## All we need is an easy explanation of the problem, so here it is.

This question was born in my mind looking at this kind of code:

```
select sum(value)
into positive
from my_table
where value > 0;
select sum(value)
into negative
from my_table
where value < 0;
```

This works well for take the totals of this table.

But, my question is how I can get the sub-totals of `my_table`

using only a statement.

### expected result:

Having this data on `my_table`

```
VALUE
-----
1.0
-2.0
3.0
-4.0
5.0
-6.7
8.9
```

I’d a DML statement who can give me this output

```
positive | negative
---------+---------
17.9 | -12.7
```

Is this kind of operation possible?

If yes, how can i get it?

### Method 1

```
SQL> r
1 with t as (
2 select 1.0 as x from dual
3 union all select -2.0 as x from dual
4 union all select 3.0 as x from dual
5 union all select -4.0 as x from dual
6 union all select 5.0 as x from dual
7 union all select -6.7 as x from dual
8 union all select 8.9 as x from dual)
9 select sum(case when x > 0 then x else 0 end) as sum_of_positives,
10 sum(case when x < 0 then x else 0 end) as sum_of_negatives
11* from t
SUM_OF_POSITIVES SUM_OF_NEGATIVES
---------------- ----------------
17,9 -12,7
```
