DataSource Controls :: Check Time Of Day To Determine Shift To Return?

Mar 2, 2010

I have a table(ShiftCalendar) that lists a letter and a datetime:

Shift Date
A 3/2/2010 8:00:00 AM
B 3/2/2010 8:00:00 PM

I can run a select query that looks like this:

SELECT Shift
FROM ShiftCalendar
WHERE (Convert(nvarchar(10), GETDATE(), 101 = Convert(nvarchar(10), Date, 101))

This will return both values, but I need to to check the time of day to determine which Shift to return. I have been messing around with the IF ESLE and CASE but I can't find a way to tell the select statement what the time of day is.

DataSource Controls :: Return Unique Rows : T-SQL Query

Jun 11, 2010

I have an SQL database table like the following:

ID // Code // Shape

The ID is the integer identifier.

On one line the Code may be OX01 and shape Hexagon for example

Then the next line the code is still OX01 but the shape is Triangle.

What I want to do is be able to pull back data for every line that is equal to a unique Code column. in the above example OX01 Hexagon would be returned but not OX01 Triangle.

I've tried using SELECT DISTINCT but it brings back all records and doesn't filter them correctly.

I've considered having another column which could have Child/Parent data so that only the parent is returned but i'm sure there must be a better way of doing this.

DataSource Controls :: Linq To SQL Return All Results / Wild Sign?

Feb 2, 2010

I've been reading around, and it sounds like this is somewhat common, though I'm missing something.

I have my filtering rerouted to my codebehind via DataGridSource_Selecting event handler per

http://weblogs.asp.net/scottgu/archive/2007/09/07/linq-to-sql-part-9-using-a-custom-linq-expression-with-the-lt-asp-linqdatasource-gt-control.aspx

I have a set of controls on my page, Start Date, End Date, User, Status

Start and End Date are expected to always contain a value

User and Status I want to also have an 'All' option, where in it would return all results/not filter.

One method I can think of using for this, is the put the queries in a If scenario, where

if(user == All), use linq query B
if(user != All), user linq query A

where linq query A contains the filtering on Users, and linq query B does not.

What I have so far is

[Code]....

What I need

[Code]....

where User == ??,

can the control that populates that contain a wild card option as well? ie *, so that if user == Name, it filters on Name, or if user == *, it returns all?

Return Anonymous Type From LINQ Query In VB.NET

I am consuming an RSS feed to display on my website using a repeater control.

DataSource Controls :: SQL Query Return Incorrect Number Of Rows?

Mar 29, 2010

I am working on a small project. I ran the query below to get the maximum userid and increase it by 1 to create a new userid. However, when I run the query, it does not display the values that I enter into the database using insert statement. For example, if I open the table called login, I can see there are three records. If Irun the select statement, it only return one record which is the one that I enter manually when I first created the table. If I run the same select statement and give it a user id that I created, it returns the correct result.

DataSource Controls :: LINQ To SQL - Multiple Queries Doesn't Return Any Results

May 25, 2010

I am working on asp.net 3.5 and in MVC using Linq to SQL classes. In my MVC project i am calling stored procedure using linq to sql that conatin query joining two tables.Below is my code in Partial class

string userID)
{
ExecuteResult result = this.ExecuteMethodCall(this,
(MethodInfo)(MethodInfo.GetCurrentMethod())), userID);
return ((IMultipleResults)(result.ReturnValue));
}

In one of the controller i have made one more class

public class
MypostIndexData
{
public
IEnumerable<Thread> Thrds {
get;
set; }
public
IEnumerable<Reply> Repls {
get;
set; }
public MypostIndexData(IEnumerable<Thread>

VS 2010 - Can't Get Linq Query To Return Expected Results

Feb 13, 2014

I have a array list and am using like a database trying to search for ChildID and ParentID based on certain criteria.

My example below has the following keywords to search for:

Yellow, Mustard, Honey, Orange, Flame, Talisman

I also have a category volume value which I grab the first 2 characters to determine another filter.

My code isn't returning all matches with using 'Contains'. Right now it finds the 'Orange, Flame, Talisman'/AV record and returns 50, 28. My keywords also has 'Yellow, Mustard, Honey'/AV which should return 55 and 28 as well.

C# - Cannot Return Proper Model Into View When Doing A Join Linq Query

Mar 18, 2011

I have this code in my controller:

public ActionResult Index()
{
MembershipUser currentUser = Membership.GetUser();
Guid UserId = (Guid)currentUser.ProviderUserKey;
using (var db = new MatchGamingEntities())
{
var MyAccount = from m in db.Accounts..........

I want to be able to do a join query between my two tables Accounts and BankTransactions. This is a one to many relationship, there can be multiple BankTransactions per Account. I want to query this and display the account information including all the bank statements that are associated with it. I did a join in order to get it, but I am having trouble handling the model. I keep getting this error:

LINQ to Entities does not recognize the method 'System.Collections.Generic.List1[MatchGaming.Models.BankTransaction] ToList[BankTransaction](System.Collections.Generic.IEnumerable1[MatchGaming.Models.BankTransaction])' method, and this method cannot be translated into a store expression.

DataSource Controls :: Need To Check To See If Any Data Has Been Returned From The SQL Query?

Apr 15, 2010

I am trying to run the following SQL query

string strConString = ConfigurationSettings.AppSettings[ "conString" ];
myConnection = new OdbcConnection(strConString);
myConnection.Open(); // open connection
string strSelect= "select * from tbl_howells_product_data where title like" + "'" + strsearch + "%" +"'" + "order by product_id asc";
OdbcCommand myCommand = new OdbcCommand(strSelect, myConnection);
dtrReader=myCommand.ExecuteReader();

The problem is I need to check to see if any data has been returned from the SQL query, if there are no rows/ data returned by the query then I need to display a message to say that there aren't. I know that there isn't a 'number of rows method' for the dtrReader, so does anybody know how I could do this?

DataSource Controls :: Add A New Item To A LINQ Query?

I am trying to add a "New" field to the end of the list.
