```js import "sql" sql.from( driverName: "hdb", dataSourceName: "hdb://username:password@myserver:30015", query: "SELECT * FROM SCHEMA.TABLE", ) ```

To query SAP HANA with Flux:

  1. Import the sql package.

  2. Use sql.from() and provide the following parameters:

    • driverName: hdb
    • dataSourceName: See data source name
    • query: SQL query to execute
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
REAL, DOUBLE, DECIMAL float
{{< req text="*" color="magenta" >}} TIMESTAMP 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. For more information, see Timestamps in SAP HANA.
