Creating views in SQL server 2005

After creating tables in SQl server 2005,its time to create views.The Views are reprsentations of parts of the table generated by the datbase based on a usedefined query. These are used primarily to view only required data from a large table.
Expand the database in which the view has to be created and right click on the Views.Select the create new View option and you will be presented with the above screen with the list of tables that are present in the database.We select the emp_table and click on add and then close this window.

After the above window is closed the below window appears. It has four different parts. The top most part contains the list of columns in the emp_table which can be added to the view.The next part provides various options to customise the view. The columns to be included and the alias name that have to be given to those columns in the view, the table in which the column is present, the way the column has to be sorted in the view, the sort order to be followed in the
view, any filters to be used in the view and other options such as the use of aggregate functions etc.

The third part shows the actuall query that is to be run. Once we have choosen the required query either by directly editing the query or using the interface provided, the query can be tested by clciking on the execute button that is highlighted in the above window.The output of the query(either the view or the error message)appears in the fourth part.Once the view of your choice is ready the view can be saved by chossing the save view option under the file menu.

46893711600000 - what does this number signify?

46893711600000 is the number of seconds since "00:00:00 January 1, 1970." that it will take to get unlimited storage space on gmail ...:) If the javascript in the gmail login page is to be belived.

So we will get unlimited storage space in gmail at 01-02-3456 07:00:00 hours.

However, the year 2038 problem if not fixed in future versions of the browsers for Javascript the program will just fail. If you just google for 46893711600000 you will be surprised by the number of results you will get though.
