Sequelize OR 条件对象 [英] Sequelize OR condition object

问题描述

通过创建这样的对象

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

并传入

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

})

它可以像这样漂亮地生成 SQL

It could beautifully generate SQL like this

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

但是，这都是'AND'条件，我如何通过创建条件对象来生成'OR'条件?

However, It is all 'AND' condition, how could I generate 'OR' condition by creating a condition object?

推荐答案

现在好像有别的格式了

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

会生成

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