Loop update table (1 Viewer)

[Luka]

Hi everyone

I have a form and a subform both linked to the table. Subform has increment line number.

1 - first record
2 - second record
3 third record,...

The question is how to reset increment line numbers in subform if i delete second record?

Soo the result would be:

1 - first record
2 - third record

All values are stored in table so I was thinking about updating and then requery the subform.

I could realy use some help. Thanks

Here is a link to another forum with the same question:

Thanks for reply, but link wasn't much of a help.

I forgot to say that i don't use Autonumber field but a text field for increasing number. And i calculate sequential number in VBA and put it into table and then requery the subform.

I want to know how to make loop (or any other code) to update the field in table where that sequential number is stored?

I searched forum but nothing seems to work.

This is the code that i use and doesn't work:

Dim Counter As Integer
Dim CountLines As Integer
Dim rst As DAO.Recordset

Counter = 1

CountLines = DCount("MyFieldId", "MyTable", "MyFieldId= Forms!MyForm!MyFieldId")

Set rst = CurrentDb.OpenRecordset("MyTable")
With rst

Do Until Counter = CountLines

rst.Edit
!SequentialNumberField = Counter
rst.Update

.MoveNext
Counter = Counter + 1

Loop
.Close
End With


Thanks for help.

It would help to know what doesn't work. Offhand, I'd assume you'd want to open the recordset on the same restricted dataset as used in the DCount, not the whole table.

Yes i have a problem with recordset. I can open (recordset) a table or a query or a SQL string but without WHERE clause.

If i put where clause in recordset then i get error message Too few parameters. Excpeted 1.

I guess its something wrong with sql then?

Thanks, pbaldy i found your answer on a similar problem in some other thread.

In WHERE clause i should include brackets '" & Me!ControlName & "'.

Now the code works excellent.

Thanks again.
