Issue in a query

Question

Gurus,
I have a table A
like
col1 col2 count
a p1 0 ---> (IF count >=1 for col1 ,regardless of we have multiple values ,we should count that as 1)
a p2 1
b p3 0 ----> return 0
c p4 1 ----> return 1
e p5 9 ----> return 1
I need to query the table and insert display as
x --> sum(1)
y -- > sum(0)
I have been trying but no luck.
Please help me.
Thanks

Hi,
Is this what you want?
SELECT       COUNT (CASE WHEN SUM (col3) = 0 THEN 1 END)     AS x
,       COUNT (CASE WHEN SUM (col3) > 0 THEN 1 END)     AS y
FROM       a
GROUP BY  col1
;COUNT is not a good column name. I called the 3rd column of your table col3 instead of COUNT.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
If you're asking about a DML statement, such as INSERT, the sample data will be the contents of the table(s) before the DML, and the results will be state of the changed table(s) when everything is finished.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using.

You'll get better answers faster if you always supply this information whenever you post a question.
