I have two tables: TaskUser and PaperMaterial
TaskUser - Contains all users One column titled: User1) that could be a user in the PaperMaterial Table
PaperMaterial - Multi-column table where data could be written multiple times for the same user on multiple dates.
What I am trying to accomplish is a query that will show all users for a given date range and their total page count regardless if they have data in the papermaterial table.
IE:
Select Assigned_To,
Case
When PaperMaterial.Assigned_To = TaskUser.User1 then sum(Page_Count)
When PaperMaterial.Assigned_To <> TaskUser.User1 then '0'
End as Count1
From PaperMaterial
Inner Join TaskUser
on TaskUser.User1 = PaperMaterial.Assigned_To
Where Date_Assigned between ('06/09/2014') and ('06/13/2014')
Order By Assigned_To
Now, obviously this code does not work, because I am new to SQL and I am not very good yet. However, you should be able to see the goal here. which is:
Mike 0
Bob 200
Jen 0
Betty 125
so on, so forth
Thank you
I think this will do the trick
SELECT a.User1, ifnull(sum(Page_Count),0) AS Count1
From TaskUser AS a
LEFT JOIN PaperMaterial AS b
ON b.Assigned_To = a.User1
Where Date_Assigned between DATE('2014-06-09') AND DATE('2014-06-13')
GROUP BY a.User1
Order By a.User1
You might need to tweak the Date_Assigned logic, depending on your date formats... but the current clause you're using doesn't really make a lot of sense. I think the one above should do the job, assuming your Date_Assigned variable is formatted as a date or datetime

Consider the following tables:
Table A:
DOC_NUM
DOC_TYPE
RELATED_DOC_NUM
NEXT_STATUS
...
Table B:
DOC_NUM
DOC_TYPE
RELATED_DOC_NUM
NEXT_STATUS
...
The DOC_TYPE and NEXT_STATUS columns have different meanings between the two tables, although a NEXT_STATUS = 999 means "closed" in both. Also, under certain conditions, there will be a record in each table, with a reference to a corresponding entry in the other table (i.e. the RELATED_DOC_NUM columns).
I am trying to create a query that will get data from both tables that meet the following conditions:
A.RELATED_DOC_NUM = B.DOC_NUM
A.DOC_TYPE = "ST"
B.DOC_TYPE = "OT"
A.NEXT_STATUS < 999 OR B.NEXT_STATUS < 999
A.DOC_TYPE = "ST" represents a transfer order to transfer inventory from one plant to another. B.DOC_TYPE = "OT" represents a corresponding receipt of the transferred inventory at the receiving plant.
We want to get records from either table where there is an ST/OT pair where either or both entries are not closed (i.e. NEXT_STATUS < 999).
I am assuming that I need to use a FULL OUTER join to accomplish this. If this is the wrong assumption, please let me know what I should be doing instead.
UPDATE (11/30/2021):
I believe that #Caius Jard is correct in that this does not need to be an outer join. There should always be an ST/OT pair.
With that I have written my query as follows:
SELECT <columns>
FROM A LEFT JOIN B
ON
A.RELATED_DOC_NUM = B.DOC_NUM
WHERE
A.DOC_TYPE IN ('ST') AND
B.DOC_TYPE IN ('OT') AND
(A.NEXT_STATUS < 999 OR B.NEXT_STATUS < 999)
Does this make sense?
UPDATE 2 (11/30/2021):
The reality is that these are DB2 database tables being used by the JD Edwards ERP application. The only way I know of to see the table definitions is by using the web site http://www.jdetables.com/, entering the table ID and hitting return to run the search. It comes back with a ton of information about the table and its columns.
Table A is really F4211 and table B is really F4311.
