How to Convert MM/DD/YYYY to YYYY/MM/DD in SQL Reporting Services

Question

i am having difficulty of converting a parameter field, called @startdate, on sql reporting services report to YYYY/MM/DD format.  the parameter @Startdate was set to Data/Time.  @Startdate is 6/1/2014 12:00:00 and I want to convert it
to 2014/06/01.  I want to compare @Startdate with a column in database called Begindate which is in format of YYYY/MM/DD hh:mm:ss.  I tried the followings
select * from Atable where cast(Atable.Begindate as date) >= cast(@Startdate as date)
select * from Atable where cast(Atable.Begindate as date >= cast(convert(datetime, @Startdate) as date)
SQL Reporting Services only gives me Text, Boolean, Date/Time, Integer and Float.
Regards,

Hi Elmucho,
Sorry for the delay. I tested with the sample data you provided, however everything works well in-house. Could you please creste a new report and check the result. Here are the steps I performed:
1.  Create a table and insert the following data:
Name (varchar(50))    Begindate (datetime, not null)    
Lastdate (datetime, not null)
bob                          
2008-01-01 08:08:08.000      2010-10-10  
10:10:10.000
alice                         
2010-10-10 10:10:10.00       2011-11-11
  11:11:11.000
smith                       
2011-11-11 11:11:11.00       2012-12-12   
12:12:12.000    
2. Open SQL Server Data Tools, create the data source and add the dataset with the below query:
SELECT     Name, Begindate, Lastdate
FROM         [tablename ]
WHERE     (CAST(Begindate AS date) >= CAST(@Startdate AS date)) AND (CAST(Lastdate AS date) <= CAST(@Enddate AS date))
3. Then, click execute button, it prompts for inputting the parameter value.
@Startdate        
6/1/2008
@Enddate          
5/1/2014
Enter the date and press OK.
4. Here is the result in the query designer:
Insert a table and fields. Save the report and preview:
