Hi there, Here's a mini-problem I'm fiddling with. I have a table with *two* cross-references to the same other table. And I want to make a view (or do a query) which uses them both. My problem is that so far I can get one out but not both; it's got to be some syntax thing I'm messing up. Existing tables: bond ---- id integer primary key res1 references residue res2 references residue (other stuff) residue ------- id integer primary key code char(3) (other stuff) Desired outcome: nice_human_readable_details_about_bond ------------- bond.id, bond.res1's code, bond.res2's code, (other details from bond table) Cath Lawrence, Cath.Lawrence@anu.edu.au Senior Scientific Programmer, Centre for Bioinformation Science, John Curtin School of Medical Research (room 4088) Australian National University, Canberra ACT 0200 ph: (02) 61257959 mobile: 0421-902694 fax: (02) 61252595
