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 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.
Apologies - i'm a "rookie" at Access - but i have searched for a while now on the site for the answer to my question... I'm sure there is a simple solution somwhere here but i cant find it!
I am putting togther an venue database - with all the usual fields: Name, Address, Capacity etc... of which i have set up YES/NO, Free Text and Number fields. No problem!
I have also set up various lookup lists which work fine, apart form the venue "Suitability" lookup list.
The choices are:
Corporate Private Drinks Reception Dry Hire Music Event Conference
Now, some venues may be suitable for SEVERAL of these uses - so how do i select multiple uses from this list as opposed to just one?
Many thanks in advance for your help - im learning fast! :rolleyes:
Have simple continuous form to create a pick list. One combo field looks up products from a list of about 5000 items.
Even though the combo homes in as letters are typed there is still a lot of typing needed to identify the target product. This is because many products have the same 10 to 15 characters to start, then have different endings.
It would be great if in adding a new item the combo remembered what was typed in the previous entry, as the picklist is built alphabetically.
Hi, all! I'm once again needing your sage, wise advice.
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.
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 have a member table and donation table. For a donation, I'd like to lookup the last and first names from the member table. 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?
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.
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.
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 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?
Is 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?
I 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.
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.
I am developing a database for a school and I have a form for staff addresses where the city is a drop down box that auto fills the state and zip according to the data in the lkuptblCity. All is working fine EXCEPT we have an Address 1 and Address 2 field for the employees.
I have two separate fields in the Staff table to store the data, as needed for reports. I have two separate fields on the form but they will not work due to pulling from the same table.
I need to get x and y coordinates for each device, but the data has to get looked up from 2 other tables.
I have a table (called InstReclosers) that has device names. Each device is on a Section. I can go to another table (called InstSections) and look up what Node that particular section is tied to. Then I need to go to another table (called Nodes) to get the X and Y location for that particular node.
How I can go about getting this X and Y data into the InstReclosers table?
...in summary, InstReclosers has device name and section name. InstSections has section name and node name. Nodes has node name and XY coords. Need XY coords for each device in InstReclosers.
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 am looking to add 3 or more different list values into the same column on the same table.All lists are stored in seperate tables within the same database.
My colleague has a multiple table database and uses lookups for some fields. The simple query was to extract 3 fields and display all records from those fields. The result of the query was that the selected fields were listed first followed by all other fields which are usually not displayed.
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'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'.
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.
