How can I get the list of columns from a table in the other database than weare currently using IN operator?

It can be done with the SHOW COLUMNS statement. Its Syntax would be as follows:

Syntax

SHOW COLUMNS FROM tab_name IN db_name

Here, 

  • tab_name is the name of the table from which we want to see the list of columns.
  • Db_name is the name of the database, in which the table is stored

Example

In the example, we are currently using the database ‘query’ and getting the list of columns
from a table named ‘arena’ stored in MySQL ‘database’:

mysql> SHOW COLUMNS FROM arena IN mysql\G

  Field: id
   Type: int(10) unsigned zerofill
   Null: NO

*************************** 2. row ***************************
  Field: Photo
   Type: blob
