[英]In which table will be foreign key if the relation in two tables is many to one i.e. from 1st table (many ) to second table(one)
如果兩個表中的關系是多對一的，即從第一個表（許多）到第二個表（一個），則在哪個表中將是外鍵。
第一張桌子。 我贏什么？？！
外鍵將在第一個表中，即您的多表中。
外鍵在引用其他表的表中，因此在您的情況下，它將在“許多”表中。 不要被基數所欺騙-可以以1：1關系定義外鍵。
從同一個表中加入具有相同外鍵的 2 個表，但一個表是一對多的
[英]Joining 2 tables which have the same foreign key from same table but one is a one to many
如何從以一對多和多對多關系划分的兩個表中獲取列？
[英]How to get columns from a two table which are divided with one to many and many to many relation?
最好使用兩個多對多表或一個帶有三個外鍵引用的表
[英]Better to use two many to many tables or one table with three Foreign Key References
與EF6中現有表的一對多關系：ALTER TABLE語句與FOREIGN KEY約束沖突
[英]One-to-Many relation to existed table in EF6: The ALTER TABLE statement conflicted with the FOREIGN KEY constraint
將兩個表一對多連接起來，然后將第二個表連接成一個表
[英]Joining two table one to many relationship and then concatenate the second table into one
如何外連接兩個表（主表和多對一子表）以僅從第二個表中獲取一項？
[英]How to outer-join two tables (main and many-to-one sub-table) to get only ONE item from second table?
