To write data to [Vertica](https://www.vertica.com/) with Flux:

1. Import the [`sql` package](/flux/v0/stdlib/sql/).
2. Pipe-forward data into [`sql.to()`](/flux/v0/stdlib/sql/to/) and provide
   the following parameters:

    - **driverName**: vertica or vertigo
    - **dataSourceName**: _See [data source name](#vertica-data-source-name)_
    - **table**: Table to write to
    - **batchSize**: Number of parameters or columns that can be queued within
      each call to `Exec` (default is `10000`)

```js
import "sql"

data
    |> sql.to(
        driverName: "vertica",
        dataSourceName: "vertica://username:password@localhost:5433/dbname",
        table: "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).

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