how can i write this sql in monogb query
select distinct(Users.id)
,userName,gender
,displayPic
,dob
,aboutUser
,jobTitle
,company
,school
,dontShowAge
,makeDistanceInvisible
, isUserVerified
, (DATE_FORMAT(NOW(), '%Y') - DATE_FORMAT(dob, '%Y')) as age
, ( 6371 * acos ( cos ( radians(?) ) * cos( radians( locLattitude ) ) * cos( radians( locLongitude ) - radians(?) ) + sin ( radians(?) ) * sin( radians( locLattitude ) ) ) ) as distance,religion.religion_name
FROM Users
INNER JOIN religion
ON(Users.religion = religion.id)
WHERE Users.displayPic <> 'NULL'
AND gender = ?
AND showMeTinder = '1'
AND Users.id <> ?
AND ( (
select count(pairID)
from Swipe
where senderID = ?
AND receiverID = Users.id) = 0
AND ( ( select count(pairID) from Swipe where receiverID = ?
AND senderID = Users.id
AND NOT (swipeType = 'like' OR 'superlike') ) = 0 ) )
LIMIT 10
Here is the MongoDB code I wrote
let aggregate = [
{ $match: { userID: { $ne: data.userID }, userName: { $ne: "" }, userName: { $ne: undefined } } },
{ $sort: { _id: -1 } },
{
$project: {
_id: 0, userID: 1, pairid : {
$cond: { if: { $gte: ["$userID", data.userID] }, then: { $concat: [ data.userID, "$userID" ] }, else: { $concat: [ "$userID", data.userID, ] } }
}
}
},
{
$lookup:
{
from: swipeCollection,
localField: 'pairid',
foreignField: "pairID",
as: "data"
}
},
{ $unwind: "$data" },
{
$project: {
_id: 0, userID : 1, "data.swipeType": 1,
}
},
{ $limit: 3 },
]
the issue here is that it return swipe data
what am trying to solve is get data from user collection then check it in swipe collections then return the combination of both user and swipe and the user collection data might not be present in swipe
Thanks

I have next Django model.
class StocksHistory(models.Model):
wh_data = models.JsonField()
created_at = models.DateTimeField()
I store JSON data in wh_data.
[
{
"id":4124124,
"stocks":[
{
"wh":507,
"qty":2
},
{
"wh":2737,
"qty":1
}
],
},
{
"id":746457457,
"stocks":[
{
"wh":507,
"qty":3
}
]
}
]
Note: it's data for one row - 2022-06-06.
I need to calculate the sum inside stocks by grouping them by wh and by created_at so that the output is something like this
[
{
"wh":507,
"qty":5,
"created_at":"2022-06-06"
},
{
"wh":2737,
"qty":1,
"created_at":"2022-06-06"
},
{
"wh":507,
"qty":0,
"created_at":"2022-06-07"
},
{
"wh":2737,
"qty":2,
"created_at":"2022-06-07"
}
]
I know how to group by date, but I don't understand how to proceed with aggregations inside JsonField.
StocksHistory.objects.extra(select={'day': 'date( created_at )'})
.values('day')
.annotate(
???
)
A solution is suitable, both through Django ORM and through RAW SQL.

I'm new to SQL and MongoDB. I'm trying to convert this:
SELECT accountType, ROUND(AVG(balance), 2) avgBalance
FROM customers
WHERE gender="female"
GROUP BY accountType
HAVING COUNT(*) < 140
ORDER BY avgBalance
LIMIT 1
to MongoDB but I can't get it to work. I don't quite understand how the order ($group, $match, $project, $round, $avg etc.) should be and how the "ROUND and AVG" are used together. This is how the answer should be like: { "accountType" : "account-type", "avgBalance" : NumberDecimal("9999.99") }
Here is what I have so far:
db.customers.aggregate( [ { $group: { _id: { accountType: "accountType", avgBalance: { $avg: { "balance" } } }, { $match: { count: { $lt: 140 } } }, { gender: "female" }, { $project: { "accountType": { $round: [ $agv: "balance", 2 ] } } }, { $limit: 1 } ] )
Direction is not bad, would be this one:
db.customers.aggregate([
// WHERE gender="female"
{ $match: { gender: "female" } },
// GROUP BY accountType, SELECT AVG(balance)
{
$group: {
_id: "$accountType",
avgBalance: { $avg: "$balance" },
count: {$sum: 1}
}
},
// HAVING COUNT(*) < 140
{ $match: { count: { $lt: 140 } } },
// SELECT ... AS ...
