# mysql.slow\_log Table
**System tables should not normally be edited directly. Use the related SQL statements instead.**
The `mysql.slow_log` table stores the contents of the [Slow Query Log](https://mariadb.com/docs/server/server-management/server-monitoring-logs/slow-query-log) if slow logging is active and the output is being written to table (see [Writing logs into tables](https://mariadb.com/docs/server/server-management/server-monitoring-logs/writing-logs-into-tables)).
It contains the following fields:
| Field | Type | Null | Key | Default | Description |

| user\_host | mediumtext | NO | | NULL | User and host combination. |
| query\_time | time(6) | NO | | NULL | Total time the query took to execute. |
| lock\_time | time(6) | NO | | NULL | Total time the query was locked. |
| rows\_sent | int(11) | NO | | NULL | Number of rows sent. |
| rows\_examined | int(11) | NO | | NULL | Number of rows examined. |
