How to utilize Oracle in a select query?

edit

To utilize Oracle in a select query, follow these steps:

1. Connect to the Oracle database using your preferred tool or interface
2. Create a query using the SELECT statement, specifying the columns you want to retrieve from the database, and the table or tables you want to retrieve data from. For example, if you want to retrieve all columns from a table called 'customers', you would use the following syntax:

SELECT * FROM customers;

1. You can also filter the results by specifying a condition using the WHERE clause. For example, if you want to retrieve only the customers with a specific last name, you can use the following query:

SELECT * FROM customers WHERE last_name='Smith';

1. You can also use aggregate functions such as COUNT, AVG, SUM, or MAX to perform calculations on the data. For example, you can use the following query to retrieve the number of customers in a table:

SELECT COUNT(*) FROM customers;

1. Finally, you can use the ORDER BY clause to sort the results by one or more columns. For example, to retrieve all customers sorted by their last name in ascending order, you can use the following query:

SELECT * FROM customers ORDER BY last_name ASC;

These are just some of the ways you can utilize Oracle in a select query. The syntax may vary depending on the specific tool or interface you are using, but the basic principles remain the same.
