i included the table and its data as it would be impossible without that to understand. this is the meta scenario as you may notice that this was the query i wrote before when i was not checking the publish date
var postsidebar = from post in postrepository.GetAllPosts()
join pstmt in postrepository.GetAllPostMetas()
on post.int_PostId equals pstmt.int_PostId
where (post.int_PostTypeId == 4 && post.int_PostStatusId == 2 && post.int_OrganizationId == layoutrep.GetSidebarDetailById(SidebarDetailsId).int_OrganizationId)
&& (pstmt.vcr_MetaKey.Contains(filter) && pstmt.vcr_MetaValue.Contains("true"))
select post
how would i goint incoperate check for publish date in the query above( i want to bring all the records whose publish date is greater then todays date)

ADO.NET :: Duplicate Records Using Join In Linq To Entities?
Aug 5, 2010I am having trouble with duplicate records. I tested .distinct() in several areas and nothing helps.
I got the search criteria from the PreviousPage. I then used this criteria to search QueryA.
I did a search using QueryA. I took the results, and put the IDs into an array.
I then did a search using QueryB, that matched the IDs in the array. QueryB is used for the ListView and to page records.
Using test records. QueryA results = 2 records. The array.length = 2. QueryB results = 3. ?
What am I doing wrong ?
Some of my Code:
