DataSource Controls :: Linq Query To Select Parent Records Which Have Related Children

Jan 19, 2010

I have a basic CMS which I'm adding to a site to display some downloads organised into groups. I have two tables, one for the groups and one for the downloads. I'm using a repeated to display the groups with another repeater inside to display the children. This works perfectly.

However some of my download groups may not have any downloads related to them and I'd like to handle this by filter the groups so that only those with a relate download record(s) are shown.

I'm trying to do this with the query which populates the top repeater based on some ideas I read but I must be going wrong with the syntax.

Here is what I'm using to try and only select downloads groups which have downloads linked to them by the download group ID.


Can anyone offer any thoughts on how I should construct the query to perform this?

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 =>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?

Forms Data Controls :: Insert Master And Children Records With One-to-many Relationship From Formview

Jun 4, 2010

I've been wracking my brains for a while. I have a master record that I want to add children to. In a database it's a one to many relationship with a foreign key in the child table.

I have a formview that I want to use to fill in all the master record info, and choose the child info from a dropdownlist, and click an add button, and have the add button add the child info to some control on a page. Then when the user clicks insert, the formview has an ItemInserting EventHandler that will handle all the logic for inserting the master, grabbing its primary Key.

So, I know what to do, I'm just not sure of what control to use, or what memory object etc., that I want to store the child info in until the master record gets created.

I'm sure this has been done a million times, but for all my searching, I couldn't find anything to help me. Does anybody have some advice or can anybody point me to an internet resource where this has been hashed out?

Linq Query - How To Select Inner Query Into List

Oct 17, 2010

I am writing a linq query to select a blogpost,


The blogpost i am testing got 3 tags attached to it. The table structure is:

(table)BlogPost -> (table)BlogPostTags <- (table)Tags

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.

DataSource Controls :: Trying To Query Records From A Db Using A Date

Apr 14, 2010

I'm trying to query records from a db using a date. But somehow the db doesn't return records.

The datetime collums have the data stored in this format in the db as datetime :

12-Apr-10 12:45:12 AM
The string a have available is in this format : 12-Apr-10

I need to somehow strip the time part of so i can use my date string in the query.

When i use the below method the database converts the datetime to a rounded date (12-Apr-10 12:00:00 AM).
But when i query for that date i still get no results.

I tried this:

SELECT ID, PerformedBy, SystemId, ServerId, CAST(FLOOR(CAST(CreateDateTime AS FLOAT)) AS DATETIME) AS Expr1, Reason, Action, Summary, EnteredBy,
Collumn1, Collumn2
FROM Changes
WHERE ('Expr1 = '12-Apr-10 12:00:00 AM')

But this way the Expr1 collumn is not recognized.

I have to retreive all records from a table except 1 record. For example: I give example from default database in SQL ie "master" In "master" DB we have "spt_values" table. Now if I want to retreive all records from spt_values table except 1-1 record of type = A and type = B. To retreive all records its a simple query "Select * from spt_values where type in ('A','B')" -- this will returns 16 records.

C# - How To Read Parent And Children Data From SQL

Mar 14, 2011

I have two tables in SQL. The first defines the parent, and has a primary key column called ParentId. I also have a child table that has a primary key, and a foreign key as 'ParentId'. So the two tables form a one parent - to many children relationship.

The question is what is the most efficient way to pull the parent + child data C# code? The data has to be read into the following objects:


and use LINQ to merge all parents with children. This approach makes 2 trips to the db.

The third and final (also most inefficient) approach is to grab all parents, and while constructing each parent object, make a trip to the DB to grab all its children. This approach takes n+1 connections: 1 for all parents and n number of trips to get all children for each parent.

Any advise on how to do this easier? Granted i can't get away from using stored procedures, and I can't use LINQ2SQL or EF. Would you prefer Data Tables vs DataReaders and if so how to use either with approach 1 or 2?
