Determining the count of columns with a value greater than 0 - tsql

Question

Ok guys/gals...
Here's my result set:
and here's the ultimate results set I want
to achieve the result, I am currently using n (3) subqueries... which is not ideal...
declare #userId int = 436
select
(select count(PRODUCT_ID) from sl_suggested_asset where PRODUCT_ID > 0 and user_id = #userId) As 'PRODUCT_ID',
(select count(DIGI_DOC_ID) from sl_suggested_asset where DIGI_DOC_ID > 0 and user_id = #userId) As 'DIGI_DOC_ID',
(select count(QR_CODE_ID) from sl_suggested_asset where qr_code_id > 0 and user_id = #userId) As 'QR_CODE_ID'
what I would like is to use either a cte or an aggregate...
here's what I was thinking...
select count(product_id), count(DIGI_DOC_ID), count(qr_code_id), user_id
from sl_suggested_asset
where user_id = 436
group by user_id
but this gives me the total number of rows...
so my having clause should be used but that means that I need to have the proper group by predicate... this is where I'm stuck...
here are some examples of what I've tried...
select
count(PRODUCT_ID) As 'PRODUCT_ID'
, count(DIGI_DOC_ID) As 'DIGI_DOC_ID'
, count(QR_CODE_ID) As 'QR_CODE_ID'
, user_id
from sl_suggested_asset
where
PRODUCT_ID > 0
or
DIGI_DOC_ID > 0
or
QR_CODE_ID > 0
and
user_id = 436
group by user_id
and I get...
... here I change the order of the where clause conditions...
select
count(PRODUCT_ID) As 'PRODUCT_ID'
, count(DIGI_DOC_ID) As 'DIGI_DOC_ID'
, count(QR_CODE_ID) As 'QR_CODE_ID'
, user_id
from sl_suggested_asset
where
user_id = 436
and
PRODUCT_ID > 0
or
DIGI_DOC_ID > 0
or
QR_CODE_ID > 0
group by user_id
... and I get the same result as above ...
... now I change the where clause to = 0 and get the same result, which means the where clause is being completely ignored...
select
count(PRODUCT_ID) As 'PRODUCT_ID'
, count(DIGI_DOC_ID) As 'DIGI_DOC_ID'
, count(QR_CODE_ID) As 'QR_CODE_ID'
, user_id
from sl_suggested_asset
where
user_id = 436
and
PRODUCT_ID = 0
or
DIGI_DOC_ID = 0
or
QR_CODE_ID = 0
group by user_id
... lastly, if I change the ors to ands I get zero results ...
select
count(PRODUCT_ID) As 'PRODUCT_ID'
, count(DIGI_DOC_ID) As 'DIGI_DOC_ID'
, count(QR_CODE_ID) As 'QR_CODE_ID'
, user_id
from sl_suggested_asset
where
user_id = 436
and
PRODUCT_ID = 0
and
DIGI_DOC_ID = 0
and
QR_CODE_ID = 0
group by user_id

Answer 1

Just use some CASE STATEMENTS on the Query
SELECT SUM(
CASE
WHEN PRODUCT_ID > 0
THEN 1
ELSE 0
END
) as PRODUCT_ID ,
SUM(
CASE
WHEN DIGI_DOC_ID>0
THEN 1
ELSE 0
END
) as DIGI_DOC_ID,
SUM(
CASE
WHEN QR_CODE_ID>0
THEN 1
ELSE 0
END
) as QR_CODE_ID
FROM sl_SUGGESTED_ASSET
WHERE USER_ID =436
Have a great day!
