I have a table that looks like this:
id
json_col
35
[{"key_one":4,"key_two":{"value":1,"type":"static"}},{"key_one":27,"key_two":{"value":26,"type":"dynamic"}}]
36
[{"key_one":2,"key_two":{"value":33,"type":"static"}},{"key_one":9,"key_two":{"value":1,"type":"any"}}]
[
{
"id": 35,
"json_col": [
{
"key_one": 4,
"key_two": {
"value": 1,
"type": "static"
}
},
{
"key_one": 27,
"key_two": {
"value": 26,
"type": "dynamic"
}
}
],
"created_at": "2023-02-13T16:54:13.000000Z",
"updated_at": "2023-02-13T16:54:13.000000Z"
},
{
"id": 36,
"json_col": [
{
"key_one": 2,
"key_two": {
"value": 33,
"type": "static"
}
},
{
"key_one": 9,
"key_two": {
"value": 1,
"type": "any"
}
}
],
"created_at": "2023-02-13T16:54:56.000000Z",
"updated_at": "2023-02-13T16:54:56.000000Z"
}
]
How to get the row 35 that has key_two with value = 1 and type = static, using the query builder or a raw query?
you can use whereJsonContains with multi-dimentional array base on how you store them.
return Model::whereJsonContains('json_col', [ ['key_two' => [ 'value' => 1] ] ])
->whereJsonContains('json_col', [ ['key_two' => [ 'type' => 'static'] ] ])
->paginate(10); // or get()
just double check the sql output actually looks like your json format which should look something like
WHERE json_contains(`json_col`, '[{\"key_two\":{\"value\":1}}]')
AND json_contains(`json_col`, '[{\"key_two\":{\"type\":\"static\"}}]')
EDIT
If you need to search multiple match in single object, then this should do
return Model::whereJsonContains('json_col', [ ['key_two' => [ 'value' => 1, 'type' => 'static' ] ] ])
->paginate(10); // or get()

And i try something like this but dont work
.where(qb => {
if (nbMusicians) {
qb.whereRaw(

Thanks for help
I have a jsonb column called data in a table called reports. Here is what report.id = 1 looks like
[
{
"Product": [
{
"productIDs": [
"ABC1",
"ABC2"
],
"groupID": "Food123"
},
{
"productIDs": [
"EFG1"
],
"groupID": "Electronic123"
}
],
"Package": [
{
"groupID": "Electronic123"
}
],
"type": "Produce"
},
{
"Product": [
{
"productIDs": [
"ABC1",
"ABC2"
],
"groupID": "Clothes123"
}
],
"Package": [
{
"groupID": "Food123"
}
],
"type": "Wearables"
}
]
and here is what report.id = 2 looks like:
[
{
"Product": [
{
"productIDs": [
"XYZ1",
"XYZ2"
],
"groupID": "Food123"
}
],
"Package": [],
"type": "Wearable"
},
{
"Product": [
{
"productIDs": [
"ABC1",
"ABC2"
],
"groupID": "Clothes123"
}
],
"Package": [
{
"groupID": "Food123"
}
],
"type": "Wearables"
}
]
I am trying to get a list of all entries in reports table where at least one of data column's element has following:
type = Produce AND
where any elements of Product array OR any elements of Product array's groupID start with Food
So from the example above this query will only return the first index since
The type = Produce
groupID starts with Food for first element of Product array
The second index will be filtered out because type is not Produce.
I am not sure how to query to do AND query for groupID. Here is what I have tried to get all entries for type Produce
select * from reports r, jsonb_to_recordset(r.data) as items(type text) where items.type like 'Produce';
Sample structure and result: dbfiddle
select r.*
from reports r
cross join jsonb_array_elements(r.data) l1
cross join jsonb_array_elements(l1.value -> 'Product') l2
where l1 ->> 'type' = 'Produce'
and l2.value ->> 'groupID' ~ '^Food';
I am using Cosmos DB and have a document with the following simplified structure:
{
"id1":"123",
"stuff": [
{
"id2": "stuff",
"a": {
"b": {
"c": {
"d": [
{
"e": [
{
"id3": "things",
"name": "animals",
"classes": [
{
"name": "ostrich",
"meta": 1
},
{
"name": "big ostrich",
"meta": 1
}
]
},
{
"id3": "default",
"name": "other",
"classes": [
{
"name": "green trees",
"meta": 1
},
{
"name": "trees",
"score": 1
}
]
}
]
}
]
}
}
}
}
]
}
My issue is - I have an array of these documents and need to search name to see if it matches my search word. For example I want both big trees and trees to return if a user types in trees.
So currently I push every document into an array and do the following:
For each document
for each stuff
for each a.b.c.d[0].e
for each classes
var splice = name.split(' ')
if (splice.includes(searchWord))
return id1, id2 and id3.
Using cosmosDB I am using SQL with the following code:
client.queryDocuments(
collection,
`SELECT * FROM root r`
).toArray((err, results) => {stuff});
This effectively brings every document in my collection into an array to perform the search manually above as mentioned.
This is going to cause issues when I have 1000s or 1,000,000s of documents in the array and I believe I should be leveraging the search mechanics available within Cosmos itself. Is anyone able to help me to work out what SQL query would be able to perform this type of function?
Having searched everything is it also possible to search the 5 latest documents?
Thanks for any insight in advance!

