insert a random number into each row in table

Question

I currently have an oracle table (lovalarm) containing around 600,000 rows. I need to be able to run a query which will cycle through each row and update a field (lovsiteid

Answer 1

Just not use subquery:

update lovalarm
set lovsiteid = TRUNC(dbms_random.value(14300,17300))

Answer 2

Try this:

update lovalarm set lovsiteid = (select FLOOR(RAND() * (17300 - 14300) + 14300))

works in MySQL
