Question : 为什么我们将差异除以 100 以获得以秒为单位的时间？

Start
Get current time(Start Time)
Perform logical transaction
Get current time(End Time)
Subtract End Time – Start Time
Divide it by 100 to get total time in seconds. (Why 100?)
Stop

试试下面的代码：

declare START_TIME PLS_INTEGER;
begin

    START_TIME := DBMS_UTILITY.GET_TIME;
    DBMS_OUTPUT.PUT_LINE('START_TIME-->'|| START_TIME);

    dbms_lock.sleep(10);
    DBMS_OUTPUT.PUT_LINE('DBMS_UTILITY.GET_TIME-->'|| DBMS_UTILITY.GET_TIME);
    DBMS_OUTPUT.PUT_LINE('execution time --> ' || (dbms_utility.get_time - start_time)/100);
end;
