PRODUCT
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The PRODUCT()
aggregate function is an aggregate function that calculates the product of all values in the group, similar to how the SUM function calculates the sum.
SELECT product(ID) FROM BOOK
create.select(product(BOOK.ID)) .from(BOOK)
Producing:
+---------+ | product | +---------+ | 24 | +---------+
Dialect support
This example using jOOQ:
product(BOOK.ID)
Translates to the following dialect specific expressions:
Access
(SWITCH(sum( SWITCH(BOOK.ID = 0, 1) ) > 0, 0, (sum( SWITCH(BOOK.ID < 0, -1) ) MOD 2) < 0, -1, TRUE, 1) * exp(sum(log(abs(iif(BOOK.ID = 0, NULL, BOOK.ID))))))
ASE
(CASE WHEN sum( CASE BOOK.ID WHEN 0 THEN 1 END ) > 0 THEN 0 WHEN (sum( CASE WHEN BOOK.ID < 0 THEN -1 END ) % 2) < 0 THEN -1 ELSE 1 END * exp(sum(log(abs(nullif(BOOK.ID, 0))))))