Right now, I've simplified the query to keep it simple and keep variables to a minimum. This is what I have currently:
SELECT CAST(F4211.SDDOCO AS VARCHAR(8)) AS SO_NUM,
F4211.SDRORN AS RELATED_PO,
F4211.SDDCTO AS SO_DOC_TYPE,
F4211.SDNXTR AS SO_NEXT_STATUS,
CAST(F4311.PDDOCO AS VARCHAR(8)) AS PO_NUM,
F4311.PDRORN AS RELATED_SO,
F4311.PDDCTO AS PO_DOC_TYPE,
F4311.PDNXTR AS PO_NEXT_STATUS
FROM PROD2DTA.F4211 AS F4211
INNER JOIN PROD2DTA.F4311 AS F4311
ON F4211.SDRORN = CAST(F4311.PDDOCO AS VARCHAR(8))
WHERE F4211.SDDCTO IN ( 'ST' )
AND F4311.PDDCTO IN ( 'OT' )
The other part of the story is that I'm using a reporting package that allows you to define "virtual" views of the data. Virtual views allow the report developer to specify the SQL to use. This is the application where I am using the SQL. When I set up the SQL, there is a validation step that must be performed. It will return a limited set of results if the SQL is validated.
When I enter the query above and validate it, it says that there are no results, which makes no sense. I'm guessing the data casting is causing the issue, but not sure.
UPDATE 3 (11/30/2021):
One more twist to the story. The related doc number is not only defined as a string value, but it contains leading zeros. This is true in both tables. The main doc number (in both tables) is defined as a numeric value and therefore has no leading zeros. I have no idea why those who developed JDE would have done this, but that is what is there.
So, there are matching records between the two tables that meet the criteria, but I think I'm getting no results because when I convert the numeric to a string, it does not match, because one value is, say "12345", while the other is "00012345".
Can I pad the numeric -> string value with zeros before doing the equals check?
UPDATE 4 (12/2/2021):
Was able to finally get the query to work by converting the numeric doc num to a left zero padded string.
SELECT <columns>
FROM PROD2DTA.F4211 AS F4211
INNER JOIN PROD2DTA.F4311 AS F4311
ON F4211.SDRORN = RIGHT(CONCAT('00000000', CAST(F4311.PDDOCO AS VARCHAR(8))), 8)
WHERE F4211.SDDCTO IN ( 'ST' )
AND F4311.PDDCTO IN ( 'OT' )
AND ( F4211.SDNXTR < 999
OR F4311.PDNXTR < 999 )
You should write your query as follows:
SELECT <columns>
FROM A INNER JOIN B
ON
A.RELATED_DOC_NUM = B.DOC_NUM
WHERE
A.DOC_TYPE IN ('ST') AND
B.DOC_TYPE IN ('OT') AND
(A.NEXT_STATUS < 999 OR B.NEXT_STATUS < 999)
LEFT join is a type of OUTER join; LEFT JOIN is typically a contraction of LEFT OUTER JOIN). OUTER means "one side might have nulls in every column because there was no match". Most critically, the code as posted in the question (with a LEFT JOIN, but then has WHERE some_column_from_the_right_table = some_value) runs as an INNER join, because any NULLs inserted by the LEFT OUTER process, are then quashed by the WHERE clause
See Update 4 for details of how I resolved the "data conversion or mapping" error.
Hi I have a redshift table of articles that has a field on it that can contain many accounts. So there is a one to many relationship between articles to accounts.
However I want to create a new view where it lists the partner id's in one column and in another column a count of how many times the partner id appears in the articles table.
I've attempted to do this using regex and created a new redshift view, but am getting weird results where it doesn't always build properly. So one day it will say a partner appears 15 times, then the next 17, then the next 15, when the partner id count hasn't actually changed.
Any help would be greatly appreciated.
SELECT partner_id,
COUNT(DISTINCT id)
FROM (SELECT id,
partner_ids,
SPLIT_PART(partner_ids,',',i) partner_id
FROM positron_articles a
LEFT JOIN util.seq_0_to_500 s
ON s.i < regexp_count (partner_ids,',') + 2
OR s.i = 1
WHERE i > 0
AND regexp_count (partner_ids,',') = 0
ORDER BY id)
GROUP BY 1;
Let's start with some of the more obvious things and see if we can start to glean other information.
Next GROUP BY 1 on your outer query needs to be GROUP BY partner_id.
