SELECT statement in SQL Server allows you to retrieve records from one or more tables in your SQL database.

The syntax for the SQL SELECT statement is:

SELECT columns * FROM tables WHERE predicates;

Select all fields from one table example:
How to use the SQL SELECT statement to select all fields from a table.

SELECT * FROM employees WHERE city = 'Delhi';

In this SQL SELECT statement, we've used * to signify that we wish to view all fields from the employees table where the employee resides in Delhi.

Selecting individual fields from one table example:
You can also use the SQL SELECT statement to select individual fields from the table, as opposed to all fields from the table. For example:

SELECT name, city, state FROM employees WHERE emp_id > 100;

This SQL SELECT statement would return only the name, city, and state fields from the employees table where the emp_id value is greater than 100.

Select fields from multiple tables example:
You can also use the SQL SELECT statement to retrieve fields from multiple tables.

SELECT orders.order_id, customers.name FROM customers  INNER JOIN orders ON customers.customer_id = orders.customer_id;

This SQL SELECT statement joins two tables together to gives us a result set that displays the order_id and customer name fields where the customer_id value existed in both the customers and orders table.
