Queries :: Query Records With Both Duplicate Values And Different Values?
Jun 18, 2013
I'm trying to determine the SQL to return only those records in a table which have duplicate values in each of two fields, but different values in a third field. Here's an example:
Code:
AcctNum FoodType FoodClass
------- -------- ---------
A123 Apple Fruit
A123 Apple Fruit
A123 Grape Fruit
A456 Potato Vegetable
A456 Potato Perishable
A789 Carrot Vegetable
A001 Banana Fruit
For the above table, I'm trying to return records which have multiple entries for AcctNum + FoodType, but DIFFERENT values for FoodClass. So for the above table, the query would return:
It returns these two records because there is more than one record with for the AcctNum + FoodType (i.e. 'A456' + 'Potato'), but DIFFERENT values for FoodClass (i.e. one record has 'Vegetable' while the other has 'Perishable').
I have a table with a multi-field unique index: PatientID TestId TestDate Examiner
The problem is, date and/or examiner can be blank until that information is updated. I want those null values to be understood as actual values so that multiple instances of that "waiting to be updated" record do not occur. Is it possible for Access to understand my indexes in the following way?
I have a union query. I am pulling in data from two (almost identical) SQL views in two different databases.
My MS_Access application is linked to the two views
The issue is A.GroupId. In view finance_WILPMonthEndReview the field is set to NVARCHAR255 in view iq4bisfinance_3DMonthEndReview the field is set to NCHAR255.
This is my union query.
SELECT A.Dataareaid,A.a_year, A.a_month, A.GroupID, A.dimension, A.accountnum,A.companygroupaccount,A.account_type, C.groupiddesc,D.costcelldescription, B.PL1assignment, Round([A.SumOfActual_amt],2) AS ActAmt, Round([A.SumOfBudget_amt],2) AS BgtAmt
[Code] .....
When I link my Excel pivot table to the query I get two lines
I am using Access 2010 on a Windows 7 laptop. I need a query to provide a list of ID's that have more than one occurrence of IDandDate combined but haven't been successful getting past syntax errors.
Using this table structure as an example: ID - defined as text field Date - defined as date/time field TestValue
This legacy table contains a record for each test. The table should be unique based on the ID and Date combination but was never restricted to that rule. I am converting to a new table but need to identify the duplicate entries so they can be addressed by business folks.
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 trying to create a query that takes values from a search form and provides records. I was having issues with getting results when some boxes on the form were left blank. I found a solution to that and it worked with a small number of fields. However when I make the full form query (about 8-10 fields) and run it says the query is too complex. I wrote the sql as I could not get designer to do what I wanted. Attached is the sql that works and that which is "too complex".
I've got a query where a particular field can have duplicate entries. I do NOT want to limit the properties to only have unique values. On the contrary, I very much WANT to keep those but I DO want to have something indicating that the duplicates are there. I can create another Y/N or true/false field to indicate this if needed.
We are working on an Access (2007) database that is on a SharePoint Site (2007).
Currently the form is operational, but there is one last thing that would be nice to have.
The table is "Updated Headcount" which contains "EMP_ID" which are unique numbers stored as text.
In the event a new employee is entered in the system by another user on this site we would like to prevent any duplicate "EMPID"s from being entered and saved on the SharePoint, we would also like to alert the user and prevent the data from being saved.
All data is currently bound, so once the user makes a change it is made, no submit button is required.
We are running into some difficulties in doing a dlookup from the value entered and comparing to a column in the table.
TABLE - UPDATED HEADCOUNT COLUMN in UPDATED HEADCOUNT - EMPID FORM CELL user will input an EMPID - newEMPID FORM CELL used for a dlookup to compare what user has entered to what is already in the table - duplicateEMPID
So below is what we are trying to do, we are sure there are a few commands missing....
I'm using Access 2010. I need to calculate a score based on values selected in a table by looking up corresponding values in other tables. I have a "Project" form to create new entries into the Project table (see Table 1). When I create a new project record, I will select values for the Payback and Need fields by selecting options from a list. The Payback list is pointed at Table 2 and the Need list is pointed at Table 3. In the below example, I created the "ABC" project and selected "1 year" for the Payback field and "Repair" for the Need field. Pretty simple.
Now that I have the "ABC" project loaded to my Project table, I'd like to create a report that will show a "score" for this project. The score should be calculated as follows: Payback Impact + Need Impact. In this example, the score should be 30 (Payback Impact of 20 + Need Impact of 10).
I have a query with an INNER JOIN and ORDER BY that is working great. Now, using the same JOIN, I need to update values in one table with the values in another. I thought it would be simple until I learned you can't do an ORDER BY with an UPDATE. Is there another way to achieve the same result? If you remove the 'ORDER BY', the statement below doesn't produce an error but the results are not correct:
UPDATE TableA INNER JOIN TableB ON (Left(TableA.CDN,6))=(TableB.CDN) SET TableA.HCC = TableB.HCC WHERE TableB.HCC Like '241*' AND TableB.BBB = 'X' AND TableA.CCC = "1234" AND TableA.HCC IS NOT NULL ORDER BY TableB.HCC, TableA.CDN;
I have a query that must calculate the different between values in two different records, based on the date.
