Compare two tables and log the difference

Hi,
I want to compare two tables and log the difference in new table with the fields as (old value,new value, column name). The column name should be the changes value column

Can you show an example?
SELECT Foo.*, Bar.*
FROM Foo
FULL OUTER JOIN
Bar
ON Foo.c1 = Bar.c1
AND Foo.c2 = Bar.c2
AND Foo.cn = Bar.cn
WHERE Foo.key IS NULL
OR Bar.key IS NULL;

Script to compare 2 tables and retrieve the differences in records data

Dear All,
please I need a script to compare two oracle database tables and retrieves the differences in data records between the two tables.
I have tried this one :
-- all rows that are in T1 but not in T2
(select * from T1 minus select * from T2)
union all
-- all rows that are in T2 but not in T1
(select * from T2 minus select * from T1);
But it generates the following error:
ORA-01789: query block has incorrect number of result columns
Thank you for your cooperation , please it is urgent

ok I used this statement with dblink, the problem is that i cannot use PL/SQL developer since it is a process repeated for 300 tables , that why i am trying to automate it:
-- all rows that are in T1 but not in T2
(select * from schema.T1minus select * from T2@dblink_name)
union all
-- all rows that are in T2 but not in T1
(select * from T2@dblink_name minus select * from schema.T1);
I created the db link on a database A and when i run the statement
(select * from schema.T1minus select * from T2@dblink_name)
on the database B i get the error ORA-02019: CONNECTION DESCRIPTION FOR REMOTE DATABASE NOT FOUND.
DOes anybody have an idea please

How to compare two images and display the difference on Front Panel

The missing thing. You have to keep in mind that what you see is not the same as the camera sees.
So when using IMAQ Substract it gives you the difference of the value of every single pixel!
In order to find the mouse as only difference you have to manage that every other pixel value stays the same, e.g. with a proper lightening.
At the other hand you can combine different filters or alogorithms to get the object, e.g. if the object is darker or brighter then everything else in the image you could use a threshold and then use morphologic operations to get the objects size and position.

Comparing two tables and picking the records

I have two tables A and B. I have to compare a column ID in both table A and table B A.ID=B.ID And based on the above comparison if the match is found I need to pick the records from table A and if no match then need to pick the records from table B My problem is if I join then I will have table A and table B as one record and will be difficult to separate out. Please let me know how this can be acheived. Thnx.

I know this email is confusing and really hard to understand...perhaps now you will know how i've been feeling--lost and confused with all the mis-information, with a hit and miss phone, and out of time with all the 1 1/2 hr to 2 hrs EACH wasted on this issue.
On top of all this, I can't even find out how to file a complaint with anyone higher up than Customer Service.
I hate to tell you this, but you didn't write an email. You wrote a discussion post on the Verizon Wireless Community forum which is a public peer to peer forum. Unfortunately since you didn't mark your post as a question, the VZW reps that roam this community won't ever see your post. Before you re-post it, don't. Duplicate posts get removed from the community.
I see there were several missteps both by the reps and yourself in your post. First you should have insisted on returning the phone within the 14 day return policy period. Second which Samsung Galaxy mini model did you purchase? The S3 mini or the S4 mini? Did you do any research prior to deciding on this device. The reps at that time deflected the easiest course of action, by trying to get you to replace the phone under insurance instead of returning the phone. The Early Edge payment option requires the current phone on the line using the early Edge must be returned to Verizon Wireless. Did you once considered going to a third party site like Swappa to purchase a gently used device for your daughter?

Comparing sum from two tables and correct by difference of sum in second t,

Hello Guys,
I have a very tricky task that I cant get my head around.
The sample data looks like that:
Master Table
Claim------Booking--------Debit--------Credit------------MasterAmout
1------------1----------------D---------------------------------15.3
1------------2----------------D---------------------------------480.6
1------------3------------------------------C-------------------496.8
------------------------------------------- 0.9
Slave Table
Claim-----Booking-----Debit------------Credit----------SlaveAmout------- SlaveCorrection
1------------1------------D------------------------------------15.3---------------14.5
1------------2------------D------------------------------------480.6-------------480.6
1------------3-----------------------------C-------------------496---------------496
-------------------------------------------0.1--------------------------------------0.9
The booking have a total amout of 0.1 but has to be corrected to 0.9 because the master table has 0.9.
Booking 1 requires a correction so the slave table also has a total of 0.9 (business rule is, corrections only on first booking). so we have
to change the amount from 15.3 to 14.5. I plan my SQL like that:
1. Sum bookings from both tables for each Claim. Compare the two for each individual claim.
2. If the Master sum of the amount shows a difference between the master and slave table
     2.1 select top 1 booking from slave table for the specific claim and increase/decrease by the difference of those two amounts.
Does that make sense?

