I have a form with search fields and then the search results are shown in a subform below the search fields.
By default the subform loads all records prior to any search criteria being entered.
As this database grows the number of possible records to search will get quite large, so I don't really want the subform to load all records before the user attempts to makes a search.
What's the most performance-friendly way of loading the search results subform without showing any of the records to begin with?
I've considered setting the subform recordsource SQL to search for something I know will never be in the results... but I'm thinking that still requires the records to be loaded first and then filtered (might be wrong about this though).
Ideally I'd like the search results subform to load with the field names of the recordset only, but with no records until the user attempts a search.
Set the subform's record source to a query which returns a single manufactured row.
SELECT
0 AS id,
'' AS fname,
'' AS lname,
'' AS email
That will not pull any records from your table.
After you gather the user's search criteria, build the new SELECT and assign it as the record source.

I am creating a data entry form for employee information in Access 2016, which contains a fairly standard subform for work history.
In this subform, I have a SQL query to limit the items being pulled. The query itself works fine and is returning the correct results.
It essentially chekcs if the job position is open, (i.e. does not exist in history without an end date), or if it is the same as the current record.
The problem I am having is that I cannot seem to make the desired text display consistently.
The combobox itself is pulling 3 fields; job_id (index), job_title, and shift (job_title and shift are a unique combination, with job_id just being an autogenerated number).
The actual value being stored is the job_id, but I would like for the combobox to display the job_title after being selected.
This displays correctly when it is first selected, but if I then select a new job_id on a different record (where an event to requery occurs), any item without an end date stops displaying.
I have an event to requery this combobox on getfocus. I am almost positive that the problem has to do with anything missing an end date re-querying, and then not finding itself in the list, and then displaying a blank.(The data itself is not being deleted, just the display)
If I allow the index-column to be displayed, it no longer shows up as a blank, but it only displays the ID number which is not inherently useful to the end user.
If there is anything I can do to clarify please let me know.
I have a table [inventory] with inventory items, and a bunch of columns with different information for those. Mainly, part#, description, price. I am trying to create both a purchase order form [POForm] and, and a inventory transactions form [TransactionsForm], but that one thing I've been stuck on is getting a combo box look up I use to select the part# from [inventory], to also fill my fields for description, and price for that item in my form. I need the fields that are filled to be able to have formula's run off of them, and the information to be saved into the table for that form [TransactionsTable], [POTable].
I've tried making my part# combo box include the fields for the description and price, and using =[part#].[column](x) in the other fields as a lookup, and it looks right visually, but that is apparently just a visual of that data, but technically the field is still blank, because those other fields remain empty in the table for that form, and I am not able to run a formula off the price.
As per my understanding and please correct me if I am wrong. you have a form that shows your inventory data Part# Description & price. This form has a combo box that allows you to select a particular part # to view its related record data description and price.
Now you want to click a command button after selecting a particular part # to update your transaction form and POtable.
1.you have to create a query,
2.insert the inventory table in it
3.select append from the query type in the ms access ribbon
4.a window will appear, choose the transaction table as the destination table to append to.
5.double click on the fields that you want to retrieve its data from the inventory table
6.then in the table below in the query itself in the "append to" row you will find drop-down menu including all the fields from the transaction table. choose the corresponding fields. note if the fields have the same name in both tables access will do it automatically.
7.in the criteria row type the following [Forms]![Inventory Form Name]![the name of the field in the form]. do that for each field in the happen query.
8.save the query and name it
9.go-to design view in your inventory form and create a command button, in the click on event creat macro of the following: openquery-->type the append query name
10.save and close macro builder
11.open your form, select part#, click on the button
12.access will ask you to confirm appending process. click ok/yes
13.check your transaction table to confirm that the append process was successfully performed
14.Tip if you do not want the confirmation msg of append to appear, in the click on event go to the macro builder and choose in the ribbon show all actions then in the first line of the macro builder insert setwarnings - NO
the same is to be applied for the POtable.
