SQL Server 2008的Select语句中的In子句

Question

I have an SQL Server Query:

select *from table1 where column in ('list of values')

When I execute this, I get all the details, however, when I do this:

select *from table1 where column in ('list of values') and date_of_req='2011-03-15'

I get an empty table. All the column headings are there, but with no data. How to overcome this? I basically want to match all of those values in the IN clause and the date and display only that data.

Where am I going wrong?

Answer 1

DATETIME likely has a time part too. Also, get in the habit of using the language insensitive datetime literal form ( 'YYYYMMDD' ) Try:

select *from table1 where column in ('list of values') 
and date_of_req=>'20110315'
and date_of_req < '20110316';

Answer 2

You probably have a time part as well. Ensure you are getting the date part out of date_of_req.

Answer 3

date_of_req have time part as well. So you can compare your date part of your column with below query

select * 
from table1 
where column in ('list of values') 
  and CONVERT(VARCHAR(10), date_of_req, 111) = '2011-03-15'
