Product of an entire Collumn MySQL Does MySQL have any functions like SUM but then do the MULTIPLICATION of a collumn?

Example:
I have an table like this, and I want to multiply the entire collumn

+--------------+
| combinations |
+--------------+
|            3 |
|            5 |
|            4 |
|            6 |
|            1 |
|            3 |
|            4 |
+--------------+


expected result:

+----------------------------+
| product_total_combinations |
+----------------------------+
|                       4320 |
+----------------------------+


I cannnot find anywhere how to achieve this. Any help is appreciated.
As explained by How do I create a user-defined aggregate function? there is no such aggregate function (also see here).

However you can emulate your product by:

log(product(x) ) = sum(log(x))

SELECT EXP(SUM(LOG(a))) AS product
FROM t ;


Beware, there could be rounding errors. If this is all integers, do ROUND(...) around the EXP.
