Check if a given year is leap year in PL/SQL
Prerequisite – PL/SQL introduction
In PL/SQL code groups of commands are arranged within a block. A block group related declarations or statements. In declare part, we declare variables and between begin and end part, we perform the operations.
Given a year, the task is to check that given year is a leap year or not.
Examples:
Input: 1500 Output: 1500 is not leap year. Input: 1600 Output: 1600 is a leap year
A year is a leap year if following conditions are satisfied:
1) Year is multiple of 400
2) Year is multiple of 4 and not multiple of 100
-- To check if a -- given year is leap year or not DECLARE year NUMBER := 1600; BEGIN -- true if the year is a multiple -- of 4 and not multiple of 100. -- OR year is multiple of 400. IF MOD( year , 4)=0 AND MOD( year , 100)!=0 OR MOD( year , 400)=0 THEN dbms_output.Put_line( year || ' is a leap year ' ); ELSE dbms_output.Put_line( year || ' is not a leap year.' ); END IF; END ; |
Output:
1600 is a leap year.
