Question

I am using the following code in Android to get current date time

Date currentDateTime = new Date();

And storing it in the sqlite table as

currentDateTime.ToString()

SO in the table the values are stored like so

"Tue Sep 11 20:32:39 IST 2012"
"Thu Sep 13 17:23:38 IST 2012"
"Thu Sep 13 17:34:38 IST 2012"
"Thu Sep 13 20:21:58 IST 2012"

Now I need to sort them in sqlite in desc order i.e.

select datetime(datecolumn) from table order by datetime(datecolumn) desc;

But when I do datetime(column) on the field it shows me null for all the rows on the date field

Obviously there is a data mismatch on the sqlite side. But I am not sure how to fix it – Is there a way I can still change the query on the sqlite side to be able to read this? Or do I have to change the JAVA code and insert the data in a sqlite readable format.

I need the times also since I am dealing with hourly data.

Answer 1

I would use

currentDateTime.getTime())

and store that value – less space needed in the database, and I assume much quicker to sort for sqlite
