I have an Access database that is used to store basic info in a table such as first and last name. How would I go about adding the functionality to lookup by last name?
Is there a way to type in the last name and then hit like F12 or something like this? Can someone please point me in the right direction or provide me a link?
SELECT tblPatient.LName AS [Last], tblPatient.FName AS [First]
FROM tblPatient
WHERE (((tblPatient.LName)=[Enter Last Name]));
How do I tie this into my form now?
I'd suggest you create a form, with a textbox 'search' at the top, then either a listbox or subform below to display results.
The listbox record source would be:
SELECT tblPatient.LName, tblPatient.FName
FROM tblPatient
WHERE tblPatient.LName LIKE Forms!myForm!search & '*';
You can either add a Search button, which requeries the listbox, or do the requery via the Change event of the search textbox. The later may be slow if you have a large number of records; if that's the case, you could check that at least 3 (?) characters have been entered before calling the requery.
You just need to create a query in which you put =[?] as the "last name" value.
When you open that view, you'll be asked to type in a lookup value for that field.
Not sure if this is what you are trying to archieve, though...
This is probably a bit overkill for what you want to do, but I assume that you want to perform a search by last name. You should be able to glean the information you need from this article:
Build a search criteria form
http://www.everythingaccess.com/tutorials.asp?ID=Build-a-search-criteria-form
You can create queries in Access if the user you're targeting with the searchability has Access themselves.
From the main Access UI (assuming Access 2007), go to the Create tab and then select the "Query Wizard." Here is an article on the subject.
Otherwise you can create a program and connect to the MDB/ACCDB file running the query programmatically.
Seeing you wish to look up a name and populate the form based on the name selected, I suggest you need a combobox. There is even a wizard for doing exactly what you want. To start, you will need a form bound to a table or query, that is a form with a Record Source.
Add a combobox to your form
Select :
Find a record on my form based on the value I select in my combobox
Select the ID (primary key), Last and First name fields.
Access will display an example, suggesting that you hide the Key (id) column. Accept this.
Choose a name and finish.
There are a few other small things that could be done for neatness, but you will end up with a form that find the record you want. In addition, the combo will autocomplete if you type in a few letter.
If this is an mde, which your subsequent post seems to suggest it is, there is little you can do wuth out the original file. However, you could try opening the database while keeping the shift key held down and see if that allows you to edit. If you cannot get the original and the shift does not work, you could try rescuing the data, if it, too, is stored in this file.

I've run into a bit of a snag with a project I'm working on, and being new to Access I don't know if what I want to do is possible without VBA. I've looked around but all I can find are answers related to showing multiple columns, not controlling multiple fields in my DB.
To paint a picture I have a mapping system set up in my DB to help me distinguish the name and type of data is held in a table.
The setup is as follows:
-Data table is "LineItems" with an ID and the line data (think typical excel format)
-Mapping table is "LineItem_Mapper" with LineItem_ID, DataType, and Entity_ID
-A helper table "Data_Type" with ID and Name
-two "Entity" tables with differing properties both have ID and Name
The reason for the split is on data type is that the two types of data behave differently. One type has a parent child relation, and the other is a standalone row. I want to preserve this structure in my DB and feel I have done so with this mapping.
Now, on to the issue I'm running into. In my Access data entry form I want to use a combo box, as the options a user may chose for each line when entering are finite. However, this combo box is affecting the Mapping table above. I have been able to populate the box with my desired list with a custom query built from my 2 entity tables, but I don't know how to get Access to create or update the Mapping table using this box.
what I want to happen is when I chose something in the box, a line is created (or changed) in the mapping table with all 3 columns being populated. first the LineItem_ID for the line I am populating, and then the DataType and Entity ID to reflect the proper mapping.
Can Access do this on its own? Or do I need to do this with VBA?
As requested by the OP converting my commend as an answer (with a little bit more detail):
By far your best option is to use VBA. I doubt there is another way and even if there is it would be so convoluted it would be unworkable and unmanageable.
This should get you started:
In the combo box properties go tot the events tab and in After Update or On Change (look up the difference between the two events to see which behavior you prefer) click the down arrow and select [Event Procedure], then click on the … button. This will create a VBA module for you complete with the function that runs when the selected event is triggered.
You can use DoCmd.RunSQL "[Access SQL INSERT statement]" to add records to tables.
