How can I multiply numbers(data) in one column in MySQL?

Question

How can I multiply all numbers in one column?

for example:

Status(finished or not finished)
            1
            1
            1
            1
            0

I know how to use sum.

sum(Status)=4

I need some thing like sum for multiply

mul(status)=0

do we have something like mul(status)?

I don't know of a multiply aggregate function. However, in the case of a column containing only zeroes and ones the product will be one only if every value be one, otherwise it will be zero:

SELECT
    CASE WHEN SUM(status) = COUNT(status) THEN 1 ELSE 0 END AS product
FROM yourTable
