Normalizing And Table Update Question
Aug 20, 2006
I’m working on a new database which will record furnace logs for a heat treat company. I did my best to normalize the tables. I’m trying to add new records through a select query which updates multiple tables. My problem is I don’t believe I did that great of a job normalizing the tables because I continue to get errors stating I have duplicate entries. It dose not make any sense because each table uses an auto number as the PK and one FK value from the tblProcessFurnace which is an auto number. Every new record should increment the PK. Thus making it impossible to have duplicate values.

Alrighty,
I am going to take another shot at making my inherited database like the others I see. It is an inventory questionnaire. It seems most of the information is stored in 1 table . I have read much on this forum about normalizing and I understand this is to stop duplicates. I would like to normalize this database and create it in Oracle. I have tried recreating it.
The database tracks assets and the people who own and manage them and there risk.
I have one table called
tblAsset - It holds everything about the asset including the risk rating and summary.
tblAssetformat - are the formats of the assets for dropdown query
tblImpactItems - is the risk impacts for dropdown query
tblMasterplan - are the decision teams dropdown query
tblRiskLevels - are risk levels for dropdown query
My form is usually a query and all the information on one screen.
When I tried to normalize it before it appears it should be the following:
tblAsset - Asset Name, Asset ID, Asset Description, Asset format, Asset Location
tblInventory - Conf Risk level, Integ Risk Level, Impact,
tblowner - Owner department, unit, masterplan.
Any assistance would be appreciated.

Greetings,
I have a friend who is using Excel to track a Greyhound Protective Association roster. These are folks that foster and adopt Greyhounds -- thus a worthy cause. It has over 600 rows of data.
I've attached 50 rows of sample data in Excel format.
Along with contact information, there are also fields to track up to 5 dogs. I've gone through the spreadsheet and tried to set it up for import to Access 2000. I have the dogs numbered 1 through 5.
I'd like to set this up in two (or more ??) tables, with Contacts in one, and the dog information in another. I'm guessing it will be one-to-many (Contacts -->Dogs).
However, I can't for the life of me figure out how to get this all together so that she can use a form-subform setup to input / access the data.
I'd like to pull up a name in the form, and have the subform display all of the dogs that this person has adopted, with the ability to add more dogs. Thus, they could have one dog, or 2 dozen dogs.
Any assistance would be greatly appreciated !! Thanks in advance.

Hi all,
I am new to this forum and a rookie when it comes to Access. I inherited a pretty complex db and from my experience from other forums as well as trouble coming up with accurate queries I have come to the conclusion that normalizing the db is the only solution.
However, I really need help with this process.
I have attached a simplified version of my database with only the tables (all the #s and data are fake).
Basically what this db does is track lease hold improvements for various groups (ADT and RWA) and the tables are split up to reflect the 2 groups.
I will focus only on the ADT tables as the RWA is basically the same thing (Dont worry about GSA and the other stuff). The main table in the db is the ADT_Detail which includes all sorts of data regarding "Projects". I will provide information on each field:
Project- Project numbers numbers are unique, but often have multiple DCNs (and there's not always a project number so that can cause a null value for primary keys).
DCN - Each DCN can have multiple projects associated with it
TO - Task order can be the same for everything
SiteCode - A number that identifies various locations, there is another table that lists all the site codes and pertinent info on each.
CostBase - A currency figure on the original cost of each Project
Useful - length of useful life for each project
Complete-Expense - yes/no field
Complete-Cap - yes/no field
WIP- yes/no field
(any project can have 1 or multiple yes for these)
InServ Date - Date the project is placed in service
Start Amort Date - Date amortization starts on the project
date add LHI - the date the project is entered into the db
Fund- a number where the project is expensed
Post Fund - If a fundis not available for the project this is what is used by the DCN and is usually the more important one
Year- when the project begins
Post year - If a year is not available for the project this is what is used by the DCN and is usually the more important one
Deletion - yes/no box so that we can keep a track of what items we are deleting to compare with other periods
Deletion date - used to identify Quarter that the project was deleted
There is also a table labeled (ADT_Master) which contains other data for each project. This is pretty self explanatory when you look at the table.
Everything is also based on quarters when we ran queries to show additions, deletions, adjustments in certain quarters based on the quarters table.
This is probably more info than what is necessary but hopefully it will give you an idea of whats going on. Let me know if you need any further clarification and I will try my best to assist.
Thanks in advance.

