Обсуждение: [jason@netspade.com: DatabaseMetaData.java.diff]
Sorry, I forgot to attach the file. How embarrassing :) -- Jason Davies jason@netspade.com Hi Dave, Here is a diff against current sources of DatabaseMetaData (jdbc2) for fixing getExportedKeys(). Out of interest, why doesn'tit compile under Java 1.1?

Jason, The current sources should be patched as per your patch. I also fixed jdbc1 so it would compile Dave -----Original Message----- From: pgsql-jdbc-owner@postgresql.org [mailto:pgsql-jdbc-owner@postgresql.org] On Behalf Of Jason Davies Sent: November 2, 2001 5:16 PM To: Dave Cramer Cc: PostgreSQL JDBC Subject: [JDBC] [jason@netspade.com: DatabaseMetaData.java.diff] Sorry, I forgot to attach the file. How embarrassing :) -- Jason Davies jason@netspade.com
Dave, Here is yet another patch for DatabaseMetaData which does several things: a) Currently an extra key is returned in both getExportedKeys() and getImportedKeys(). So a foreign key relationship, duplicatekeys are returned. This has been fixed. b) PK_NAME is now returned. c) The whole SQL query has been optimized (no more ugly inner selects). d) The getExportedKeys() and getImportedKeys() implementation has been put into a single getImportedExportedKeys() to saveduplcating the code. e) KEY_SEQ is now also returned. There is however one problem to do with multiple foreign key columns. Should they be returned as a single row, separatedby commas? Or returned in separate rows? By multiple foreign key columns I mean, "alter table ptable add constraintptable_fkey foreign key (pcol1, pcol2) references ftable (fcol1, fcol2)". I think returning separate rows is the most correct way to do it, assuming the SQL statement above is equivalent to 2 separatefkeys.

Your patch has been added to the PostgreSQL unapplied patches list at:
http://candle.pha.pa.us/cgi-bin/pgpatches
I will try to apply it within the next 48 hours. JDBC maintainers will
review.
