Re: select on set yields exponential notation
Ah, I see. Of course. And adding 0 is exactly what the manual says to do. I was about to reply to say that |0 works where +0 does not when Bernard sent his excellent suggestion to cast as unsigned. Then I spent a while trying to figure out why you got such a large number for '40'. I finally noticed you had '30' twice, '40' where one would expect '50', and no '50' in the set definition, so '40' is the 49th element of the set. I don't expect that's a problem for you, as I imagine you just made up that table to illustrate the issue, but it boggled my mind for a bit. Now, it seems to me, the question is whether this is a bug or a documentation error.

Re: select on set yields exponential notation
If you are using 4.0.2 and above you can use cast. mysql select var1,cast(var2 as unsigned) from test1; +--++ | var1 | cast(var2 as unsigned) | +--++ |1 |562949953421312 | |1 | 1 | |1 | 32768 | +--++ 3 rows in set (0.00 sec) Note I add a row with 1 and another with 16.
