How to compare dates in a select query in open sql

Hi
                   How can I retrieve data pertaining to a specified date using a select query.
I have inserted date using the following code:
String dateString = "2009-03-11";
java.sql.Date date = java.sql.Date.valueOf(dateString);
PreparedStatement stmt =con.prepareStatement("insert into DATEACCESS"
                                                                        + "(DATETEST)"
                                                                        + "values (?)");
stmt.setDate(1,date);
stmt.executeUpdate();
How can I pass this in a select query,the below mentioned query did not fetch me any results.
Select * from DATEACCESS where DATETEST='2009-03-11'

Hi
Has ur date problem resolved ?
If not resolved u can do the following
As u already have sql date today declared . You want to get the data depending on that date
As ur query is
if( today != null)
String query2 = select * from DATEACCESS where DATETEST<= ?
PreparedStatement ps = conn.prepareStatement(query2);
ps.setDate(1,today)
ResultSet rs = ps.executeQuery();
While(rs.next)
////// Here u will get data from query u needed ///
If this also does not work just print the date and check in which format is it returning u .

can i use to_char to compare date
SELECT eno, ename, GREATEST (TBLE.MAX1, TBLE.MAX2) recent_date "

               MAX (TO_CHAR (TBL.date1, 'MM/DD/YYYY HH24:MI') "
               ) MAX1, "

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'

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).

How describe model data and get select in DB throw topLink.
Dema.

So you'll probably have to write a function which uses dynamic SQL to retrieve the desired message text, like this untested one:
CREATE OR REPLACE FUNCTION get_msg(p_db IN VARCHAR2,
                                   p_id IN NUMBER)
   RETURN VARCHAR2
IS
   msg_txt VARCHAR2(4000);
BEGIN
   -- make sure p_db is a valid database link ...
   EXECUTE IMMEDIATE 'SELECT d_msg FROM msg@' || p_db || ' WHERE t_id = :id' INTO msg_txt USING p_id;
   RETURN msg_txt;
EXCEPTION
   WHEN NO_DATA_FOUND THEN
      RETURN NULL;
END get_msg;
/The you can update likeUPDATE mex
   SET t_msg = get_msg(db_id, t_id);Hth, Urs

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.

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:

In order to load a collection or array of data you can use <html:select> with <html: options collection="" name=""/>
here collection attribute refers to the Arraylist or Array of data and name is the name of the Form bean.
Hope this helps...

How to Compare Data length of staging table with base table definition

Hi,
I've two tables :staging table and base table.
I'm getting data from flatfiles into staging table, as per requirement structure of staging table and base table(length of each and every column in staging table is 25% more to dump data without any errors) are different for ex :if we've city column with varchar length 40 in staging table it has 25 in base table.Once data is dumped into staging table I want to compare actual data length of each and every column in staging table with definition of base table(data_length for each and every column from all_tab_columns) and if any column differs length I need to update the corresponding row in staging table which also has a flag called err_length.
so for this I'm using cursor c1 is select length(a.id),length(a.name)... from staging_table;
cursor c2(name varchar2) is select data_length from all_tab_columns where table_name='BASE_TABLE' and column_name=name;
But we're getting data atonce in first query whereas in second cursor I need to get each and every column and then compare with first ?
Can anyone tell me how to get desired results?
Thanks,
Mahender.

This assumes the column names are the same between the staging and base tables. In addition as you add more columns to this table you'll have to add more CASE statements to check the length and update the COALESCE check as necessary.
Thanks!

How to re-write this big SELECT Query with INNER JOINs?

Hi Experts
I have a performance killer SELECT query with an inner join of 3 tables u2013 VBAP, VBAK and VBEP together, which populates records to an internal table INT_COLL_ORD. Based on these records selected, in another SELECT query, records are fetched from VBUK table to the internal table INT_VBUK.
SELECT A~VBELN A~POSNR A~MATNR A~KWMENG A~KBMENG A~ERDAT A~ERZET A~PSTYV D~AUART E~ETTYP E~EDATU

SELECT VBELN UVALL CMGST INTO TABLE INT_VBUK
FROM VBUK FOR ALL ENTRIES IN INT_TAB_RES
WHERE VBELN = INT_TAB_RES-VBELN AND UVALL NE 'A'.
Now, the requirement is:
I want to split this query. Like, first join VBAK and VBUK first. With this selection, go to the inner join of VBAP and VBEP (on key VBELN) to get the results. How can I re-write this Query?
Please help.

But, since neither VBAP nor VBEP contains AUART field, it cannot be fetched through the QUERY#2. So this value is not populated into INT_COLL_ORD through SELECT Query.
Since this field is used in later part of program & that the internal table has no value for this field, it dumps!!
How to include this value into the INT_COLL_ORD?
Plz suggest....

How can i use index in select query.. facing problem with the select query.

