Create ViewCriteria comparing two columns from same table

Does anyone know how I can create a ViewCriteria where clause that compares two columns from the same table?
For example if I had two integer columns (MINSAL and MAXSAL) and wanted to see if they are equal. I would normally do the following SQL below.
SELECT * FROM EMPL
WHERE MINSAL = MAXSAL

It works, but it is not ideal.
Setup a Transient column that performs a groovy evaluation of MINSAL=MAXSAL and then my ViewCriteria evaluates the column to true and I set Query Execution Mode to Both.

Problem creating a datablock with columns from 2 tables...

Hello guys, i have a problem in creating a datablock with columns from 2 different tables. I try to create the datalock manually and in the Query Data Source Type Property i choose FROM clause query, and in the query data source name property i type my sql statement with the columns i want to display.After that i place the items that the datablock will contain , manually from the painter. However , when i run the application, the datablock doesn't display the items from the database. Am i doing something wrong?
Thanx in advance,
Regards,
Bill.

Never mind Peter, I found the error. I forgot to make execute_query for the datablock, so this was the reason why the items weren't displayed to me.
Thanx anyway a lot for your advices and your time you spent !

Compare two rows in same table

Hi,
I want to compare two rows (some columns) in the same table, and if the data in the data columns is different, I want to pick the latest one. The table is date tracked. For instance I have an address table with different addresses for an employee with effective date. I want to be able to pick the latest row if the postal code is different for the 2 rows. Is this possible in sql. I can do this in Pl/sql, but dont want to use it. Eg
address_id, postal_code, person_id,last_update_date
123, pn123,1,12-JAN-01
124,pu124,1,13-JAN-01
I want to be able to retrieve just the second line.
Any help is appreciated

Welcome to the forum!
Whenever you post please provide your 4 digit Oracle version (result of SELECT * FROM V$VERSION).
>

Your question is a little confusing because you are using terms like 'date tracked' and 'effective date' without explaining exactly what your definitions of those terms is.
Why do you want the latest record ONLY if the postal code is different? What if the address is different? Then which record do you want?
Why not just take the record for each person/company that has the latest date? If the data is the same then it doesn't which record you get so the one with the latest date will do. And if the data is different taking the one with the latest date gives you the latest data.
The classic definition of effective date is 'the date the information becomes effective'. Information with a given effective date is NOT in effect before that date and is SUPERCEDED when data is entered with a later effective date if the actual date is later than or equal to the effective date. Using your data
>
123, pn123,1,12-JAN-01
124,pu124,1,13-JAN-01
>
The first record IS NOT effective for dates prior to 12-JAN-01. In fact for a query looking for data prior to that date there isn't any data.
The first record is also NOT effective for dates on or after 13-JAN-01. Only the second record is effective.
If you added a record for 14-JAN-01 this record would not be effective until on or after that date (i.e. not for another 4 1/2 months).
So for the classic definition of effective date the query needs to provide the AS OF date to use to obtain the data. If, as in your system, you are not allowed to create records with dates in the future and you just want the latest record then you can just select the record with the MAX(myDate) value for the given person_id, address_id or whatever your key values are.

Satyaki De,
Java is involving because an Outsourcing new project. The outsourcing company is developing the new application using JSF which invoke an interface java method [depending of the operation: select, update, insert] and them invoke the PLSQL API to precess tha operation.
In the case I already wrote here, the issue is this:
The user search for a specific data using the interface. The java method send a request for these operation through the API. the PLSQL process the request and return a beam, with all the column the user look for.
The user see the information in the application windows. Assuming the user wants to change some data, he modify just one field [lets say telephone number] and press the update button. The application process the request using a different method, which invoke a different function within the PLSQL API.
Once the information is returning to the API, I must know if at least one field change its value. So I was thinking to get the beam with the data before it was changed and compare it with the beam with the changing data.
If current_beam = new_beam
then
update
else
no change to process
end if;
Any idea.

Question about suming two columns from different tables in Subquery?

Hello everyone,
I have a subquery that works great for getting the total SUM of a Billing table, but I also need to add to that SUM the total surcharges or additional charges from a separate table. I tried this by doing something like so:
(SELECT SUM(SUM(Amount) FROM Billing WHERE Billing.JobID = Jobs.ID AND Billing.BillingType = 'Invoice' AND Billing.InvoiceCanceled = 'No', SUM(Payment) FROM Payments WHERE Payments.JobID = Jobs.ID AND Payments.Type = 'Bill')) as [Amount],
But it doesn't work as there is an incorrect syntax near 'FROM'. I'm assuming this is because of the two FROM's in the Subquery? But I am not sure how else I would be able to do this then?
Any help would be greatly appreciated. I just noticed this bug and am hoping to get a fix out as quickly as possible.
Thanks Again,

