I am new to LINQ. I have a GridView which I am populating using LINQ. My LINQ statement is taking query string from previous page. The query string is in string format. Here is the code:
I'm currently developing a web application using SQL Server 2005, ASP.Net MVC, ASP.Net SQL Membership Provider (for authentication and authorisation), and Linq to SQL. Everything works great and is running as planned in the development environment.However, the production environment has a SQL Server 2000 installation, and we are unable to obtain a copy of SQL Server 2000 to use in development.Upon deploying the web application to the the production environment, what options do I have for migrating the database (schema + data) from 2005 to 2000?
I'am developing a web application with VS2010 Entity Framework and SQL Server Express. This application will be deploiyed in a server with SQL Server 2008 (not express) It is possible? What changes (if needed) i need to do?
We are building an extranet loan status check website using ASP.NET MVC with a WCF backend. Its a pretty standard design with the MVC site using a WCF service reference to get customer objects. The ervice uses an Oracle backend + http binding, and won't be hosted on the same server as the MVC site (so we can't use tcp binding to reduce latency).
The problem we encountered is that every call to the service is resulting in a 7-8s response time which is unacceptable for an extranet site and much higher than the 2s magic mark. The service method(s) call 12 stored procedures to create the customer object. The database is, unfortunately, denormalized (we can't change it as its also used by other inhouse production systems) so most of the calls are basic select statements which populate the customer object and its associated objects. The service proxy is properly opened and closed/disposed in the MVC actions so there are no instances of any service connection leaks. A new client proxy is created for every request (i.e., we are not using the singleton pattern for the service). how we can speed this up ?
To write a join query with or condition. It means a query has two inner join, here it is possible to fetch the records, if one inner join is true and other is false. I got a record when only two join conditions are true.
I'm trying to build a linq2Entity/gridview function for a forum, that draws data from multible tables.The result should be: Get the latest 10 threads that user(xx) has replyed in, that is not disabled or has a subject that is not allowed.Include information on the last post, thread owner user, and last post user, in each thread. ere is my code... is returns the correct threads and some that should not be there.
I have some text files I need to parse in order to display my data, and what I have now are two text files with lots of redundant data. Instead of this I would like to replace the redundant data with a number referencing the text in another text file.
I am interested in learning how to develop a custom asp.net ajax gridview, and I have obtained some books on the subject, but would still like a quick answer for a question: When developing a custom ajax server control, can I somehow use jquery for the client-side part of the control? Are there any collisions with ASP.NET AJAX framework and are there special requirements (e.g. only available for .NET 4.0 etc.)?I would also appreciate any suggestions on resources from which I can learn more about developing a custom asp.net ajax server control from scratch.
Most of my experience has been developing 'webpages'. Presently, I am developing a mozilla extension which does not support web services, others have suggested to use XMLHttpReqest instead. I have the client side code for it but have no idea on how to write the server side for it.
TABLE 1 SELECT I.STUNA ,S.SNO ,SUM(B.AMT * Y.YEAR) AS AMT FROM STUDENT S LEFT JOIN INFO I ON S.SNO = I.SNO LEFT JOIN BONUS B ON S.SNO = B.SSNO LEFT JOIN YEAR Y ON S.SNO = Y.SSNO STUNA SNO AMT JOHN A 10 LISA B 20 ALLEN C 100
TABLE 2 SNO AMT A 1 B 2 C 3 D 5
I WANT TO HAVE RESULT LIKE THIS (TABLE1 + TABLE2)
STUNA SNO AMT JOHN A 11 LISA B 22 ALLEN C 103 EDDIE D 5
I TRIED USE THIS QEURY
SELECT I.STUNA ,S.SNO ,SUM(B.AMT) AS AMT FROM STUDENT S LEFT JOIN INFO I ON S.SNO = I.SNO LEFT JOIN BONUS B ON S.SNO = B.SSNO LEFT JOIN ( SELECT SNO, SUM(AMT) AS AMT FROM TABLE2 GROUP BY SNO ) T2 ON S.SNO = T2.SNO GROUP BY I.STUNA,S.SNO THE RESULT IS STUNA SNO AMT JOHN A 11 LISA B 22 ALLEN C 103
THE "EDDIE" WAS MISS. ALSO I TRY USE CROSS JOIN... THE RESULT IS STILL NOT CORRECT.
i need to join two tables in different databases, how it can be done??? and if i want to use sqldatasource control to bind results to some data-bound control how can I configure my sqldatasource control???
I have faced the peculiar case in Sql server's Inner join. I have 2 tablesFor example:Table Name: A and B I have shown the below code.
Select * From A Inner Join B ON A.JobCode =B.JobLookupID
This select statement return 500000 records but both table did not have that much recordsI have shown the Records in every table:A=19396 and B= 25366 records.How it will return more then 5 lakh records in above select statemenet?. Please let me know if any one faced this issue earlier?
t1 : id FirstName Age 1 Joe 22 2 James 33 3 Bart 28 t2: id LastName 1 Coymer 2 Manes
I can combine the data from the two tables using an inner join.
1 Joe 22 CoyLap 2 James 33 Manes
The problem though is that the person "Bart" with an Id of 3 is left out because he does not have an entry in the second table.So how can I include Bart in the output in such a way that the output might look like this:
1 Joe 22 CoyLap 2 James 33 Manes 3 Bart null null
Or spaces can instead appear for Barts last name and age instead of null.Basically I just need Bart in the output as well even though he has no age and last name.
Im trying to join these 2 Containstables sq lstatements together...but I dont know how..they both Containstables...and have no relation to each other....but I need to search both tables.How do I join these two statements?

I have a table with logentries (tblLog) for items (tblItem) (one-to-many relationship). How can I select say the id and date for the latest logentry when I select a record from the tblItems table? In other words I want a result set with all columns from the tblItem table and also some additional columns from the tblLog table (LogId, Date, Event) for each row selected from the tblItem table. How can I do this?
tblLog LogId ItemId Date Event tblItem ItemId Field select tblItem.*, tblLog.LogId, tblLog.Date, tblLog.Event FROM tblItem tblItem JOIN tblLog tblLog ON?
I am building an object from multiple datasources. Does anyone know whether this is possible in NHibernate and how. I should mention that one source is SQL the other ORACLE.
