Customize JQuery UI datepicker with From and To date

I think you have used the JQuery UI datepicker many times and you have also faced trouble when there are 2 date text-boxes and you have to use datepicker in both with taking care that one text-box date value always less than the 2nd one.


I think you have got my point, what I want to say.
Like you have two date fields named as FROM and TO and FROM date should always less then TO date.


For solving the same you have to make a trick in the datepicker function.
Below is the same you can use.


Just add below three lines to include CSS and JS  in your document head as below.


Head Section:

[sourcecode language=”plain”]

<link rel="stylesheet" href="" type="text/css" media="all" />

<script type="text/javascript" src=""></script>

<script type="text/javascript" src=""></script>



JavaScript Code:

[code lang=”js”]
<script type="text/javascript">


dateFormat : ‘dd/mm/yy’,
minDate : new Date(),
maxDate : ‘+1Y’,
defaultDate: "+1w",
changeMonth: true,
onSelect : function(selected){

var arr = selected.split("/");
var spares = [arr[2], arr[1],parseInt(parseInt(arr[0])+1)];
var joint = spares.join("/");
var minDate2 = new Date(joint);
$("#datepicker2").datepicker("option","minDate", minDate2);




dateFormat : ‘dd/mm/yy’,
minDate : "+1",
defaultDate: "+1w",
maxDate : ‘+1Y’,
changeMonth: true,
onSelect : function(selected) {

$( "#datepicker" ).datepicker( "option", "maxDate", selected );





HTML Code:

[sourcecode language=”plain”]
<table width="100%" border="0" cellspacing="2" cellpadding="2">
<td colspan="2">From Date:</td>
<td><input type="text" value="" name="indate" id="datepicker" /></td>
<td colspan="2">To Date:</td>
<td><input type="text" value="" name="outdate" id="datepicker2" /></td>


For further reference you can go through the JQuery UI library by the below URL.

What is the difference between GROUP BY and ORDER BY in MySql?

What is the difference between GROUP BY and ORDER BY in MySql?


Mostly this question has been asked by the interviewer, even if you have used it many times but at that time generally the guy not satisfied the interviewer by the answer.


Please go through the below and give very appropriate answer and increase your chances of selection.




GROUP BY is used to make the group-set of records based on the fields of the table or you can say GROUP BY keeps related data items together.


GROUP BY clause often used with the aggregate functions (SUM, AVG, MAX) on the columns in a query the other columns should be in group by query, you can use HAVING clause to apply the condition on the group-set that will fetch by the query.


Let’s take an example:
Suppose we have a table student as below.



Id                     Name
01                     Nirmal
98                     Stephen
65                     Mahesh
65                     Hodge
90                     Pamlea
90                     Paul
90                     Shakira


Question 1: Due to some mistake by the programmer, there was some duplicate id for some students. Fetch which id is duplicated and how many times?


[sourcecode language=”plain”]
SELECT Id, count(Id)
FROM tbl_student


Question 2: Fetch which id is duplicated and how many times and the Ids should be greater than 80.

[sourcecode language=”plain”]
SELECT Id, count(Id)
FROM tbl_student
HAVING Id > 80




The ORDER BY clause is used to sort the result-set by a specified column either by ASC or DESC.
By default, ORDER BY clause sorts the records in ascending order.


ASC = Ascending (shortest first)
Desc = Descending (largest first)


[sourcecode language=”plain”]
FROM tbl_student


I think it will make sense?
