问题 I was asked this question during an interview for a Junior Oracle Developer position, the interviewer admitted it was a tough one: Write a query/queries to check if the table 'employees_hist' is an exact copy of the table 'employees'. Any ideas how to go about this? EDIT: Consider that tables can have duplicate records so a simple MINUS will not work in this case. EXAMPLE EMPLOYEES NAME -------- Jack Crack Jack Crack Jill Hill These two would not be identical. EMPLOYEES_HIST NAME --------

问题 I have two sound files, and one is simply an excerpt from the larger file, and should be nearly identical for that part How might I compare the two sound files so as to find out how far into the larger one the smaller one starts playing? This would preferably be a linux terminal command, for use with bash 回答1: If they are .WAV files and one was created directly from the other, then there should be a section which is byte for byte identical, and a good diff tool can find it for you. If they

Consider this code: static int x2 = 10; public static void Main() { short y = 10; Console.WriteLine(y.Equals(x2)); //False Console.Read(); } Why y.Equals(x2) returns false ? 回答1: Int16.Equals specific docs Return Value true if obj is an instance of Int16 and equals the value of this instance; otherwise, false.

问题 I've been working with web-forms and I want to switch to the MVC pattern based on some facts and other goodies that I see in it. I was going good with MVC review when I came across the latest Dynamic Data (which in past was called Dynamic Data Templates).

We can make a running website with-in a few
