Normalize My Table - Track Price Levels
Aug 22, 2005
i would like to have a table where i can track price changes, however i don't want this to based on an inventory order.
i have a table which has the amount of hours to be charged. i then have another table which has the price per hour charged. the price keeps on changing. both tables have the date. tableHours has the date of occurance and TablePrice has the date when the price was last updated.
i need to know how to structure the TablePrice. currently it is set as BillableHourType, Rate, EffectiveDate. If this is correct, i don't know how to run a query.
i need to multiply Hour*Price, criteria: Effective Date must be most recent date as of Date of Occurance.
All Help will be appreciated.
I posted this post on the Microsoft site and i got no good responses, i am new to this site, but if it is a problem of reposting, please let me know. i will not do it again.
thanks,
sam

Im trying to create a database so I can Monitor grocery items from different supermarkets in my area.
I have been doing this on Excel for a while now, and its time to do it properly.
The only issue I would have is when I enter data.
I want to be able to track the price changes on items. I have my own.
So for example. Each time i enter the price of an item, I want a time stamp with it. (being the date when i entered the item, should be automatic)...

I have data that I would like to use within another system. In order for this information to work as desired I will have to "de-normalize" my tables into a single record set.
Here is the issue, I have 40k+ records that have the majority of the data I need in a single table. I have directory path links to the photos related back to the primary key.
I need to merge these into a single line of information.
Example:(this is simply an example and not the true layout)
Tbl1
PKEY De1 De2 De3
123 North 15 Blue
124 North 28 Green
Tbl2
PKEY Path PhotoName
123 M:Photo 123(a).jpg
123 M:Photo 123(b).jpg
123 M:Photo 123(c).jpg
124 M:Photo 124(a).jpg
124 M:Photo 124(b).jpg
124 M:Photo 124(c).jpg
124 M:Photo 124(d).jpg
The desired end result would look like
PKEY De1 De2 De3 Photo1 Photo2
123 North 15 Blue M:Photo123(a).jpg M:123(b).jpg
...and so on until all photos for the record have been listed out.
Any suggestions? If a search topic similar to my issue could be recommended I would appreciate it greatly.

I am working from an existing database which is just two table. The main table has a massive amount of redundancy and duplication and needs splitting into, at first glance, 5 tables.
After I have run my various make table queries and added a Primary Key and FK field to the new tables how do I populate the FK with the Parent PK.
I thought I could simply add all the fields from the new table and then create an adhoc join in an update query to populate the PK to the FK. When I do this however I get "You are about to update 0 records"
I have tried the table analyzer but it doesn't give the correct options to split the table the way I need.

Just wondering if I'm missing an SQL trick for normalizing this data I inherited from an Excel spreadsheet.
Current data:
Code:
Case | Insp1 | Insp2 | Insp3 | Insp4 | Insp5 | Rnsp1 | Rnsp2 | Rnsp3 | Rnsp4 | Rnsp5
---------------------------------------------------------------------------------
1234 WEEDS TRASH CAR <null> <null> WEEDS CAR <null> <null> <null>
1235 TRASH <null> <null> <null> <null> TRASH <null> <null> <null> <null>
Normalized table:
Code:
Case | Violation | InspectionType
-----------------------------------
1234 WEEDS Initial
1234 TRASH Initial
1234 CAR Initial
1234 WEEDS Reinspect
1234 CAR Reinspect
1235 TRASH Initial
1235 TRASH Reinspect
Right now I'm having to do it with ten different queries (each with its own query behind it to massage the original data), one for each Excel field, and checking for blank entries before appending. And there's going to be about 50 Excel tabs to gather up... anything I'm missing besides the basic slog?

I have been tasked with producing a Service Catalogue - essentially, a list of services offered by IT to our business customers.
The Catalogue is a repository of information related to the service - such as, Service Info, Business Info, Server names and location, DB info, Batch and Online times, Network Info (and the list goes on).
Obviously, these are high-level categories. Within each of these (for example. Business Info) there is more granular info such as, Business Owner, Supported Business Area (there can be more than one) and Business Criticality.
Given the data and the fact that some category items may have one or many values for any given field (DB names for example), is this something worthy of a DB?
I have tossed this around in my head and I can't get away from the notion that I will require multiple tables with untold fields (yikes - scary thought!)
I have attached a rough DB but before I put any more time and effort into it, I want to know if I am on the right track.

