Avoid Error When No Results From Entity Query

Mar 14, 2011

I have a simple Entity query:

[code]....

I then check whether one of the result values is more recent than six months ago using an if..then like so:

If rhcexists.First.SignatureDate > Date.Today.AddMonths(-6) Then
End If

However, if there are no results returned this will return an error. Is there a way for me to tell it to act as if the date is older than six months if there is no value at all? e.g., could I in pseudo do something like:

If Exists(rhcexists.First.SignatureDate, Date.Today.AddMonths(-8)) > Date.Today.AddMonths(-6) Then
End If

Entity Query - Combine Into One And Avoid Merging The Results

Nov 6, 2010

I can't seem to figure out how to write this query properly. I've tried various combinations but nothing's worked yet. Below is the relevant portion of my database model: I need to select the products that match a given Category and Group, and that match a given Year, Make, Model, submodel. This I've done below:

ItemList = From P In gDataContext.Products.Include("Groups").Include("Groups.Category1").Include("LookupYearMakeModels") From G In P.Groups Where G.Category = Cat And G.Grp = Group From Y In P.LookupYearMakeModels Where Y.Year = YMM.Year And Y.Make = YMM.Make And Y.Model = YMM.Model And Y.Submodel = YMM.Submodel Select P

I now also have to select products that match the Category, and Group but are Universal (Product.Univeral = True). I'm currently writing two queries, the one above and the one below. I'm merging the results of the two by simply using ItemList.AddRange(ItemList2) ItemList2 = From P In gDataContext.Products.Include("Groups").Include("Groups.Category1") where P.Universal From G In P.Groups Where G.Category = Cat And G.Grp = Group Select P But I want to combine both queries into one and avoid merging the results. How can I do it?

Trying To Compare LINQ-to-Entity To Date Results In Error

Mar 14, 2011

I have a simple If..Then like so:

If rhcexists.First.SignatureDate > Date.Today.AddMonths(-6) Then
End If

rhcexists is a simple query to the Entity Model:

Dim rhcexists = From p In dbContracts.Signatures _
Where p.StudentID = CStr(Session("people_code_id")) _
And p.ContractType = "rhc" _
Order By p.ID Descending _
Select p

Problem is that this comparison results in an error:

LINQ to Entities does not recognize the method 'System.Object get_Item(System.String)' method, and this method cannot be translated into a store expression.

This is occurring on the If clause. Any ideas why this occurring and how I can fix it?

I am using ASP.NET 4, EF 4, and VS 2010 SP1.

ADO.NET :: [Entity Framework] Strange Error Executing A Sql Query

Nov 29, 2010

I have a strange error, I've tried to search for it before writing this post but I wasn't able to find out a solution yet.

I'm executing a query using ExecuteStoreQuery against a MySQL database, but it throws an exception reporting that there's a syntax error in my SQL.

I've tried to copy&paste the sql query into the MySQL tool and it works nicely, giving the correct results.

I've tried to open manually the connection and using CreateCommand to use it the "old way".

My query is a bit long, 4000 chars more or less, could it be the problem?

Entity Framework CTP5 - Code First - Nested Query Error

I have the following classes:

public class Category
{
public int CategoryId { get; set; }
public string Name { get; set; }
}
public partial class CategoryMap : EntityTypeConfiguration<Category>
{
public CategoryMap()

this.HasKey(c => c.CategoryId);
this.Property(c => c.Name).IsRequired().HasMaxLength(400);
}
}
public class MyObjectContext : DbContext

public DbSet<Category> Categories { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)

DbDatabase.SetInitializer<MyObjectContext>(new DropCreateDatabaseIfModelChanges<MyObjectContext>());
using (var context = new MyObjectContext("NopSqlConnection"))
{
var query1 = from c in context.Categories

var test1 = query1.ToList(); //works fine
var query2 = from c in context.Categories
where query1.Contains(c.CategoryId)
orderby c.Name descending
select c;
var test2 = query2.ToList(); //throws the exception

In MVC And Entity Framework, How To Avoid Duplicate Rows

Mar 7, 2011

I'm new to ASP.NET MVC and I'm trying to implement an address manager.I'm using Linq2Entity Framework. I've got a table with contacts and one with phone numbers. These two tables are linked by a contact_has_phone_number table. The Entity Framework enables me to get all phone numbers that are assigned to one contact. This is done by calling contact.PhoneNumbers which returns a collection of phone numbers.

