Data compare

Hi
I would like to run below query on all tables, however it doesnt work on clob and long datatypes
select * from owner.table_name
minus
select * from owner.table_name@remote_db;
from dba_tables
where owner in ( '....');
ORA-00932: inconsistent datatypes: expected - got CLOB
How can I compare the data of clob and long datatypes using dblink ?

you can not pass clob data over a dblink. you can use plsql to help if it is necessary. you can create a package and describe a cursor in it, then write a function which will return next 4000 char of clob and you can get all clob data using this. why do you want to compare clobs ? what is your purpose, what data is in clob ?

SQL Server Data Compare doesn't retrieve table list

I'm trying to do a data compare in Visual Studio 2013. I have chosen my source and targets and successfully tested the connection to each of them in the connections dialog.
When I choose next, there's a few seconds delay as though the compare tool is checking with the source and target and then it shows a dialog with what to compare. There is a checkbox next to Tables and next to Views. Those are the only two options
shown.
What should be in this dialog, left of Tables and Views, is an arrow to expand them and show the list of tables and views in the source database. The arrow is missing and I cannot expand any list of tables or views. There's just nothing shown
to compare.
When I click Next again, the compare appears to run but when complete it reports that zero tables or views were compared - under the circumstances this is as expected because the previous dialog did not allow me to check any tables to compare.
Why am I not getting the arrow to expand the list of tables? What's wrong with Data Compare?
Thanks,
Dale

Hi Dale,
>>In your image you show a primary key value in comparison key but my tables did not have a primary key assigned
>>Is the comparison key requirement by design?
I repro it, I get the same issue as yours, if no key, we couldn't compare the tables.
Like the document here:
https://msdn.microsoft.com/en-us/library/dn266029%28v=vs.103%29.aspx?f=255&MSPPError=-2147217396
https://msdn.microsoft.com/en-us/library/aa833428(v=vs.100).aspx
Requirements
When you compare data in a table or view, the table or view in the source database must share several attributes with a table or view in the target database. Tables and views that do not meet the following criteria are not compared and do not appear
on the second page of the New Data Comparison wizard:
Tables must have matching column names that have compatible data types.
Names of tables, views, and owners are case-sensitive.
Tables must have the same primary key, unique index, or unique constraint.
Views must have the same unique, clustered index.
You can compare a table with a view only if they have the same name.
Each object has a key or an index that determines the other objects to which it corresponds. However, each table or view can have more than one primary key, unique index, or unique constraint. Therefore, you might want to specify which key, index,
or constraint to use.
As my understanding, it would have the specific requirements.

Jack

Hi Nicolas. It sounds like what you want is to enable replication on your database.
Here is the main help page

JSTL Date Compare Question

I am using JSTL to parse an xml feed (news articles) and need to restrict the articles I get back in the xml to todays date. On another page I am working on I have to restrict the articles to todays date - 7 days (one week). I understand how to parse and format dates with jstl, but am stuck on doing date compares like this. The date I have to restrict on in the xml feed is called <pubDate>. If anyone could help me out with using JSTL to parse and handle these date ranges that would be great. Here is a portion of the xml I am dealing with:

seems to work OK.

Where's Data Compare?

I've been away from the Microsoft stack for a few years doing Java but I have kept up my MSDN subscription and still have all the tools.
Somewhere, while I wasn't looking, it appears that Data Dude (the Database Pro version/tools in Visual Studio, has disappeared. Now I find myself trying to do a data compare between two tables in the same database, even tried duplicating the problem
across two different databases, and I can't get a data compare to work.
I downloaded the SQL Server Data Tools - both editions: SQL Server and Visual Studio - and I find the data compare on the Visual Studio version - but not at all like the current VS2013 blogs and instructions present it. I was able to add the two connections
I need and run the compare but there are no results. The compare window says there were 0 tables or views compared.
What gives? What do I need to do to get a data compare, either in two separate databases or two tables in the same database, to work? Please Help!

Thanks, Joe. I found the menu item; it's not where it was in earlier versions where there was a Data menu. You're right about the same-DB compare. I had to do just as you said, create a new DB and copy one table there.
The other change between the early, red-gate-based, data compare in Visual Studio is that now you must have a primary key defined on both tables. My tables were throwaway tables just for purposes of this test and didn't have primary keys assigned.
I didn't get a compare until I added the primary keys.
Right, you must have a primary key so that Data Compare knows which rows to compare. If you don't have a primary key the table name will not come up in the list of tables available for comparison.

Oracle.jbo.domain.Number / Date comparable ?

Hello,
I'd like to know whether there was a plan to make the oracle.jbo.domain.Number and oracle.jbo.domain.Date classes implement the Comparable interface?
That would save some unnecessary wrapping code...
Thanks in advance,
Remi

I just want to push this Idea, since it is hard to understand, why such a simple interface is not implemented for such a basic class. It would make a lot of things much easier.

