To write data to [Snowflake](https://www.snowflake.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**: snowflake
    - **dataSourceName**: _See [data source name](#snowflake-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: "snowflake",
        dataSourceName: "user:password@account/db/exampleschema?warehouse=wh",
        table: "example_table",
    )
```

## Snowflake data source name
The `snowflake` driver uses the following DSN syntaxes (also known as a **connection string**):

```
username[:password]@accountname/dbname/schemaname?param1=value1&paramN=valueN
username[:password]@accountname/dbname?param1=value1&paramN=valueN
username[:password]@hostname:port/dbname/schemaname?account=<your_account>&param1=value1&paramN=valueN
```

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