Avoid Getting Data From Entity Framework's Cache

Jun 9, 2010

I have a weired problem. One of the pages in my application show's status of tasks in a table. I am using entity framework ( entity to object) to do all the data handling with DB. I noticed that even though the status is updated in DB, its not reflected on my webpage even after continuous refresh! If i stop the server and start the application again (currently running on VS2008 dev server) the updated data is displayed!

Am I seeing the cached data? how do I prevent this from happening?

How To Avoid Clashes With Existing Entity ID's When Deserializing And Importing EF Entities

Feb 11, 2011

I have an ASP.NET 4 web app that is using the Entity Framework to hold, amongst other things, a hierarchical structure of items that is used for features such as navigation.

One of the functions of the application allows the export of a particular branch of the hierarchy tree to XML, generated using a DataContractSerializer. Once exported, the intention is that the XML can then be uploaded to another instance of the same app, deserialized back into EF objects and then added to the data model on the second server.

When I try and import data in this way, I'm finding that I see the following error:

The object could not be added or attached because its EntityReference has an EntityKey property value that does not match the EntityKey for this object.

Taking a closer look at the XML that is generated by the serializer, I can see that the entity key is among the items that has been serialized. Since I'm importing entities that originate from a different database, some of the ID's clash.

What I'd ideally like to be able to do (unless I'm missing something here) is attach the imported entities to an object context and reset the ID's of the objects being imported.

Is there a smart way to do this? Do I simply have to set the ID for each of my imported entities to 0, attach them to the object context and then save changes?

DataSource Controls :: Accessing FK From A Query Via Entity Query

Jan 21, 2010

I've got a query such as

Dim MediaQuery =
From m
In dB.DOWNLOADS _Where m.ID = id _Select

which returns a record from the database. One of the fields in the record is a FK to another table. I need to read this value to be able to set a dropdown based on the ID but I can't work out how to access it. For a standard record I can just do the following txtTitle.Text = MediaQuery.FirstOrDefault().TITLE

However with the foreign key it doesn't work like that. I've tried drpGroup.SelectedIndex = MediaQuery.FirstOrDefault().DOWNLOAD_GROUPS.ID where DOWNLOAD_GROUPS is the FK field but it returns Object reference not set to an instance of an object. If you're simply wanting to read some values from a single db record in the entitiy framework and one is a foreign key how should I go about getting the value?

C# - Avoid Query String That Appears In The Address Bar?

Dec 11, 2010

I have applied a filter on a page using drop downs.

When i click on apply filter.. the page gets filtered. Now i click on the edit of filtered result.. which redirects me to another page.

I want to send the selected data from the drop downs from the filter page to the redirected page.. and again to the filter page.. to retain the filter. I am doing all this by sending the values in Query string.

Is there anyway.. i can avoid the visibility of the query string in the address bar and still get the values and required result.

C# - Avoid Double Control Search In LINQ Query?

Jun 23, 2010

I have a Dictionary<string, bool> where key - control's ID and value - it's visible status to set:

var dic = new Dictionary<string, bool>
{
{ "rowFoo", true},
{ "rowBar", false },
...
};

Some of controls can be null, i.e. dic.ToDictionary(k => this.FindControl(k), v => v) will not work because key can't be null. I can do next:

dic
.Where(p => this.FindControl(p.Key) != null)
.ForEach(p => this.FindControl(p.Key).Visible = p.Value); // my own extension method

but this will call FindControl() twice for each key. How to avoid double search and select only those keys for which appropriate control exists? Something like:

var c= FindControl(p.Key);
if (c!= null)
return c;
but using LINQ.

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.

C# - Why Is SQL Query Returning Duplicate Results

Dec 1, 2010

The SQL is below - each result is coming up 3 times rather than just once.

