WHAT ARE THE PREREQUISITES FOR SAP HANA SMART DATA ACCESS? Software Versions
You have installed SAP HANA SP7 and the remote data sources are available.
ODBC Drivers
You have installed the ODBC drivers for the databases you want to connect see SAP note 1868702 on each HANA node. If you installed ODBC drivers in your HANA exe directory as per note 1868702 these ODBC drivers will be removed during a revision update and have to be installed again after the update.
HOW TO CONNECT A REMOTE SOURCE AT A GLANCE?
In the HANA Studio under System Provisioning Remote Sources

For details on how to connect the databases for SAP HANA Smart Data Access as remote sources seethe SAP HANA Administration Guide System Administration and Maintenance Information SAP HANA Administration Guide (About SAP HANA Smart Data Access Adding Remote Data Sources).
Necessary Privileges:
For creating remote sources, the system privilege CREATE REMOTE SOURCE is required. For creating virtual tables, the object privilege CREATE VIRTUAL TABLE is required.
It is recommended to create the remote source with the HANA SAP<SID> user. If the remote source has not been created by the HANA SAP<SID> user, then the HANA SAP-<SID> user needs the object privilege CREATE VIRTUAL TABLE, granted by the owner of the remote source.
With this sql statement you can find the owner of the remote source:
select * from ownership where object_name = '<Name of the remote source>'

HOW TO VALIDATE THE REMOTE SOURCE CONFIGURATION?
In general there is a check option available inside the remote source configuration in the HANA Studio. Furthermore there is a tool available which can be accessed via the console for further details.
In the console in path /usr/sap/SID/home you can execute the following command example. This checks drivers and dependency files of a given data source type, in this case an SAP IQ database.
hdbsdautil -t iqodbc -S "
Driver=libdbodbc16_r.so;DatabaseName=SAPNLSDB;ServerName=SAPNLS_SERVER;CommLinks=tcpip( host=ld9455.wdf.sap.corp;port=2640)" -U TEST -P testtest –info

You can also query e.g. a table after having connected to the remote database with the following command. stsadm@ld9204:/usr/sap/STS/home> hdbsdautil -t iqodbc -S "
Driver=libdbodbc16_r.so;DatabaseName=SAPNLSDB;ServerName=SAPNLS_SERVER;CommLinks=tcpip( host=ld9455.wdf.sap.corp;port=2640)" -U TEST -P testtest -Q "select * from
SAPKIT_SDA.YSB_GEN_TABLE2" –nr
Example Output:
The general syntax is as follows:
Usage
hdbsdautil -t <data source type> -S <DSN or string> U <username> P <password>]] Q <SQL>] nr] [-info]
Arguments
-t Specify the type of data source, currently supported types: hanaodbc, aseodbc, iqodbc, tdodbc, odbc (generic adapter)
-S The connection information of the remote database, can be a DSN name in ODBC property file, or a custom string which contains all the connection information, e.g.:
-S "DSN=td13" or -S "dsn=td13"
-S "server=somehostname; port=5002;driver=libsybdrvodb-sqllen8.so"
If the data source type is "odbc", should add an "adapter_config_file=" section in the end of this area.
-U Specify the user name.
-P Specify the password. Can be omitted for interactive input.
-Q The SQL to be executed or queried after connected to the remoted database.
-nr "No Result", specify this if don't need to display the SQL query result.
