SELECT pl.id,pl.user,pl.state
,it.trx_id,it.trx_mysql_thread_id,it.trx_query AS blocked_query
,it2.trx_id AS blocking_trx_id,it2.trx_mysql_thread_id AS blocking_thread,it2.trx_query AS blocking_query
FROM information_schema.processlist AS pl
INNER JOIN information_schema.innodb_trx AS it ON pl.id = it.trx_mysql_thread_id
INNER JOIN information_schema.innodb_trx AS it2 ON pl.id = it2.trx_mysql_thread_id
INNER JOIN information_schema.innodb_lock_waits AS ilw ON it.trx_id=ilw.requesting_trx_id AND it2.trx_id = ilw.blocking_trx_id;

WE NEED TO USE information_schema.innodb_trx TABLE TWICE TO JOIN ON ilw.requesting_trx_id AND ilw.blocking_trx_id TO GET BLOCKED AND BLOCKING TRANSACTION DETAILS SEPERATELY
