DB2 FOR LUW / DB2FORLUW / A50 - DB2

Selecting "<TIME_COLUMN> - <DECIMAL_COLUMN> SECONDS" from a 
column-organized table will produce incorrect results for rows 
where the fractional part of <DECIMAL_COLUMN> is greater than 0 
and less than 0.000000000001.  Similarly, selecting 
"<TIME_COLUMN> + <DECIMAL_COLUMN> SECONDS" from a 
column-organized table will produce incorrect results for rows 
where the fractional part of <DECIMAL_COLUMN> is less than 0 and 
greater than -0.000000000001. 
 
For example, the following SQL statements return a value of 
'11:59:59' when it should return a value of '12:00:00'.  The 
reason it should return a value of '12:00:00' is because SECONDS 
in DB2 should be converted to DECIMAL(27,12) allowing a maximum 
of 12 digits of fractional seconds to be included.  Anything 
smaller should be ignored, but is not being ignored for queries 
against column-organized tables. 
 
create table table1 (t1 time, d2 decimal(20,13)) in ts1 organize 
by column; 
insert into table1 values ('12.00.00',  0.0000000000001); 
select t1 - d2 seconds from table1;
