Minutes and hours query problem

Question

I've got the following query in my app:
SELECT NAME,
SUM(HOURS)+SUM(MINUTES/60)-SUBSTR(TO_CHAR((SUM(MINUTES/60)),'9999D00'),6,3) AS"HOURS",
MOD(SUM(MINUTES),60) AS"MINUTES",
SUM(OVERTIME_HOURS)+SUM((OVERTIME_MINUTES/60))-SUBSTR(TO_CHAR(SUM((OVERTIME_MINUTES/60)),'9999D00'),6,3) AS"OT HOURS",
MOD(SUM(OVERTIME_MINUTES),60) AS"OT MINUTES",
SUM (STAT) AS "STAT",
SUM(HOURS + (MINUTES/60) + (OVERTIME_HOURS*1.5) + ((OVERTIME_MINUTES/60)*1.5) + STAT)-SUBSTR(TO_CHAR(SUM((MINUTES/60)+((OVERTIME_MINUTES/60)*1.5)),'9999D00'),6,3) AS "TOTAL HOURS",
MOD(SUM(MINUTES+(OVERTIME_MINUTES*1.5)),60) AS"TOTAL MINUTES"
FROM KTT_INFORMATION
WHERE DAY BETWEEN (:P15_FROM_DATE) AND (:P15_TO_DATE)
GROUP BY NAME
I want the hours and minutes to display as hours in one column and the remaining minutes in the next column. The minutes are only 15,30 or 45 in the table. For some reason one of the hours columns is giving an output with a decimal. Where the output should be 191 hours and 45 minutes I'm getting 191.5 hours and 15 minutes.
Any ideas?

Answer 1

create or replace function get_time(p_time number)
return varchar2
is
v_time varchar2(20);
begin
v_time:=to_char(trunc(mod(p_time,3600)/60), 'FM00') || ':' || to_char(mod(p_time,60), 'FM00');
return (v_time);
exception
when others then
return null;
end get_time;
show errors;
i created a function which converts given minutes into hrs and min.
then i created a tem table and trying to insert hrs into one column and min into anothere column.
CREATE TABLE TEMP
TIME NUMBER(3) NOT NULL,
HRS NUMBER(3) NOT NULL,
MIN NUMBER(3) NOT NULL
insert into temp values (150,substr(get_time(150),1,2) ,substr(get_time(150),4,5))
hope this may be helpful to you.
