I am new to graphql and have a simple query returning results. i then want to loop the retuned results and run another query. I am after the data returned from the second query.
1st query
{
queryOne (where: {deployer: "id"}) {
id
...
state {
constants
}
}
constants will contain an array of 2 rows. which i can ref as result.data.state.constants[0] and result.data.state.constants[1]. On these 2 I would like to run the following
queryTwo (where: {id: result.data.state.constants[0]}) {
id
...
}

I have built this query to request data from the Pokeapi graphQL server here
https://beta.pokeapi.co/graphql/console/
query getPokemon (
$typesList: [Int!],
) {
pokemon_v2_pokemon(
where: {
pokemon_v2_pokemontypes: { type_id: { _in: $typesList } }
}
) {
id
name
pokemon_v2_pokemontypes {
type_id
pokemon_v2_type {
name
}
}
}
}
How can I modify the query to return all results when the $typesList list is empty? I would like the query to return a filtered results list when $typesList has a list of ids, but it should return all values when the $typesList list is empty.
Is this something that is possible in graphQL?
Thank you
If you controlled the server you could write the resolver to function in the manner you're looking for but since you don't your only option is to wrap your use of the query with something that sets the default typesList variable to all possible types.
I have a graphQL server consumed by many clients and have a process that generates operations from introspection; problem is that the schema has a handful of nested queries that take arguments that I may or may not want to invoke.
given this generated operation
query Query($input: String!) {
things(input: $input) {
item1
item2
nestedQuery(nestedInput: $nestedInput) {
nestedItem1
}
}
}
is there a tool (other than string parsing, that's a given) to strip unwanted fields from here so that the query is transformed into
query Query($input: String!) {
things(input: $input) {
item1
item2
}
}
Looking at the introspection JSON I can identify this item by the presence of args on the field things that is past the first depth - but I don't want to necessarily lose information on generation - I'd like those nested queries to be visible/documented.
I still don't understand how you are generating the GraphQL document here, but assuming that you have total control over it, you can use the default directives (#skip and #include) to skip or include fields based on a condition.
For example, the following document will skip the nestedQuery field when executing. You may use a variable value as the value for the argument if.
query Query($input: String!) {
things(input: $input) {
item1
item2
nestedQuery(nestedInput: $nestedInput) #skip(if: true) {
nestedItem1
}
}
}
So I'm trying to learn graphql I've been playing around with the ENS subgraph on the graph
I've figured out how to do simple filtering but when I try to write more complex filters they do not compile.
I'm trying to get the top 5 transactions for the each of the top 5 domains. (e.g for each domain I want the top 5 transactions)
{
#Sample Query to get the first 5 domains (not needed for question but used to validate results)
domains(first: 5) {
id
name
labelName
labelhash
}
#attempt to filter the transfer.domain.id by TOP 5 domains.id
transfers(where: { domain { id: domains(first: 5) { id } } }) {
id
domain {
id
}
blockNumber
transactionID
}
}
EDIT I'm going to attempt to simplify my request since I'm not sure nesting queries is possible. How can I filter an inner query by Id:
transfers(where: {domain.id: "0x9c0fc2519ae862cee27778e5c34714d6c7e3ca21ad572df47ad9f6fe530909bd"}) {
id
domain {
id
}
blockNumber
transactionID
}
NOTE: Domain.Id = does not compile how would I write a filtered query like that?
However, My filter doesn't compile syntactically. How can I write a query which filters by a child property?
You can query like this
query {
getPost(id: "0x1") {
title
text
datePublished
}
}
Got this from https://dgraph.io/docs/graphql/queries/search-filtering/
I am new to GraphQL. I know this is a basic question but hope someone could help me to add variables to my query as I tried many times and failed :(
In my query, below schema is used:
type Query {
ContinentInfo(id: ID): Continent
}
type Continent {
id : ID
name: String
countries: [Country]
}
type Country {
id : ID
name : String
population: Float
}
Below query is executed successfully:
{
ContinentInfo(id: "continent01") {
name
countries {
name
population
}
}
}
Then I want to add more conditions in the query, for example add a variable "populationMoreThan" to filter the result. so the query may look like:
{
ContinentInfo(id: "continent01") {
name
countries(populationMoreThan: $populationMoreThan) {
name
population
}
}
}
but it always failed when I tried to add this variable in the schema and in the query.
Could anyone provide me an example of adding variable in my case?
Also, it looks I need to pass the parameter value into the query? Now I'm using graphql.GraphQL.execute(queryString) to pass the query string. How to pass the variable value here?
Finally found a way to filter the result.
Update the schema with:
type Continent {
id : ID
name: String
countries(populationMoreThan: Float = 0): [Country]
}
And query with:
{
ContinentInfo(id: "continent01") {
name
countries(populationMoreThan: 1.0) {
name
population
}
}
}
I have this mongo query (java):
TextQuery.queryText(textCriteria).sortByScore().limit(configuration.getSearchResultSize())
which performs a text search and sort by score.
I gave different wiehgt to different fields in the docuemnt, and now I'd like to retrieve only those results with score lower then 10.
is there a way to add that criteria to the query?
this didn't work:
query.addCriteria(Criteria.where("score").lt(10));
if the only way is to use aggregation - I need a mongoTemplate example for that.
in other words
how the do I translate the following mongo shell aggregate command, to java spring's mongoTemplate command??
can't find anywhere how to use the aggregate's match() API with the $text search component (the $text is indexed on several different fields):
db.text.aggregate(
[
{ $match: { $text: { $search: "read" } } },
{ $project: { title: 1, score: { $meta: "textScore" } } },
{ $match: { score: { $lt: 10.0 } } }
]
)
Thanks!
Please check with below code sample, MongoDB search with pagination code in java
BasicDBObject query = new BasicDBObject()
query.put(column_name, new BasicDBObject("$regex", searchString).append("$options", "i"));
DBCursor cursor = dbCollection.find(query);
cursor.skip((pageNum-1)*limit);
cursor.limit(limit);
Write a loop and and call the above code from loop and pass the values like pageNum starts from 1 to n and limit depends on your requirement. check the cursor is empty or not. If empty skip the loop if not continue calling the above code base.
Hope this will be helpful.