The underlying ORIGVALUES table contains:
Date; Value; Diff 1/10/15; 100; (this is what I am trying to calc) 1/11/15; 101; (this is what I am trying to calc) 1/14/15; 102; (this is what I am trying to calc)
What is the best way to have each record calculate the selected date value divided by the prior date value)? E.g.
For 1/11 the math is 101 / 100 (so the 1/11/15 record would show the result of 1.01) For 1/14 the math is 102 / 101 (1/11 to 1/14 represents a weekend)
I could copy the prior day values to the current day records and do that math easily but that is very redundant.
How do I count the number of records with values within specified ranges?
My database contains a field with values ranging from say 1 to 1000. I need to write a query to show count the number of records with values in ranges I specify in the query.
I'm looking for output such as
<100 - 50 records 101 - 500 - 30 records 501 -1000 - 50 records
i made a query to display students results after an exam. there are 12 subjects but a student chooses 8 from that. After an exam, the results are keyed in and a result slip is printed later. The problem is that the result slip displays all subjects including those not done by the student. I typed a criteria >0 in one of the fields and no records appeared. Is there a way that i can use to display only the subjects chosen and marks attained by a student and leave out the rest?
I have a many to many relationship, and one of my tables (the junction table) has only 2 fields (BookID & AuthorID). These fields together are set as primary key, in order to avoid duplicate records. Eventually, if i will try to put a duplicate record, i will get Access error's message "The changes you requested to the table were not successful because they would create duplicate values in the index, primarykey or relationship ..."
What is the best approach in order to check whether a duplicate record is going to be created, and if yes, i will get a customised error message rather than the above mentioned default error message ?
I need help creating a report that summarizes duplicated values. I need to write a query that groups payments of equal amounts (duplicate values only) for each vendor together. I need to show a group header containing the vendor number and name. I was using the Having Count(*) > 1 function but that only tells me which values are duplicates It doesn't display them. I need to display the duplicates.
i have a sub form which on the click of a button sets 4 fields
Private Sub Command8_Click() LastPaymentDate.Value = Date NextPaymentDate.Value = Date + 7 AmountPaid.Value = [Form_Frm_Customer]![Payments] [Form_Frm_Customer]![Payments Due By].Value = Date + 7 End Sub
It updates all the fields fine but i keep getting the error 'the changes you requested were not successful because they would create duplicate values'
I have checked the table and all fields are set to allow duplicates.
I have a form in a database for our products (doors). I have a button that duplicates one of these records (all new products are based on standard template records).
When this record is created a new product number is produced by the system which was the number of the original (template) record plus the customer enquiry number.
I want to be able to warn the user if they are trying to save this newly created record with a product number that already exists so that they can alter the number to be unique. It will also warn them if they re-number an existing record to another already existing product number. Since the field is defined as unique, at present the system says absolutely nothing and just doesn't save the newly created record which seems is a touch annoying!
I have tried several things with dlookup, dcount arguments but can't seem to get anything to work.
Hopefully someone here can point me in the right direction?
Can someone tell me how a primary key in the attached can be set on the index to duplicates OK yet, when you click on the indexes icon on the toolbar, the UR is set to be aprimary key..
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 a table called Department. One employee may belong to more than one department. So I created three tables, Emptable, Depttable, and DeptDatatable. The Emp table and The dept table both have a primary key. Emp# in Emptable to Emp# in Dept Data Table. Dept# in Depart Table Primary key to foreign key in Dept# key in Dept Data Table. In other words:
Employee One to Many Department Data both using Emp# Department One to Many to Department Data both using Department#
I have created a form for data entry for the young lady that enters the data. Right now, there are two entries in the department data for any employee that belongs to more than one department. My question is how do I create a form that allow the person that is entering data to only enter the employee in once and enter multiple values into the department field. How would it create then two entries into the Dept Data Table? I have been reading up about fields that allow duplicate data but this treats the fields like memo fields. I need to draw queries from Departments, so not sure if that would work. I also need the Department to be a list that they choose from.
This is a very quick question. I have a query what i need it to do is show me all values that equal 2 and any records that are blank, this is what the criteria looks like currently
Field: Month([FDate])
Total:Group By
Criteria: Month([DDay1])
Now the way this works is it only shows records where the field meets the criteria, in this case Month([FDate]) = 2
I need the criteria to say if Month([DDay1])=Month([FDate]) Or is equal to "" Then display records.
EDIT: I just found out how to view blank values but what if records for it dont even exist... i still want to show the other fields..
