How to connect to a remote oracle database with Visual Studio?
I know how to create the connectionSting in web.config. I wonder if I can connect to an oracle database when creating a LINQ class so that tables will show in the Server Explorer.
I can't connect to both 9i and 10g from asp.net,when i installed 9i client in a machine which already contain 10g xpress edition and no 10g client 9i client used to connect 9i db in another machine. Both 9i and 10g can be connected with TOAD. i got the following error msg from the asp.net application. System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.
I want to insert some values (from asp.net web application) in a table on oracle DB that hosted on a machine rather than the machine that hosts the asp.net 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 just want to be able to connect to a remote MySQL database on my ASP.net c# website running on localhost.
It's so I can grab some records, and insert them into my SQL server database. Do I need to download any drivers? And how do I connect and fetch records?
oledbCon.ConnectionString = "Provider=MySqlProv; Data Source=localhost; Initial Catalog = AnymoreComputers; User id=WeakUser2;Password=1234";
my site is working and running wrote in c# and mssql 2005,
now i want to make it run with mysql.....i converted all my data base...and created the same users (same names)
anc copied all to my sql .
the question is how do i connect to mysql wit c# ......
my regular connection for mssql :
oledbCon.ConnectionString = "Provider = SQLOLEDB.1; DATA Source = (local); Initial Catalog = test1; Integrated Security = SSPI; User ID=WeakUser2;Password=1234"; the connection to mysql : oledbCon.ConnectionString = "Provider=MySqlProv; Data Source=localhost; Initial Catalog = test1; User id=WeakUser2;Password=1234";
this connection doesnt works ... where is my mistake ? what hsould i do ... ?
and this is the error ig get when i run my solution :"The ConnectionString property has not been initialized."
I have 2 servers. the database server (DB1) which has sqlserver installed and the application server (WEB1) which has my web application. They are both on the same network and both have the same administrator login.
My web application on the application server needs to access the database on the database server. sqlserver is set to mixed mode in security. i created a random sqlserver user login that can only access my database and set it as the db owner. I use the username and password for this in my connection string. when i run my web application i can read information but i cant write to the database. My app is using windows thentication. I have set my NT AUTHORITYNETWORK SERVICE account to db_owner for my database as well... grabbing at straws!
Question 1: When my application talks to sqlserver does it use the administrator login or the NT AUTHORITYNETWORK SERVICE account which i got from using windowsidentity.getcurrent()?
Question 2: If I use ASP.Net impersonation, what does this do exactly? Because if i run the ndowsIdentity.GetCurrent() i get the username that i specified. How does this tie in with my connection string?
Question 3: If I dont use impersonation what and how do i have to configure sqlserver to accept my insert/update requests? Do i need to work with the NT AUTHORITYNETWORK SERVICE? or can i just use my user login? What do i need to add or remove from my connection string? (see below).
My code is to update a record if it already exists in database else insert as a new record. My code is as follows:
protected void Button3_Click(object sender, EventArgs e) { OdbcConnection MyConnection = new OdbcConnection("Driver={MySQL ODBC 3.51 Driver};Server=localhost;Database=testcase;User=root;Password=root;Option=3;"); MyConnection.Open(); String MyString = "select fil_no,orderdate from temp_save where fil_no=? and orderdate=?"; OdbcCommand MyCmd = new OdbcCommand(MyString, MyConnection); MyCmd.Parameters.AddWithValue("", HiddenField4.Value); MyCmd.Parameters.AddWithValue("", TextBox3.Text); using (OdbcDataReader MyReader4 = MyCmd.ExecuteReader()) { //** if (MyReader4.Read()) { String MyString1 = "UPDATE temp_save SET order=? where fil_no=? AND orderdate=?"; OdbcCommand MyCmd1 = new OdbcCommand(MyString1, MyConnection); MyCmd1.Parameters.AddWithValue("", Editor1.Content.ToString()); MyCmd1.Parameters.AddWithValue("", HiddenField1.Value); MyCmd1.Parameters.AddWithValue("", TextBox3.Text); MyCmd1.ExecuteNonQuery(); } else { // set the SQL string String strSQL = "INSERT INTO temp_save (fil_no,order,orderdate) " + "VALUES (?,?,?)"; // Create the Command and set its properties OdbcCommand objCmd = new OdbcCommand(strSQL, MyConnection); objCmd.Parameters.AddWithValue("", HiddenField4.Value); objCmd.Parameters.AddWithValue("", Editor1.Content.ToString()); objCmd.Parameters.AddWithValue("", TextBox3.Text); // execute the command objCmd.ExecuteNonQuery(); } } }
I am getting the error as: ERROR [42000] [MySQL][ODBC 3.51 Driver][mysqld-5.1.51-community]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'order,orderdate) VALUES ('04050040272009',' &' at line 1
The datatype for fields in table temp_save are:
fil_no-->INT(15)( to store a 15 digit number) order-->LONGTEXT(to store contents from HTMLEditor(ajax control)) orderdate-->DATE(to store date)
I'm having problems trying to connect to a remote debugger for VS2008-SP1.I'm trying to debug an ASP.NET application on a Win2k8 VM. The host PC (WinXPsp3) running Visual Studio is connected to an AD domain, and is logged in with a domain account. The VM is not connected to the domain and is logged in with the local Administrator account.The VisualStudio remote debugger requires authentication in both directions, so I would normally add my domain account as a local admin on the VM and allow debug permissions for that user.Since the VM is not on the domain, I can't add my domain account as a local admin. What can I do to get remote debugging going between my PC and the VM?