Anyways, I hope you find this clear and helpful but I have only one concern you do not have to append part description and price in transaction and PO tables as you already have this data in your database in the inventory table. Generally speaking no need to include the same information in multiple tables otherwise you are not benefitting from the idea of a relational database.
I hope I addressed your inquiry.
I have created a form whose comboboxes get "DISTINCT"-populated with values (from a table), which means nothing is selected at first, but the combobox offers a load of values to select from named table. In Field 1 I select a value and then Field 2 automatically loads in only values from the table where the criteria fits the value from the first field and so on. This way, I am narrowing down the numbers of applying recordsets from my table down to 1 or 2 just by clicking and choosing options. My Form looks this way.
I have a total of 16 rows where in each row I can narrow down parameters to 1 specific item from the table.
With pressing a button, I can write these values into another table where they will get a save ID and a save name. This all works flawlessly.
I also added a loading button, where I can select the savenames from the savetable and the form will automatically get filled with the values from the savetable. But as soon as I do this, no values are suggested anymore in the field that contains multiple Columns. I tried a Requery, I tried reassigning the Rowsource, I tried just deleting the values in the fields before, nothing helps. I have to use my "erase" function where I set all fields to "Null" to be able to get the "suggesting values" back to work.This is how it looks after loading
In the regarding field should be at least 3 values which get not displayed anymore.
It feels like filling the forms' fields with comboboxname.value = rs!valuefromsavetable deletes or blocks the rowsources from working.
Can someone help me here?
I have a MS 2010 Access Report that needs to be populated by records that a user pre-chooses. For example.
Form1 has 2 fields, LOT# (which is record id) and CheckoffBox (unbound).
User checks which Lot#'s (records) he wants displayed, then clicks REPORT button. Report only shows selected records.
Can someone help me create the code?
In order to allow the user to use a check box to select multiple records, the list presented in form 1 must be based on a table that has LOT# and a yes/no field. (ie form 1 must be based on a query or a table that ahs this yes/no field).
If only one user will ever use this at any one time then you can simply add a yes/No field to the table that has all the LOT# values.
On your report you then only print those lot numbers that are checked.
Your report simply has to have SQL with a where clause that only print records that have the Yes/No field ticked. (=true =-1).
If many users are going to use this form at the same time it gets more complicated as obviously they all need to have their own "set of yes/no fields".
So you would need to copy the table with the LOT# into a temp table for use by each user (it might have a primary key of USERID, LOT#, or it might be a table with just LOT# and yes/no fields, that only a user can access - ie in their own copy of the database file that has the front end forms).
Anyway, assuming it's a single user, creating the above should be quite straight forwards.
On opening form 1, you might use the form_open event to run a SQL statement that sets all the Yes/No values to No. Although you might not want to do this.
Use
docmd.SetWarnings false
Docmd.runsql "UPDATE theTable SET YesnoField = 0 WHERE YesnoField = -1;"
docmd.SetWarnings true
Let me know if you can take it from here.
Here is my problem and I do not know where and how to start to search about this.
In a MS Access database users will have a list of records returned from a query. Let's say employees which are active (employed). This table has a related table let's say departments (related through departmentID in both table).
What I want to do is to make form (or something else which would do the same job), where user will select some records (probably with checkboxes associated with each record) and there will be a single combobox with department names. When user selects a department name, its departmentID should be saved into departmentID field of these records.
I have created a form with a query of active employees (form with multiple items). And put an extra field in Detail section with a checkbox. In Form footer I have a combobox with Department names and IDs (not shown to user), and a button to save values.
I have to now figure out, how to select all rows/records with a checked checkbox and update them. I am by the way familiar with VB and SQL.
I would appreciate any idea/knowledge on how to solve this.
An extra field in the Detail section won't help you if you don't link it with a data field in the displayed table. If you can do that, then you have simply to make a VBA function to update all selected rows, and refresh the recordset.
If you cannot modify your table, you'll have to create a new table with just the key columns of your master table, and manage it via VBA. Better to use the first option if you can, it pollutes your schema, but in most cases that won't be a problem for an Access database.
