    Find AutoIncrement & Primary Key fields in ADODB Recordset

    Hello again, everyone. I've run into yet another issue I can't seem to overcome with any of the resources at my disposal. Is it possible to determine if a field in an MS Access (2003) table is AutoIncrement and/or a Primary Key by looking at an ADODB Recordset from that table?

    I'm trying to convert data from an Access database over into MySQL. As I go through each of the tables in my Access database, if that table doesn't already exist in the MySQL database, I need to create it. I'm building a SQL command string by looping through the field names of an ADODB recordset from the Access database. During this loop, I would like to identify those fields that are setup as AutoIncrement/Primary Key fields so that I can include those in my SQL statement appropriately.

    Code:
        Private Sub CreateNewDestinationTable(ByRef TableName As String)
            Dim X As Integer
    
            DDBCommand = "CREATE TABLE [" & TableName & "] ("
    
            For X = 0 To OTempRS.Fields.Count - 1
                DDBCommand = DDBCommand & "[" & OTempRS.Fields(X).Name & "] "
    
                         DDBCommand = DDBCommand & "VARCHAR(" & OTempRS.Fields(X).FieldSize & ")"
    
                ' --- Here is where I would add the conditional statement to include
                ' --- the appropriate SQL commands to create the field as a Primary
                ' --- Key and/or AutoIncrement field as needed.
    
                If X < OTempRS.Fields.Count - 1 Then
                    DDBCommand = DDBCommand & ", "
                End If
            Next X
            
            DDBCommand = DDBCommand & ")"
        End Sub
    I'm sure I could probably pop up a dialog to request user intervention to identify these types of fields, but it would be nice if I didn't have to. Any ideas or suggestions would be greatly appreciated. Thanks for your time.
