14 Using Database Client Interfaces
SAP HANA provides client interfaces for connecting applications so they can retrieve and update data.
SAP HANA provides many methods for applications to access its data. For example, a spreadsheet application
could use ODBO to consume analytic views and enable users to create pivot tables, or a Web application could use
OData interfaces to access the data and display it.
SAP HANA can expose data with the following interfaces:
● Client interfaces, which are available as long as the SAP HANA clients are installed:
○ ODBC
○ ODBO
○ JDBC
● Web-based interfaces, which must be defined by the application developer, who determines what data to
expose and to whom:
○ OData
○ XMLA
○ Server-Side JavaScript

Defining Web-based Data Access [page 164]
SAP HANA extended application services (SAP HANA XS) provide applications and application developers
with access to the SAP HANA database using a consumption model that is exposed via HTTP.
14.1 Connecting via ODBC
SAP HANA provides an ODBC driver for connecting applications to the database.
Note: Make sure to use the 32-bit ODBC driver for 32-bit applications, and the 64-bit driver for 64-bit
applications.
1. Install the ODBC driver. The driver is installed as part of the SAP HANA client installation.
2. Write code to create a connection to the database. You can use one of the following methods:
○ Connection String (SQLDriverConnect): Use a connection string in the form:
DRIVER={};UID=;PWD=;
SERVERNODE=:;
should be one of the following:
○ HDBODBC: For 64-bit applications
○ HDBODBC32: For 32-bit applications
