How to Get Year With Fractional Part From Date In Oracle?

9 minutes read

To get the year with a fractional part from a date in Oracle, you can use the TO_CHAR function along with the format specifier 'YYYY.FF'. This format specifier allows you to display the year with the fractional part of the year in the date.


For example, if you have a date column named "date_column" in a table called "example_table", you can use the following SQL query to get the year with a fractional part from the date:


SELECT TO_CHAR(date_column, 'YYYY.FF') FROM example_table;


This query will return the year with the fractional part of the year from the date_column in the example_table. You can adjust the format specifier as needed to display different formats of the year with a fractional part.

What is the outcome of extracting the year with fractional part from a date in Oracle?

When extracting the year with a fractional part from a date in Oracle, the fractional part will be truncated and will not be displayed. Only the whole number part of the year will be returned.


For example, if you have a date '2022-05-15' and you extract the year with fractional part, you will only get '2022' as the output and the fractional part '0.5' will be discarded.


SELECT EXTRACT(YEAR FROM DATE '2022-05-15') AS YEAR_WITH_FRACTIONAL_PART FROM DUAL;


Output: YEAR_WITH_FRACTIONAL_PART 2022


This is because the YEAR function in Oracle returns an integer data type, which does not include fractional parts.


What impact does the date format have on obtaining the year with fractional part in Oracle?

The date format in Oracle can impact the way the year with a fractional part is obtained. Oracle's default date format does not include fractional parts of a year. However, by using the TO_NUMBER function along with the EXTRACT function, you can extract the year with fractional parts from a date in Oracle.


For example, if you have a date stored as a number in Oracle, you can use the following query to obtain the year with fractional parts:


SELECT TO_NUMBER(EXTRACT(YEAR FROM TO_DATE('01-JAN-2021', 'DD-MON-YYYY')) + (EXTRACT(DAY FROM TO_DATE('01-JAN-2021', 'DD-MON-YYYY'))-1)/365.0) AS YEAR_FRACTIONAL FROM DUAL;


This query will return the year with fractional parts for the given date '01-JAN-2021'. You can adjust the date format and date value as needed to obtain the year with fractional parts for different dates in Oracle.


How to extract year with fractional part from date in Oracle?

To extract the year with a fractional part from a date in Oracle, you can use the following SQL query:

1
2
SELECT EXTRACT(YEAR FROM your_date) + (EXTRACT(MONTH FROM your_date) - 1) / 12
FROM your_table;


In this query:

  • your_date is the date column from which you want to extract the year with a fractional part.
  • your_table is the table containing the date column.


The EXTRACT(YEAR FROM your_date) function extracts the year from the date, while (EXTRACT(MONTH FROM your_date) - 1) / 12 calculates the fraction of the year based on the month. Adding these two values together gives you the year with a fractional part.
