, it is considered a one-to-many?如果我有这样的关系:
1 - 0..1
,它被认为是一对多?
the only options that i have in mysql workbench are:我在 mysql 工作台中的唯一选项是:
1:1, 1:n, n:n...
thanks!谢谢!
No, this is a 1:1 (one-to-one) relationship.不,这是 1:1(一对一)的关系。 It's just that there isn't always another one that relates to the first one:)
只是并不总是有另一个与第一个相关:)
