Hi
I have to make a query which deletes duplicate rows from my table. How I should start to make it? Can I do it whit one query or does this operation needs more queries? I know that DISTINCT works but how I can set it to DELETE operation?
I have try to use command DELETE DUPLICATES FROM Table; but this command deletes all rows from table why?
How do I delete duplicated records without having to make a new table? I would like the records deleted from the original table.

How I can delete all rows from my table whit on query? Also I want that when I delete rows from my table index and other settings will stay in table.
A SELECT works:
SELECT *
from mastertable
INNER JOIN secondarytable
ON mastertable.Identicalfield = secondarytable.Identicalfield
But none of these do:
DELETE
FROM mastertable
INNER JOIN secondarytable
ON mastertable.Identicalfield = secondarytable.Identicalfield
**Incorrect syntax near the keyword 'INNER'.**
DELETE
FROM mastertable JOIN secondarytable
ON (mastertable.Identicalfield = secondarytable.Identicalfield)
**Incorrect syntax near the keyword 'JOIN'.**
DELETE
FROM mastertable
WHERE (mastertable.Identicalfield = secondarytable.Identicalfield)
**The column prefix 'secondarytable' does not match with a table name or alias name used in the query.**
DELETE
FROM mastertable
WHERE IN (SELECT *
FROM secondarytable)
**Incorrect syntax near the keyword 'IN'.**
Can anyone help? This should be easy, shouldn't it?!
Thank you.

View 4 Replies View RelatedI need to append some rows into a table, before I add these rows i need to delete all of the old rows.
I can't use a Make Table query because I am updating a linked table in another database.
So how can I (automatically) delete all rows in that table before or during the append process.
Thanks

I have a list of projects and am creating a query that tells me their duration based on beginning and ending dates. These beginning and ending dates can be edited by the user, and frequently, there are multiple beginning dates. When I query the projects, instead of getting unique project numbers on the left hand side to create unique rows, I get many of the same projects with different start dates. I would like to use the FIRST start date only for every project and not have multiple rows with the same projects being counted multiple times.
Is there any way to delete the excess rows and keep the original row? I've read a lot about using DISTINCT and UNIQUE INDEX with SQL but it seems as though these are only available for tables and not queries. Bright ideas, anyone?
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.
Thanks in advance for your help...
Hi
I need to know if it is possible to create a delete query which will target particular fields in a row based on certain criteria in a seperate combo box(on same table).
The few ways that I have tried to do this have been unsuccesful so if anyone can shed some light on the subject it would be greatly appreciated.
Ok, folks. I'm confused.
I have a database I've created called 'EngLog'. This database is located on the server and everyone in my department accesses it to add their latest entries.
However, every now and then, for some unknown reason, a second database appears, titled 'EngLog1'. I don't know what creates this second database.
Any ideas?
This is not a FE,BE database, and also, i'm utilizing a .dll file called MouseHook.dll which I have previously heard about in this forum.
Thanks to all in advance. This problem poses a bit of a threat in that some folks here might accidentally be updating the wrong database.
Hello! I'm in the process of creating a report, but am running into a problem. I have a number of clients that include fields such as ID, last name, first name, address, etc. and then their account numbers. Each client has a number of different accounts. The problem is that each client's last name, etc is listed again for each different account they have, so the query results looks like this:
ID Last Name Account #
1 Smith 123-56
1 Smith 4458-66
2 Jones 523-63
2 Jones 4525
2 Jones 5236
3 Roberts 5225-56
4 Johnson 523-55
I want the names and client contact info to appear only once in the report and all of the account #s to show also. Any suggestions would be GREATLY appreciated!

From the data sample, I could like to find out the duplicated records. One of the queries is shown as below. But they cannot pick up these records. Any better way to find the duplicated records? Please help.
SELECT DISTINCTROW [C&B-will].[trading name], [C&B-will].[location street], [C&B-will].Field1, [C&B-will].[location no]
FROM [C&B-will]
WHERE ((([C&B-will].[trading name]) In (SELECT [trading name] FROM [C&B-will] As Tmp GROUP BY [trading name],[location street] HAVING Count(*)>1 And [location street] = [C&B-will].[location street])))

