hey guys i want to display the data from ResultSet in HTML table .. here is my code while(result.next()){ writer.println('
Solution 1:
Put the last line outside the loop
Solution 2:
How about something like this?
writer.println("<tableBORDER=1CELLPADDING=0CELLSPACING=0WIDTH=100%>"
+"<tr><th>FIRSTNAME</th><th>LASTNAME</th></tr>");
while(result.next()){
writer.println("<tr><td><center>"+result.getString("firstname")+"</center></td>"
+ "<td><center>"+result.getString("lastname")+"</center></td></tr>");
}
writer.println("</table>");
Solution 3:
Steps to convert ResultSet object to HTML content
(1) Import the package in your JAVA class file
(2) Create an object of class type "HtmlReportGenerator"
(3) Set Table Name as a String
(4) Set Column Names as a comma separated String
(5) Call "toHTMLTable()" method with the ResultSet Object,table name and Column Name as parameters
Example:
import frizbee.beach.*;
HtmlReportGenerator hrp=newHtmlReportGenerator();
String columnNames="col1,col2,col3,col4,col5,col6,col7,col8,col9";
String tableName="abcde";
String html=hrp.toHTMLTable(rs,tableName,columnNames);
System.out.println(html);
@SuppressWarnings("unchecked")
publicStringtoHTMLTable(ResultSet rs,String tableName,String columnNames) throws JSONException, SQLException {
ResultSetMetaData rsmd = rs.getMetaData();
int numColumns = rsmd.getColumnCount();
JSONArray json = newJSONArray();
while(rs.next()) {
LinkedHashMap<String, Object> lhm = newLinkedHashMap<String, Object>();
for (int i=1; i<=numColumns; i++) {
String column_name = rsmd.getColumnLabel(i);
lhm.put(column_name,rs.getObject(column_name));
}
json.put(lhm);
}
String[] colNames=columnNames.split(",");
StringBuilder s1=newStringBuilder();
s1.append("<div style=\"font-size:14pt;font-weight:bold;margin:15pt auto;text-align:center\">"+tableName+"</div>"
+ " <table style=\"background:white;border-collapse: collapse;text-align:center;margin:10pt auto;border-radius:4px;border:1px solid rgba(255, 30, 0, 0);width:97%\" width=\"97%\" align=\"center\">" +
" <thead style=\"background:#a6a6a6;color:white\">");
for(int i=0;i<colNames.length;i++) {
s1.append("<th style=\"padding:10pt 2pt;\">"+colNames[i]+"</th>");
}
s1.append("</thead><tbody>");
for (int i = 0; i < json.length(); i++) {
s1.append("<tr>");
JSONObject jsonObj = json.getJSONObject(i);
Iterator<String> keys = jsonObj.keys();
while (keys.hasNext()) {
String key = keys.next();
String val="";
if(jsonObj.isNull(key)) {
val="";
}
else {
val= jsonObj.get(key).toString();
}
s1.append("<td style=\"padding:7pt 2pt;border-bottom: 1px solid black !important;"+bgColor(i)+"\">"+val+"</td>");
}
s1.append("</tr>");
}
s1.append("</tbody></table>");
return s1.toString();
}
privateStringbgColor(int i) {
return i%2==0?"background-color:#ededed":"";
}
