  Hi!

  I have one column with datetime data.

  example:

  01-06-2010 00:03:00

  I need to convert that into two columns:

  date

  01-06-2010

  and

  time

  00:03:00

  thanks in advance.

  A lot of times this sort of thing is better done on the interface side.

  However, if you need to do this via T-SQL, I would suggest you read this article[/url] by Seth Phelabaum.

  select

  a.DT,

  Date_Only = dateadd(dd,datediff(dd,0,a.DT),0),

  Time_Only = a.DT-dateadd(dd,datediff(dd,0,a.DT),0)

  from

  ( -- Test Data

  select DT = convert(datetime,'1753-01-01 00:00:00.003')

  union all

  select DT = convert(datetime,'1753-01-01 07:21:09.997')

  union all

  select DT = convert(datetime,'1753-01-01 23:59:59.997')
