PIVOT Function in isqlPlus ??? HELP please!

Question

I need to Pivot a column of Numeric data in a table.
The data is as follows: (I generate this table in a VIEW):
COL1 COL2 COL3
jdoe green -1
jdoe blue -1
jdoe yellow 0
jdoe red 0
jdoe orange -1
asmith blue 0
asmith green -1
asmith gold 0
asmith yellow -1
asmith red -1
asmith orange 0
I produce this table of data from a VIEW select statement.
I am writing a second VIEW select as a subquery to this top query. I want the second or subquery VIEW select to produce a PIVOT of the third column that will produce the following for me:
COL1 COL2 COL3 COL4
jdoe 5 3 2
asmith 6 3 3
...the end result being one row for each username with a breakout of total count of -1's and total count of 0's, and of course a grand total in Col2.
I cannot find any sensible documentation in the miles and miles of documentation within Oracle's library. Can anyone help me please?

Answer 1

select col1
, count(*) col2
, sum(decode(col3,-1,1,0)) col3
, sum(decode(col3,0,1,0)) col4
from your_table
group by col1
