To query [Vertica](https://www.vertica.com/) with Flux:

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

    - **driverName**: vertica or vertigo
    - **dataSourceName**: _See [data source name](#vertica-data-source-name)_
    - **query**: PSQL query to execute

```js
import "sql"

sql.from(
    driverName: "vertica",
    dataSourceName: "vertica://username:password@localhost:5433/dbname",
    query: "SELECT * FROM public.example_table",
)
```

## Vertica data source name
The `vertica` and `vertigo` drivers use the following DSN syntax (also known as a **connection string**):

```
vertica://<user>:<password>@<host>:<port>/<database>?<queryArgs>
```

The `vertica` and `vertigo` drivers use the `vertica/vertica-sql-go` implementation.
For information about supported DSN query arguments, see the
[`vertica/vertica-sql-go` documentation](https://github.com/vertica/vertica-sql-go#creating-a-connection).

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