Query MySQL - Influxdb

To query MySQL with Flux:

Import the sql package.
Use sql.from() and provide the following parameters:
- driverName: mysql
- dataSourceName: See data source name
- query: SQL query to execute

import "sql"

sql.from(
    driverName: "mysql",
    dataSourceName: "user:password@tcp(localhost:3306)/db",
    query: "SELECT * FROM example_table",
)

MySQL data source name

The mysql driver uses the following data source name (DSN) syntax (also known as a connection string):

username:password@tcp(localhost:3306)/dbname?param=value