In a situation where I imported an excel file with so many columns and split them into two temp tables and they are linked using a key.
the data has a fixed part lets say
Field1....Field2.....Filed3.....Field4...then Field5.....Field6.....Field7....Field8 is the same data range as Field9...Field10...Field11...Field12. I would want to split this data into multiple rows like this
Field 1 Field2 Field3 Field4 Field5 Field6 Field7 Field8
Field 1 Field2 Field3 Field4 Field9 field10 field11 field12 and so own...
What is the best approach?
I am trying to assign teams to players. I have an import table with all of the players information listed. What I want to do is determine the count of players in a given city. For every 9 players I want to add a new record to the Team table and assign the team number (auto incremented for each team created). Then I want to add the players to the Players table with the Team Number that was created.
View 8 Replies View RelatedI'm trying to execute a query which is looking at data from 2 different tables and most of the data fields in the tables are the same. For instance table 1 has Dept, Res, Period_date, & Available Hrs and table 2 has Dept, Res, Period_date, Project & Forecast Hrs. The results I'm looking for are as follows:
Dept Res Period_date Project Forecast Hrs Available Hrs
11 A 11-02-07 123 XXXXX
11 A 11-02-07 456 XXXXX
11 A 11-02-07 789 XXXXX
11 A 11-02-07 012 XXXXX
11 A 11-02-07 XXXXX
But the "Available Hours" are duplicated in the preceeding 4 rows.
Thanks for any advice on this.
In access I queried my results and now I have to do this last step. I basically have an ID column and a tax fee column. I am trying to remove the duplicated ID numbers but if they are duplicated I need it to add up the tax fee column so I can have one ID with all the tax fees added up together instead of several different ones.
I tried doing the equivalent to a pivot table (works perfectly in excel) but when I tried doing it in access, it did not work.
I'd like to learn how to do them quickly and effectively in Access. One of those things seems like it would be an incredibly simple, intuitive operation, but it's not, at least not to me.Say I have some data that really should only be on one table, but it's currently on two tables in Access: "List Main" and "List September Adds." They both have the following fields: "Full Name" "Email" "Address" "City" "State" "ZIP" "Phone."
The first table is my main list of contacts. The second contains new info, consisting of 1. a few new contacts, and 2. updated info for a few of the contacts already in table "List Main."
I would simply like to put all the new contacts from "List September Adds" into my "List Main" table, and I'd also like to fill in a few missing e-mails in "List Main" with newly gathered e-mails for those contacts, info that is in my table "List September Adds."I'm sure there is built-in functionality to do something as basic as essentially turning two pages of the same spreadsheet into one. In fact, I know I could import data from an Excel file and have it "append" to a preexisting table if the fields are all the same.
However, I'd like to know how to do it when the tables are already in Access (without having to learn any SQL, mostly because I'm fairly certain I don't need to know SQL to do something like this). I've heard of Append and Update Queries and given their names, it sounds like they'd be useful, maybe with use of "Totals" and "Group By" to get rid of duplicates; however, I can't seem to get any of this to work right.
Mostly, when I think I am doing an Append correctly, it doesn't add new data at the bottom of a table; it just wipes out all the data that was there, and replaces it with data from the source. For instance, when I've been running an Append Query to get my "List September Adds" rows into my "Main List" table, what I end up with is only the "List September Adds" rows, and all the "Main List" rows gone.
I have a few input tables and I am trying to combine the fields from 2 tables into one query. How do I go about doing it without having the project amount (highlighted in red) being duplicated?

I am using Access 2010 32-bit on a Windows 7 64-bit platform.I have a database that I have imported existing data into. For the most part, I have eliminated duplicate entries in my Item Number field.
Obviously I have missed at least one (or possibly more) duplicates. When I try to create a NO DUPLICATES index, I am informed that there are duplicate entries.I am looking for a quick way to generate a list of values that are duplicated so I can address those and correct them.Item number field is a number field of type DOUBLE with 2 decimal places.
I have a main form titled "projects" with a subform titled "inventory". They are linked by two fields "project" and "fiscal year" with a one to many relationship. These fields are also the primary keys in the main form. I also have the referential integrity option activated.
Whenever data is entered in the subform inventory, it duplicates the main form and all the other subforms linked to the main form. (I have about 11 other subforms linked to the main form). So if I enter 2 records in the inventory tab, there will be 2 records for the same project and fiscal year in the subform and all the other linked subforms with the same data, so it is almost like it is seeing the inventory subform as the main form. I have tried deleting the duplicate record from the main form, then it deletes the 2nd entry of the subform. I have attached a pdf with a print screen of the 2 duplicate records with the same fiscal year and project name.
I have another form called Notes that has a similar relationship, but doesn't have this problem. I think it might have something to do with the conversion. I originally created the database with Access 97 and we are now using Access 2007. Am I missing something that needs to be done in Access 2007 to link the 2 forms, so I can enter records in the subform without duplications?
Also, the database is split so there is a back end and front end. I have all the tables and relationships set in the back end.
When I tried paste some data using front end to my database, Access showed error (can't create record because data would be duplicated). I thought it's impossible because it is autonumber field. So I checked it (manually). I did copy of my database and then for testing, I created record. I was shocked. Next record should has a value of "160" but Access gave "130" then showed an error "Can't create record because data will be duplicated". Of course after compact and repair everything is fine.
View 5 Replies View RelatedI'm new to Access. It is obviously a very powerful database program I've developed a data base of my agency's service purchases for a variety of clients. I have to generate a report totaling the monthly purchases and counting the number of unduplicated clients. We make multiple purchases for clients monthly. There must be a feature on this program that will sort through the client ID Numbers and count them (rejecting duplicates) in that one month or quarter or year. I've been exporting to excel, sorting by client ID and then counting each new ID number.

what I am trying to do is have a button that will copy that record to a history table then delete it off the the main table.
I cheated by using the wizard to get the code to delete the record but I am having troubles modifying the code to copy that record to the history table. Here is the code below. I have tried to insert code in several places but it just errors out.
