Modules & VBA :: Query To Compare Values To Show All Records Where Form Combo Value Is Selected

May 1, 2014

I am building a tracking database where we would be able to track information which field are null data and report them to our Administration to fill the null data. For this I have created a form name "Search" and I have a combo box control on that form which is bound to "Table = employee" and its ROW SOURCE TYPE="Field List", I would like to able to query records where the selected value in this combo box is null through out the table.

For example if I select "Telephone" from this combo box dropdown, I would like the query to show all the records where the "Telephone" is null, how to set the criteria in query to take the combo box value as "Field Name" and then compare it with the Field/Column in the table and show the null values.

Forms :: Search And Compare Value From Three Tables In A Form

Oct 18, 2014

I have three tables: Table A, Table B and Table C

Fields of Table A: Truck No, Capacity
Fields of Table B: Consignee ID, Capacity A, Capacity B and
Capacity C
Fields of Table C: Consignee ID, Final Rate

Input form is based on Table C:

1-I select Truck No using a combo box and it shows the Capacity from Table A using DLookup.
2- I enter the id no. in the field of Consignee ID and it returns the values of Capacity A, Capacity B and Capacity C using DLookup from Table B.

So I have to write manually one final rate in the field of Final Rate in the form.So I want:When I enter id no. in the field of Consignee ID, it matches with the Capacity in Table A and shows the matched result only in the field of Final Rate of Table C.

Tables :: Compare Field Data In Two Tables

Jul 10, 2015

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.

Compare Tables From Diff Db's

May 5, 2005

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.

Compare Contents Of Two Tables

Oct 5, 2007

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)

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?

How To Compare The Elements Of Two Tables

Aug 25, 2004

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

Compare 2 Tables Where NOT EQUAL &lt;&gt;

Feb 7, 2006

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?

Using Access To Compare Tables

Apr 3, 2014

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.

Partial Text Compare Across Two Tables

Jul 20, 2007

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?

Show Calculations In Tables That Are Entered In Form View

Jul 12, 2007

I would like my table to show the result of a calculations (or a formula). I surmise that you can not have a column cell calculate data, however if I can do this in the Form View and on a Report - can it just SHOW on the Table so I do not have to keep switching back and forth to see the information.

I am new to Access and think the forum will be a big help to me.
Thanks

Compare Data In Two Tables, With Multiple Conditions…..

Aug 25, 2005

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.

Access 2010 - Getting Form To Show Update Data To A Table When Two Tables Referenced

Jun 27, 2012

I have a form with two tables referenced. I am using the form only to update one of the tables. I am using the other table to pull a reference field. When I add my second table using the query builder, it makes it to where I can't edit/add in my form. I assume its because of the SQL insert statement, but I don't see this statement and can't find where it is to edit it. How to have the form only update one of the tables, while just using the second table as a reference for a field?
