Move a record from one table to another upon an event

[Hashirama]

I don't know where to put this. Moderators please move this to the appropriate section if required
I have 2 tables, a and b.
Then I have records in each table with fields ,Name and Status(Done and Done_s)
I want records having "Done_s" to be moved to b whenever the change has occurred. Is this possible?(I have tried somethings with Macros but didn't work)

I am completely new to access. So any help will be appreciated

Hi, I don't use Macros so no help there. But if you want to copy a record from one table to another, why is my question? Duplicating data is a bad idea! Why not instead use a query for your form based on both tables?

No. I don't want to copy data. I want to Move it to b.

Hi -

A "move" actually be thought of as two operations: first, a copy from a to b, and then a Delete from a.

When do you want the move to occur - as soon as a user makes the change from "done" to "Done_S"? Not really a good idea, IMO, because what happens if a user makes a mistake - how do you get the record back?

Assuming are using a form and editing TableA, what you want to do could be done with three lines of code in the On_click event of a command button on the form:

currentdb.execute "Insert into TableB select * from TableA where Status = 'Done_s' ", dbfailonerror
currentdb.execute "Delete from TableA where Status = 'Done_s' ", dbFailonerror
me.requery

line 1 copies the records from Table A to table B
line 2 deletes them from Table A once they have been copied
line 3 updates the records you see on the form to remove the moved ones

Thanks. I am actually using just a plain table. Do you think a form is a better way?

[Hashirama]

This is what I am trying to do (Done_no is just another option)
It's just facebook page shares, I want to keep track of them all.


A form shows one record only . So I can't use it

[burrina]

You should NOT be working in your tables directly! YES, a form. Tables are for storing data, forms are for entering data. John_G gave you some good advice.

[John_G]

If you are just entering or updating the data directly in the table, there is not a "better" way - there is "no" way. Tables do not have events, and cannot react in that manner to changes. That's what forms are for.

"A form shows one record only . So I can't use it"

Not true - it depends on the "Default View" setting in form design. The "Single Form" shows only one record at a time, yes, but "Continuous Forms" and "Datasheet" views allow multiple records to show at the same time, and you can scroll through them.

Oh, thanks guys. Thank you very much.
But there is no button in the form. It is a drop down list. So what about using "After update" event?

[John_G]

The After Update of a dropdown list would probably work too - what is in the dropdown list, and what (if any) table field is it bound to?

It's {Done,Done_no,Done_s,No,No_s}

{Done_s,No_s} will always go to "In debt" table(My image above)
{Done,Done_no} will go to "Done" table.
{No} will go to "No answer" table

[Hashirama]

Anyone?

Hi -

Yes, the after update will work. The only change needed is that the table a record is moved to will vary according to the value selected, and the criteria to identify the record will change. But, as I said earlier, you'd have to be careful not to make a mistake, because as soon as you change the status, the record is gone from the table you are looking at.

"Done" and "Done_no" won't have to be moved as they are already in the proper table.

Your code could be something like this:

Select Case Status
  Case "Done_s", "No_s"
     currentdb.execute "Insert into [In Debt] select * from [Done] where ID = " & me!ID, dbfailonerror
     currentdb.execute "Delete from [Done] where ID = " & me!ID, dbFailonerror
     me.requery
  Case "No"
     currentdb.execute "Insert into [No Answer] select * from [Done] where ID = " & me!ID, dbfailonerror
     currentdb.execute "Delete from [Done] where ID = " & me!ID, dbFailonerror
     me.requery
  case "Else"
    '
    '  No action required
    '
End Select

One possible pitfall here - if ID is an Autonumber field, there is no guarantee that it will be the same is the tables you are moving the records to ([No Answer] or [In Debt])

Is there no way to make an ID which is unique to all the tables?
