Answer 1

In your case, the MERGE statement would look like this:

$DB->query("MERGE INTO periodetojour dst 
            USING ( 
              SELECT '".addslashes($idperiode)."' idperiode, 
                     '2' idjour, 
                     '".addslashes($mardi)."' heure 
            ) src  
            ON src.idperiode = dst.idperiode  
            WHEN MATCHED THEN UPDATE SET  
              dst.idjour = src.idjour, 
              dst.heure = src.heure  
            WHEN NOT MATCHED THEN INSERT (idperiode, idjour, heure)  
              VALUES(src.idperiode, src.idjour, src.heure)");

This is assuming that idperiode is your primary key. If the primary key is composed of (idperiode, idjour) you'll have to adapt the ON clause as well as the WHEN MATCHED THEN UPDATE SET clause accordingly:

            -- [...]
            ON src.idperiode = dst.idperiode  
            AND src.idjour = dst.idjour
            WHEN MATCHED THEN UPDATE SET  
              dst.heure = src.heure
            -- [...]