Hi Friends,
I am facing a serious problem in one of the select query. It is taking a lot of time to fetch data in Production Scenario.
Here is the query:
SELECT * APPENDING CORRESPONDING FIELDS OF TABLE tbl_summary
    FROM ztftelat LEFT JOIN ztfzberep
     ON ztfzberep~gjahr = st_input-gjahr

      AND rbukrs = st_input-bukrs
      AND racct = st_input-saknr
      AND ryear = st_input-gjahr
      And rzzlstar in r_lstar
      AND rpmax = c_max_period.
There are 5 indices present for Table ZTFTELAT.
Indices of ZTFTELAT:

Can anyone help me out why it is taking so much time and how we can reduce it ? and also tell me if I want to use index number 1 then how can I use?
Thanks in advance.

for both the above table program is taking very less time .... although both the table used in above queries have similar amount of data. And i can not remove the APPENDING CORRESPONDING. because i have to append the data after fetching from the tables. if i will not use it will delete all the data fetched earlier.
Thanks on advanced......

Table_comparison - how to compare data at a high level

Hi,
I have to do data validation at a high level between two tables that I am loading.
I am trying to use table_comparion transform but the problem is that my target table is at a much lower level than at which I want to compare data. So it has many more columns (both key and data fields) than what I want to compare.
Does the output of query transform ( which I am using as input into table_comparion) be in the exact same format as comparion table? If not, then can somebody suggest me something else.
Or how can I compare output of two query transforms ?
Thanks,
Saurabh Bansal

Dear Saurabh,
Not sure if you have already got the solution to this. If yes please close the thread.
If not, i would suggest you can use the validation rule to compare the two tables and then based on the PASS or FAIL result can check what needs to be done on the output.
Do post back if you have got the solution or you need any furthur help or else close the question.
regards,
Den

How to compare Date in the TextField or DateTime with Date/Time field?

Hi All,
I am facing an issue with respect Date comparinson. I tried to look into entire discussions but failed to get the answer.
My issue is: I wanted to comparet Date/time field value with Date value which is in TextField.
The functionality of my form is:
I have dropdown list which lists the registered customer ids binded to XML Datasource. On selection of the customer id from the dropdown I am displaying customer registration date in the TextField or say Date/Time field as below code in dropdown change event.
RegistrationDetails.PurchaseEntry.txtRegDate.rawValue = regDataNode.CREATION_DATE.value; (this is TextField control)
In form I have an Date/Time field in which use will select the date of item purchase. In the validation part I want to make sure that, the purchase date selected in Date/Time field must be greater than the Customer Registraiton Date. I able to compare if the customer selects the date from two different Date/Time fields. But how to compare the dates which one is in Date/Time field and Date is in TextField?
I have tried using Num2Date and Date2Num with "YYYY-MM-DD" format to compare but not succeed!
Can you guys help me in this? Thanks in advance
Regards.

Hi,
Yes, I am able to display the date which I have assigned to the text box. In the message box it show the value as '31/05/2009', since in this format i am assigining the date in the text box.
Here is the code which I am assigning the value:
RegistrationDetails.PurchaseEntry.txtRegDate.rawValue = regDataNode.CREATION_DATE.value;
Do I need to change the format while assigning value in text box?
You have told that, you have attached your test form, nothing is the reply. Can you repost the file?
Regards.

How to compare dates between two items

Hello all,
I am trying to compare dates in two items.
The first item is a computation P45_PAGE_LOADED_TIME
select sysdate from dual;
This essentially keeps track of when the user opened the form. They are accessing data that may become obsolete while they are in the form.
So we have a dynamic action that finds the last_update date from a table. This field is of type date. It is placed in a text field called P45_STATUS.
We then have a notification which we want to fire when P45_PAGE_LOADED_TIME is before P45_STATUS. We tried the following condition
declare
least_date date;
begin
SELECT LEAST(TO_DATE(:P45_STATUS),TO_DATE(:P45_PAGE_LOADED_TIME)) into least_date
from dual;
if least_date = to_date(:P45_STATUS) then
return false;
else
return true;
end if;
end;
Any guidance would be most appreciated.
Thanks

Maybe your better off putting your anonymous block into a plsql function.
A function that you can test. If it works in plsql then you must call it in APEX.
I kinda get a headache when I see that least, to_date, to_date query (although I've seen worse :p)
Make it like:
create or replace function fun_least_date(in_status in varchar2,
                                                           in_page_loaded_time varchar2) return boolean
is
l_status date;
l_page_loaded_time date;
least_date date;
l_return boolean;
begin
l_status := to_date(in_status, 'FORMAT MASK!!!');
l_page_loaded_time := to_date(in_page_loaded_time, 'FORMAT MASK!!!!');
least_date := least(l_status, l_page_loaded_time);
if least_date = l_status then
    l_return := false;
else
    l_return := true;
end if;
return l_return
end fun_least_date;If your sure that your function is correct then use it as a condition for your dynamic action.
Regards
Nico
ps: I haven't tested that function. Be aware that you most correctly enter the format mask you use in APEX. Also before APEX may know about these variables you should set a dynamic action on your items to always submit their value to the server when they change!!!

How to compare Date/time string

I read from datalog file including Date/time string ,and want to query the special Date/time string span ,how to compare the data/time string ?

Hello Joshua,
To compare date/time you have to extract the different components (day, month, year, hour, minute, second) anyway. Why not "convert to seconds"? I think it's easier to compare one number (where you also can do other math, like calc the difference and so on) than to compare seven (?) parameters with some exceptions... If the dates are read from excel (there was a similar thread some days ago), why not convert to seconds in excel (just a format change)?