Next you don't need an order by in your INNER query and the database engine will probably do a better job optimizing performance without it so remove ORDER BY id.
If you want your final results to be ordered then add an ORDER BY partner_id or similar clause after your group by of your OUTER query.
It looks like there are also problems with how you are splitting a partnerid from partnerids but I am not positive about that because I need to understand your view and the data it provides to know how that affects your record count for partnerid.
Next your LEFT JOIN statement on the util.seq_0_to_500 I am pretty sure you can drop off the s.i = 1 as the first condition will satisfy that as well because 2 is greater than 1. However your left join really acts more like an inner join because you then exclude any non matches from positron_articles that don't have a s.i > 0.
Oddly then your entire join and inner query gets kind of discarded because you only want articles that have no commas in their partnerids: regexp_count (partner_ids,',') = 0
I would suggest posting the code for your util.seq_0_to_500 and if you have a partner table let use know about that as well because you can probably get your answer a lot easier with that additional table depending on how regexp_count works. I suspect regex_count(partnerids,partnerid) exampleregex_count('12345,678',1234) will return greater than 0 at which point you have no choice but to split the delimited strings into another table before counting or building a new matching function.
If regex_count only matches exact between commas and you have a partner table your query could be as easy as this:
SELECT
p.partner_id
,COUNT(a.id) AS ArticlesAppearedIn
FROM
positron_articles a
LEFT JOIN PARTNERTABLE p
ON regexp_count(a.partnerids,p.partnerid) > 0
GROUP BY
p.partner_id
I will actually correct myself as I just thought of a way to join a partner table without regexp_count. So if you have a partner table this might work for you. If not you will need to split strings. It basically tests to see if the partnerid is the entire partnerids, at the beginning, in the middle, or at the end of partnerids. If one of those is met then the records is returned.
SELECT
p.partner_id
,COUNT(a.id) AS ArticlesAppearedIn
FROM
PARTNERTABLE p
INNER JOIN positron_articles a
ON
(
CASE
WHEN a.partnerids = CAST(p.partnerid AS VARCHAR(100)) THEN 1
WHEN a.partnerids LIKE p.partnerid + ',%' THEN 1
WHEN a.partnerids LIKE '%,' + p.partnerid + ',%' THEN 1
WHEN a.partnerids LIKE '%,' + p.partnerid THEN 1
ELSE 0
END
) = 1
GROUP BY
p.partner_id
I have two mySQL tables that are distantly related: Box and Schedule.
The tables are only related through many other table joins.
A box has a subscription ID, a subscription has a boxContent ID and a boxContent has a Schedule ID.
Many boxes have one subscription
One Subscription has many boxContents
Many boxContents have one Schedule
I need to get all of the Schedule details attached to boxes and group them by the delivery date of the boxes.
The problem I have, is that I cannot figure out how to group them, or join them, so that the subscription and boxcontents data doesnt fill the results up with invalid results.
For example:
SELECT
Box.expected_delivery_date, count(Box.id) num_boxes
FROM
Box
WHERE
Box.state = 3 AND Box.status = 2
GROUP BY Box.expected_delivery_date;
returns the correct amount of boxes that I need to look for:
2010-10-01 - 2
2010-10-07 - 4
However, when I include the tables I need to link the two together, I get all of their data confusing the results
SELECT
Box.expected_delivery_date, count(Box.id) num_boxes
FROM
Box
JOIN
Subscription ON Box.subscription_id = Subscription.id
JOIN
BoxContent ON Subscription.id = BoxContent.subscription_id
JOIN
Schedule ON Schedule.id = BoxContent.schedule_id
WHERE
Box.state = 3 AND Box.status = 2
GROUP BY Box.expected_delivery_date;
Returns:
2010-10-01 - 10
2010-10-07 - 17
Im sure there is a simple way to do this, Im just not great at SQL.
