ROWIDs on fragmented tables and ESQL/C Updates

We have a table that is distributed across two dbspaces. By default Informix does not assign rowids to fragmented tables. This was causing us a problem with isql forms because they apparantly explicitly select rowids. I didn't understand why an Informix front-end tool wouldn't work with the new Informix engine, but figured I would just add rowids to the table. Then we had a problem with some of our ESQL/C calls. We were doing updates like this: $ update orders set * = ($ORRec) where or_order_num = $ORRec.or_order_num; Well, apparently "*" now includes rowid on fragmented tables that have had rowid added (although it doesn't show up when you look at column names). We started getting errors that the number of columns being updated didn't match the number of values. We have worked around this for the time being by individually specifying each column name rather than "*". Has anyone else experienced this? Do you have a better solution? Thanks.
