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;
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 .......
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?
I have patients and their details all listed in onetable.

Ani ideas?
I have one table with 250 fields and hundreds of records. Each field represents a computer we have and the records in that field represent the type of applications we have on that computer. So the table looks like this:
Computer 1..........Computer 2.......... Computer 3........ Computer 250
Microsoft...............Google.................... .Paint.....................Microsoft
Windows Hotfix......Security Updates.......Java ......................Google
Java.....................Mediaplayer.............. Google.....................Java
As you can see, most computers have the same applications, but some have applications that others do not. I just need the list of applications we have from all computers. Meaning each app is listed only once.
I just need each application listed once. So I was trying to come up with a way to delete all the duplicates or use a Totals query to group the apps but since my table has 250 columns I'm not really sure how to go about it. What kind of query would be best to make this work?
I have a table with associate names and rankings for each month. I need some way to find out which associates appear in 2 consecutive months with a certain rating. I have a query that will allow you to key in which month you want to look at, but I can't figure out how to write the query to return results only for those associates that appear twice in the months chosen. For example:
John Doe was rated 1.5 in May and 3 in June.
Jane Doe was rated a 1.5 in May and 1.5 in June.
I want a query that will allow me to put in May and June as the criteria as well as < 2 for the rating and only return those that show in both months...
There are three tables. An [Action Register] table, a [Calls] table and a [tblContacts] table. The Contacts are common to both.
The Calls table records calls to customer by date
The Action Register table records issues that Customers send in by Open date.
I am trying to make a query where we see the latest date the customer was contacted regardless of which table.
I created two queries.
qryLastCallDate finds the max date from the Call table:
SELECT Max(Calls.CallDate) AS MaxOfCallDate, tblContacts.ContactName
FROM Calls LEFT JOIN tblContacts ON Calls.ContactID = tblContacts.ContactID
GROUP BY tblContacts.ContactName
ORDER BY Max(Calls.CallDate);
qryLastIssueDate finds the max date from the Action Register table:
SELECT Max([Action Register].Open) AS MaxOfOpen, tblContacts.ContactName
FROM tblContacts RIGHT JOIN [Action Register] ON tblContacts.ContactID = [Action Register].Contact
GROUP BY tblContacts.ContactName
ORDER BY Max([Action Register].Open);
The problem I am having is that if I use Left Join I can see all the records from the Calls table but not all from the Action Register table. And vis versa if I use Right Join. This is because sometimes we have calls but no issues in the Action Register table and sometimes issues with no calls.
This is my Left Join query using a Min Max Module I found here: [URL] ....
SELECT qryLastCallDate.ContactName, qryLastCallDate.MaxOfCallDate, qryLastIssueDate.MaxOfOpen, qryLastIssueDate.ContactName, DateValue(MaxOfList([MaxOfCallDate],[MaxOfOpen])) AS [Last Contact], ([Last Contact]+21) AS NextCall
FROM qryLastCallDate LEFT JOIN qryLastIssueDate ON qryLastCallDate.ContactName = qryLastIssueDate.ContactName;
How do I get to see ALL the records from both queries.
I am looking for a query that will return records from a table that have related records in another table. Opposite to the Unmatched Query Wizard.I have two tables: tblSupplier and tblSupplierProducts.The two tables are related by the field "SupplierId".I need the query to only return Suppliers that have Products.
View 3 Replies View RelatedI have a survey database that I've been using for the last year for monthly auditing of employees files. I need to be able to get monthly audit scores for each employee but grouped by their manager. The problem I'm having is employees have moved between managers throughout the year, so employees that are listed under Manager 2 now were actually working for Manager 1 when the audits occurred.
ie. Audits occurred Jan - April for Employee 1 while they were assigned to Manager 1. Employee 1 moved to Manager 2s team in May. So when running monthly reports for the year Employee 1 audits should fall under Manager 1 for Jan-April and Manager 2 for May-Dec.
