R SAP Hana Integration with ODBC for Windows

I would like to connect to SAP Hana Database from RStudio. I've tested several libraries such as:

• RODBC

• RJDBC

And finally after some readings and research, I've determined that ODBC is the newer library instead of RODBC, and it has better performance compared to RJDBC.

I've started with the RStudio documentations:

1- SAP HANA Driver Installation link

2- RStudio introduction to ODBC package link

3- ODBC Package GitHub Page link

After following the driver installation for Windows 64-bit, I can see the driver HDBODBC from RStudio:

> library(odbc)
> sort(unique(odbcListDrivers()[[1]]))
[1] "Amazon Redshift (x64)"  "HDBODBC"  "ODBC Driver 17 for SQL Server"  "PostgreSQL ANSI(x64)"  "PostgreSQL Unicode(x64)"      
[6] "SQL Server"                   
> 

The below image is a capture when I was configuring the DSN where I provide the IP and Port:

Errors:

1- This is what I get when I attempt connecting to DSN:

> library(odbc)
> con <- dbConnect(odbc(), "HAN")
Error: nanodbc/nanodbc.cpp:983: HY000: [SAP AG][LIBODBCHDB DLL][HDBODBC] General error;1033 error while parsing protocol 
> 

2- This is what I get while I attempt to connect without DSN:

library(DBI)
con <- dbConnect(odbc::odbc(),
  driver = "HDBODBC",
  uid = "<user>",
  pwd = "<pass>",
  host = "<ip>",
  port = <port>)  

Error: nanodbc/nanodbc.cpp:983: HY000: [SAP AG][LIBODBCHDB DLL][HDBODBC] General error;-10719 Connect failed (invalid SERVERNODE '')

Miscellaneous troubleshooting information:

I've tested a connection and it is successful.

I used this with Tableau and it worked.

I've also used RJDBC and the java driver and it is working as well, but the performance is really bad:

jdbcDriver <- JDBC(driverClass="com.sap.db.jdbc.Driver",  
                   classPath="C:\\Program Files\\SAP\\hdbclient\\ngdbc.jar")

jdbcConnection <- dbConnect(jdbcDriver,
                            "jdbc:sap://<ip>:<port>/?autocommit=false",
                            "<username>",
                            key_get("<service>", keyring = "<keyring>"))

In your attempt without DSN the parameter ServerNode is missing; you used HOST instead, which is not the same parameter.

See the reference documentation here for details.
