DatabaseMetaData.getColumn(). I proposed a patch that would change the number of queries to find out all columns in a table from 2 * N + 1 to 1 (N being the number of columns reported) by using some outer joins. I also fixed the fact that getColumns() only returned columns that had a default defined. OTOH, I did not use to change the code required for obtaining a column's remarks (by using col_description() for 7.2 and requested by Tom Lane). Finally, I have found a way to get all the column details in a single query *and* use col_description() for 7.2 servers. A patch is attached. It overrules Ren? Pijlman's fix for this that was committed just today, but still used N + 1 queries (sorry Ren? ;-) ) I also fixed the return values for TABLE_CAT and TABLE_SCHEM from "" to null, to be more standard compliant (and requested in Ren?'s mail found at http://fts.postgresql.org/db/mw/msg.html?mid=1034253). As always, the JDBC1 version has not been tested as I have no JDK 1.1 Jeroen van Vianen |
