Get Differences between two databases

Hello there,
I need to check if there are differences between 2 databases, both on 10g. As I do not want to check all tables, triggers, procedures and so on manually I wonder whether there is a script where I just need to give the db_names for checking both databases?
best regards,
Jörn

Hi there,
first, I need to know structural differences like row datatypes, indexes or triggers. I don't need to know what exactly is different just which objects.
Second, I would also like content - differences between two tables, so the exact table data compared to each other. But this is not as important as the first one.
best regards
Jörn

Detecting differences between two databases

We've two big databases (20 Gb) on essbase 6.5 and System 9. We need to know if there are any differences between them. Is there a way to do that different from querying both databases with a lot of reports and comparing them?
Any suggestion will be helpful.
Thanks and regards,
Joaquin Castellano

You can compare two dbs with something I call a difference cube. For example, lets say you have two 5 dimensional databases that are very similar. Perhaps you made some changes in calcs and want to see the impact. Call the cubes Before and After . You could make a third copy and add a dimension. The members of the 6th dimension would be Before, After and Difference. Put a calc on Difference = After-Before. You can load the 5 dims worth of data from before to the before member and the same thing with after. You need to either use a rule with a header or you can use @XREF or partitioning. You can actually zoom and pivot through the resulting cube to identify differences.
There are some tricks to getting it right.
The first is to load the 5D data to the 6D cube. That's really not hard if you know how to use @XREF or parititioning or headers in a rule. I can explain this in detail or if you like I'll show you via a webex support session.
The second issue is size. If the first cube is 10gb then you will end up with 30gb for three versions. But you can moderate that by adding the 6th dimension to the Test cube and using dynamic XREFs.
Here is a link to a pdf that helps explain the process.
http://www.mtgny.com/Difference%20Cubes.pdf
If you send me your email address I'll send you some Maxl that will do the whole job for you with just a little tweaking for for your cube names etc.
Other things to look at include the outline chnage log file and the OLAP underground outline extractor to compare outlines.
Hope this helps. Please contact me if you need more info.

Most elegant way to get difference between two tables - not minus!!!

Hi,
Simplified example of what I am trying to achieve - I have two tables ORIGINAL and REVISED.
My desired result is to compare the two, such that; -
Where data exists in both tables I get the difference between the Budget column, and if there is no difference then I want no rows.
Where data exists in ORIGINAL but not in revised I want the inverse of the current value of the Budget column.
Where data exists in REVISED I want the value from REVISED.
I can see how I can do this, cf below, but is there a more elegant solution??
Data for table ORIGINAL
select '801040' entity, '2186' expense_type, 234000 budget
from dual
union all
select '801040' entity, '3001' expense_type, 1000 budget
from dual
union all
select '801040' entity, 'P132' expense_type, 34000 budget
from dual
union all
select '801040' entity, 'P135' expense_type, 43000 budget
from dualData for table REVISED
select '801040' entity, '2186' expense_type, 235000 budget
from dual
union all
select '801040' entity, 'P132' expense_type, 34000 budget
from dual
union all
select '801040' entity, 'P139' expense_type, 56000 budget
from dualDesired output
ENTITY EXPENSE_TYPE DIFFERENCE
801040 2186 1000
801040 3001 -1000
801040 P135 -43000
801040 P139 56000
5 rows selected.
Current code to achieve this, is there a better way??
select original.entity
,      original.expense_type
,       (nvl(revised.budget,0) - original.budget) as difference
from   original
,      revised
where original.entity = revised.entity(+)
and    original.expense_type = revised.expense_type(+)
and   (nvl(revised.budget,0) - original.budget) != 0
union all
select revised.entity
,       revised.expense_type
,       revised.budget as difference
from   revised
where not exists
(select 'x'
from   original
where original.entity = revised.entity
and    original.expense_type = revised.expense_type)
and    revised.budget != 0Many thanks for your input,
Robert.
Edited by: Robert Angel on 17-Jan-2012 03:31 to change not equals to != - thanks for heads up

