Hi im trying to use this sql select statement in my app but when i call it the app says 'invalid attempt to read when no data is present'.

here is my statement:

        myCommand = New SqlCommand("SELECT TOP 1 prospector.ID, prospector.adviserID, prospector.cMonth, prospector.cYear " & _
        "FROM prospector ", objConnection)

if i run it without the quotes in MSSM is works perfectly and produces just 1 row. Do i need to change something when i use top 1 in my vb app?

Specify the Schemaname in front of the table name like schemaname.prospector.

        myCommand = New SqlCommand("SELECT TOP 1 ID, adviserID, cMonth, cYear " & _
        "FROM [myo].[dbo].[prospector] ", objConnection)

SqlCommand are used to INSERT, UPDATE and DELETE methods and not SELECTS. You have to use an SqlDataReader and do an ExecuteReader instead SqlCommand
