When it comes to handling date and time, Oracle PL/SQL is not as easy or convenient as Microsoft SQL. For instance, with MS SQL, you can write a query like: SELECT * FROM SomeTable WHERE DateAdded = ’09-29-2006 08:00:00 AM’ But with PL/SQL, the above query will not run and will generate an error message like ‘not a valid month’. To make it work, you have to use “To_Date” function to convert the DateTime string […]

An exception ‘System.ExecutionEngineException’ has occurred in DefaultDomain.” And then I got a choice of […]
Sometimes, we need to run the event handler of a server control before executing some javascript code. For instance, when user clicks a button called “Save and Close Window”, the application saves data into database, then closes the window automatically. How can we accomplish this? We can’t add an “onclick” javascript to the button’s attributes, because if we do, then the application will run the javascript code and thus close the window before it even […]
