You might encounter incorrect output from a SQL statement that
satisfies all the following conditions:
1. a DISTINCT clause in the SELECT list;
2. two or more references to table T;
3. if there are k >1 references to table T and a DBPARTITIONNUM
function in the SELECT list on <= k-1 of the references to T
4. A restriction on the set of database partitions in the WHERE
clause (e.g. DBPARTITIONNUM(T.a)=0) on the references to T on
which the DBPARTITIONNUM function in the select list applies |
