Delete Duplicate Records Based On Multiple Criteria
Sep 21, 2015
I need developing a new delete query criteria to add onto existing delete duplicate queries for deleting duplicate values. I need the new delete duplicate query to take precedent over the other two so that those values retained in the first query are kept retained after going through the second and third delete queries. Attached is a document laying out the request.
I would like to do a search for my records based on 2 different criterias. If found, the function should just return a boolean value so that I can act further based on the boolean value.
The reason I'm doing this is that I have 2 similar tables that contains EventID and AttendeeID and these 2 tables cannot have the same EventID and AttendeeID. So before I can allow a record to be inserted in the 1st table, it must check that there is no record in the 2nd table that has the same EventID and AttendeID. If there is, then i cannot allow the record to be inserted in the 1st table.
The same thing applies when I want to insert a record in the 2nd table. It must now check the first table.
Recordset.find seems to be only catering to 1 criteria, not 2.
I have a table that stores records by "return date". I would like to create a delete query that removes all records that fall outside of the date range entered on a specific form (frmMainMenu).
I can deleted the records that match the form criteria, however that is not what I need. The criteria used to delete the records was:
Between [Forms]![frmMainMenu]![from date] And [Forms]![frmMainMenu]![to date]
Let's say that the frmMainMenu contain the date range of 8/1/05 to 8/10/05, however the table contained data from 6/1/05-8/14/05, I would like for the query to delete all records that have a date 6/1/05-07/31/05 and 08/11/05-08/14/05.
Any assistance would be greatly appreciated. Thanks in advance for your help![/SIZE]
I am trying to create a delete query that, for a given person, deletes records in Table B that do not have a corresponding record in Table A.
Here are the relevant tables:
tblStates holds StateID, StateName, and RegionID (RegionID is a FK to tblRegions). tblPeopleStates is a junction table between tblPeople and tblStates.
It lists states assigned to people. It has 3 fields: PersonStateID, PersonID, StateID.
tblPeopleRegions is a junction table between tblPeople and tblRegions.
It lists regions assigned to people. It has 3 fields: PersonRegionID, PersonID, RegionID.
For a given PersonID, I need to delete records (i.e., states) in tblPeopleStates whose RegionID is *not* in tblPeopleRegions.
For example, pretend that tblStates shows that State IDs 1, 5, and 6 are all in Region ID (i.e., all have a RegionID = 10).
If Joe (PersonID = 200) has StateIDs 1, 5, and 6 in tblPeopleStates, but doesn't have a record for RegionID = 10 in tblPeopleRegions, I need to delete his three records in tblPeopleStates (i.e., the ones where StateID = 1, 5, and 6).
PersonID will be found on [Forms]![frmMain]![subform1].[Form]![subform2].Form]![PersonID]
I would like to create a query that will delete records that match several fields from another table. This is complicated by the fact that one of the fields will be in one of 3 columns.I have attached a test database (no real details), all Sheet2 entries need to be deleted from Sheet1.
What I need to do is delete records that have the same 'Surname' and 'DPS' value but also the same 'Line5' value from Sheet2 in 'Line3' or 'Line4' or 'Line5' in Sheet1.The 'Surname' and 'DPS' are no problem, it's the variable position of the third field. I think I could do it in three separate queries but it would definitely be better in one.
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.
I want to delete certain records based on the selected date. However, I come across with this is error - Run time error '3464' (Data type mismatch in criteria expression).This part is highlighted in yellow. I even used the debug.print to test out if the sql statement is executed properly.
Code: DoCmd.RunSQL DelSummarySQL
Here is my full code
Code: Private Sub cmd_Delete_Click() Dim DelSummarySQL As String Dim StartRange As Date
I need to count records based on multiple criteria from two different tables. I have two tables (i.e. "tblTasks" and "tblTaskHistory"). The tables have a one-to-many relationship based on the "TaskID" field. "tblTasks" has a field called "AssignedTo" and "tblTaskHistory" has a field called "TaskStatus". I need to know how many tasks have been "reopened", the "reopened" status is located in the "TaskStatus" field in "tblTaskHistory". I need this count against a unique listing of employees which can be found in the "AssignedTo" field in "tblTasks".
i am querying a single table that contains card numbers and corresponding transaction codes (amongst other things). a single card number can have multiple transaction codes.
i want to select all card numbers that have both 0100 and 0802 transaction codes.
if i use a select query with ="0100" Or "0802"as the criteria, it returns all card numbers that have either 0100 or 0802 transaction types. if i then change the query to crosstab and group by card number, it is clear that some cards have both transaction types.
when i try to change the criteria to ="0100" And "0802" it returns nothing at all.
i'm sure the solution is something really simple - any idea what i'm doing wrong?

