SQL UPDATE statements (confused again)

[K]

What I found was that revdb_execute returns the number of rows or the error.  The error is not only "revdberr,description" but also "ERROR: description".  I create a function to test for the cases and return true or false.

if queryFailed( tRows ) then 
  return "Error process query [" & getLastError() & "]"
end if 

NOTE queryFailed(); querySucceded() ; failed() and succeded() all setLastError() prior to making any judgements.
