Sql server 在sql中重新排列逗号分隔的值

嗨，我有两张桌子一张桌子有县信息 另一个有行数据

乡村餐桌看起来像

Country_ID  Region_ID   Country_Name              Abbreviation Priority
----------- ----------- ------------------------- ------------ -----------
1           1           United States             USA          1
2           1           US                        USA          1
3           1           Canada                    CA           2
4           2           United Kingdom            UK           1
5           2           Germany                   DE           1
6           2           France                    FR           1
7           2           Italy                     IT           1
8           2           Spain                     ES           1
9           2           The Netherlands           NL           1
10          2           Poland                    PL           2
11          2           Russia                    RU           2

而RowData就像

Tr_ID       Countrys
----------- --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
729541      Germany,United Kingdom
729553      Italy,Poland,Russia,Spain
729580      Austria,Finland,France,Germany,Ireland,Italy,Poland,Portugal,Romania,Russia,Slovakia,Spain,Sweden,Switzerland,The Netherlands,United Kingdom
729726      Italy,Spain,United Kingdom
729737      Austria,United Kingdom

我想根据county表中给出的优先级重新排列county的in

优先1县应首先发生扩孔，然后用逗号重复 请帮我做这个

谢谢

您正在使用哪个数据库？您是否需要所有优先级为1的国家/地区按字母顺序排列？我使用的是sql server 2008。需要所有优先级为1的国家/地区，但不按字母顺序。注意：

RowData

中缺少的国家/地区将被删除。