Hi, sorry for taking so long to get back to this post.
I tried this example like so:
(SELECT SUM(A1) AS Total1, SUM(A2) AS Total2
FROM
(SELECT
(SELECT SUM(Amount) FROM Billing WHERE Billing.JobID = Jobs.ID AND Billing.BillingType = 'Invoice' AND Billing.InvoiceCanceled = 'No') AS A1,
(SELECT SUM(Payment) FROM Payments WHERE Payments.JobID = Jobs.ID AND Payments.Type = 'Bill') AS A2),
However, get an error that an Incorrect Syntax exists near the ','. I remove the comma (Which I think should be there), and I get an error that an Incorrect Syntax exists near the '.'...
I also tried doing it like this (Based on other suggestions I've found online:
(SELECT SUM(SELECT SUM(Amount) FROM Billing WHERE Billing.JobID = Jobs.ID AND Billing.BillingType = 'Invoice' AND Billing.InvoiceCanceled = 'No') as [Amount],
(SELECT SUM(Payment) FROM Payments WHERE Payments.JobID = Jobs.ID AND Payments.Type = 'Bill') as [Additional]),
And I get an error that an Incorrect Syntax exists near 'SELECT'...
I also tried doing something like this with the SQL I already had...
(SELECT SUM(Amount) FROM Billing WHERE Billing.JobID = Jobs.ID AND Billing.BillingType = 'Invoice' AND Billing.InvoiceCanceled = 'No') as [BilledAmount],
(SELECT SUM(Payment) FROM Payments WHERE Payments.JobID = Jobs.ID AND Payments.Type = 'Bill') as [Additional],
SUM(BilledAmount + Additional) AS [TotalBilled],
But I get an error that the alias' are Invalid Column Names... I have used Alias' before so I'm not sure why this would be an issue here...
As you can see, I've been trying to figure this issue out, but haven't had much luck... :(

I want to come those 2 queries into a single query, such that it gives both outputs as above. Let me know if you need any other information. thanks.

Compare two records column by column in same table

Hi All,
I have an address table with ID as the PK but there can be more than one ID. I need to take the latest address record and first see if that same ID has a previous address record and if so, compare each column to see if the data has changed. I only need to compare the latest record with the next latest record.
I cannot figure this out at all. I can of course use the MAX function to get the latest address records but do not know how I can pull the next latest address record that matches the ID and compare each column.
Sample table:
ID street city state zip effective_date
1 123 main chicago IL 60111 3-7-2012
2 34 N 13th new york NY 18374 3-7-2012
3 15 N main Dallas TX 47389 3-7-2012
1 89 N main chicago IL 60111 1-5-2012
1 16 East St columbus OH 47382 12-10-2011
2 34 N 13th new york NY 18374 10-7-2011
2 15 S Elm new york NY 18374 09-1-2011
3 15 N main Dallas TX 47389 10-4-2011
SO...in the table above using today as the latest record date, based of my criteria I would only want to pull record ID 1 and 2 since the next most recent record for those IDs have had at least one of their address data change. ID 3 has exactly the same address data so I would not consider that in my criteria.
Can i do this with SQL only or will i need to create a procedure or function?
Any help is appreciated

ORDER BY id
,            effective_date
;This will show the most recent 2 rows for each id that has 2 (or more) rows.
You can modify it to only include ids where there was some change in street, city, state or zip between those 2 rows.

OR       state_cnt     > 1

ORDER BY id
,            effective_date
;This assumes that street, city, state and zip are all VARCHAR2s. If any of those columns is NULL on one row, and not NULL on the other row for that ID, that counts as a difference.

How to compare two fields from the same table in the select statement

Hi, friends
I try to compare tow fields from the same table, but no result,
For example, this
data: cptotchek tyep i.
select count(*) into cptotchek
from aufk where erdat = aufk-idat2 .
The result is cptotchek = 0, but there are the records in aufk , where, aufk-erdat = aufk-idat2.
Please, help me, i don't use the loop statement for optimize my program.
Regards

Hi ,
       it will not return any value   when you are using   column of same table
       such as Date Field   , Because while Using Aggregate Function it will not check with self column
.      For that you have to take data in one internal table and then you can work on it .
     And if you are worried about Performance it will not affect , untill you are selecting only required data .
you can try this way .
data: cptotchek type i.
types : begin of w_aufk.
        include structure aufk .
      types : end of w_aufk .
data : it_aufk type standard table of w_aufk with header line .
select * into corresponding fields of table it_aufk
from aufk .
loop at it_aufk .
if it_aufk-erdat = it_aufk-idat2 .
write : / it_aufk-erdat , it_aufk-idat2 .
else .
delete it_aufk .
endif .
endloop.

