Tom,
My version is: 7.2.3-RH
Is this my problem? The example you mention would be great to see if it can be
located. I'm trying to write a function that will return the last record in a
sequence of logs, "last" being defined by an ORDER BY statement containing
time stamp criteria in conjuction with other data. The function would always
be called by trigger code.
Thanks...
