What To Use To Exclusively Compare Tables
Apr 6, 2006
I have company names in 2 tables to compare, but the data is slightly different but same companies. I want to know what companies are in one table but not in another. Here's an example:
Company Name in Table 1 = Virtual Micro
Company Name in Table 2 = Virtual Micro Technologies
Same company, but the spreadsheet I imported for Table 2 had the full name for the company, so therefore they are not compared the same and the query result shows them to be different.
Do they have to be exactly the same, or can I compare a certain number of characters or somehow use the "like" criteria filter?

I have small problem that I can't get access to edit my own database because the are constantly people using it. So is it possible to kick uses off my database so that I get exclusive to edit it?
Cheers

I have a VB6 project that connects to a Access database. I get a run time error when I try to copy the database as a backup - "You attempted to open a database that is already opened exclusively..."
I need to be able to copy this database while it is still open. How do I work around this?
Thanks Steven

I inherited a database that has two tables that are structured identical; one called tblcurrentdata and the other called tblpriordata. The user wants a report or export query that only shows records that has differences between prior weeks data and the current weeks data. The tables have 12 fields of data in a record per quote number. The user wants a query or report to identify the QuoteNum and any changes between the prior and current records. The table structures are as follows:
Code:
tblCurrentData/tblPriorData:
QuoteNum
CoName
State
ZipcodeNo
priorityColor
[code]...
QuoteNum 12345 field 5 (prioritycolor) changed from red in the prior week to green in the current week and field 7(POC) changed from Scott in the prior week to Jonson in the current week.QuoteNum 23451 did not have any changes therefore does not need to be listed in the query/report Unmatched query doesnt work because it does not compare multiple fields. I tried to structure a union query and use <> in each field but got too tedious and didnt give the expected results.

i have a form that uses a text box to search through my bookings, and when the user double clicks on the record in the listbox it loads that record in my main booking form..
this works fine. the problem is this..
i will search and find a record using the text filter.. i will double click on the record and it loads in the booking form.
i then close the booking form, and the search form is still open in the background..
if i then click on another record in the search form, i get this message..
runtime error 3008, the table bookings is already opened exclusively by another user... etc
below is the code in my search form, is there anyway it can be edited to make sure this doesnt happen.
Option Compare Database
Option Explicit
Private Sub QuickSearch_DblClick(Cancel As Integer)
DoCmd.OpenForm "newBOOKINGS", , , "[bookingid] = " & Me![QuickSearch].Column(0)
End Sub
Private Sub Search_Change()
Dim vSearchString As String
vSearchString = Search.Text
Search2.Value = vSearchString
Me.QuickSearch.Requery
End Sub
Private Sub QuickSearch_AfterUpdate()
DoCmd.Requery
Me.RecordsetClone.FindFirst "[bookingid] = '" & Me![QuickSearch] & "'"
If Not Me.RecordsetClone.NoMatch Then
Me.Bookmark = Me.RecordsetClone.Bookmark
Else
MsgBox "Could not locate [" & Me![QuickSearch] & "]"
End If
End Sub

Situation:
Have 2 Tables that contain the same information, one table was used during registration and had the Data changed
Question:
How do I pull a comparison query to match the registration table to the Main table and pull only the data that is different so I can update the main table with the new Information? :confused:

hello, i have checked out the forum for pevious Q's to this problem and found the below.
http://www.access-programmers.co.uk/forums/showthread.php?t=80692&highlight=compare+tables
only problem is thats its writen at a bit too technicle a level from where i am. i've done some investigation into the problem though.
found out i need to use the docmd.transferdatabase function to import the tables i need to compare into my current db.
my question is this. how does it import them, does it create new tables within the current db or is it put somewhere in temp memory for use only while db is open, not sure how it would work. ideally i would like it to import tables, do the table comparison then create a report of the differences or make a new table showing the differences, then it reverts back to how it was before i imported it. i.e. he current databse is unchanged except for maybe a new report or new table (the results).
thank you for any advice.
Neil

I have two tables that have the exact same structure. They both started with the same data, but each were changed separately. (Two copies of the same DB, editted separately). I need to review the data in each record and determine what has changed or if records have been added. Is there an easy way for me to do this? (Note: Each record does have a primary key)

Hello to all. The problem that I am faced with is that I have a master list with all the current users and an updated list with all the current users and new users. What I have been asked to do is to compare the information in these two tables and have been given the following steps.
1. If name (surname, first name) exists in both lists do nothing.
2. If name exists in Update list but not in Master list then insert a blank row in the Master list and add the following Update list fields to this row: ¨
3. If name does not exist in the Update list then remove the entire row that contains that name from the Master list.
4. If 2. condition ("name exists in Update list but not in Master list") below applies, then insert the blank row with some kind of marker (e.g. "*") in a column on the far left. This will allow us to distinguish between:
So that is what I have to do can someone please tell me what a quick to do this in access would be. Thanks

It need to compare two tables where the ID Number is not equal. Specifically I need to update new poducts in a table, but only those ID#s that are not already listed.
I know how to compare two feilds where they are not equal...
i.e. [New_Table].[ITEM_NUM]<>[Old_Table].[ITEM_NUM]
...but I'm currently limited by the join properties in the tables, since I'm comparing IDs and not the feilds. ANY IDEAS?

I work in retail and am trying to compare items that are on auto-replenishment for a particular location to items that the location should have in their retail assortment to make sure that all of their items are on auto-replenishment. I need to also perform the comparison backwards to find out if any items are on auto-replenishment that should not be because they are not carried in the location's retail assortment.
I have attached a file below that shows the files I am working with. The first tab "items on replen" show the item # (in text and general formats) along with the location number, the min and the max. The 2nd tab "POG's by Center" show the retail planograms assigned to each center. The location# is at the top of the file and the planogram numbers fall below each location #. The 3rd tab shows the items on each planogram. The first thing I need to do is convert the planogram # into items on each planogram in each center. This is what I would need to use to compare to the items on replen.

Hi,
I'm trying to compare partial text records across two tables.
The first table simply has a description, such as:
DescriptionHammer
Bone Saw
Power Saw
The second table is a list of terms and a category, such as:
Term, Category
Hammer, 1
Saw, 2
I'm looking to build a query will compare the two and assign each description a category based on the partial match. It seems like this should be fairly easy to do, but I'm struggling to find anything to point down that path.
Any ideas?

I have an access application that I've developed and given to people and now i'd like to update it. I have a "master" database that I use for development and I would like to compare the users databases to this one and apply any changes that I've made to the database schema without having to remember all the new fields, tables and everything else I've added.

I would like to compare 2 tables by looking only at the names of the fields, data types and their properties (e.g. required yes/no). I am searching for a method to export this information to another table and then make comparison. Maybe sth. similar to “documenter” or another tool. Some ideas would very much appreciated. Thanks Bartek.

Been trying to crack this one for a while hoping someone on here might be able to help me. ;)
I have a table with a list of required software and a table with a list of computers and the software installed software. I made a query that displays the machines with the required installed. My problem is if a machine has more than required then it does not display the record. If it needs Office, Photoshop but has office, Photoshop and quark installed then it does not display that machine.
This should be quite a simple thing, I have played with Like, NOT, Where and others but with no luck...
Any help would be greatly appreciated.

2. When the data gets copied in Access table then write So VBA code that will check if the data in field LitRef in table "tblSummary" is present in field "Reference" of Access table "tblliterature" . if its present then check in the tblSummary , which corresponding fields out of "Withdrawn","Obsolete" and "Updated" stores "Y" .
