java - Mongodb java输入两个日期字段之间的日期

Question

我想创建一个查询，例如:

SELECT * FROM MY_TABLE WHERE {MY_DATE_1} BETWEEN {DB_COLUMN_1} AND {DB_COLUMN_2} OR {MY_DATE_2} BETWEEN {DB_COLUMN_1} AND {DB_COLUMN_2})

我知道如何做相反的事情(两个变量之间的字段)，因为 BasicDBObject 将字符串(我猜是字段名称)作为第一个参数而不是日期。谢谢!

我猜你想使用$or像sql一样查询

这里是java的演示

        BasicDBObject query = new BasicDBObject();
        BasicDBObject condition1 = new BasicDBObject("fieldA",new BasicDBObject("$gt","2018-06-02 12:20:00").append("$lt","2019-06-02 12:20:00"));
        BasicDBObject condition2 = new BasicDBObject("fieldB",new BasicDBObject("$gt","2018-06-02 12:20:00").append("$lt","2019-06-02 12:20:00"));

        BasicDBList condList = new BasicDBList();
        condList.add(condition1);
        condList.add(condition2);
        query.put("$or" ,condList);

        collection.find(query);

$gt 表示大于，$lt 表示小于。
