# Ending a session or query for RDS for MySQL
Ending a session or query

You can end user sessions or queries on DB instances by using the `rds_kill` and `rds_kill_query` commands. First connect to your MySQL DB instance, then issue the appropriate command as shown following. For more information, see [Connecting to your MySQL DB instance](USER_ConnectToInstance.md). 

```
CALL mysql.rds_kill(thread-ID)
CALL mysql.rds_kill_query(thread-ID)
```

For example, to end the session that is running on thread 99, you would type the following: 

```
CALL mysql.rds_kill(99); 
```

To end the query that is running on thread 99, you would type the following: 

```
CALL mysql.rds_kill_query(99); 
```
