How can we list all the columns of a MySQL view as we can list the columns of a MySQL table?

MySQLMySQLi Database

As we know that views are a type of virtual tables and are the composition of tables too hence we can use the same query to list all the columns of a MySQL view as we can list the columns of a MySQL table. In other words, we can use SHOW FULL COLUMNS statement to get the structure of a MySQL view. Its syntax would be as follows −

Syntax

SHOW FULL COLUMNS FROM View_name;

Here view_name is the name of the view from which we want to get the list of columns.

Example

Suppose if we want to get a list of columns of a view named ‘Info’ then it can be done with the help, of the following query −

mysql> SHOW FULL COLUMNS FROM INFO\G
*************************** 1. row ***************************
     Field: ID
      Type: int(11)
 Collation: NULL
      Null: YES
       Key:
   Default: NULL
     Extra:
Privileges: select,insert,update,references
   Comment:
*************************** 2. row ***************************
     Field: NAME
      Type: varchar(20)
 Collation: latin1_swedish_ci

       Key:
