Creating a Parameterized Function with System Date Default in Oracle In this article, we will explore how to create a parameterized function in Oracle that meets the requirements. We’ll delve into the details of creating a pipelined function, handling default parameters, and using the NVL function to replace NULL values. Introduction to Pipelined Functions in Oracle Pipelined functions are a type of stored procedure in Oracle that allows you to process data in a streaming fashion.

The issue with your query is that you are grouping by multiple columns (m.eid, m.cid, m.id) along with p.pDate, p.pFreq and p.PHrs. This is causing duplicate rows in the result set because SQL does not enforce uniqueness on these columns. To fix this, ensure that the GROUP BY clause matches the SELECT clause to have distinct summary rows (excluding aggregation functions such as SUM()). In this case, I commented out m.