{
$project: {
accountType: "$_id",
avgBalance: { $round: ["$avgBalance", 2] }
}
},
// ORDER BY avgBalance
{ $sort: { avgBalance: 1 } },
// LIMIT 1
{ $limit: 1 }
])
SELECT s_name FROM supplier
WHERE s_suppkey = ALL
(SELECT s_suppkey FROM supplier
WHERE s_nationkey > 50 AND s_acctbal= 9658.99 )
I don't know how to do this part
WHERE s_suppkey = ALL
(SELECT s_suppkey FROM supplier
WHERE s_nationkey > 50 AND s_acctbal= 9658.99 )
db.supplier.find( {}, { $and : [ { s_nationkey : { '$gt' : 50 } }, { s_acctbal : 9658.99 } ] } ,{s_suppkey:1} )
But does not return suppliers name!
You SQL looks a bit strange. For Mongo try this one:
db.supplier.find({ s_nationkey: { '$gt': 50 }, s_acctbal: 9658.99 }, {s_name :1} )
The _.uniq() in lodash removes duplicates from an array:
var tst = [
{ "topicId":1,"subTopicId":1,"topicName":"a","subTopicName1":"w" },
{ "topicId":2,"subTopicId":2,"topicName":"b","subTopicName2":"x" },
{ "topicId":3,"subTopicId":3,"topicName":"c","subTopicName3":"y" },
{ "topicId":1,"subTopicId":4,"topicName":"c","subTopicName4":"z" }]
var t = _.uniq(tst, 'topicName')
This returns:
[ {"topicId":1,"subTopicId":1,"topicName":"a","subTopicName1":"w" },
{ topicId: 2, subTopicId: 2, topicName: 'b', subTopicName2: 'x' },
{ topicId: 3, subTopicId: 3, topicName: 'c', subTopicName3: 'y' } ]
What's the opposite of this? It should only return a single object for each duplicate object:
[ { topicId: 3, subTopicId: 3, topicName: 'c', subTopicName3: 'y' } ]
I don't think there's a built in method, here's something that should do the job:
function dupesOnly(arr, field) {
var seen = {},
ret = [];
arr.forEach(function(item) {
var key = item[field],
val = seen[key];
if (!val) {
seen[key] = val = {
initial: item,
count: 0
}
}
if (val.count === 1) {
ret.push(val.initial);
}
++val.count;
});
return ret;
}
In this query i used were clause in that year is 2015 and quarter-[2013]&[Quarter1], how is it possible, and getting result set 10 records. actually result set is not displaying.
WITH MEMBER [Measures].[Test] AS ( [Measures].[ProgramAssessmentPatientCnt] + [Measures].[AssessmentPatientCnt] )
MEMBER [Measures].[Test1] AS ( [Measures].[CCMPatientCnt] + [Measures].[CareteamCnt] + [Measures].[CCMPatientCnt] )
SELECT ( ( { [DimEnrollStatus].[EnrollmentStatus].[EnrollmentStatus] } ),
{ [Measures].[AssessmentPatientCnt], [Measures].[Test], [Measures].[Test1] } ) ON COLUMNS,
Subset (
NonEmpty (
{
( { [DimAssessment].[AssessmentText].[AssessmentText] },
{ [DimAssessment].[QuestionText].[QuestionText] },
{ [DimAssessment].[AnswerText].[AnswerText] } )
},
{ [Measures].[AssessmentPatientCnt], [Measures].[Test], [Measures].[Test1] }
),
0,
10
) ON ROWS
FROM [NavigateCube]
WHERE (
{
( { [DimManagedPopulation].[ManagedPopulationName].&[1044]&[LTC Lincoln Centers] },
{ [DimAnchorDate].[Calender Year].&[2015] },
{ [DimAnchorDate].[Calendar Semester Des].[All] },
{ [DimAnchorDate].[Calendar Quarter Des].&[2013]&[Quarter1] },
{ [DimAnchorDate].[English Month Name Desc].[All] } )
} )
Does this return any rows?
WHERE
(
[DimManagedPopulation].[ManagedPopulationName].&[1044]&[LTC Lincoln Centers],
[DimAnchorDate].[Calender Year].&[2015],
//[DimAnchorDate].[Calendar Semester Des].[All],
[DimAnchorDate].[Calendar Quarter Des].&[2013]&[Quarter1],
[DimAnchorDate].[English Month Name Desc].[All]
);
Maybe the following:
WHERE
(
[DimManagedPopulation].[ManagedPopulationName].&[1044]&[LTC Lincoln Centers],
{
[DimAnchorDate].[Calender Year].&[2015],
[DimAnchorDate].[Calendar Semester Des].[All],
[DimAnchorDate].[Calendar Quarter Des].&[2013]&[Quarter1],
[DimAnchorDate].[English Month Name Desc].[All]
}
);
