Let me know how read adn write the datetime value for create_date and update_date column from csv to teradate table

Answer 1

Using the same script, below things should change for the datetime: (1) The column type should be timestamp. Timestamp(0) would do base from the sample data. (2) In the fastload DEFINE, the field should have a length of 18. (3) In the fastload insert, you can use below code:

:file_CREATE_TS(format 'DDMMMYYYY:HH:MI:SS')
