Good practice of CRUD by creating SqlDataAdapter when you cannot use Entity Framework episode 1 – sample and video

Not all the Database Engines can support Microsoft Entity Framework no doubt Entity Framework is one of the best persistent Framework in the programming world today.

 

1. Create a Web Project.

 

2. Create a class, I call it ClassSqlAdapter.

 

3. Copy the source code from SqlDataAdapter.InsertCommand Property and paste it in ClassSqlAdapter.

 

public static SqlDataAdapter CreateCustomerAdapter(

    SqlConnection connection)

{

  SqlDataAdapter adapter = new SqlDataAdapter();

 

  // Create the SelectCommand.

  SqlCommand command = new SqlCommand(“SELECT * FROM Customers “ +

      “WHERE Country = @Country AND City = @City”, connection);

 

  // Add the parameters for the SelectCommand.

  command.Parameters.Add(“@Country”, SqlDbType.NVarChar, 15);

  command.Parameters.Add(“@City”, SqlDbType.NVarChar, 15);

 

  adapter.SelectCommand = command;

 

  // Create the InsertCommand.

  command = new SqlCommand(

      “INSERT INTO Customers (CustomerID, CompanyName) “ +

      “VALUES (@CustomerID, @CompanyName)”, connection);

 

  // Add the parameters for the InsertCommand.

  command.Parameters.Add(“@CustomerID”, SqlDbType.NChar, 5, “CustomerID”);

  command.Parameters.Add(“@CompanyName”, SqlDbType.NVarChar, 40, “CompanyName”);

 

  adapter.InsertCommand = command;

 

  // Create the UpdateCommand.

  command = new SqlCommand(

      “UPDATE Customers SET CustomerID = @CustomerID, CompanyName = @CompanyName “ +

      “WHERE CustomerID = @oldCustomerID”, connection);

 

  // Add the parameters for the UpdateCommand.

  command.Parameters.Add(“@CustomerID”, SqlDbType.NChar, 5, “CustomerID”);

  command.Parameters.Add(“@CompanyName”, SqlDbType.NVarChar, 40, “CompanyName”);

  SqlParameter parameter = command.Parameters.Add(

      “@oldCustomerID”, SqlDbType.NChar, 5, “CustomerID”);

  parameter.SourceVersion = DataRowVersion.Original;

 

  adapter.UpdateCommand = command;

 

  // Create the DeleteCommand.

  command = new SqlCommand(

      “DELETE FROM Customers WHERE CustomerID = @CustomerID”, connection);

 

  // Add the parameters for the DeleteCommand.

  parameter = command.Parameters.Add(

      “@CustomerID”, SqlDbType.NChar, 5, “CustomerID”);

  parameter.SourceVersion = DataRowVersion.Original;

 

  adapter.DeleteCommand = command;

 

  return adapter;

}

 

4. Create a Webform if you do not have one.

 

5. Add a Button Webcontrol.

 

6. Paste the following code into the click event.

 

protected void btnInsert_Click(object sender, EventArgs e)

{

  SqlConnection conn = new SqlConnection(“Data Source=.;Initial Catalog=northwind;Integrated Security=True”);

  conn.Open();

  SqlDataAdapter da = ClassSqlAdapter.CreateCustomerAdapter(conn);

 

  da.InsertCommand.Parameters[0].Value = “1000”;

  da.InsertCommand.Parameters[1].Value = “Microsoft”;

 

  da.InsertCommand.ExecuteNonQuery();

}

 

or

 

protected void btnInsert_Click(object sender, EventArgs e)

{

  SqlConnection conn = new SqlConnection(“Data Source=.;Initial Catalog=northwind;Integrated Security=True”); 

  conn.Open();

  SqlDataAdapter da = ClassSqlAdapter.CreateCustomerAdapter(conn);

  da.InsertCommand.Parameters[“@CustomerID”].Value = “1000”;

  da.InsertCommand.Parameters[”@CompanyName”].Value = “Microsoft”;

  da.InsertCommand.ExecuteNonQuery();

}
