I have such query to combine data out of 4 tables:
— Category (100 records)
— PriceList (20'000 records)
— CheckDetail (10'000'000 records)
— CheckFinal (2'000'000 records)
In plain word, I'm looking for PriceList items, that are marked as children of Category.UniqID #2, then I would like to collect all CheckDetail.NUMER inset to define all sales value with such PriceList items. Futhermore, I'm looking for possobility to collect all CheckFinal.NUMERs.
The problem I have is:
It's not possible to make SELECT procedure three (3) time nested (SQLite.3), I think it's time to make JOINs but I have no experience in joining
CheckDetail is a HUGE data set, it's take 2 seconds to find just one PriceList item across 10 million records and I have 3'000 items in my query WHERE (Category.UniqID = 2)
In my case, I should lookup 3'000 times through 5'000'000 records, but I have 10 sets and the query will spend about 10 hours to complit.
Is JOIN will optimize query time? How to make such JOIN QUERY?
Is there any GUI tools to make query with constructor or something like that?
UPD:
http://sqlfiddle.com/#!5/50a93/2 (use SQL.js for inserting several rows of data)
WITH JOIN , you query would look like
SELECT
sum(CF.SUM) AS SUME,
strftime('%Y - %m', CF.CheckDate) AS CheckDate
FROM
PriceList
Join Category
on PriceList.CATEGORY = Category.UniqID
AND Category.UniqID = 2
JOIN CheckDetail CD
ON CD.NUMBER = PriceList.UniqID
JOIN CheckFinal CF
ON CF.NUMBER = CD.NUMBER
GROUP BY strftime('%Y - %m', CF.CheckDate);

I have a simple manufacturing job card system that track parts and labor for an assigned job.
It consists of a JobHeader table that holds the Job Card number (JobHeader.JobNo), ID of the part being manufactured (JobHeader.RegNo) and quantity to be manufactured (JobHeader.RegNo).
There is a child table (JobLabour) that tracks all the times that have been worked on the job (JobLabour.WorkedTime)
I'm looking for a query that will return the average time taken to produce a part accross the last 5 job cards for that particular part.
The following query
SELECT TOP 5 JobHeader.RegNo, JobHeader.BOMQty, sum(JobLabour.WorkedTime) AS TotalTime FROM JobHeader INNER JOIN JobLabour ON JobHeader.JobNo=JobLabour.JobNo
WHERE JobHeader.RegNo='RM-BRU-0134'
GROUP BY JobHeader.BOMQty, JobHeader.JobNo, JobHeader.RegNo
will return this:
But what I'm looking for is a query that will return the average BOMQty and average totalTime. Something like this:
Is there a way to do this?
Your question explicitly mentions the "last five" but does not specify how that is determined. Presumably, you have some sort of date/time column in the data that defines this.
In SQL Server, you can use apply:
select jh.*, jl.*
from jobheader jh outer apply
(select top (5) avg(BOMQty) as avg_BOMQty, avg(totalTime) as avg_totalTime
from (select top (5) jl.*
from joblabour jl
where jl.regno = jh.regno
order by jl.<some datetime> -- however you determine the last five
) jl
) jl;
You can add a where clause to the outer query to filter on one or more particular jobs.
If I understand you correctly this will do the work
this will work for 1 RegNo='RM-BRU-0134' at a time
with topFive as (
SELECT TOP 5 JobHeader.RegNo, JobHeader.BOMQty, sum(JobLabour.WorkedTime) AS TotalTime
FROM JobHeader
INNER JOIN JobLabour ON JobHeader.JobNo = JobLabour.JobNo
WHERE JobHeader.RegNo = 'RM-BRU-0134'
GROUP BY JobHeader.BOMQty, JobHeader.JobNo, JobHeader.RegNo
)
select RegNo, avg(BOMQty) as BOMQty, avg(TotalTime) as TotalTime
from topFive
group by RegNo
I am fairly new in Access and SQL programming. I am trying to do the following:
Sum(SO_SalesOrderPaymentHistoryLineT.Amount) AS [Sum Of PaymentPerYear]
and group by year even when there is no amount in some of the years. I would like to have these years listed as well for a report with charts. I'm not certain if this is possible, but every bit of help is appreciated.