According to your sample and description, I suggest you using ARRAY_CONTAINS in cosmos db sql. Please refer to my sample:

2.Having searched everything is it also possible to search the 5 latest

Per my research, features like LIMIT is not supported in cosmos so far. However , TOP is supported by cosmos db. So if you could add sort field(such as date or id), then you could use sql:
select top 5 from c order by c.sort desc
I have json data similar to this:
{
"Sections": [
{
"Categories": [
{
"Name": "Book",
"Id": 1,
"Options": [
{
"Name": "AAAA",
"OptionId": 111
},
"Selected": 0
},
{
"Name": "Car",
"Id": 2,
"Options": [
{
"Name": "BBB",
"OptionId": 222
},
"Selected": 0
},
],
"SectionName": "Main"
},
... more sections like the one above
]
}
Given this data, I want to find a category inside a section based on its (Category) Id, and set its selected option, I tried this, but couldn't get it to work....Note Category Id will be unique in the whole data set.
_.find(model.Sections, { Categories: [ { Id: catId } ]});
According to your data model, it looks like you're trying to find an element that is inside a matrix: Sections can have multiple Categories and a Category can have multiple types (car, book...).
I'm afraid there isn't a function in lodash that allows a deep find, you'll have to implement it the 'traditional' way (a couple of fors).
I provide this solution that is a bit more 'functional flavoured' than the traditional nested fors. It also takes advantage of the fact that when you explicitly return false inside a forEach, the loop finishes. Thus, once an element with the provided id is found, the loop is ended and the element returned (if it's not found, undefined is returned instead).
Hope it helps.
const findCategoryById = (sections, id) => {
var category;
_.forEach(sections, (section) => {
category = _.find(section.Categories, ['Id', id]);
return _.isUndefined(category);
});
return category;
};
const ex = {
"Sections": [{
"Categories": [{
"Name": "Book",
"Id": 1,
"Options": [{
"Name": "AAAA",
"OptionId": 111
}],
"Selected": 0
},
{
"Name": "Car",
"Id": 2,
"Options": [{
"Name": "BBB",
"OptionId": 222
}],
"Selected": 0
}
],
"SectionName": "Main"
}]
};
console.log(findCategoryById(ex.Sections, 2));

