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.
How to properly normalize dates in access. I have read many things and have actually normalized dates before in the past but feel that there is a specific correct way to accomplish this without having to jump through many hoops on coding and query design.
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 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.
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.
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.
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
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.
How does normalizing affect current queries and forms?I need to normalize a database here at work, the original creator made one BIG table.My concern is how will that normalization affect the current queries and forms I have created based on the current table?I tried the Wizard but that wont do the job I will have to do it manually.Thanks
Currently trying to build a database for customer management and order placement/tracking. Want to set a couple of rules so that if I for instance click yes of billing and shipping address the same that the database will automatically fill the shipping address with the data I inputted for the billing address in the same table.
The other issue I can see I'll run into is, I want to be able to select one of the company ID's (made up of a three letter abbreviation of the full company name) in the product ordering table and it will automatically fill in the rest of the customer data (phone, email, address etc) data into that form.
What I have is a database setup with multiple tables in which different areas of my DC can input information simultaneously into their respective tables. I then have another database linked to it for myself to have a live view of each updated record. I would like to see all the records of each table in 1 single table (possibly just sorted ascending by time). Each table has the same Field headings but may have different qtys of records. As I will then have it linked to an Excel table to VLOOKUP from it.
I have tried Union coding but always get Syntax Error etc.
I'm using the MS Access 2010 ExportwithFormating action to export three tables to a single MS Excel 2010 workbook. The action overwrites the first excel worksheet each time instead of saving all three worksheets in a single excel workbook.
How can I export three tables into a single excel workbook.
I have created a table that acts as a header for my data and a second table that acts as line item data. What I need to do now is add a second child table that uses the line item data as its parent table and stores associated line items for each record. Is this possible?
I am using calculated field as a data type in access 2010.
They are working fine.
However, I added a new field and now the final calc won't work.
I have Subtotal adding loads of fields together. Works fine.
Then I have a VATunit field which is a double integer, so enter 20 and my next field is VATTotal calculates the SubTotal + the VATunit by doing (Subtotal/100)*VATunit. This calculation is fine and gives me the correct amount.
The next field is a Total field. Which adds Subtotal and the VATTotal together. Howver, the Total is the same as Subtotal. It is not adding the VATTotal to it?
I have some experience doing 'Update Query' using two different tables but I'm having a hard time doing an 'Update Query' using 3 tables.
I have my source table TP05XY with the fields 'Mark' 'Date' 'UTM_Edig' and 'UTM_Ndig'. Mark and Date are my primary keys (they together uniquely ID each record). I have my Observations table with the fields 'Mark' 'Date' and 'Obs_ID'. The last table is Locations with 'Obs_ID' 'UTM_E' and 'UTM_N'.
I want to update my fields UTM_E and UTM_N from UTM_Edig and UTM_Ndig. However, to do so, I have to go from my TP05XY table, through Observations table to update Locations table. Table TP05XY is joined to Observations through 'Mark' and 'Date' and Observations table is linked to Locations through 'Obs_ID' field.
I have tried a few options without success ... anyone knows how to do it?
I have being playing with ms access but I really don't know much about it or databases in general.I have created a very simple database to gather twitter following/followers data for research purposes.One table (table01) has a field for the "boss" user (=the user who I gather data for), another field for "client" (=bosses followers or friends).Both fields are numeric and contain the users id's.In order to distinguish if the link is follower or friend there is a third field, called type which can be either 1 (=follower) or 2 (=friend).So the data would look like this:
boss - client - type 12345, 67890, 1 12345, 54321, 2
If user with user id 12345 had a follower (type 1) with user id 67890 and a friend with user id 54321...In order to avoid getting duplicate rows I also added a unique identifier which is of the form boss_id-user_id-type.So the above row looks like this:
That works just fine.For several reasons I also needed data of the form source - target.So I also made another table (table02) of this form.
67890, 12345 12345, 54321 ...
In table 2 you don't need the "type" field since the position of the user id shows the type of relationship.Still, you need a unique identifier in order to avoid duplicates, so I added on with the form: source_id-client_id..So table02 lookes like this
Both tables also have a date/time stamp for each line.As you can see, table01, having also a type field is bigger than table02.The problem is when I try to append data, exactly the same data in both tables.Appending data to table01 is ok, while appending data to table02 (which is smaller, having one less field) takes a really long time, maybe 10 times as long as appending data to table01.To make sure that no query's are causing the problem I have tried first creating temporary tables with the data to be appended, no duplicates, nothing that would cause the database to make extra calculations and used a simple update query with no filters to append data.Still I get the same result, table02 takes a very long time to finish while table01 finishes in no time.
I am currently using Microsoft Access 2010 32bit, and have one database acting as parent, with a second linked database as a client for people to work with, and the parent database has tables imported from Sage V21 via ODBC. I have used the following code as specified in other examples as follows:
one of the tables has 10k records in it, it only transfers 77 records. After manually attempting an import via the ODBC wizard it finally lets me access all 10k records.I wish to have a single button click delete and import fresh tables without worrying if all the data is coming across.Also, when manually adding a table, I am usually asked by the wizard to specify an index, but with the code above, I am not offered that option and the tables come across with no index. I am led to believe that having tables that link to each other without an index is bad, so how do I ensure an index is created?
I have two tables of data, each relating to three business branches (branches A, B and C).
Table 1 shows the expenditure of each branch (by fuel, premises and wages).
Table 2 shows a number of units for each branch (mileage, floorspace and sales).
What I would like to do is calculate unit costs, based on the expenditure in Table 1, divided by a relevant unit in Table 2. The catch is that I want to have a third table which allows the user to specify which expenditure (from Table 1) is combined with which unit (from Table 2) to generate the calculated unit costs. I've been able to do this in Excel, and have attached an example. I've also attached an incomplete Access version with the first two tables. Given the complexity of my actual data, I feel this could be better handled in Access than Excel.
I have an Access Table with about 28,000 Automobile dealerships across the country shown. I've joined a new/small phone contact table to this to keep up with our phone contacts with the dealership and followup efforts. When I search/filter on the dealership table all is fine. However when I search/filter on the phone contact table with a few test entries, I get nothing at all. I supposed that after joining the tables, I'd be able to do a search on the field named follow up date and find/filter today's date or other dates and locate which dealerships to contact when the correct date arrives. But nothing.
I have developed a Microsoft Access 2010 database for my client and the database is split with Front-end/Back-end, the Back-end and the database is shared on Network, The client operating system and applications for all users are hosted and consistent and the service is delivered over Citrix.
The database some times corrupt the tables record and give a permanent #Delete Error, I have attached one of the database table and the screenshot of the error,
I want to fill local tables in some application with disconnected recordset. The tables in the front end application having the same table structure as in the back end database. The front end application was linked with the back end password protected database tables. I want no connected linked tables in the front end application. How can I fill the local tables in the front end application with the back-end password protected tables?
Table 1: contains staff names and contact numbers Table 2: contains training above staff have been on or need to go on Table 3: contains pc and printer asset numbers of above staff
I used a form and entered some new members of staff in table 1. They got their auto numbers etc but when I open table 2 and table 3 those new members are not showing up in those tables. I have checked the relationship status between the 3 tables and the staffID from Table 1 is associated to table 2 and to table 3.
What's stopping the new entries from showing up in tables 2 and 3 ?
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?
