我找到了ConcatRelated()函数[http://allenbrowne.com/func-concat.html],它似乎做了我想要的,但我需要输入两个键而不是一个。< / p>
我的数据如下:
Chain Store Warehouse
Walmart Tucson Phoenix
Walmart Tucson Flagstaff
Walmart Phoenix Phoenix
Bi-Lo Phoenix Phoenix
Bi-Lo Phoenix Flagstaff
我需要根据Chain和Store进行连接:
Chain Store Warehouses
Walmart Tucson Phoenix, Flagstaff
Walmart Phoenix Phoenix
Bi-Lo Phoenix Phoenix, Flagstaff
你能帮我解决一下我需要在括号内使用的论点吗?
答案 0 :(得分:2)
你可以这样写:
SELECT Distinct
tbl.Chain,
tbl.Store,
ConcatRelated("Warehouse","tbl","Chain=""" & [Chain] & """ and Store=""" & [Store] & """") AS Warehouses
FROM tbl;
