- change_col_2 got changed on 2013-08-01 08:00.00.000000 from lks to txh so its value earlier to 2013-08-01 08:00.00.000000 should be lks
- change_col_3 got changed on 2013-08-01 08:00.00.000000 from SPACE(NO VALUE should be treated as NULL) to fdy so its value earlier to 2013-08-01 09:00.00.000000
should be NULL
- same as change_col_2 for change_col_4 & change_col_5
Thank you.
