Cannot use NEXT_DAY function in Fusion BI Publisher Data model

Summary

Cannot use NEXT_DAY function in Fusion BI Publisher Data model

Content

Hi All,

I am trying to run the below query to get the next Saturday in a BI Publisher Data model.

SELECT TRUNC (NEXT_DAY (TRUNC (SYSDATE, 'IW'), 'SATURDAY')) FROM DUAL

However it keeps giving me the below error.

oracle.xdo.servlet.data.DataException: oracle.xdo.XDOException: java.sql.SQLDataException: ORA-01846: not a valid day of the week

Is there a technical limitation here? The query in question works perfectly when I run it in SQL Developer.

How do I calculate the next SATURDAY from today in BI Publisher.

Regards,

Abhradeep

Try this

SELECT NEXT_DAY( TRUNC(to_date('21-MAY-2025'), 'MM') - 1 , 'Sunday' ) FROM dual

And depending on your version of the DB you no longer need the 'FROM dual' 😀

Try Below query:

SELECT
NEXT_DAY(TRUNC(SYSDATE, 'MM') - 1, 'SUNDAY') AS First_Sunday,
NEXT_DAY(TRUNC(SYSDATE, 'MM') - 1, 'SUNDAY') + 7 AS Next_Sunday
FROM dual;

SELECT NEXT_DAY(TRUNC(SYSDATE, 'MM') - 1, 'SUNDAY') AS First_Sunday
FROM dual;
