Thread: Select date & time
Hello, I have a table in which I have three columns (for reasons I will not go into here): Date, time and time (milliseconds). However, I want to start using timestamps instead. Problem is, I don't know how to get the data in a proper format using selects. Say I have a table: > create table foo (ts timestamp) ..and I insert an entry: > insert into table foo (ts) VALUES (now()) This will yield an entry which looks something like: ts --------------------------- 2006-02-04 19:27:31.123456 I'm interested in retaining this information in the database, but not when I'm going to present it. I.e. I want to be able to create a query that will return: date | time | -----------+----------+---- 2006-02-04 | 19:27:31 | I figured out the date part: > select date(ts) from foo But how do I get the "time" part? Thankful for any tips. -- Kind Regards, Jan Danielsson Te audire non possum. Musa sapientum fixa est in aure.
