Queries :: Subquery Top X Of Random Rows Not Working
Jun 2, 2013
I'm doing a subquery to select the top 5 of products for each supplier. The selection needs to be done randomly on the products for each supplier. For this I have made the following query (based on Allen Browne's example):
SELECT tblProducts_temp.SupplierID, tblProducts_temp.GTIN
FROM tblProducts_temp
GROUP BY tblProducts_temp.SupplierID, tblProducts_temp.GTIN
HAVING (((tblProducts_temp.GTIN) In (SELECT TOP 5 Dupe.GTIN
FROM tblProducts_temp AS Dupe
WHERE Dupe.SupplierID = tblProducts_temp.SupplierID
ORDER BY RND(Dupe.GTIN) DESC)))
ORDER BY tblProducts_temp.SupplierID, tblProducts_temp.GTIN;
The query returns a random number of products, but not a top 5. So for supplier X one time 3 products and the next time for supplier X 7 products.The query without the RND function, so just the top 5 works fine:
SELECT tblProducts_temp.SupplierID, tblProducts_temp.GTIN
FROM tblProducts_temp
GROUP BY tblProducts_temp.SupplierID, tblProducts_temp.GTIN
HAVING (((tblProducts_temp.GTIN) In (SELECT TOP 5 Dupe.GTIN
FROM tblProducts_temp AS Dupe
WHERE Dupe.SupplierID = tblProducts_temp.SupplierID
ORDER BY Dupe.GTIN DESC)))
ORDER BY tblProducts_temp.SupplierID, tblProducts_temp.GTIN;
We are developing a complaints tool. Each completed complaint needs to be signed off by 3 leads and I'm hoping to display the progress of this in a form. Obtaining the first is simple and I was able to do that relatively quickly. The subsequence ones are now giving me a headache as it doesn't seem I can reference the initial subquery field in the others.Here's what I have so far:
Code: SELECT COMPLAINT_TBL.COMPLAINTID, COMPLAINT_TBL.CASENUMBER, COMPLAINT_TBL.COMPLAINTANTFORENAME, COMPLAINT_TBL.COMPLAINTANTSURNAME, BUSINESSUNIT_TBL.BUSINESSUNIT, COMPLAINT_TBL.FINALRESPONSEDATE, (SELECT TOP 1 [SIGNOFF_TBL].[SIGNOFFDATE] FROM [SIGNOFF_TBL] WHERE [SIGNOFF_TBL].[COMPLAINTID] = COMPLAINT_TBL.COMPLAINTID ORDER BY [SIGNOFF_TBL].[SIGNOFFDATE] DESC) AS FIRSTSIGNOFF,
I have a subquery on a table which got the previous and next rows from a table. This worked fine, until I started replacing my table with real data instead of dummy-data. I now receive the "at most one record can be returned by subquery" error every time I run it. I checked that I do not have any identical rows.
My query:
Code: SELECT z.DateFrom, z.DateTo, z.ArticleID, z.retailerID, z.Actuals, z.Statistical, (SELECT y.Actuals FROM tblActuals AS y WHERE (y.retailerID=z.retailerID) AND (y.ArticleID=z.ArticleID) AND ((DatePart("ww",z.DateFrom,2,3)-1)=DatePart("ww",y.DateFrom,2,3))) AS ActualsMin1 FROM tblActuals AS z;
I append new rows via a VBA-script from another table.
I wrote a query to return the TOP 32 items for a key. Works fine:-
SELECT TOP 32 [my Disks Coefficients sub].[thier Disk ID] FROM [my Disks Coefficients] AS [my Disks Coefficients sub] WHERE [my Disks Coefficients sub].[my Disk ID]=1 GROUP BY [my Disks Coefficients sub].[thier Disk ID], [my Disks Coefficients sub].coefficient ORDER BY [my Disks Coefficients sub].coefficient;
I then plugged this into a query in the WHERE clause using In (Select Top .....;); [changing the =1 condition to pick up the correct id from the emcompassing query]:-
SELECT [my Disks Coefficients].[my Disk ID], [my Disks Coefficients].[thier Disk ID], [my Disks Coefficients].coefficient FROM [my Disks Coefficients] WHERE [my Disks Coefficients].[thier Disk ID] In (SELECT TOP 32 [my Disks Coefficients sub].[thier Disk ID] FROM [my Disks Coefficients] AS [my Disks Coefficients sub] WHERE [my Disks Coefficients sub].[my Disk ID]=[my Disks Coefficients].[my Disk ID] GROUP BY [my Disks Coefficients sub].[thier Disk ID], [my Disks Coefficients sub].coefficient ORDER BY [my Disks Coefficients sub].coefficient;);
This runs fine but the the number of items returned is for each key is less than if I run the Top query by itself for each key seperately? So when I run it stand-alone for ID 1 I get 127 rows (there are many equal coefficients); when I run it as a sub-query I get only 121 rows for ID 1!
