To query [MariaDB](https://mariadb.org/) 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](#mariadb-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",
)
```

## MariaDB 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
```

## MariaDB to Flux data type conversion
`sql.from()` converts MariaDB data types to Flux data types.

| MariaDB data type              | Flux data type                                |
| :----------------------------- | :-------------------------------------------- |
| INT, BIGINT, SMALLINT, TINYINT | [int](/flux/v0/data-types/basic/int/)       |
| FLOAT, DOUBLE                  | [float](/flux/v0/data-types/basic/float/)   |
| DATETIME                       | [time](/flux/v0/data-types/basic/time/)     |
| STRING                         | [string](/flux/v0/data-types/basic/string/) |
