c# - WCF contract for Field level update -

-

I am developing an application that performs some CRUED operations through the WCF service, return method returns the whole unit , Updates are done through legacy system, and only changed values ​​should be updated.

What is the best way to design data contracts for this scenario? The key-value pairs dictionary?

The only thing I can think of is to create our component - that is, a file or In this way, in the database your status continues, on the updates you can compare the previous situation to pass the state. I'm not sure that this is a good way because this key-value will apply more overhead than simply being in pairs.

From outside it may be more CRDD or whatever, but in practical terms, you can be better at passing some signals, as prices have changed.

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'