I have a form with a subquery on it that shows all of the records that the form is based upon. The subquery and form are linked already, so whatever record I change to on the form, the subquery will follow. The records are chronologically ordered by date in ascending order. Depending on what day the form is on, I want to be able to highlight the rows/records of that particular week automatically in the subquery. I was just wondering what method I can use to do the highlighting/selecting of the records if there is such a thing. Hope I was clear...THANKS! =)
Extended Cost] and salestran.[Extended Price] for each salestran.[SKU Code/Number], Count the number of unique customers, salestran.[Customer Code/Number], per SKU for any transactions equal to or after salestran.[Transaction Date] 11/1/2014.
Problem is, doing a regular count on the Customer field returns an incorrect value. It counts the number of times the sku appears within the given date range, ie 6 transactions with 2 customers, my count says 6. I need a distinct count on the customer, for the above example I want to see 2. Here is the code I have so far which yields an error of "At most one record can be returned.." distinct count in my Select statement along with the other fields I want to see, ie Summary data and SKU.
SELECT Salestran.[SKU Code/Number], (SELECT COUNT(cd.[Customer Code/Number]) AS Count FROM (SELECT Distinct [SKU Code/Number], [Customer Code/Number] FROM Salestran) as cd GROUP BY cd.[SKU Code/Number]) AS [Number of Customers] FROM Salestran WHERE (((Salestran.[Transaction Date])>=#11/1/2014#)) GROUP BY Salestran.[SKU Code/Number];
I need to select a record with the latest (max) date along with associated values that go along with that record. However, some records have the same date. Initial query sorts by Asset_ID and Date (Desc)...A second query against the initial query then groups by Asset_ID, taking the Max Date and First Switch and Port...Results show the latest date but with a different Switch and Port
I have a one-to-many query which I would like to add a subquery to eliminate all but the TOP 1 of a field.
Here is the SQL:
Code: SELECT QrySitesBatteries.SiteKey, QrySitesBatteries.SITEID, QrySitesBatteries.Battery FROM QrySitesBatteries WHERE (((QrySitesBatteries.Battery)=[Forms]![FMHome]![Battery])) OR ((([Forms]![FMHome]![Battery]) Is Null)) ORDER BY QrySitesBatteries.SITEID;
And I would like to only show the TOP 1 of the SiteKey field.
So, I think I have to add the subquery before the ORDER BY, but how to do it?
At most one record can be returned by this subquery. (Error 3354)
This is my SQL:
SELECT Students.[Student ID], Students.[Student Name] FROM Students WHERE (((Students.[Student ID])=(SELECT [Student ID] FROM [Student_Sports] WHERE [Sporting Team] = [Forms]![SV_Teams]![txtTeam])));
I have a race league, I want to select the top 10 point scores for each member.
I have read the Allen Browne article (and many others) and tried many variations on his code but cannot get this working.
I face two issues - The ORDER by clause has no effect, points are not sorted with largest first - Access being unable to differentiate between scores with the same value and returning additional records. I have added an "Event" field to make the record unique, but this does not seem to work.
Query code is
SELECT qLeague.Member, qLeague.Event, qLeague.Points FROM qLeague WHERE qLeague.Points IN (SELECT TOP 10 Points FROM qLeague AS Dupe WHERE Dupe.Points= qLeague.Points ORDER BY Dupe.Member, Dupe.Points DESC ) ORDER BY qLeague.Member ASC, qLeague.Points;
This returns more than 10 results per member:
Member Event Points Alex Peters SDMC North Weald Sprint 3 Alex Peters HCAAC Debden May 3 Alex Peters GB/Harrow TAMS NW Sprint 4 Alex Peters HCAAC Debden Sprint 5 Alex Peters Llys y Fran Hillclimb 6
I have an issue with a code that I have in a form which adds rows in a table as many times as categories chosen from a list. However, the code is not working correctly: it adds the information and creates a row with a category in blank, in addition to the rest of the rows with one of the chosen categories. I would like for this not to happen, to add only as many rows as the categories chosen.
My code is the following:
Private Sub cmdUpdate_Click() Dim valSelect As Variant, MyDB As DAO.Database, MyRS As DAO.Recordset Set MyDB = CurrentDb() Set MyRS = MyDB.OpenRecordset("Tasks", dbOpenDynaset) MyRS.MoveFirst
I have a table of accounts and a table of rates. There is a one-to-many relationship between them (i.e. each account can have multiple rates, each with their own - unique - effective date)
I'm trying to build a query which will show me all of the accounts in the accounts table and the most recent rate (based on the effective date) for each of those accounts.