I am using a table a user created which is like:
Member ID (key field)
Visit Date
Dept 1
Expense Code1 (combo box E through I)
Dept 2
Expense Code2
This goes on through Department 20.
Now they want to know how many E's for one month. I am stumped on how to normalize this or if it is even possible! I thought maybe there is a way to search the table as if it were a spreadsheet doing a "countif" function??
Any replies much appreciated!

I have a table called Books, in that table there is 4 columns ChapterName, Auther, ITEM, Price.
Each book has a item number, and each book has a few records with the same data, just the first column is different where its the ChapterName, each book has a price, but only once, meaning in the first record of each book it will be a price in the column price
Now I want a Query where i can get which book dont have a price at all, and which book has more than once a price, how can i do that?

Ok, having a very beginer problem here (I Think)
Here are my relevant tables:
I have a table called Items which has itemCode (primary key), itemDescription, and price.
I have a table called bidItems which has bidCode (primary key), itemCode (primarykey), and some other info
I have a table called Bids witch has a bidCode (primary key), and a bidDescription
Here is a form that I use to enter data into these tables and (want) to view prices and totals:
I made a form based on the Bid table with a continuose subform based on the bidItems table, with combo boxes that lets you select Items by itemDescription (then it stores itemCode automatically with the correct bidCode)
What I can't figure out how to do is get each item's price to automatically display on the form (remember price is in Items table, not bidItems). I've tried a number of things that havn't worked out.... any ideas. Then, ideally I would like the form to display the total of all the item prices. (if you have a pointer on that as well it would be much appreciated)
Thanks

Hey guys,
OK, your gonna have to bare with me a little bit as its hard to explain and if any VB is given please add a few annotations as I have to explain everything i do in a report (doest have to be too detailed, just to make the code understandable :) ) and if it needs better clarification feel free to ask :), but basically, I have the following relationship set up:
http://img512.imageshack.us/img512/3246/relationnshipswd9.jpg
At the moment, because of the way it is set up, I cannot create a record in the transactions table unless an income record is given for it (because tb_income (one) to tbl_transactions (many)) but the way I want to work is as follows:
If you have a look at the tables tbl_transactions and tbl_income and their link. The way I want the system to work is when a new transaction is made, a new income record in the "tbl_income" table would be made with the date (in tbl_income) being the date at that particular time and all transactions created on the same date would all go in the subdatasheet for that one record created for that date; and if another transaction is made on an alternate date (say 00:00am of the next day) another income record would be created automatically with the date being of that particular day etc.
My other problem im facing is that everytime there is a transaction created, I want the stock level(s) field of products in that particular transaction to be decreased by the quantity purchased of that product but i have no idea how to do so
Any help?
Thanks a lot in advance!
Daniel

I am having trouble calculating a field in a table and on a form.
I have the following Tables
CUSTOMER: Customer No, Name, Address, City, State, Zip, Discount, Phone, Fax, Contact Person.
ORDER: Customer No, Order No, Order-Date, Delivery-Date.
ORDER LINE: Order No, Product No, Quantity Ordered,
line-item-cost
PRODUCT: Product No, Description, Price, Product Image.
I need to calculate the line-item cost and need it to update every time the user enters a new Quantity ordered on the ORDER LINE form.
I know its (Quantity Ordered*Price)-(Price*Discount) and I did this is a query and it worked but I need it to update in the form and update in the table not the query. I have tried everything (Macros, Queries, and Formulas) and I just can not get it to work.
Does anyone know how to do this?
Thanks

Im working in MS Access 2003.Im creating an audit trail for users actions in a form, to monitor and keep track of what fields were updated/entered/removed from the database, these actions are essentially done from command buttons (and the audit trail, is coded on the button click)
However, I have a few search screens, that return a subform listing results. These datasheets returned are effectivly like opening the raw table and hence are editable, (permission to change is granted as they are admin only searches, yes, they can change the raw table)
How can I track the change to a raw table field, ie, if someone updates the field SURNAME from 'Smth' to 'Smith', is there something that triggers this (obviously if it was in an interface textbox, you could audit this) is their a field change. The only way i can suggest it make a recordset of the intial results, then compare that to the results in the table as they leve and compare the two.