I do have a history table set up like:
tblEmployeeHistory
ID (PK)
EmployeeID (FK to Employee table)
ManagerID (FK to Manager table)
MoveDate (date employee assigned to manager)
The Employee table is set up like:
Employee ID (PK)
EmployeeName
ManagerID (FK to Manager table)
The Manager table has the ManagerID and ManagerName.
That's the employee side of things; then I have the tables that store the audit results:
tblAudit
AuditID
FileNumber
AuditDate
EmployeeID (FK to employee table)
tblAuditResults
AuditID; QstnID (Composite PK, QstnID is FK to tblQuestions)
Answer
How can I use AuditDate and MoveDate to relate audits to the managers the employees were under when the audits occurred?
I have a table with the following values.
EMPLLOYEE_ID
JOB
PAY_DATE
LOCATION
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.
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'm using an UPDATE query to update records in one table (tblMain) from another table (tblTemp)
Here is my SQL :
Quote:
UPDATE [tblMain]
INNER JOIN [tblTemp] ON [tblMain].[MainField1] = [tblTemp].[TempField1]
SET [tblMain].[MainField2] = [tblTemp].[TempField2];
I only want to update the records in tblMain which have a corresponding record in tblTemp (linked by MainField1 / TempField1)
If any record doesn't appear in tblTemp, I want tblMain to retain the existing value for that record.
However, it appears that in such situations, the record in tblMain has it's MainField2 value set to null / ZLS.
I've tried using LEFT JOIN and RIGHT JOIN and also tried WHERE clauses but the result is the same every time.
I have an Access 2007 application that has a Parts Table that contains a list of automotive parts.I have attached a screen shot (parts.jpg) showing the structure.I have another table called Web_Parts that has exactly the same structure as Parts. The Web_Parts table gets its data from a CSV import that I do that is data extracted from an MySQL database used by an eCommerce website.
You will notice that there is a field called "Web_Product_Id" (number). This is the unique ID for each of the products that I have exported from the Web shop system. I need to regularly (probably every couple of weeks), export out of the web shop system and import into the Access environment.
Due to the fact that the data in the web shop system may change (pricing, description, add new items, delete new items etc), I need to find a way that I can simply update any existing records in the Parts table with any new information contained in the Web_Parts table......
I have a table which lists amendments (amendments history file) which need to take effect of another table (M0070), I can select the records fine and so the sub query looks to be okay but I'm missing something (probably obvious) in the deletion query where by it does only delete the records selected but everything (I know that the asterisk is wrong in the code below but I'm not sure what to replace it with).
At this point I'm trying to delete all records for a specific employee on a specific contract (they can be 1 or more employee records for that individual on a contract - and they could exist on multiple contracts).
DELETE *
FROM M0070
WHERE EXISTS
(SELECT M0070.[Contract No], M0070.[Contract Name], M0070.[Employee No], M0070.Forename, M0070.Surname, M0070.Branch, M0070.[Long Desc], M0070.[Emp Post Start Date], M0070.[Days per week],

It's combining data from 2 system Identified by E or L. The data is similar but not exact & I'm comparing it using the description. What I need Access to do is find the record that doesn't "zero-out". In the example above the record it should pull is the last one "Kroger $389.74". How to do this but I do have a query/report that will subtotal based on the LOC-RC field.
I have a table tbl_PolicyDetails with details of the policy the customers have with us.. In the tbl_PolicyDetails, I have two fields (these are the ones in question) called
"policyStarted" - Start Date of a Policy and
"policyPeriod" - Term of Policy Monthly/Annually/Quarterly
So in a Form view I just get the Next installment for the customer based on this information for display.. For example..
Mr Butters Stotch's policy started on 26/04/2013 and is paying Quarterly; the next (i.e. 2nd) installment would be on 26/07/2013..
Ms Wendy Testaburger's policy started on 07/04/2013 and is paying Monthly; the next (i,e. 3rd) installment would be on 07/06/2013..
This is not hard to get.. I have that sorted.. But the problem is, my manager wants to be able to specify two dates and search all policies that will be 'paying in' that Date range should be picked up..
