Feasibility of entity framework and linq to sql -

-

Do you have to spend time in these frameworks? Or they have developed another framework such as Microsoft's MFC Library. I do not want to waste precious time, so please help which scenario would be useful under these scenarios.

are EF and L2S. Wherever one ORM is used, they will be used. Stack overflow Linq uses its ORM layer as SQL, for good effect. The unit framework is up-and-coming, and although there are currently problems, this will improve greatly in the upcoming version 4.0.

Your time will be good to learn one or both of these frameworks, because it will be very likely that you will use an ORM at some point in your applications.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