This is as far as I've gotten with the SQL :
Code: SELECT [tblAccounts].[AccountID], [tblAccounts].[AccountNumber], [tblAccounts].[AccountName], [LatestRate].[IntRate], [LatestRate].[EffectiveDate] FROM [tblAccounts] LEFT JOIN (SELECT TOP 1 [tblRates].[AccountID], [tblRates].[IntRate], [tblRates].[EffectiveDate] FROM [tblRates] ORDER BY [tblRates].[EffectiveDate] DESC) AS LatestRate ON [tblAccounts].[AccountID] = [LatestRate].[AccountID]
But this can't work because the [LatestRate] subquery can only ever return one record (i.e. the most recent rate across all of the accounts)
I need the most recent rate for each of the accounts in the main query
(FYI - I use an outer join as it is possible for no rate to be available in the rates table for a given account, in which case I want to return the null value rather than omit the account from the resulting dataset...)
I've created the following but it keeps coming up with the error message You tried to execute a query that does not include the specified expression 'ICE Team' as part of an aggregate function.
SELECT ztSub.[Master Sheet].[ICE Team], ztSub.[date], Count(ztSub.[Count]) FROM (SELECT [Master Sheet].[ICE Team],[Master Sheet].[Visit Date (planned for)] AS [date],Count([Master Sheet]![Visit Date (planned for)]) AS [Count] FROM [Master Sheet] UNION SELECT [Master Sheet].[ICE Team],[Master Sheet].[Date retasked to?] AS [date], Count ([Master Sheet]![Date retasked to?]) AS [Count] FROM [Master Sheet] ) AS ztSub GROUP BY ztSub.[Master Sheet].[ICE Team];
I am not real sure whether or not this can be done with a query, but here goes. I have a query randomly selecting the top 6 from a selected group.
SELECT TOP 6 tblConsortium.ContactID, tblConsortium.RandomID, patients.LastName & ", " & Patients.Firstname AS [Employee Name], Contacts.Company AS [Company Name] FROM patients INNER JOIN (Contacts INNER JOIN tblConsortium ON Contacts.ContactID=tblConsortium.ContactID) ON patients.PatientID=tblConsortium.PatientID WHERE (((tblConsortium.ContactID) In (SELECT ContactID FROM tblConsortium GROUP BY ContactID HAVING Count(*) <25))) And (((tblConsortium.PatientID)=Randomizer())=0) ORDER BY Rnd(IsNull(tblConsortium.patientID)*0+1);
What I would like to do now is: The randomly selected Employees need to have a randomly selected TEST. There are only 3-Test to choose from. I have placed the TESTS in a separate table and entered 20 of TEST1, 4 of TEST2, and 1 of TEST3. I then set a query randomly shuffling these items. I need these TESTS to randomly be assigned to the randomly selected Employees above.
I would greatly appreciate any thoughts or help… Thanks Enviva
Have a table (tblDailyResults) with 4 fields (ID,TestName,Result,TestDate). It contains a snapshot of about 1,000 records. All fields have data except "Result", which is null. I also have a table (tblResults) with 3 fields (ID,TestName,Result), it contains about 100,000 Records of historical results. What I need to do is Update the "Result" field in "tblDailyResults" with a randomly select value from tblResults where the two testname match.
I have two tables, one table Data has member(SUBSCRIBER_ID) data including service rep(UserName). Another table ServCoord has data including service rep and their manager. What I am trying to do is pull 5 random accounts per service rep. I can pull 5 random accounts, but not per service rep. I have currently 77 service reps. Is there any way I can pull 5 random accounts per service rep? Here is my starting point so far.
SELECT TOP 385 [Data].SUBSCRIBER_ID, Rnd(1) AS Expr1, [Data].UserName, Rnd(Len([UserName])) AS Expr2 FROM ServCoord INNER JOIN [Data] ON ServCoord.ServCoord = [Data].UserName GROUP BY [Data].SUBSCRIBER_ID, Rnd(1), [Data].UserName, Rnd(Len([UserName])), [Data].SUBSCRIBER_ID, [Data].UserName HAVING ((([Data].UserName)<>"NULL")) ORDER BY [Data].UserName, [Data].SUBSCRIBER_ID;
I am trying to create a database to link to an online auction site (not ebay) and I want to create a query that randomly generates auction end time and auction length for all listings. I have tried int(rnd()) and various versions but can only generate the same number for all fields in the query.
