How do I see what a MySQL view is made of?
Following is the syntax −
show create view yourViewName;
Let us first create a table −
mysql> create table DemoTable -> ( -> StudentName varchar(20) -> ); Query OK, 0 rows affected (0.56 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Chris');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('Robert');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable values('David');
Query OK, 1 row affected (0.13 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
This will produce the following output −
+-------------+ | StudentName | +-------------+ | Chris | | Robert | | David | +-------------+ 3 rows in set (0.00 sec)
Following is the query to create view for a table −
mysql> CREATE VIEW view_DemoTable AS SELECT StudentName from DemoTable; Query OK, 0 rows affected (0.12 sec)
Following is the query to see what a MySQL view is made of −
mysql> show create view view_DemoTable;
Output
This will produce the following output −
+-------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+ | View | Create View | character_set_client | collation_connection | +-------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+ | view_DemoTable | CREATE ALGORITHM=UNDEFINED DEFINER=`root`@`%` SQL SECURITY DEFINER VIEW `view_DemoTable` AS select `DemoTable`.`StudentName` AS `StudentName` from `DemoTable` | utf8 | utf8_general_ci | +-------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+ 1 row in set (0.00 sec)
Let us check view records −
mysql> select *from view_DemoTable;
Output
This will produce the following output −
+-------------+ | StudentName | +-------------+ | Chris | | Robert | | David | +-------------+ 3 rows in set (0.05 sec)
