Ruby ActiveRecord和sql元组支持

Question

ActiveRecord是否支持where子句中的元组,假设底层数据库有效？

结果where子句看起来像:

where (name, address) in (('John', '123 Main St'))

我试过了:

Person.where({[:name, :address] => ['John', '123 Main St']})

它不起作用.

Answer 1

tupleArray = [['John', '123 Main St'],['Jane', '124 Main St']]
Person.where("(name, address) IN (#{(['(?)']*tupleArray.size).join(', ')})", *tupleArray)

Answer 2

Person.where("(name, address) IN ((?))", ['John', '123 Main St'])
