To write data to [SAP HANA](https://www.sap.com/products/hana.html) 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**: hdb
    - **dataSourceName**: _See [data source name](#sap-hana-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: "hdb",
        dataSourceName: "hdb://username:password@myserver:30015",
        table: "SCHEMA.TABLE",
    )
```

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

```
hdb://<user>:<password>@<host>:<port>?<connection-property>=<value>&<connection-property>=<value>&...
hdb://<user>:<password>@<host>:<port>?DATABASENAME=<tenant-db-name>
hdb://?KEY=<keyname>
```

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

| Flux data type                                | SAP HANA data type                              |
| :-------------------------------------------- | :---------------------------------------------- |
| [float](/flux/v0/data-types/basic/float/)   | DOUBLE                                          |
| [int](/flux/v0/data-types/basic/int/)       | BIGINT                                          |
| [string](/flux/v0/data-types/basic/string/) | NVARCHAR(5000)                                  |
| [bool](/flux/v0/data-types/basic/bool/)     | BOOLEAN                                         |
| [time](/flux/v0/data-types/basic/time/)     | {{< req text="\*" color="magenta" >}} TIMESTAMP |

{{< req text="\*" color="magenta" >}} The SAP HANA **TIMESTAMP** data type does
not store time zone information and
[SAP strongly discourages storing data in the local time zone](https://blogs.sap.com/2018/03/28/trouble-with-time/).