Hi,

hi ,
here are the details
CURRENT_MONTH is date datatype in PLAYER_MONTHLY_SUMMARY table TO_DATE, as the name implies, converts something TO a DATE . If current_month is already a DATE, you don't need to convert it to a date.
Besides, the 1st argument to TO_DATE is supposed to be a VARCHAR2. Don't use a DATE where a VARCHAR2 is expected.
and date range is from next_run_date where my next_strt_date and next_end_date both are date datatype
instead of this below query
(TO_DATE(PLAYER_MONTHLY_SUMMARY.CURRENT_MONTH, 'DD-MON-YYYY') BETWEEN
TO_DATE('01-MAR-2012', 'DD-MON-YYYY') AND
TO_DATE('31-MAR-2012', 'DD-MON-YYYY')
if i try below one then it worked
PLAYER_MONTHLY_SUMMARY.CURRENT_MONTH BETWEEN
TO_DATE('01-MAR-2012', 'DD-MON-YYYY') AND
TO_DATE('31-MAR-2012', 'DD-MON-YYYY')
is this approach is rightYes, that's comparing a DATE (current_month) to other DATEs (the results of TO_DATE).
Remember that all DATEs in Oracle include hours, minutes and seconds. If the hours, minutes and seconds of current_month are always 00:00:00 (for example, if current_month is always populated with TRUNC (some_date, 'MONTH')) then the comparison above is okay. But if current_month can be something like 6:52;31 on March 31, 2012, then it will fail the condition, becuase the upper end of the range is
TO_DATE('31-MAR-2012', 'DD-MON-YYYY') which is 00:00:00 on March 31, 2012. To include current_month that is any time of day on March 31, you'd have to do something slightly diferent, such as
PLAYER_MONTHLY_SUMMARY.CURRENT_MONTH BETWEEN TO_DATE ( '01-MAR-2012'     -- Default time, 00:00:00, is okay here
                                                , 'DD-MON-YYYY'
                          AND     TO_DATE ( '31-MAR-2012 23:59:59'
                                                , 'DD-MON-YYYY hh24:mi:ss'
                                    ) or
     PLAYER_MONTHLY_SUMMARY.CURRENT_MONTH >= TO_DATE ( '01-MAR-2012', 'DD-MON-YYYY')
AND PLAYER_MONTHLY_SUMMARY.CURRENT_MONTH < TO_DATE ( '31-MAR-2012', 'DD-MON-YYYY') + 1

Best Practice Question for Date Compares

Hello,
I'm far from an expert on Oracle and PL/SQL, so I may have this all wrong. I'm working on some selection scripts, and the guy that wrote these before me likes to convert parts of dates to numbers in order to do a compare. It seems to me a trunc(date, part) would be much more efficient. Can anyone confirm my thoughts here?
I'm seeing this a lot:
AND TO_NUMBER (TO_CHAR (scheduleddate, 'YYYY')) = TO_NUMBER (TO_CHAR (SYSDATE - 1, 'YYYY'))
Seems to me that I'd be better off just doing:
trunc(scheduleddate, 'YEAR') = trunc(SysDate, 'YEAR').
Does that make sense?
Thanks!
Chad

however , you might want to play around with it a bit to confirm you get the behavior you want in your context. I've not had much reason to use trunc, and in testing a few things just now to reply to admin1, I got some results that surprised me. Another little learning project for me now.
But I stand behind the essence of my original reply. The guy that wrote your original code was jumping through too many hoops (transform functions).

Simple quesstion - Date compare

Hi, I would like to ask how to compare a date with current date in Java.
I tried date.equals() method, but it compare the date and time. However I want to compare the date only. (without time). Thank you very much!

There are many ways to approach this problem. Two off the top of my head:
(1) Use java.text.SimpleDateFormat and put both dates into the same format. Make sure your format only includes the pieces you care about (MM/dd/yyyy for example). Then do a String compare (strObjA.equals(strObjB)) on the resultant output.
(2) Create a java.util.GregorianCalendar object using the times from the date objects. Then use various accessor methods on that object to retrieve the year, month, and day and compare each.
Both of these classes are documented in the java standard APIs.
Hope this helps.

