Hi,
I use access database for a website. I would like to run a trigger in a specific table when updating a record.
Is it possible to create table level triggers in Access at all, if it is, pls. give me short direction. (as far as I know there are lot of events, but this events occur only in native access application only, and can not be handled outside of access, am I right?)
thanks a lot

Thanks to S.baxter I have used some code to loop through a recordset and select each record in turn in a form that uses the recordset as the Rowsource of a combo box. However, there is an After_Update event attached to the combo box which is not being triggered.
MS Help says :- "If you move to another record or save the record, the form's BeforeUpdate and AfterUpdate events do occur." I have tried this but can't get it to work. Would it work if I could move the focus to another control on the form and if so how do I do that?
Thanks

I am updating a value in an unbound control on an unbound form. When the value in the control is changed I want a sequence of code to execute. Specifically changing the record source of a subform and refreshing it.
The problem I have is that when the value of the unbound text box is control is changed (I am using a button to change the value as a test) the after update event on the text box does not do anything.
I did a simple test using a button to change the value in the text box and in the afterupdate event of the text box asked it to output the value of the textbox to a message box as shown below.
The problem is this does not work, nothing happens. If I tab out of the text box or change the value with the keyboard however the msgbox appears. Just not via a vba change.
Code:
Private Sub Prod_ID_AfterUpdate()
Dim pid As String
pid = Me.Prod_ID
MsgBox pid
End Sub
Private Sub Button_Test_Click()
Me.Prod_ID.SetFocus
Me.Prod_ID = "TEST"
End Sub
There are around 100 customers.And on application open, need to check if customer has paid invoice. If the customer has paid/not paid need to change the status accordingly. Form on open event changes status of only the first customer.Form on current changes status only if we move to the specific record. Is there an event to trigger to check the entire table records on application open?
View 9 Replies View RelatedI have a main Part form and a Spec subform linked via Part key.
I need to add 6 Spec records automatically when a new Part is added so user can select desired Specs (default value is "n/a" for al 6 entries).
Right now I have the Spec entries added in AfterInsert for Part form, but I have to navigate out and back into record to trigger Part insert. I cannot add the Spec entries until the Part entry is added.
Is a command button my only option? Or is there another way?
AfterInsert is too late, and BeforeInsert is too early; that gets triggered as soon as the first character is typed in Part name.
Basically, I have progress table with learners and each learner must undertake 4 tests. Once they have completed each test, in the original learner table, I want it to show that they have completed the task if all 4 boxes are checked by it triggering one final check box.

View 14 Replies View RelatedI've got a subform that im writing code for, once a user enters a value in one of the fields i want to make sure they cant change that field (and two other fields in that same record, though the rest of the fields are fine to edit at will)
I've got a function already written to validate the data in the record and decide whether or not the fields are enabled and disabled, however im having trouble finding an event in which to activate the function
Is there an event that triggers whenever a user selects a different record?
Any chart or list with all the handlers and how they trigger (in relation to each other) and when?
How to structure some MS Access 2007 Forms for the following scenario.
My table structure is as follows:
Product
++++++
ID (pk)
ProductName
...
Tag
++++
ID (pk)
TagName
ProductTag
+++++++++
ProductID (fk)
TagID (fk)
I want to have a main form that allows me to search for and displays a list of all products (and the dozen or so attributes for each product) that meet that criteria (I'm thinking a continuous form view of products).
So far so good. No problems.
Now I want a "tagging" form to the right of my continuous forms product list that is linked to the product which currently has focus. The tag panel should always show a complete list of all Tags. I want a checkbox next to each tag that I can switch on and off whether that tag applies to the currently selected Product. I also want to be able to add tags on the fly (without leaving the main form).
I think I have three forms in play :
Main Form
Product Form (subform to Main) my product search criteria is probably on this form header.
Tag Form (also subform to Main)
But with this approach I'm have trouble linking the two sub forms to each other. Actually, I'm having huge trouble figuring out how to display the list of all tags with a check box that when checked on and off creates / deletes a record in the ProductTag table and I really want Access to do as much of the CRUD as possible. I would prefer to avoid writing screeds of SQL INSERTS/DELETES on events. Am I asking too much of Access?
Hi
im going to make an update query to deduct the quantity purchased of a product from the stock amounts but i need it to run the query automatically everytime a new record is added to the table
any ideas how to do it?
I have an after update event that populates, Date, Time and User into corresponding fields when the record status changes to closed.
However... Whilst the information is recorded on the form it does not record to the underlying table is there any reason for this, or anything that I am not doing correctly?
I have a table with many records, using a form with an update button click event, I would like to update ALL records where the Item in the table = the Item in the form.
There are 6 checkboxes and 6 text boxes that will need to be updated, but right now I am just trying to test if i can even change one text box to keep it simple. I have tried to start by using this:
Code:
Dim mySQL As String
Dim ItemNo As String
Dim SO As String
mySQL = "UPDATE BT200 SET Part = '" & SO & "' WHERE Item = " & ItemNo
DoCmd.RunSQL mySQL
So every time i run this command button, it gives me a prompt "You are about to update 0 row(s)". Nothing gets updated at all, I am clearly missing something vital here.
I'm not sure if this is the proper forum for this post. I have a database in access in which i need to mimick a trigger like behavior. As far as I know access does not support triggers. When a user updates a record I need a LastModified date field to be updated with the current date automatically.
I've seen several examples of how to accomplish this using forms, however, the users of this database do not use forms. They are editing the records by hand by opening up the table and simply typing.
Any help you can provide is greatly appreciated.
Thanks!
I am creating a student database in Access. I have connected a number of tables through primary keys with RI.
When I create a new record in the student table, I need to insert the student id manually in the grade table.
In SQL Server, I would use an insert trigger to do this automatically. How about in Access?
I need to get this new student id in a number of similar tables: scores, assessments, terms.
I have been populating the student table with data, exporting to access, importing as a new table, adding the id field, creating the relationship, then populating the table with the missing data, which is very labor intensive.
I have a lot more data to enter.
An easier way to do this in Access would be greatly appreciated.
Thanks,
Joe
Does anyone know of a way to trigger a function in Access when a specific email is received in Outlook?
Thank you for reading this question and for those that reply, thank you for your time and knowledge.
I am new to MS access. I have to delete records from the 2 tables, when the parent record gets deleted. I have a delete button in my form wherein the user deletes the particular record from the parent table.
When the delete button is pressed, the parent record gets deleted from the table. But I need to write a after delete trigger on the parent table to be able to delete the relevant records from the other two child tables, based on the current parent id.
what code should I write ? and should I locate the records in the before delete trigger and then write the code to delete the child record in after delete trigger ?
Hi,
In Form of the MS Access.
How can I make the form cannot close if the field is Null when I click the close button?
frm1:
Field Name: Date, Id, Name
The 3 field names are required to input.
Before Update Event:
if (isnull(date)) then
date.setforce
end if
if (isnull(id)) then
id.setforce
end if
if (isnull(name)) then
name.setforce
end if
It works well when I go to next record (suppose I miss one field)
However, It doesn't work when I click the close button, the form is closed.
I want the form cannot close until fill out all fields. It cannot go to the missing fields.
I have a question, when I click close button, Must the form be closed even though I set up the field to be "setforce"?
Thanks.
I have a Product(Table) and a Quotation(Table) linked with one to many Relation.A Query based on these Tables
and a Quotation(Form) which I use a ComboBox(ARTNO) which i have an event at AfterUpdate.The aim is to

