2. Use the [`sql.from()` function](/flux/v0/stdlib/sql/from/) and provide the
  following parameters:

    - **driverName**: _Determined by your [Amazon RDS database engine](#supported-database-engines)_
    - **dataSourceName**: _Determined by your [Amazon RDS database engine](#supported-database-engines)_
    - **query**: SQL query to execute
