My mongoDB statistical query is not performing as expected even after I aggregate all of the queries into a mongoDB aggregation. The final query result still contains an incorrect value.
[ {"$match": {"agencyId": ObjectId("649aedc8a827e7aed6ea7b79") // Replace with the actual agency ID } }, {"$lookup": {"from": "OperationTransfer", // Name of the transfer collection"localField": "_id", // Field in operations referencing transfer document"foreignField": "operationId", // Field in transfer collection"as": "transfer" } }, {"$unwind": {"path": "$transfer","preserveNullAndEmptyArrays": true // Preserve operations without a transfer reference } }, {"$group": {"_id": "$status","count": { "$sum": 1 },"countWithBabySeats": {"$sum": {"$cond": [{ "$eq": ["$babySeats", true] }, 1, 0] } },"countInTruck": {"$sum": {"$cond": [{ "$eq": ["$inTruck", true] }, 1, 0] } },"countTransferWithNonEmptyOriginDestiny": {"$sum": {"$cond": [ {"$and": [ { "$ne": ["transfer", null] }, { "$ne": ["transfer.origin", ""] }, { "$ne": ["transfer.destiny", ""] } ] }, 1, 0 ] } } } }]countTransferWithNonEmptyOriginDestiny in this stage, i can't check if i have the transfer object and if it contains the appropriate attribute with right values
I used $set to change the satge in order to update the result documents, but the values were still incorrect.