Use full outer join:
with original as (
                  select '801040' entity, '2186' expense_type, 234000 budget from dual union all
                  select '801040' entity, '3001' expense_type, 1000 budget from dual union all
                  select '801040' entity, 'P132' expense_type, 34000 budget from dual union all
                  select '801040' entity, 'P135' expense_type, 43000 budget from dual
      revised as (
                  select '801040' entity, '2186' expense_type, 235000 budget from dual union all
                  select '801040' entity, 'P132' expense_type, 34000 budget from dual union all

How to get difference between two rows for a column field?

hi, all,
Could anyone show me what query statement is to get the difference betweem two rows for two column fields?
The tables and its records are like this:
id,      begin,      end
p1         21          30
p2          45          60
p3          120          150
I would like to have the query result like this
id,    diff
p1     15    --- which is 45 minus 30
p2     60    --- which is 120 minus 60
and so on...
thank you in advance.
Raffy

You can use the LAG function to access values from previous rows:
with q as (select 'p1' id, 21 v_start, 30 v_end from dual
union all
select 'p2', 45, 60 from dual
union all
select 'p3', 120, 150 from dual)
select id, v_start, v_end, v_start - lag (v_end, 1, 0)
over (order by id) v_diff from q
ID,V_START,V_END,V_DIFF
p1,21,30,21
p2,45,60,15
p3,120,150,60

Calculated columns to get difference between two dates with half day

Hi,
So there is the problem I'm using a calculated column to track the number of day when an employee make a vacation request. I'm already taking weekends of the case but now I would need to be able to ask for only a half day off.
How could I perform that without taking out my first requirement?
Just in case there is my current formula:
=IF(AND((WEEKDAY([EndDate],2))<(WEEKDAY([StartDate],2)),((WEEKDAY([StartDate],2))-(WEEKDAY([EndDate],2)))>1),(((DATEDIF([StartDate],[EndDate],"D")+1))-(FLOOR((DATEDIF([StartDate],[EndDate],"D")+1)/7,1)*2)-2),
Thanks for your answers :)

Hi amber,
you can simple calculate.
try this:
DATA: date1 like sy-datum,
date2 like sy-datum.
data I type i.
date1 = '20070301'.
date2 = '20070228'.
i = date1 - date2.
write: / date1, date2, i.
date1 = sy-datum.
date2 = sy-datum - 30.
i = date1 - date2.
write: / date1, date2, i.

i want to get difference between two date into text Item :P36_C in On Change java script.
i have two Date Item :P36_A and :P36_B .i have extract these date value from table then difference comes into Text Field :P36_C.
Now i want if i change Date into Item :P36_A or Item :P36_B then Defference between two date Should Come into Item :P36_C .
So i have use Java Script Code to do this
<script>
function diffdat(){
    function getVal(item){
   if($x(item).value != "")
     return parseFloat($x(item).value);
   else
     return 0;
    $x('P36_C').value =
getval((TO_DATE('P36_B', 'DD-MON-YYYY'))-
getval(TO_DATE('P36_A', 'DD-MON-YYYY')))+1;
</script>
i have put this into Item HTML Form Element Attributes
onChange="javascript:diffdat();"it's not woring .
How to work that Code with dates.
Thanks

