Problem with displaying nodes as dates

When I create a node for arcal, it doesn't appear on calendar. When I go on next year (for example 2011) and then go back to previous year, the created node appears as date link on calendar. But when I click on the date, following message is displayed:

user warning: Unknown column 'n.nid' in 'field list' query: SELECT DISTINCT(n.nid) FROM node WHERE type IN ('news') AND status = 1 AND FROM_UNIXTIME(node.created,'%Y') = 2010 AND FROM_UNIXTIME(node.created,'%m') = 4 AND FROM_UNIXTIME(node.created,'%d') = 27 ORDER BY node.created DESC
