Pb with LONG, size exceeds 32767

Question

With ODP.NET 9.2.0.2.102 - ORACLE 8.1.7 I can't read LONG value larger than 32767 characters.
When the size exceeds this limit, the value is truncated at exactly 32767 characters even if InitialLONGFetchSize is set to a larger size.
example of my code : (vb.net 2003)
objCmd = New OracleCommand(sql, m_ObjOracleConn)
objCmd.CommandType = CommandType.Text
objCmd.InitialLONGFetchSize = 200000
value = objCmd.ExecuteScalar()

Answer 1

Thank you. Unfortunately the result is always the same.
I've tried this :
Dim objCmd As OracleCommand
Dim DA As OracleDataReader
dim sql as string = "SELECT ROWID,OPH FROM A_GA WHERE DICO = 'G' AND DOSSIER = '@' AND ID1 = 'TEST' AND NO=0 AND RUB = '0000'"
objCmd = New OracleCommand(sql, m_ObjOracleConn)
objCmd.InitialLONGFetchSize = 200000
m_ObjOracleConn.Open()
DA = objCmd.ExecuteReader()
If DA.Read() Then
Return DA.GetString(1)
Else
Return String.Empty
End If
The length of the result string is still 32767
I've added objCmd.AddRowid = True -> result.length = 32767
objCmd.ExecuteScalar() -> result.length = 32767
parameterized call-> result.length = 32767
What's wrong with my code ?
