In the output above, what does the % (percentage sign) mean ?
mysql> show processlist;
+------+--------+----------------------+----------+---------+------+--------------+------------------------------------------------------------------------------------------------------+
| Id | User | Host | db | Command | Time | State | Info |
+------+--------+----------------------+----------+---------+------+--------------+------------------------------------------------------------------------------------------------------+ |
| 1112 | usr | %:51506 | db | Query | 0 | Sending data | CALL `db`.`GetAllHistory`('.............', '...................') |
| 1127 | usr | %:56805 | db | Query | 1 | Sending data | SELECT ........
Other than being a wildcard in some contexts, I could not find it in the online documentation or other places.
