reading table using reader ASP.NET and VB - asp.net

Question

I have a view patients page and it shows all patients and there's a link next to each patient which takes you to another page where the user can update the patient's information using textboxes and dropdownlists .. i used query string choose a certain patient and reader command to read from the database ..
The problem is the reader isn't accessing the table at all .. can you help me please?
pid = Request.QueryString("Pateint_ID")
Dim tempQuery As String = "SELECT P.first_name, P.sec_name, P.third_name, P.last_name, P.Gender, PATA.ApplicationStatus," & _
"P.DoB, P.birthplace, P.Nationality, P.patient_ID, P.issue_date, P.issue_place, P.city, " & _
"P.Area,h.Name , h.DialysisCetner, p.Mobile_No, p.Work_phone, p.PhoneNo, p.Zipcode, p.POBox, p.problemWithDialysis" & _
"FROM Association AS A INNER JOIN PatientApplyToAssociation AS PATA INNER JOIN" & _
"patient AS P ON PATA.patient_ID = P.patient_ID ON A.Association_ID = PATA.Association_ID INNER JOIN " & _
"hospital AS H INNER JOIN TreatmentSession AS ts ON ts.Name = H.Name ON p.patient_ID = ts.patient_ID LEFT OUTER JOIN Family AS F INNER JOIN" & _
"Gardian AS G ON F.family_ID = G.GID INNER JOIN Relates AS R ON F.family_ID = R.family_ID ON P.patient_ID = R.patient_ID" & _
"WHERE (P.patient_ID = pid )"
Dim query As String = String.Format(tempQuery, pid)
Dim comm As New SqlCommand(query, con)
Dim reader As SqlDataReader
Try
con.Open()
reader = comm.ExecuteReader()
If reader.Read() Then
txtFirstName.Text = reader("first_name").ToString()
txtFatherName.Text = reader("sec_name").ToString()
txtGrandName.Text = reader("third_name").ToString()
txtFamilyName.Text = reader("last_name").ToString()
rblGender.SelectedValue = reader("Gender").ToString()
txtBirthdate.Text = reader("DoB").ToString()
ddlBirthPlace.SelectedValue = reader("birthplace").ToString()
txtNationality.Text = reader("Nationality").ToString()
txtIDCard.Text = reader("patient_ID").ToString()
ddlIssuePlace.SelectedValue = reader("issue_place").ToString()
txtIssuedate.Text = reader("issue_date").ToString()
ddlAddressCity.SelectedValue = reader("city").ToString()
ddlAddressRegion.SelectedValue = reader("area").ToString()
End If
Catch ex As Exception
MsgBox("somthing's wrong")
Finally
con.Close()
End Try

Based on your last comment, im guessing its an SQL problem. I would first take your query and run it in query analyzer to make sure its valid.
Your query looks incorrect.
After cleaning up your query so it was legible I noticed this
SELECT P.first_name, P.sec_name, P.third_name, P.last_name, P.Gender, PATA.ApplicationStatus,
P.DoB, P.birthplace, P.Nationality, P.patient_ID, P.issue_date, P.issue_place, P.city,
P.Area,h.Name , h.DialysisCetner, p.Mobile_No, p.Work_phone, p.PhoneNo, p.Zipcode, p.POBox, p.problemWithDialysis
FROM Association AS A INNER JOIN PatientApplyToAssociation AS PATA
INNER JOIN patient AS P ON PATA.patient_ID = P.patient_ID ON A.Association_ID = PATA.Association_ID
INNER JOIN hospital AS H
INNER JOIN TreatmentSession AS ts ON ts.Name = H.Name ON p.patient_ID = ts.patient_ID
LEFT OUTER JOIN Family AS F
INNER JOIN Gardian AS G ON F.family_ID = G.GID INNER JOIN Relates AS R ON F.family_ID = R.family_ID ON P.patient_ID = R.patient_ID
WHERE (P.patient_ID = pid )
Notice 2 of your joins dont have ON clauses? Not to mention you have 3 joins that have multiple ON clauses?
