Queries :: Excluding Duplicates - Show Only Unique Values
May 17, 2013
I have duplicate data in a cell, I want to hide duplicate data and display only non-duplicate data.. I changed the property sheet to only show unique values, but it keeps showing data I don't want to see...
WasteCategory WasteCategoryIDPK WasteCategory [H, N, U, etc]
I'd like to query the line items for each manifest so the end result has the manifest number (Manifest #0001) in a field and the designations (N, H, P, U) in fields on a report.
I want to know, by month, what the total extended price is for all customers. But some customers appear more than once in a month. So I also want to know the total extended price for the month, but I only want to include the extended price for each customer once, using only the record with the highest unit price (or extended price, qty for each customer is consistent), and ignoring additional records with the same customer in that month.
I am an excel user, and I could quickly do this with pivot tables... but I have too many records for Excel to handle this efficiently (it just keeps crashing!), so I thought I'd move to access... but I don't know how to use access! So I may need a little hand-holding here.
I've used this guide [URL] .... to only show unique values in a combo box. I can't get it to work, it just shows a load of blank values. If I run the expression builder part from the background, it works but it doesn't work in the combo box. Not sure what I can post to give more details?
I have imported a large number of emails into a table tbl_requests.
I had intended to have unique file tbl_requests.date_opened unique, but have ended up with a lot of duplicate records (i.e. tbl_requests.date_opened is not unique !). How to delete any duplicates? I have 15,000 records...
I have a unique query which lists all the films that we are screening over the next 3 months. I have added a COUNT field so that I can see how many of each films we are screening.
The problem is that i get duplicates of some films - and this may be because we may hold several copies of some films. I have attached two images which might explain this better!
What I could do with is knowing how to make it so that i get a list of films booked and how many of each, regardless of which copy of the film is used.
The SQL is:
Code: SELECT DISTINCTROW dbo_Films.[film name], Count(dbo_Films.[film name]) AS [CountOffilm name] FROM ((dbo_Films INNER JOIN dbo_filmCopies ON dbo_Films.ID = dbo_filmCopies.tblFilms_ID) INNER JOIN dbo_EventsFlicks ON dbo_filmCopies.ID = dbo_EventsFlicks.filmCopyID) INNER JOIN dbo_Venues ON dbo_EventsFlicks.venueID = dbo_Venues.ID WHERE (((dbo_EventsFlicks.datefield)>=#8/1/2015# And (dbo_EventsFlicks.datefield)<#1/1/2016#)) GROUP BY dbo_Films.[film name], dbo_Venues.southhub, dbo_Venues.northhub, dbo_Films.Specilaised ORDER BY dbo_Films.[film name];
I'm attempting to create an append query that will add new records only if there isn't an equivalent record already existing. Typically I would add the existing table to the query, and only add new records if the same do not exist. In this case, the table is maintaining records over time (start date and end date).
I'm checking if [t_temp_employees].[effective_date] <> [t_city_assignment].[start_date]. However, if the employee has historical entries it will still add a record (in fact, it'll add multiple records).
How can I append a new record only if one for the same time period does not exist?
Hi all, I know this is a real easy one, but I am not the smartest when it comes to access. Can you help me out.
I am running a crosstab query to count and sum records in my database. I have a fied called "Amount". In my form the user is not always required to enter an amount. When I run the query, I would like the results to exclude the records that have a null value or $0.00 in the "Amount" field.
How do I format the query to exclude those records?
I have a table that has multiple records (count >1). I used the find duplicate records and then made it a delete query, however, this resulted in deleting all the records that had count >1. I need to retain distinct record, and delete the extra records. Using select distinct.. I do not want to use VBA to achieve this, but at the same time be able to incorporate the steps in a module that would execute the queries in a sequential order and achieve the same results.
I have a client database that has recently had multiple duplicate entries. I need to reduce or negate this erroneous activity. I have a client table where I record amongst others, the following;
key [christian_name] [family_name] [dob] ......
I believe that to prevent duplicate entrie via form I have created an additional field called "unique" given it as a unique index which I want to have populated with the joined fields first_name & last_name & dob (IE johndoe01/01/90), and then as user enters a new client it wont allow a duplicate.
However I need to fill all the existing customers (3600+) with the relevant joined existing data. If I create an expression I can cajoin the fields in a select query but when I try to make an update query the same syntax comes up with empty fields.
select query sql that worked to show field ...
SELECT divers.christian_name, divers.family_name, divers.dob, [christian_name] & [family_name] & [dob] AS Expr1 FROM divers;
update query that was empty ..
UPDATE divers SET divers.[unique] = [christian_name] & [family_name] & [dob];
What expression do i use to count the number of patientID when there are duplicates (ie patient has come back for more than one visit but I just want to know the number of patients who visited (not how many times))
How can I run a query on the table attached to show the number of UR's that were operated on. As you can see some of the UR have more than two procedure dates so I want to exclude duplicates. i have tried "count" but that just gives a "1" value for each UR on each procedure date
I'm looking for a way to grab values from one table that match a criteria, and append them/update them to another, but only grab one value once. Example:
I have a database of parts that fit in certain profile sizes. Each profile size has multiple open locations. I need a query to grab a location, assign it to a part, grab a new location, assign it to the next part, etc, without assigning duplicate locations to different parts.
Right now, I'm doing this by using the First/Last aggregate functions, marking them as used, and looping it again and again until all have unique locations. Is there a better way to do this?
I have a material usage table that tracks material going into products...Oftentimes the same material will be used and multiple records will contain that material.
I want my query to return only records with unique material used. I'm clicking the "Unique Values" and "Unique Records" property setting but its not working.