Here is the AfterUptade Code:
Private Sub ARTNO_AfterUpdate()
On Error GoTo Err_ARTNO_AfterUpdate
Dim strFilter As String
' Evaluate filter before it's passed to DLookup function.
strFilter = "ARTNO = " & Me!ARTNO
' Look up product's PRICE and assign it to PRICE control.
Me!PRICE = DLookup("PRICE", "PRODUCTS", strFilter)
Exit_ARTNO_AfterUpdate:
Exit Sub
Err_ARTNO_AfterUpdate:
MsgBox Err.Description
Resume Exit_ARTNO_AfterUpdate
End Sub
The problem is that in the Box(PRICE) i have always the same price, in any product selection.
Does anybody knows why?Please help
Hello All,
I have a question.
Can I have in Access 2000, in the After update event a code like this:
DoCmd.RunSQL ("Update Table1" & _
"SET [Table1].Field1 = (SELECT DISTINCT [Table2].[Field1] FROM [Table2] " & _
"WHERE [Table2].[Field22]= "& Me.textbox & " And (Left(Field1,5)= "00000" ")")
?
I have 2 tables. Based on what the user enter in "Textbox" I want to query Table 2 (with conditions) and to update Table 1 with the value I found in the Select statement. (Table 1.field1 = table 2.field1)
Thank you.
How to update data from one table to another table using form.
I have data coming from design team in Database 1 and using form i want search data and assign the job to a person and store it in the database with his name. I have to do this because database from design team is read only.
I have a table that is a list of all of my events. Each record of events should have a child table that list all of the things that happened at the event. When a new record (event) is added how can I have a new child table created and linked to that record. Also I have a blank table to serve as a template for what each child should look like. How do I make sure this occurs? The child tables can have the same name as the index. I am just using numbers 1- for the index with 1 being the first event and so on?

I need to trigger an event for when a text box is updated.
However, I cantuse on_update() because the text box is updated by dlookup (and on some of my other ones by vb code), and on_update() only works when the user physically enters a value.
Which event should I use. If there isnt one, is there a work around?
I need an event for when a text box is updated. Not by the user typing into it, but when VB code or something like Dsum() changes its value automatically.
What event can I use? Does one exist for this?
Hi
I have form with a series of text boxes in which users can edit the data that is populated in them. For one of the text boxes I want to add an after update event, so that if the user changes the value in the text box, a message window appears telling them to click on the submit button at the bottom of the form.
Does anyone know the code that I should use to make this message appear when the value in the text box is changed?
I have a main form with 2 subforms. I have a checkbox on subform1 "frmExpediteS" that when checked i would like the Value in Feild "PO" of this subform to appear in "PO" in a second subform2 "frmExpediteDetails". I think I need an after Update event but not sure of the code to use.
Can someone please steer me in the right direction.
