    <p>Seems a common enough problem this, but most solutions refer to concatenating multiple SQL commands, something which I believe can't be done with ADO/VBA (I'll be glad to be shown wrong in this regard however).</p> <p>I currently insert my new record then run a select query using (I hope) enough fields to guarantee that only the newly inserted record can be returned. My databases are rarely accessed by more than one person at a time (negligible risk of another insert happening between queries) and due to the structure of the tables, identifying the new record is normally pretty easy.</p> <p>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.</p> <p>What's the best way to insert a record into an Access table then query the new primary key from Excel in this situation?</p> <p>Thanks for the replies. I have tried to get <code>@@IDENTITY</code> working, but this always returns 0 using the code below.</p> <pre><code>Private Sub getIdentityTest() Dim myRecordset As New ADODB.Recordset Dim SQL As String, SQL2 As String SQL = "INSERT INTO tblTasks (discipline,task,owner,unit,minutes) VALUES (""testDisc3-3"",""testTask"",""testOwner"",""testUnit"",1);" SQL2 = "SELECT @@identity AS NewID FROM tblTasks;" If databaseConnection Is Nothing Then createDBConnection End If With databaseConnection .Open dbConnectionString .Execute (SQL) .Close End With myRecordset.Open SQL2, dbConnectionString, adOpenStatic, adLockReadOnly Debug.Print myRecordset.Fields("NewID") myRecordset.Close Set myRecordset = Nothing End Sub </code></pre> <p>Anything stand out being responsible?</p> <p>However, given the caveats helpfully supplied by Renaud (below) there seems nearly as much risk with using <code>@@IDENTITY</code> as with any other method, so I've resorted to using <code>SELECT MAX</code> for now. For future reference though I would be interested to see what is wrong with my attempt above.</p>

    1. COUsing `Max` can be tricky… if someone else is inserting records, it may give you another record’s ID. If you are the only one inserting records, go ahead.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
