Question

If one has three fields in a db that they are querying an object by.... One of these fields must always be an associations id. Concerning the other two fields "only one needs to be true"

What interpretation do you take or make of "only one needs to be true"?

Answer 1

I'd read that as OR , only one needs to be true, but I won't object if the other is too.

If I meant EXCLUSIVE OR I would say "exactly one must be true".

However, the only way to be sure what was intended is to ask the author, who may well surprise you by telling you about yet a further condition ;-(

Answer 2

我将其理解为意思是，原始搜索指定了一个字段必须为assoc的条件，再加上其余两个字段的2个条件，但是如果这两个字段之一（加上assoc字段）为真，则可以进行选择。

Answer 3

Well, I would read it as "one of the other two fields must match the search criterion". Beyond that, I would need more information.
