Syntax
The general syntax of the statement is as follows:
mysql> SHOW ENGINES;
This command displays the output in a tabular format.
or
mysql> SHOW ENGINES \G
The statement displays the storage engines that are compiled into the MySQL server and whether
they are available at runtime.
Examples
The command with \G terminator displays the output in the row format.

The Support column can have values like:
- YES
- NO
- DISABLED
- DEFAULT
The value in the Support column is YES or NO, to indicate that the storage engine is or is not available.
DISABLED if the engine is present but turned off, or DEFAULT for the storage engine that the server
uses by default. The InnoDB storage engine is the default engine in the above example.
