SQL SELECT Statement

The SQL SELECT statement is used to query data from a database. The data returned is stored in a result table, sometimes called the result set.

Here is the basic syntax of the SELECT statement:

SELECT column1, column2, ...
FROM table_name;

Key Components:

1. SELECT Clause: Specifies the columns to be retrieved. You can list specific columns or use * to select all columns.
2. FROM Clause: Specifies the table from which to retrieve the data.

Example:

Suppose you have a table named Employees with the following columns: EmployeeID, FirstName, LastName, Department, and Salary.

1. Selecting Specific Columns:

SELECT FirstName, LastName, Department
FROM Employees;

This statement retrieves the FirstName, LastName, and Department columns from the Employees table.

2. Selecting All Columns:

SELECT *
FROM Employees;

This statement retrieves all columns from the Employees table.
