Tables :: Master Database - Several Tables With Two Reference Points
Jul 4, 2013
I have broken up by master database, table, into several tables. They all share the same ID values since they came from the master table. So each table that I split off has a unique, matching, identifier, ID, in both the master table and the new table. Plus a previous matching identifier listed immediately below.
Example: Permit the master or main table and Builder a supporting table. There are five tables that I split off and all have an identifier similar to the two listed below.
Permit->ID
Permit->BLD
Builder->ID
Builder->BLD
All my tables have the same ID. But each table also has a identification numbers such as builder BLD, Subdivision SB and inspector INS>
Permit has the BLD, SB and INS
Builder has only one occurrence for each builder in the Permit table. As in the past it was identified by BLD number and now also ID. the use of BLD is from when I used visual dBase. The big difference here is that I have two ways to identify one is ID any other is by BLD, etc. My first thought is to identified by the BLD. I don't know why, but I guess I fear using a single "ID" to identify my various split off tables unique value or BLD.

I want the user to be able to see the source/reference of (many of) the different data points in my database, so I need to store sources/references in the database itself. I want to have all references in one single/common table (list of references). Each reference may be the source of many data points, in different columns in a given table, and in different tables. Is this possible, and can it be done in an elegant way?

I have database for each location. Every location will update some information in the databases and send it back to me. In those location based databases, information will be stored in one table called "consolidate_input". I will store these databases in one specific directory and then I want to accommodate the data of "consolidate_input" into one master database having the same identical table in the database.

I have a problem when storing a calculated field with two decimal points. If I set the field to double, fixed, 2 decimal points. For the field it will show the calculations as:
21.364 as 21.36
21.563 as 21.56
21.272 as 21.27
Which is how I want it to be, however when I run a summary of the field rather than showing 64.19 it calculates as 64.20, I know that this is the correct figure but is there any way I can get it to show me the 64.19?

Hello,
I am putting together a database for a charity and am having some problems. At present I am working seven days a week and my time for research is so limited that I can only ask here for advice since I have neither the time nor resources to seek it out myself.
We do mail shots to various trusts and businesses to appeal for donations. At present we have two large, bloated MS Works Databases (one for Trusts and one for businesses) that contain names, addresses and so on. I have taken on the task to make our mail shoots more efficient. My vision is that the majority of time should be spent searching out new business/trusts and organising events while actually doing the mail shoots should basically be done at the touch of a button (it won't quite work like that, but previously the actual mailshots took up about 80% of the time. I want to drive that number down)
Having no Access experiance whatsoever I set about creating a Database with twelve tables, one for each month. Each month would contain a list of places that we would "hit"
I then came across a problem. When I am searching out new addresses I would have to cross reference them on 12 different tables. This struck me as being impractical but at the time of creation I didn't have the foresight to create a masterlist. Although I do have the list on my Works DB, it would be useless as time passed since no more entries would be inputted on there.
I was hoping someone could tell me how I can put together a masterlist using the data I already have and maybe if possible setup the 12 tables in such a way that by inputting an entry on one of them will automatically crossover the name of the business to the masterlist without me having to enter it twice.
I realise this may sound confusing, and if i had more time I would research the answer myself but I am stretched to the limit and know too little about this application. I did try to take on a Lyndia (sp?) course but again I just don't have the time. If you have any questions, I will check back later to answer them.
I am using Access 2002 (but my DB is in Access 2000 format - so it says)
Thanks kindly.

I'm working on recreating my church's records in access and was originally wanting to take people from the Visitors table and automatically move the to the Members Table (and same with Deceased & Moved), but after some searching found that's not really do able. So now my question is, can I have a master table that has everybody (visitors/members/deceased/moved) and then split that into different tables while keeping the main table (that way I can go into the main table and reassign the person)?

I have a database with 7 related tables. Now the main table is called STUDENT. I am essentially creating a report card system and have broken down each part of the report into another table. Now to make it easy for teachers I have created a form which they can search for a class and in a datasheet all the students plus their ID numbers come up along with the spaces for them to enter their grades etc.
The problem I have is this. How can I get access to look for any updates from the STUDENT table and apply this to the other tables as it would not do this automatically, even though they are linked one-many I have copied the data from the main STUDENT table into each other table just so theres a reference for a teacher. Is there any magic button or something that I can make to do this so all extra student names and IDs are added to all other tables?

