Put Item in database #c

Posted By:      Posted Date: October 20, 2010    Points: 0   Category :ASP.Net


When i put an item in my database in ASP.net #c i get this problem:

The parameterized query '(@pmSearchId nvarchar(4000))INSERT INTO aspnet_search(SearchId)V' expects the parameter '@pmSearchId', which was not supplied.

In my default page i wrote this :

LINQ to SQL - Validating if item is in Database, but if item is not items not inserting into databas



I am new to this, so bear with me.  I am writing an application in C# that uses LINQ to validate a datacontext off a textbox to see if the record exists already.  If the record does exist I inserted an if statement to advise the user that the record exists, if the record does not exist I would like to allow the record to be added to the database.  If I take out my else statement everything works fine as far as inserting goes, but I do not want to allow inserts in this scenario.  I have tried moving the if and else statement to different parts of the code but can't quite figure this one out.  Any help would be apprecaited, attached is the code.  This code is set to a button press.  As a matter of fact, if you see any other errors along the way please feel free to point them out. 



    protected void enterBTN_Click(object sender, EventArgs e)
        //make new data context

        SHCDataContext insNewAll = new SHCDataContext();
        //LINQ to check if customer exists in database
        var checkExisting = from c in insNewAll.Customers
                            where c.custLastName.Contains(custLastNameTB.Text.ToString())
                            select c.custLastName;
        //make list to store values

Multiple database support with Entity Framework

One of the features introduced in Entity Framework is being database independent. Which mean each database provider can support Entity Framework by implementing its provider.

This feature allows you build applications independent from the underplaying database provider. In this post I'm going to show how to build an application that support multiple databases using same conceptual model made by Entity Framework.

SQL Server Database Transaction

A transaction is a group of SQL commands executed together as a single component of work to be accomplished. If all of these commands succeed, then a transaction is committed - the changes to the data are made final. If any of the commands within a transaction fail, then the entire transaction is cancelled, or in SQL Server terms, the transaction will be rolled back.

Transactions are one of the things that keep your data safe, but they're not necessarily easy to understand. Here's some help:

Reading and Writing Images From a Windows Mobile Database using UltraLite 10(C#)

Periodically I get a request for information on how to read and write binary data to a database running on Windows Mobile. If you search the Internet you can typically find examples that are available on Windows Desktops or allow you to read and write to a local file system. The problem is that it can take a bit of work to get this code to work on Windows Mobile accessing a database.

Ultimately you might be asking, why would I want to store and image in a database? Well in an environment where you synchronizing data between a local mobile database and a consolidated (central) database this can be extremely useful. Imagine if an insurance adjuster went to an accident scene, took a picture of a damaged car, loaded it into his Windows Mobile database and then replicated that image up to the Insurance headquarters for approval. All of this could be done in a very short period of time when using images in the database. Another good example might be a doctor who was waiting for a patient chart to become available. If you could store the image in a database this chart could be sent down to the doctor's device once it became available.

For this article I am not going to get into how to synchronize the images to and from a remote and central database as this is typically fairly straightforward when using a data synchronization technologies like MobiLink
