问题

如何从mod表中选择Id,即使查询中提供的数据顺序与我的SQLite数据库中的顺序不同?

mod表:

Id Secondary1 Secondary2 Secondary3 Secondary4
1 offense tenacity speed defense
2 offense speed protection potency
… … … … …

例如,如果我有次要属性为speed、tenacity、defense和offense的mod,我希望查询的输出是"1"。

我为每个部分的排列组合(speed、tenacity、defense、offense;speed、defense、tenacity、offense;等等)制作了查询,但这不是一个简洁的解决方案,似乎有些过度。

英文:

How to select Id from mod table even if data given in the query is not in the same order as the one in my SQLite database?

mod table:

Id Secondary1 Secondary2 Secondary3 Secondary4
1 offense tenacity speed defense
2 offense speed protection potency
… … … … …

For example if I have the mod with secondaries speed, tenacity, defense and offense I want the query output to be "1".

I made a query for every partial permutation (speed, tenacity, defense, offense; speed, defense, tenacity, offense; etc.) but it isn't a sexy solution and seems overkill.

一个简单的解决方案可以是多次使用 IN

例如:

select * from t
where Secondary1 in ('速度', '坚韧', '防御', '进攻')
  and Secondary2 in ('速度', '坚韧', '防御', '进攻')
  and Secondary3 in ('速度', '坚韧', '防御', '进攻')
  and Secondary4 in ('速度', '坚韧', '防御', '进攻')
英文:

A simple solution could be to just use IN multiple times.

For example:

select * from t
where Secondary1 in ('speed', 'tenacity', 'defense', 'offense')
  and Secondary2 in ('speed', 'tenacity', 'defense', 'offense')
  and Secondary3 in ('speed', 'tenacity', 'defense', 'offense')
  and Secondary4 in ('speed', 'tenacity', 'defense', 'offense')
