Need Distinct Records Of Whle Table But Distinct On One Field
Sep 15, 2006
Hi, Wish if some one could help me ASAP.
I have a table which contains name, tel, email
i need to import only records which have distinct email.
I do need need to import data of all three fields but only which has distinct email.
As there are number of record which are duplicate.
They have different names but same email.
So i need to condition only for distinct email but dump the data in a new table with all three records.
so same names can have different email.
but same email can't have duplicate email.
So need only records which have distinct email.
Please help .......
Using a database 2010. I have a monthly import from a spreadsheet to one of my tables. Sometimes it has the same previous data from prior month or months that has not changed. I don't want to keep appending this data to my table if none of the fields have changed.
Is there a way to append data to table only if fields have changed in an append query? Ex. (Name, Address, PhoneNum, Rate) If all fields are the same; don't append. If one or more fields are changed; append.
I have a database with an import process which normalises incoming data and appends to various tables. No issues with that. I also have a function within that process which counts the number of new entries for a summary popup when the process has completed.This works by querying the staging table, prior to the append, into a recordset and using the .RecordCount to increment the count (multiple files can be imported at once so this effectively provides a running count, per file, to give a total for the whole import)
I thought it was working fine but this morning I noticed that the count which appeared on the popup was 1 greater than the number of actual new records. I checked the source files and noticed that, for whatever reason, there was a duplicate entry in there. So I presume that's why the count was out by 1.
There's no integrity issue in the main tables as the composite primary keys ensure that duplication shouldn't be a problem. Indeed, the record in question, duplicated in the source, appears only once in the main table post-import. So not too worried about that.
However, I need the count in the popup to be accurate (it tells the users how many new entries require further investugation). And what's puzzling me is that I use DISTINCT in the query, which I would have thought should eliminate any potential dupes in the recordset and thus provide the correct count. It seems it doesn't?
Code: Public lngNewBalancesTBI As Long ' Defined in a separate module... ------- Dim dbs As Database Dim rst As Recordset Dim strSQL As String
[code]....
Why the dupe, which is still present in the staging table, also makes it over to the recordset, even though I'm using DISTINCT?
I have a table with duplicate records (which is ok) and I want to return distinct data for each client.
It works fine when there is only two fields returned however, when I add a third field to the query it no longer returns only the Distinct records - I am getting Duplicates returned.
I.E
SELECT DISTINCT tblClient.ClientNo, tblClient.Name FROM tblClient
Works fine with only the Distinct records for each client returned
However
SELECT DISTINCT tblClient.ClientNo, tblClient.Name, tblClient.Address, tblClient.OrderValue FROM tblClient
Now returns Duplicates!
Is there a limit to the number of fields to be returned using DISTINCT or what else could be the problem? Should I be doing this some other way?
tbl_A has column "ID" with duplicates. tbl_B has column "ID" with distinct values.i want to find all the distinct IDs in tbl_A that are present in tbl_B.I've tried the following with no luck:
SELECT DISTINCT tbl_A.ID FROM tbl_A LEFT JOIN tbl_B ON tbl_A.ID = tbl_B.ID WHERE tbl_A.ID IN tbl_B.ID;
Below is a sample of the table with the data. I manually added the 1 and 0 to the hc_Year field. However, I would like to create an Update query that will add a 1 to the hc_Year if its the first instance of PIDM & regsYear and add a 0 to the records that are not the first instance.
i'm trying to get a count of how many customers made billing requests during the month of november. the query is based on one table in the database. some customers made multiple requests, but i'm looking for the number of different customers who made requests, not the total number of requests made. the following sql stuff weeds out the duplicate customer numbers and lists each unique customer number.
SELECT DISTINCT TBLBillingRequest.MemberID FROM TBLBillingRequest WHERE (((TBLBillingRequest.DateSCSCLogged) Between #11/1/2005# And #11/30/2005#));
my problem occurs when i try to to incorporate the count function like so.
