What is the command used to define the view in SQL?

In the context of SQL, you can commonly use the CREATE VIEW to define a view. Here is how you can use it:-

CREATE VIEW view_name AS
SELECT column1, column2, …
FROM table_name
WHERE condition;
CREATE VIEW would help you in creating a new view.

VIEW NAME would help you replace this with the name that you want to give to your particular view.

SELECT COLUMN1, COLUMN 2, would specify the columns which you want to include in your particular view.

FROM TABLE_ NAME would specify the table from which you want to retrieve the data.

WHERE CONDITION: You can include WHERE Clause optionally to filter the rows that would be included in the view.

For example, to create a view that would select all the columns from a table named “employees” you would need to write:-

CREATE VIEW employee_view AS
SELECT * 
FROM employees;
 This would help you in creating a view named employee _ view which would contain all the columns from the table of employees.
Here is the java based approach given:-
Import java.sql.Connection;
Import java.sql.DriverManager;
Import java.sql.SQLException;
Import java.sql.Statement;
Import java.sql.ResultSet;
Public class DatabaseViewExample {
    // JDBC URL, username and password of MySQL server
    Private static final String URL = “jdbc:mysql://localhost:3306/your_database”;
    Private static final String USER = “your_username”;
    Private static final String PASSWORD = “your_password”;
    // JDBC variables for opening and managing connection
    Private static Connection connection;
    Private static Statement statement;
    Public static void main(String[] args) {
        Try {
            // Establishing a connection to the database
            Connection = DriverManager.getConnection(URL, USER, PASSWORD);
            Statement = connection.createStatement();
            // Creating a view
            String createViewSQL = “CREATE VIEW employee_view AS “ +
                                   “SELECT id, name, department, salary “ +
                                   “FROM employees “ +
                                   “WHERE department = ‘IT’”;
            Statement.executeUpdate(createViewSQL);
            System.out.println(“View created successfully.”);
            // Querying the view
            String queryViewSQL = “SELECT * FROM employee_view”;
            ResultSet resultSet = statement.executeQuery(queryViewSQL);
            // Processing the result set
            System.out.println(“ID | Name | Department | Salary”);
            While (resultSet.next()) {
                Int id = resultSet.getInt(“id”);
                String name = resultSet.getString(“name”);
                String department = resultSet.getString(“department”);
                Double salary = resultSet.getDouble(“salary”);
                System.out.println(id + “ | “ + name + “ | “ + department + “ | “ + salary);
            }
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            // Closing the resources
            Try {
                If (statement != null) {
                    Statement.close();
                }
                If (connection != null) {
                    Connection.close();
                }
            } catch (SQLException ex) {
                Ex.printStackTrace();
            }
        }
    }
