MySQL SHOW CREATE VIEW Statement
MySQL SHOW CREATE VIEW Statement
The SHOW CREATE VIEW statement shows a CREATE VIEW statement that creates the given view. MySQL statements designed to display the base table information can also display the view information. For example, the following statements also display the views:
- DESCRIBE
- SHOW TABLE STATUS
- SHOW TABLES
Syntax
The general syntax of the statement is as follows::
SHOW CREATE VIEW <view_name>
This statement displays the creation of a view from an existing table.
Example
The SHOW FULL TABLES lists the names of the tables and the views. The Table_type column displays the values that indicate the kind of object for each object. The column values are BASE TABLE, VIEW, or SYSTEM VIEW.
