Hi, I have a query with approximately 100 criteria. That is a bit much, thus I have made a table of the criteria and in the query a relation laid to this table. The criteria are countries with an increased risk on tbc. I point these query on a column with parent 1 and afterwards on the column with parent 2. Then I want the results from both query's in a table, but without double rows. I have tried this with a merge query but these only give the results where the hits for parent 1 and parent 2 are the same. This is by far not always the case, so, I miss all hits where there would be a hit for one parent only. Cumbersome tale, but perhaps there is someone who understands what I mean?
Hi folks, I'm new here - pretty hot at Excel but a total newbie at Access, So..
OK, I've got my database up and running. It keeps records of about 500 staff - everything is working fine but I now want to do stuff beyond my capabilities.. I've got a master record (Master Staff List) and a main input form (Data entry/amandment form). One of the input controls (via a sub-form) is for recording the time staff have spent working at a higher grade. Now if this was a one-off occurrence I could handle it but any one person could have multiple occasions that need recorded and I don't want to 'overwrite' the previous record. I have tried researching the problem and I think I need a 'one-to-many' relational table and a way to add a new period from the subform when required. The subform would also need to show blank when I opened it.
Hi guys, I'm fairly new to databases and am just creating sample ones at the moment and following tutorials from books. I tried to create my own cinema/movie database yesterday and there's something wrong.
I really wanted to work this one out for myself but after trying many different combinations of various relationships I just can't seem to get it working.
I have four tables..
A member table: MemberID A booking table: MovieID, Screening Number, MemberID A movie table: MovieID A screening table: Screening Number
So the booking table is a composite key that links the member tbale (via the memberid), the movie table (via the movieID) and the screening table (via the screening number)
The problem occurs when I try to make a booking form for members to book a movie.
I use the form wizard and take the following fields:
The MemberID from the member table, the Screening Number and MovieID from the booking table. Then I add other relevent information from the Movie and screening table (for example, screening time, date, price etc from the screenig table and movie name, information from the the Movie table)
The MemberID is displayed on the main form with the other information in a sub form.
The problem I am having is when I enter a booking on the form, I get an error telling me the Microsoft Jet Engine cannot find the screening number in the screening table or something like that.
It lets me enter the other information but not with the screening number.
Not sure if anyone can help. Its been about 10years since I've built a relational access database, but offered to build one for someone, but am now a little stuck.
Its a photo sales tracking db.
I have 3 main tables. Photos, Sales & Customers.
The main form is a photo form with embedded subform showing the list of the sales related to the photo. This works well!
The second form is a customer form with embedded subform showing the list of purchases (sales form) related to that customer. This again works, but I cant get it to show the photo title of that sale in that subform. I think I am missing some sort of link.
I have relationships between photos and sales, and customer and sales. But it always shows a blank photo title field in the customer purchases list
This is a very brief outline and I can explain in more detail if some thinks they can help. So far the database looks good and mostly works but it is all a bit relevant if I cant get the customer purchases to automatically show the name of the photo sold.
Hello everyone! I am completely new to MS ACCESS, so this problem might be fairly simple but yet it is eating my head.So if I get some directions it will be greatly helpful and appreciated. Description: The bakery buys ingredients from number of suppliers, makes a several kinds of cakes and sells to few shops. There are about seven ingredients in the first week with the possibility to add new in ingredients later on. There’s a catch though; on any day, only a single type of cake is made, in a single batch and all of them must be delivered before the next day’s cake are finished. It is necessary to be able to rack the ingredients used in a batch back to the suppliers. I have made tables for suppliers, ingredients, orders and order line (with fields ordereId, ingredientId, quantity, unit price). Forms that allowing users to allow new ingredients types, suppliers, and new order for ingredient are required which I have made. These forms are to be used to add the data for which ingredients are needed in the second week of baking. So these are my questions on which I am stuck in
1. Do I need any more Forms or do I need to edit my form? 2. Is it okey to put table as the data source or would it be better to place a query? 3. How do I keep records of my earnings and expenditure, expenditure and keep them updated with my databases? I hope you will understand that I am completely new to these topics and its really hard for me to grasp them all at once. Merely some guiding points will be of great help. Thank you. 6pandn21
Im trying to figure out how to model 'Printer' and 'Cartridge' information. The relationship between them is Many to Many, but to add to my confusion, more than one cartridge can be used in a printer (Black + different colour cartridges). Adding a new entity to resolve the Many to Many does not solve this issue of how a printer can have, for example, a black cartridge and 3 different coloured cartridges.