My code so far is as follows:
SELECT
Base_CustomerT.SalesRep,
SO_SalesOrderT.CustomerId,
Base_CustomerT.Customer,
SO_SalesOrderPaymentHistoryLineT.DatePaid,
Sum(SO_SalesOrderPaymentHistoryLineT.Amount) AS [Sum Of PaymentPerYear]
FROM
Base_CustomerT
INNER JOIN (
SO_SalesOrderPaymentHistoryLineT
INNER JOIN SO_SalesOrderT
ON SO_SalesOrderPaymentHistoryLineT.SalesOrderId = SO_SalesOrderT.SalesOrderId
) ON Base_CustomerT.CustomerId = SO_SalesOrderT.CustomerId
GROUP BY
Base_CustomerT.SalesRep,
SO_SalesOrderT.CustomerId,
Base_CustomerT.Customer,
SO_SalesOrderPaymentHistoryLineT.DatePaid,
SO_SalesOrderPaymentHistoryLineT.PaymentType,
Base_CustomerT.IsActive
HAVING
(((SO_SalesOrderPaymentHistoryLineT.PaymentType)=1)
AND ((Base_CustomerT.IsActive)=Yes))
ORDER BY
Base_CustomerT.SalesRep,
Base_CustomerT.Customer;
You need another table with all years listed -- you can create this on the fly or have one in the db... join from that. So if you had a table called alltheyears with a column called y that just listed the years then you could use code like this:
WITH minmax as
(
select min(year(SO_SalesOrderPaymentHistoryLineT.DatePaid) as minyear,
max(year(SO_SalesOrderPaymentHistoryLineT.DatePaid) as maxyear)
from SalesOrderPaymentHistoryLineT
), yearsused as
(
select y
from alltheyears, minmax
where alltheyears.y >= minyear and alltheyears.y <= maxyear
)
select *
from yearsused
join ( -- your query above goes here! -- ) T
ON year(T.SO_SalesOrderPaymentHistoryLineT.DatePaid) = yearsused.y
You need a data source that will provide the year numbers. You cannot manufacture them out of thin air. Supposing you had a table Interesting_year with a single column year, populated, say, with every distinct integer between 2000 and 2050, you could do something like this:
SELECT
base.SalesRep,
base.CustomerId,
base.Customer,
base.year,
Sum(NZ(data.Amount)) AS [Sum Of PaymentPerYear]
FROM
(SELECT * FROM Base_CustomerT INNER JOIN Year) AS base
LEFT JOIN
(SELECT * FROM
SO_SalesOrderT
INNER JOIN SO_SalesOrderPaymentHistoryLineT
ON (SO_SalesOrderPaymentHistoryLineT.SalesOrderId = SO_SalesOrderT.SalesOrderId)
) AS data
ON ((base.CustomerId = data.CustomerId)
AND (base.year = Year(data.DatePaid))),
WHERE
(data.PaymentType = 1)
AND (base.IsActive = Yes)
AND (base.year BETWEEN
(SELECT Min(year(DatePaid) FROM SO_SalesOrderPaymentHistoryLineT)
AND (SELECT Max(year(DatePaid) FROM SO_SalesOrderPaymentHistoryLineT))
GROUP BY
base.SalesRep,
base.CustomerId,
base.Customer,
base.year,
ORDER BY
base.SalesRep,
base.Customer;
Note the following:
The revised query first forms the Cartesian product of BaseCustomerT with Interesting_year in order to have base customer data associated with each year (this is sometimes called a CROSS JOIN, but it's the same thing as an INNER JOIN with no join predicate, which is what Access requires)
In order to have result rows for years with no payments, you must perform an outer join (in this case a LEFT JOIN). Where a (base customer, year) combination has no associated orders, the rest of the columns of the join result will be NULL.
I'm selecting the CustomerId from Base_CustomerT because you would sometimes get a NULL if you selected from SO_SalesOrderT as in the starting query
I'm using the Access Nz() function to convert NULL payment amounts to 0 (from rows corresponding to years with no payments)
I converted your HAVING clause to a WHERE clause. That's semantically equivalent in this particular case, and it will be more efficient because the WHERE filter is applied before groups are formed, and because it allows some columns to be omitted from the GROUP BY clause.
