hibernate 小记
1.有日期时如何比较
java.sql.Date beginDate=java.sql.Date.valueOf( "2006-6-1 ");
java.sql.Date endDate=java.sql.Date.valueOf( "2006-6-2 ");

"from table tb where tb.startdate <:endDate and tb.startdate > = :beginDate ";

query.setDate( "beginDate ",beginDate);
query.setDate( "endDate ",endDate);
