java - How to get a set number of rows from a ResultSet -


i need 2 current items in result set , wondering best way without break. realize rs.next() returns true or false , tried stop counter failed. have @ moment:

while(rs.next()){     string name = rs.getstring("name");     string starttime = rs.getstring("starting_time");     string endtime = rs.getstring("ending_time");     string date = rs.getstring("directory");     string loc = rs.getstring("location");      htmlbuilder.append("<li><a href='public/committees/calendar'>"+ name+"<br>");      htmlbuilder.append(date +"  "+starttime+" - "+endtime+"</a> <!-- link/title/date/start-end time --><br>");     htmlbuilder.append("<strong>location: </strong>"+loc+"<br>");     htmlbuilder.append("</li>");         }        html = htmlbuilder.tostring();

as can tell, returns resultset need first 2 entries.

here correct query:

select  to_char(to_date(to_char(x.starting_date), 'j'),'mm/dd/yyyy') start_date,  to_char(to_date(to_char(x.ending_date), 'j'),'mm/dd/yyyy') end_date,  to_char(to_date(to_char(x.starting_date), 'j'),'yyyy-mm-dd') directory,  x.starting_time,  x.ending_time,  x.description,  x.description location,  x.name,  x.short_name,  x.add_info_url,  x.contact_name,  x.contact_info calitem x, calendar x, calitemtypes x x.calendar_id = x.calendar_id , x.short_name ? , x.style_id = 0 , x.starting_date > to_char(sysdate-1, 'j') , x.item_type_id = x.item_type_id , rownum <= 3 order to_date(to_char(x.starting_date), 'j')

adding rownum attribute worked , query ordered before return. help

you should limit query return 2 current rows. can achieved limit clause (exists in mysql, not sure other dbs) , order clause.

there not need add index count rows returned resultset.

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
