Does MySQL support querying for the current running transaction id

PostgreSQL supports retrieving the current running transaction id using a query like this:

select txid_current();

Does MySQL have any such equivalent?

Starting with MySQL 5.7, you can see the current transactions in the performance schema.

See http://dev.mysql.com/doc/refman/5.7/en/events-transactions-current-table.html

Now, to find out the THREAD_ID of the current connection, use

SELECT THREAD_ID FROM performance_schema.threads
  WHERE PROCESSLIST_ID = CONNECTION_ID()

See http://dev.mysql.com/doc/refman/5.7/en/threads-table.html
