Im not good in querying. I would like to ask if this query works.
I want to retrieve starttime, endtime and sessioncost from the table SESSION of my database. my program will be an autorun. IT MEANS THAT ID SHOULD BE SELECTED AUTOMATICALLY WHEN IT RUNS. 

Dim sql As String = "select STARTTIME, ENDTIME, SESSIONCOST from SESSIONS where CLIENTID =  (?)"

I cant post the image because it requires more than 10 reputation. Im sorry.. If you have a better code/query, I appreciate your help. 🙂
thank you so much for your feedback..

    First count CLIENTID into one variable

    sql query for count

    select count(ClIENTID) from SESSIONS;

    now store this count value into some variable

    Dim count_variable As Integer

Dim MyValue As Integer
Randomize   ' Initialize random-number generator.
MyValue = CInt(Int((count_variable * Rnd()) + 1))

    Now once you get the random value

    Dim sql As String = "select STARTTIME, ENDTIME, SESSIONCOST from SESSIONS where CLIENTID = MyValue"

    By this way you can get random results within the count of clientids