Following Hogan's example, I filter out data for years outside the overall range covered by your data. Alternatively, you could achieve the same effect without that filter condition and its subqueries by ensuring that table Intersting_year contains only the year numbers for which you want results.
Update: modified the query to a different, but logically equivalent "something like this" that I hope Access will like better. Aside from adding a bunch of parentheses, the main difference is making both the left and the right operand of the LEFT JOIN into a subquery. That's consistent with the consensus recommendation for resolving Access "ambiguous outer join" errors.
Thank you John for your help. I found a solution which works for me. It looks quiet different but I learned a lot out of it. If you are interested here is how it looks now.

I have three tables that need to be joined in order to get monthly inventory data in return.
Table 1: TargetInventory
Table 2: TargetValue
Table 3: TargetWeight
[TargetInventory] does not change after being added the first time.
[TargetValue] is just a small table that includes prices of various types of metal.
[TargetWeight] is updated monthly as part of our inventory process. We INSERT new data, we never UPDATE old data.
Below is the relationship between these tables. (Sorry, I don't have the reputation points to post an image. Brand new here, so hopefully this makes sense.)
(* = UniqueKey)
--TargetValue-- --TargetInventory-- --TargetWeight--
*MaterialID <===| *TargetID <=====| *ID
Material |===> MaterialID |===> TargetID
PricePerOunce Length RecordDate
Density Width Weight
Thickness
DateInInventory
The TargetWeight table contains multiple records for TargetID (since a new one is added every month at inventory). That's good for me to track historical usage, but for the current inventory value, I only need the most recent TargetWeight.Weight to be returned.
I don't know how to do a CROSS APPLY from within another INNER JOIN, so I'm at a loss for how to do this (without switching to mySQL and just doing a LIMIT 1...)
I think it needs to look something like what's below, but I'm not sure how to finish the query.
SELECT
TargetInventory.TargetID AS TargetInventory_TargetID,
TargetInventory.MaterialID AS TargetInventory_MaterialID,
TargetInventory.Length,
TargetInventory.Width,
TargetInventory.Thickness,
TargetValue.MaterialID AS TargetValue_MaterialID,
TargetValue.PricePerOunce,
TargetValue.Density,
TargetWeight.ID,
TargetWeight.TargetID AS TargetWeight_TargetID,
TargetWeight.RecordDate,
TargetWeight.Weight
FROM
(TargetValue
INNER JOIN TargetInventory
ON TargetValue.[MaterialID] = TargetInventory.[MaterialID]
)
CROSS APPLY (
SELECT TOP 1 *
FROM .....
)
The following query works for me in Access 2010. It uses an INNER JOIN on a subquery to take the place of the CROSS APPLY (which Access SQL doesn't support). It assumes that there will be no more than one [TargetWeight] record for a given (TargetID, RecordDate):
SELECT
TargetInventory.TargetID AS TargetInventory_TargetID,
TargetInventory.MaterialID AS TargetInventory_MaterialID,
TargetInventory.Length,
TargetInventory.Width,
TargetInventory.Thickness,
TargetValue.MaterialID AS TargetValue_MaterialID,
TargetValue.PricePerOunce,
TargetValue.Density,
LatestWeight.ID,
LatestWeight.TargetID AS TargetWeight_TargetID,
LatestWeight.RecordDate,
LatestWeight.Weight
FROM
(
TargetValue
INNER JOIN
TargetInventory
ON TargetValue.[MaterialID] = TargetInventory.[MaterialID]
)
INNER JOIN
(
SELECT tw.*
FROM
TargetWeight AS tw
INNER JOIN
(
SELECT TargetID, MAX(RecordDate) AS LatestDate
FROM TargetWeight
GROUP BY TargetID
) AS latest
ON latest.TargetID=tw.TargetID
AND latest.LatestDate=tw.RecordDate
) AS LatestWeight
ON LatestWeight.TargetID = TargetInventory.TargetID
Alternative approach specifically for Access 2010 or later
If the above query bogs down with a large number of rows in [TargetWeight] then another possible solution for Access 2010+ would be to add a Yes/No field named [Current] to the [TargetWeight] table and use the following After Insert data macro to ensure that only the latest record for each [TargetID] is flagged as [Current]:
Once that is done, the query would simply be
SELECT
TargetInventory.TargetID AS TargetInventory_TargetID,
TargetInventory.MaterialID AS TargetInventory_MaterialID,
TargetInventory.Length,
TargetInventory.Width,
TargetInventory.Thickness,
TargetValue.MaterialID AS TargetValue_MaterialID,
TargetValue.PricePerOunce,
TargetValue.Density,
TargetWeight.ID,
TargetWeight.TargetID AS TargetWeight_TargetID,
TargetWeight.RecordDate,
TargetWeight.Weight
FROM
(
TargetValue
INNER JOIN
TargetInventory
ON TargetValue.[MaterialID] = TargetInventory.[MaterialID]
)
INNER JOIN
TargetWeight
ON TargetInventory.TargetID = TargetWeight.TargetID
WHERE TargetWeight.Current = True;
To maximize performance, the [TargetWeight].[TargetID] and [TargetWeight].[Current] fields should be indexed.