I have a query with over 85,000 lines of data where each row has a unique id but the unique id appears multiple times within the table. For example, there is a unique numeric id tide to various types of pets across four columns. So the id number 1 could appear in four different rows each with different pets. See the first attachment "Original Table"
I want to be able to create a table that has one for for each unique id with all of the corresponding pet data. See the attached "Desired Table".
I am currently using the below code to query values that have a unique "OverrideDescription" and where by the "Upload Date" is always the latest.
SELECT t1.* FROM [DaisyServiceRates-Amended] AS t1 LEFT JOIN [DaisyServiceRates-Amended] AS t2 ON (t1.OverrideDescription = t2.OverrideDescription) AND (t1.[Upload Date] < t2.[Upload Date]) WHERE t2.OverrideDescription IS NULL;
However I also need to be able to do a unique count of the [OverrideDescription] field.
I have found methods whereby I can do use, but they all use a GROUP BY function, the issue being that when I use this method it prevents be from updating the values saying "recordset not updateable".
Any method that does not use the GROUP function. I did also try preforming the COUNT on a separate table and doing as JOIN, but this also prevented updates to the date.
I have one field where string contains several words separated by semicolon and my goal is to be able to remove duplicates within the string and keep only unique values. Here is an example:
I have a table - (Table A) that has 2 fields X and Y. I would like to write a query or script to make two new tables based on the unique values found in field X. In other words, all data where field X = 1 would be written to a new table called "1" and all data wehre field X =2 would be written to a new table called "2".I would like this done automatically.
Table A Field X Field Y 1 a 1 b 1 c 1 d 2 a 2 b 2 c
I have a problem with getting the right result with a query.
To this topic I attached a part of my database including 2 queries. The queries are almost the same, except the first field. In query 1 is the total 'Group By' and in query 2 'Count'.The other fields are parameters, which are the same in both queries.
My problem: If I run query 1 then the result is 31 rows with unique ID's. When I run query 2 the result is 35, because the query counts 4 duplicates.
The correct result I want is 31. That means count the unique ID's. I am able to show the ID's with query 1, but I am not able to count them correctly. I tried to add 'DISTINCT' in SQL view but that didn't help. Also other solutions written in this forum didn't work.
Thank you if someone (with more query/SQL experience) is able to help me... :o
Is there a way that in a query from several tables you can choose to exclude duplicates of a specific field?
In the query I'm trying to create I am going through and counting the number of customers in a certain time frame. I don't want to count a customer each time they buy something though, I only want to count them once. The dates of their purchases are held in a seperate table for purchases and the customer information is held in a customer table. The information I need is in both of these tables and each customer has an ID number which is how the two tables are joined.
When I tried using the DISTINCT code it still brought in all the purchases because the customer bought things on different dates. The only way I have ever used this, however, is to write SELECT DISTINCT at the beginning of the SQL instead of just SELECT. If there's another way to use it to do what I need I will try it as long as you tell me what it is.
How can I set up the query to bring in all the information I need but not duplicate the ID numbers?
I have designed an invoice for a project that shows the amount of money needed to be paid, some of this has already been paid and some hasnt, how am i able to make it so that the values that have been paid and therefore have been checked are not include in the query. please help.
I have the following dataset in a table called NR_PVO_120. How do i pick out a number (which can change but let's say, 6) of UNIQUE OtherIDs without excluding any OtherIDs under any fax numbers?
So, if you pick OtherID from Row7 you then also must pick OtherIDs from rows 8 and 9 because they have the same fax number. Basically, once you pick an OtherID you're then obligated to pick all OtherIDs that have the same fax number as the one you picked.
If the number requested (6 for this example) isn't possible then "the closest number possible but not exceeding" would be the rule.
For example, if you take OtherIDs from rows 1-10 you will get 6 unique OtherIDs but row 10 shares a fax with rows 11 and 12. You either need to take all 3 (but that will raise the unique count to 8, which isn't acceptable) or skip this OtherID and find one with a fax that has no other OtherIDs and that isn't on the result set already. My result of 6 UNIQUE OtherIDs will need to contain ALL OtherIDs under any fax the existing OtherIDs are connected to.
So one solution is to take rows 1-6, 26. Another is to take rows 1-4,10-14.
There will be many possibilities (the real dataset has tens of thousands of rows and the number of people requested will be around 10K), as long all OtherIDs connected to all faxes on the result set are part of the requested number (6 in this case) any combination would do.
A few notes.
1.Getting as close as possible to the requested number is a requirement.
2.Some OtherIDs will have a blank fax, they should only be included as a last resort (not enough OtherIDs for the requested number).
This is for a fax campaign, we need to make sure no fax number is faxed twice, that all people connected to that fax number are contacted under one fax sent.
i have one table in which ID is Primary ID with Different Values
Like
ID NAME PAN 1 A X 1 B Y 1 A X 2 C Z 2 C G 3 D U
it shows that ID 1 having 2 Name (A& B,with PAN, X & Y ,respectively).how can i get this that ID having More than 1 Value like 1 and how can i select only these records ID which having more than 1 value and how can i update values for 1 ID.
Year EventNumber CorrectiveActionNumber ResponsibleGroup Committment
Each event will have multiple corrective actions. For each corrective action assigned to a group, the "committment" is also assigned to them, but I also have to assigned a committment to our group (SRG). So this makes the query results show two records for each corrective action, one with the group assigned committment and one for my groups committment. I need a query that will show corrective actions that have the group committment assigned but not a corresponding SRG committment assigned. However since my query results in two separate records, I am unsure how to do this.
