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 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''

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 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>

How to compare dates in Crystal Reports 2008

Hello,
I cannot figure out how to compare the dates in the Crystal reports.
I need all dates that are in the future to be displayed with the green font.
So in the formula for the font for this texbox I've tried to use different
formulas like:
If DateDiff("d", CurrentDate, {DevelopmentTracking_SELECT.Anticipated}) > 1
Then
     crGreen
or
If {DevelopmentTracking_SELECT.Anticipated} > CurrentDate Then
     crGreen
(where DevelopmentTracking_SELECT is the stored procedure, and Anticipated
is a date field).
None of them worked. All dates are treated like they were in the past
comparing to the CurrentDate. If I reverse these formulas like:
If {DevelopmentTracking_SELECT.Anticipated} < CurrentDate Then
     crGreen
then all dates turn to green, otherwise they always stay black.
What could be a problem here?
I would appreciate your help.
Thank you.

OK, got it, thank you. It worked.
However, I also need to use another field value which is not on the report, like this:
If CurrentFieldValue < CurrentDate And {DevelopmentTracking_SELECT.Completed} = False Then
crRed
DevelopmentTracking_SELECT.Completed is not on the report.
Is it possible to use it with the cross-tab?

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?

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 compare data between two tables?

Hi,
My team is trying to develop a SAP data migration tool (DMT) using ABAP.
One of the functionalities in the DMT is to validate the data in the staging area against the loaded SAP data.
The tables in the stagin area are customer tables (i.e. user-defined tables starting with Y, Z).
How do I compare the data in the staging area against data that are loaded into SAP tables? Are there some built-in SAP functions to do this? Or, are there some better ways of doing this (e.g. instead of comparing against data in the SAP tables, we compare with some INTERNAL tables)?
Any help would be greatly appreciated, thanks!

Hi Kian,
Use <b>SCMP</b> transaction to compare data between two tables and you can not use this for comparing internal tables.
Thanks,

I'd probably use a database for this, if there's any quantity of data involved here. Import from Excel into {SQLite, MySQL, PostgreSQL, FileMaker, maybe Core Data}, or pick your preferred key-value store, keep your data in the database, then export or (via ODBC/JDBC) then access live database data from within the spreadsheets.
Alternatively and if you're looking at small quantities of data (say, less than 10,000 entries, or less than a thousand depending on the language), then just use whatever passes for a key-value store in your preferred scripting language {Python, bash, Lua, or maybe php, AppleScript or Java} and use that. Export Excel to CSV {gag} or XML, then load that into Python and process as needed, then write out CSV {gag} or XML.
AppleScript is a scripting language for GUI applications, and also useful for processing events. If you're not doing that sort of stuff, then there can be other choices, and other choices can often have extensive frameworks and libraries for common tasks.
Sooner or later, most everybody runs into a wall when using a spreadsheet... Various folks have encountered those limits and have migrated from spreadsheets to FileMaker databases, and now use a database as the central store for their operations — and that's the other issue that can arise with spreadsheets... Where's the canonical data?

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)?

How to compare data from 2 different time periods

Hi folks,
I have a question on approach to a problem. I want to be able to compare data from a common db, but for 2 different time periods. For example I want to see the number of occurences of an instance in my data for today and compare it against occurences a week ago today. What's the best approach for this kind of problem? Is this done with 2 separate queries from 2 sub reports and then compared some how? Any comments on this approach or an other are appreciated.
TIA bvd

Follow these steps:
1) Bring your first time period in your main report. This will be your first query.
2) Bring your second time period in a subreport. This will be your second query.
3) Bring the values from your subreport into your main report using shared variables.
4) Lastly, compare the results using formulas in your main report.
I hope this information proves useful.

How to compare dates using javascript?

Hi,
I have to compare dates using javascript. The dates are in format "mm/dd/yy" for eg "10/09/06".
I have written a script to compare the dates but the problem I 'm facing is with the year.
For example if I compare "10/09/06" with "10/04/98", then "10/04/98" is coming out to be greater than "10/09/06" because it is considering year "98" to be greater than "06".
Please advice/suggest.
Thanks in advance...

Dude, you're here in a Java forum, not in a Javascript forum. Those are two entirely different languages.
The answer in Java is to use java.text.SimpleDateFormat to convert String to Date and use java.util.Date and/or java.util.Calendar to compare dates.

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!!!

Basic XML Publisher Question: How to access tags in the higher levels?

Hi All,
We have a basic question in XML Publisher.
We have a xml hierarchy like below:
<CD_CATALOG>
<CATALOG>
<CAT_NAME> CATALOG 1</CAT_NAME>
<CD>
<TITLE>TITLE1 </TITLE>
<ARTIST>ARTIST1 </ARTIST>
</CD>
<CD>
<TITLE> TITLE2</TITLE>
<ARTIST>ARTIST2 </ARTIST>
</CD>
</CATALOG>
<CATALOG>
<CAT_NAME> CATALOG 2</CAT_NAME>
<CD>
<TITLE>TITLE3 </TITLE>
<ARTIST>ARTIST3 </ARTIST>
</CD>
<CD>
<TITLE> TITLE4</TITLE>
<ARTIST>ARTIST4 </ARTIST>
</CD>
</CATALOG>
</CD_CATALOG>
We need to create a report like below:
CATALOG_NAME     CD_TITLE     CD_ARTISTCATALOG 1     TITLE1     ARTIST1
CATALOG 1     TITLE2     ARTIST2
CATALOG 2     TITLE3     ARTIST3
CATALOG 2     TITLE4     ARTIST4
So we have to loop at the level of <CD> using for-each CD. But when we are inside this loop, we cannot access the value of CAT_NAME which is at a higher level.
How can we solve this?
Right now, we are using the work-around of set_variable and get_Variable. We are setting the value of CAT_NAME inside an outer loop, and using it inside the inner loop using get_variable.
Is this the proper way to do this or are there better ways to do this? We are running into troubles when the data is inside tables.

you can use
<?../CAT_NAME?>copy past to your template
<?for-each:CD?> <?../CAT_NAME?> <?TITLE?> <?ARTIST?> <?end for-each?>

How to automat. copy configuration of higher level material to sub-item

Hi Experts,
I have Make to Order Scenario.
My customer wants the configuration of the non-phantom sub-items in the sales order to be automatically copied from the configuration of the higher level material.
I have added the ZCOPY function module( to copy configuration) to the configuration profile of the sub-item but the program flow does not go through the function module because sub-item has a link to higher level material.
If I go to the configuration of the sub-item in VA02, it appears a message u201CThe item configuration can only be changed by that higher level materialu201D. All chosen characteristics of the higher level material are shown, actually configuration of the higher level material is shown because of the link. But in CU44 of that sub-item, sales order no
Characteristics are selected.
Any suggestion how and where to place automatic copy of the configuration of the higher level material to the sub-item?
Kind regards,
Danijela Zivanovic

    Thank you for your comments. I know that adding A's routing to B is the best simple way to solve the problem. But as a little part of our global firm, our plant can't change master data related to cost calculation so easy. Every chance should be verified by global cost control team. And the routing is B is already very complex, we don't want to make it more complex.
    As same, create another material code is not available too because this should be considered by global team.
    Currently, we are creating production order for A separately. And A was looked as a component in B's production order. So, there are 2 production orders should be deal with. In fact, these two orders should be done at same time. It was complained by shop floor that too much order confirmation work to do. Warehouse complains too. And further, this way disturbs production planning very much due to the system will not always plans these 2 orders together.

Robbie
