Re: strange result for select * from table where id=random()*900

hi list,

this is my query:

select 

*

from _g2977 

where 

id=floor(random() * (900));

in table _g2977 i have id(s) from 1 up to 900. i just want to select one random dataset by the above query but i does not work.

actually i get sometime zero, sometimes one, sometimes two and sometimes even three results back from the above query although i thought it should give only one random dataset from the table.

what is wrong?

i appreciate any help.

thanks in advance, stefan