Any ideas how to model this please?? I have been toiling with it for some time and I keep going round in circles :confused:
I'm sure it shouldn't be as difficult as it seems, so I'm hopeful someone might be able to set me straight :o
So all the members are realized by single columns. I created a new database, consisting of the main table, the "people" table and a relation table, connecting the people with the compartment (n:m relation).
It works great but I have to get the old data into the new tables. The old main table consists of more then 100 columns, and most of them are now hived off by using relations.
Now I'm looking for a smart solution to convert the table.
Do you have any idea? I tried to use a Query, but I couldn't merge two or more columns and put them in a single one on a new table.
Hi all, i have a relational database. In a form, Transactions, i have a text box, CustomerID, which relates to the primary key of the customers table. At the moment, if i enter a number that has no related record in the customers table, it will alert me only when i try to close the form or move to another record. I am wondering if it is possible to check for a related record immediately after the text box loses the focus.
The first time a person tries to use Microsoft Access, they are likely to miss the whole point of what a database is and how to use it. When they start having trouble making it work for them, they think in terms of what they may be doing wrong in their use of the obvious tools of Access. But often their problem is that they are unfamiliar with the principles that make databases so useful and they have started with a flawed database schema.
This tutorial is intended to explain the underlying principles of relational databases. It is, admittedly, rather theoretical and perhaps even boring. But without an understanding of these principles, a beginner cannot hope to use Access for any really useful purpose. If you are a beginner, I urge you to read through the entire tutorial.
There are several issues that arise time and time again, such as:
. Storing multiple values in a field. . Storing calculated values in a table. . Determining primary keys. . Using Autonumbers. . How many tables does this database need? . Why don't my queries work?
Sometimes answers in the forum make it sound like these things are a matter of preference, or "which is the best?" But in most cases, they are not--there are well established rules that determine the one correct answer. It is only with an understanding of the principles of relational database theory that you can determine the answers.
So I hope you will find it worth your time to study this 7-page tutorial. If you think you've found something in it that's incorrect, incomplete or impossible to understand, please feel free to contact me. I have been known to make mistakes!
Im creating a data access page overtop of a relational database. the database is simple... it has customers and workorders. there may be more than one workorder for a customer.
When I create a new customer record through my data access page, I want it to automaticly create a new workorder (filled with 0's)
Does anyone know how to do that?
Thanks --Ben
PS: I understand SQL... I just need to know where to enter it (if necessary)
Hi! I have a table named Employee Records, with a primary key "ERName". I use this to link to a table named Certification Records, with ERName as the link in both tables. My problem is this:
When I add a new record to Employee Records table, the name is not thrown in to a new record in Certification Records. This is a problem, because in my form that uses a query that includes both tables, when I add a certification record, it doesn't populate the name field in Employee Records table. I don't know where I went wrong, but I feel stupid because this is so basic and I should have caught it earlier... any ideas, please? Thanks!
I have a simple relational database with the proper linking tables, etc. I am normalized through BCNF. I have a table that will track tasking details, however, more than one person is assigned the tasking. How do i add to my form the ability to add additional people to the tasking?
If I drag and drop the name field then it is a one name for one box deal. I want to create a combo box that uses a query to prepoulate multiple elgible names (already built) and then you can select the person you want. Afterwards I want the task assigner to dynamically add additional people to the task with no true limit as the group can be as small as one and as large as thirty.
I attached a small screenshot of the basic table structure. I need to be able to add multiple SME's to the one tasking...
I'm attempting to set up a relational database utilizing a composite key of several data fields. I had no problem doing this with FileMaker Pro yet with Access 2003 I'm having problems. For example, in Design View I select the field names needed for the composite key.
Yet when I click save I get a message "Microsoft Access can't save property changes for linked tables." As a result I'm not able to construct a composite key of the several data fields selected.
I have two tables, tblCountry and tblLocation. With the following structure
tblCountry ID Name Text
tblLocation ID Country_fk Name Text
As you can guess tblCountry lists all of the countries, tblLocation lists all of the locations in each country, the tblLocation.Country_fk field is linked to tblCountry.ID.
