Question

I have a table called Raw_Data and the data looks like:

ID    Res_Date
1     2010-08-09 00:00:00.000
2     2010-07-09 00:00:00.000
3     2010-02-09 00:00:00.000

I am looking for output to be :

ID   Res_Date
1    2010-09-08 00:00:00.000
2    2010-09-07 00:00:00.000
3    2010-09-02 00:00:00.000

I tried following query;

Select ID,convert(datetime,Res_date,121) from Raw_data

but the format doesn’t change. Can anyone help me.

You can try this if you want dashes in your results

SELECT LEFT(convert(varchar, Res_date, 102), 4) + '-' 
    + LEFT(convert(varchar, Res_date, 105), 5) + ' '
    + RIGHT(convert(varchar, Res_date, 121), 12)
from Raw_data

If you want slashes:

SELECT LEFT(convert(varchar, Res_date, 102), 4) + '/' 
    + LEFT(convert(varchar, Res_date, 103), 5) + ' '
    + RIGHT(convert(varchar, Res_date, 121), 12)
from Raw_data

Here are some resources on formatting datetime
