Question

In MYSQL db, I need to UPDATE table “people” with a random number between 8 and 120, but if the value is between 103 and 109, I want it to become 110.

How would I do such a query?

UPDATE people SET column1 = '________random expression_________'

Answer 1

I haven’t tested, but perhaps it should work.

UPDATE people 
SET column1 = (
    SELECT if(r.rand BETWEEN 103 AND 109, 110, r.rand)
    FROM ( SELECT floor(8+rand()*113) rand ) r
)
