Asp.net invalid object name error when running query on SQL Server 2008

Question

I am trying to run a query, like the following:

SqlCommand putuser = new SqlCommand("INSERT INTO MainDB(NumberofEmployees) VALUES(4)", cn);

putuser.ExecuteNonQuery();

I get an Invalid object name error for the table named MainDB. I have checked the following:

1. The query works when running it in the Database.
2. I am connected to the correct database.
3. The Database does have a table with the name.

I am using Forms authentication. How do I make it so that anyone who access the application can make this insert to the Database. The insert is initially occurring after a user is created.

Answer 1

Are you using a connection string with Windows authentication or SQL Server authentication?

If you are using SQL Server authentication, use:

<add name="ConnectionString" 
     connectionString="Data Source=127.0.0.1; Initial Catalog=DataBase;Persist Security Info=True;User ID=user; Password=password

then you need to make sure the user has access to the data base and schema that you are using.

If you are using Windows authentication, the use

<add name="ConnectionString" 
     connectionString="Data Source=127.0.0.1; Initial Catalog=DataBase;Trusted_Connection=Yes;Persist Security Info=True;"/>

then you need to make sure that the user you are using in your App_Pool (the windows account that runs the application) is added as a login/user on the data base and has the rights to run queries.

EDIT

You can use SQL Server Management Studio to do this, step by step instructions can be found here and here
