我有一个包含许多类似结构化文档的集合,两个文档看起来像

输入:

{ 
    "_id": ObjectId("525c22348771ebd7b179add8"), 
    "cust_id": "A1234", 
    "score": 500, 
    "status": "A"
    "clear": "No"
}

{ 
    "_id": ObjectId("525c22348771ebd7b179add9"), 
    "cust_id": "A1234", 
    "score": 1600, 
    "status": "B"
    "clear": "No"
}

默认情况下clear,所有文档都是"No",

要求:我必须添加所有文件的分数cust_id,只要它们属于status "A"和status "B".如果score超过2000那么我必须更新所有文档的clear属性"Yes"相同cust_id.

预期产量:

{ 
    "_id": ObjectId("525c22348771ebd7b179add8"), 
    "cust_id": "A1234", 
    "score": 500, 
    "status": "A"
    "clear": "Yes"
}

{
    "_id": ObjectId("525c22348771ebd7b179add9"), 
    "cust_id": "A1234", 
    "score": 1600, 
    "status": "B"
    "clear": "Yes"
}

是的,因为1600 + 500 = 2100,2100> …
