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?

DataSource Controls :: Select Query For Retrieving Data Between 2 Dates?

Jan 8, 2010

I want to create an application where I need to enter date to the ms access database.

I am a bit confused regarding how to make the user to enter date. The options avaliable are:

a. Shall I use a textBox?

b. Shall I go for 3 drop down lists?

or something else.

Some more questions:

1. what date format shall i use? (dd-mm-yyyy, dd-mmm-yyyy, etc, etc or anything else)

2. What datatype shall i use to store the date in the database?

3. What SQL query shall i use to retrieve the data between 2 dates?

let me know if there are multiple options available regarding this application.

I want to make this application as easy as possible for the user.

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.

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.

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#.

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.

ADO.NET :: Not Sure How To Do This Query In Linq To Sql

Sep 12, 2010

I need to figure out how to express this in linq to sql:I have one or more records that contain what is essentially a wildcard sql parameter, like '100_-___-2', which should match 100[any 1 char]-[any 1 char][any 1 char][any 1 char]-2, for example. Each login will have one or more of these 'datamasks' associated with it.I need to write a query in linq to sql that does something like:

select * from something
where fieldA = 'someValue' or fieldB = 'someValue'

so far, simple, but I also need to restrict the returned records to only those that match the user's 'datamasks'. I'm not sure exactly how to translate this to linq to sql... here is what a working query *without* the datamasks part looks like:

[Code]....

I need to tack on the datamasks part... can I do it right there in the same statement? or do I need to do a foreach loop on the datamasks records and append a new && condition for each one? hmmm... just thought of that as I was writing this.. I'll try that out. But I'm posting this anyway for more input... I guess that would look something like:

foreach (string mask in datamasks)
{
query = query.Where(item =>
System.Data.Linq.SqlClient.SqlMethods.Like(item.AccountNum, mask));
}

would that work? would each additional 'where' condition be 'appended' to the existing query definition?