So if the search range happens to be.. 01/07/2013 and 31/07/2013 Then Mr Butters Stotch's policy should be picked up, as his next installment falls on 26/07/2013.. Since this information is not stored, I cannot run a direct Query on this.. Also as the Installment number varies for each customer, I would not be able to just add 1 - Month or Quarter or Annum, and see if the date falls in that range..
I want to find unmatched records, where there is a condition. Specifically, which employees did not get a specific mail.
My employees are in this table:
tblEmployees
---------------
EmployeeID (PK)
FullName (text)
and sent mails are logged in tblMailsSent
tblMailsSent
--------
MailID (FK)
EmployeeID (FK)
so I want to find all the employees in tblEmployees whose EmployeeID may or may not be in tblMailsSent with some other MailID's but definitely not with the specific one I am looking for.
I find my own method for doing this rather clumsy, so do you happen to have a nice recipe?
I have a database that is used (partially) to enter appointments during a day. In the appointment column I've entered the date and time as dd-mmm-yyy-hh-nn-ss. I'm now trying to search for appointments entered on a specific day through a user input ([Enter Date] in the query criteria) Problem is, this only returns records where the time hasn't been entered and the time shows as 00:00:00.
I've tried CDate which gives me add/mmm/yyy return. if I try to search against that I get nil returns though. As a test I put DATE() in the criteria but it then says that it's an invalid foremat. I've also tried various machinations of "Like" and "Between" without success.
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<>"";
Are there any suggestions?
Thanks
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.
PIDM | regsYear | hc_Year
52 | 2009 | 1
52 | 2010 | 1
201 | 2007 | 1
201 | 2007 | 0
201 | 2007 | 0
201 | 2008 | 1
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.
Table: EVAP Database
Combo: Combo1
Filter Listbox: Filter1
Please note that I am self taught (90% of what I have learnt has been off these boards!). I did make this form with info I found on this forum.
I am having problems with a log in box for a database, the line of code is -
If Me.txtpassword.Value = DLookup("password", "customers", "[customerID] =" & Me.EbayName.Value) Then
This code is in a Form; "password" is the value in the table of "customers"; [customerID] is the primary key value I wish to remember; Me.EbayName.Value I assume is the value in the table that access is looking for.
Questions -
A) It is not looking up the value for [customerID] - what have I done wrong?
B) In the line of Me.EbayName.Value what does the 'Me.' part tell Access to do? I assume it's a pointer to it's own form? What part of the line do I need to change to make it point to another form (or table)?
C) When this is finished how do I get the program to remember the 'customerID' while the customer is fillling out other forms?

is there an easy way to find out in wich form a specific table is used.
I have an access application and i need to find out if every table definded is used in the application and in wich form.
I can open each form, see wich tables are used and make a list. But i have a lot of forms and there is the possibility to miss one.
I have a table of contracts. These contracts are renewed every year, and therefore many contracts have a version from the previous year, but some are new and have no predecessor. I want to write a query which lists all contracts on the table, together with a reference to any preceding contract with the same customer, or a null if there is none. For example, if the table fields are contract number, customer and year, and the table looks like this:
Contract Customer Year
271 Smith 2013
816 Brown 2013
101 Jones 2013
227 Smith 2012
564 Brown 2012
I want a query which returns:
Contract Customer Year Previously
271 Smith 2013 227
816 Brown 2013 564
101 Jones 2013 null
227 Smith 2012 null
564 Brown 2012 null
I am working on a DB for maintenance of medical records for use by medical mission groups in Central America. As a child's information is entered into the DB, I want to be able to display his growth progress percentile numerically instead of graphically as found on a standard CDC.gov weight vs height growth chart. The graph are nonlinear so I just can't use an expression.
I have the data for percentiles based on weight and height but I need to be able to find the CLOSEST value on this table to the child's observed values of height and weight.
How do I find the value on a table which is closest to a specified number?
