maybe you can help me find out a query. I do a query Like
$Customers = Customer::paginate();
return response()->json([$Customers]);
this returns (just part of response)
[
{
"current_page": 1,
"data": [{"id": 1,}]
}
]
If I do join with other table all data is just put into "data" output. What I want is this for my join: How to get this output??
[
{
"current_page": 1,
"data": [{
"id": 1,
"join": [{ "join_column" : 1 }],
}]
}
]

This is in relation to this question. I'm having this error:
TypeError
Illuminate\Database\Grammar::parameterize(): Argument #1 ($values) must be of type array, int given, called in /var/www/html/vendor/laravel/framework/src/Illuminate/Database/Query/Grammars/Grammar.php on line 920
While inserting data using createMany. This is the form request data:
{
"name": "My Order",
"orders": [
{
"date": "2022-05-17",
"product_id": [1],
"price": 1
},
{
"start_date": "2022-05-18",
"product_id": [2],
"price": 2
}
]
}
This is the store method:
$order = auth()->user()->orders()->create($request->validated());
$order_subs = $order->subOrders()->createMany($request->orders);
$order_sub_items = $request->only('orders')['orders'];
foreach ($order_subs as $key => $value) {
$value->subOrderProducts()->createMany([$order_sub_items[$key]);
}
However, if the product_id is not an array, it will store properly. Sample form request data:
{
"name": "My Order",
"orders": [
{
"date": "2022-05-17",
"product_id": 1,
"price": 1
},
{
"start_date": "2022-05-18",
"product_id": 2,
"price": 2
}
]
}
How to fix this error?
i am having an observable which returns something like this:
"#odata.context": "here is the context URL",
"value": [
{
"Id": 1,
"Value": "A"
},
{
"Id": 2,
"Value": "B"
},
{
"Id": 3,
"Value": "C"
},
{
"Id": 4,
"Value": "A"
}
]
}
Using RxJS i would like to get into the "value" property and use distinct on it to limit the response to something like this:
"#odata.context": "here is the context URL",
"value": [
{
"Id": 1,
"Value": "A"
},
{
"Id": 2,
"Value": "B"
},
{
"Id": 3,
"Value": "C"
}
]
}
could you help me with it?
It pretty much depends on how exactly you want to use this RxJS chain but I hope this leads you the right direction:
const source = of(data)
.pipe(
mergeMap(d => d.value),
distinct(v => v.Value),
toArray(),
)
.subscribe(console.log);
mergeMap will reiterate the array of values as separate emissions where distinct will ignore duplicate Values. Then toArray() will just collect all results.

Query:
SELECT value FROM test.json_test FORMAT JSON
Response:
{
"meta":
[
{
"name": "value",
"type": "Int32"
}
],
"data":
[
{
"value": 1
}
],
"rows": 1,
"statistics":
{
"elapsed": 0.112135109,
"rows_read": 1,
"bytes_read": 4
}
}
How to exclude unnecessary fields and leave only data field?
You can exclude "statistics" from output:
set output_format_write_statistics=0;
ubuntu-16gb-nbg1-1 :) select 1 format JSON;
SELECT 1
FORMAT JSON
{
"meta":
[
{
"name": "1",
"type": "UInt8"
}
],
"data":
[
{
"1": 1
}
],
"rows": 1
}
1 rows in set. Elapsed: 0.003 sec.
It looks like JSONEachRow cannot be used straightforward because the result JSON is not valid.
You can play with grouping data to the array to get valid JSON:
SELECT
groupArray(value) AS values,
groupArray((value, name)) AS objects
FROM
(
SELECT
1 AS value,
'str1' AS name
UNION ALL
SELECT
2 AS value,
'str2' AS name
)
FORMAT JSONEachRow
/* Result:
{"values":[1,2],"objects":[[1,"str1"],[2,"str2"]]}
*/
where you try running your query?
maybe you can try filter this output via pipelines and JQ
clickhouse-client -q "SELECT value FROM test.json_test FORMAT JSON" | jq .data
I'm quite new to Laravel,
Let's say I have 2 tables: main_sport and sub_sport. These two tables have a one-to-many relationship. 1 sport can have many sub sports.
I want the following json format
{
"success": "1",
"sports": [
"id": 1,
"name_of_categories": "Popular Sports",
"sub_sports:[
{
"id": 1,
"name_sub_sport_category": "Badminton"
},
{
"id": 2,
"name_sub_sport_category": "Football"
},
{
"id": 3,
"name_sub_sport_category": "Cricket"
},
]
]
"sports":[
"id": 2,
"name_of_categories": "Team Sports",
"sub_sports:[
{
"id": 4,
"name_sub_sport_category": "Badminton"
},
{
"id": 5,
"name_sub_sport_category": "Football"
},
]
]
}
I try for this function and i am getting following result
public function fetch()
{
$query= DB::table('details')
->join('table_sub_sport_category','table_sub_sport_category.id','=','details.sub_id')
->join('table_main_sport_category','table_main_sport_category.id','=','details.main_id')
->select(DB::raw('table_main_sport_category.id as id'),'table_main_sport_category.name_of_categories','table_sub_sport_category.name_sub_sport_category')
->get()
return response()->json(['success' =>'1','data'=>$query]);
}
{
"success": "1",
"data": [
{
"id": 1,
"name_of_categories": "Popular Sports",
"name_sub_sport_category": "Badminton"
},
{
"id": 1,
"name_of_categories": "Popular Sports",
"name_sub_sport_category": "Football"
},
{
"id": 1,
"name_of_categories": "Popular Sports",
"name_sub_sport_category": "Cricket"
},
]
}
Could you help me to get the desired result?
You should define sub_sport in the main sport Model like this:
class Sport extends Model{
public function sub_sport(){
return $this->hasMany(SubSport::class);
}
}
And in your controller you should write this:
$data = Sport::with('sub_sport')->get();
Use below code
$query= DB::table('details')
->join('table_sub_sport_category','table_sub_sport_category.id','=','details.sub_id')
->join('table_main_sport_category','table_main_sport_category.id','=','details.main_id')
->select(DB::raw('table_main_sport_category.id as id'),'table_main_sport_category.name_of_categories','table_sub_sport_category.name_sub_sport_category')
->get()
return Response::json([
'status' => 'error',
'sports' => $query
], 200);
I have a table that looks like this:
[
{ "name": "Alpha", "values": {
"someProperty": 1
}},
{ "name": "Beta", "values": {
"someProperty": 2
}},
{ "name": "Gamma", "values": {
"someProperty": 3
}}
]
I want to select all records where someProperty is not in some array of values (e.g., all records where someProperty not in [1, 2]). I want to get back complete records, not just the values of someProperty.
How should I do this with RethinkDB?
In python it would be:
table.filter(lambda doc: r.not(r.expr([1,2]).contains(doc["someProperty"]))
If the array comes from a subquery and you don't want to do it multiple times:
subquery.do(lambda array:
table.filter(lambda doc: r.not(array.contains(doc["someProperty"]))))
