How to compare two database objects?

Hi,
I need to compare two objects with embedded objects/collections in it to tell exact difference between the two.
e.g.,
create type t1 as object (name varchar2(10), age number);
create type t2 as table of t1;
create type t3 as object (user t1, family t2);
... and so on.. this type hirarechy is big in my case..
I want a procedure/function which can tell me what and where is the difference.
PROCEDURE (obj1 T1 , obj2 T1) IS
BEGIN
END;
e.g., t1.name = 'John' and t2.name = 'Mich' then it should return t1.name etc..
Is it possible?
Thanks

Why a new thread?
how to read objects/collections dynamically?

How to compare two database on different servers

hi,
I want to compare two database on different servers in oracle.first i want to ckechk thier structures and then data.i m using oracle 10.2.0.plz help me out
Thanks in advance

In terms of structures, there are various tools out there that can do this, such as TOAD which can do a database compare.
In terms of data comparisons, that will depend on what sort of results you are expecting to see. I'm sure some tools will do it for you, but it can be just as easy to write your own comparison using a database link from one database to the other.

How to compare two databases, without dblink?

Hi all,
I need to compare two differents databases, but I can't create a database link, and for make this task worse, I need to do this using a shell script, because it will run directly in the server.
Anybody can help me?

Hi Justin,
I made the script, and it was working pretty well, but when I was running in the production environment, I get the information that I need to connect with one user and get the ddl to another user, ok, I change the script but now I'm receving the error ORA-31603.
SQL> show user
User is "tstsge3"
SQL> select dbms_metadata.get_ddl('TABLE','INTBD_INS_ACIONAMENTO','TSTINTBD3') ddl from dual;

I took a look on the internet and metalink, and saw some notes about grant SELECT_CATALOG_ROLE to the connect user, but I can't do this in my customer.

How to compare two date Objects

Hi,
I have two Calendar Objects, one is coming from client and one is my server time, I need to evaluate that incoming time with server time so that if it is sent before an hour back then i should not do anything on that request Object. I have converted the incoming String into Calendar Object and how can i evaluate these two Calendar Objects including their hours and minutes.
Thanks in advance

bajjurireddy, ignore Mobiquity's post. It contains no useful information and will only serve to confuse and frustrate you.

Also make sure that the two date objects are in the same date format..
public static String DateToDateString(java.util.Date d, String dateFormat)

How to compare two Objects !!!!

Hi All,
I know that this question has been asked 100 times till now. But trust me I have checked all of them but couldn`t find answer. Here is my question:
I have an objecs. In that object I am setting (Id,Name,DOJ). Now I want to check whether the object I am trying to save in database already exists or not. If exists then I need to check whether all the setters are same for the two objects. Now can anyone tell me ,how to compare two objects directly without comparing the setters individually.
Thanks in advance.

pavan13 wrote:
That is pretty good idea. However I have a query. Does that code actually compare all the setters in a two beans. I don`t want to check each setter seperately.Well, it's pretty meaningless to talk about "comparing setters", setters are methods, they don't have values to compare. Because equals is inside the class, you can simply compare the fields that get set by the setters. "Properties" is probably a better name.
In principal you could write something that tried to find all relevant fields and compare them, using reflection or bean info stuff. The resulting code would be about 50 times longer and take about 50 times longer to run. It's hardly asking a lot to put three comparisons between && operators.
Remember, though, not to compare string fields with ==, you should call .equals on the string fields.
p.s. don't let the bean terminology confuse you. Beans are just ordinary objects which follow a few rules. Personally I wish the term had never been coined.

