# Query MySQL

To query [MySQL](https://www.mysql.com/) with Flux:

1. Import the [`sql` package](/flux/v0/stdlib/sql/).
    
2. Use [`sql.from()`](/flux/v0/stdlib/sql/from/) and provide the following parameters:
    
    -   **driverName**: mysql
    -   **dataSourceName**: *See [data source name](#mysql-data-source-name)*
    -   **query**: SQL query to execute

```js
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
```

## MySQL to Flux data type conversion

`sql.from()` converts MySQL data types to Flux data types.

| MySQL data type | Flux data type |
| --- | --- |
| INT, BIGINT, SMALLINT, TINYINT | int |
| FLOAT, DOUBLE | float |
| DATETIME | time |
| STRING | string |

All other MySQL data types are converted to strings.
