I have a question I've been trying to figure out with no luck. I have 2 fields, companyname and zip, these 2 fields may have duplicate values or they may be uniquei.e.
companyname zip
billybobs 68135
dilberts 68137
billybobs 68135
what I need to do is delete all of the duplicate records where both companyname and zip match. Is there a way I can do that with a query?
how or what function (DLookup) should I use to prevent duplicate records based on multiple fields? I want to look at data in three fields that can't match existing data in those three fields. It's ok if one or two of the fields match but not all three.
1. I have a database (see attached) with three tables all of them with the same fields. The first three are numbers (InCo_No, Proto_No, Year_No). Each of these fields (numbers) can be the same in the other table(eg. Year_No), but the combination of the three cannot be.
How can I prevent the entry of a duplicate combination of these three fields?
2. I want to have a form to fill the three tables separately, depending the values in the other fields.
I am creating a small database to house results of certain tests. Is there a function in access that allows me to add fields if a result is out of the specification required. In other words I still need to record the out of spec results but I also need more fields to appear for the next lot of results to be entered, for example.
When cooking a batch of product I need to test the pH at the 30 minute mark if the pH is too low I will continue cooking the product for another 30 minutes and then test the product again. The cook time is not a constant so I never know how many samples are required, therefore I don't know how many fields i would need in advanced.
I've put together a database for my company to track our archived files. When the files are archived, there are three important values pertaining to their location: a list number, a box number, and a barcode number. Each box has a barcode on it, so what I'd like to do is make it so that when any record has both a list and box number entered (since it is dependent on the list number to know which, for example, "Box 1" I'm entering information for), it would automatically insert the appropriate barcode number in the field. It would obviously need a seed for each barcode number to be entered before it would know which one to use, but that could either be based on the first unique entry, or entered another way. If anyone can help me do this, I'd really appreciate it. Also, if my description was insufficient or confusing, just let me know and I'll try to clear it up. Thanks!
Example: If I entered: List # Box # Barcode # 77 4 It might not know what the barcode is the first time. But once I had entered List # Box # Barcode # 77 4 366582 It would know what I was entering. Keeping in mind that I'm not showing the rest of the record, but just this end part, my next entry would look like: List # Box # Barcode # 77 4 366582 77 4 366582 ...the red representing that it would automatically fill that in, because it knows that if I'm talking about Box 4 in List 77, that must be the barcode.
Hello: Is there (simple) way that I can populate a field based on the values of two other fields? For example, in a list of new employees, if a new employee starts on Nov 30 and works in the Administration Department, his human resources contact is Mary. If a new employee starts on Nov 30 and works in Sales, his contact would be Fred. I hope this is clear! Many thanks!
I am having problems deleting various rows from an SQL table, the message coming up is "The row value(s) updated or deleted either do not make the row unique or they alter multiple rows (xxrows). Any Suggestions?
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 currently have a table in Access that contains over 2000 records, with a total of 20 fields (although some records do have null values for certain fields). Some of these records are nearly identical to one another and differ only in one or two fields. Others, however, are exact duplicates. Is there any way I can quickly go through the table and delete those records which are duplicates but, at the same time, ensure that those which are only similiar aren't deleted?
i have a data base with a primary key but some records have been added from a excel data base and now the data base has duplicate records with different primary keys. I do a Query looking for duplicate records based on a field not the the primary key. There are 315 out of 22000. I can sort the table and then manually delete the dups. The Query does not allow deleting records so finding the culprits in the full Data base is time consuming. How can i delete the duplicate records using a query? Is this function available hidden someplace in the guts of Access? Seems like this would be a frequent problem. The Microsoft forum addresses this problem and the only viable solution is the manual method, when they get to the Query method it looks like they just forgot what the subject was and tell you how to delete one record if you know what the criteria is. If two non Key fields are Identical then i want to delete one of the records.
I have an Access table with a number of records which refer to the same [InvoiceNo] but with data in different fields. Normally, my database works like this:
1)Import data from Excel File to tblMain in Access 2)Import data from Excel File to tblVendorLine in Access 3)Import data from Excel File to tblDunning in Access 4)Query is sorting from two first tables only records that refer to the third one (by InvoiceNo) 5)We have only items from tblDunning with data from other two tables to be send (mail to the vendor).