??how to compare two resultsets??

hi all!
i need to find out whether two resultsets contain the same data.
the only way i know how to do it in java is to put them into a while loop and fetch the contents first and then compare the contents.
but is there an easier way to compare resultsets?
does anyone know how to compare two resultsets without extracting the data?
the code example here executes two identical queries on an oracle database, compare and print the resultsets.
public ResultSet getResultset(String query)
ResultSet rs=null;
try { rs=Stmt.executeQuery(query); }
catch(Exception e) { e.printStackTrace(); }
return rs;
public static void main(String[] args) {
ResultSet r1=null;
ResultSet r2=null;
try {
database db = new ddatabase();
r1=db.getResultset("Select 'name' from person");
r2=db.getResultset("Select 'name' from person");
if (r1 == r2) {
System.out.println("ok");
System.out.print(r1);
System.out.println();
System.out.print(r2);
else {
System.out.println("not ok");
System.out.print(r1);
System.out.println();
System.out.print(r2);
jdbc.cleanup();
catch(Exception e) {e.printStackTrace();}
and here is the output:
F:\java rs_compare
not ok
oracle.jdbc.driver.OracleResultSetImpl@4413ee
oracle.jdbc.driver.OracleResultSetImpl@786e64
as you can see the resultsets are different though the data they contain have to be the same.
so the 'if(resultset#1 == resultset#2)' does not work.
thanks for any help
best regards
5ithl0rd

Don't cross-post.
I'll bet ResultSet implementations don't override equals() to provide "deep equals" behavior, in which case it'll be no different than using "==".
It's a bad idea to compare two ResultSets this way. You'll have to load both into objects or data structures and compare those in a "deep" way.
Besides, the ONLY way two ResultSets could be different, given the same query, would be if there were multiple clients that could write to the table between queries and change the underlying data. If your two queries are sufficiently isolated, I'd say that the same query will return the same ResultSet.

How to compare two strings whether both are equal while ignoring the difference in special characters (example: & vs & and many others)?

I attempted to compare two strings whether they are equal or not. They should return true if both are equal.
One string is based on Taxonomy's Term (i.e. Term.Name) whereas other string is based on String object.
The problem is that both strings which seem equal return false instead of true. Both string values have different special characters though their special characters are ＆ and &
Snapshot of different design & same symbols:
Is it due to different culture or language?
How to compare two strings whether both are equal while ignoring the difference in special characters (＆ vs &)?

Hi Jerioon,
If you have a list of possible ambiguous characters the job is going to be easy and if (＆ vs &) are the only charracters in concern awesome.
You can use the below solution.
Before comparing pass the variables through a replace function to standarize the char set.
$Var = Replace($Var,"＆","&")
This is going to make sure you don't end up with ambiguous characters failing the comparison and all the char are "&" in this case.
Similar technique is used to ignore Character Cases 'a' vs. 'A'

How to compare two stored procedure?
What is the command to compare the stored procedure?

select line, text
from user_source
where name='....'
minus
select line, text
from user_source
where name='....'
should do nicely.
Or: get the procedure text to a file using dbms_metadata.get_ddl (9i and higher) and run diff (Unix) or fc (Windhoze) on it.
You are a bit scarce on details.
Better still: implement source control.

How to compare two different environments

Can any please tell me how to compare two environments like DEVL to TEST?
I know how to compare a project(like DEVL to TEST) but i want to see all the changes in all the objects between two different environments.
Please help me.
Thank you.

That is really a good piece of information.
Does it really matter where we are comparing from?
i will explain,let us say we have DEV and TST environment.
let us say both has same project name and the same number of objects but inside the object they may be different(like number of fields in the same record in both environments).
Now we want to have a compare report between those environments.
We can do in two different ways, right?
(1. source DEV, Target TST)
(2. source TST, Target DEV)
will the result get changed in both the cases?
(except like following)
(first case souce target)
( absent *changed)
(second case would be like following)
( souce target)
( *changed absent)
(but i gess the number of rows in both the cases does not get changed)
let me know if you can not understand the question. sorry about the confusing explanation

Hi Tina,
You can use a trnasactions like SCMP, SADJ or SCU0 - all tools to do comparison of customizing objects across clients/systems using RFC.
Details of these tools, their usage and functionalities are available in the Help Portal -

Compare two Java Objects without Comparable / Comparator

Hi Friends,
I would like to compare two java objects (lots o attributes) without using Comparable / Comparator.
Any suggestion/sample code would be helpful.
Thanks,
Sachin

I suppose you could design another feature to compare Objects... but that would involve a design process, so asking for sample code is definitely premature. And as EJP says, what would be the point?
At least that's what I would answer if this was one of those stupid interview questions.
