Query SAP HANA

To query SAP HANA with Flux:

  1. Import the sql package.

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

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 typeFlux data type
TINYINT, SMALLINT, INTEGER, BIGINTint
REAL, DOUBLE, DECIMALfloat
* TIMESTAMPtime

All other SAP HANA data types are converted to strings.

* 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.

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
