Hi
You can get your date in your action method like
Date newDate=new Date();
Date myDate= wdThis
                          .wdGetYourComponentNameController()
                                  .wdGetContext()
                                       .currentYourNodeNameElement()
                                                       .getYourDateName();
if ( myDate== null) {
         wdContext.currentContextElement().setYourDateName(newDate);
else{...........//continue your other validations or calling other methods}

How to compare date with thr current date

Hi,

what i need to do is comparing this date string with the current date. if my input string is less than current date , then display error message..
how to do this?
regards

Excellent suggestions from all of you people!
finally i got the solution
code is:
import java.util.*;
import java.text.*;
public class TestDate {
public static void main(String args[]){
    TestDate a = new TestDate();
TestDate() {
    String DATE_FORMAT = "dd/MM/yyyy hh:mm:ss";
     Date today = new Date();
     Date myDate=null;
    java.text.SimpleDateFormat sdf =
         new java.text.SimpleDateFormat(DATE_FORMAT);
     try{
     myDate = sdf.parse("01/06/2006 00:00:00");
     }catch(Exception e) {System.out.println(e);}
    Calendar c1 = Calendar.getInstance();
    Calendar c2 = Calendar.getInstance();
    c1.setTime(today);
    c2.setTime(myDate1);
    System.out.print(sdf.format(today));
    System.out.print(sdf.format(c1.getTime()));
    if (c1.before(c2)) {
       System.out.print(" is before ");
    if (c1.after(c2)) {
       System.out.print(" is after ");
    if (c1.equals(c2)) {
       System.out.print(" same as ");

RegardsPoint a) VERY BAD IDEA storing dates as VARCHAR2 on the database. It will only lead to corrupt data in the future.
Point b) When comparing dates, you should compare them as DATE datatype as the database knows how to do comparisons against DATES. If you try and compare them as VARCHAR2 then you will most likely end up with incorrect comparisons.
If you must have varchar2 storing of your dates/times (there's absolutely no reason to though)... you want...
TO_DATE(:entered_date,'YYYY/MM/DD HH24:MI:SS') BETWEEN TO_DATE(DATEFROM,'YYYY/MM/DD HH24:MI:SS') AND TO_DATE(DATETO,'YYYY/MM/DD HH24:MI:SS')
e.g.
TO_DATE('20080815 13:23:33','YYYY/MM/DD HH24:MI:SS') BETWEEN TO_DATE(DATEFROM,'YYYY/MM/DD HH24:MI:SS') AND TO_DATE(DATETO,'YYYY/MM/DD HH24:MI:SS')

How to select columns with null values

HI
In my table ‘A’ I have 10 columns and 30,000 records. I need all those columns whose value is null for all the records.
For example in the below table column 'suffix' is null for all the records. So I want column suffix to be selected.
Name Suffix Street
James 1100 Washington street
Richard 273 GEORGIA ST
Arnold 3018 OAKHILL AVE
MICHAEL 834 E 161ST ST
Joseph 410 PINE AVE
Thanks in advance

True...
But, i think here null needs to handle otherwise it will again throw some error like this ->

Import data with nulls in Desktop Intelligence

Hello,
I have data with null values (in a measure). If I export the data as CSV it shows null values as #EMPTY. If I use that as a datasource, it loads #EMPTY as 0 (zero).
Is there a way to make desktop intelligence recognize null values? I tried to remove the #empty and just leave the column empty, it still loads as a numeric zero.
Same (actually worse) for XML. It seems if I export my data to XML it can not use that as a datasource. Odd. So I created the following XML file:
<?xml version='1.0' encoding='UTF-8'?>
<data>
<item key="AAAAAEUK" value="130" category="A" />
<item key="AAAACGDC" value="66" category="A" />
<item key="AAAADNJP" value="56" category="A" />
<item key="AAAAFWRQ" value="222" category="A" />
<item key="AAAAGITU" category="B" />
</data>
I would expect the value field to be null for the last row. But the values turns out to be 222! If I try to put anything else, an empty string "", "#EMPTY", "null", it is always returned as 0.
This is a problem because 0 an null are differnt when computing averages.

