How to Get Age In Years,Months And Days Using Oracle?

8 minutes read

To get age in years, months, and days using Oracle, you can use a combination of functions to calculate the difference between the birthdate and the current date. You can use the MONTHS_BETWEEN function to get the difference in months, and then use the TRUNC function to get the integer value of that difference.


Next, you can use the EXTRACT function to extract the year and month values from the remaining difference. Finally, you can calculate the number of days by subtracting the calculated years and months from the original difference in months, and use the EXTRACT function again to get the remaining days.


By combining these functions, you can accurately calculate the age in years, months, and days using Oracle.

SELECT 
    FLOOR(MONTHS_BETWEEN(SYSDATE, birth_date) / 12) as age_years,
    MOD(MONTHS_BETWEEN(SYSDATE, birth_date), 12) as age_months,
    (SYSDATE - ADD_MONTHS(birth_date, FLOOR(MONTHS_BETWEEN(SYSDATE, birth_date)))) as age_days
FROM 
    your_table_name


In this query, replace birth_date with the date of birth column in your table and your_table_name with the actual name of the table. This query will calculate the age of each person in the table in years, months, and days.

    v_days NUMBER;
BEGIN
    SELECT FLOOR(MONTHS_BETWEEN(SYSDATE, birth_date)) INTO v_months FROM DUAL;
    v_weeks := ROUND((SYSDATE - ADD_MONTHS(birth_date, v_months)) / 7);
    v_days := MOD((SYSDATE - ADD_MONTHS(birth_date, v_months)), 7);

    RETURN v_months || ' months, ' || v_weeks || ' weeks, ' || v_days || ' days';
END;
/

-- Example of using the function
SELECT calculate_age(TO_DATE('1990-01-01', 'YYYY-MM-DD')) AS age FROM DUAL;
