I am trying to produce a list of branches that haven't made any sales in the last 3 years. I have been able to produce a list of sales that are older than 3 years but not with the added condition of 0 sales in the 3 years prior.
My task is as follows: List all of the branches that have not rented out any tools for more than 3 years.
I think that I have to do a nested subquery but I cannot work out what should go where. Here are the two relevant tables with their descriptions and data values. The only value that should be returned is that for branch 70.

Now, running the following query returns the orders that are 3 years old. I need to adjust it (I think) using a nested subqueries, so that it checks there are no sales in the 3 years, but cannot work out how.
SQL> select count(toolorder.orderid) as rentalcount, branch.branchid, branch.bname,
branch.address from toolorder left outer join branch on toolorder.branchid =
branch.branchid where MONTHS_BETWEEN(sysdate, dateout) > 36 group by branch.branchid,
branch.bname, branch.address order by 1 desc;
RENTALCOUNT BRANCH BNAME ADDRESS

The easiest way to do this is to get the maximum dateout for each branchid and check that it is more than 36 months in the bast:
select b.*
from branch b join
(select branchid, max(dateout) as maxd
from toolorder
group by branchid
) tob
on b.branchid = tob.branchid
where MONTHS_BETWEEN(sysdate, tob.maxd) > 36;
You can use NOT EXISTS to check if something does not match in a correlated sub-query:
SELECT *
FROM branch b
WHERE NOT EXISTS ( SELECT 1
FROM toolorder r
WHERE r.branchid = b.branchid
AND MONTHS_BETWEEN(sysdate, dateout) <= 36 );
From your comment on #Gordon Linoff's answer, it looks like you want to delete matching rows; in which case you can do:
DELETE FROM branch b
WHERE NOT EXISTS ( SELECT 1
FROM toolorder r
WHERE r.branchid = b.branchid
AND MONTHS_BETWEEN(sysdate, dateout) <= 36 );

Let's say I have three tables:
Employees:

---------- -------------------- ----------
10234 Able 8
11567 Baker 9
3289 George 10
88331 Alice 11
Employee_made:

Sandwich:
SID PRICE NAME
---------- ---------- ------------------------------
12 2 hamburger on wheat
13 2 cheese burger
21 1.75 fish burger on rye
23 1.75 fish burger on wheat
31 3 veggie burger on wheat
11 2 hamburger on rye
I need to list all the employees who have made ALL the different sandwiches, and display their names and PID. What I've gotten so far is:
Select E.name, E.pid
From employees E, employee_made EM, sandwich S
Where E.pid = EM.pid
Which tells me the matching PIDs from the employees and employee_made table. Where I'm not sure to go is how to display the employees who have made ALL the sandwiches, so matching not any SID to the employee_made table, but ALL of them.
First, never use commas in the FROM clause. Always use proper, explicit JOIN syntax.
You can approach this by counting the number of sandwiches mades by employees and then comparing to the total count of sandwiches:
select em.pid
from employee_made em
group by em.pid
having count(distinct em.sid) = (select count(*) from sandwich);
This gives the pid of the employee. I'll let you figure out how to bring in the employee name (hint: in, exists, and join could all be used).
I have two tables
customers_bought:
PID SID QUANTITY
---------- ---------- ----------
3289 11 12

88331 31 48
customers:

3289 George
88331 Alice
74591 Jane
10234 Able
What I need to be able to do is list the customers who bought the greatest number of sandwiches of a single type. I also need to display the customer name, pid, sid, and quantity. This being SQL, of course it's more complicated than it sounds. I'm unsure how to join the two results I have below, here's what I have managed to do:
Code:
Select C.pid, C.name, CB.sid, CB.quantity
From customers C
Inner Join customers_bought CB
On CB.PID = C.PID;
Result:
PID NAME SID QUANTITY
---------- -------------------- ---------- ----------
3289 George 11 12
74591 Jane 11 10
74591 Jane 12 1
74591 Jane 23 1
74591 Jane 31 1
88331 Alice 13 21
88331 Alice 31 48
Code:
Select CB.sid, MAX(CB.Quantity)
From customers_bought CB
Group By CB.sid
Result:
SID MAX(CB.QUANTITY)
---------- ---------------------------------------
11 12
13 21
31 48
23 1
12 1
Try this one
Select
C.pid, C.name, CB.sid, ms.MaxQuentity
From customers C
Inner Join customers_bought CB
On CB.PID = C.PID
INNER JOIN
(
Select
CB.sid,
MAX(CB.Quantity) AS MaxQuentity
From customers_bought CB
Group By CB.sid
) ms ON ms.sid = CB.sid AND ms.MaxQuentity = CB.QUANTITY

How can I obtain this result? (That displays the profitability of each of the salespeople ordered from the most profitable to the least. Gross is simply the sum of the quantity of items sold multiplied by the price. Commission is calculated from the gross minus the cost of those items (i.e. from
qty*(price-cost)). Net profit is the total profit minus commission.)

My attempt:
CREATE PROC Profitability AS
SELECT
sp.EmployeeName, (sum(s.Qty) * a.Price) as [Gross],
[Gross] - a.Cost, as [Commision],
SOMETHING as [Net Profit]
FROM
Salespeople sp, Appliances a, Sales s
WHERE
s.AppID = a.ID
AND sp.EmployeeID = s.EmployeeID
GROUP BY
sp.EmployeeName
GO
EXEC Profitability
Simple rule: Never use commas in the FROM clause. Always use explicit JOIN syntax.
In addition to fixing the JOIN syntax, your query needs a few other enhancements for the aggregation functions:
SELECT sp.EmployeeName, sum(s.Qty * a.Price) as Gross,
SUM(s.Qty * (a.Price - a.Cost)) * sp.CommRate / 100.0 as Commission,
SUM(s.Qty * (a.Price - a.Cost)) * (1 - sp.CommRate / 100.0) as NetProfit
FROM Sales s JOIN
Salespeople sp
ON sp.EmployeeID = s.EmployeeID JOIN
Appliances a
ON s.AppID = a.ID
GROUP BY sp.EmployeeName sp.CommRate
ORDER BY NetProfit DESC;
In my DB there are three tables. I am trying to figure out how to List the school name, class name and teacher's name. Sort the records by class name within school name. I have a query but it is not working. How can I list the school name, class name and teacher's name and sort record by class name within school name?
SELECT c.class_name FROM class c INNER JOIN teacher t WHERE t.teacher_id = c.teacher_id INNER JOIN school s WHERE t.school_id = s.school_id;

You can use the join to get what you want. This will give the all schools with the teachers and there classes.
SELECT DISTINCT

teach.LAST_NAME ,

school sc JOIN teacher teach
ON sc.SCHOOL_ID = teach.SCHOOL_ID
JOIN class cs ON cs.TEACHER_ID = teach.TEACHER_ID
ORDER BY

SELECT t.FIRST_NAME +' '+t.LAST_NAME, s.SCHOOL_NAME, c.class_name

I have database table that I am after some SQL for (Which is defeating me so far!)
Imagine there are 192 Athletic Clubs who all take part in 12 Track Meets per season.
So that is 2304 individual performances per season (for example in the 100Metres)
I would like to find the top 48 (unique) individual performances from the table, these 48 athletes are then going to take part in the end of season World Championships.
So imagine the 2 fastest times are both set by "John Smith", but he can only be entered once in the world champs. So i would then look for the next fastest time not set by "John Smith"... so on and so until I have 48 unique athletes..
hope that makes sense.
thanks in advance if anyone can help
PS
I did have a nice screen shot created that would explain it much better. but as a newish user i cannot post images.
I'll try a copy and paste version instead...