Hello
It would be really helpful if you could a) format your posting properly using the {noformat}{noformat} tags around your data and b) provide create table/ insert statements.
Anyway, from what you described -
Booking 1 requires a correction so the slave table also has a total of 0.9 (business rule is, corrections only on first booking). so we haveto change the amount from 15.3 to 14.5
You could achieve this with an analytic function and an outer join...WITH Master_Table AS
SELECT 1 Claim, 1 booking, 'D' debit,NULL credit,15.3 masteramount from dual union all
SELECT 1,2,'D',NUll,480.6 from dual union all
SELECT 1,3,NULL,'C',496.8 from dual
Slave_Table AS
( SELECT 1 claim, 1 booking, 'D' debit, null credit, 15.3 slaveamount,14.5 slavecorrection from dual union all
SELECT 1,2,'D',NULL,480.6,480.6 from dual union all
SELECT 1,3,null,'C',496,496 from dual
SELECT
m.claim,
m.booking,
m.debit,
m.credit,
NVL(s.slavecorrection,m.masteramount) amount
FROM
master_table m
LEFT OUTER JOIN
( SELECT
claim,
booking,
slaveamount,
slavecorrection,
ROW_NUMBER() OVER(PARTITION BY claim ORDER BY booking) rn
FROM
slave_table s
) s
ON
( s.claim = m.claim
AND
m.booking = s.booking
AND
s.rn = 1
CLAIM BOOKING D C AMOUNT
1 1 D 14.5
1 2 D 480.6
1 3 C 496.8

Compare 2 schemas and get the difference with .sql file.

Hi,
I am using ORACLE DATABASE 11g R2 and ORACLE Linux 5.
I want to perform a very lengthy process and want to make it automated.
I am having a software named as SVN. In which all the developers keep their updated scripts.
We have 2 schema's one is used for developement and when all the development seems good we implement the scripts on the final schema which is used by testing people also.
Now every day we need to check the modifications in the development schema, that we do by observing the updated scripts in the SVN software. Now we get the scripts which are modified.
We will fire this scripts to a sample schema then we will compare the objects in this schema and the same objects in our final schema. If the objects in sample schema is different than the final schema it should give me the
script to create the same type object in the final schema.
Below is a proper example to explain :-
Developement Schema :- 'DEV'
SVN Script Schema :- 'SVNscript'
Main Schema :- 'MAIN'
1) On Monday developers modified/added 4 tables in the development schema names 'DEV' after working for a day they found that the changes are necessary and so checked-in in the SVN software.
2) On tuesday morning we found 4 scripts which has been modified/added in the SVN.
The Scripts were as follows :-
1St table :- An extra column was added.
2nd table :- An index was created on it.
3rd table :- 2 Columns were dropped from it.
4th table :- A new table is added in the schema.
Now taking these 4 scripts i am going to execute it in a sample schema named :- SVNscript
SVNscript schema will have now 4 tables with proper properties(columns,indexes,...). Now this is the final table structure as we want in our 'MAIN' schema .
Coming to MAIN schema which is our most important schema and all the development work is finally posted here.Considering MAIN schema is having around 1000 tables,500 function/procedure/package and many more DB objects.
I want to compare(one way compare) from SVNscript schema --> MAIN schema :- That the objects present in the SVNscripts schema is same or not in the MAIN schema. If its not same then this code should generate a .sql script for me which i should be able to fire on the MAIN schema.
The output .sql scripts should be something like this :-
1st Table :- Alter table add...
2nd Table :- Create index on table...
3rd Table :- Alter table drop...
4th table :- Create table tablename...
I found a link while trying this but it is not the perfect fit to my requirement
http://www.dbspecialists.com/files/scripts/compare_schemas.sql
Please let me know the best code to compare 2 schemas and get a .sql file as output of the difference.
Thanks in advance.

Yes I followed the tutorial properly this time. Still i have a few queries :-
1) This is returning me the 'ALTER TABLE...' statement but how to make it more efficient to return all the DDL dependent on the table, Like index,trigger,view...
2) I want to compare objects in a different schema on a different db. I have created an DBLINK but how to use it ... can i use it like
DBMS_METADATA.OPEN('TABLE'," Network_link_name " );Can you please give me some clear about it.
3) I created a table 'TAB1' with which i want to compare a 'TAB1' in other schema.I was not getting how to compare on remote dblink so,I created the same table with the following code in the same schema
CREATE TABLE TAB1_OLD as select * from TAB1@DBLINK where 1=2;Now when i fire the below query to get the alter difference I get the following error :-
SQL> SELECT get_table_alterddl('TAB1','TAB1_old') FROM dual;
SELECT get_table_alterddl('TAB1','TAB1_old') FROM dual
ORA-31603: object "TAB1_old" of type TABLE not found in schema "SVNCHECK"
ORA-06512: at "SYS.DBMS_METADATA", line 5225
ORA-06512: at "SYS.DBMS_METADATA", line 5189
ORA-06512: at "SVNCHECK.GET_TABLE_SXML", line 17
ORA-06512: at "SVNCHECK.COMPARE_TABLE_SXML", line 12
ORA-06512: at "SVNCHECK.GET_TABLE_ALTERXML", line 11
ORA-06512: at "SVNCHECK.GET_TABLE_ALTERDDL", line 11
Can you please guide me why i am getting this error?
I have made sure that TAB1_OLD table has been created and the entries are also present in the data dictionary tables.
SQL> select * from tab1_old;
EMPNO ENAME MGR DEPTNO
----- -------------------- ----- ------The only difference is that this table was created with CREATE TABLE AS SELECT statement ....
Thanks.

