What is the default storage engine used?

What is the default engine used in HeidiSQL
I am creating tables and so on but keep InnoDB instead of MyISAM.
How to check and or change to MyISAM option?

Cheers

You can specify the engine when you create a table using the pulldown menu on the top right of the dialog.

Afterwards you can change a tables engine easily by
- going to "Database" tab
- rightclick the table you want to change
- chose "Change type"
- click on the desired engine

If you do not specify the engine at creation time, the used engine depends on what's the default on the server. Run this query via the Query-tab to find out what's the default:

SHOW VARIABLES LIKE "storage_engine"

Most servers still have MyISAM as default. But I think you can change that default value on the server, adding a line to the my.cnf :

storage_engine=INNODB
