = ( (CVAL('NetUser')) & (Cval('Computer')) ) and capture both all the
time, thus avoiding the IF nulls. I could try that, thanks for the suggestion
I see that you are using double quotes?
Yes, using double quotes
My help states the cval syntax is 'Computer' instead of 'ComputerName' ?
My test shows that cval "computer" and "computername" return the same result

A couple of thoughts...(some obvious, but it never hurts to ask!)

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?
