How to call a stored procedure?


I have a stored procedure and I call it from C# code. However, I get an error as:

Could not find stored procedure 'xxx'

Below is the code and also run it from sql server itself using

exec dbo.proc_LogIn  @Username = 'user1', @Password = 'password1', @OutRes=1;

Can be permission issue from C# side?

Any help is appreciated.


public int Validate_Login(String strUserName, String strPassword)
            SqlConnection con = new SqlConnection(@"server=myMachine\SQLEXPRESS;integrated security=true");
            SqlCommand cmdselect = new SqlCommand();
            cmdselect.CommandType = CommandType.StoredProcedure;
            cmdselect.CommandText =  "[dbo].[proc_LogIn]";
            cmdselect.Parameters.Add("@Username", SqlDbType.VarChar, 50).Value = strUserName;
            cmdselect.Parameters.Add("@UPassword", SqlDbType.VarChar, 50).Value = strPassword;
            cmdselect.Parameters.Add("@OutRes", SqlDbType.Int, 4);
            cmdselect.Parameters["@OutRes"].Direction = ParameterDirection.Output;
            cmdselect.Connection = con;
            int Results = 0;
                cmdselect.ExecuteNonQuery();  //THIS LINE THROWS ERROR
                Results = (int)cmdselect.Parameters["@OutRes"].Value;
           catch (SqlException ex)
                lblMessage.Text = ex.Message;
                if (con != null)
            return Results;

The whole connection string should have this format:

Persist Security Info=False;Integrated Security=true;Initial Catalog=Northwind;server=(local)

Replace name of database Northwind with name of your database.

In place of you use server=myMachine\SQLEXPRESS you can use server=(local) if your SQL SERVER runs on the same machine as your program runs,
In other case you have to exactly specify your server path and name. For example with ip of server, where SQL Server runs and name of server.

I presume rather that you don't connect to the db where the stored procedure exists.
like the username connects to it's default db, which might be "master" by default ...

of course, it could also be permissions missing ...
add "Initial Catalog=FAQ" to the connection string (SqlConnection con)

and in the cmdselect.CommandText write the name of the procedure, ie:
cmdselect.CommandText = "proc_LogIn"