When I use the code given to me the program complies but it does not show the new total price in the for box
dim a, b, c
a = me.[your quantity textbox]
b = me.[your price textbox]
c = a*b
me.[your total textbox] = c
This is the code I used and my total box is called (line_item_cost)
is there anything that I am doing wrong?

I have to design a price list table which is currently done in Excel.
The table looks like this :
[Headers]
Product Group | Layers | (this are quantity bands) 0-100 | 101-500 | 501-1000| etc
Test1 | 2 | £10(normal) £9(special)
The quantity band currently is fixed to 5 bands but would need to be flexible. There are also 2 prices for each of the quantity band (normal/special)
At the moment my table design looks like this:
ID
fkSupplierID
fkProductGroupID
txtLayers (value list)
intMinQty
intMaxQty
curNormalPrice
curSpecialPrice
This works quite well with the query to return price based on product group, layer and order qty. However I am not very sure if this is the best way to design this. I am just thinking about maintenance - for example when the supplier puts in a price change or when the quantity band changes. The current format (quantity band) is based on a major supplier but in the future we would like to adopt this for any supplier.

I am re-designing a database for 2008 and trying to eliminate my Make Table Queries as I have found them to be somewhat consistant over the last year, particularily when the users do not open the database on a given date. It seems there should be a simple way to accomplish what I want but I am struggling and need some assistance.
I have attached a sample of a few tables from my database, Open Cases, Closed Cases, and Date Today. The Open and Closed tables change daily due to a Corporate download and contain several date fields which have different meanings. As new cases are opened, they go on the open table, and as an open case is closed, it moves to the closed table. The tbl_Date Today is pre-populated with dates of working days only. I have a query called "Count Of Shelf Comb" that counts the number of open cases as of today, which in truth is for all activity through the previous business day. What I want is to have a query that will show each date on the tbl_date today as well has what the total count of open cases was for that date......a permanent history of the amounts.
How can I accomplish this without using a "Make Table Query".

We have a db to register permits that count for one calendar year. This since 2012. For next year, permits must be renewed. How can we keep track of all permits per year per user in the same table ? We would like to produce annual statistics as well ? Easy solution would have been to copy the existing table for the year 2012 and paste as a new table for year 2013 but we don't know yet who will renew his permit ...

I am working with a database that I downloaded and am trying to modify to fit my needs.
This is an inventory database. The products table contains a description and pricing. I want the description and pricing to populate in the Purchase Order form, so I added Dlookup fields in the Purchase Order form. I was happy.
However, the pricing information is not populating to my Inventory Transactions Table from the Purchase Order form by way of this Dlookup feature, and therefore will not show on my report, and in turn does not show in my Total of my Purchase Order report.
As a work around, I tried creating a calculation in the purchase order report, of =[UnitsOrdered]*[Products.UnitPrice], and the pricing totals show fine on my report, but the subtotal doesn't work.
I was unable to upload my file...so a few notes of info...
There are no queries set up in the database for this report.
I had tried a sorting grouping thing (in the Report) by Subtotal, but now can't get rid of it.
When I show the field list for the report, across the top of the window reads:
SELECT DISTINCTROW Employees.*, Products.*, [Inventory Transactions].*, [Purchase ORders].*, Suppliers.*, nz([Inventory Transact
Looks like it runs out of space
I am trying to attach a couple of images to support my comments.
Since this issue crosses both reports and forms (and tables!), I am not sure where to properly post. The end result I am looking for is on my report.
I am using Access 2003...

505 - after 5 numbers are placed
Will be added for next hire
My goal: to place employee numbers into new employee field "EMP_ID_DDSK" (table 1), Numbers will come from (from "Res_Numbers" field (table 2)
Example: If field "Prev_Emp_ID" = false
Get the next number in line from table 2 "Res_Number" and place it in table 1 field "EMP_ID_DDSK".
Example: if "Prev_Emp_ID" = false for 5 new employees. Take the next set of numbers and place into field "EMP_ID_DDSK".