The point is, that when I have relation between those three tables, I receive only few records, but sometimes - for example - tblDunning refers to 5 records in tblMain and to 7 records in tblVendorLine - but there is only 4 records related between tblMain and tblVendorLine, so query shows me only two records. Ive made a query for each table (tblMain & tblVendorLine - relation with tblDunning). Then make one query of those two queries. It append data to new table tblDunnAll
So for example the table would look like this after
Vendor | InvoiceNo | CoCode | Status | Clearing_Date | PBk 100000 23333 GB11 Complete 23/12/2011 K 233332 121212 GB18 Complete 16/12/2011 K 134444 777777 GB12 Complete
how to go about merging the data for each name into one record. There are lots of very useful posting about using SQL to delete duplicate but I can't find a posting with addresses this issue.
I am working on form where the user selects either "IN" or "OUT" from a dropdown of field name "CheckOut" in Frm1.
If they select "OUT" they will in turn need to fill in 2 additional fields. When they change the value back from "OUT" to "IN",
I want those other fields to be cleared of data for just this record so next time they change back to "OUT" from "IN" those 2 additional fields are already blank.
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').
hello friends, I have written an insert query but sometime it does not work properly and leave some column blank. I want to write a query which should check for the blank columns and delete these records.thanks in advance
I have an unbound text box. I put a value, run an append query and append the value to the table. I want to know if I can delete the value in the text box automatically when the append query excutes. I am using a macro to run the append query.
How do I delete values in an array? I want to reuse that array but first I need to delete its values so I would start with Arr(0) rather than where I stopped off with the last loop at Arr(10) [assuming the last calculation inserted until Arr(9)]
Here is my code:
Set rst = CurrentDb.OpenRecordset( _ "Select * from dbo_ProductStructure where ChildProductNbr Like '*" & txtPartNumber & "*'") 'search associated fields with user input While rst.EOF = False ReDim Preserve Arr(i) Arr(i) = rst.Fields("ParentProductNbr") i = i + 1 rst.MoveNext
Im trying to delete values from a table based on the selected values of a listbox. The listbox values have a hidden column which related to the ID on the table to which I am trying to delete from (if that makes sense).
If I use the following code:
Code: Set ctl = Me.Results_listbox For Each varItem In ctl.ItemSelected CurrentDb.Execute "Delete * FROM Table1 WHERE Table1.ID = " & ctl.ItemData(varItem) Next varItem
I get an error stating Object doesn't support this property or method.
I have a form with a subform inside of it. On the subform I have created a field for a check box. I wish for the user to be able to click 1 or more check boxes in the subform and then click a delete button that removes all selected entries.
I have this code from a seperate post regarding this problem, but am not sure how to edit it to reflect what I need.
Sub DeleteRecordButton_Click()
'Delete the selected record dim strSQL as String strSQL = "DELETE * FROM mytable WHERE mytblID = " & Me![mySubForm].Form![mytblID]
I want to write an sql or vba code to delete records based on the month...For example I have a field called date which contains a date and I want to delete all Dates that are In April
Ive tried Delete from LinkTable Where month(Date) = 'April' Still Nothing
So I currently have a module which automatically backs up my database to a separate file everyday on open of my database.
If is it possible to create a function which will allow me to delete these backups after a certain amount of days (eg 30 days). They all have different file names based on the time that the backup was created but have the same extension of "*.accdb". I ask because it stores EVERY backup so the storage space required will soon build up unless manually deleting the files which is not what my client will want,
I have tried using the "Kill(pathname)" function but have had no luck yet!
If possible, I would like this to be done automatically either on open or on close of my database.
I am trying to delete a specific part from multiple BOMs in my database.
I have a table of the BOMs that I want to look in. I called this table PartTable. I also linked my database table SYSADM.REQUIREMENT which contains all the requirement parts for all of our BOMs.
So I am wanting to delete only part number 123XX from each of the BOMs in my PartTable.
I am able to select the records with:
Code: SELECT SYSADM_REQUIREMENT.* FROM SYSADM_REQUIREMENT INNER JOIN PartTable ON SYSADM_REQUIREMENT.WORKORDER_BASE_ID = PartTable.PART_ID WHERE (((SYSADM_REQUIREMENT.WORKORDER_TYPE)="M") AND ((SYSADM_REQUIREMENT.WORKORDER_BASE_ID)=[PartTable].[PART_ID]) AND ((SYSADM_REQUIREMENT.WORKORDER_LOT_ID)="0") AND ((SYSADM_REQUIREMENT.PART_ID)="123XX"));
Now how do I delete these same records.
I am getting error saying I have to select a table to delete from....
In my Access2000 db, I have a table, on which many different queries are based. Many forms are based on those queries. I want to delete some redundant fields from the table. I tried deleting one, but I found I could no longer open any of the associated queries and forms. Is there a simple way to delete table fields so that it doesn't stop me from opening associated queries and forms? (There are hundreds of them, and I have a lot of table fields that I want to delete).
