Then I have prepared a model,controller,view for accessing and displaying the data. I am using LINQ o get the data from database but getting the exception:" A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)" I have also installed the MYSQL connector. provide me the solution to access the data using MYSQL and LINQ in MVC application
I have used ASD.NET code using SQL Database for Transaction operation successfully. By changing the Database Code to interface with MYSQL an Error occurs. If I remove the Transaction Code from within the the application, it works OK by displaying the MYSQL data (Read Only) in the layout of the application. I am using Mysql Essential-4.1.22-win32 and MYSQL Connector ODBC-3.51.2. My objective is to EDIT the MYSQL Data.

I want to retrieve data from MySql database and display it in gridview in asp.net.I want to retrieve data from two tables which has no common fields to link.Is there any possible way to display in gridview?
I'm working on an external web site (in DMZ) that needs to get data from our internal production database.
All of the designs that I have come up with are rejected because the network department will not allow a connection of any sort (WCF, Oracle, etc.) to come inside from the DMZ.
The suggestions that have come from the networking side generally fall under two categories -
1) Export the required data to a server in the DMZ and export modified/inserted records eventually somehow, or
2) Poll from inside, continually asking a service in the DMZ whether it has any requests that need serviced.
I'm averse to suggestion 1 because I don't like the idea of a database sitting in the DMZ. Option 2 seems like a ridiculous amount of extra complication for the nature of what's being done.
Are these the only legitimate solutions? Is there an obvious solution I'm missing? Is the "No connections in from DMZ" decree practical?
Edit: One line I'm constantly hearing is that "no large company allows a web site to connect inside to get live production data. That's why they send confirmation emails". Is that really how it works?
I just moved to a new 2008 64 Bit Server. We are using MySQL, now also the 64 Bit version. Now I found out that there is a 64 Bit ODCB Driver, but not an 64 Bit Net/Connector.
Is that an issue or is the .NET Connector by default 32 and 64 Bit?
I want to use MVC 2 with MySQL database. Is it possible?because my shared hosting limits the size of SQL Server database, but there is no limit on Size of MySQL database.MySQL seems to take less disk space than SQL Server database which is costly on the Internet.

i done one web application in this application i need to transfer the data from one table to another automatically when the time is 10.00PM. i need to write this function sepearte time function not in page load function.the user select any of page the data should be transfer from one to another without page load only using time control function..
I need to develop an application, which will get records (orders) from one application and process them. The updates to this records (order updates) will be sent back to the source application for end customer reference. I'm planning to achieve this data synchronization at the database level using triggers and stored procedures to insert database between the 2 databases.
But, the issue is I have to deploy this application in 3 different customer sites and I have to change the database names (cannot use the same database name) in each deployment manually. Because of this deployment issue, I was thinking of handling this within the asp.net application where I can store the db name in the database and then build the query within the application, but I dont want to do it as building queries like that doesnt look very professional.
I did all the instructions which are in the following link: [URL] in order to do a connection between MySQL database and ASP.NET but I did not successed. Sometimes, it told me that I have a mistake in the <asp: button> and sometimes it told me that I did a mistake in calling (addImage) method. And this is my whole code:-
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="HW5._Default" %> <script> public class DataAccess { private string _strConn = @"Driver= {MySQLODBC 3.51 Driver};SERVER=localhost;DATABASE=test1;"; private OdbcConnection _objConn; public DataAccess() { this._objConn = new OdbcConnection(this._strConn); } // This function adds the Images to database public string addImage(timestamp id, byte [] data,string extension) { string strSql = "SELECT * FROM File"; DataSet ds = new DataSet("Image"); OdbcDataAdapter tempAP = new OdbcDataAdapter(strSql,this._objConn); OdbcCommandBuilder objCommand = new OdbcCommandBuilder(tempAP); tempAP.Fill(ds,"Table"); try { this._objConn.Open(); DataRow objNewRow = ds.Tables["Table"].NewRow(); objNewRow["Extension"] = extension; objNewRow["Data"] = buffer; objNewRow["ID"] = id; ds.Tables["Table"].Rows.Add(objNewRow); // trying to update the table to add the image tempAP.Update(ds,"Table"); }.....................................
I'm trying to apply this example to my website.They use SQLServer in this link[URL]string sql = "Select * from Country Where Country_Name like @prefixText";i have to change the last part( like @prefix ) so that it wont give any errors for MySQL
