我想在列members中的表Person Name中进行搜索，但我希望它返回表中具有相同Family ID的所有成员，并且还要返回表Family表格{{1}}相同ID的家庭数据，尽管搜索将按人名

有任何线索吗？

Answer 1

因为只有一个家庭和许多成员，所以最好做两个查询而不是一个（一个查询，每个成员都有自己的家庭信息副本）。

SELECT Family.* from Family INNER JOIN Members ON Members.FamilyID = Family.Family
WHERE Member.PersonName = "Joe"

SELECT B.* from Members A INNER JOIN Members B ON A.FamilyID = B.FamilyID
WHERE A.PersonName = "Joe"

如果你真的想要一个查询：

SELECT B.*, Family.* FROM Members A INNER JOIN Members B ON A.FamilyID = B.FamilyID, Family
WHERE A.PersonName = "Joe"
AND Family.FamilyID = B.FamilyID

Answer 2

诀窍是加入成员表一次，按名称过滤一个porson，一次显示所有家庭成员尝试一下这方面的事情：

    SELECT members.*, family.adress
    FROM members AS members_1 INNER JOIN (members INNER JOIN family ON     members.familyId=family.FamilyId) ON members_1.familyId = members.familyId
    WHERE (((members_1.name)="john"));

从两个表语句中选择
