Hai,

Im new to sql server...
I want to convert a field in a table to DateTime.

The column(Column Name-DDateTime , Data type String) has data in this format 01-04-2008 15:12:52
i want to get records in a particular datetime range.Do not no how to proced.

usually i can write a query like this
select DDateTime from table_name where DDateTime between '01/27/2008 01:23:32' and '01/29/2008 01:23:32'

as the column's datatype is string im facing problem..

use CAST or CONVERT . You have to make sure the arguments that you're using for comparison have the same data type or can be explicitly converted.

Here's SELECT and the WHERE. Here's the BETWEEN and here are some samples.

use CAST on your field and the dates on the BETWEEN operator. Check your syntax.

Try this

SELECT * 
from vts3 
where convert(datetime,dubaidatetime, 105) between 
convert(datetime,'31-03-2008 01:00:00', 105) and 
convert(datetime,'02-04-2008 01:00:00', 105)

This puts your string dates into datetime format, so that they can be properly compared .... the 105 means the date is in dd-mm-yyyy format, check out Convert in BOL