SELECT TargetInventory.TargetID AS TargetInventory_TargetID,
TargetInventory.MaterialID AS TargetInventory_MaterialID,
TargetInventory.Length,
TargetInventory.Width,
TargetInventory.Thickness,
TargetValue.MaterialID AS TargetValue_MaterialID,
TargetValue.PricePerOunce,
TargetValue.Density, Weight.ID,
Weight.TargetID AS TargetWeight_TargetID,
Weight.RecordDate,
Weight.Weight
FROM TargetInventory
INNER JOIN TargetValue ON TargetValue.[MaterialID] = TargetInventory.[MaterialID]
CROSS APPLY (
SELECT TOP 1 *
FROM TargetWeight
WHERE TargetID = TargetInventory.TargetID
ORDER BY RecordDate DESC
) AS Weight
I have two tables: EQUIPMENT and WORKORDERS.
EQUIPMENT returns the count of Equipment against a particular depot by the type of Equipment:
MAINTDEPOT EQUIPCOUNT EQUIPTYPE
1 44 MC
2 20 MC
3 5 MC
1 20 FS
2 3 FS
3 10 FS
...and so on. These counts rarely change unless a new bit of kit is put in.
I need to join a count of WORKORDERS to this table, but the work orders have a COSTCENTRE of either A B or E. This is so that I can generate a percentage of equipment with workorders.
I've joined the tables, but when I add a parameter filter to the WORKORDERS COSTCENTRE column the Count of EQUIPMENT changes, and I need it to stay the same.
I'm guessing I need to use subqueries to ensure that the left subquery remains static whilst the filter only changes the right hand one. Does anyone have any idea how I do this?
Here's my current query:
SELECT E.E_MAINTDEPOT, E.E_EQUIPCOUNT, C.Category, E.MYORDER, E.W_WORKCOUNT,
E.E_NOWO, E.W_HRS, E.E_QA, E.E_EGI, E.E_CLASS,
ISNULL(ROUND(CAST(E.E_NOWO AS Float) /
CAST(E.E_EQUIPCOUNT AS Float) * 100, 2), 100) AS RESULT,
SUBSTRING(E.E_CLASS, 1, 1) AS EM_CLASS
FROM (
SELECT T.E_MAINTDEPOT, COUNT(T.EQUIP_NO) AS E_EQUIPCOUNT,
SUM(C.W_WORKCOUNT) AS W_WORKCOUNT,
COUNT(T.EQUIP_NO) - SUM(C.W_WORKCOUNT) AS E_NOWO, T.MYORDER,
T.E_QA, T.E_EGI, T.E_CLASS, SUM(C.W_HRS) AS W_HRS
FROM EQDType AS T
FULL OUTER JOIN EquipWOCount AS C
ON T.EQUIP_NO = C.EQUIP_NO
GROUP BY T.MYORDER, T.E_MAINTDEPOT, T.E_QA, T.E_EGI, T.E_CLASS, C.W_FUNCTION
) AS E
INNER JOIN EQDCategory AS C
ON E.MYORDER = C.Myorder

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.