SELECT DISTINCT Count(TBLBillingRequest.MemberID) AS CountOfMemberID FROM TBLBillingRequest HAVING (((TBLBillingRequest.DateSCSCLogged) Between #11/1/2005# And #11/30/2005#));
it gives me a count, but the count includes duplicate customer numbers as well, not the total of unique customer numbers, which is what i want.
any suggestions/help would be greatly appreciated!
Most employees have 10 to 15 rows. I only want to pull ALL rows for employees ONLY if there is a distinct count from DATE_PAID greater than 1. There are cases where an employee might have two pay checks generarted for the same PAY_DATE.
I'm creating a report for an imaginary "medical clinic's database", the intended function of which is described as follows: "Create a statistic that shows the total number of distinct drugs prescribed to a patient."
Where I'm at:
I've created a query called UniqueDrugs containing drug and patient info. The SQL is:
Quote:
SELECT DISTINCT Drugs.Drug_Name, Patients.[Patient _ID] FROM Patients INNER JOIN (Drugs INNER JOIN Prescriptions ON Drugs.[Drug_ID] = Prescriptions.[Drug_ID]) ON Patients.[Patient _ID] = Prescriptions.[Patient_ID] GROUP BY Drugs.Drug_Name, Patients.[Patient _ID] ORDER BY Patients.[Patient _ID];
The results of this query seem to be what I need. All I need is for the count formula that I use to return the number of distinct drug names there are that are related to a patient's ID.
I've created a report and I've put the following formula into a text box:
Where PID is the name of another text box in the report that contains the Patient ID that I want to compare to the drug names returned by the query.
However, this *always* results in #Error, no matter how I change the formula.I have been led to believe that syntax is not the issue, as the following formula worked as intended for a different task:
I am trying to write a query that will select distinct values from three columns. The table name is Hoods. The columns are C1, C2, and C3. All three columns contain colors and can have the same values, but I only need to have a particular color selected once. For instance, all three columns contain "Black", but "Black" should only be listed once. The result of the query will be used in a drop down list.
The following works for one column:
SELECT DISTINCT [Hoods].[C1] FROM Hoods WHERE C1<>"";
I have a table of data which includes a date field and also various other fields which may or may not be filled with data.I'm trying to populate a listbox with the months for which this data is missing (a separate macro will then loop through these months to fill the missing data) But I only want each distinct month to populate the listbox - not each individual date.
Code: strSQL = "SELECT DISTINCT month([EntryDate]), year([EntryDate]) FROM [SampleTable] WHERE [ValueField] Is Null" Me.lstSampleListBox.RowSource = strSQL
I am currently trying to make a form which will generate a report for the users. Currently the form has 3 combo boxes where users select which fields they want displayed from the table in the report. They also have sorting options next to them (Asc or Desc). I am now trying to put in a multi select list box under each combo box to allow users to filter the report to their liking. Currently I am trying to pull distinct values from the specific field of the table and display them in the listbox for users to select.
I have tried using vba to set me.filter1.rowsource = SELECT DISTINCT me.combo1 FROM EVAP_Database, but this doesnt seem to work. I have also tried a few other codes and still no luck.
Hello. I'm making a database to store movie info for a DVD collection. I have a table with fields: title, year, runtime and such. I want an indefinite number of genre to be associated with a movie, so I created a "genre" table and a junction table between that and the "movie" table. Now, on form I want to be able to filter a list of movies based on a genre selection from a combo box. The only way I can see to do this is to make the rowsource of the listbox a query with "tblMovie.MovieID, tblMovie.Title, tblJunction.GenreID" connected through MovieID. This would work except that if a movie is associated with more than one genre on the junction table, the movie appears on the list more than once. I want a movie to appear only once. That's my problem. Thanks in advance for the help.
I have a query with in excess of 20 fields. One of the fields is [POLICY NUMBER]. I want to use DISTINCT to only show rows of data where the Policy number is unique.
If I put DISTINCT after SELECT the query will only include results where the combination of values from all the fields are unique and I dont want this.
I am running a query in a combo box but for some reason the following SQL statement does not give me the result I am after. Which is to only displaying the distinct records. It continues to display the multiple occurrences of the records. I also tried distinctrow with no better results.....
