Обсуждение: getMetaData().getTables() behaviour with JDBC3 8.3 & 8.4 drivers on windows

The PostgreSQL driver appears to be causing some unexpected behaviour for the OpenNMS installer on Windows.

In the following code snippet, the table row set returned includes TABLEs, SEQUENCEs, and INDEXes. Shouldn't getTables
befiltering out and returning only tables and views?
 

    public void databaseSetUser() throws SQLException {
        Connection adminConn = getAdminConnection();
        ResultSet rs = adminConn.getMetaData().getTables(null, "public", "%", null);
        HashSet<String> objects = new HashSet<String>();
        while (rs.next()) {
            m_out.println(rs.getString("TABLE_NAME")+" "+ rs.getString("TABLE_TYPE") +" "+ rs.getString("REMARKS"));
            objects.add(rs.getString("TABLE_NAME"));
        }
        PreparedStatement st = getAdminConnection().prepareStatement("ALTER TABLE ? OWNER TO ?");
        for (String objName : objects) {
            st.setString(1, objName);
            st.setString(2, m_user);
            m_out.println("Would perform ALTER TABLE " + objName + " OWNER TO " + m_user );
            /* st.execute(); */
        }
        st.close();
    }

In your argument for getTables(catalog, schemaPattern, tableNamePattern,
tableTypes) you
have specified a null for the tableTypes. That I believe does not place
any restrictions on
the returned table, so VIEW and other types will be returned.

types - A list of table types, which must be from the list of table
           types returned from getTableTypes(), to include; null returns
            all types.
