Hi there,
I'm a bit stuck on this but it should be pretty easy.
Say I have a table secondHandCar - this contains infromation on the makeID (eg 123), price, number of doors. Now each car can have a number of images, this number isn't set so I have an images table...
tbl_secondHandCar
makeID - key
price
number of doors
Now clearly I have a problem: the images table is going to have many makeIDs with different images. I've just got stuck here - do I need an image id or something? But then my make ID will still repeat in tbl_images.
I've split a database and the backend relationships are still intact but the front end they are not and it looks like this is causing a problem. Is this usual?
I'm (as said before) totally new to everything that has to do with programming, and therefore I work in the visual way, and thus I need to have the reports shown in relations in order to work with it...
After designing the database that mean after creating all the tables and when pressed on relations buttuon it shows a diagram with relations established. Is this a kind of ERD. in this it shows relations between entities so can we call that an ERD?
Hi, I'm trying to build a mdb which holds customer details, which insurance they have, who sold them this and which Insurance company provided this. The relations I have to make are driving me nuts ! When I try to enter a new customer in a Form, there is a advisor added, the package the customer wants is added. But this shouldn't happen for the advisor and the package allready exists !
Who can help me with the proper relations ? Attached is screendump of the current relations.
I have a DB and for some reason queries aren't working properly. My guess is the table relationships I made. If anyone else has an idea on changing my relationships so that all forms and queries will work to thier full potential please give my DB a look.
I would create a one-on-one relationship between coGeneralContactID and coPostContactsID. And now I can create my one-on-many relationships between from the Postalcodes table.
1) Is this clever? 2) Should both these fields have a key? 3) I set coGeneralContactID to autonumbering and coPostContactsID to numeric. is this also correct. 4) I also use prefixes before the fieldnames 'cp-' for 'ContactsPost' is this naming convention ok? I think it makes programming easier. But are there condingstandards for that in Access/VBA?
Can anyone shed light on why my Database seems to have stopped working so far as I've a combo box on a main form, which provides one half of a PK/FK relationship. The subform displays one or more records for this value. However, I've just entered the same 'value' (string) for an entry in the combo box as another, which shouldn't display any records in the subform yet - but it displays the records of the first combo 'entry'. This important thing is that the key's are all unique (I've doubled checked this), so why does it seem to not work? Please.
I have 3 tables Metrics, FixedExpenses, Variable Expenses, I want them all to have a date in a form, and a subform for all the records to be added. I want to be able to do this without having 3 seperate date tables linked to the other three tables. I am not sure how to do this correctly. (I want to be able to see all the records for a certain day in these forms.)
I have a table named [Brand] and several tables named [Brand@@@Models], one for each field in the Brand table.I want each field from the [Brand] table to be related to it's specific Model table. I thought like that so I don't have a Brand#1 related to Brand#2 models, etc.. I didn't want to have all the models for all the brands in a single table, was I right to think like this?
Ok I am right now making a simple Vendor/Product database to create a line sheet for some sales folks. I have 3 tables: Vendors, Products, and an associate entity Vendors_Products to relate the two. I have a form currently that draws the Vendor Name (primary key) from the Vendor table and the Product Name from the associate entity. This allows me to create new vendors and select current product types from a drop down box. The problem is that the drop down box is too long and it is tiresome when 1 vendor has 10 product types.
Can anyone tell me how to resolve this? I thought it would be better to have option buttons and display all available products. Then you could just click all of the option buttons that apply to that Vendor and it would create the relationships...is this possible?
Hi, I have looked at some of the threads here and it is clear that many of you are working on a much higher level than me and with a high degree of familiarity with the programme. I am hoping that someone here is able to give me some advice as I don't find the MS help files digestible. The task I have is to join 2 databases and produce a table from which I can run a mailmerge. I have managed to join the 2 databases and I used a customer ID as a common link. (my apologies if the terminology is incorrect) I now have all the data I require in one table. THE PROBLEMs I have multiple entries for some of my customers and would like to reduce this to single entries (which is understandable). Please tell me how to do this if you can, and keep it as simple as you can please.
I'm making a report detailing competitors final finishing positions in a competition.
The columns are (1) Place, (2) Name and (3) Points
I have the data for their names and the points they have scored, but how do I make the table enter the record number (starting at 1) in the first field???
