As we know that views are a type of virtual tables and are a composition of tables too hence we can use the same query to get the structure of a view which we use to get the structure of a table. In other words, we can use DESCRIBE statement to get the structure of a MySQL view. Its syntax would be as follows −SyntaxDESCRIBE view_name;Here, view_name is the name of the view of which we want to get the structure.ExampleSuppose we want to get the structure of a view named ‘Info’ then it can be done with the help, of the following query ...

With the help of DROP VIEW statement, we can drop a MySQL view from the database. Its syntax would be as follows −SyntaxDROP VIEW [IF EXISTS] view_name;Here view_name is the name of the view which we want to delete from the database.ExampleSuppose if we want to drop a view named info_less then the following query will delete if −mysql> DROP VIEW IF EXISTS Info_less; Query OK, 0 rows affected (0.03 sec)

The INFORMATION_SCHEMA database has a VIEWS table that contains view metadata i.e. data about views. To illustrate it we are taking the example of a view named ‘Info’.ExampleThe following query will show the metadata of a view named ‘Info’ −mysql> SELECT * from INFORMATION_SCHEMA.VIEWS WHERE TABLE_NAME = 'Info' AND TABLE_SCHEMA = 'query'\G *************************** 1. row *************************** TABLE_CATALOG: def  TABLE_SCHEMA: query    TABLE_NAME: info VIEW_DEFINITION:select`query`.`student_info`.`id`AS`ID`, `query`.`student_info`.`Name` AS `NAME`, `query`.`student_info`.`Subject` AS `SUBJECT`, `query`.` student_info`.`Address` AS `ADDRESS` from `query`.`student_info`         CHECK_OPTION: NONE         IS_UPDATABLE: YES              DEFINER: root@localhost       ...
