How to pass query statement to bigquery in node.js environment - node.js

Question

During the big query, the parameters of the function in the SQL statement
I want to update the result of a sql statement by inserting it as # variable name.
However, there is no method to support node.js.
For python, there are methods like the following example.
You can use the function's parameters as # variable names.
query = "" "
SELECT word, word_count
FROM `bigquery-public-data.samples.shakespeare`
WHERE corpus = # corpus
AND word_count> = #min_word_count
ORDER BY word_count DESC;"" "
query_params = [
bigquery.ScalarQueryParameter ('corpus', 'STRING', 'romeoandjuliet'),
bigquery.ScalarQueryParameter ('min_word_count', 'INT64', 250)]
job_config = bigquery.QueryJobConfig ()
job_config.query_parameters = query_params

I would like to ask for advice.

Answer 1

BigQuery node.js client supports parameterized queries when you pass them with the params key in options. Just updated the docs to show this. Hope this helps!
Example:
const sqlQuery = `SELECT word, word_count
FROM \`bigquery-public-data.samples.shakespeare\`
WHERE corpus = #corpus
AND word_count >= #min_word_count
ORDER BY word_count DESC`;
const options = {
query: sqlQuery,
// Location must match that of the dataset(s) referenced in the query.
location: 'US',
params: {corpus: 'romeoandjuliet', min_word_count: 250},
};
// Run the query
const [rows] = await bigquery.query(options);

let ip_chunk = "'1.2.3.4', '2.3.4.5', '10.20.30.40'"
let query = `
SELECT
ip_address.ip as ip,
instance.zone as zone,
instance.name as vmName,
instance.p_name as projectName
FROM
\`${projectId}.${datasetId}.${tableId}\` instance,
UNNEST(field_x.DATA.some_info) ip_address
WHERE ip_address.networkIP IN (${ip_chunk})`
**Use - WHERE ip_address.networkIP in (${ip_chunk})
instead of - WHERE ip in (${ip_chunk})**

It is worth adding that you can create a stored procedure and pass parameters the same way as the accepted answer shows.
const { BigQuery } = require('#google-cloud/bigquery');
function testProc() {
return new Promise((resolve) => {
const bigquery = new BigQuery();
const sql = "CALL `my-project.my-dataset.getWeather`(#dt);";
const options = {
query: sql,
params: {dt: '2022-09-01'},
location: 'US'
};
// Run the query
const result = bigquery.query(options);
return result.then((rows) => {
console.log(rows);
resolve(rows);
});
});
}
testProc().catch((err) => { console.error(JSON.stringify(helpers.getError(err.message))); });