I have a table with the follwing; ShopID, CustomerID, Month, Item_ref, Product Category
There are about one thousand shops. The CustomerID field is only unique per shop. I.e. all transactions for customer ID '002' in shop 1 will be for the same customer, but customer ID '002' could appear in another shop and will be a different customer, I want to be able to bring back a list of distinct customers, the number of items they have had and the product categories.
Has anyone got any ideas how I do this? I presume I would need to do a count distinct or something??
Hello, I have a strange problem: one of my comboboxe is looking up a column in one of my table. Some of the record can be duplicated so I decided to change SELECT to SELECT DISTINCT in my SQL for the row source but it doesn't seem to change anything. Is anybody's got an idea why?
I want to get disctinct count of InvoiceNo while summing up Amount by Date and CustomerID in one query. Firstly, I tried to use correlated query to count unique records but it failed. SELECT A.Date, A.CustomerID, (SELECT COUNT(B.InvoiceNo) FROM Table1 B WHERE B.Date = A.Date AND B.CustomerID = A.CustomerID ) AS CountOfDistInvNo, Sum(A.Amount) AS SumOfAmount FROM Table1 A GROUP BY A.Date, A.CustomerID;
The result of Count is not a unique count. Can anyone tell me what's wrong with this correlated query? :confused:
After hours of googling on internet, the solution I got is equivalent to querying on top of the resulting table from another query.
My final query is
SELECT B.Date, B.CustomerID, Count(B.InvoiceNo) AS CountOfInvoiceNo, Sum(B.SumOfAmount) AS SumOfAmount FROM (SELECT A.Date, A.CustomerID, A.InvoiceNo, SUM(A.Amount) AS SumOfAmount FROM Table1 A GROUP BY A.Date, A.CustomerID, A.InvoiceNo) AS B GROUP BY B.Date, B.CustomerID;
Is there a better solution than this in Access? :)
Tried several suggestions in the forum but haven't found one to match my needs.
I have one table, Jupiter and need to use this query
SELECT Jupiter.codename AS Build, Count(Jupiter.tooling_ind) AS [# Needing Tool], Count(IIf([tool_req_type]='OR',([requisition_no]))) AS [# Tooled], [# Tooled]/[# Needing Tool] AS [% Tooled], Jupiter.tooling_ind FROM Jupiter GROUP BY Jupiter.codename, Jupiter.tooling_ind HAVING (((Jupiter.tooling_ind)="Y"));
For each "codename", there is an attached "part_no" which can appear under a codename several times. The problem is that I need to count only one instance of the "part_no" for each "codename". So, my query looks like this: Build # Needing Tool #Tooled LP1 769 192
The # Needing Tool is counting every record that, say pn 10592 shows up in and I need it to be counted only once in each "Build"
I did try this suggestion I found with no results.
SELECT Jupiter.codename AS Build, Count(Jupiter.tooling_ind) AS [# Needing Tool], Count(IIf([tool_req_type]='OR',([requisition_no]))) AS [# Tooled], [# Tooled]/[# Needing Tool] AS [% Tooled], Jupiter.tooling_ind FROM (SELECT DISTINCT Jupiter.part_no FROM Jupiter)Jupiter GROUP BY Jupiter.codename, Jupiter.tooling_ind HAVING (((Jupiter.tooling_ind)="Y"));
I have a problem using distinct or distinctrow in one of my query. The result shown reflects all records instead of distinct records. May I know what may be the cause of the problem?
Query: SELECT DISTINCT Assets.*, Depreciation.DepreciationDate, Depreciation.DepreciationAmount FROM Assets LEFT JOIN Depreciation ON Assets.AssetID=Depreciation.AssetID;
I've searched on google for count distinct help but I had no luck. I'm counting 2 different columns and when the query is run the counts in both columns appear exactly the same. Also, I need a SUM distinct (if possible) to sum only where it is being counted in 'CountOfCar_Nr'. Here is my SQL....
