To query [SAP HANA](https://www.sap.com/products/hana.html) 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**: hdb
    - **dataSourceName**: _See [data source name](#sap-hana-data-source-name)_
    - **query**: SQL query to execute

```js
import "sql"

sql.from(
    driverName: "hdb",
    dataSourceName: "hdb://username:password@myserver:30015",
    query: "SELECT * FROM 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>
```

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

| SAP HANA data type                              | Flux data type                              |
| :---------------------------------------------- | :------------------------------------------ |
| TINYINT, SMALLINT, INTEGER, BIGINT              | [int](/flux/v0.x/data-types/basic/int/)     |
| REAL, DOUBLE, DECIMAL                           | [float](/flux/v0.x/data-types/basic/float/) |
| {{< req text="\*" color="magenta" >}} TIMESTAMP | [time](/flux/v0.x/data-types/basic/time/)   |

{{% caption %}}
All other SAP HANA data types are converted to strings.  
{{% /caption %}}

{{< 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/).