I want the user to be able to edit [tblLocation].[Text] using a form. They simply select the country and then the location using combo-boxes and then add or edit the content using a textbox.
In my form I have a combo-box that displays the country names, the RowSource is set to SELECT [tblCountry].[ID], [tblCountry].[Name], FROM tblCountry ORDER BY [Name];
I then have a second combo-box that lists the locations for the selected country. This uses an AfterUpdate() procedure to select [tblLocation].[ID] using an SQL query based on the value of the country combo-box. I.e:
SELECT [tblLocation].[ID],[tblLocation].[Name],[tblLocation].[Text] FROM tblLocation WHERE [Country_fk] = " & Me.country_box.Value & " Order By [Name]"
I want to be able to have a textbox that then displays [tblLocation].[Text] for the selected location. Thats where the problem arises. I can't find a way that will let me display any content thats available for the selected location AND let me edit it. I've tried using UpdateAfter procedures, different bindings (tables, queries based on the value of location combo-box).
Can anyone suggest how I can display [tblLocation].[Text] based on the value of the selected country/location and be able to update the information via a textbox?
What I've done is created a form based on the tbl_customer table and used tbl_rates as a sub form. tbl_destination is used to populate a combo box that is situated in the sub form.
Each customer has their own rate sheet. Each rate sheet has different destinations and rates. Rates for the same destination are constantly changing. I need to use this spreadsheet to record the history of every change made to the rates of a particular destination. To do this I've just added the same destination with a new rate.
Now, what I want to do is to create a query that will only show the latest entry of a particular entry.
I used to queries ,1 to get items that are taken ( its all about sign in sign out for equipment) and other query is list of all items. How can i make 3rd query which will give me all but taken items from query1? (of course items from query 1 are in query2) thx in advance
i was wondering how to go about doing this, i currently have a query which returns all the payments due in the next month, going to a report which acts as an invoice. I was wondering how to create a unique id for each invoice and store the last id so that i can automatically itterate it later
I have a query of 11 employees and their pay for jobs done. Only problem is there are 15 completed jobs with some of the employees doing more than one. When I run my query its only displaying unique name results so I'm only getting 11 results of the 15 jobs instead of all 15.How would I change the query to that the results are only unique employee names?
I have a roster of people where each person may work on a specific task during a given period (a month, or a quarter, etc.) and each person is assigned to a team.
Team Jones has 30 people on it. There are 5 tasks that a person on that team may or may not work on during Q1 of 2013. Here are those tasks:
1. Business Analysis 2. Project Planning 3. Testing 4. Test Planning and Preparation 5. Quality Inspection
Now, what I want to do is to find the unique instances for each task where 1 or all of the 30 people worked on that task for the quarter. To further illustrate, say for Business Analysis that Mary Smith did Business Analysis in January, February, and March. She performed that task 3 times (1x in each month) but I am only concerned about knowing that she did perform Business Analysis during the quarter (so I'd like to show a 1 instead of 3).
Ideally, if everyone on Team Jones did Business Analysis during the quarter at least one time, I am only concerned about the one instance where they did and the first occurrence of it, not the other occurrences. So if everyone did do Business Analysis for the quarter, my total count should not exceed the count of members on the team (in this case, the 30 people). So the distribution could look like this (I'm just making this up but this is what I'd like to see):
Task Team Jan Feb Mar Total
Business Analysis Jones 7 15 8 30
My fields in the table are: 1. Task 2. User 3. Date 4. Team (there are 5 different teams)
I don't know if I'm going about this problem correctly. In a nutshell:
I have a table which contains a number of fields, only a two of which are important for this task, as indicated below.
| ID | Type |
Where ID is an alpha-numeric identifier (say a store number), and there are three potential types, plus Null values. For this, we'll assume the three types are Fruit, Vegetable, and Grain (plus Null).
An example dataset might look like:
0-4 Vegetable 1-2 0-1 Grain 1-2 Fruit 0-4 Vegetable 1-2 Vegetable 0-1 0-2 Fruit 0-4 Grain 1-2 Fruit 0-4 0-1 Vegetable 0-3 Fruit
If I want to know how many stores have Vegetable, I could put "Vegetable" as the criteria in the query and set UniqueValues to Yes. Then I would get three unique values, one for each Vegetable existing at a unique store.
