10 + 100), whereas his salary is only $1,350 In the preceding example, both updates were changing the same column The problem can occur even if different columns of the same row are being updated by two different transactions This happens when the application performing updates is written such that instead of updating only the changed columns of a record (it takes more work to detect which column changed), all (nonprimary key) columns are updated For example, let s consider an application screen that allows the end user to update the salary and commission of an employee in our emp table Adam, in session 1, is updating the comm column of the emp table for Martin s record In a different session, Blake is changing the sal column of the same record.

ID of the UpdatePanel control that the UpdateProgress control displays the status for. The value in milliseconds before the UpdateProgress control is displayed. A value that determines whether the progress template is rendered dynamically. If set to false, it will take up the required space at all times even if the progress content is not displayed.

The application performing the update doesn t detect which column changed, so it happily updates all (nonprimary key) columns that are updateable from the screen (in this case, the sal and comm columns), resulting in a lost update First, Blake queries Martin s record: blake@ORA10G> select ename, sal, comm from emp where ename='MARTIN'; ENAME SAL COMM ---------- ---------- ---------MARTIN 1350 1400.

Next, Adam queries Martin s record: adam@ORA10G> select ename, sal, comm from emp where ename='MARTIN'; ENAME SAL COMM ---------- ---------- ---------MARTIN 1350 1400 Blake issues an update of the sal column, but the application doesn t detect whether the sal or comm column changed. It updates the sal column to the new value and refreshes the comm column to the old value: blake@ORA10G> update emp set sal = sal*1.10, comm=1400 where ename='MARTIN'; 1 row updated. blake@ORA10G> select ename, sal, comm from emp where ename='MARTIN'; ENAME SAL COMM ---------- ---------- ---------MARTIN 1485 1400 blake@ORA10G> commit; Commit complete. Meanwhile, another session is issuing an update of the comm column, and this time the sal column is being refreshed to its old value, thus wiping out the update to sal done by Blake in the previous session: adam@ORA10G> update emp set comm = comm * 1.10, sal=1350 where ename='MARTIN'; 1 row updated. adam@ORA10G> select ename, sal, comm from emp where ename='MARTIN'; ENAME SAL COMM ---------- ---------- ---------MARTIN 1350 1540 adam@ORA10G> commit; Commit complete.

In many large web applications today, long running data operations are not uncommon. In such cases, it s helpful to use the UpdateProgress control to notify the user about the running status of the application. For the sake of simplicity, let s create a page that simulates a long running process by pausing the running thread for a few seconds. To build this page, drop new ScriptManager, UpdatePanel, and UpdateProgress controls on a new WebForm page. After that, create a new Button control in the UpdatePanel. In the source view of the .aspx page, create a new <ProgressTemplate> tag within the UpdateProgress tag with the following markup:

We ll look at the following three techniques for dealing with lost updates in detail in the following sections: Setting the transaction isolation level to SERIALIZABLE: When we set the transaction to SERIALIZABLE, we get an error if we issue an update on data that has changed since our transaction began. This can prevent lost updates in some scenarios, as we will discuss shortly. Using pessimistic locking: This technique involves explicitly locking the row that needs to be updated in advance to prevent lost updates. Using optimistic locking: This technique involves a mechanism to detect that the row the user is updating has changed, in which case the user typically has to retry her operation.

query. For example, even if a row has been deleted from the database, if it existed in the result set originally, its value would be retained within the cached result set. This reduces the utility of the refreshRow() operation.
