MySQL视图：将Unix时间戳转换为日期时间

Question

How do I convert timestamps in a MySQL View?

I have a MySQL View for data exchange between 2 different software tools. The original table is a unix timestamp as int(11) . The other software expects a DATETIME.

I have a VIEW like this:

CREATE VIEW `myView` AS 
select 
date_format(from_unixtime(`myUnixTimestamp`),_utf8'%d/%m/%Y %H:%i:%s') 
AS `Date-Entered`
from ...

This VIEW statement creates a varchar(24) - which is better than nothing as it can be converted - but the conversion makes some problems.

Is there any way to create a DATETIME field instead of a VARCHAR with the view?

Answer 1

You can cast the value to datetime :

-- print a UNIX timestamp (as returned by NOW()) as DATETIME
SELECT CAST( DATE_FORMAT( NOW( ) , '%Y-%m-%d' ) AS DATETIME );

Answer 2

Thanks for the answers, I tried some combinations, and this one worked (so easy, its a shame...):

CREATE VIEW `myView` AS 
select 
from_unixtime(`myUnixTimestamp`)
AS `Date-Entered`
from ...

View Structure shows: Date-Entered, type: datetime

Answer 3

try

CREATE VIEW `myView` AS 
select 
FROM_UNIXTIME([unix timestamp],'%d/%m/%Y %H:%i:%s') 
AS `Date-Entered`
from ...
