Relationship Issue? I Need Some Assitance From The Experts On This One.
Jan 6, 2006
Forms used:
frmAnnualService
frmPostCardback
Tables used:
tblAnnualService
tblCustomers
I have a database created containing 2 tables. (tblAnnualService and tblCustomers). I have the Repair Order set as the primary key in both tables since it should never have a duplicate. I have a one to one relationship, enforce referential integrity and I have cascade updated related fields. The join type I chose is 3. Include ALL records from tblCustomers and only those records from tblAnnualService where joined fields are equal.
I have a couple issues ongoing at the moment. I have a button on the master form (frmAnnualService) used to input service information for each customer. This button runs and update query that updates tblAnnualService and all fields on this form are bound back to tblAnnualService.
With the setting on the relationship as listed above neither one of the tables is being updated. When I change my relationship and remove enforce referential integrity and cascade updated fields, change join type to 1. Change only include rows where joined fields from both tables are the same the tblAnnualService updates but the tblCustomers does not.
I have another form (a postcard mailer frmPostCardback) that is bound to the tblCustomers. I need to be able to from the frmAnnualService input the data, click the update query table button and have it update the tblAnnualService and the tblCustomers. I assume I do not have my relationship setup correctly. Can someone please assist? I some background with Access but need your comments to be specific and detailed so I can make sure I am correcting the issue properly.
Thanks in advance for any assistance I receive.

I have the following code that will import OLE objects into access, and it works quite well...but, how do I get it to check to see if a reocrd already exists and not to duplicate a reocrd? I am not a programmer, I have a couple of ideals but I don't know where to start. Any help would be appreciated.
If I were to put a new file into the folder, I would like the code to only import the new file and all files again. Which currently it will just create new reocrds for the existing document. I hope I have explained this... Any help would be appreciated. Thanks. vb Code: Original - vb Code Private Sub cmdLoadOLE_Click() Dim MyFolder As String Dim MyExt As String Dim MyPath As String Dim MyFile As String Dim strCriteria As String MyFolder = Me!SearchFolder ' Get the search path. MyPath = MyFolder & "" & "*." & [SearchExtension] ' Get the first file in the path containing the file extension. MyFile = Dir(MyPath, vbNormal) Do While Len(MyFile) <> 0 [OLEpath] = MyFolder & "" & MyFile [OLEFile].Class = [OLEClass] [OLEFile].OLETypeAllowed = acOLEEmbedded [OLEFile].SourceDoc = [OLEpath] [OLEFile].Action = acOLECreateEmbed ' Check for next OLE file in the folder. MyFile = Dir DoCmd.RunCommand acCmdRecordsGoToNew LoopEnd Sub Private Sub cmdLoadOLE_Click() Dim MyFolder As String Dim MyExt As String Dim MyPath As String Dim MyFile As String Dim strCriteria As String MyFolder = Me!SearchFolder ' Get the search path. MyPath = MyFolder & "" & "*." & [SearchExtension] ' Get the first file in the path containing the file extension.

MyFile = Dir DoCmd.RunCommand acCmdRecordsGoToNew Loop End Sub

I have a very large database with record that are from 3 to 11 characters long. I would like to run a query to inset dashes at position 5 and 9 so a part number would look like this 0000-000-0000 or following the same convention but never dashes as the last character
this is what i currently have
UPDATE stihl SET [part number] = left([part number], 4)& "-" & mid ([part number], 5);
then run a second as follows
UPDATE stihl SET [part number] = left([part number], 8)& "-" & mid ([part number], 9);
the problem this adds dashes after numbers shorter than 11 and 2 dashes if on 4 long.
Any ideas thanks in advance