You can always create your own difference function based on your own criteria. You can modify this to suit your needs.
CREATE OR REPLACE FUNCTION CALC_OFFICE_DAYS(date1 DATE, date2 DATE)
RETURN NUMBER
IS
v_begin_date DATE := date1;
v_end_date DATE := date2;
v_office_start_time VARCHAR2(10) := '09:30 AM';
v_office_end_time VARCHAR2(10) := '06:30 PM';
v_comp_begin_time DATE;
v_comp_end_time DATE;
v_days PLS_INTEGER := 0;
v_hrs NUMBER := 0;
v_ttltm NUMBER;
BEGIN
select trunc(v_end_date) - trunc(v_begin_date)
into v_days
from dual;
select to_date(to_char(sysdate,'DD-MM-YYYY')||' '||to_char(v_begin_date,'HH24:MI'),'DD-MM-YYYY HH24:MI')
into v_comp_begin_time
from dual;
select to_date(to_char(sysdate,'DD-MM-YYYY')||' '||to_char(v_end_date,'HH24:MI'),'DD-MM-YYYY HH24:MI')
into v_comp_end_time
from dual;
select (v_comp_end_time - v_comp_begin_time)/24 into v_hrs from dual;
IF v_hrs > 4 then
v_ttltm := v_days + .5;
ELSE
v_ttltm := v_days;
END IF;
return v_ttltm;
END;
As has been noted, this question is best posted on the PL/SQL forum.

How to get the difference between two columns in a column group

Hi All,
My first time here and really new to programming. I would like to get the difference between 2 columns that are inside
a column group.
Here is my sample table below: The Column Group is PeriodNumber and can only choose 2. like 1 and 2.. I would like to have a third row which will simply calculate the difference between the amounts in PeriodNumber 1 and 2.
PeriodNumber
Account 1 2
1) Cash 10,000 15,000
2) Receivables 12,000 11,500
3) Equipment 5,000 5,500
Total Assets 27,000 32,000

Hi yabgestopa,
From your description, you want to get the difference between two columns in a column group. After testing it in my environment, we can use custom code to achieve your requirement. For more details, you can refer to the following steps:
Copy the custom code below and paste it to your report. (Right-click report>Report Properties>Code)
Dim Shared Num1 As Integer
Dim shared Num2 As Integer
Public Function GetAmount(Amount as Integer, Type as String)
If Type = "1" Then
Num1=Amount
Else
Num2=Amount
End If
Return Amount
End Function
Public Function GetDif()
Return Num1-Num2
End function
Right-click the second column to insert a third column with Outside Group-Right.
Then use the expressions below in the matrix.
=Code.GetAmount(Fields!Amount.Value,Fields!PeriodNumber.Value)
=code.GetAmount(Sum(Fields!Amount.Value),Fields!PeriodNumber.Value)
=Code.GetDif()
The report looks like below.
If you have any questions, please feel free to ask.
Thanks,

How to get percentage difference between two matrices?

You probably converted it to a 2D array (A matrix in LabVIEW has a special meaning).
"Binary" is not very well defined (unless you are looking for the number of bits that are different). What is the datatype? Was it a color image or a greyscale image? Are both arrays the same size?
How do you define "percentage difference"? Which one of the two is the 100% reference?
Do you want a new 2D array where each element is the difference of the second array compared to the first (or vice versa), expressed in percentages?
Do you want to know what percentage of array elements are different between the two arrays?
Do you want to know the average difference between all array elements?
All possible interpretations can be easily solved with very little code, but you need to explain in more detail what you actually want?
Here is a simple solution for case #2, for example (assuming the array have the same size, and we only want a rought estimate, rounded down to the nearest integer percent):

thanks ! cary ,
I have a list contained some BufferedImages gotten from AWT component,and then these images
will be transfered to client and displayed in Internet explore ,actually there are only some difference
between two continuous BufferedImages,i don't want to transfer the WHOLE image to client,SO i
want to handler every image before sending to client , at last, the different part will only be sent to client.
All these ideas will be contained this method:
* Compare the specified two BufferedImages and return the different part between them.
* @param ref the specified first image
* @param gen the specified sencond image
* @return the different part between the specified two images.

Function Module to get the difference between two times.

Hi All,
I want to know if there is any function module that gives me the difference between two specified times.
For Ex: Time 1: 12/01/2007 00:01 A.M
            Time 2: Time 1 - 180 Seconds. This changes the time, also may even change the Date. (As in above situation, the Time 2 will be 11/30/2007 11:58 P.M)
Could some one please suggest if there is any function module for this case.
Thanks in Advance.
