Here we will see how to check given year is leap year or not, using PL/SQL. In PL/SQL code, some group of commands are arranged within a block of related declaration of statements.
The leap year checking algorithm is like below.
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;
2012 is leap year
