Hello everyone, welcome to Educate Cube. Today, we will learn about aliases in SQL. An alias is a temporary name assigned to a table or column to make the query output more readable and to shorten the query syntax. Aliases help in identifying tables and columns with long or non-meaningful names.

For example, instead of using long names like 'sales_name' or 'product_ID,' you can use shorter aliases like 'A' or 'Product.' This makes queries easier to write and understand. Aliases are also useful when combining tables with different column names using UNION. By renaming columns with aliases, you can easily align them.

In summary, aliases improve the readability and manageability of SQL queries, making it easier to identify and work with tables and columns
