I am looking for an implementation example of LaunchInstanceRequest with the SourceDetails field when it is asking for an interface.
instanceRequest := core.LaunchInstanceRequest{}
instanceRequest.SourceDetails = ...
I am referring to the following for documentation.
https://godoc.org/github.com/oracle/oci-go-sdk/core#LaunchInstanceRequest
One such example would be to do the following
var instanceSD core.InstanceSourceDetails = core.InstanceSourceViaImageDetails{
ImageId: common.String("ocid1.image.oc1.iad.aaaaaaaa2tq67tvbeavcmioghquci6p3pvqwbneq3vfy7fe7m7geiga4cnxa"),
BootVolumeSizeInGBs: common.Int64(50),
}
instanceRequest.SourceDetails = instanceSD

I am having some difficulty crafting a query for nested data in cosmosDB.
Say I have data stored in this structure:
{
id:"1234",
data:{
people:{
"a826bbc5-add9-42d8-ba52-f5de52973556":{
first_name: "Kyle"
},
"efb119d-9f12-4d11-a7e1-38e4719a699c":{
first_name: "Bob"
},
"b402faac-d1ba-4317-9ba6-673c76a8fc37":{
first_name: "Jane"
}
}
}
}
Now I want to write a query that would return all of the people with the first name of "Bob"
I need something like:
Select * from c where c.data.people[*].first_name = "Bob";
Notice that the "people" object is an actual JSON object not a JSON array, so no array_contains, I need basically the JSON obj equivalent.
I've looked around and can't seem to find the appropriate query for this common use-case.
Anyone know how I can accomplish this query?
Since the key of people objects is random,i'm afraid you can't query it with normal sql.I tried to implement your needs with UDF in cosmos db.
Udf code:
function userDefinedFunction(peopleObj){
var returnArray = [];
for(var key in peopleObj){
if (peopleObj[key].first_name == "Bob"){
var map = {};
map[key] = peopleObj[key];
returnArray.push(map);
}
}
return returnArray;
}
Sql:
SELECT udf.test(c.data.people) as BobPeople FROM c
Sample data:
Output:
Marked Jay's answer as the accepted answer as I ended up using udfs - I'll post the function I ended up using and the query for anyone looking for something a little more generic.
function userDefinedFunction(properties, fieldName, filedValue){
for(var k in properties){
if(properties[k][fieldName] && properties[k][fieldName] == filedValue)
return true;
}
return false;
}
with a query of:
select * from c where udf.hasValue(c.data.people,"first_name","Bob")
I try to access to my data json file:
[{"id":1,"name":"Maria","project":[{"id":5,"name":"Animals"},{"id":6,"name":"Cats"}]}
This is my approach:
data[0].name;
But like this I get only the result:
Animals
But I would need the result:
Animals, Cats
You are accessing only the name property of 0th index of project array.
To access all object at a time you need to loop over the array.
You can use Array.map for this.
var data = [{"id":1,"name":"Maria","project":[{"id":5,"name":"Animals"},{"id":6,"name":"Cats"}]}]
var out = data[0].project.map(project => project.name).toString()
console.log(out)
If that's your actual data object, then data[0].name would give you "Maria". If I'm reading this right, though, you want to get all the names from the project array. You can use Array.map to do it fairly easily. Note the use of an ES6 arrow function to quickly and easily take in the object and return its name.
var bigObject = [{"id":1,"name":"Maria","project":[{"id":5,"name":"Animals"},{"id":6,"name":"Cats"}]}];
var smallObject = [{"id":5,"name":"Animals"},{"id":6,"name":"Cats"}];
console.log("Getting the names from the full array/data structure: "+bigObject[0].project.map(obj => obj.name))
console.log("Getting the names from just the project array: "+smallObject.map(obj => obj.name))
EDIT: As per your comment on the other answer, you said you needed to use the solution in this function:
"render": function (data, type, row) {if(Array.isArray(data)){return data.name;}}
To achieve this, it looks like you should use my bottom solution of the first snippet like so:
var data = [{"id":5,"name":"Animals"},{"id":6,"name":"Cats"}];
function render(data, type, row){
if(Array.isArray(data)){
return data.map(obj => obj.name);
}
};
console.log("Render returns \""+render(data)+"\" as an array.");
I want to apply SplitJson in order to split the following JSON file into 2 FlowFiles (according to hits):
{"took":0,"timed_out":false,"_shards":
{"total":5,"successful":5,"failed":0},
"hits":{"total":2,"max_score":0.0,
"hits":
[
{"_index":"my_index","_type":"my_entry","_id":"111","_score":0.0,"_source":{"ZoneId":"1","OriginId":"1"},
"fields":{"ttime":[11000]}},
{"_index":"my_index","_type":"my_entry","_id":"222","_score":0.0,"_source":{"ZoneId":"1","OriginId":"2"},
"fields":{"ttime":[5000]}}
]
}
}
Which JsonPath Expression should I use? I tried $.hits[*], but it splits the content according to the first level hits. In my case I have hits[hits[...]], but how should I specify it in the expression?
