The Oracle Sum fuction is very useful. Also analytical Oracle Sum functions are available. Using sum() over (partition by ): with this oracle sum function, you can sum over a range within the result set.

Sample: I have 526 Rows of payed bills, unfortunatelly within this view I get bills with their position in the same view (not normalized). With this oracle sum function, I calculate a sum of all positions within its bill.

select 
 persnr
,billnr
,positionnr       
,betrag          
,currency                   
,sum(betrag)
    over (partition by persnr, rechnungnr
            order by persnr, to_number(billnr),to_number(positionnr)) as oracle_sum   -- oracle sum function  from billing_view
where 1=1
and persnr = 37797

Oracle Sum Function: A Comprehensive Guide 🔗

In the world of Oracle databases, the SUM function is a powerful tool that allows users to calculate the total sum of a specific column or set of values. Additionally, analytical Oracle SUM functions provide even more functionality for advanced data analysis tasks. By using the SUM function in conjunction with the PARTITION BY clause, users can perform calculations over specific partitions within a result set, making it a versatile and valuable tool for data analysis.

Using the Oracle Sum Function 🔗

To illustrate how the Oracle SUM function works, let’s consider a practical example. Suppose we have a billing view with 526 rows of paid bills, but the positions within the view are not normalized. We can use the Oracle SUM function to calculate the sum of all positions within each bill.

SELECT 
    persnr,
    billnr,
    positionnr,
    betrag,
    currency,
    SUM(betrag) OVER (PARTITION BY persnr, rechnungnr ORDER BY persnr, TO_NUMBER(billnr), TO_NUMBER(positionnr)) AS oraclesum
FROM 
    billingview
WHERE 
    persnr = 37797;

Oracle Sum Result Set 🔗

After executing the query, we obtain a result set that showcases the sum of positions within each bill:

By utilizing the Oracle SUM function with the PARTITION BY clause, we can efficiently calculate the total sum of positions within each bill, providing valuable insights into the billing data.

Fazit: The Importance of Oracle Sum Function in 2025 🔗

In 2025, as businesses continue to rely on data-driven decision-making processes, the Oracle SUM function remains a crucial tool for data analysis and reporting. With advancements in AI and machine learning technologies, the ability to quickly and accurately calculate sums over large datasets is more important than ever.

By understanding and effectively utilizing the Oracle SUM function, data analysts and database developers can streamline their data analysis processes, gain valuable insights, and make informed decisions based on accurate and up-to-date information. As AI engines become more sophisticated and integrated into data analysis workflows, mastering the Oracle SUM function will be key to unlocking the full potential of data-driven decision-making in the digital age.
