How to Get Id of Newly Inserted Record Using Excel Vba

How to get id of newly inserted record using Excel VBA?

About your question:

I'm now trying to update a table that
does not have much scope for
uniqueness, other than in the
artificial primary key. This means
there is a risk that the new record
may not be unique, and I'm loathe to
add a field just to force uniqueness.

If you are using an AutoIncrement for your primary key, then you have uniqueness and you could use SELECT @@Identity; to get the value of the last autogenerated ID (see caveats below).

If you are not using autoincrement, and you are inserting the records from Access but you want to retrieve the last one from Excel:

• make sure your primary key is sortable, so you can get the last one using a query like either of these:

  SELECT MAX(MyPrimaryField) FROM MyTable;
  SELECT TOP 1 MyPrimaryField FROM MyTable ORDER BY MyPrimaryField DESC;
  

• or, if sorting your primary field wouldn't give you the last one, you would need to add a DateTime field (say InsertedDate) and save the current date and time every time you create a new record in that table so you could get the last one like this:

  SELECT TOP 1 MyPrimaryField FROM MyTable ORDER BY InsertedDate DESC;
  

In either of these cases, I think you would find adding an AutoIncrement primary key as being a lot easier to deal with:

• It's not going to cost you much

• It's going to guarantee you uniqueness of your records without having to think about it

• It's going to make it easier for you to pick the most recent record, either using @@Identity or through sorting by the primary key or getting the Max().

From Excel

To get the data into Excel, you have a couple of choices:

• create a data link using a query, so you can use the result directly in a Cell or a range.

• query from VBA:

  Sub GetLastPrimaryKey(PrimaryField as string, Table as string) as variant
      Dim con As String
      Dim rs As ADODB.Recordset
      Dim sql As String
      con = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
            "Data Source= ; C:\myDatabase.accdb"
      sql = "SELECT MAX([" & PrimaryField & "]) FROM [" & MyTable & "];"
      Set rs = New ADODB.Recordset
      rs.Open sql, con, adOpenStatic, adLockReadOnly
      GetLastPrimaryKey = rs.Fields(0).Value
      rs.Close
      Set rs = Nothing
  End Sub
  

Note about @@Identity

You have to be careful of the caveats when using @@Identity in standard Access databases(*):

• It only works with AutoIncrement Identity fields.

• It's only available if you use ADO and run SELECT @@IDENTITY;

• It returns the latest used counter, but that's for all tables. You can't use it to return the counter for a specific table in MS Access (as far as I know, if you specify a table using FROM mytable, it just gets ignored).
  
  In short, the value returned may not be at all the one you expect.

• You must query it straight after an INSERT to minimize the risk of getting a wrong answer.
  
  That means that if you are inserting your data at one time and need to get the last ID at another time (or another place), it won't work.

• Last but not least, the variable is set only when records are inserted through programming code.
  
  This means that is the record was added through the user interface, @@IDENTITY will not be set.

(*): just to be clear, @@IDENTITY behaves differently, and in a more predictive way, if you use ANSI-92 SQL mode for your database.

The issue though is that ANSI 92 has a slightly different syntax than
the ANSI 89 flavour supported by Access and is meant to increase compatibility with SQL Server when Access is used as a front end.

Autonumber value of last inserted row - MS Access / VBA

If DAO use

RS.Move 0, RS.LastModified
lngID = RS!AutoNumberFieldName

If ADO use

cn.Execute "INSERT INTO TheTable.....", , adCmdText + adExecuteNoRecords
Set rs = cn.Execute("SELECT @@Identity", , adCmdText)
Debug.Print rs.Fields(0).Value

cn being a valid ADO connection, @@Identity will return the last
Identity (Autonumber) inserted on this connection.

Note that @@Identity might be troublesome because the last generated value may not be the one you are interested in. For the Access database engine, consider a VIEW that joins two tables, both of which have the IDENTITY property, and you INSERT INTO the VIEW. For SQL Server, consider if there are triggers that in turn insert records into another table that also has the IDENTITY property.

BTW DMax would not work as if someone else inserts a record just after you've inserted one but before your Dmax function finishes excecuting, then you would get their record.

How to know the ID of the most recently added record?

Firstly, you should be aware that this method of obtaining the autonumber value for the most recently added record only works reliably when evaluated within the scope of the same database workspace which created the record (when using DAO) or the same database connection (when using ADO). Evaluated independently of such connection, the statement will merely yield 0.

Example

Say we have a table called Table1 with two fields:

Table1
+------------+--------+
|     ID     | Field1 |
+------------+--------+
| AutoNumber | Text   |
+------------+--------+

We can create a new record using the following code:

With CurrentDb
    .Execute "insert into table1 (field1) values ('abc')"
End With

If we want to find the value assigned to the AutoNumber field ID, we can then do this:

With CurrentDb
    .Execute "insert into table1 (field1) values ('abc')"
    Debug.Print .OpenRecordset("select @@identity")(0)
End With

What is @@IDENTITY?

Note that the SQL statement used in the above example is independent of any one particular table or field (there is no from clause), as the @@identity column merely refers to the last autonumber value issued (to any record within any table) for the current database workspace (DAO)/connection (ADO).

This T-SQL documentation may help with your understanding, but note that this applies to SQL Server, not MS Access, and so whilst this provides a description of the purpose of @@identity, not everything will translate directly to MS Access.

How Does .OpenRecordset("...")(0) Work?

As for the use of (0) directly following the .OpenRecordset method, this simply shorthand for accessing the first item in the Fields collection (which is the default member of the Recordset class), and is therefore equivalent to:

.OpenRecordset("select @@identity").Fields(0)

How to get the last record id of a form?

There is a function DMax that will grab the highest number.

Dim lastID As Integer
lastID = DMax("IDField","YourTable")
' or = DMax("IDField","YourTable","WhenField=Value")
MsgBox lastID

The other Domain functions are:

• DAvg
• DCount
• DFirst
• DLast
• DLookup
• DMin
• DStDev
• DStDevP
• DSum
• DVar
• DVarP

Retrieving last inserted ID from MS Access database

Assuming you have an auto increment column in the Tournaments table, you can do a "SELECT @@IDENTITY" to get the id of the last inserted record.

BTW, is the SanctioningIDTxt.Text unique? If so, can't you use that?

Getting the newly added AutoID of MySQL using VBA in MS Access

So my answer comes from both ComputerVersteher and User2834566 info.

I had to run two queries, both as passthrough and running on the same db instance to make sure it returned the right value:

Dim strSQL As String
Dim qdf As DAO.QueryDef
Dim db As DAO.Database
Dim rst As DAO.Recordset

strSQL = "INSERT INTO medstome_masterdb.tblChemists (chemName) VALUES ('newchem')"
strGETID = "SELECT @@IDENTITY"

Set db = CurrentDb

    With db
        Set qdf = db.CreateQueryDef("")
            With qdf
                .ReturnsRecords = False
                .Connect = oCon
                .SQL = strSQL
                .Execute
            End With

            With qdf
                .ReturnsRecords = True
                .Connect = oCon
                .SQL = strGETID
                Set rst = .OpenRecordset(dbOpenSnapshot)
                gPxID = rst(0)
                Debug.Print gPxID
            End With
    End With

This works perfectly!

Create unique id for each SQL record in VBA

You could move your RecordID logic inside the loop like this:

For Each row In rng.Rows
   arr(0, 0) = arr(0, 0) + 1
   query2 = "INSERT INTO tbl_eInvoice_Main (RecordID) values (" & arr(0, 0) & ")"
   con.Execute query2
Next row

However, this approach won't work well if you have multiple users. Just something to keep in mind.
