SET @rownumber = 0;
update mytable set Moneyorder = (@rownumber:[email protected]+1)
order by MoneyOrder asc
या इसे एक ही प्रश्न में करने के लिए आप कोशिश कर सकते हैं
update mytable target
join
(
select id, (@rownumber := @rownumber + 1) as rownum
from mytable
cross join (select @rownumber := 0) r
order by MoneyOrder asc
) source on target.id = source.id
set Moneyorder = rownum
