Using SAP HANA Connector

Data Bind using Data Query

Read/Display Data Query for SAP HANA:

Begin by crafting a SQL query to extract data from your SAP HANA database. For instance, consider the following query that retrieves data from the auth_permission table:

Query used:

SELECT * FROM auth_permission;

Query explanation:

This SQL query targets the auth_permission table within the SAP HANA database. By utilizing SELECT *, you're retrieving all available data. This forms the foundation for displaying valuable information.

Get Data Query

Integrate the fetched data into your application's interface.

a. Access the Controls section and introduce the Table grid control.

b. Navigate to Data Bind Options -> Quick Select -> Connector Library..

c. Opt for the SAP HANA connector and choose the query that aligns with your data presentation goals.
