What is the best way to do this without losing data? I have several FK that I made the mistake of setting up as lookup fields. I now want to correct this without losing data if possible.
DataType currently says "Number" under each of these. So I can't just change them to number. Is there another way to do this?
I have imported 3 different excel worksheets into Access. I then created a query in which I made some relationships and select the fields that I need to make a new table. The problem is, when I run the table the final product is missing about 20,000 rows of data. I have used this protocol successfully for other other files, but for some reason, with this dataset Access is pasting 10,000 rows into the new table, where the original file has 39,000.

I was reading on MVPS.org, and found a page that denounces the use of lookup fields in tables, because of the way it skews relationships, weighing down the database.

Do you all agree with this?
What do you recommend I do, in lieu of lookup fields, when I need to maintain integrity of the data.
Thanks SO much. You guys are my heroes!

When I set up lookup fields that point to a table do I save those tables in the back end with the main tables or is it okay to have in in the front end and not the back end? Users will need to make udpates to the tables for instance an employee table they would need to add employee names.

I set the lookup for the last name and can see bothe first and last names in the drop down list. When I pick, I get the last name in the DonationT but how to I pick up the first name? That is, how do I fill DonorFirstName in DonationT from the FirstName field in the MemberT?
View 3 Replies View Relatedhow to do a particular thing in Access 2010 (I don't even know if it is possible).
I have a table named PRODUCTS:
ID_PRODUCT (primary key, autonumber long integer)
ALLOWED_OPTIONS (multi value text lookup field: "Option 1";"Option 2";...;"Option 9")
So I can store, for each different product, none, one, or more options to let the customers choose from.
I have a table named ORDERS:
ID_ORDER (primary key, autonumber long integer)
FK_CUSTOMER (foreign key, linked to the primary key of a CUSTOMERS table; represents the customer that places the order.)
FK_PRODUCT (foreign key, linked to PRODUCTS.ID_PRODUCT; represents the product that the customer has choosen)
CHOOSEN_OPTION (lookup text field; the customer must choose ONE option among those allowed for the product he has ordered)
The problem is that I would like the CHOOSEN_OPTION field to show as a combobox, listing the values stored into PRODUCTS.ALLOWED_OPTIONS, so that when a customer buys a product, he can choose only among the options allowed by that particular product.How can I manage a multi value field to populate a combobox, in which every item stays on its line? If I use, as a query to populate the combobox:
select [PRODUCTS].[ALLOWED_OPTIONS]
from PRODUCTS
where [PRODUCTS].[ID_PRODUCT]=[FK_PRODUCT]
I obtain an empty combobox.If I refer to the last field as [ORDERS].[FK_PRODUCT], Access asks me to type a value for "[ORDERS].[FK_PRODUCT]", treating it as an unknown parameter.I think that the problem is that when the combobox expands, the record is not committed yet, so FK_PRODUCT is unknown (NULL?). But this happens even if I commit the record typing something in FK_PRODUCT and then I re-enter the record and I expand the CHOOSEN_OPTION combobox, that is still empy although FK_PRODUCT exists, now.Is there a particular syntax to refer to a field in a record not committed yet (something like "THIS." or "ME.")?
I'm new to access and trying to figure out how to use a field to look up and return results from multiple tables. I've tried several books and also the northwind traders example. What i'm trying to do is just like the oder form in the orthwind traders example on the order form. I would like to insert the customer name via a combo box then have the address, phone etc. automatically update as well as automatically update the shipping address etc with the current billing address. I know this is pretty basic but I must me missing a step.
Thanks in advance

