First of all, thanks in advance for any help anyone can offer!
I'm fairly new to Oracle, so I apologize if this question is stupid...
I'm having an issue getting a query to run properly, and the issue is with the GROUP BY clause in the query.
When running the query, I get the error stating that it's not a GROUP BY statement?? Not really sure what that means.
Here is the query:

NEW ANSWER BASED ON COMMENT
Sorry I should have looked a bit closer I read the statement 'I get the error stating that it's not a GROUP BY statement' saw the count and made an assumption with my original answer.
With the further information provided in the comments I think the issue is actually that you are using the column alias in the group by.
When grouping you actually have to use the field names not the alias, if you have a static value (in this case '' AS MEMBERSXXXXL) you do not need to group by it SO
incorrect select using alias in the group by
select column1, column2 || column 3 as test2, '' as test, count(1) as cnt
from table
group by column1, test2, test
correct select omitting static value and putting full field in the group by
select column1, column2 || column 3 as test2, '' as test, count(1) as cnt
from table
group by column1, column2 || column 3
ORIGINAL ANSWER BELOW
where you have a count, min, max, sum ect within your select statement you need to tell it how to group the other columns....
you have
COUNT(invl.INVOICE_LINE_KEY) AS CONTRACTSXXXXL,
This means you will need a group by clause on your select.
Good resource for basics of this is
https://www.oracletutorial.com/oracle-basics/oracle-group-by/
select col_1,
col_2
from tbl_a A,
tbl_b B,
( select col_1,col_2 from tbl_c where clo_c_1 <> '1' ) C
where A.col_1 = B.col_1
and A.col_2 = B.col_2
and (A.col_2 = B.col_2
or C.col_2 = A.col_2);
My environment is Oracle,when I run this SQL,if the sub SQL C hasn't got a result,then the entire SQL returns NULL.Whereas if C has a result(not null) which fits other condions,there could be a result.Would somebody explain why sub SQL at the from area need to be not NULL?Thanks very much.
You need to bring yourself into the 90s and start using standard joins:
select col_1,
col_2
from tbl_a A
inner join
tbl_b B
on A.col_1 = B.col_1
and A.col_2 = B.col_2
left join
( select col_1,col_2 from tbl_c where clo_c_1 <> '1' ) C
on
C.col_2 = A.col_2
As a guess. I'm not entirely sure what your join conditions should be but that's my first attempt.
This is expected behaviour. When you join two result sets, you only want to get results where the join criteria is satisfied. If the criteria are not satisfied, you should get no results.
If I run the query "get me all the employees older than 65, and get their departments", if there are no employees older than 65, you would not expect to get any results, even if there are some departments in the database.
SELECT emp.name, dept.dept_name
FROM emp
JOIN dept
ON (emp.dept_no = dept.dept_no)
WHERE emp.age > 65;
As the others said, if you actually want to get rows regardless of whether the subquery has any results, you need to use an outer join.
I am very new at using Oracle (in the class now). I have a problem with the query I am trying to run. I have researched a lot of other answers on this site and none of them seem to apply directly to my problem so the solutions aren't working.
I need to find the total amount spent on lunches by each employee.
Show first_name, last_name, credit_limit, and total_price_spent in your results.
Order the answer by total_price_spent in descending order. Only show the employees who spent more than their credit limit.
I figured out how to do everything but the part about showing only the employees who spent more than their credit limit. I tried to use a select statement at the end but discovered that I can't use an alias in a select statement so I don't really know where to go from here. Any help would be appreciated. This is what I have so far.
select a.first_name, a.last_name, credit_limit, sum(c.quantity * d.price) as total_price_spent
from l_employees a join l_lunches b on a.employee_id = b.employee_id join l_lunch_items c on b.lunch_id = c.lunch_id join l_foods d on c.supplier_id = d.supplier_id and c.product_code = d.product_code
group by a.first_name, a.last_name, a.credit_limit
order by total_price_spent desc;
As Mike said : Add HAVING
select a.first_name, a.last_name, credit_limit, sum(c.quantity * d.price) as total_price_spent
from l_employees a join l_lunches b on a.employee_id = b.employee_id join l_lunch_items c on b.lunch_id = c.lunch_id join l_foods d on c.supplier_id = d.supplier_id and c.product_code = d.product_code
group by a.first_name, a.last_name, a.credit_limit
having sum(c.quantity * d.price) > credit_limit
order by total_price_spent desc;
I think what you're looking for is a HAVING clause. It's like a WHERE, but is used when you're using group by. You want to drop it in between the group by and order by. Something like 'HAVING total > a.credit_limit' should work. If using the alias 'total' doesn't work (haven't tested this), you might have to do 'sum(c.quantity * d.price)' again in the HAVING clause instead of using total, so HAVING sum(c.quantity * d.price) > a.credit_limit.
select ma.TITLE,ma.ID as aid,ur.USER_ID
from LEO_MENU_ACTIVITY_RELATION mr
inner join LEO_MENU_MASTER mm on mm.ID=mr.MENU_ID
INNER join LEO_MENUACTIVITY ma on mr.ACTIVITY_ID=ma.ID
LEFT OUTER JOIN LEO_USER_RIGHTS ur on ma.ID=ur.MENU_RELATION_ID and ur.MENU_ID=mm.ID and ur.USER_ID='141'
where mm.ID='1'
UNION (SELECT
'List' as TITLE,
1 as ID,
case (WHEN ur.MENU_RELATION_ID=1 THEN NULL ELSE USER_ID END)as USER_ID
from
LEO_USER_RIGHTS)
In the UNION i want perform a conditional select like if ur.MENU_RELATION_ID=1 then the USER_ID should be selected as NULL otherwise the the original value from the 'LEO_USER_RIGHTS' table must be retrieved.
How can i do this ? Please help
Krishnik
If you want to combine in a UNION something based on the first table I think you can only do it by repeating the whole thing like this:
select ma.TITLE,ma.ID as aid,ur.USER_ID
from LEO_MENU_ACTIVITY_RELATION mr
inner join LEO_MENU_MASTER mm on mm.ID=mr.MENU_ID
INNER join LEO_MENUACTIVITY ma on mr.ACTIVITY_ID=ma.ID
LEFT OUTER JOIN LEO_USER_RIGHTS ur on ma.ID=ur.MENU_RELATION_ID and ur.MENU_ID=mm.ID and ur.USER_ID='141'
where mm.ID='1'
UNION (SELECT
'List' as TITLE,
1 as ID,
case (WHEN ur.MENU_RELATION_ID=1 THEN NULL ELSE USER_ID END)as USER_ID
from
LEO_MENU_ACTIVITY_RELATION mr
inner join LEO_MENU_MASTER mm on mm.ID=mr.MENU_ID
INNER join LEO_MENUACTIVITY ma on mr.ACTIVITY_ID=ma.ID
LEFT OUTER JOIN LEO_USER_RIGHTS ur on ma.ID=ur.MENU_RELATION_ID and ur.MENU_ID=mm.ID and ur.USER_ID='141'
where mm.ID='1'
)
If this is used often I would create a view to avoid duplicate code. In ORACLE (I do not know for other SQL dialects) there is a WITH statement enables you to make a sort of "temporary view".
