Another example for a deadlock demonstrates the most common cause for deadlocks that I ve stumbled into in production systems lack of sufficient indexes . Processes might end up being in conflict with each other even when they need mutually exclusive resources . This can happen when you re lacking indexes on filtered columns . SQL Server has to scan all rows if there s no index on the filtered columns . Thus a conflict can occur when one process holds a lock on a row while another scans all rows to check whether they qualify to the filter instead of seeking the desired row directly through an index . For example, currently there are no indexes on T1.col1 and T1.col2 . Run the following code in connection 1, which opens a transaction, modifies a row in T1 where col1 = 101, and keeps the transaction open, thus preserving an exclusive lock on the row:

Implement DataSource controls. Implement data-bound controls. Create and configure a Dynamic Data project.

USE tempdb; GO IF OBJECT_ID('dbo.OrderDetails') IS NOT NULL DROP TABLE dbo.OrderDetails; GO CREATE TABLE dbo.OrderDetails ( orderid VARCHAR(10) NOT NULL, productid INT NOT NULL, PRIMARY KEY(orderid, productid) /* other columns */ ); INSERT INTO dbo.OrderDetails(orderid, INSERT INTO dbo.OrderDetails(orderid, INSERT INTO dbo.OrderDetails(orderid, INSERT INTO dbo.OrderDetails(orderid, INSERT INTO dbo.OrderDetails(orderid, INSERT INTO dbo.OrderDetails(orderid, INSERT INTO dbo.OrderDetails(orderid, INSERT INTO dbo.OrderDetails(orderid, INSERT INTO dbo.OrderDetails(orderid, INSERT INTO dbo.OrderDetails(orderid,

You can follow the asynchronous HTTP handler model to create an asynchronous webpage. This is a webpage that works with the IHttpAsynchHandler interface (instead of a registered handler for a specified file extension). For example, assume you were writing the asynchronous HTTP handler in the previous example as a webpage. This webpage would still use the same ImageAsynchOperation class that implements IAsynchResult as defined above. However, it would use this class not in a handler, but on a webpage. The following steps walk you through the basic process of implementing this example inside a standard ASPX page.

will result in the following output:

-- Create table Production.Suppliers_Since IF OBJECT_ID('Production.Suppliers_Since', 'U') IS NOT NULL DROP TABLE Production.Suppliers_Since; CREATE TABLE Production.Suppliers_Since ( supplierid INT NOT NULL, companyname NVARCHAR(40) NOT NULL, since INT NOT NULL CONSTRAINT PK_Suppliers_Since PRIMARY KEY(supplierid) ); -- Create table Production.SuppliersProducts_Since IF OBJECT_ID('Production.SuppliersProducts_Since', 'U') IS NOT NULL DROP TABLE Production.SuppliersProducts_Since; CREATE TABLE Production.SuppliersProducts_Since ( supplierid INT NOT NULL, productid INT NOT NULL, since INT NOT NULL CONSTRAINT PK_SuppliersProducts_Since PRIMARY KEY(supplierid, productid) );

DELETE FROM T1 WHERE keycol = 1;

Now, let s take a closer look at the Program .exe file produced by the C# compiler . What exactly is this file Well, for starters, it is a standard portable executable (PE) file . This means that a machine running 32-bit or 64-bit versions of Windows should be able to load this file and do something with it . Windows supports two types of applications, those with a console user interface (CUI) and those with a graphical user interface (GUI) . Because I specified the /t:exe switch, the C# compiler produced a CUI application . You d use the /t:winexe switch to cause the C# compiler to produce a GUI application .

they should be easy to accommodate by programming in the problem-domain building blocks from the layer below. In addition to these conceptual layers, many programmers find it useful to break a program up into other layers that cut across the layers described here. For example, the typical 3-tier architecture cuts across the levels described here, and provides further tools for making the design and code intellectually manageable.
