Creating MyISAM Table in Azure database for MySQL is enable?

Correct - MYISAM is not supported in Azure Database for MySQL, primarily due to the lack of transaction support which can potentially lead to data loss. This is one of the reasons MySQL switched over to InnoDB as the default.

As far as i know MYISAM is not supported in Azure database for MySQL. I'd suggest you switch to InnoDB instead.

In addition, I've also found a similar feedback in Azure feedback site.I'd suggest you keep track of that to see if anything changes.
