Access Massive Data Lookup
Sep 16, 2014
I have created a database with a list of product codes, pricing, costs, and supplier name. Now I have about 100 product codes which I would like to look up for all those information. Is there an effective way to do it in Access? I know I could export the whole datasheet to Excel to do a vLookup, but it may be lots of waiting time if the data are massive.

I am trying replicate the northwind web database macro called getproductname getproductlist which is on the products table. this macro has a simple lookup action which looks up a record by a parameter being sent.
the customer order form has a productid combo box. on its after update it finds the product list. this UI macro just passess the product id to the data macro on the table and looks up the price for that id. then sets the value on the form. simple right? however i consistently get an error from the data macro on the table which says the "the identifier (enter field name here) could not be found"
in my case im selecting id and productname from my table. the syntax is correct. but when i run the macro i get "the identifier productname could not be found. ive been struggling with this for hours. and im using a working sample as an example.

I want to create a Web App in Access 2013 that contains a table of client names, addresses etc, and a second table that contains order details, including client name. It would be nice to ensure that as someone adds a new order they are give a drop down menu containing existing client names, and I can see how you can do this for a brand new table using the lookup data type. But I already have an Excel spread sheet containing client names. If I import this into my Access web app to create the client table, and import the existing orders to create the order table, I then try and change the data type of the client name (in the order table) from short text to lookup, it won't let me!! (If I create an empty client table from scratch, it lets me define the company name as a lookup data type - but I can't then import from Excel into this empty table)

I need to select the last 20 records from a databse that have over 1.25 MILLION records.
Obviously the usual stuff like order by is breaking the server with buffer issues.
Anybody any ideas of how to get around this?

Hi, it's me again, the guy who works with the Amusement ride industry. I'm trying to set up a way to ogranize all our saftey bulletins that we get.
I've already looked into indexing but the major problem is that the user will need to be able to search on multiple criteria (for example the Tilt A Whirl was made by three different manufacturers). Also I can't download that nifty google tool bar because we're running win 2000 without service pac 3.
Access seemed like a great alernative, but I have about 300 or so files I need to link. Is there a faster way of linking these files than going through and doing them one by one?
I have a pre-made index the guy before me made in exel. Most all the files are in PDF format if it helps at all.
Thanks.

Hi, i'm new here and I know there's a lot going on but i was hoping someone could point me in the right direction or give me a few tips...
I've imported a very large (nearly 15000 records) set of data into an Access database as one big huge table storing various bits of information about coins. As far as I can tell, the data is in at least first normal form, in that no multiple values are stored in any columns (not yet sure of the technical term - field?)
Anyway, I've managed to use a make table query to separate out some of the content of the table into separate tables with relating entities.
One question is, and please bear with me - How do I add an autonumbered primary key to these newly separated out tables and then add these autonumbered items to the original tables as IDs so that I can set up relationships? Is there a "proper" way to go about describing this?
The following consists of ALL the fields in the original table and how i've split them up by table:
STOCK
Group
ItemNo
ListNo
TypeCode
ActualDate
SortDate
CostPrice
SalePrice
Estimate
StockLevel
DateEntered
DateSold
Archived
Ref1
Ref2
Picture
Description
Cats
DenomCode
TypeCode
PeriodCode
ArchiveWhenSold
NotForSale
KeepSold
StockItem
Highlight
OnLists
OnWeb
Proof
DENOMINATIONS
DenomName
DenomCode
DenomHeading
DenomValue
PERIODS
PeriodName
PeriodCode
PeriodHeading
PeriodStartYear
PeriodEndYear
VARIETIES
Variety
The Variety field in the Variety table is especially problematic. There were 1259 varieties stored in the original table which are now in a separate Varieties table which is great. But how do i now add an autoincrement number and call it, say, VarietyID, but then link each Variety back to the main list of coins but replace the full Variety description with the newly created VarietyID?
If any of that made sense, i'd REALLY appreciate some wisdom here.
Thanks

Is there a way to disable the filter feature in MS Access? I have several users that use the filter to find a single record when I've repeatedly told them that using CTRL-F is faster and less of a strain on network traffic.
I'm trying to eliminate all possible causes of a massive slowdown that occurs everyday at roughly 10-noon. There are several ODBC timeouts (even after including some code to have it attempt to retrieve the data 3 times prior to it allowing the timeout message to pop-up).
I have removed all linked tables/queries that are not needed and the database has been rebuilt. Compressed the database is under 2 megs and the SQL Server backend is on it's own server where the same queries return instant results.

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.")?

Hi Folks
I have a form that is based on a query.
I want to change the unique ID that is displayed on this form.
The new ID is sourced from a different query. I.E. Not the same query that the form derives its information.
I have set the data source property of the field (Combo1) to the "other" query.
How do I get the Combo1 to update to the value of the first record?
Currently its defaulting to Null.
I have tried using :
Me.Combo1.Requery - This does NOTHING to the vaue.
Me.Combo1.MoveNext - I keep getting a "Method or data members not found" error.

Heres something I dont understand about the lookup wizard:
Ive done a lookup wizard on one of my fields, so that now the user gets a drop down list of options to choose from:
0;1;2;3;4;5;6;7;8;"NTSC";"PAL"
Ive also set "Limit to list" to yes, so that these are the only options the user can enter.
However, it will still let me change and play around with the data type settings under the general tab. I dont understand why it lets me do this. I can set the lookup to the above list, and then specify a date type of type "date", and it will allow me to do it.
Why is this the case? Which datatype should I set it to, if I have a list of values like the one above?

This is going to sound really stupid but I urgently need to have one form, where people can enter a product code and the description automatically shows in another field.
I have two tables, one for the form and another with all product codes and descriptions.
Presumaby I would need to make a query, which i've tried and failed miserably.
it seems so simple when you read the access help but i've missed something fundamental.
HELP!
Thank you.
PS I should have said my boss expects to enter data in one field - the product code - and the description automatically and instantly pops up in another field on the same form before leaving that particular record.

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.

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?
Thanks in advance.

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

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?

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.

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?

manipulate the data by changing one of the columns (Customer 1) to a Look Up Field. This has created two challenges for myself:
1) The data is gone ... oops. I can solve this one.
2) More serious, that column (Customer 1) will only display primary key numbers of the data. Before the corruption, I had a combo box on a form. This combo box took its values from a Table called CustomerTable, the value in this combo box was stored in the QuoteListTable. Before it showed names, now only primary key.
I have attempted to:
-change the look-up back to a regular field (got rid of the look-up)
-exported the table to a query, turned it back into a table, no change.

Hey there,
I am wondering if there is somekind of tool that can be used in access that can run and locate any queries that are redundant and not used within a system. Also if there is any kind of tool that can be run that identifies fields that are in tables that are also not used in the application!
Not sure if such software exists but thought id ask before i manually begin to go through the application, this is all done to be done before normalisation of the application data and upgrade of the system
Thanks in advance

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 got a a form storing all employee's information and on that form I have a lookup field which looks up all the records in the "Qualification table" and the user can select multple qualifications. What I want to add to the lookup field is a data box so you can select a qualification and then enter the date that it expires (different for expiry date for each employee) How do I do this?
I have added the date field to the qualification table but when I create the lookup field on the form it shows the qualifications and a blank column next to it which data can't be enteed into.
