Compare two rows in a same table
Dear all
I need to compare two rows in the same table, I dont know hoe to do it in pl/sql. Some one please help me on this.
example:
tr br price
xya0001 ama7 12
xya0003 ama6 14
xya0004 ama7 16
in the table tr is a unique value for each row, I need to compare price column and see whether the first value is less or greater than the next value and, if it is greater put the corresponding br value to a variable and if it is smaller put the corresponding br value to another variable. I dont know a method to do it, as I'm new to pl/sql. Some one please help me in this
not sure what you intend to do as you have mentioned that "TR" is unique and you just want to compare each record with just the next record. Hope below query helps. The value "G" or "L" in flag would indicate if the current records price is greater than or less than the price in next record.
select tr,br,price,col4, case when price> col4 then 'G' when price< col4 then 'L' end flag from (
select tr,br,price,lag(price,1,0) over(order by tr) col4 from testcomp
)

SUM two ROWS in the SAME Table
Hi,
I have a problem with this issue. I want to sum two rows from the same table, but I don´t know how to do that. I tried to do it with CTE, but always I get the same error "Ambiguous". I would like to ask you, if there is other manner to get that
data (sum two rows) and if it is possible to see examples about it.
Thank you in advanceHi Vaibhav,
I leave you my scrip:

Compare two results from the same table
i have two results from the same table that i would like to compare. below is my query and the results i want to compare
SELECT tblItemRoutingBOM.ItemRevID, tblItem.ItemID, tblItem.PartNum, tblItem.ItemName, tblItem.ManufacturerPartNum AS [Mfg Part#], tblItemRoutingBOM.Quantity
FROM tblItemRouting
INNER JOIN tblItemRoutingBOM ON tblItemRouting.ItemRoutingID = tblItemRoutingBOM.ItemRoutingID
INNER JOIN tblItem ON tblItemRoutingBOM.ItemID = tblItem.ItemID
WHERE tblItemRoutingBOM.ItemRevID in (61,70)
as you can see i am returning two records using the where clause
ItemRevID, ItemID, PartNum, ItemName, Manufacturer, Mfg Part#, Quantity
61,121,331503,.233 Aluminum Sheet,,1
70,121,331503,.233 Aluminum Sheet,,3
now what i am looking for is to combine these two together into one row with the following added. two columns for each QTY, QTY1 = 1 and QTY2 = 3 with a third column added that is the difference between the two QTY Diff = 2
Any thoughts?Here are the two statements that i want to combine, results for each are attached
SELECT tblItem.ItemID, Sum(tblItemRoutingBOM.Quantity) AS SumOfQuantity, tblItem.PartNum AS [Part #],
tblItem.ItemName, tblManufacturer.ManufacturerName AS Manufacturer, tblItem.ManufacturerPartNum AS [Mfg Part#]

my returned result should combine above with two extra columns (two extra columns because i have two results to combine)

Columns go as such, ID, QTY1 (for 61), QTY2 (for 70), Diff (QTY1-QTY2), PartNum, ItemName, Mfg, Mfg Part#
IF the results from one of those two are empty then i would see something like this
114, 11, 0, 11, 55002, Pepsi Blue Cap, NULL,
117, 5, 0, 5, 331501, Marigold Yellow For ABS, NULL

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.
RegardsHi ,
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.

