How do I update all MySQL table rows at the same time?
For example, I have the table:
id | ip | port | online_status |
1 | ip1 | port1 | |
2 | ip2 | port2 | |
3 | ip3 | port3 | |
4 | ip4 | port4 | |
5 | ip5 | port5 | |
I'm planning to create cronjob and monitor some servers, but I don't know exactly how to update them all from the table at the same time. What are some examples on how to do that?
