timestamp types in sql

Recommended Posts

I was wondering if someone could explain timestamps to me... with the "current timestamp" etc

 

that's what i use currently, but i was wondering if i could use that for timestamp and then another kind to just log when the entry was first created, not when it was last updated. are there other types of timestamps that do other things in sql? thanks

You can have many TIMESTAMP columns within one table, but the first one can have two special properties

one is

ON UPDATE CURRENT TIMESTAMP

which automatically updates timestamp whenever row is upadted

 

second is

DEFAULT CURRENT TIMESTAMP

which inserts current timestamp when row is created

 

second and later TIMESTAMP columns can't have these properties and you can use them to store the time you wish