Comparing two rows field by field through a loop
Hi all,
I've got a tricky issue:
There are two tables (almost) identically designed;
In the first one there are lets say some new data and in the 2nd one there is data to be hold & adjusted;
I built up a third table, which contains the meta informations about the two other tables (i.e. it describes the tables, so for each field of these tables, there is the field name, field type, primary key marker, etc.);
The challenge now is, how can I compare two rows (of the same primary key) field by field and get out the differences (and adjusting the target table row) using PL/SQL procedures/functions.
I thought a create a cursor over the 3rd table and call functions to get the fields out (given by the field name of the cursor), compare the two fields and return if it's equal or different...
As I've seen, there is now direct way to replace a field name in a statement - but how to resolve this with a cool workaround?
In addition, there are about 120 pairs of such tables, to be compared in the same way - so I decided to prevent creating hard coded design for the software.
Even the selection of a pair of rows from the two tables should be parameterized, 'cause the primary keys are of course different in the 120 table pairs.
Any hints or suggestions?
Thanks in advance & regards,
PeterHi Peter,
I am very far from being an expert in Oracle but, everything I've read so far strongly suggests that PL/SQL is often the fastest among the customized solutions (beating even compiled C code). The reason - from what I've understood - is that PL/SQL is part of the Oracle kernel/engine, other languages simply aren't.
I suggest you do your own research to confirm what I've just said above.
On a completely different note, when I first read your post, I started writing a reply and decided to discard it because, I figured you probably would find it too far off your original thoughts. However, then you wrote:
>
There are some reasons to prevent hard coding, but it may be possible to generate the PL/SQL-code for each pair of tables by an external program.
>
This is exactly what I was mentioning in the post I ended up discarding. The basic step by step process I was going to mention is as follows:
STEP 1: If possible, write one PL/SQL program that does the job properly for one set of tables. Test it thoroughly and identify potential differences in the process if it had to be applied against other tables. Make it as generic as reasonably possible, that is, keeping the code as simple as possible.
STEP 2: turn the working code of step 1 into a template (usually replacing table names, columns, etc by some token that would not be a valid name).
STEP 3: generate a list of the tables and their corresponding columns you need to process. This list may need to be massaged a little to become the generating seed of 120 programs (or so based on what you've said).
STEP 4: if you don't know Perl or AWK then (don't be alarmed...) download AWK (not Perl) and learn it... you can learn the thing in a couple days (maybe even less). It is a very simple and straightforward text processing language, I know non progammers that learned enough in one day to do useful things with it. Using AWK you can easily generate the 120 programs you need from a working template in very little time (a few hours after you've become proficient). By the way, there is AWK, GAWK, NAWK, all pretty much the same thing and all free. The standard manual for AWK is the one written by the authors Aho, Weinberger and Kernigan, about 100 small pages, it's an easy read and no programmer should be without it :) (better than American Express!)
What you've described sounds just like the thing to use AWK for. I once used AWK to generate 27,000 (that's 27 thousand) lines of COBOL code, debugged and fully tested in 2 days! (testing was automated using AWK too!) It would have taken much longer to just type all that code.
Anyway, I hope that gives you something to think about and be of some help.

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 appreciatedWelcome 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.

How to compare two rows in PL/SQL?
Hi All,
How to compare two rows in PL/SQL? Is there any method that I can use instead of comparing them column by column?
Any feedback would be highly appreciated.PhoenixBai wrote:

If you're talking of rows within a PL/SQL associative array there are techniques as described in the documentation... e.g.

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,
UmaHi,
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

Trigger in mutation - Update another rows in the same table with a trigger

I try to do a before update trigger on a table , but the trigger is in mutation. I understand why it do that but my question is :
How can I update other rows in the same table when a UPDATE is made on my table??????

END;A standard disclaimer, the mutating trigger error is telling you that you really, really, really don't want to be doing this. It generally indicates a major data model problem when you find yourself in a situation where the data in one row of a table depends on the data in another row of that same table. In the vast majority of cases, you're far better off fixing the data model than in working around the problem.
If you are absolutely sure that you cannot fix the data model and must work around the problem, you'll need
- A package with a collection (or global temporary table) to store the keys that are modified
- A before statement trigger that initializes the collection
- A row-level trigger that adds the keys that were updated to the collection
- An after statement trigger that iterates over the data in the collection and updates whatever rows need to be updated.
If you're on 11g, this can be simplified somewhat by using a compound trigger with separate before statement, row-level, and after statement sections.
Obviously, though, this is a substantial increase in complexity over the single trigger you have here. That's one of the reasons that it's generally a bad idea to work around mutating table exceptions.

Two triggers in the same table and event
If I created two triggers on the same table and event (before insert), which of them will be triggered first ?...
The problem from the beginning is that I created the second one as after insert and in the body of the trigger I wrote (:new.xxx:= value) ... then an error (that it should be before insert trigger or update trigger), so I created it as before update ,,, but I have already before update trigger (for primary key)..... and the problem -I think- which of them start first...
Can make the second one as after insert and make update statement instead of assigning (:new.xxx:= value).....
RegardsIf I created two triggers on the same table and event
(before insert), which of them will be triggered
first ?...As already mentioned, prior to 11g the order of firing is undetermined.
The problem from the beginning is that I created the
second one as after insert and in the body of the
trigger I wrote (:new.xxx:= value) ... then an error
(that it should be before insert trigger or update
trigger), so I created it as before update ,,, but I
have already before update trigger (for primary
key)..... and the problem -I think- which of them
start first...If there is a conflict of interest inside the code then you will have to alter your design principle around this to cater for it. Also consider combining the code into a single before insert trigger to prevent any confusion.
Can make the second one as after insert and make
update statement instead of assigning (:new.xxx:=
value).....Attempting to update or query the same table as is causing the trigger to fire will result in a mutating table error. You can't do this. -
Comparing two data records of same IDOC
Hi,
In PI, we need to compare two data records of same IDOC to figure out if what type change occurred. For example, BENFIT3 IDOC contains data records tilted "E1BEN04". When there are multiple "E1BEN04" data records, then we need to compare the data inside them to see whether name, or data of birth or SSN is changed.
Has anybody came across this before. Your help is much appreciated.
Thanks
-TejaIf it is very few fields then you could use graphical mapping to determine the changes.
