I want to explain how to use the "IN" search in Node.js.
I understand that the "IN" operator may not be supported in Node.js.
https://cloud.google.com/datastore/docs/concepts/queries#in
Someone help me.
Here is the code I tried.
const idList = [1, 2, 3];
const query = this.dataStoreClient.createQuery('namespace', 'kind')
.filter('ID', 'in', idList);
An error message appeared here, for sure.
Error: 3 INVALID_ARGUMENT: a property filter must specify an operator
As per this reference- https://cloud.google.com/nodejs/docs/reference/datastore/latest/datastore/query
But you check the link- https://cloud.google.com/datastore/docs/concepts/queries#datastore-datastore-property-filter-nodejs
IN comparison operator we can use.
Below is an example of how to use "IN" queries in Node.js with Google Cloud Datastore:
// Import the Google Cloud Datastore client
const Datastore = require('@google-cloud/datastore');
// Create an instance of a Datastore client
const datastore = new Datastore();
// Create an array of the values you want to query
const ids = [1, 2, 3, 4, 5];
// Create a query
const query = datastore
.createQuery('YourEntityName')
.filter('id', 'IN', ids);
// Run the query
datastore.runQuery(query).then(results => {
const entities = results[0];
console.log('Entities:');
entities.forEach(entity => {
console.log(entity);
});
});