I am fairly new to Access 2013 but am trying to create a query that will select random records from three totally unrelated tables and display the results together as if one table -- think video slot machine wheels. Each table has two fields - ID which is the primary key and NAME. The data in the tables are names of states, names of colors, and types of animals. Each table has a different number of records. My end result is a table that selects X number of random records from each table and displays them side by side like this:
Desired Result: Animal Color State cat red Ohio dog blue Texas fox green Iowa
I have been able to create three individual queries that will pull X number of random records by using:
SELECT TOP 10 Animals.[ID], Animals.[Name] FROM Animals ORDER BY Rnd(-(100000*[ID])*Time()); SELECT TOP 10 Colors.[ID], Colors.[Name] FROM Colors ORDER BY Rnd(-(100000*[ID])*Time()); SELECT TOP 10 States.[ID], States.[LongName] FROM States ORDER BY Rnd(-(100000*[ID])*Time());
Using the three queries above I get three separate lists. how to make one query that will randomly pull from all three tables and make the display above?
CustomerID (Alpanumeric) AttendDate (General Date) Area (Alphanumeric)
Is is possible in a query to pull back 100 random CustomerID's on a set AttendDate. For example I have 1000's of Customers who attend each day, I want to do some Data Quality on 100 Random Customers.
I have a form which allows the user to add new records to a table. After the user had entered all the information into the form, they click a command button to add the record. In addition to adding the new record, my command button runs an query which is supposed to generate a random number between 1 & 1,000,000,000 and update the record ID field with that number.
Here is the formula I have been using in the "update To" now of my query: Int((1000000000-1+1)*Rnd()+1)
My problem is that I keep getting duplicates. You would think that the chances of getting a duplicate number would be pretty small with this large of a range, but I get a duplicate almost every time.
I have tried indexing (No duplicates) the field in the table, but that did not work. When my query generated a duplicate number, the record was just not added to the table.
I also tried a two step approach: 1-Make a table of all in use record ID numbers from my table (tblIdNo) 2-Update new record with a random number that is not in tblIdNo
This was a no-go too
How to build an update query that will update each new record added to the table with a random number between 1 & 1,000,000,000 without any duplicates? This seems like it should be so simple, and I am starting to get really frustrated.
I would prefer to accomplish this through a query/queries (if possible) rather than with 100 lines of code. This database is not for me, it's for another group, and the individuals in this group are totally freaked out by code.
I'm trying to insert 10% of a dataset from dbo_billing into another table Random_Temp. Another form is open when this query is to be ran that passess in the billyear and billmonth... I'm sure it's a syntax issue as I can isolate the random number part and it displays the appropriate data, I just can't re-write it to insert into the other table:
INSERT INTO Random_Temp ( indx, peopleId, audited ) SELECT TOP 10 PERCENT b.indx, b.peopleId, b.audited FROM dbo_Billing AS b WHERE (((b.billYear)=[Forms]![billing]![billyear]) AND ((b.billMonth)=[Forms]![billing]![billmonth]) AND ((b.recertifying)=-1)) ORDER BY Rnd(-(1000*b.indx)*Time());
I'm trying to create a query that generates random numbers for each record, sorts them by that field, then selects the top record. This should randomize the record being selected.
I can use the Rnd([ID]) function which does appear to generate a random number. Problem is that each time I exit the program and come back in, it always selects the same record. When I remove the Top = 1, to show all the records, every row does have a different random number but it does not appear to be sorting by this field.
If I run the query, here is the number I get: 0.98609316349029
Exit the program, restart, and run the query again: 0.98609316349029
If I refresh the query, the second and third time does appear to be random but the first result is always the same. how to generate truly random numbers?
Is it possible to run a SQL command to update a field within a table with random numbers?
More specifically - random long integers linking back to an ID (autonumber) field in another table?
Background to this is, I have multiple static data tables related to each other by long integer identifiers (autonumbers)
The structure is fine but I haven't been provided with the actual data yet - but for development purposes, I need to work on other functionality which requires that this data be present.
So I want to fill my table with dummy data such that I can go off and work on the remaining functionality, but then just go back and clear it all out once I get the actual data.
I have one 'main' static table, which links back to other tables, which I have already populated with dummy static (i.e. company names, locations etc) Now I want to go into my main table and populate those fields in each record with a random ID. I don't mind doing this field-by-field (there's only a handful) but I've a lot of records in there (~1000) so I'd rather not do this record-by-record.
I have a query which returns a calculated percent. I have ordered that in descending order, and now want to see the top 50. So (In Access 2010) I entered 50 into 'Return'. But it returns all of the records!
Is this because pct is a calculated field? How can I correct this? The SQL seems to be correct.
Code:
SELECT TOP 50 HeciFail1.POHECI, HeciFail1.POQTY, HeciFail1.FAILQTY, IIf(Nz([FAILQTY])>0,Round(100/([POQTY]/[FAILQTY]),0),0) AS PCT FROM HeciFail1 ORDER BY IIf(Nz([FAILQTY])>0,Round(100/([POQTY]/[FAILQTY]),0),0) DESC;