I'm new in lodash (v3.10.1), and having a hard time understanding.
Hope someone can help.
I have an input something like this:
{
{"id":1,"name":"Matthew","company":{"id":1,"name":"abc","industry":{"id":5,"name":"Medical"}}},
{"id":2,"name":"Mark","company":{"id":1,"name":"abc","industry":{"id":5,"name":"Medical"}}},
{"id":3,"name":"Luke","company":{"id":1,"name":"abc","industry":{"id":5,"name":"Medical"}}},
{"id":4,"name":"John","company":{"id":1,"name":"abc","industry":{"id":5,"name":"Medical"}}},
{"id":5,"name":"Paul","company":{"id":1,"name":"abc","industry":{"id":5,"name":"Medical"}}}
];
I would like to output this or close to this:
{
"industries": [
{
"industry":{
"id":5,
"name":"Medical",
"companies": [
{
"company":{
"id":1,
"name":"abc",
"employees": [
{"id":1,"name":"Matthew"},
{"id":2,"name":"Mark"},
{"id":3,"name":"Luke"},
{"id":4,"name":"John"},
{"id":5,"name":"Paul"}
]
}
}
]
}
}
]
}
Here's something that gets you close to what you want. I structured the output to be an object instead of an array. You don't need the industries or industry properties in your example output. The output structure looks like this:
{
"industry name": {
"id": "id of industry",
"companies": [
{
"company name": "name of company",
"id": "id of company",
"employees": [
{
"id": "id of company",
"name": "name of employee"
}
]
}
]
}
}
I use the _.chain function to wrap the collection with a lodash wrapper object. This enables me to explicitly chain lodash functions.
From there, I use the _.groupBy function to group elements of the collection by their industry name. Since I'm chaining, I don't have to pass in the array again to the function. It's implicitly passed via the lodash wrapper. The second argument of the _.groupBy is the path to the value I want to group elements by. In this case, it's the path to the industry name: company.industry.name. _.groupBy returns an object with each employee grouped by their industry (industries are keys for this object).
I then do use _.transform to transform each industry object. _.transform is essentially _.reduce except that the results returned from the _.transform function is always an object.
The function passed to the _.transform function gets executed against each key/value pair in the object. In the function, I use _.groupBy again to group employees by company. Based off the results of _.groupBy, I map the values to the final structure I want for each employee object.
I then call the _.value function because I want to unwrap the output collection from the lodash wrapper object.
I hope this made sense. If it doesn't, I highly recommend reading Lo-Dash Essentials. After reading the book, I finally got why lodash is so useful.
"use strict";
var _ = require('lodash');
var emps = [
{ "id": 1, "name": "Matthew", "company": { "id": 1, "name": "abc", "industry": { "id": 5, "name": "Medical" } } },
{ "id": 2, "name": "Mark", "company": { "id": 1, "name": "abc", "industry": { "id": 5, "name": "Medical" } } },
{ "id": 3, "name": "Luke", "company": { "id": 1, "name": "abc", "industry": { "id": 5, "name": "Medical" } } },
{ "id": 4, "name": "John", "company": { "id": 1, "name": "abc", "industry": { "id": 5, "name": "Medical" } } },
{ "id": 5, "name": "Paul", "company": { "id": 1, "name": "abc", "industry": { "id": 5, "name": "Medical" } } }
];
var result = _.chain(emps)
.groupBy("company.industry.name")
.transform(function(result, employees, industry) {
result[industry] = {};
result[industry].id = _.get(employees[0], "company.industry.id");
result[ industry ][ 'companies' ] = _.map(_.groupBy(employees, "company.name"), function( employees, company ) {
return {
company: company,
id: _.get(employees[ 0 ], 'company.id'),
employees: _.map(employees, _.partialRight(_.pick, [ 'id', 'name' ]))
};
});
return result;
})
.value();
Results from your example are as follows:
{
"Medical": {
"id": 5,
"companies": [
{
"company": "abc",
"id": 1,
"employees": [
{
"id": 1,
"name": "Matthew"
},
{
"id": 2,
"name": "Mark"
},
{
"id": 3,
"name": "Luke"
},
{
"id": 4,
"name": "John"
},
{
"id": 5,
"name": "Paul"
}
]
}
]
}
}
If you ever wanted the exact same structure as in the questions, I solved it using the jsonata library:
(
/* lets flatten it out for ease of accessing the properties*/
$step1 := $ ~> | $ |
{
"employee_id": id,
"employee_name": name,
"company_id": company.id,
"company_name": company.name,
"industry_id": company.industry.id,
"industry_name": company.industry.name
},
["company", "id", "name"] |;
/* now the magic begins*/
$step2 := {
"industries":
[($step1{
"industry" & $string(industry_id): ${
"id": $distinct(industry_id)#$I,
"name": $distinct(industry_name),
"companies": [({
"company" & $string(company_id): {
"id": $distinct(company_id),
"name": $distinct(company_name),
"employees": [$.{
"id": $distinct(employee_id),
"name": $distinct(employee_name)
}]
}
} ~> $each(function($v){ {"company": $v} }))]
}
} ~> $each(function($v){ {"industry": $v} }))]
};
)
You can see it in action on the live demo site: https://try.jsonata.org/VvW4uTRz_
