Tables :: How To Switch Lookup Table To New One And Preserve Old Data
Oct 17, 2013
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?
A 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.
Is it possible to skip these steps and create a field that automatically populates with the data from another table based on other common data?I can do this in Excel but not sure it can be done in Access.
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.
This is a CSV file that comes through an Access specification. I need to be able to copy the items from the table to other tables but somehow apply a unique and sequential ID to the rows first, this is essential to the job. The text import spec applies a unique ID but save the spec, and call it using VBA, it doesn't do that.
Also, there seems to be a bug where using a macro to run the text import specification, (and this is after an update from Microsoft), that it doesn't recognize the specs anymore... after I deleted several of them.
how 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 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.
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 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.
I have several tables which have an indexed, no dup field. When inputting a entry that is not in the referenced table, how can I be taken directly to the input form for that field.
I 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've designed a database at work to collate information about locations around the world that are contaminated by conflict and military activities. I'm struggling with the use of the lookup wizard to populate some fields in one table from another table.The database is ultimately meant to be used to identify contaminated sites in various countries and also to be a source of data for an online interactive map. As such, it needs to hold a fair amount of information. I figured that it would be normal that some fields and tables would be connected to one another. So, for example:
Country table is looked up by the conflict table to provide the names of countries participating in a conflict. To do so I used the lookup wizard. Similarly, the Site information table is looked up by the Site contamination event table to provide the names of contaminated sites. The Site contamination event table. Then the Site assessment table looks up the Site contamination event table to provide the name of contaminated sites. The relationship between these three table is intended so that at any given site multiple instances of contamination and their subsequent assessment can be recorded. This is where I started noticing problems. When I tried to input some fields into the Site assessment table, specifically the 'Site name', it would only display the primary and foreign keys in the drop down menu but not the 'Site name'.
- Have I messed up by relying on the lookup wizard in my table design? This seems to be the consensus in this and most forums (I checked another thread in the 'Tables' forum here). That said, I've seen some people making a distinction between using 'Lookup tables' and 'Lookup fields within a table', but given my relative newbyness I'm struggling to see the difference!
- If the answer is yes then what approach should I take to achieve the same aim (having multiple tables that feed information to one another). Initial research seems to suggest putting lookup/combo boxes in my forms. I'm dabbling with that at the minute but so far the results haven't been as desired.
I've attached a zip file with a screenshot of my relationships diagram to give an extra idea. Note that the relationship between the 'Site assessment' table and 'Site contamination event' table isn't showing up as I removed while trying to troubleshoot, but it is supposed to be one-to-many from 'Site contamination event' to 'Site assessment'.
I have a front-end/back-end database that another programmer has done some work on for me. He worked on his own copy which wasn't linked to our data. Now I'm ready to integrate his work. What I would like to do is take his improved front-end and link it to the existing back-end tables. All the table names are the same, and none of the fields have changed. Is there an easy way to do this?
When designing a table I've created a field and set its lookup properties to display a combobox with a row source that returns a DISTINCT set of values already entered into the field.
After a row insert or row update the combobox needs to be required to ensure its list is complete.
If I create a form to display my datasheet this is easy. But I'd prefer to enter data directly into the table datasheet directly. I need to enter simple data into about 20 different tables and I'd prefer not to create 20 forms unless it's really necessary.
The lookup wizard generated entries similar to those I'd previously created manually, except the wizard generated a couple of extra settings that appeared briefly that were not part of the regular set of lookup tab properties. These additional settings referred to 'update propagation'. Once they'd disappeared I couldn't see any way to get them back..
The quantity band currently is fixed to 5 bands but would need to be flexible. There are also 2 prices for each of the quantity band (normal/special)
At the moment my table design looks like this:
ID fkSupplierID fkProductGroupID txtLayers (value list) intMinQty intMaxQty curNormalPrice curSpecialPrice
This works quite well with the query to return price based on product group, layer and order qty. However I am not very sure if this is the best way to design this. I am just thinking about maintenance - for example when the supplier puts in a price change or when the quantity band changes. The current format (quantity band) is based on a major supplier but in the future we would like to adopt this for any supplier.
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?
I'm making a database to track projects/opportunities. I have a Project Data table, a customer table, and a contact table. A customer can have multiple contacts. I have already figured out how to use a lookup in the Project Data table to be able to select a customer for the project but how do I then select a contact based on that customer? I want to be able to assign a "main contact" in the project data table based on the customer that is selected.how to use the customer selected in the project data table to provide only the contacts for that customer to be selected from a combo box in the project data table.
i have a user permission table.that consists of PermissionPK, UserFK, CompanyFK. I also want the username to be automatically filled in?So when a user ID is filled in on the table, it also fills in what that UserID's Username should be?As i need both the UserId and Username text for code that looks at the Environ username.
Okay, for simplicity's sake, I have a data entry form.
It is bound to tableData.
Inputs are:
ProductID Customer Name
ProductID is a combo box.
There is another table called tableProduct. In this table, is ProductID and ProductName.
For convenience sake, when a user chooses a ProductID from the combo box, I want it to lookup that ID from tableProduct. However, how can I do this when everything is already bound to tableData?

ProductID is a combo box on the form.

For convenience sake, when a user chooses a ProductID from the combo box, I want a separate textbox to lookup that ID from tableProduct and display the ProductName.
I have a split database and need a field (Combo type) in the table to lookup values from a query in the front end. How do I do this as it doesn't see the querys because the front and back end are split?
how data is best structured in Access.I have a table of values (for instance: weight) and I need to be able to look up a weight based on the column header (age) and row header (height).How is this sort of data best structured and accessed in Access?
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.