You can use Me.[MyComboBoxName] to get the current value of the combo box. Similarly the value of anything else in your active form.
You can use DLookup to get the value of any record in your tables.
Hopefully these will give you a relatively quick start.
I have a database built that, after all of the queries are done, it will spit out a form and I can filter through records and the relevant information will change as I filter through. To get there, I have to be able to reference a combo box located on my entry form (which contains all of the sales guys' ID numbers) in my queries. However, when I input the normal form reference in the criteria section '[Forms]![Entry Form]![ID]' and run the queries, it returns nothing. I figure that this is because in a lot of our live data tables, the ID numbers have spaces before or after them, which they have no spaces in the ID numbers listed in the combo box. I tried to use the trim function in my queries for the ID number field in the tables, but it still returned nothing.
Any advice on what else I can try? If more info is needed, ask away.
Change the Bound Column to 2, or whatever column it is in the row column, all under the property sheet data tab for combo box. It may be returning the ID rather than the text when selecting.
This is a case where the query designer isn't the best option. Instead, open it in SQL mode (there should be a dropdown in the upper left corner that allows you to change how you view the query) and change the WHERE clause to something like:
Trim(ID) = [Forms]![Entry Form]![ID]
It's not going to be very efficient, this is why you should never use bound forms because you can do the trimming on data entry and save on the overhead, but this should at least return data for you.
I figured it out!! The answer to my problem was I needed to manually type in the combo box options instead of importing the options from another table. For some reason that worked. Thanks for you guys' help again!
I am trying to write an Microsoft Access query from a form with a multi value field being the criteria. The field I am trying to use is called Population and the field is represented in my database as a List Box that allows multiple values and it is in the Building table. The values it allows are the following:
"Singles";"Familes";"Families with Children";"Youth/Young Adults";"Veterans";
The form that I am creating is called HousingSearch.
I am trying to create a form which uses this field, so someone could use the list box and check off the values they want and click on the button which would open a query. I know having done this with single value fields the criteria in the query looks something like
[forms]![HousingSearch]![Building]![Population]
but if you try the same thing for a multi value field nothing is returned for the query. Any help would be appreciated.
From the information you have provided it seems that the phrase [Forms]![HousingSearch]![Building]![Population] are combining a request that starts with a form and then jumps to a table.
You are asking access to find data in a form but the information you're most likely trying to access is in a table. I don't quite understand what you're end result is but I think that you most likely want to refer to your information this way [Building]![Population]. Referring to your data this way makes access look at the table of [Building] and then into the field of [Population].
It's been a while since you posted, if you haven't cleared things up already I hope this helps.
I have a form that is linked to a table in Access. I have an additional field which displays the sum of a few fields in the table. This field on the form is not connected to the table. I have the sum displayed on the form but what I noticed is that the sum does not appear until I move away and navigate to another record and come back to the original record. I don't see the addition as soon as I enter values in the respective fields.
Can someone help with this issue?
It sounds like you need to add some code to the After Update events of the controls for the fields used in the sum. That code can call the .Refresh method of the control that performs the calculation and update the total.
Edit
Another possibility is that there could be ambiguity between control values and field values if they have the same name. In Design View for a report if you drag a field from the "Field List" and drop it into a report then Access creates a report control with the same name as the field. This can confuse matters later because if any expressions refer to =[SomeColumn] it's not clear whether that refers to the field or the control. Often simply renaming the controls to something like txtSomeColumn can help if a report is acting strangely.
I am adding a part name to the database using a form, What code do I put behind the Add part button to validate against duplicate part names? (part number is the primary key) I think I need another recordset to search and compare the table but i'm a bit lost, any help would be great.
Private Sub btn_add_Click()
rs_parts.AddNew
With rs_parts
!partrno = lbl_partno.Caption
!Name = txt_name
rs_parts.update
end with
I've discussed my approach to this before, and given an example form for adding a new record.
I use an unbound form to collect the information needed to create the new record, and have it check for duplicates, and present a list of them to the user so the user can decide what to do.
In this case, it sounds like a unique index is in order, so you won't really need to worry about close matches. I would probably still use an unbound form to capture the new value and run the check before even attempting to add it. In that case, I'd just notify the user that it's a dupe.
Should you add a unique index to the part name field?
If you want, you can create a query on your part table with one column for the name and a parameter for the criteria they've entered in txt_name. Then pass the value they entered as a parameter to the query and see if you get any results.