I have recently acquired an Assistant Management position in a small restaurant and I have been given the task of creating a database of all of our Recipes with a master list of ingredients. I can easily set this up in Xcel but it is very messy and time consuming to say the least.
I would love to be able to create a master list of ingredients (1-X) With their unit of measurement (Pound, Gallon, Etc) as well as their unit price (pound of bacon= 5.00)
Now the recipes would be set up with the (ingredient-amount of ingredient-cost of amount of ingredient)
I would like to start a new recipe by opening a table, typing in a number that corresponds with an ingredient on the master table and those fields be filled in other than the amount of ingredient. Also by changing the price of an ingredient would automatically update on the recipes.
my boss wants to know how much each recipe cost as well as keep them updated when the price of ingredients change.

I was wondering if it was possible to have a master table where say 10 of my regulatory tables and their data once inputted from the forms will appear there? Is this possible? Because right now, each of my regulatory tables has a form where the data is inputted and appears within said table.
All these tables are separate, obviously. I want to consolidate all the information into one spot, is this a possibility within access?

I am using Access 2007 and have inherited a database. It has linked tables of Excel spreadsheets that are information extracted from our main system. The user wants developing a much faster and customized approach to billing the customer based on payroll related information.
There is a table of payroll billing transactions and it has the following record lay-out,
job_num, employee number, employee name, union group, rank, regular hours, overtime hours, other hours, trans_date, seq_num
6430, 2301, john doe, 1, F, 8.0, 0.0, 0.0, 12/01/2012, 254333
On December 1st John Doe worked 8.0 regular hours as a pipefitter foreman on job number 6430 and this is record (sequence) number 254333.
There is another table that defines the union group. I am not concerned with this information at this time. The seq_num is a sequentially and uniquely assigned number given to each billing record in the main system.
There is also a Rate Master table and it has the following record layout,
job_num, union group, rank, regular_billing_rate, overtime_billing_rate, other_billing_rate
I am struggling as to how to relate these two tables so that I can develop some queries from it.

I have a database with two tables. tbl_job_information contains all the contracts info etc. tbl_data contains all the relevant work data. The first table is restricted to certain personnel, whereas anyone has access to the second table. Both tables have a column called 'job no', in the first table it is a primary key, in the second just a field. I would like to make it impossible in the second table to change the data in the 'job no' column to anything that is not in the same column in the first table. It this possible within the tables themselves, or would I have to do it via coding and forms?

I have two tables, Table 1 and Table 2 and two related forms, Frm1 and Frm2. I want to be able to update the data on Table1 from Frm2, that is, if I change the data on Frm2, the corresponding fields in Table1 will update to the same data. I know that if both tables are open I can reference the fields on Frm1 and Frm2 with an IF statement: If Active = True And Forms!Frm1a.DoNotchange = False Then..And I know on the update query I can reference a control on a form by Forms!Formname.Control. Wll works fine.What I would like to know is can I reference a table field in the same way. For example, I have tried to use the IF Statement If Active = True And Tables!Table1.DoNotchange = False Then..Is there a way to reference the Table instead of the Form in both the VBA and the query? The problem seems to be that I have the two bound controls [Active] on Frm2 and [DoNotChange] on Frm1. (Which I need).

I'm new to access and need to modify an existing database to get a report I want to create. I'm an Excel user and could accomplish what I want to do in seconds using Excel's Lookup functions, so I'm trying to do the same with Access Dlookup.
I have two tables in my database that tracks components in a hardware product. The first table is just a list of hardware units shipped. The second table is a list of various components (and versions thereof) used in each unit. The two tables are linked by a UNIT_ID field. I need to create a report showing each unit and what the various versions of the components are. My difficulty is that the component table is does not have a dedicated field for each component and each unit can be comprised of a different quantity of components. So the tables look something like this:
UNITS TABLE:
ID Customer
1 Joe
2 Bob
3 Bill
COMPONENTS TABLE:
ID Component Revision
1 Main Board A
1 Blue Board B
2 Main Board B
2 Blue Board B
3 Main Board A
3 Red Board C
I want to produce a report that looks like
ID Customer Main Board Blue Board Red Board
1 Joe A B --
2 Bob B B --
3 Bill A -- C
I setup queries to get revisions of each Board and am trying to compile into the full report, but can't figure it out. Right now I'm trying to use Dlookup to lookup data from one of the queries and insert into a larger table. I can lookup a single value fine, but can't figure out how to get Dlookup to give me the Blue Board & Red Board values for each of the system ID numbers in a master query (which would be a snap in Excel).

