Command Execute

[JMM B]

In the code bellow, I tried:
this.sqlCommand1.ExecuteScalar();
this.sqlCommand1.ExecuteReader();
this.sqlCommand1.ExecuteNonQuery();
All work! But, What would be the best to choose for the mensioned Stored
Procedure?
thanks.

this.sqlCommand1.Parameters["@CustomerID"].Value = this.textBox1.Text;
this.sqlConnection1.Open();
this.sqlCommand1.ExecuteScalar();
this.label1.Text =
this.sqlCommand1.Parameters["@RETURN_VALUE"].Value.ToString();
this.sqlConnection1.Close();
this.label2.Text =
this.sqlCommand1.Parameters["@CompanyName"].Value.ToString();

ALTER PROCEDURE dbo.CountOrders

(
@CustomerID nchar(5),
@CompanyName nvarchar(40) OUTPUT
)

AS
SET NOCOUNT ON

DECLARE @OrdersCount int

SELECT @CompanyName = Customers.CompanyName, @OrdersCount =
COUNT(Orders.OrderID)
FROM Customers INNER JOIN Orders
ON Customers.CustomerID = Orders.CustomerID
WHERE (Customers.CustomerID = @CustomerID)
GROUP BY Customers.CompanyName

RETURN @OrdersCount

I would use the ExecScalar or ExecNonQuery.
Output parameters can stll be accessed. if you use the ExecNonQuery method,
or you can just return the count in the select statement and use the
ExecScalar method (first row, first col).

ExecuteNonQuery.
Don't return any unnecessary rowsets--they're expensive.
