Select and load data from an Apache Hive database

Once you have created a connection to an Apache Hive database, you can select data and load it into a Qlik Sense app or a QlikView document. In Qlik Sense, you load data through the Add data dialog or the Data load editor. In QlikView, you load data through the Edit Script dialog.

The SELECT statement does not include a WHERE clause, but one can be added in the Data load editor after the script built automatically in the script panel is inserted there. The SELECT statement for the Apache Hive Connector supports the addition of WHERE clause.
