Notes:
The
PROCESSLISTtable is a nonstandard table. It was added in MySQL 5.1.7.Like the output from the corresponding
SHOWstatement, thePROCESSLISTtable will only show information about your own threads, unless you have thePROCESSprivilege, in which case you will see information about other threads, too. As an anonymous user, you cannot see any rows at all.If an SQL statement refers to
INFORMATION_SCHEMA.PROCESSLIST, then MySQL will populate the entire table once, when statement execution begins, so there is read consistency during the statement. There is no read consistency for a multi-statement transaction, though.
The following statements are equivalent:
SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST SHOW FULL PROCESSLIST