Need to compare values in two columns of one table against values in two columns in another table

Hi, as the title reads, I'm looking for an approach that will allow me to compare values in two columns of one table against values in two columns in another table.
Say, for instance, here are my tables:
Table1:
Server,Login
ABCDEF,JOHN
ABCDEF,JANE
FEDCBA,SEAN
FEDCBA,SHAWN
Table2:
Server,Login
ABCDEF,JOHN
ABCDEF,JANE
FEDCBA,SHAWN
In comparing the two tables, I'd like my query to report the rows in table1 NOT found in table2. In this case, it'll be the 3rd row of table one:
Server,Login
FEDCBA,SEAN
Thanks.

create table Table1([Server] varchar(50), Login varchar(50))
Insert into Table1 values ('ABCDEF','JOHN'),('ABCDEF','JANE'),('FEDCBA','SEAN'),('FEDCBA','SHAWN')
create table Table2([Server] varchar(50), Login varchar(50))
Insert into Table2 values ('ABCDEF','JOHN'),('ABCDEF','JANE'), ('FEDCBA','SHAWN')
select [Server] ,Login from Table1
Except
select [Server] ,Login from Table2
select [Server] ,Login from Table1 t1
where not exists(Select 1 from Table2 where t1.[Server] = t1.[Server] AND Login=t1.Login)
drop table Table1,Table2

Compare two members from the same dimension in HFR

Hi,
Is it possibe to compare two members from the same dimension in HFR? The requirement is to compare Year and Week members from the same dimension. The Week date will be selected from POV. The corresponding Year date should be displayed in the report. Week dates are in the format W2008-03-07 and Year dates are in YTD2008-03-07.
The dates are same except the preceding character.I am unable to compare these two. In my understanding there's no substring or replace functions in HFR.
Kindly help. Thanks in advance.
Regards,
Uma

Hi,
How is your database structured? it may be possible to use the 'RelativeMember' function if it will always be the same number of steps between the 'W' member and the 'YTD' member, e.g. if your hierarchy is something like:
Time
.Weeks
..W2008-03-07
..W2008-03-10 etc.. for 52 weeks
.YTD
..YTD2008-03-07
..YTD2008-03-10 etc.. for 52 weeks
In your report select 'Current Point of View for Time' in one row/column and in the other use:
RelativeMember set up as follows:
Member: Current Point of View for Time
Offset: 52
Hierarchy: Time
RelativeMemberList: Lev0, Time
UseFirstDescendant: leave unselected
Hope this helps

Combining the same column from 2 tables with distinct result.

I have 2 tables with identical name columns. One is current people and the other is historical people. I want a select that returns any name that is in either table. I want each name listed only once. I want to see 1 entry for each name if it is in the current table, the historical table, or both tables. I can easily do a select distinct on each table but how do I join the queries to get 1 result set with no duplicates? The name column is not a key field and I don't want any other columns from either table.

Just a simple UNION:
select name
from current
union
select name
from historical;

Two triggers on same table

Hi Friend.
I have to write two triggers on same table for auditing different columns of different users(may be different modules).
I will have an audit table in which i will insert data such as (user_id,module_id,column_name,old_col_val,new_col_val,timestamp)
Now different users from different modules will update the data on same table may be same columns from different front end forms!
If we write directly, we will not be able to know which column is updated by which user.
My question is in this case how can we control the triggers to raise differently?

You can use WHEN clause to fire a trigger only when some condition is true - you can check an user also,
look at simple example:
- suposse we have two users US1 and US2:

Commit complete.We want a trigger that is fired only by user US1 and only after update of COL1 and COL2
(COL3 is ignored):
SQL> connect us1/us1
Connected.
SQL> CREATE OR REPLACE TRIGGER Trig_123_US1
2 AFTER UPDATE OF col1, col2 ON tab123

8 END;
SQL> /
Trigger created.And we want a second trigger that is fired only by user US2 and only after update of COL2 and COL3
(COL1 is ignored):
SQL> connect us1/us1
Connected.
SQL> CREATE OR REPLACE TRIGGER Trig_123_US2
2 AFTER UPDATE OF col2, col3 ON tab123
3 FOR EACH ROW
4 WHEN ( user = 'US2' )

Trigger created.and now let test our triggers:
SQL> connect us1/us1
Connected.
SQL> update tab123 set col1 = 22;
1 row updated.
SQL> update tab123 set col2 = 22;
1 row updated.
SQL> update tab123 set col3 = 22;
1 row updated.
SQL> commit;
Commit complete.

US1                22         22
SQL> connect us2/us2
Connected.
SQL> update tab123 set col1 = 333;
1 row updated.
SQL> update tab123 set col2 = 333;
1 row updated.
SQL> update tab123 set col3 = 333;
1 row updated.
SQL> commit
2 ;
Commit complete.
SQL> select * from us1.audit_tab123;
USERNAME         COL1       COL2       COL3
US1                22          1
US1                22         22
US2                          333         22
US2                          333        333As you see, each trigger is fired only once, first triger only for user US1 and columns COL1 and COL2,
and second trigger only for user US2 and only after update of COL2 and COL3.
I hope this will help.

Want to update a column with different column of same table

I have a table TEST_CDR which is having 250 millions records also having partition by hash.
there are two column in this table ID and CDR_ID want to update ID in CDR_ID but it take too much time like 24 hours or more.
please suggest me a simple way.

Hi,
You can try this. but be careful about your backups and go through CTAS,nologging and parallel concepts...
Please refer this link.

1.CTAS with nologging and parallel..
SQL> create table test_cdr_1(id,cdr_id) nologging parallel as select id,id from test_cdr;
2.rebuild indexes, triggers and constraints to test_cdr_1
3.rename test_cdr to bkup_test_cdr;
4.rename test_cdr_1 to test_cdr;