SELECT Consignments.LegacyID, TripDate, CollectionName, DeliveryName, Pallets, Weight, BaseRate, Consignments.FuelSurcharge, AdditionalCharges, BaseRate * Quantity AS 'InvoiceValue', Consignments.Customer, InvoiceNumber,
CASE
WHEN child.LegacyID = Consignments.Customer THEN child.LegacyID
WHEN parent.LegacyID = Consignments.Customer THEN parent.LegacyID
ELSE this.LegacyID
END AS 'InvoiceAcc'
FROM SageAccount this
LEFT JOIN SageAccount parent on parent.LegacyID = this.InvoiceAccount
LEFT JOIN SageAccount child on this.LegacyID = child.InvoiceAccount
JOIN Consignments on (Consignments.Customer = this.LegacyID AND this.Customer = 'True')
OR (Consignments.Customer = parent.LegacyID AND parent.Customer = 'True')
OR (Consignments.Customer = child.LegacyID AND child.Customer = 'True')
WHERE (this.LegacyID = @Customer) AND (TripDate BETWEEN @fromdate AND @todate) AND (InvoiceNumber IS NOT NULL)

The SQL was given to me for another similar query, but this time I have modified it to try to use it for the query I'm doing now, so I'm assuming that I'm doing something stupid.

LINQ-to-SQL Query Returning No Results?

Mar 5, 2011

I have a query using LINQ-to-SQL. It queries an underlying database table Rooms. It uses Where conditions to narrow down the results, namely:

Gender.
Current Occupancy < Max Occupancy
Available Flag is Checked

I know this should return results but it keeps returning an empty set. Any ideas? Code is below

Dim selectedHalls = (From sh In dbHalls.Rooms _
Where sh.gender = Session("gender").ToString _
Where sh.max_occupancy > sh.current_occupancy _
Where sh.is_available = 1 _
Select sh.building_name).Distinct()

UPDATE: I've verified that the issue is with the statement where sh.is_available = 1, which doesn't make sense since this is a bit field.

Access :: Using Results From A Sql Query In A Variable?

Oct 2, 2010

I've managed to use my MS Access database with repeaters and gridviews in my website. Basically, printing the result of a query directly to the website seems easy enough using something like this :

[Code]....

After quite a bit of googling this seems to be a common way to do this. My question then seems kinda silly.

I want to use some of the data from the query in for example a variable without sending the data to a repeater or gridview and so on. Say I just want the username and a password from a database and want to store the username in one variable and the password in another for further use in the code. What do I do?

ADO.NET :: How To Alphabetise The Results From A Linq To Sql Query

Jan 26, 2011

I can't seem to change the order of the results coming back from a linq to sql query, I want just to return the distinct values from the field x.manufacturer in alphabetical order, this is what I have and it isn't working:

public IQueryable<string> Dropone()
{
return (from x in CAT.CatalogueDatas
where x.Parent == null
orderby x.Manufacturer
select x.Manufacturer).Distinct();
}

Currently I get the distinct values in non-alphabetical order, in fact I'm not sure what order they're coming out in, don't think it's the order in which they appear though.

On one page you can enter two user id's and get a side by side comparison of their roles in our (custom app) system.

I often use it to add roles when I'm setting up new users. After running the query, if i change a role and run the query again it will not show updated results. It's being cached somehow. I have to go to another page and come back and them run the query to get updated results.

How can avoid having to navigate away to get the updated query results displayed.n

Concatenating Results From SQL Query And NULL Columns?

May 11, 2010

I need to concatenate several columns of a table into a single value, then show that value in an asp dropdownlist. The SQL code I'm issuing is as follows:

SELECT UserID, CustomerNum, UserName + ' - ' + UserAddress + ',' + UserCity + ' ' + UserState AS UserInfo
FROM Users
WHERE (CustomerNum = @CustomerNum)
ORDER BY UserName

I then set 'UserInfo' as the text field in the dropdownlist.This generally works, except occasionally one of the columns in the database is null (for example, UserState). When that happens, the entire concatenation is null, and I get an empty entry in the dropdownlist.

Is there something in SQLServer that will allow me to ignore those NULL results, or will I have to code something up in the DataBind event?
