SQL Query Generates no Data

The code below does not work when I attempt to use a wildcard in the WHERE clause.
The code below does work if I remove the wild card (asterisk).

The code below generates this SQL statement when I include the wildcard.
SELECT * FROM view_eCAP_DATA_EXCEL WHERE WBS LIKE '433*'
and generates this SQL statement when I remove the wild card.
SELECT * FROM view_eCAP_DATA_EXCEL WHERE WBS LIKE '433CA'

Private Sub UpdateQueryTable_BySubsystem(myPath, myFile, myViewName, myDefaultDir, myDestination, myDataSheet, myFieldToFilter)

For an ADO recordset, use % for the wildcard with LIKE instead of *:

 mySQL = "SELECT * " & _
              "FROM " & myViewName & " " & _
              "WHERE " & myFieldToFilter & " LIKE '" & mySubSystem & "%' "
