I am fairly new to vb.net and seem to be having some probelms doing an SQL statement. I am selecting data from more than one table from my Access database. A surname held on a database is typed and it is supposed to display results, related on the MemberID.
I get the error 'No value given for required parameters' at [da.Fill(ds, "RoyalYachtingAssociation2")]. The code I have is shown below. I do not think the SQL statement is finding a value. Any help would be much apperciated.

Public Class SearchInBDAOTRpt
Dim con As New OleDb.OleDbConnection
Dim userInput As String
Dim ds As New DataSet
Dim da As OleDb.OleDbDataAdapter
Dim commandString As String = "SELECT Owner.MemberID, Owner.FirstName, Owner.Surname, Owner.Address, Owner.PostCode, Owner.RYAMembershipNumber, Owner.PositionInClub, BoatDefectLog.BoatDefectLogID, BoatDefectLog.HullNumber, BoatDefectLog.Defect, BoatDefectLog.DateReported, BoatDefectLog.Repaired, BoatDefectLog.DateRepaired FROM Owner, BoatDefectLog " & _
"INNER JOIN ([Owner] INNER JOIN [BoatDefectLog] ON Owner.MemberID=BoatDefectLog.MemberID" & _
"ON MemberID.Owner = MemberID.BoatDefectLog) "

" FROM Owner INNER JOIN BoatDefectLog ON Owner.MemberID = BoatDefectLog.MemberID WHERE Surname = '"

userInput = TextBox1.Text
SQL = String.Concat(SQL, userInput)
SQL = String.Concat(SQL, "'")

da = New OleDb.OleDbDataAdapter(SQL, con)
da.Fill(ds, "RoyalYachtingAssociation2")
Dim dataAdapter As New OleDb.OleDbDataAdapter(commandString, con)
dataAdapter.Fill(ds, "RoyalYachtingAssociation2")
End Sub

Private Sub FillControls()

see this example :

"SELECT a.Id_User, a.Password, b.Id_Role, b.Status FROM USERS a join ROLE b on (a.Id_Role=b.Id_Role)"