Use DISTINCT to count the distinct Box.id in your query -
SELECT
Box.expected_delivery_date, count(DISTINCT Box.id) num_boxes
FROM
Box
JOIN
Subscription ON Box.subscription_id = Subscription.id
JOIN
BoxContent ON Subscription.id = BoxContent.subscription_id
JOIN
Schedule ON Schedule.id = BoxContent.schedule_id
WHERE
Box.state = 3 AND Box.status = 2
GROUP BY Box.expected_delivery_date;
This should return
2010-10-01 - 2
2010-10-07 - 4
Similarly, when you JOIN box with subscription, content, schedule tables you will get many duplicates. You need to analyze the data and see how you need to GROUP BY.
Use this query to see the actual data used by the query before grouping and decide on which columns to group by. Mostly, it will be the columns where you see duplicate data in multiple rows.
SELECT
Box.expected_delivery_date, Box.id BoxID, Schedule.id SchID
FROM
Box
JOIN
Subscription ON Box.subscription_id = Subscription.id
JOIN
BoxContent ON Subscription.id = BoxContent.subscription_id
JOIN
Schedule ON Schedule.id = BoxContent.schedule_id
WHERE
Box.state = 3 AND Box.status = 2
You may even try SELECT Box.*, Schedule.* in above query to come up with a final grouping.
If you need any more specific answer, you will have to provide the dummy data for all those table and the result you are looking for.
I would agree with the comments and try using DISTINCT. This should filter out the duplicate rows you would be getting by joining your "middle" tables.
My query below is doubling the amount on the last record it returns. I have 3 tables - activities, bookings and tempbookings. The query needs to list the activities and attached information and pull the total number (using the SUM) of places booked (as BookingTotal) from the booking table by each activity and then it needs to calculate the same for tempbookings (as tempPlacesReserved) providing the reservedate field inside that table is in the future.
However the first issue is that if there are no records for an activity in the tempbookings table it does not return any records for that activity at all, to get around this i created dummy records in the past so that it still returns the record, but if I can make it so I don't have to do this I would prefer it!
The main issue I have is that on the final record of the returned results it doubles the booking total and the places reserved which of course makes the whole query useless.
I know that I am doing something wrong I just haven't been able to sort it, I have searched similar issues online but am unable to apply them to my situation correctly.
Any help would be appreciated.
P.S. I'm aware that normally you wouldn't need to fully label all the paths to the databases, tables and fields as I have but for the program I am planning to use it in I have to do it this way.
Code:
SELECT [LeisureActivities].[dbo].[activities].[activityID],
[LeisureActivities].[dbo].[activities].[activityName],
[LeisureActivities].[dbo].[activities].[activityDate],
[LeisureActivities].[dbo].[activities].[activityPlaces],
[LeisureActivities].[dbo].[activities].[activityPrice],
SUM([LeisureActivities].[dbo].[bookings].[bookingPlaces]) AS 'bookingTotal',
SUM (CASE WHEN[LeisureActivities].[dbo].[tempbookings].[tempReserveDate] > GetDate() THEN [LeisureActivities].[dbo].[tempbookings].[tempPlaces] ELSE 0 end) AS 'tempPlacesReserved'
FROM [LeisureActivities].[dbo].[activities],
[LeisureActivities].[dbo].[bookings],
[LeisureActivities].[dbo].[tempbookings]
WHERE ([LeisureActivities].[dbo].[activities].[activityID]=[LeisureActivities].[dbo].[bookings].[activityID]
AND [LeisureActivities].[dbo].[activities].[activityID]=[LeisureActivities].[dbo].[tempbookings].[tempActivityID])
AND [LeisureActivities].[dbo].[activities].[activityDate] > GetDate ()
GROUP BY [LeisureActivities].[dbo].[activities].[activityID],
[LeisureActivities].[dbo].[activities].[activityName],
[LeisureActivities].[dbo].[activities].[activityDate],
[LeisureActivities].[dbo].[activities].[activityPlaces],
[LeisureActivities].[dbo].[activities].[activityPrice];
Your current query is using an INNER JOIN between each of the tables so if the tempBookings table has no records, you will not return anything.
I would advise that you start to use JOIN syntax. You might also need to use subqueries to get the totals.
