How can I get the list of columns from a table in the database we are currently using?

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

Syntax

SHOW COLUMNS FROM tab_name

Here tab_name is the name of the table from which we want to see the list of columns.

Example

In the example we are getting the list of columns from a table named Student_info −

mysql> SHOW COLUMNS FROM Student_info\G
*************************** 1. row ***************************
  Field: studentid
   Type: int(11)
   Null: YES
    Key:
Default: NULL
  Extra:
*************************** 2. row ***************************
  Field: Name
   Type: varchar(40)
   Null: YES
    Key:
Default: NULL
  Extra:
*************************** 3. row ***************************
  Field: Address
   Type: varchar(20)
   Null: YES
    Key:
Default: NULL
  Extra:
*************************** 4. row ***************************
  Field: Subject
   Type: varchar(20)
   Null: YES