Hi Florian,
What is the source of your csv data?
If I have a table in excel with empty cells, the data goes into the .csv as nothing so your example would look like
Item key,value,category
AAAAAEUK,130,A
AAAACGDC,66,A
AAAADNJP,56,A
AAAAFWRQ,222,A
AAAAGITU,,B
This reads in just fine in DeskI (shows #EMPTY in the view data, treats it as such in the report).
So I would look to get the data generated in right way, then DeskI can handle it, no problem.
If all else fails, just run a search&replace and change ,#EMPTY, to ,,
BTW if you have an alphanumeric value in a column where DeskI already decided there should be numeric,
it will read in as 0, that is why the #EMPTY string value got transformed to zero.
Good luck,
Marianne

JDBC MS Access--- cannot extract entry with null value with data type Meta

I'm trying to extract a data entry with null value by using JDBC. The database is MS Access.
The question is how to extract null entry with data type memo? The following code works when the label has data type Text, but it throws sqlException when the data type is memo.
Any advice will be appreciated! thanks!
Following are the table description and JDBC code:
test table has the following attributes:
Field name Data Type
name Text
label Memo
table contents:
name label
me null
you gates
Code:
String query = "SELECT name, label FROM test where name like 'me' ";
ResultSet rs = stmt.executeQuery(query);
while (rs.next())
String name = rs.getString("name");
rs.getString("val");
String label = rs.getString("label");
System.out.println("\t"+name+"\t"+label);
catch (SQLException ex)
System.out.println(ex.getSQLState());
System.out.println(ex.getErrorCode());
System.out.println("in sqlexception");
output:
C:\Temp\SEFormExtractor>java DBTest
yet SELECT name, label FROM test
null
0
in sqlexception

The question is how to extract null entry with data type memo?Okay, what you need to do is this:
if (rs.getString("val") == null)
// do something
}This way, when it's a null value, you can check it first, and then handle it how you want, rather than getting an exception.

How to create a dimension object in SAP BW Unv with Null value

Hi Thilo,
so the only common item is Material then - correct ?

Material                                                                                Material
dummy key figure (why?)                                                                Company Code

Is this something you regular have to do ? what about a MultiProvider ?
did you try "merged dimensions" in the Web Intelligence Report ?

How to compare date which is greatest date

iam new to sql
how to compare date which date is greatest date with example
can i use to_char to compare date
SELECT eno, ename, GREATEST (TBLE.MAX1, TBLE.MAX2) recent_date "
               FROM (SELECT TBLA.eno, TBLA.ename, "
               MAX (TO_CHAR (TBL.date1, 'MM/DD/YYYY HH24:MI') "
               ) MAX1, "
               MAX (TO_CHAR (TBL.date2, 'MM/DD/YYYY HH24:MI') "
               ) MAX2 "
               FROM dual TBL, dual2 TBLA
in above query if any one of the date having null value then recent_date is showing 'null'
and also it showing wrong value
example
date1='08-22-2009' and date2='01-23-2010' then it showing wrong recent_datel ike='08-22-2009'
as according my knowledge it is comparing with month it sholud not be like this wat i have to do pls explain with example my o/p should come for recent_date like =''01-23-2010''
Edited by: user9112274 on Aug 27, 2010 5:31 AM

Hi,
there are numerous ways to compare dates, i give you some examples:
with data_Sample as
(select to_date('01-jan-2001','dd-mon-yyyy') d1, to_date('01-mar-2002','dd-mon-yyyy') d2, to_date('03-feb-2002','dd-mon-yyyy') d3 from dual)
select greatest(d1,d2,d3) from data_Sample
GREATEST(D1,D2,D3)
3/1/2002
with data_Sample as
(select to_date('01-jan-2001','dd-mon-yyyy') d1 from dual union all
select to_date('01-mar-2002','dd-mon-yyyy')   from dual union all
select to_date('03-feb-2002','dd-mon-yyyy') from dual)
select max(d1) from data_Sample
MAX(D1)
3/1/2002
declare
d1 date :=to_date('01-jan-2001','dd-mon-yyyy');
d2 date :=to_date('01-jan-2001','dd-mon-yyyy');
begin
if d1>d2 then
dbms_output.PUT_LINE('d1 greater than d2');
else
dbms_output.PUT_LINE('d1 less or equql than d2');
end if;
end;
output:
d1 less or equal than d2now concerning your question:
>
can i use to_char to compare date
>
If you have date data types : don't convert them.
if you have no choice, use something like:
if to_char(d1,'YYYYMMDD') > to_char(d2,'YYYYMMDD') then
else
end if;Take care when you convert a date into a char format it becomes string comparison (with all it implies) (It's the reason why i've use an explicit mask format).

