19.22. The INFORMATION_SCHEMA PROCESSLIST Table

The PROCESSLIST table provides information about which threads are running.

INFORMATION_SCHEMA Name SHOW Name Remarks
ID Id MySQL extension
USER User MySQL extension
HOST Host MySQL extension
DB db MySQL extension
COMMAND Command MySQL extension
TIME Time MySQL extension
STATE State MySQL extension
INFO Info MySQL extension

For an extensive description of the table columns, see Section 12.5.5.31, “SHOW PROCESSLIST Syntax”.

Notes:

  • The PROCESSLIST table is a nonstandard table. It was added in MySQL 5.1.7.

  • Like the output from the corresponding SHOW statement, the PROCESSLIST table will only show information about your own threads, unless you have the PROCESS privilege, 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
