> Is the SP parametr sub_type text? Ok it was the problem thanks !
An other little question in the sp one paremeter is BLOB SUB_TYPE 0 SEGMENT SIZE 80. and when i add a parameter : cmd.Parameters.Add("@PropertyValuesBinary", FbDbType.Binary,buf.Length).Value = buf I have an error : arithmetic exception, numeric overflow, or string truncation because buf is empty but not null !
