More than 1000 parameters in an SQL IN (VBA)

I'm making an oracle query from vba and ran into the limitation that there can't be more than 1000 entries in a SQL IN statement.

   LRow_Last_Product = Workbooks("test.xlsm").Worksheets("Check").Range("A" & Rows.Count).End(xlUp).Row    For Each RngZelle In Workbooks("test.xlsm").Worksheets("Check").Range("A7:A" & LRow_Last_Product)        If StrISINs = "" Then            StrISINs = "'" & RngZelle.Value & "'"        Else            StrISINs = StrISINs & ", '" & RngZelle.Value & "'"        End If    Next RngZelle'WHEREStrSQL = StrSQL & "t.externref IN (" & StrISINs & ")"

I was thinking about creating a function that would generate a second IN with an OR if there are more than 1000 parameters. What is the most efficient way to solve this?

Thanks