Help please! I have a form (frmHalfTab) built on a table (tblHalfTab2) that has existing data in it. In the very near future, I will be uploading additional data to this table via excel cut and paste. What I want to do is search for and eliminate duplicate records that have duplicate data in TWO fields, (MemberNum) and (MBRDrug), so that if MemberNum is "10" and MBRDrug is "Zzz" for more than one record, the duplicated records need to be deleted, OR a check box needs to be checked automatically for all the identical records, the original and the duplicate(s). I wanted to put this behind a button, if possible.
Now, I have created a duplicate query that will find the duplicated records, but I'm not sure how to use it to get rid of the duplicated records or check the checkbox appropriately. Should I ditch this query and choose a different route, or am I on the right track? Thanks in advance for your help.:confused:
I have two tables that have duplicate order numbers. I would like to compare the first table with the second and then delete the records from the second that match.Can I set this up in a macro and run it every day?
I have a table that has 1335 records in, and columns names, Title, First Name, Surname, Address, Address2, Town/City, County, Postcode.I want to know how to write a SQL code, which will locate all the duplicates that match the First Name, Surname and Postcode and delete them, but keeping 1 copy of the duplicate.I have created a query to locate the duplicate records, and I have put the SQL code there. I tried changing this, however it would delete all the records, so I am not to sure what to try...
SELECT SurnameSearch.Title, SurnameSearch.[First Name], SurnameSearch.Surname, SurnameSearch.Address, SurnameSearch.Address2, SurnameSearch.[Town/City], SurnameSearch.County, SurnameSearch.Postcode FROM SurnameSearch WHERE (((SurnameSearch.[First Name]) In (SELECT [First Name] FROM [SurnameSearch] As Tmp GROUP BY [First Name],[Surname],[Postcode] HAVING Count(*)>1 And [Surname] = [SurnameSearch].[Surname] And [Postcode] = [SurnameSearch].[Postcode]))) ORDER BY SurnameSearch.[First Name], SurnameSearch.Surname, SurnameSearch.Postcode;
I want to find duplicate records based on FirstName and LastName and delete the duplicate. Also, I want to delete any records which have a blank FirstName and LastName.
I know this probably has been asked a 1000 times but I don't seem to be able to edit the uncommented VBA-codes I found online to work on my database.
I already ran a query that shows me the duplicate records of my original table. Now I m looking for a way to
a) delete all duplicate records (not just specific ones by using a criteria) and b) unite the unique records (result of a)) with the original ones that were not displayed with the "find-duplicates-query" ....
I'm wondering if it's possible to create a Query / Macro / VBA or whatever works, to detect the duplicate records in a table and delete them with the push of a command button. Or, even to do this automatically when the database opens using an AutoExec macro or something ?. I'd like for one copy of each record to be left intact in the table.
I'm using Access 2013. I want to check duplicate data. I have a form where from insert data into table but before insertion I want check multiple criteria with form. How can I do this

I am in the process of designing a sports database and have come across a problem that I can not seem to fix.
I have 3 tables that are linked, they are Customer, Program (this is the customers exercise program) and Health (the customers health records).
I have tried to set up a query that deletes a customer if a command button is clicked. This works find as long as the table I am deleting the data from is not linked to another table.
However when I try to delete a customer record it says that I can't as the data is linked and I have to delete the relationships first.
The only way I can think of doing this is to setup a query that deletes all the data in each table at the same time. I can not get this to work though.
Is this a problem that can be solved or will I have to change the way my relationships are set up?
Is there a way to select several rows of records in a datasheet view of a table and delete all of the selected records?
Every time I try to delete more than one record at a time, I get the following message: "The Micorsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time."
Then it will let me delete one record out of the selection.
I am the only one in that particular table at the time I am trying to delete the record.