Not sure what the issue is here but i am trying to append a Job number from a main database into two connected databases. The number is a sequential number i have created and the primary key. It is an autonumber field(obviously). The format is J0000 and the numbers start from J0001
I am using two different append queries to append them into the external databases tables. However (and here i think lies the problem) the fields i am inserting them into are text fields with the same format J0000. When i view the numbers in these tables, they are displayed as J1 or J9. The 0's are missing. Any ideas.
Hey guys, I'm just wondering how I could limit a field to using from 2 - 20 letters. If I placed the letter "a", I'd get an error saying how at least 2 letters must be there, and a maximum of 20. How would I do this?
Lastly, how can I make it so when I enter data into a form, I can click a button which adds it all into the table? When I do it normally, it's automatically transferred into the table as I type it into the form.
This is incredibly simple I know, but I am a n00b at Access. ^_^
OK, I have a strange problem... This doesn't seem to work..... It did... then I made some changes.... Can someone clue me in on what I am doing wrong? A query, simply summing some values in fields... no biggy...... BUT... The field TotalHours: ([SundayHours]+[MondayHours]+[TuesdayHours]+[WednesdayHours]+[ThursdayHours]+[FridayHours]+[SaturdayHours])
So why isn't this working? Can I use a simple VBA statement to sum these fields?
I am trying to create an IN query (ACCESS) which will firstly show the customers table (specific details) then the orders details should be in the IN query, I formulated this but it won't work:
SELECT s.CustomerID, Address, City, PostalCode FROM Customers s WHERE s.OrderID IN (SELECT s.OrderID FROM Orders p WHERE s.OrderDate = '1996') AND s.OrderID IN (SELECT s.OrderID FROM Orders p WHERE s.OrderDate = '1997');
Here is the one I did to show the customers and orders who made orders in 1996 and 97:
SELECT Customers.CustomerID AS Customers_CustomerID, Orders.CustomerID AS Orders_CustomerID, Customers.Address, Customers.City, Customers.PostalCode, Orders.OrderID, Orders.OrderDate FROM Customers INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID WHERE (((Orders.OrderDate) Between #1/1/1996# And #12/31/1997#));
it is probably something simple I am missing here! Sorry to keep asking :(
but I can't seem to figure it out. All I get is Null values when I run the query.
I have a form with a start text box and a end text box. I use the form name sucessfully in the criteria row so I know there is no problem with the form name. I also know there is no problem with the qry name. Does anyone see anything I am doing wrong?!?!
The query I am working in is labeled [qry_old_summary_date_range]. Just wanted to clarify that is not a problem.
I have a table with dates of deadlines and another with dates of submissions. For each deadline I want to know who submitted first. I figured that all I had to do was compute the difference between the dates and the select the minimum. However, Access rejects the Min() function in the WHERE clause. How do I avoid this?
I have a table (imported from excel) that is a pricing grid for blinds. The header row at the top is widths(mm) and the header row down the left is heights(mm). The data is the price. The import process makes the widths the column names.
height 600 800 1200 ... 300 $60 $80 $100 600 $80 $100 $120 900 $120 $140 $160 . . all I want to do is to take that table and make it flattened, like this:
I can't think how to do this in a query - I could take the flat version and create a crosstab to go the other way. Any clues - I don't want to change too much about the way the imported excel file looks becasue I have no control over that (I already discard miscellaneous heading and junk before I import it)
My Brain has completely lost all of it's gray matter.
I have two tables tbl_Employers and tbl_Services that are linked via a one to many relationship. Each Employer can have Many Services. The field i am useing in the relationship is EmployerID
If I build a simple select query using these tables I will see all of the employers that have a related record in the services table. Any employer could be listed there many times as per the relationship.
What i want is a simple count of how many employers actually have recieved a service.
Why is this so difficult for me to get my head around.
this is my query in design viewhttp://img99.imageshack.us/img99/3095/querytc3.th.gif (http://img99.imageshack.us/my.php?image=querytc3.gif)i use this query when entering datai want to know how i can set it up it display all or any one/two/none of the criteria i put into the question text boxes, number surname and state, or even just number, or just state.anyone?
