I want to read how many records in the table, and insert a record with id
field which increment the counter by 1. However, I had the following runtime
on Dim s As Integer = CInt(dr("t")). Since "t" (I want to represent the
count, but just a tempoary variable, not a field in table) doesnt exist in
the table
sqlStmt = "SELECT COUNT(*) As t FROM TimeSlot;"
cmd = New SqlCommand(sqlStmt, conn)
cmd.Connection.Open()

Hi,
i wrote this code for fetching data from a table using a stored procedure.
The connection definition and opening are put in a class.
The actual read of data occurs in code-behind.
My problem with this code:
Invalid attempt to Read when reader is closed at line: While dtreader.Read()

Hello fellow geeks
I have a problem in my database iVB .Net program that is generating 'Error:Invalid attempt to read when no data is present.'
The weird part is that when you call the page from another page the script works yielding the desired records
BUT WHEN YOU CALL THE SCRIPT AGAIN WHEN ATTEMPTING TO CALL THE SAME PAGE (PASSING DIFFERENT PARAMETERS USING QUERYSTRING ) THE QUERY DOESN'T YIELD ANY DATA