How to join two tables and get the supply delivery date next to order?

So there are two tables. One has customer's order no, ordered date, order quantity, available quantity and code of article-
The other table comes form supply side where we have supply order no, article number, ordered qty, and delivery date.
We keep stock so this can not be MOT (made to order) system.
What i need is correct date of arrival to appear next to cusotmers spoecirfic order. The older cusotmers order get's the parts first, second oldest order is next in line etc.
here is any example
customer's order
ref order
art. code
ordered qty
available qty

There is actually a 3rd "table" and that sort of connects the two and that is stock on hand per art. code.
The main issue is that stock is assigned to purchase orders only when it actually arrives in the warehouse.
A human can easilly connect the dates of when the stock will arrive and quantities with correct customer's order. In this case the firts order will get 50 pcs in August while 10 pcs will remain on backorders. The missing 10 pcs Will arrive in October. The second order will get 10 pcs in october and 3 will remain on backorders with no delivery date. While the third customer orders does not have a delivery date.
So how to make the SAP do this calculations and display the arrival date next to date of customer's order?

I checked the instructions as i do not have access to this part. It seem this is a query. We had issues with queries in the past as not all codes from orders would appear in them. They never found the reason why that is happening.
However, I think the main issue is that the information here is not connected and is separately provided for supply and for sales. So i doubt it can be connected in this query.
edit: as you can see the only connection is stock on hand.
and total number of various items we have is close to 100.000 of various article codes.

Find datetime difference between two fields and add the difference to the current datetime.

Hey,
You can try this
SELECT DATEDIFF(Day, D1, D2) as Date_Diff from Table_3
Replace day with
other units you want to get the difference in, like second, minute etc.

Join two tables to query the difference of both

Hi,
I think my problem is not the hardest, but I don't find a solution.
- i have two tables: t_old, t_new
- both have the same attribute (item_nr)
- t_new exists of some rows from t_old and some new rows
I want to query only the new rows from t_new, that aren't in the table t_old.
Who can help me please..???
Regards,
Steffen

wrong forum, sorry, but i got it in another forum:
select * from t_new n
where not exists
(select 1 from t_old o
where n.item_nbr = o.item_nbr)
(THX to Keith Jamieson)
or
select * from t_new
minus
select * from t_old
(THX to Boneist)

Need to compare two fields and populate the other fields.

Hi All,
I have scenario like this.
DATA: text1(150) type C
VALUE 'Step: SHORT DUMP; Scenario: PRE; Date :09.07.2007. Time :13:08:33.'.
DATA: text2(150) TYPE C
      VALUE 'Step: &; Scenario: &; &',
DATA: text_A(150) TYPE C,
          text_B(150) TYPE C,
           text_C(150) TYPE C.
Now I need to compare text1 and text2 and populate text_A, text_B and text_C as follows.
text_A = SHORT DUMP
text_B = PRE
text_C = Date :09.07.2007. Time :13:08:33.
Basically I need to fill text_A, text_A and text_A with the values in text1 which are replaced by '&'.
Can anyone suggest me a code snippet to do it?
Thanks in advance.
Regards
Ankit

Sorry for slow response - I'm in a different timezone I think... Well it's not a short algorithm, but you could try something like the following (there's probably a sweeter algorithm, but this is what occured to me overnight)... I realise that it's not foolproof as you could have words substituted in for the "&" that also appear in the original message text and that would skew the results...

Stored Procedure to compare two tables data

Hello,
I want to have a Stored Procedure which will compare data (only a single column) of two tables and delete the row which is not present in the second table.
For eg.,
I have got 2 tables called Table1 and Table2, which have the same column called ID(PK).
The data in Table1 is 1,2,3 and data in Table2 is 1,3. When the stored procedure runs, it has to compare the ID column in Table1 to ID column in Table2 and since '2' is not there in Table2, I want to delete this row from Table1.
Thanks in advance.

How to compare two tables in SSIS?

I am creating an SSIS package that will compare two tables and then insert data in another table.
Which tool shall I use for that? I tried to use "Conditional Split" but it looks like it only takes one table as input and not two.
These are my tables:
TABLE1
ID
Status
TABLE2
ID
Status
TABLE3
ID
STatus
I want to compare STATUS field in both tables. If Status in TABLE1 is "Pending" and in TABLE2 is "Open" then insert this record in TABLE3.

You can use MERGE command , Sorry cannot test it right now.
MERGE INTO tbl3
USING (SELECT tbl2.ID, tbl2.status,tbl1.status as st1 FROM tbl1 JOIN tbl2 ON tbl1.ID=tbl2.ID) AS t ON T.ID=tbl3.ID
AND t.status='OPEN' AND t.st1='pending'
WHEN NOT MATCHED
INSERT (status) VALUES (t.status)
