Simplify SQL Queries with the DECLARE Command

Summary

The DECLARE command in SQL can simplify queries with varying parameters. Instead of repeatedly using a WHERE statement for different time periods, you can declare variables before your query and adjust them for the desired timeframe. For instance, you can assign names to your variables along with their respective data types, such as '@start_date' and '@end_date' storing 'date' data type.
