Google Cloud SQL - Start Database Instance

See more Google Cloud SQL Examples

Demonstrates how to start a Google Cloud SQL database instance. Rust

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// In this example, Get Google Cloud SQL OAuth2 Access Token, 
// the service account access token was saved to a text file.  This example fetches the access token from the file..

// Implements the following CURL command:

// curl -X PATCH \
// -H "Authorization: Bearer "$(gcloud auth print-access-token) \
// -H "Content-Type: application/json; charset=utf-8" \
// -d '{
