What is the normal way to preform a "insert with replace" on a row in a relational database (specifically postgresql)? I've got a database that (logically) represents a set of items, where each item has a primary key represented by two columns (id and name). If that key isn't in the database, I want to insert the item. If that key is in the database, I want to update the item. I have no need to retain the previous values. The interface is through jdbc. I assume I could try the update first and then, if the update generates an exception, perform an insert, but is there a way to do the same with a single command? (The data is such that the update will fail in the majority of cases.) Thanks! -- Steve Wampler- SOLIS Project, National Solar Observatory [EMAIL PROTECTED]
