通过脚本创建表以及如何运行脚本

Question

Ive got a couple of scripts that I need to run on my databse. So I have a few questions.

Im simply using Connection, CommandText,CommandType and CommandTimeout when opening a connection to the databse.

First question - Does anyone know if through this method, I can create permantent tables, not temporary tables?

Secondly - How would I run this file? Could I just set the file to be a parameter, and in the query run the parameter?

Thanks

Answer 1

In C#--

1. You can create both permanent and temporary tables this way.

2. Run the script as the CommandText of a command object.

Answer 2

You can do anything in a .NET SQL connection that you could do in a SQL script. As far as "running a file", you would need to load the file text into memory and execute the loaded text as a single command.

We do something similar in our application. Our database scripts are stored in SQL scripts. We load each file sequentially from disk into memory and execute it.

Example From MSDN : How to set parameters in the Query,

private static void UpdateDemographics(Int32 customerID,
    string demoXml, string connectionString)
{

    string commandText = "UPDATE Sales.Store SET Demographics = @demographics "
        + "WHERE CustomerID = @ID;";

    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        SqlCommand command = new SqlCommand(commandText, connection);
        command.Parameters.Add("@ID", SqlDbType.Int);
        command.Parameters["@ID"].Value = customerID;

        command.Parameters.AddWithValue("@demographics", demoXml);

        try
        {
            connection.Open();
            Int32 rowsAffected = command.ExecuteNonQuery();
            Console.WriteLine("RowsAffected: {0}", rowsAffected);
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }
}