use an account reference from one field in a table on a second table and add a number after it... e.g.
Table 1 Table 2
PEFA PEFA/001
PEFA PEFA/002
PEFA PEFA/003
PEFA PEFA/004
and so on...

Basically I have this formula in excel and i'm trying to recreate it in access but i can't quite figure it out.
****a***********b**********c*********d*********e** ******f
3**Car***Cost Center****start****combining*****end*****miles
4**001*****aaa********021****=(A4&" "&C4)***030
5**002*****bbb********030****=(A5&" "&C5)***035
6**002*****aaa********035****=(A6&" "&C6)***040
f4: =IF(COUNTIF($D4:$D600,D4)=0,(E4-C4),(E4-C4)/COUNTIF($D4:$D600,D4))
f5: =IF(COUNTIF($D5:$D601,D5)=0,(E5-C5),(E5-C5)/COUNTIF($D5:$D601,D5))
f6: =IF(COUNTIF($D5:$D601,D5)=0,(E5-C5),(E5-C5)/COUNTIF($D5:$D601,D5))
So basically: If a car is using multiple cost centers for a trip it divides the total mileage among the cost center for said trip provided that the user enters the same start and end mileage on all the cost centers used. And if it doesn't have multiple cost centers it provides the appropriate amount.
=IF(COUNTIF($D4:$D600,D4)
=IF(COUNTIF($D4:$D600,D5)
=IF(COUNTIF($D4:$D600,D6)
and so on
Any way to reference a column in access while referencing a specific point within that column.

I have 2 identical database in terms of structure but it differs in data.
Basically I would like to import data from subDatabase to mainDatabase and ensuring that there are no duplicate records.
I have used the "link to datasource method" through importing the tables to have the "updating" function.
However, this method also means that the records in mainDatabase are also imported over to subDatabase which I do not want.
Is there a method to ensure that the records are shared/update one way only? (i.e. import from subDatabase to mainDatabase and not main to sub?)

I am splitting a database and have created the Back end already. When I create the front end and link to the tables on the back end... The front end does not link to all the tables in the back end. The list that comes up when creating the linkings does not show all the tables in the back end. What would cause this?

I have three tables that contain different columns but linked by a primary column call Name. I want to create a table where all these different columns in the three tables join to form a master table which can be updated regularly either through the master table or the smaller tables. The master table also has the primary column as Name.
If I update the master table with records, it should update the respective linked table and vice versa. I also want to link these tables to my SharePoint site.
Note: except the Name column, none of these tables have any other columns in common How do I go about this?

looking for a way to export the list of table names, table types & if they are linked (e.g. tbl Sales Linked .dbf or tbl Staff linked to excel) from a database - this has to be done for about 300 databases.
in an individual db, I have a make table query off of the table MSysObjects to get the data. The Database field tells me where the source of the linked table resides & the ForeignName field gives me an idea of the format of the data source (e.g. dbf or excel). I could manually import that query into each db, run it to get the table names, then copy & paste..

I have a master table with about 40 fields. In addition, I created eight child tables with read only datasheet views of limited fields from the master table. The child table views are based on certain critera in the master table and are being refreshed by using delete and append queries tied to the On Current property of a form. By double-clicking a specific child record, a form is opened to allow editing of the master record. Also, I am using Referential Integrity and Cascade Update Related Fields to update the child table when a change is made to the master. However, I do not know how to add a record to one or more child tables when a record is added to the master table. The new child record would have to be based on the same critera that the append queries use so it gets added to the correct child table or tables.