But, what if I want to know at which stores Fruit exists and Vegetable DOES NOT. Is there a way within Access to find all the records with "Fruit" as the criteria and then eliminate those with ID numbers matching the dataset with "Vegetable" as the criteria?
In other words, if I do my "Vegetable" criteria I end up with the resulting dataset:
0-4 Vegetable 1-2 Vegetable 0-1 Vegetable
If I then use "Fruit" as my criteria, I get the following dataset:
1-2 Fruit 0-2 Fruit 0-3 Fruit
Since Store 1-2 has Vegetable, I want to eliminate it from the list so that my resultant list is:
0-2 Fruit 0-3 Fruit
Is that possible? Sorry for the long bizarre example, but I thought it the easiest way to make the situation clear. I'd really appreciate any suggestions anyone has on dealing with this situation!! Thanks
I'm having trouble getting a query to return a simple count of unique lot numbers for a given ProductID. The data is stored in a large table where each test result of a stability program is stored. Each result has an associated lot number, product id and several other data fields. I've managed to get a combination querries to return the count, but if the lot has both real time and accelerated data then the counts are added and reported as double for each type. The current SQL is as follows.
SELECT tblProducts.ProdName, Count(qryAccelerated.Lot) AS AccelCount, Count(qryRealTime.Lot) AS RTCount FROM qryRealTime RIGHT JOIN (qryAccelerated RIGHT JOIN tblProducts ON qryAccelerated.ProductID=tblProducts.ProdID) ON qryRealTime.ProductID=tblProducts.ProdID GROUP BY tblProducts.ProdName ORDER BY Count(qryAccelerated.Lot) DESC , Count(qryRealTime.Lot) DESC;
qryAccelerated and qryRealTime are simple SELECT DISTINCT querries returning the product id and a list of unique lot numbers for that ID.
(e.g. SELECT DISTINCT tblResults.ProductID, tblResults.Lot FROM tblResults WHERE (((tblResults.TypeID)=3));)
Currently the top query returns 4 in the both the AccelCount and RTCount columns when there are only 2 unique lots for the product. Other products without both real time and accelerated lots count correctly.
I am trying to set up a query to select PaymentDate, CustSurname, CustForename, AgentName showing only the last record for each customer if the last payment is over 7 days and also include customers with no payment.
I have tried the code as below: but it now gives me every payment for the defaulters as opposed to just the last defaulted payment. Can you shed any light on what I have done wrong.
select b.PaymentDate, a.CustSurname, a.Custforename, c.AgentName, d.LoanID from tblCustomers a, tblPayments b, tblAgents c, tblLoans d where d.LoanID = b.LoanID and d.CustID = a.CustID and d.AgentID = c.AgentID and (DATE()-(SELECT max(PaymentDate) from tblPayments f where f.LoanID=d.LoanID ))>7 UNION select '' as PaymentDate, a.CustSurname, a.Custforename, c.AgentName, d.LoanID from tblCustomers a, tblLoans d, tblAgents c where a.CustID = d.LoanID and c.AgentID = d.AgentID and (select count(*) from tblPayments where tblPayments.LoanID = d.LoanID) = 0;
I got a large transaction file with deplicated records!! For unit price checking, I need to copy the last 10 unique records to another file with the same criteria but price is not the same as the current checking record.
For instance, I got 5000 records with around 400 records unit price is not the same as history. For each checking, I needed to copy the same criteria historical records to a tempory file and then delete corresponding duplicated records first, following by another deleting action only to keep the last 10 records according to date field.
I have been working on a simple data base for some time now (beginner level) and am still trying to improve it. I would like to do something but before that I would like to have your opinion to know if it is even possible?I have a query QryMainReport:
Start Date/Time End Date/Time Employee
At the moment this is what the format of my report looks like (I removed other unnecessary fields):
StartTime----------EndTime---------------Employee 12/06/2014 01:00--12/06/2014 03:00------John Smith 12/06/2014 04:00--12/06/2014 06:00------Jane Doe 13/06/2014 02:00--13/06/2014 05:00------John Smith 13/06/2014 08:00--13/06/2014 08:00------Jane Doe
I would like to do as a report. (Dates would always be from Sunday to Saturday). I am not sure it is possible to do that. I suppose first it would mean:I would have to do a query to separate the times from the dates?I would have to find a way for Access to find the unique dates and unique names?Does it mean I have to use cross tab queries?
