package gcpmysql

import "gocloud.dev/mysql/gcpmysql"

Package gcpmysql provides connections to managed MySQL Cloud SQL instances. See https://cloud.google.com/sql/docs/mysql/ for more information.

URLs

For mysql.Open, gcpmysql registers for the scheme "gcpmysql". The default URL opener will create a connection using the default credentials from the environment, as described in https://cloud.google.com/docs/authentication/production. To customize the URL opener, or for more details on the URL format, see URLOpener.

See https://gocloud.dev/concepts/urls/ for background information.

	"context"
	"log"

	"gocloud.dev/mysql"

func main() {
	// PRAGMA: This example is used on gocloud.dev; PRAGMA comments adjust how it is shown and can be ignored.

	// PRAGMA: On gocloud.dev, hide lines until the next blank line.

	// Replace this with your actual settings.
	db, err := mysql.Open(ctx,
		"gcpmysql://user:password@example-project/region/my-instance01/testdb")
