Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problembeschreibung: | |
Incorrect results are possible when doing nested math operations on columns that are defined with NOT NULL and using functions. Example (pseudo-code): create function3(col1 bigint,col2 bigint) { return function1(col1)-function2(col2); } SELECT SUM(function3(column1,column2)) from table; <-- intermittent incorrect results are possible on databases with smaller non-automatic SORTHEAP. | |