I need to complete a project for school for my computer class. I am having some problems with this one assignment. I am finished but want to know if anybody can help me. Just verify that the answer is right or wrong. Any input will be greatly appreciated. Here it is... Its just a fill in the blank so if anybody who knows MS access can help me that would be great. Thanks.
The word required are the ones with the underscores around them.
Fill in the blanks:
1. Some developers like to use the _Design View_ property for a field to document its contents, such as identifying a field as a primary or foreign key or providing users with instructions about entering values into the field.
2. A _Query__ is a database object that stores criteria for selecting records from one or more tables based on conditions you specify.
3. To select multiple controls, you could click a control, and then press and hold the _Shift_ key and then click the addition controls you want to select, releasing the key once all the controls are selected.
4. A form?s _Table_ is the underlying object that provides the fields and data in the form.
5. You can view a description of each property in a property sheet by clicking the property and then pressing the _F1_ key.
6. When you select a control, eight handles appear on its corners and edges. The larger handle in a control?s upper-left corner is its _Move_ handle.
7. A(n) _Data Type_ displays a list of values, and lets users select one from the list.
8. Each report can have up to _Over 300_ sort fields.
9. An advantage of using the _Table Wizard_ to create a table is that the sample tables and fields already have properties set that might work well in your database or that are easily changed to accommodate your specific data needs.
10. In Design view, you can use the _Property Sheet_ to set the properties for fields that do not use the default settings.
11. In Access, you can specify restrictions on the data that users can enter into a field by creating a(n) _Validation Rule.
12. If a user attempts to enter an invalid value in a field, the _Validation Text_ property for the field opens a dialog box with a predefined message that explains the valid values.
13. In Access, you define table relationships in the _Relationship_ window.
14. You use _Borders_ around field names to distinguish them from function names or other types of values.
15. When entering the data in a table in Datasheet view, you would press the _Control + Minus Sign_ key to cancel a record that you have just entered.
16. In Access, you can control the format of a value by creating a(n) _Input Mask_.
17. A(n) _Look Up_ field lets the user select a field value from a list of existing field values stored in the database or from a list of values specified when the field was created.
18. The primary objective of creating a(n) _Indexed_ field in a table is to prevent users from entering duplicate records into the table.
19. If an expression is complex, you can use _Brackets_ to indicate which operation should be performed first.
20. To move from one record to another in a main form, you would click the buttons on the _Navigation_ bar at the bottom of the main form.

I am new to access, so I haven't been able to come up to speed on all of the functionalities that it has. I have a table with a social security number, an effective date, a department, and pay periods. I have seven other tables with a social, a date, and absentee occurances. For any social in the seven tables, I need to subtract one pay period from the original pay period table based upon the max effective date that is less than the occurance date. I am dealing with large amounts of data, at least a million rows in the original table, and 50,000 in the 7 smaller tables. I know access may not be ideal for this solution, but it is what I have to work with. Any suggestions?

Dear Access Chart Expert
I have been trying to figure out how I can make the x-axis show month abbreviation names instead of numbers. Please see attached gif.
Currently, I use the Month([DateField]) function to get numbers of the month because if I use Format([DateField], "mmm") to get "Jan, Feb, March" the chart sorts the months in alphabetical order instead of the correct monthly order.
How can I be able to use the Jan, Feb etc... labels and have the chart sort them in the correct month order and not alphabetical order?
Thanks so much...
greatly appreciated.

Ok guys, I've been eyeing this problem since June and I must say that I'm rather sick of it. After months of dredging the web, I've come to the find multiple mocking hits implying that the answer may lay somewhere in the Experts-Exchange, where i understand that some of you have been know to roam.
Without furthur blather, I must admit that im trying to avoid paying 12 bucks for this answer, especially as I've grown suspicious that this is a straight up MS/Adobe collaboration failure... and now for the problem.
When opening PDF files from my database (Access 2003) Acrobat (7 and 8) successfully opens the pdf. When I attempt close the PDF, nothing happens and I get the following Error when i go back to access:
The operation on the Acrobat Document object failed.
The OLE Server may not be registered
To register the OLE Server, reinstall it.
Hit Ok and the PDF file closes. ANNOYING AS H#LL.
I have repaired access, and acrobat. I have reinstalled. I have checked registries. I have updated .dll's. The only help I can offer is that when opened on an IT guys computer the problem seems to be gone. I'd bet this is because he has a pro copy of adobe. Basically I'm trying to figure out if i need to convince the powers that be to put a copy of Pro on any computer using the DB (if thats whats really helped), or if there is still some way I can fix this myself. Thanks gentlefolk! You (plural) are the rule.

