Recently saw a multi-threaded interview problem, there are three threads to print a, B, C, please use multi-threaded programming, on the screen to cycle the printing of 10 times abcabc ...To see this topic, the first thought is that the solution is to define an integer class object, initialized to 0, shared by 3 threads, if the integer object is equal to 0 after the remainder of 3, then print a, plus 1 operations, if the integer object 3 is equal to 1, then print B, Add 1 at the same time, if th

Cursor gdata (var1 varchar2) is select item_name, item_name_en, code_value from y0411 where item_name = var1 for update of code_value;
