# Query Amazon RDS

To query a relational database hosted on [Amazon Relational Database Service (RDS)](https://aws.amazon.com/rds/) with Flux:

1. Import the [`sql` package](/flux/v0/stdlib/sql/)
    
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

    query: "SELECT * FROM example_table",
)
```
