排序或条件对象

Question

通过创建这样的对象

var condition=
{
  where:
  {
     LastName:"Doe"，
     FirstName:["John","Jane"],
     Age:{
       gt:18
     }
  }    
}

并传递给

Student.findAll(condition)
.success(function(students){

})

它可以像这样漂亮地生成SQL

"SELECT * FROM Student WHERE LastName='Doe' AND FirstName in ("John","Jane") AND Age>18"

但是，这都是“ AND”条件，如何通过创建条件对象来生成“ OR”条件？

Answer 1

似乎现在有另一种格式

where: {
    LastName: "Doe",
    $or: [
        {
            FirstName: 
            {
                $eq: "John"
            }
        }, 
        {
            FirstName: 
            {
                $eq: "Jane"
            }
        }, 
        {
            Age: 
            {
                $gt: 18
            }
        }
    ]
}

会产生

WHERE LastName='Doe' AND (FirstName = 'John' OR FirstName = 'Jane' OR Age > 18)
