在这里,我们将看到如何使用PL / SQL检查给定年份是否为leap年。在PL / SQL代码中,在一组相关的语句声明内安排了一些命令。
year年检查算法如下。
isLeapYear(year): begin if year is divisible by 4 and not divisible by 100, then it is leap year else if the number is divisible by 400, then it is leap year else it is not leap year end
DECLARE year NUMBER := 2012; BEGIN IF MOD(year, 4)=0 AND MOD(year, 100)!=0 OR MOD(year, 400)=0 THEN dbms_output.Put_line(year || ' is leap year '); ELSE dbms_output.Put_line(year || ' is not leap year.'); END IF; END;
输出结果
2012 is leap year