I have a table that contains about 75 fields. Each field is going to be a Lookup field that will allow the user to enter multiple values. This is for a home inspection service. So the first field name will be ExteriorShingles. The user clicks the dropdown arrow, and is allowed to select multiple values such as "loose", "missing", "rotted" etc... I was wondering if there is an easy way to import all these values from my Excel spreadsheet, or do I have to enter each one individually, which is going to be a lot of work.
View 2 Replies View RelatedI know experienced DB developers say never to use a lookup in a table for a foreign key and instead to use it on the form level. For this reason, I am going through my tables and removing lookups from the table level now.
But how do y'all feel about lookup value lists? (so the list is typed-in instead of looking up a table value)
If you think they shouldn't be used then what should I do instead? Should I make a table for the handful of values and link with a FK field?
Or is there a better way? I would rather not have to make a million tables for these short, stable value lists.
I created tables that have lookup fields referencing another field. Actually I have several tables that all have relationships and object dependencies in my database. Now that I am trying to create some different reports, when I run the report I get the ID rather than the contents of the field. Also, I have a 'Report Dashboard' so to speak that I can run different reports from. On the form I have Combo boxes that reference one of the tables. I can generate the report showing the information, however I tried using a text box (criteria)(=[Forms]![Reports Form]![Combo47]+" County") in the header of the report to reference the selection made in the form combo box. When I run the report I generate the ID in the header.how do I get rid of the lookup fields in the tables, or is there another work around?
View 5 Replies View RelatedIs there another field that can be used beside the lookup field in an Access table? I am currently using the lookup field as a multivalued lookup field and I am limited to the the things I can do with it when creating a report or a query on that field. Is there a similar field in Access 2010 that has the same look as a lookup field and allows for multiple values to be selected?
View 4 Replies View RelatedI have a database with various tables, customers, jobs_table, black_book. I am wanting to have a field that looks up a latest date.
Both the [jobs_table] and [black_book] have a date field, there can be multiple entries per customer in both fields. What I want to do is have 2 fields in the [customer] table that looks up the customer name in [jobs_table] and [black_book] and brings back the latest date.
My company had an Access db created back in 2002 in order to create file names (Legal Labeler). The db consists of many reference tables (Figure 1). The person who created the db created a form to use in order to create the file name and labels. As you can see there are various drop downs where the end user can choose which information to include. I do not think that the tables are linked. Once the end user fills in the form they click Save Label Data and the data is written to a master table (Table tblLevelOneSubject).
One of the problems we are having is that records in any one of the extraneous tables (Company Name, SubCatetory, SubCategories L1/L2, etc.) just disappear. For example, in Figure 3, we have all the entries for the drop down labeled SubCategory (A codes are depicted) but, for some reason, we are randomly missing some of the codes (typically all the A codes and B codes); however, nothing from the master table is missing (that is why I do not believe they are linked).
Another major issue we are running into is in the table named tblLevelFiveSubCatTwo (SubCategory L2 on the form) (Figure 4), which is an auto-numbered table, we are also losing records (as you can see it table starts at 7). When I created a file last week I needed to create a new entry in the drop down SubCategory L2 and it was auto-numbered 8 when it should have been 734. Also, the table shows that there are only 697 records but if we are auto-numbering there should be 734 records. Therefore, we are losing records in this table as well.
Is there any way we can secure the tables so this does not happen in the future? When I export the data into Excel it looks as though all of the data is accounted for - it is just missing in the reference tables.
I've developing a little Project and have some issues after splitting a db.
I have some forms in wich I want to see some tables with the "+" sign on the rows so I can go to their linked tables. The problem that I have is that everything works perfect until I split the access file.
I created a table in MS Access using a Lookup & Relationship data-type. This means that my record cells call upon a particular table for values. It creates a LIST of values for that cell.When I query a particular value in this table I get every possible combination of the value. My query and code are below:
OR,
SELECT MainT.Content.Value, MainT.Source, MainT.[Entities Impacted].Value, MainT.Update,
MainT.[Divisions Impacted].Value, MainT.Announced, MainT.Effective, MainT.Stakeholders.Value,
MainT.[Ref#ID], MainT.[Issuing Agencies].Value
FROM MainT
WHERE (((MainT.Content.Value) Like "*" & [Forms]![SearchF]![ContentCB] & "*" Or (MainT.Content.Value) Is Null)
[Code] .....
This means that if I query STATES: "California", I'll get back every possible combination that exists with the name California in that particular field.The issue with this is that I'll get MULTIPLE primary key values rather than just 1. So, if one record, under STATES has California in it, but the other fields in that record have the Lookup & Relationship data-type, then every possible combination of that record will query instead of the multiple field-values form that you'll see in the table I am querying.
notice that my primary key (REF#ID) is repeated numerous times! This obviously causes problems with generating records and forms concerning information for 1 particular primary key. Is there a way around this problem other than specifying search criteria down as much as possible?! Perhaps there is some SQL code.
I have a form and subform. Clicking a record in the subform displays the details of that record in the main form. The form is used for editing, adding and deleting data for a given person's sales record and the subform displays a full list of all records for that person.
When I edit a person's record, using the main form, and click on a button to run the code:
DoCmd.RunCommand acCmdSaveRecord
I can go into the underlying table and see the changes. I can also refresh the subform and see the changes.
However, the next time I click on any of the records in the subform, the value in one of the fields vanishes from both the subform and the table. Any other changes made, to however many fields, remain.
Surely, if there's a problem with that field, the update shouldn't happen at all?
I have problems understanding lookup tables, especially how to populate them with data. I'm working on an exams database, and have many such tables...
Table for Students
Table for Subjects
and a lookuptable for studentsubjects
Table for Classes 1, 2, 3, 4
Table for Subjects Eng, Math, Geo, Chem... 11 subjects in all
and a lookuptable SubjectClasses
Having inserted data for all subjects and all classes, should I then go ahead and Insert data for SubjectClasses? There will be 44 items!
Even more appalling, studentsubjects table will have (no of students * 11) for my small school, it will be 1,760

View 4 Replies View RelatedA field in a table can be populated by a lookup up but it has to be done manually or with a form.A "new" table can be created with a query that matches the data.

