Does Oracle SQL Have a Built-in Product Function for Multiplying Column Values?

Is There an Oracle SQL Function for Product Calculation?

While Oracle SQL features a SUM function for aggregating numerical values, a PRODUCT function equivalent remains elusive. For those seeking to multiply values analogous to the SUM operation, a workaround is available.

By utilizing the natural logarithm (LN) and exponential (EXP) functions, you can simulate the PRODUCT operation:

SELECT EXP(SUM(LN(col)))
FROM table;

This query effectively calculates the product of values in the 'col' column. For example, given the table:

X

3

5

2

The query would yield:

EXP(SUM(LN(3) + LN(5) + LN(2)))
= EXP(LN(3 * 5 * 2))
= 30

Note that this workaround assumes that the values in 'col' are always positive. If negative values exist, the query must be modified accordingly.
