  9. web site – startpage

  10. PDA view – startpage

  11. <?xml version="1.0" encoding="utf-8"?> <xsp:page xmlns:xsp="http://apache.org/xsp" xmlns:esql="http://apache.org/cocoon/SQL/v2" xmlns:xsp-request="http://apache.org/xsp/request/2.0" language="java"> ... <content> <esql:execute-query> <esql:query> select id, spieler, tore, spiele, gelb, 2min, rot from mis_torschuetzen </esql:query> <esql:results> <rowset> <!-- für jede einzelene Ergebniszeile --> <esql:row-results> <row> <!-- damit holt man einen bestimmten Datensatz aus der Zeile der Tabelle --> <id><esql:get-int column="id"/></id> <spieler><esql:get-string column="spieler"/></spieler> <tore><esql:get-string column="tore"/></tore> <spiele><esql:get-string column="spiele"/></spiele> <gelb><esql:get-int column="gelb"/></gelb> <min2><esql:get-int column="2min"/></min2> <rot><esql:get-int column="rot"/></rot> </row> </esql:row-results> </rowset> </esql:results> </esql:execute-query> </content> ... </xsp:page>
