Oracle 11g 按用户分组计算不同的产品

Question

I have a table with following fields

ID	PRODUCT	STATUS	USERID	Date
1	100	1	10	01-01-2023
2	101	1	10	01-01-2023
2	102	2	10	01-01-2023
3	100	2	20	02-01-2023
4	102	1	30	02-01-2023
4	100	1	10	03-01-2023

Desired output

Distinct product scan by each userid between 01-01-2023 to 03-01-2023 and count by status for each user

USERID	PRODUCT SCAN	STATUS1 CNT	STATUS2 CNT
10	3	2	1
20	1	0	1
30	1	1	0

Answer 1

Use COUNT(DISTINCT column_name) .

Query

select userid, count(distinct product) as productScan
from table_name
where date between '2023-01-01' and '2023-01-03'
group by userid;