Read Year from System Date & Compare - Assistance required

Hi All,
I am trying to read only the year part from the system date & then checking if any entry exists in EKKO table (EKKO-BEDAT) for the year. I think i am making an error in my data declaration for V_YEAR & in my select statement (EKKO~BEDAT LIKE V_YEAR), not sure how to compare only the year part, can someone help.
DATA:
    V_EBELN TYPE EKPO-EBELN,
    V_YEAR TYPE SY-DATUM.
CLEAR: V_EBELN, V_YEAR.
*Read year from system date
V_YEAR = SY-DATUM+0(4).
CONCATENATE '%' '%' '%' '%' V_YEAR INTO V_YEAR.
*Select section
SELECT SINGLE EKPO~EBELN INTO V_EBELN
FROM EKPO
INNER JOIN EKKO
    ON EKPOEBELN = EKKOEBELN
INNER JOIN LFM1
    ON EKKOLIFNR = LFM1LIFNR
   WHERE EKKO~LIFNR = LFM1-LIFNR
     AND EKKO~BEDAT LIKE V_YEAR
     AND EKPO~LOEKZ = SPACE.

Hi Sougata,
Thanks for the inputs, but it is not working:
Move:      sy-datum(4) to v_begda, -> This reads the system year 2008
        '0101'     to v_begda, -> This changes 2008 to 0101
        sy-datum(4) to v_endda, -> This reads system year i.e. 2008
        '1231'     to v_endda. -> This changes 2008 to 1231
Also in the select statement
AND EKKO~BEDAT between v_begda and v_endda
This would not work, as EKKO-BEDAT is in year month date format.
So can you please clarify why we are assigining 0101 & 1231 & also how we can compare only the year in EKKO-BEDAT with System Year
Update
I tried to
concatenate '0101 into v_begda.
concatenate '1231' into v_endda.
but system prompts "charlike-field" expected after "'0101'"
Can you please advice?

ALE data compare

ALE is set up between local and global box to send Employee data.
Users found out some discrepancies between the data and now we want to verify data between these 2 systems is in sync.
Any suggestion how to address above task

Thanks for suggestions...
Now challenge is...one system is global and another local.
Global is data source...so we will like to compare data from Global to local..
From Global data, we just want to compare local data...
Example: global is having World Wide employee data and we will like to compare only US employee data..
How to do that..

Is there any in-built function for date compare?

I need function which compare dates?

Hi,
You can simply use > , <,etc.,
Check this sample code.
data : d1 type RM06B-EEIND ,
       d2 type sy-datum.
d1 = sy-datum.
       CALL FUNCTION 'DATE_IN_FUTURE'
         EXPORTING
           anzahl_tage                   = '-7'

        IMPORTING
          EXPORT_DATUM_EXT_FORMAT       = d2
          EXPORT_DATUM_INT_FORMAT       = d2
if d1 < d2.
write 'h'.

Incoming Mins: 10.63          Outgoing Mins                   Incoming Mins
My requirement here is, I've want an alert on Percentage of Mins comparing its data with the previous day(Month for Tab 3 & 4) mins data. For now I've done this by creating a variable(with Relative Value Function) that stores the previous day or month's mins and stored the difference of these two data into another variable as Variation. I've put a percentage on the Variation variable and put a alert on it. It went well till here but, my requirement also has graphical alert on percentage. I tried adding the Variation variable and percentage and all available measures. But an error showed up with every try saying "Error in dataset values :#COMPUTATION"
Is there any other to do this report?
Note: I'm using WebI Rich Client v4.1 SP1

I tried using Franchise(Dim) and with that i've used Incoming Count, Incoming Mins, Variation separately. But nothing worked.

Date compare with system date

Given date time is in yyyyMMddHHmmss format, want to compare with system date time.
ie given date time is greater than zero then go inside if block otherwise else block.

I am using below code which always greater than zero. But I want to use compare to method to compare given date with system date and goto if or else condition:
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");
         String delaytimeFormat = sdf.format(new Date("10/10/2009"));
         System.out.println("delaytimeFormat: "+delaytimeFormat);
         long timeDiff = Long.parseLong(delaytimeFormat) - System.currentTimeMillis();
         System.out.println("timeDiff->"+timeDiff);
         String newCallbackUrl = null;
        if(timeDiff > 0){
             s = s+" new URL"+"test" ;
             System.out.println("if:->"+s);
        else{
             System.out.println("else");
        }

Webi Report Data compare between two columns

There is two different queries in Webi Report BI 4.1
Query 1 - Name_1 == 100 records
Query 2 - Name_2 == 75 records
On the report need to compare the data between Name_1 and Name_2.
Need report level flag as a second column
name_1 = name_2 = Y
name_1 <> name_2 = N
One the report there is only two columns Name_1 Flag(Y/N)
1. If statement is not working at all in this scenario
2. Merge dimension is not useful since I need to treat these columns separately on the report.

Hi Suri,
As the objects belong to two different queries, the comparison might not work as they are not merged and incompatible.
You can try creating a seperate query and can use subquery in it.
For example:
SELECT NAME_1 FROM QUERY_1
WHERE
NAME_1 NOT IN (SELECT NAME_1 FROM QUERY_2)
This will display the names which are not common.
Hope it will help.
Regards,
Yuvraj