I am creating a table for data entry. Three fields in the table are going to be Firstname, Lastname, and Address. I want the choices for data entry to be read from a master table which contains first and last names and town of residence.
That being said I would like the choice of Lastname to be all last names from the master table, and the choices of Firstname to be those from the master table but are limited to having the Lastname as entered in the previous field, finally I want the Address field to be limited to those records which match the lastname and firstname. I have been playing around with lookup queries for each of the fields to no avail.
We have a lookup table that has a list of CLIN numbers and their costs. The contract that governs those CLIN numbers and costs will be changing to entirely new numbers. Unfortunately, I still need to have the old and new CLIN numbers linked to the other tables.
Will I need to merge all the CLIN numbers into one lookup table, or can I do it from two lookup tables?
Still not sure how to do this, after I convert my database and create an mde file few changes might accrue in the future, I have tried to make some changes for testing purpose and then create a new mde file and saved it with replacing the older one but I had lost my new data which was entered in the old mde file?
Q: how can I make the new change on my original file and not lose my new data in my mde file.
I'm wrestling with the issues; in other threads, it became apparent that because I could not know ahead of time what I will need to know about a given entity, I will use a table to enumerate attributes that is applicable for a given entity.
However, the stumper is that what if an attribute should conform to a set list of values? Since they are dynamic, I would have problem predicting what I will need to be able to lookup, and am even don't know whether I will need a one-many lookup or many-many lookup.
I thought that generic lookup table with a table listing "classes" of lookup would allow me to have one big generic lookup table while using "classes" to act like virtual tables so I can then set the query to appropriate "class" to return just right set of values.
But as I thought about it, I ran into some issues which is pulling me toward the crazy idea that I should have freestanding tables, and use a field in tblAttribute to give me the table's name so I'd know which free-standing table it points to, and have the necessary key to lookup the values within that table.
Even though my gut instincts tell me that I shouldn't be going against the conventions of database design (who the frick goes around creating free-standing lookups?!?), I'm simply not sure how I can use a generic lookup table to hold all information.
For example, suppose I was given a list of values that has its own categories. Since the former design allows only for two level (lookup and lookupclass), where am I to insert that extra level?
Furthermore, I found myself needing a set of virtual keys to reference a certain "class" of lookups for report purposes. That means I need an extra field in my lookup table than I originally anticipates. What if I find myself needing one more field that just won't fit the generic lookup table?
So does anyone have suggestions on how we would create a placeholder for a lookup table that will be made just in time?
Basically in my order details table i have the following fields
Product
Unit
Size
At the moment i have the Product field with a dropdown that gives me all the products from my ProductT. But once i choose the correct product in the unit field it gives me all the possibilities of every product not just the units associated with that product. ie
ProductT
Grasshopper Box1000 Adult
Grasshopper Box1000 Subadult
Worm 10pz Big
When I select the grasshopper product and move on to the unit field i also get "10pz" option but this is not a product available.
How do i set up validation of the fields Unit and size based on another fields data?
I have a table "Product" and in this table I have two fields "StoragePlaceID1" and "StoragePlaceID2". Both these fields link to the look-up table "StoragePlace"
*Attached Image "Product_StoragePlace" from the Access Relationship Window"*
When I want to add a new Product from my inter face i get the error you can see in the Attached Image "Save_Error".I think the problem is that the Relationship is defined as One-to-Many,there a way to define the relationship as Zero-to-Many.
Hello,
I wonder if anybody can help me.
I have a table called ITEM, within ITEM I have three fields ITEM NUMBER (Key Field), Item, Cost,
I have another table called INVOICE ITEMS, Within INVOICE ITEMS I have six Fields, INVOICE NUMBER, ITEM NUMBER, ITEM, UNIT COST, Amount, Total Amount.
I want to use Lookup wizard to complete the fields ITEM NUMBER, ITEM, UNIT COST from the ITEM table.
Is this possible?
