The following problem occur using the sum() function (see the attached
file for all the details and an example):
- if you use it on a portion of a table (example: table age) you get a
result that differ from the one you can get by hand (see the whole table
temp1 and do the sum by hand)
- if you use the sum() function on the complete table (i.e. if you
first create a temporary table and then run the sum() function) then you
get the right result (see example on temp1).
Conclusion: I am not sure its really a bug but this differences can be
really misleading.
Have a nice day,
