The intersect node is used to select the rows from one data source that also appear in another data source. You choose the columns on which the intersection check is made.

The minus node is used to select rows that appear in one data source but not another. Again, you choose the columns on which the minus check is made.

Watch this video to learn about the Set Operations - Intersect and Minus.

For the Minus node, the data sets are considered based on their order in the list of data sources for the node. Therefore, the output contains items from the FIRST data source that are NOT in the SECOND data source. In SAP HANA Cloud, it is possible to change the order of the data sources: just right-click on the Minus node and choose Switch Order.

Intersect and Minus operations are dynamic. A screen capture shows an example where country and name are mapped to the output of an Intersect node. If a query selects both columns, the combination of both columns determines the intersect result. If only name is selected, only name is compared and more rows may be returned than in the first query. For other details, refer to the following text.

Filtering relies on the list of attributes that are queried at runtime. In other words, a column that is provided by both source nodes, for example, Country, but is not queried at runtime, is ignored.
