I hope this helps you . enter code hereSuggest me on this.. While creating Date ref(java script), text box value should be treated as dd/MM/yyyy format.. , Try this:
code :
var dateString = document.getElementById('<textboxid>').value;
var day   = parseInt(dateString.substring(0,2));
var month = parseInt(dateString.substring(3,5));
var year = parseInt(dateString.substring(6,10));
alert(new Date(year, month - 1, day));
alert(/^(0[1-9]|[12][0-9]|3[01]|[1-9])[- /.](0[1-9]|1[012]|[1-9])[- /.](\d{4})$/.test(dateString));

around this issue There are several potential problems here:
You're not specifying a format You're not specifying a locale You're not specifying a time zone You're trying to cast the return value (which will be a java.util.Date reference) to a java.sql.Date - that would fail
code :
DateFormat df = new SimpleDateFormat("MM/dd/yyyy", Locale.US);
df.setTimeZone(...); // Whatever time zone you want to use
Date journeyDate = new java.sql.Date(df.parse(text).getTime());

this one helps. You must convert your text date to true for any comparison to work.
So (in Access):
code :
Select columns From table Where DateSerial(Mid(jobdate, 7, 4), Mid(jobdate, 4, 2), Mid(jobdate, 1, 2) >= Date()

should help you out Step one is to write a generator that yields date strings in three month increments from a given date string to the present. We can store the initial date in a datetime object, using that to generate the new date strings at every step, and keep the dates from moving past the present. Then we can use calendar.monthrange to find the last days of the given months.
code :
from datetime import datetime
from calendar import monthrange

def dates_from(start):
    date  = datetime.strptime(start, "%Y%m%d")
    today = datetime.today()
    while date < today:
        yield date.strftime("%Y%m%d")
        month = date.month + 3
        year = date.year
        if month > 12:
            year += 1
            month -= 12
        _, day = monthrange(year, month)
        date = datetime(year, month, day)
sql_template = """\
SELECT 
  (SELECT
      PCR.repdte
      FROM 
      All_Reports_{0}_Performance_and_Condition_Ratios as 
      PCR) AS Quarter,
  (SELECT 
      Round(AVG(PCR.lnlsdepr))
      FROM 
      All_Reports_{0}_Performance_and_Condition_Ratios as 
      PCR) AS NetLoansAndLeasesToDeposits,
  (SELECT sum(CAST(LD.IDdepsam as int))
      FROM 
     'All_Reports_{0}_Deposits_Based_on_the_Dollars250,000
     _Reporting_Threshold' AS LD) AS 
     DepositAccountsWith$LessThan$250k"""

queries = map(sql_template.format, dates_from("19921231"))
output_string = "\nUNION ALL\n".join(queries)