I Need to eliminate repeat entries of Names in a Combo pull down list
I have since found out that this is possible with the DISTINCT directive in a simple query like
SELECT DISTINCT [Name] FROM Miracle_Cloth_Main ORDER BY [Name] DESC; as the source
property of the combo box.
It looks like ACCESS needs A primary Key included in the querry for the source property
of the combo for the FindFirst function in the after_update event of the combobox
to work with a code similar to
rs.FindFirst "[RecordNum] = " & Str(Nz(Me![Combo112], 0))
The Wizard generate the following code even if you don't select the Primary Key(RecordNum)
during the creation process.
SELECT Miracle_Cloth_Main.RecordNum, Miracle_Cloth_Main.Name, Miracle_Cloth_Main.Cust_ID FROM Miracle_Cloth_Main ORDER BY [Cust_ID] DESC;
Even if you add the DISTINCT Cluse to the above code
it doesn't filter the repeat data.
Is there a compromise where I can get the Filtering by DISTINCT clause to work with the code generated by the wizard so that I get the FindFirst function as well to work ?

Hi there,
I'm creating a database for my computer repair business and it's going to store details on my customers, their computers, and any repairs I carry out on them.
I've created some tables, but I'm unable to create the relationships I require between the tables. Here's what I have:
http://img352.imageshack.us/img352/4724/helpbk3.jpg
I want to create a one-to-many relationship between the tables left to right, excluding the Engineer table, which I will talk about in a moment.
The idea is - One customer has "many" computers, one computer has "many" repairs, one repair has "many" problems. Each repair has just ONE engineer assigned to it, although the engineer will be assigned to many repairs.
I can link the Customer and Computer tables, via the CustomerID, but when I try to connect the other tables, I get the "Relationship Type: Indeterminate" error.
Can anyone help me with what fields I need in each table, and what relationships I need to achieve what I need?
Many thanks :)
Paul

My friends,
I am trying as hard as I can to learn Access. I am developing a database for my signage design business. I've been at it for about 5 days already. I know this question would be a piece of cake for the experts in this forum.
When one of my artists finishes with an artwork, he will save this as a jpeg file. I want him to upload it to the database via a form.
1. I would like to come up with a command button that, when clicked, will open a browser on the users remote computer and enables him to find the file to upload.
2. When this file uploads, I want it to be saved in another directory, outside the db, and then linked to a field within the db.
3. And I want this feature also for mp3 files.
Can any one help with this?

Hi All,
I am new to access and this forum, so hello all.
I am trying to build a database to keep records of my bird sightings. As you might have surmised; I am a birder.
I have come to a holt on creating a complex relationship between the Bird Entry From and the table that contains a list of British birds.
In Bird Entry From two of the fields are for entry of the bird name, one field being the Common Name and the other being the Latin Name. They are both drop down lists that contain all the birds from the table, this being done by import data. The table that holds the bird list has two fields One is called Common Name and the other is called Latin Name, this being the same as the filed names in question in the Bird Entry From
This is where I am coming unstuck. What I would like to happen is that when I enter a bird in the Common Name field (either by typing until the bird is auto entered from the drop down or using the drop down to find the bird) it automatically enters the Latin name in the Latin Name field and visa-versa, but I have become very frustrated with trying to do this.
Am I wasting my time? Or is it possible? And if so would anyone be kind enough to tell me how?
Many thanks,
Simon.

As you all know Im not a expert on databases but work in a volunteer basis in a small community area where we have no money for people to do anything for us.
Im proud because I did the other database and its up and working but this one has got me beat.
Im setting up one for the volunteers, which has computer knowledge, any basic training they need, when they are available and what tasks have been set for them.
I need to have a one form which has just their personal details but to be able to put in data on the other forms and it will link back to the volunteers name.
Ive attached what Ive done and Im sure your all going to laugh - but any help would be appreciated

Trying to set up a fairly simple DB. Here is the layout:
tblRoom(roomID, roomNumber, rackOne, rackTwo, rackThree)
tblStudent(studentID, name)
Each student will be assigned to one, and only one, rack. There will be 3 students to one room. One student can only have one room but a room can have many students... I store studentID in the rackOne, Two and Three fields. My problem is when I try and querry for the information so as to display actual names rather than ID's. I'm not sure If my querry is the problem or if I've set the tables up incorrectly. Any insight is much appreciated.

Any ideas?

at one point in my database I have two tables and for everyone record in one table I may have either 1 or 0 records in the other. How do I express this in access design? Since it's an optional 1 to 1 relationship I guess?

