Question

Hi guys

In sql server 2005 i write the following query 

ALTER proc [dbo].[JeddahSalesAll]

as

SELECT     ROW_NUMBER() OVER (ORDER BY dbo.[Jeddah-Live$Sales Header].No_) AS [S.N], dbo.[Jeddah-Live$Sales Line].[Document No_] AS 'OrderNo', 

dbo.[Jeddah-Live$Sales Header].[Bill-to Name] AS 'CustomerNo', dbo.[Jeddah-Live$Sales Line].Area AS 'Shippment Type', dbo.[Jeddah-Live$Sales Line].Description AS 'Description', 

dbo.[Jeddah-Live$Sales Header].[Pump No_] AS 'PumpNo', CAST(ROUND(dbo.[Jeddah-Live$Sales Line].Quantity, 0, 1) AS int) AS 'Required Qunatity', 

CAST(ROUND(dbo.[Jeddah-Live$Sales Line].[Quantity Shipped], 0, 1) AS int) AS 'Shipped Quantity', CAST(ROUND(dbo.[Jeddah-Live$Sales Line].[Outstanding Quantity], 0, 

1) AS int) AS 'Outstanding Qunatity '

FROM         dbo.[Jeddah-Live$Sales Header] INNER JOIN

dbo.[Jeddah-Live$Sales Line] ON dbo.[Jeddah-Live$Sales Header].No_ = dbo.[Jeddah-Live$Sales Line].[Document No_] AND 

dbo.[Jeddah-Live$Sales Header].[Sell-to Customer No_] = dbo.[Jeddah-Live$Sales Line].[Sell-to Customer No_]  

WHERE DATEDIFF(d,dbo.[Jeddah-Live$Sales Line].[Shipment Date],GETDATE()) = 0

IN C# WINDOWS FORM VISUAL STUDIO 2008 IN TIMER TICK EVENT INTERVAL IS 1000MILISECOND(EVERY SECOND)

ales.SalesClass SalesClass1 = new Sales.SalesClass();

DataTable dt = SalesClass1.ShowSalesData("Data Source=192.168.1.5;Initial Catalog=Altawi-last06-01-2015;User ID=admin;Password=123");

dataGridView1.DataSource = dt;

dataGridView1[0, dataGridView1.Rows.Count - 1].Value = "Total Sum";

dataGridView1.Rows[dataGridView1.Rows.Count - 1].Cells[0].Style.BackColor = Color.Yellow;

dataGridView1.Rows[dataGridView1.Rows.Count - 1].Cells[1].Style.ForeColor = Color.Red;