Need help with NULL values in Crosstables

Hello everybody,
I need some help with NULL values and crosstables. My issue is the following:
I have a query (BW - MDX-Query) that gives me turnover measures for each month. In Crystal Reports I choose crosstable to display this whereby I put all month in columns and all turnover-measures in rows. Each month that has a value (measures are not empty) is chown in the crosstables rows. So far so good. The problem occures when there are month that actually have no values (measures are empty). In that case these months are not chown in columns. But I need CR to display these columns and show the value 0. How can I do that?

Hi Frank,
Cross tab shows the data based on your column and these column fields are grouped and based on the group it will show your summaries.
If there is no data for any of your group it will not display that group. In this case you will have to create a standard report which should look like cross tab and to get zero values you need to write formulas .
Example if you want to display Moth wise sales :
if Month() = 01 Then
sum() else 0
Now this formula will check if your month is Jan, then it will sum up the values else it will display zero value.
This is possible only through standard report not with Cross Tab.
Thanks,
Sastry

How to compare date and time together

Hi,
How to compare Date and Time together?
For example in a database table there are two fields rundate and runtime. I want to compare these two with perticular date and time in the program. Like, I want to pull all the records where the records's date and time are less than a perticular date and time in the program.
Hope the question is clear...
Thanks.
Kavita

Hi Kavita
There is no as such Date and Time Comparision FM in Standard SAP But You can define your own like this
<b>FUNCTION ZAV4_COMPAREDATETIME.
""Lokale Schnittstelle:
*" IMPORTING
*"     REFERENCE(DATE1) TYPE DATS
*"     REFERENCE(TIME1) TYPE TIMS
*"     REFERENCE(DATE2) TYPE DATS
*"     REFERENCE(TIME2) TYPE TIMS
*" EXPORTING
*"     VALUE(TWOISMORETOPICAL) TYPE C
twoismoretopical = ''.
if date2 > date1.
    twoismoretopical = 'X'.
else.
     if date2 = date1 and time2 > time1.
       twoismoretopical = 'X'.
     endif.
endif.
ENDFUNCTION.</b>

Even accounting for the formatting, I'm not sure I even understand the question. It could be any number of different problems or non-problems.

How do I set a NULL value for the parameter field

Hi
I've another question. I'm going to set single values for parameter fields.
// e.g. set today for StartDate parameter field
fc.setCurrentValue("", "StartDate", new Date());
It should be possible to set a NULL value for date parameter fields.
fc.setCurrentValue("", "StartDate", (Date)null);
But this do not work. How do I set a NULL value correctly?
Thank you in advance.
Best regards,
Thomas

First question - is it a stored procedure parameter?
You can't set a regular parameter field value to a null value.
There was an issue with old version of the JRC, where it was allowing null to go through, but had unexpected behavior at times.

How does APEX check for null values in Text Fields on the forms?

Hello all,
How does APEX check for null values in Text Fields on the forms? This might sound trivial but I have a problem with a PL/SQL Validation that I have written.
I have one select list (P108_CLUSTER_ID) and one Text field (P108_PRIVATE_IP). I made P108_CLUSTER_ID to return null value when nothing is selected and assumed P108_PRIVATE_IP to return null value too when nothign is entered in the text field.
All that I need is to validate if P108_PRIVATE_IP is entered when a P108_CLUSTER_ID is selected. i.e it is mandatory to enter Private IP when a cluster is seelcted and following is my Pl/SQL code
Declare
v_valid boolean;
Begin
IF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := FALSE;
ELSIF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := FALSE;
END IF;
return v_valid;
END;
My problem is it is returning FALSE for all the cases.It works fine in SQL Command though..When I tried to Debug and use Firebug, I found that Text fields are not stored a null by default but as empty strings "" . Now I tried modifying my PL/SQL to check Private_IP against an empty string. But doesn't help. Can someone please tell me how I need to proceed.
Thanks

See SQL report for LIKE SEARCH I have just explained how Select list return value works..