SELECT a.[activityID],
a.[activityName],
a.[activityDate],
a.[activityPlaces],
a.[activityPrice],
coalesce(b.bookingTotal, 0) bookingTotal,
coalesce(t.tempPlacesReserved, 0) tempPlacesReserved
FROM [LeisureActivities].[dbo].[activities] a
LEFT JOIN
(
select activityID,
SUM([bookingPlaces]) AS bookingTotal
from [LeisureActivities].[dbo].[bookings]
group by activityID
) b
ON a.[activityID]=b.[activityID]
LEFT JOIN
(
select tempActivityID,
SUM(CASE WHEN [tempReserveDate] > GetDate() THEN [tempPlaces] ELSE 0 end) AS tempPlacesReserved
from [LeisureActivities].[dbo].[tempbookings]
group by tempActivityID
) t
ON a.[activityID]=t.[tempActivityID]
WHERE a.[activityDate] > GetDate();
Note: I am using aliases because it is easier to read
Use new SQL-92 Join syntax, and make join to tempBookings an outer join. Also clean up your sql with table aliases. Makes it easier to read. As to why last row has doubled values, I don't know, but on off chance that it is caused by extra dummy records you entered. get rid of them. That problem is fixed by using outer join to tempBookings. The other possibility is that the join conditions you had to the tempBookings table(t.tempActivityID = a.activityID) is insufficient to guarantee that it will match to only one record in activities table... If, for example, it matches to two records in activities, then the rows from Tempbookings would be repeated twice in the output, (causing the sum to be doubled)
SELECT a.activityID, a.activityName, a.activityDate,
a.activityPlaces, a.activityPrice,
SUM(b.bookingPlaces) bookingTotal,
SUM (CASE WHEN t.tempReserveDate > GetDate()
THEN t.tempPlaces ELSE 0 end) tempPlacesReserved
FROM LeisureActivities.dbo.activities a
Join LeisureActivities.dbo.bookings b
On b.activityID = a.activityID
Left Join LeisureActivities.dbo.tempbookings t
On t.tempActivityID = a.activityID
WHERE a.activityDate > GetDate ()
GROUP BY a.activityID, a.activityName,
a.activityDate, a.activityPlaces,
a.activityPrice;
Need help on a query using sql server 2005
I am having two tables
code
chargecode
chargeid
orgid
entry
chargeid
itemNo
rate
I need to list all the chargeids in entry table if it contains multiple entries having different chargeids
which got listed in code table having the same charge code.
data :
code
100,1,100
100,2,100
100,3,100
101,11,100
101,12,100
entry
1,x1,1
1,x2,2
2,x3,2
11,x4,1
11,x5,1
using the above data , it query should list chargeids 1 and 2 and not 11.
I got the way to know how many rows in entry satisfies the criteria, but m failing to get the chargeids
select count (distinct chargeId)
from entry where chargeid in (select chargeid from code where chargecode = (SELECT A.chargecode
from code as A join code as B
ON A.chargecode = B.chargeCode and A.chargetype = B.chargetype and A.orgId = B.orgId AND A.CHARGEID = b.CHARGEid
group by A.chargecode,A.orgid
having count(A.chargecode) > 1)
)
First off: I apologise for my completely inaccurate original answer.
The solution to your problem is a self-join. Self-joins are used when you want to select more than one row from the same table. In our case we want to select two charge IDs that have the same charge code:
SELECT DISTINCT c1.chargeid, c2.chargeid FROM code c1
JOIN code c2 ON c1.chargeid != c2.chargeid AND c1.chargecode = c2.chargecode
JOIN entry e1 ON e1.chargeid = c1.chargeid
JOIN entry e2 ON e2.chargeid = c2.chargeid
WHERE c1.chargeid < c2.chargeid
Explanation of this:
First we pick any two charge IDs from 'code'. The DISTINCT avoids duplicates. We make sure they're two different IDs and that they map to the same chargecode.
Then we join on 'entry' (twice) to make sure they both appear in the entry table.
This approach gives (for your example) the pairs (1,2) and (2,1). So we also insist on an ordering; this cuts to result set down to just (1,2), as you described.
