SQL Query Not Working Properly With Multiple Join Clauses - sql

Question

I have been working on this Query for quite a while. I just got a resolution for part of it and now trying to add that query to my big one, I am having some problems with the output of the query.
SELECT T1.[miles],
T2.[name],
T2.[code],
T2.[routesid],
T2.[id],
T2.[company],
T2.[contract],
T2.[supplier],
T3.[tons],
CASE
WHEN T4.miles IS NULL THEN T5.miles
ELSE T4.miles
END MILES2,
CASE
WHEN T4.miles = T1.miles
AND T4.miles != 9999 THEN T4.flatrate
ELSE T5.rate
END AS RATE,
T3.[change]
FROM ((table1 AS T1
JOIN table2 AS T2
ON T1.[company] = T2.[company]
AND T1.[id] = T2.[routesid])
JOIN table3 AS T3
ON T1.[company] = T3.[code])
LEFT JOIN table4 AS T4
ON T1.[company] = T4.[code]
AND ( T1.[miles] = T4.[miles] )
INNER JOIN (SELECT TOP 1 code,
miles,
rate,
flatrate
FROM table4
WHERE miles = 9999
AND active = 1) AS T5
ON T1.[company] = T5.[code]
WHERE T2.[active] = 1
AND T2.[expiration] < '02/10/2015'
AND T1.[miles] > 0
AND T1.[company] = 'COMPANY'
AND T3.[active] = 1;
I know its a big query. I am trying to figure out why it leaves out the numbers that would pair with the miles on table 4 where it pair with 9999. It has no problem printing out these.
MILES NAME CODE ROUTESID ID COMPANY CONTACT SUPPLIER TONS MILES2 CHANGE
140 N/A N/A 3425 185 ILLINI TARIFF 1 N/A 24 140 Weekly
144 N/A N/A 4532 198 ILLINI TARIFF 3 N/A 24 144 Weekly
9999 N/A N/A 2134 150 ILLINI TARIFF 2 N/A 24 9999 Weekly
Its not printing out right now if it matches this case below. Which I got the SQL statement from my previous stack overflow, I got the SQL statement to print if Miles and Miles2 don't match but since I added the SQLs together it stopped working.
MILES NAME CODE ROUTESID ID COMPANY CONTACT SUPPLIER TONS MILES2 CHANGE
140 N/A N/A 3420 170 ILLINI TARIFF 4 N/A 24 9999 Weekly

Here is a demo of the issue
As you can see the 250, 300, 350, 400, 450, and 500 out of TABLE1 isn't displaying.
Here is the resolution

Answer 1

The answer given by Giorgos in your previous Stack Overflow thread worked partially because you only had one company in your example. See this portion of the query?:
INNER JOIN (SELECT TOP 1 code,
miles,
rate,
flatrate
FROM table4
WHERE miles = 9999
AND active = 1) AS T5
ON T1.[company] = T5.[code]
This literally takes only the top row from the table (where miles = 9999 and active = 1) and then tries to join it to the T1 table. Not the top row for each company, just the top row. So whatever company happens to be on the top row is the only one available when you join the T5 table to the T1 table on the company field. You could get around this perhaps by using distinct instead of top 1, if the table doesn't have multiple rows for a single code where miles = 9999 and active = 1 (which I'm guessing you shouldn't, as that would mean there are multiple rates for the same code and miles):
INNER JOIN (SELECT distinct code, miles, rate, flatrate
FROM table4
WHERE miles = 9999 AND active = 1
GROUP BY code) AS T5 ON T1.[company] = T5.[code]
But as others have noted, it is very difficult to understand what you are trying to accomplish, partially because the formatting of your query is odd. And it would help perhaps to re-explain the nature of your tables and the solution you are seeking, as well as defining the problem better.