UPDATE:
I want to get two FlowFiles:
FlowFile #1: {"_index":"my_index","_type":"my_entry","_id":"111","_score":0.0,"_source":{"ZoneId":"1","OriginId":"1"},"fields":{"ttime":[11000]}}
FlowFile #2:
{"_index":"my_index","_type":"my_entry","_id":"222","_score":0.0,"_source":{"ZoneId":"1","OriginId":"2"},"fields":{"ttime":[5000]}}
var arr = $.hits.hits;
Will give you the array with 2 objects you desire.
var o1 = arr[0];
var o2 = arr[1];
Will give you 2 objects you desire.
var json1 = JSON.stringify(arr[0]);
var json2 = JSON.stringify(arr[1]);
Will give you 2 JSON files as requested.
Is this what you needed?
You can use this website for testing JSONPath Index for your case.
The right answer is $.hits.hits[*].
As mentioned DanteTheSmith, you can simply use $.hits.hits in your case. It depends on the post-processing. Both methods work fine.
lets say there is customer object, i need to add new element address to this json object customer. how can I achieve this?
Both of these are not altering the customer JSON object
customer['address'] = addressObj
customer.address = addressObj
and I can not use push() as this is not adding a new item in list of objects.
Thanks,
Naren
Maybe your addressObj is not properly formed.
This works for me:
var customer = {"name": "Naren"};
customer.address1 = "stackoverflow";
customer.address2 = {"fulladdress":"stackoverflow"};
JSON.stringify(customer)
Output:
"{"name":"Naren","address1":"stackoverflow","address2":{"fulladdress":"stackoverflow"}}"
Maybe I am not clear on what exactly you want to do but it sounds to me as if you want have a JSON and want to merge it with another JSON, creating just a JSON file.
let Json1 = {'Superman': 'Favorite' };
let Json2 = {'Supergirl': 'Greatest'};
let Json3 = {'IronFist': 'Top 10' };
You now want to add Supergirl (the new element) to Superman (the old element) I assume. Take a look here # merge-json a simple package which does its job well. You would code as follows:
use strict;
var mergeJSON = require("merge-json");
let Json1 = {'Superman': 'Favorite' };
let Json2 = {'Supergirl': 'Greatest'};
let Json3 = {'IronFist': 'Top 10' };
let Json6 = mergeJSON(Json1,Json2);
Json6=mergeJSON(Json6,Json3);
You would end up with as follows:
Json6 = {'Superman': 'Favorite', 'Supergirl': 'Greatest', 'IronFist': 'Top 10'}
This is how I make use of combining JSON information or text information into a JSON file. You can get much more sophisticated with the module mentioned above. (Just do not confuse merge-json with json-merge and other modules.)
If this is not what you are looking for my apologies, then I did not understand the question correctly.
I develop web application with golang.
I use the library gocraft/dbr as O/R Mapper.
I have two tables: image and entry.
I join their tables and I want to get image_url.
type Image struct {
ImageUrl dbr.NullString `db:"image_url"`
}
type Entry struct {
CompanyImageID dbr.NullInt64 `db:"company_image_id"`
CompanyImage Image
EyecatchIamgeID dbr.NullInt64 `db:"eyecatch_image_id"`
EyecatchImage Image
}
Then I tried below:
var entry Entry
sess.Select("*").From("entry").
LeftJoin(dbr.I("image").As("eyecatch_image"), "entry.eyecatch_image_id = eyecatch_image.id").
LeftJoin(dbr.I("image").As("company_image"), "entry.company_image_id = company_image.id").
Load(&entry)
log.Println("company:", entry.CompanyImage)
log.Println("eyecatch:", entry.EyecatchImage)
result:
company: {{{https://company_image_url.png true}}}
eyecatch: {{{ false}}}
I expect below, but it did not become as expected.
company: {{{https://company_image_url.png true}}}
eyecatch: {{{{http://eyecatch_image_url.png true}}}
When I tried to change join condition like below:
sess.Select("*").From("entry").
LeftJoin(dbr.I("image").As("eyecatch_image"), "entry.eyecatch_image_id = eyecatch_image.id")
Load(&entry)
result:
company: {{{http://eyecatch_image_url.png true}}}
eyecatch: {{{ false}} {{ false}}}}
I don't know how to use join with multiple conditions.
Thank you.
The documentation is really poor - it seems they gave up on the idea of publishing the library. There is an open pull request that provides a little better documentation.. Here the author describes that you can create a multiple condition like this:
cond:= dbr.And(
dbr.Or(
dbr.Gt("created_at", "2015-09-10"),
dbr.Lte("created_at", "2015-09-11"),
),
dbr.Eq("title", "hello world"),
)
Then use the condition in any statement:
sess.Select("*").From("entry").
LeftJoin(dbr.I("image").As("eyecatch_image"), cond)
Load(&entry)
