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 |
| * TIMESTAMP | time |
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.
