title: How do I get constraint details from the name in Informix?
body: <p>When programming a large transaction (lots of inserts, deletes, updates) and thereby violating a constraint in Informix (v10, but should apply to other versions too) I get a not very helpful message saying, for example, I violated constraint r190_710. How can I find out which table(s) and key(s) are covered by a certain constraint I know only the name of?</p>