Hi,
Just was asked to create a new db
Basically it's going to track provider/member information
Here is where I'm running into a issue.
I have a provider table, it has the name, rider#, and I need to list the 'clinic' the provider belongs too. I orignially thought since many providers can belong to the same clinic. I would created a clinic lookup table..
but then I started thinking, how in the world would I keep that updated? There are tons of clinics out there, and I have no way of knowing which ones need to be in the db.
So then I thought, should I just have clinic be a text field and the user will just type in the clinic name when they enter the new provider info? That would work, but it's also creates duplication in the db, and what happens if one person enters a new provider and spells the clinic name wrong? OR what happens if a clinic changes it's name all together?
I would have to run update queries to fix all that. Doesn't seem like the right way to go about this.
So how would you do it? Keep the database normalized, but also keep it easy for the users to update and maintain when creating records?

I have a 1000 records with 4 columns , now normalized.
I can use set to update and set some of the records. Perhaps there is a method I am missing. Is there some script or stored procedure I can run in sql to speed this up.
I have 181 units to match 1000 records as well as business leads any hints would be appreciated.
I am matching the DepartmentID in the department table back to the field on another table.
Thanks in advance
Regards
Angel

Hi folks.
I'm going over a laboratory application that I started a few years ago, trying to do a better job with some of the table structure that I set up, and improve the application. Right now, I'm working on the very first thing I did when I started building this application. This part has users pick a sieve stack setting for a size test, and record the grams of material weighed from each sieve in the test. This stack is based on the top and bottom size of the sample. In the original, I used a field for top and a field for bottom. In the new structure, it's together. There are over 100 different sieve stack combinations, and the number of sieves used in a combination for a test varies from 3 to 8. The way I was told to set it up is not in a normalized table structure, but it has worked fine for us to date.
I've gone in and broken the tables up into what I believe to be a normalized structure. The funny thing is, the size of the db is bigger with the tables put into a normalized structure than it is with the orignial, non-normal structure.
This seems weird to me. I've done this with other sets of non-normal tables in the application, and saw a subsequent shrink in db size because of the optimization of the table structure. Now I'm wondering if I've done this right, so I'm asking if some of you experienced hands can look at this and tell me if I've gone wrong in my attempt to normalize the table structure.
I appreciate any input in this issue, as it has me scratching my head a bit. I've posted db1, which is non-normal, and db2, which is normalized (I think). I put a few records in these, so you can get the gist of the application use. File size with these few records is negligible, but the application has over 18,000 records in it, and the file size difference is over 1MB, which was unexpected.
Thank you.

I need some normalizing my data properly, and then showing the values in a form.
Currently, my table relationships look like this;
However, there can be multiple Genres per Band and each Genre will be applied to multiple Bands, and I know this is a Many-To-Many relationship, but I'm uncertain on how to create this properly and then show it in a subform in a form.

I have a table called tblCompanies. When a company acquires another company, I need a method by which the acquired company's CompanyID (PK) can be updated to the new company's CompanyID (PK). I also need to be able to update all related CompanyIDs (FKs) to the new value in related tables.
In cases in which the new company does not have an existing record, there is no problem: the company name simply gets changed to the new company and the existing CompanyID is maintained. I then use an audit table and Track Changes function to keep track of the company name data and a union query to keep the old names in the selection lists.
The problem is when both companies already have existing records in the table.
So, let's say I have records for Company A and Company B. Company A merges with Company B and Company B is now the main record. What is the best, simplest and easiest way to update the CompanyID (PK) from A to B and change the CompanyID (FK) to the new value in all related tables?
I am envisioning a pop-up form that directs the user to select the new company and then an update query happens behind the scenes... but exactly how does the criteria for the update query get selected and how do all the related tables get updated? My vba skills are pretty basic, will I need extensive coding to do something like this?

I have one DB that is used for creating/storing customer ID's, and another DB that is used for creating/storing job information for customers.I have linked the table from the customer DB to the job DB.
There is a table in the job database that holds customer name and ID, and some VBA that generates unique job codes.
Is it possible to have the data from the linked table automatically update into the existing table?

