FASTLOAD WITH FIXED WIDTH FILES - response (17) by siddique

I am using Fastload to load some data in to Teradata but it returns 
 No row found for this job in log table SYSADMIN.FASTLOG.

              BEGIN LOADING was successful, but there is no restart info.

              This job cannot be continued or restarted.

I used the script mentioned below:

.sessions 2;

.errlimit 50;

.LOGON dbc/dbc,dbc;

.set record unformatted

DATABASE squid_data;

DEFINE

timestamps (varchar(200)), 

responsetime (varchar(10)), 

IP (varchar(15)), 

tcp_code (varchar(255)),

http_code (varchar(50)), 

bytesreceived (varchar(10)), 

method1 (varchar(10)), 

URL (varchar(1000)), 

username (varchar(150)), 

peerhost (varchar (200)), 

peerstatus (varchar (100)),

contenttype (varchar (50)) 

FILE=access_log.txt;

BEGIN LOADING

squid_data.access

ERRORFILES

Event_ERROR1,Event_ERROR2

CHECKPOINT 10000;

INSERT INTO squid_data.access VALUES

(

:timestamps ,

:responsetime ,

:IP ,

:tcp_code ,

:http_code ,

:bytesreceived ,

:method1 ,

:URL ,

:username ,

:peerhost ,

:peerstatus ,

:contenttype

);

END LOADING;

LOGOFF;
