• Key Concepts: 
  A query view is a virtual table in SAP HANA that is created by combining data from one or more tables. It is used to simplify complex queries and to provide a single point of access for data from multiple tables. Query views are stored in the database and can be used in applications, reports, and other queries. 
  
  How to use it: 
  Query views can be created using the SAP HANA Studio or the SQL console. To create a query view, you must first define the columns that will be included in the view. Then, you must define the source tables and the join conditions between them. Finally, you must define any filters or calculations that will be applied to the data. 
  
  Tips & Tricks: 
  When creating a query view, it is important to consider how it will be used. If the view will be used for reporting purposes, it is important to ensure that all of the necessary columns are included in the view. Additionally, if the view will be used for performance-critical operations, it is important to ensure that all of the necessary filters and calculations are applied to the data.