I have a performance evaluation db in MSA 2003 I am about done with. I had asked a question and got a helpful response. However, the response mentioned normalizing so I hit up google for more info. My db is not normalized, but after reading several sites, I don't see why I need to normalize it. The sites also said there are not a lot od reason not to normalize. I can't believe I just stumbled onto one. I have fields in my table that need to be scored on a 1-5 scale. I can see making a separate table for scores. However, the list of questions never grows or shrinks. It's a standard format that asks the same 20 or so question every time. Is there a reason to split the table into multiple tables? If so, would it be the scores vs. employee info tables? TIA for your assistance!

Hello I have a question.
I work for a company that had someone set up an Access database that generates work orders.
That person created a single LARGE table. 107 fields in the table. over 3000 records created so far.
Should I bother to try and normalize it?
Can it be Normalized?
Is it a pain?
Or should I just start over and create a new database. I thought about doing this but don't know if I can copy the old information into the new one.
Thanks for any advice you can offer.

I have a table -
TableID
PartNum
PartName
InstallTime_Shop
InstallTime_Site
InstallTime_Cadd
InstallTime_Testing
InstallTime Is a set amount of estimated time per part. This Value would be used to estimate time needed to install a part.
Should InstallTime_ be in its own table?
If it is in it own table would it one to one?

This has been a nightmare all around. Because I can't get 40 licenses for Access I'm stuck doing transferspreadsheets every day, which has worked out mostly, but I'm reaching the absolute limits of my knowledge. I can't even think straight and need help with a solution.
Here is the table data I'm bringing in (in a simple way)
Editor Client ResearchHits HitsSent AltEditor Pruned Edited
J. Doe Coca Cola 1000 500
J. Doe Coca Cola J. Schmoe 200 100
This data is brought in from two imports of data (there is actually a date column too that I didn't include). Now, what I need to do is have it subtract the "Pruned" from the "ResearchHis" and the "Edited" from the "HitsSent" while only showing Coca Cola and J. Doe once... is this possible?
Thanks.

I'm trying to build a query that will normalize some graphical data along the x-axis. To do this I need all the peaks to be at the same point. I'll just talk in generic terms of FieldX and FieldY for the X and Y variables (resp)
In my mind the steps require me to
1) Determine FieldX at Max(FieldY)
2) Determine difference between FieldX and arbitrary normalization point (probably 100k)
3) Shift FieldX at all points to put Max(FieldY) over 100k (its a log scale so I'll be dividing)
Steps 2 and 3 are easy, but step 1 is giving me grief.
Ok, so I know how to find Max(FieldY), easy enough. Now how do I find FieldX? My first thought is a complex series of subqueries. At some point in the past, where I was smarter than I am today, I created a query that would do numerical integration. Looking back at the query I can't understand it, but I think the principle will be similar.

I am attempting to normalize an existing database. I've created the table structures necessary and now I'm designing a query that will update the new field in my primary table: "LabelBaseProduct" with the primary key from my new table: "tblBaseProduct" where the old field from my primary table: "tblLabels.BaseProduct" equals the description field from my new table: "tblBaseProduct.BaseProductDesc".
A visual of my tables:
tblLabels (Main table)
- LabelID
- BaseProduct (old field with text data)
- LabelBaseProduct (new field, needs to be updated with PK from tblBaseProduct)
tblBaseProduct (new table)
- BaseProductID (PK and FK to tblLabels)
- BaseProductDesc (Field that should be matched to tblLabels.BaseProduct)
I tried to design a query using design view of the query design and this is what I have:
Code:
UPDATE tblLabels, tblBaseProduct
SET tblLabels.LabelBaseProduct = [baseProductID]
WHERE (((tblLabels.BaseProduct)=[tblBaseProduct].[BaseProductDesc]));
When I attemted to run the query it told me that it was going to updated over a million records. I only have just short of 2k records in my database.
