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 have three large source tables imported into my database. I have created queries to retrieve relevant values from fields in each source table which feeds into my form. Each field on my form that is connected to the relevant query is a lookup field. For example, one field called "Supplier_Name" another called "Supplier_Code" and a third called "Route_Number".
Needless to say each of my lookup fields are very long. I am trying to filter my search based upon the selection from the previous Lookup field. How I can filter a lookup field's value based upon the previous lookup field selection? Each Supplier has a code and assign route(s) and I have already established these relationships.
I was looking for some help. I am trying to setup a table with a field for web address. People are entering www.website.com etc however I need them to make sure it starts with http:// Is their any way I can put validation on the field to make sure that this is entered? Or maybe I could use an input mask?
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 Invoice & Address file I want to know how I can for example enter customer number in the Invoice file and get the information form Address file in the Invoice file.
Hi all Im trying to create a database where one field has a lookup to another field in another table (easy enough done) the the next field in the first table has another lookup, however the items the user can select change dependent on what was selected in the first feild eg: SelectA -A1 -A2 SelectB -B1 -B2 So the user can only select B1 in the second field if SelectB was picked in the first field
I wonder if anyone can help. I have 2 tables. Table1 (lookup table)has 2 fields: 'rate' and a 'minimum amount'. The rate applies to a range of values eg up to 1000,rate=20, up to 5000, rate = 22 etc. Table 2 has 3 fields: 'UniqueID', 'current_rate', 'amount'. The 'amount' field in table 2 increases on a monthly basis and when this reaches the next amount threshold (in Table1), the 'current_rate' needs to be updated in table 2 to the appropriate value. I have searched this forum and Dlookup seems looks to be the only way to do it. However, I think this only returns one result and some of the suggested solutions use a form to input the 'amount', when I have many entries that need to be updated. Any suggestions would be appreciated.
i'm sure this must be pretty simple but when i search for lookup i keep finding stuff about translating names into numeric id's which is not what i mean
what i have is a table TBL_EnergySavings with these fields
IDFuel, IDProperty, IDMeasure, EnergySaving
its a lookup table so that given the three ID numbers (of a type of energy saving measure like loft insulation, installed in a certain type of property which uses a certain type of fuel) we can say how much energy is typically saved in GWhrs
I have another table of installed measures (jobs) which has property type, fuel type and measure type amongst its fields and what i need to do is to fill in a column in that table with the energy saved by each measure
so how do i look up the relavant record from TBL_EnergySavings?
Hi, im fairly new to access. im creating my 2nd access project for my 2nd year of A levels and i need a bit of help with lookups on a form im using
heres a screenshot of the form

What i want is for when you select an option from the category combo box, for the sub category to have limited options. Example: i choose Drinks from the main category combo, the sub category combo will only have a list of types of drinks available.
This has probably been posted before, but to be honest i didnt know what to search for.
I have a form which is used to enter contact details into my database. This includes the organisation for which each contact works. We have quite a few contacts from each organisation.
To ensure that the organisation name is always entered exactly the same, I'd like to use a lookup box which allows the user to choose the organisation if it's already in the system, or to enter it if it's new and not already there.
Is it possible to have a lookup box which shows the values already entered in the field to which the input will be stored?
It's supposed to be a form for adding a new booking to a table.
Now there's one table with vessels and a different one with lines/deadlines.
Every vessel is on a line that has a certain deadline.
My question: Is it possible for a user to select the vessel from a list on the form, having the form automatically look up the deadline and showing this in a different part of the form.
The meaning is to add a new booking with vessel and deadline into one table...
Don't know if my story is understandble, if not, please ask me to clarify...
I have a user options form linked to a table. The table is just one record with an option group on the form. the user selects which report template they'd like to use. the user closes the form down and resumes normal data entry.
when it comes time to represent the data in a report, i'd like it to display according to the template type the user selected in the options form. I have 3 different report templates. They all say the same thing... one is just prettier than the other!! Users like to customise!!
in effect, i'd like the database to check which report template has been selected from the options table, then open the appropriate report.
It sounds kinda simple but i can't quite figure the code. I think i need to use a lookup statement somewhere.
I want to put a lookup box on my switchboard where I can type in Company Name and automatically open up the form in the correct Company. I have tried to do this through a query but this just brings up a full-list, also tried a macro but this wouldn't work. Can anyone help please?
I would like to create a look up for a field from a table - that displays the OfficeID and the officename when it pops up, but only store the value of the id in the table.
OfficeID officename 1 Office 1 2 Office 2
My lookup Row Source is:
Code:SELECT office.OfficeID, office.officename FROM office ORDER BY office.officename;
Only the OfficeID seems to show in the lookup.
How would I get both to show, but only the OfficeID to be put into the field?

The following SQL query is returning no records when I know for a fact there are some there! Can anyone please hlp me?!
Dim strSQL As String strSQL = "SELECT * FROM tblHirer WHERE HirerSurname= 'Forms!frmFinanceProposal!Child845!Text430'" rsFindDuplicates.Open strSQL, CurrentProject.Connection, adOpenKeyset, adLockOptimistic rsFindDuplicates.RecordCount
Also, I was wondering how I would put as 2nd filter on the recordset to equal a particular date?
SELECT Institutions.*, Institutions.merge, Institutions.Inst_type FROM Institutions WHERE (((Institutions.merge)=True) AND ((Institutions.Inst_type)=[forms]![merge_inst_type]![Inst_type]));
and I had a command button which process
MergeAllWord ("select * from merge_query_true")
but I am getting an error like this "make sure the sql is correct , sql was select * from merge_query_true
select * from merge_query_true ---- is this code ok?
If I had cut the part "AND ((Institutions.Inst_type)=[forms]![merge_inst_type]![Inst_type])); from the sql it works fine....
i need to be able to use "lookup", i have a set of postcodes from 3000 customers, i need to extract these and compare them to lists i have of postcodes, which make up a region. And run queries from these
e.g a customer on my database has the postcode BD21 7KK
On my list of postcodes i have on paper - WEST YORKSHIRE - BD21 7
therefore The BD21 7KK Customer falls in the West Yorkshire region.
I need to do this four 4 regions with lists i have on paper then run queries.
Can some one please provide the neccessary steps?
Or even give me an example made?
Im really stuck on this at the moment and me job depends on it ! :(
