Synopsis

SHOW [STORAGE] ENGINES

This statement lists the table types or storage engines available for the version of MySQL running on the server. It states which are disabled on the server and which are enabled, as well as which is the default type. It also provides comments on each type. The STORAGE keyword is optional and has no effect on the results. This SQL statement replaces SHOW TABLE TYPES, which produced the same results, but is deprecated. Here is an example of this statement:
