CREATE OR REPLACE view_name AS SELECT- statement Code language: SQL (Structured Query Language) ( sql ) To modify a view, either adding new columns to the view or removing columns from a view, you use the same CREATE OR REPLACE VIEW statement. Job LIKE 'A%' GROUP BY job Code language: SQL (Structured Query Language) ( sql ) Modifying SQL views Of course, you can apply filtering or grouping as follows: SELECT SELECTĮmployee_contacts Code language: SQL (Structured Query Language) ( sql ) The following statement selects data from the employee_contacts view. Querying data from views is the same as querying data from tables. ORDER BY first_name Code language: SQL (Structured Query Language) ( sql ) Querying data from views

CREATE VIEW payroll (first_name, last_name, job, compensation) AS SELECT ORDER BY first_name Code language: SQL (Structured Query Language) ( sql )īy default, the names of columns of the view are the same as column specified in the SELECT statement. If you want to rename the columns in the view, you include the new column names after the CREATE VIEW clause as follows: CREATE VIEW view_name(new_column_list)ĪS SELECT- statement Code language: SQL (Structured Query Language) ( sql )įor example, the following statement creates a view whose column names are not the same as the column names of the base tables. CREATE VIEW employee_contacts AS SELECTįirst_name, last_name, email, phone_number, department_nameĭepartments d ON d.department_id = e.department_id Second, construct a SELECT statement to query data from multiple tables.įor example, the following statement creates the employee contacts view based on the data of the employees and departments tables. To create a view, you use the CREATE VIEW statement as follows: CREATE VIEW view_nameĪS SELECT- statement Code language: SQL (Structured Query Language) ( sql )įirst, specify the name of the view after the CREATE VIEW clause. Rather than give the users access to database tables, you create a view to revealing only necessary data and grant the users to access to the view. For example, you can create a view of salary data for the employees for Finance department. Views help you pack the data for a specific group of users. For example, instead of issuing a complex SQL query each time you want to see the data, you just need to issue a simple query as follows: SELECT column_listįROM view_name Code language: SQL (Structured Query Language) ( sql ) Views allow you to store complex queries in the database. That virtual table then is used as the source table of the query. Whenever you issue a SELECT statement that contains a view name, the RDBMS executes the view-defining query to create the virtual table. The relational database management system (RDBMS) stores a view as a named SELECT in the database catalog. A view is like a virtual table produced by executing a query. SQL provides you with another way to see the data is by using the views. When you want to see the data of these tables, you use the SELECT statement with JOIN or UNION clauses. Introduction to the SQL ViewsĪ relational database consists of multiple related tables e.g., employees, departments, jobs, etc.
