Question

我有一张这样的桌子：

Name          Address                             Matches
Tim Jones     1 London Road, London, W10EU        Peter Jones
Tim Jones     1 London Road, London, W10EU        Smith Jones
Tim Jones     1 London Road, London, W10EU        Tim Jones
Tim Jones     1 London Road, London, W10EU        S Singh
Jack Sons     10 West Street, London, W900U       John Graham
Jack Sons     10 West Street, London, W900U       Jack Sons

我想要这样的结果：

Name          Address                          Matches
Tim Jones     1 London Road, London, W10EU     Peter Jones,Smith johns,Tim Johns, S Singh
Jack Sons     10 West Street, London, W900U    John Graham, Jack Sons
