Result in same row instead of two rows

Question

I have to select same field on two different condition ie.
select
(case when data_type_id = 1 then hrscycles else 0 end) totalhours
,(case when data_type_id = 10 then hrscycles else 0 end) totalcycles
from mytable
Problem is query is returning 2 rows whereas i want result in single row.Is there any other solution?

Answer 1

select (case when data_type_id = 1 then hrscycles else 0 end) totalhours,
(case when data_type_id = 10 then hrscycles else 0 end) totalcycles
from mytableyour query in the above will return two columns and will return multiple rows depending on the data your table have.
maybe you want single column?
  select (case when data_type_id = 1 then hrscycles
               else 0
          end) attribute1
    from mytable
  union all
  select (case when data_type_id = 10 then hrscycles
               else 0
          end) attribute1
  from mytableor if you want a multiple rows into a single column:
SQL> select * from pivot_tab;
      COL1 COL2
         1 a
         1 b
         1 c
         2 h
         2 h
SQL> select p.col1,
  2         substr(max(substr(sys_connect_by_path (p.col2,','),2)),1,60)
  3         as col2
  4    from (select col1,
  5                 col2,
  6                 row_number() over (partition by col1 order by col1, col2) rn
  7            from pivot_tab) p
  8  start with p.rn = 1
  9  connect by p.rn = prior p.rn + 1
10  and prior p.col1 = p.col1
11  group by col1;
      COL1 COL2
         1 a,b,c
         2 h,h