The attached Access XP file demonstrates my problem. I've included a form to make testing easier.
Each record in the Projects table has one or more linked entries in the Keywordlink table, showing keywords that apply to that record. Each record in Projects has a Yes/No 'Utility' field.
A third table, Keywords, supplies the keywords that the user can apply to records in Projects, using the subform on the main form. The Keywords table also includes a True/False 'Utility' field. I have set this to True for for the first three keywords.
I need a query, a series of queries or some VB code that updates Projects_Utility for all records to True if and only if the record's linked entries in Keywordlink include all of the keywords for which Keywords_Utility is True (a boolean 'and', as opposed to an 'or'). Otherwise, Projects_Utility must be set to False.
In the attached file, with the current settings in the Keyword table, the 'GetSelectedProjects' query should then produce single-row listings for ClientA and ClientF.
I'd appreciate any help you can give me on this. I'm not a programmer, but I can manage a bit of VB code if I have to.

I'm using an UPDATE query to update records in one table (tblMain) from another table (tblTemp)
Here is my SQL :
Quote:
UPDATE [tblMain]
INNER JOIN [tblTemp] ON [tblMain].[MainField1] = [tblTemp].[TempField1]
SET [tblMain].[MainField2] = [tblTemp].[TempField2];
I only want to update the records in tblMain which have a corresponding record in tblTemp (linked by MainField1 / TempField1)
If any record doesn't appear in tblTemp, I want tblMain to retain the existing value for that record.
However, it appears that in such situations, the record in tblMain has it's MainField2 value set to null / ZLS.
I've tried using LEFT JOIN and RIGHT JOIN and also tried WHERE clauses but the result is the same every time.

I have an "order details" table that needs to populate a field called "Voucher" with data from another table called "codes". The "codes" table also has a true/false field called "allocated" because once allocated the code cannot be re-used.
I am trying to work out how to automatically allocate the next unallocated code in the "codes" table to each record in the "order details" table when that order details record has a DiscountID of "92".
Order Details Table Fields and conditions/criteria:
ID - primary key
DiscountID - only when the DiscountID = 92
Voucher - only populated when Discount ID = 92
Codes table Fields and conditions/criteria:
ID - primary key
code = text field with a code like "einstein01", "einstein02"
Allocated = False
Is there a way to put the next available code into the order details record then mark that code as allocated in the codes table. Then, move on to the next order details record that has a discountID = 92, input the next unallocated code and mark that code etc. etc.
Ideally, I would like to do this to happen via an event when the Order forms button "Close" is clicked.

I have created a code below to test whether I can run a query and retrieve a data from an SQL server table. And so far I can return the result using a messagebox. but somehow I just don't know how to use this connection to update the table inside this access file. Basically I want to use this as a front end file. then when the form is open it will automatically update the table inside this access file and load the data to the combo box as a list.
Code:
Option Compare Database
Sub LocalServerConn_Test()
Set conn = New adodb.Connection
Set rst = New adodb.Recordset

I have a combo box (cboManifestNumber) that is based on the following table:
tblManifestData
ManifestDataIDPK (autonumber PK)
ManifestNumber
RemovedDate
ManifestComments
TsdfIDFK (FK frm tblTSDF)
This table is related to:
tblTSDF
TsdfIDPK (autonumber PK)
I need to be able to update tblManifestData with a new manifest number and manifest comments, along with assigning it a TSDF. how to be able to enter a new manifest number and the associated data without having it create two lines in tblManifestData. I thought that I could enter a new manifest number, then requery the table and form so it shows the complete list of manifest numbers (including the recently entered one) while staying on the newest entry.

MS Access 2013: I have two database tables as below:
tbl1_MainDB --- It has a field named as "City" where I get huge data for some city names. Sometimes This field may have some unknown/new names which are not listed in our 2nd table ("tbl2_RefrDB")
tbl2_RefrDB --- It's a reference table which has raw names for cities, and then standard names of their city and state in another fields.
Target --- I want to create a VBA prorgram (Sql query) which can look from tbl1_MainDB.[City] to tbl2_RefrDB.[Raw_City] field, and if found then pick the "Standard_State" and "Standard_City" record values from there, and update into the 1st table "tbl1_MainDB".
...if not found in "tbl2_RefrDB" table, then user can be informed & ask for updating the new/unmatched city record as a new record in this table.
Attached sample database for more details.

I have a form that contains the following: Combobox, (Lists BadgeNum from tblPersonnel)
2 Textboxes (LastName, FirstName) populated via code from the combobox using info from the same tblPersonnel.
2 labels (one containing Date, another containing Time)
ToggleOnButton (Valueof 1)
ToggleOffButton (Value of 0)
Savebutton
This form is basically used as a cheap police timeclock. All Im trying to do is when a user chooses their name from the combobox, clicks ON or OFF and then save, is just write the much of the same info to a table. Specifically, BadgeNum, DateIn, TimeIn, DateOut, TimeOut.
