Question

I’m trying to execute an Insert statement, but keep getting a Invalid object name error.

Here’s my code:

public string addNewComment(int userID, int pageID, string title, string comment)
{
    string query = "INSERT INTO dbo.nokernok_kommentarer (userID, pageID, commentTitle, comment) " +
    "VALUES ("+ userID +", "+ pageID +", '"+ title +"', '"+ comment +"')";

    adapter.InsertCommand = new SqlCommand(query, connection);

    //ExecuteNonQuery retuens number of rows affected
    int numRows = adapter.InsertCommand.ExecuteNonQuery();
    return numRows.ToString();
}

And here is my error message:

System.Data.SqlClient.SqlException:
Invalid object name
‘dbo.nokernok_kommentarer’. at
System.Data.SqlClient.SqlConnection.OnError(SqlException

development.DAL.nokernokDAL.addNewComment(Int32
userID, Int32 pageID, String title,
String comment) in
C:\Inetpub\wwwroot\naaf\DAL\nokernok.cs:line

Can anyone help me figure out why I get this error?

UPDATE

I should be using the correct database, because the following query works:

    public DataSet getSchools(string countyCode)
    {
        DataSet ds = new DataSet();
        string query = "SELECT * FROM nokernok_skoler WHERE kommunekode LIKE '" + countyCode.Substring(0, 2) + "%' ORDER BY enhetsnavn";
        adapter.SelectCommand = new SqlCommand(query, connection);
        adapter.Fill(ds);
        return ds;
    }

My connection string looks like this:

SqlConnection connection = new SqlConnection();
SqlDataAdapter adapter = new SqlDataAdapter();

// class constructor
public nokernokDAL()
{
    connection.ConnectionString = EPiServer.Global.EPConfig["EPsConnection"].ToString();
    connection.Open();
}

You’re probably in the wrong database. Include an initial catalog in your connection string:

Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername; ...
                            ^^^^^^^^^^^^^^^^^^^^^^^^^^

Or specify a three part name:

INSERT INTO myDataBase.dbo.nokernok_kommentarer
            ^^^^^^^^^^
