问题描述
我有这两张桌子.连接密钥"是两个表中都包含的 conID.所以现在我想写一个 select 语句，它会给我这样的东西:
I have these two tables. The connecting "key" is conID which is included in both tables. So now i would like to write select statement which would give me something like this:
John Smith 乳品 22 Texas 4000 smth4
John Smith dairy22 Texas 4000 smth4
Mike Situation glenn32 Jersey 1000 smth1...
Mike Situation glenn32 Jersey 1000 smth1 ...
>表人":
NUM Name lastName address conID ----------------------------------------- 1 John Smith dairy22 Texas 2 Mike Situation glenn32 Jersey 3 Duke Nukem haris48 NYork 4 Queen Lisa court84 London
>表国家"
conID postNum region ------------------------- Jersey 1000 smth1 NYork 2000 smth2 London 3000 smth3 Texas 4000 smth4
<强>！-> NUM 是 AUTO INCREMENT 主键，如果可能的话，我不希望它是输出.
提前感谢您的帮助:))
Thanks for help in advance :))
推荐答案
这应该返回您想要的行，基于 num 列:
This should return the rows you want, based on the num column:
SELECT Name, lastName, address, people.conID, postNum, region FROM people JOIN countries ON people.conID = countries.conID WHERE num=1
