How to find MySQL temporary table storage engine

Question

Hi I am working with Temporary table and I would like to know the temporary table storage Engine (InnoDB, MyISAM .... )

I am using the following code to find out bu

Answer 1

You will want to search the temporary tables store information_schema.temporary_tables or the global temporary table store information_schema.global_temporary_tables.

Try

`SELECT ENGINE FROM information_schema.temporary_tables WHERE TABLE_SCHEMA='test' AND `TABLE_NAME`='temporary_table'`

Answer 2

Unfortunately:

Currently, the [INFORMATION_SCHEMA.]TABLES table does not list TEMPORARY tables.

I would advise parsing the result of SHOW CREATE TABLE temporary_table;

To extract only the ENGINE of this return value:

$rset = mysql_query('SHOW CREATE TABLE temporary_table;')
$row = mysql_fetch_array($rset, MYSQL_BOTH);
preg_match('/ENGINE\=(?P<engine>\w+)/', $row[1], $matches);
echo $matches['engine'];
