C# - Mvc LINQ Datetime - Accommodate NewsFillter In The Postsidebar Query In The Pstmt Object?

Nov 23, 2010

string NewsFillter = string.Empty;
List<string> PublishDatePostMeta = (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=="Publish Date"
select pstmt.vcr_MetaValue).ToList();
int DatesCount = PublishDatePostMeta.Count();
foreach (string PublishDate in PublishDatePostMeta)
{
if (PublishDate != "")
{
NewsFillter += System.DateTime.Now + ">=" + Convert.ToDateTime(PublishDate);
}
}
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;

The thing is that how NewsFillter would be accomdated in the postsidebar query in the pstmt object after true ( i would be putting it in contains,equals join or what). is there any way that a chunk (between &&s) return enumerable and i can get away with this. at this moment it is not allowing that

Insert And Query A DateTime Object In SQLite DB From C#?

Mar 17, 2010

Consider this snippet of code:

string sDate = string.Format("{0:u}", this.Date);
Conn.Open();
Command.CommandText = "INSERT INTO TRADES VALUES(" + """ + this.Date + """ + "," +this.ATR + "," + """ + this.BIAS + """ + ")";
Command.ExecuteNonQuery();

Note the "this.Date" part of the command. Now Date is an abject of type DateTime of C# environment, the DB doesnt store it(somewhere in SQLite forum, it was written that ADO.NET wrapper automatically converts DateTime type to ISO1806 format)

But instead of this.Date when I use sDate (shown in the first line) then it stores properly.

My probem actually doesnt end here. Even if I use "sDate", I have to retrieve it through a query. And that is creating the problem

Any query of this format

SELECT * FROM <Table_Name> WHERE DATES = "YYYY-MM-DD"

returns nothing, whereas replacing '=' with '>' or '<' returns right results.

So my point is:

How do I query for Date variables from SQLite Database.

And if there is a problem with the way I stored it (i.e non 1806 compliant), then how do I make it compliant

Web Forms :: Globalized Datetime Object As Sql Query Parameters?

Dec 28, 2010

I have an application which uses globalization, hence the datetime objects are globalized based on current culture. These datetime objects are passed as sql parameters for a select query. The database stores the datetime in only one format (en-US style). Although the query is parameterized the final query generated does not contain converted values (format that Database is expecting).

C# - Set A Value On A Linq Object During The Query?

Feb 16, 2010

I have a simple query i.e.

var trips = from t in ctx.Trips
select t;

The problem is that I have an extra property on the Trip object that needs to be assigned, preferably without iterating through the returned IQueryable.

Does anyone know how to set the value during the query? (i.e. select t, t.property = "value")

Rewriting This Linq Query To Move It From Code-behind To DAL As Reusable Object?

Apr 4, 2011

I'm working to move my simple asp.net website to a three layer architecture. Currently I have Linq queries like the one below in my code-behind files. Basically this code snippet retrieves a collection of customer data from the database and then binds it to a grid control.

I'm wondering if someone can guide me on how to rewrite this in order to move it to my newly-created data access layer. I'm thinking I will turn it into a class (e.g. GetUserBoxesByStatus()) that can be reused throughout the site.

var boxes = from p in sbm.Packages
where p.UserID == CurrentUserId && p.StatusID > 1 && p.StatusID < 3
select new { p.PackageTag, p.PackageName, p.DateReceived, p.DateShipped }; [code]....

Some of the options that I've investigated but have not had success implementing are the following:

DataTable --- returning a DataTable seems like the best solution but it also appears to require a lot of potentially unecessarry code to define a table (isn't the data source already mapped in my Linq 2 Entities dbml?)

IEneuerable --- I think I could pass an IEnumerable list between the layers but after reading many tutorials about Linq I'm still a little lost DTO --- Conceptually I think I understand what a DTO is but I am not clear on how to begin implementing this approach POCO --- Again, the concept seems logical enough but I don't know how to put this into practice

how they would tackle this using one of the above or some other solution.

Linq Query Returning Less Records Than Sql Query?

Mar 19, 2011

I am facing a big problem with simple linq query.. I am using EF 4.0..

I am trying to take all the records from a table using a linq query:

var result = context.tablename.select(x=>x);

This results in less rows than the normal sql query which is select * from tablename;

This table has more than 5 tables as child objects (foreign key relations: one to one and one to many etc)..

This result variable after executing that linq statement returns records with all child object values without doing a include statement.. I don't know is it a default behavior of EF 4.0 . I tried this statement in linqpad also..but there is no use... But interesting thing is if I do a join on the same table with another one table is working same is sql inner join and count is same..but I don't know why is it acting differently with that table only.. Is it doing inner joins with all child tables before returning the all records of that parent table?

So the BlogPostTags table only contains 2 fields, BlogPostID and TagID.

When i run the query above i get 3 results back. Same blogpost 3 times but with 1 tag in each. It should return 1 post with 3 tags. The problem lies in the Tags query above.

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)

DataSource Controls :: Linq OrderBy With Nullable DateTime?

May 3, 2010

Is there a way to use the OrderBy command in Linq with a DateTime field using the Date portion only (without the Time Stamp portion) that is nullable such as in the following query?

var query1 = from myTable in MyTable
where myTable.EnteredDate != null
group myTable by myTable.EnteredDate into myOutput[code]....

Since myTable.EnteredDate is a DateTime field that can contain nulls, it does not support the .Date conversion call such as
myTable.EnteredDate.Date

Is there a way to convert the myTable.EnteredDate field into a date only string in the group by portion?

How To Store DateTime Object With CultureInfo

Mar 2, 2011

Does the DateTime object stores the CultureInfo with it, or you need to use the Formatter to format the DateTime according to current culture ?

I have a class property that retuns a DateTime. Within that property I am setting the DateTime object with current culture information using CultureInfo object. Below is the code for class property I am using:

public DateTime PrintedQuoteDate {
get{
DateTime printQuoteDate = DateTime.Today;
// cInfo = CultureInfo object
return Convert.ToDateTime(printQuoteDate , cInfo);
}
}

So my question is when I will use the above property in my code, will it have the corrosponding culture information that I am setting in its get method, or I will have to use the same CONVERT code for formatting date time. The restriction here is that the Property should return only DateTime type.
