Requirement: There are 2 tables Sales and Revenue with columns Date, Product, Sales and Date Product, Revenue. Union data from these 2 tables and display Sales / Revenue value.
Create 2 query objects with the data items Date, Product, Sales and Revenue with Sales set to 0 in query 1 and Revenue set to 0 in query 2. You may run into numeric overflow errors with Teradata cause in Query 1 Sales is set to 0. So Teradata considers data type of Sales to be integer rather than decimal thus causing the error. Cast the 0's to appropriate data types and the issue gets resolved.