I was wondering if anyone could help me with a query. Basically I am doing (or trying to do) a small database to track childrens progress in my mums primary school. I'm doing this for free as the budget is rubbish for this type of thing and i dont have enough knowledge to ask for payment anyway! I want to get it right from the start and I think if I get the relationships right initially then I can complete the rest of it on my own. I did this at university (normalisation etc) but ive not used it since i left in 2002 and so have practically forgotten everything i ever did.
Basically, the child comes into the school and is predicted a level in maths, reading and writing. Then in the october, feb and july of each of the 2 years they are there, they are given actual assessment levels. They are also given a prediction level at the beginning of year 2.
So far I have one table with student no, surname, first name, gender, ethnicity, year group and SEN(special educational needs) - with the primary key being student no.
This is where I get stuck - do I go for a maths, reading and writing tables and split it that way - or on an assessment basis, so prediction yr1, october yr1, feb yr 1 etc etc. Or is this completely wrong? Am sooooo confused, so any help would be greatly appreciated.
The outcome I want is to be able to query a childs progress, so for example: show children who achieved a 1a in yr1 maths, and then out of those children, who achieved a 2a in y2 maths (as this is the required shift in progress set by government). I really hope that makes sense.
Thanks in advance

I'm rebuilding my database from scratch now that I've learned a bit from the forums about developing a proper database and I want to investigate whether I have the relationships set up correctly, as I seem to be using lot of one-to-one relationship, which most articles say is very rare, and whether I am formulating many to many relationship correctly. Here is a screenshot of my relationship.
If I've understood this correctly, one-on-one is desired if you have a subset of data that is applicable to the main table only occasionally and is dependent on the main table's data. Have I used that correctly?
As for many to many relationship, articles say this is formed by having two one to many relationship linked together in a table. In my screenshot, you can see that tblAdvocacyVisit is the linking table. However, I've set GuestID as a one-one relationship whereas ClientID is one to many relationship, reasoning that since I do need to relate the Guestl Logbook data to Advocacy table for some queries I will be performing later, this will save me some work. I'm afraid that this may compromise RI or something like that. I can simply add a PK autonumber to tblAdvocacy to revert the GuestID as a one-many relationship, but can't see how that would not create more work in queries or so...
Oh, are the lookup tables supposed to be related at all?
TIA.
Edit- Updated the relationship screenshot.

I’m building a database of protein mutants we use in the lab. A lot of analysis is done on these proteins by various people and it’s becoming a bit of a nightmare keeping track of all the information per protein. What we need is a database. I’m getting a reasonable grip on it all I think with the excellent examples I have found on the forum but there are obviously areas that I have great difficulty with. The main problem for now is that many-to-many relationships are involved and I just cannot get them to work properly.
On each protein up to 8 different types of test are performed. To keep things easy I’ll call them A1 (for Analysis1), A2, A3 etc. These are done by different people from a group of 7. I’ve called them O1 (Operator1), O2, O3 etc. Each of the operators can do multiple analysis and the operators overlap. So e.g. O1 might be particularly good at A1, A4 and A7, O2 might be good at A2, A4 and A5, and O3 predominantly does A1, A4 and A6. What it comes down to is that each operator can in principle do each of the analysis so I have to give that option in the database.
What does work (but is not the solution as it introduces 8x duplication of data) is if I have a separate table with operators for each analysis. The same tblOperators is linked 8 times. There must be a way to link each of the analyis to only 1 tblOperators, probably with the use of a linking but I just cannot work it out from the examples I've found here.
Can someone help me on my way please?
Thanks,
Walter

New guy on the block here.
I am having trouble associating the relationships within a database to accomplish what I need. I don't know if I am over thinking or I just plain old don't get it. So, I ask if someone can draft this database up rather easily and post it for me or send me in the right direction to learn quickly.
This is what I am looking for: A table with people’s first name, last name, title, job position. That is it. I can do that and have done that. No problems.
Another table that has amplifying data on that person such as: date of birth, SSN, date employed, comments, etc.
What I envision is, creating a form to add the names, title, and job position of the people to the table.
Then I want to create another form that puts the other data associated with that person. This other form should have the first and last name from the first record to "view" only so the correct data can be added to the correct person.
That is it; I hope someone can help me out. I have been working on this for sometime and just can't seem to get it.
Thanks, all, E-dub
