What is the difference between ‘set’ and ‘select’ in the database?

In the database, set and select are two distinct operations.

1. Set operation: The set operation is used to modify data in the database, allowing for updating, inserting, or deleting data. The set statement can be used to set the value of a specified field to a specific number or string. For example, the set statement can be used to set the value of a field to a specific number or to modify the value of a field to be double that of another field.
2. The Select operation is used to query data from a database, allowing users to retrieve records from a data table that meet specific conditions. By using the Select statement, users can choose specific rows and columns of data from the database and return the results of the query. For instance, the Select statement can be used to find information on all employees in a database, or to find information on orders with sales amounts greater than 1000.

In general, the set operation is used to modify data, while the select operation is used to retrieve data. Both are fundamental operations commonly used in database operations.
