How to get primary key of table?

Question

Is there a way to get the name of primary key field from mysql-database? For example:

I have a table like this:

+----+------+
| id | name |
+----+---         


        

Answer 1

A better way is to use SHOW KEYS since you don't always have access to information_schema. The following works:

SHOW KEYS FROM table WHERE Key_name = 'PRIMARY'

Column_name will contain the name of the primary key.
