ParameterizedQuery

ParameterizedQuery

This is an example how to query with query parameters in InfluxDB Cloud (no support in InfluxDB OSS).

Prerequisites:

• Cloned examples:

  git clone [email protected]:influxdata/influxdb-client-swift.git
  cd Examples/ParameterizedQuery

Sources:

• Package.swift
• ParameterizedQuery.swift

How to test:

1. Start InfluxDB cloud

2. Get Url and Organization name - @url, @org

3. Create bucket - @bucketName

4. Generate API token - @apiToken

5. Start SwiftCLI by:

    docker run --rm \
      --link influxdb_v2 \
      --privileged \
      --interactive \
      --tty \
      --volume $PWD/../..:/client \
      --workdir /client/Examples/ParameterizedQuery \
      swift:5.7 /bin/bash

6. Execute Query by:

   swift run parameterized-query --org @org --bucket @bucketName --token @apiToken --url @url

Expected output

Query to execute:

from(bucket: params.bucketParam)
    |> range(start: -10m)
    |> filter(fn: (r) => r["_measurement"] == params.measurement)

["measurement": "demo", "bucketParam": "my-bucket"]

Success response...

 > value: 2
 > value: 3
