SHOW CREATE TABLE  lt tablename gt     Less parseable but more readable than SHOW TABLE STATUS

User · Answer

or just   show table status    just that this will llist all tables on your database

Yet another way  perhaps the shortest to get status of a single or matched set of tables   SHOW TABLE STATUS LIKE  table     You can then use LIKE operators for example   SHOW TABLE STATUS LIKE  field data

show table status from database name    It will list all tables from the mentioned database  Example output       show table status where name your desired table name    It will show the storage engine used by the mentioned table

To show a list of all the tables in a database and their engines  use this SQL query   SELECT TABLE NAME         ENGINE FROM   information schema TABLES WHERE  TABLE SCHEMA    dbname     Replace dbname with your database name

If you are a GUI guy and just want to find it in PhpMyAdmin  than pick the table of your choice and head over the Operations tab    Table options    Storage Engine  You can even change it from there using the drop-down options list   PS  This guide is based on version 4 8 of PhpMyAdmin  Can t guarantee the same path for very older versions
