I'm looking to translate an SQL query into linq

INNER JOIN Usrs ON
SAQ.UserId =

Forms Data Controls :: Linq Query To Fill Datagrid?

Mar 14, 2010

'm not sure if this is the right forum, but I couldnt find one for linq related questions.I have the following problem. I have four tables, One with users, one with projects, one with the users and the projects they are in (joinProjectTable) and on table where the users can fill in there worked hours for a certain project. These hours are filled in on a daily base. Now every month there is going to be created a report on the workedHours table so there is visible which user has entered how many hours for a certain project. On this report there is gonna be a billing for the company where for the hours are worked. This is the easy part, the hard part is the following.

companies also want to have a list of users that didn't entered any hours for that particular month for a particular project. So I have to write a linq query that would look in the joinprojecttable to see which users are joined to which projects, and than with that join it should look if that particular combination (user+project) is in anyway entered in the workedhourstable for that particular month. If not this has to be shown in the datagrid, for every user that isnt in the workedhourstable for that month. So it should be a certain NOT query, but I can't seem to figure it out.does anyone have any idea to accomplisch this in Linq2Sql? I'm using VB instead of C#.

Forms Data Controls :: Selecting Radio Buttons In A Gridview With Dataset From Linq Query?

Oct 13, 2010

I've got a gridview that will allow clients to edit options they've already entered on another page. The gridview has three radio buttons in it each with a value of 1,2,3. The option value in the dataset is 1,2 or 3 respectively. I would like to have the radiobutton with the corresponding value selected in the gridview so they can see what they previously chose and will then be able to edit, if they wish.

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?

Linq Query - How To Select Inner Query Into List

Oct 17, 2010

I am writing a linq query to select a blogpost,

[code]....

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.

and then i created a UI with a controller

LINQ-to-SQL Retrieving Data From A Different Query!

Jun 28, 2010

I have a web application that uses LINQ-to-SQL. It has a very strange issue, where a LINQ command retrieves the data that is supposed to be returned by another, totally different query that runs in a different thread. What could be the cause of this?

Specifically, a user accesses the application from his machine, opening a certain page. At the same time, another user accesses a different page from his (different) machine. One of the queries throws an exception, while the other returns the data of the first one, which comes from a very different table!

The case is always reproducible, whenever we stress the application with these two users. I've checked but I don't see any shared variables of any kind. What else could the problem be? What should I be looking for?

ADO.NET :: LINQ Entity Framework Query - Construct "nested" Query?

Jan 22, 2011

I have a web app for our golf club. When I compute handicap index for each golfer, I have to select the most recent scores and then a subset of those scores depending on how many rounds of golf the golfer has played. All the scores are entered into a single SQL Express table called "Rounds". Verbally, this is what I'm trying to do:

1) select the twenty most recent golf scores (sort on date descending, "take(20)") [if less than 20 records, then select all available];

2) for this set of records, select the 10 lowest scores (or smaller number if golfer has less than 20 rounds);

3) compute the average round differential for the subset of records, etc. to calculate handicap index (this step is working ok...)

My current VB code has this LINQ query (which is flawed -- it selects the lowest handicap differential scores of ALL records for the filtered user):

[Code]....

How do I modify this query to accomplish items 1) & 2) above? It seems this should be simple, but my experience with queries is still limited.

WCF / ASMX :: Linq Query Returns No Data?

Jul 23, 2010

I am trying to figure out why this service does not return any data. The service does not error out is just doesn't return any data. When I take the Linq into LinqPad the query returns exactly as I expect. So I am wondering if the problem is getting my return data into a List<string>??

[Code]....

I don't know what else to say to help. When I set a break point on the "return LoanStats" line a quick watch shows an empty results view.
