I managed to work out the solution:
copy table test_tbl (uuid=char(0)comma, vid=char(0)comma, isvalid=char(0)nl) from 'C:\TEMP\test_tbl.csv'
'1111','id1',0
copy table test_tbl (
x=d1, /* remove 1st quote 'd0''' or d1 */
uuid='c0''', /* get data upto first quote */
x1=d2, /* remove quote and comma before vid x1='d1' or d1 :: use d1 to remove 1 char etc */
vid='c0''',
x4=d1,
isvalid=c0nl
) from 'C:\TEMP\test_tbl.csv'
Hope this help someone like me
