java时间函数，以及 sql 时间范围查找 代码
String keyword = request.getParameter("keyword");
String timeRange = request.getParameter("timeRange");
String type = request.getParameter("type");
StringBuffer sql = new StringBuffer();

if( (keyword == null)|| (keyword.equals("")) ){
sql.append("title like '%' and ");
}else {
sql.append("title like '%"+keyword +"%' and ");
}
if(timeRange.equals("")||timeRange==null){
sql.append("");
}else{
//Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd kk:mm:ss");
//String now = sdf.format(cal.getTime());
String begintime = "";

select pdt;
this.dataview.DataSource=result.Skip(10).take(10);
