Add value to existing update statement registration
I have a column with values (for Ex: $3000) and now I want to add $1,000.
How can I add to it with just a statement.is update it all the functions to use like add_months?
Note: I don't want to get the 3000 first and add 1000. I'm looking for a direct update to this additional column with $1,000.
Thank you

Essbase "add to the existing values.
It must add value to data Essbase using ODI.
For example: in the Essbase cell is a value of 10. In a source of 5 should be in cell 15 Essbase.
The procedure as a data load using the Essbase rule where I can put the parameter "overwrite the existing values" or "add to the existing values.
I can do using ODI?
Of course, I can export Essbase Data Oracle DB, compute new values and return to the Essbase charge. Can be easy way?
Thank you.Hello
In your interface and under the IKM "IKM SQL for Hyperion Essbase (data") there is an option for a rule to load "RULES_FILE".
This means that you can use a rule to support essbase, in the State of charge you can set under "Data loading settings" > "add to the existing values.See you soon

ODI Dataload 'Add to the existing value' in Essbase
ODI 11.1.1.6 supports the function "add to the existing value" for the Essbase data loads or do we need we must always use a rules file?
We currently using the rule files into the interface to load the Essbase as our ODI 10.1.3. does not support this feature.
Published by: user729857 on November 12, 2012 07:07You should not use a rule of the load, using a load rule provides additional features and it is the optimal way to load data with the essbase KM

Question about the update statement
Hi all
UPDATE table_name
SET Column1 = value, column2 = value2
WHERE condition;
I have an update like this statement. What happens when I run the above statement, when there is no column named Column2 in the table? If it creates a column named column2 and value2 using?
Instead should first create a new column named Column2 in the table first and then run this update statement?
Please, someone good to explain.Hi, this statement (it is a dml statement) will give an error, because the Column2 does not exist in the table. You must add the Column2 by an alter (ddl statement) statement. Then, you can try to execute your statement.
Kind regards

Performance issue with the Update statement
Oracle 10204
I have a problem related to updaing one performance table.
only 5000 lines should be updated.
Hir are some details on the tables/M.V concerned:
I tried to run the update with two options:TABLE_NAME LAST_ANALYZED NUM_ROWS SAMPLE_SIZE PS_RF_INST_PROD 1/20/2010 1:14:22 AM 7194402 7194402 BL_TMP_INTRNT 1/27/2010 9:08:54 AM 885445 885445 NAP_INTERNET 1/25/2010 11:47:02 AM 7053990 560777

2. with notes I added.
In both cases I he collapsed after more than an hour.
Can any one suggest how to speed it up?

need help with the Update statement
Hello
I received a question in a course and I tried my best to respond, and now my brain is giving. I would really appreciate help with the update statement. I don't mind if you do not validate a solution, a little nudge in the right direction would be really useful. I'll post that I got.
THE QUESTION
/ * For these agents disabled on more than seven missions, change their date of deactivation of the first date of deactivation of all the agents that have been activated in the same year as the agent that you update currently.
*/
I have it divided into parts, here is my select statement to agents disabled on more than 7 missions, which produces the deactivation_dates in the agents table that I want to update...
.. .and the code for the first date of deactivation for each year of activation agentSELECT s.deactivation_date FROM ( SELECT a.deactivation_date, count(m.mission_id) as nomissions FROM agents a INNER JOIN missions_agents m on a.agent_id=m.agent_id GROUP BY a.deactivation_date ) s WHERE s.nomissions>7 AND s.deactivation_date IS NOT NULL
..... I am not real to marry these two statements together in the Update statement. I can't extract each date of deactivation produced in the first select statement and their match against the first date of deactivation in the year they have been activated for the second select statement.select a2.deactivation_date from agents a2 where a2.deactivation_date= ( select min(a.deactivation_date) from agents a where to_number(to_char(a.activation_date,'YYYY'))=to_number(to_char(a2.activation_date,'YYYY')) )
Any help greatly appreciated... :))I began to wonder how things would :)

First of all why he chooses the date the earliest of all agentsUPDATE AGENTS_COPY AC /* (1) */ SET DEACTIVATION_DATE = ( SELECT MIN(AGS.DEACTIVATION_DATE) FROM AGENTS_COPY AGS , AGENTS_COPY AC /* (2) */ WHERE TRUNC(AGS.ACTIVATION_DATE,'YEAR') = TRUNC(AC.ACTIVATION_DATE,'YEAR') /* (3) */ )He recovers as soon as the subquery has not been correctly set in the SET clause. It seems you are trying to update a correlated, but we are still having a conceptual shift. I have added a few comments to your code above and below will explain.
(1): when you do a correlated update it is useful to the table alias that you did right here.
(2): this table statement is not necessary and is the reason why the FIRST deactivation date is selected. The alias that you use (3) refers to THIS table, not the one defined in the update statement. Remove the line indicated by (2) in the FROM clause and a correlated update will happen.
and secondly why is it to update each row, when I thought that I'm just the lines where the agents are disabled and missions > 7? Pointers on where I'm wrong would be very appreciated. (SQL = stupid query language!) :)
user8695469 wrote: then why is it to update each row, when I thought that I'm just the lines where the agents are disabled and missions > 7? Pointers on where I'm wrong would be very appreciated. (SQL = stupid query language!) :)
WHERE EXISTS ( SELECT a.agent_id, count(m.mission_id) FROM agents a /* INNER JOIN AC ON AC.AGENT_ID = A.AGENT_ID */ INNER JOIN missions_agents m ON a.agent_id=m.agent_id GROUP BY a.agent_id, a.deactivation_date HAVING count(m.mission_id)>7 AND a.deactivation_date IS NOT NULL )Once again this problem is similar to the question above that a correlation update doesn't work. Test existence of lines in an EXISTS subquery. Since your subquery is not related to the table that you are trying to update, it will be always return a line and, therefore, it returns true for EACH LINE in the AGENTS table. To limit the game to only agents > 7 missions results, you need to add a join condition that references the table in your update statement. I added one above (with comments) as a sample.
I recommend you look over all material that you have associated with correlated subqueries, including documents that I posted above. This seems to be what you're having the problem more with. If you need me to explain the concept of correlated queries any better please let me know.
Thank you!

The UPDATE statement: view Multi level Inline.
This is the test case.
Now I want to update target.val with source.val and the corresponding condition is source.old_val = target.valcreate table source(old_val integer, new_val integer) / create table target(val integer) / insert into target values(1) / insert into target values(2) / insert into target values(3) / insert into source values(1,4) / insert into source values(1,5) / insert into source values(2,6) / insert into source values(3,7) / insert into source values(3,8) / commit /
But source.old_val can have multiple values for a given target.val. You can see in the example. I would like to order by ROWID of source and choose the first record.
So I wrote an UPDATE.
and that's what I got.SQL> update target t 2 set (val) = (select new_val 3 from (select new_val, row_number() over(order by rowid) rno 4 from source s 5 where s.old_val = t.val) 6 where rno = 1) 7 where exists(select null 8 from source s 9 where t.val = s.old_val) 10 / 3 rows updated.
I expected the updated as 4,6,7 or 5,6,8 value but don't know why its 4,4,4.SQL> select * from target 2 / VAL ---------- 4 4 4 SQL> select * from source 2 / OLD_VAL NEW_VAL ---------- ---------- 1 4 1 5 2 6 3 7 3 8
Just try to understand how this update is underway. Not sure if I am missing something basic.
NOTE: I'm interested in the behavior of this update statement and not another method to solve the problem.
Thank you
Knani.Well, I think that it is related to the #374632.1 bug, already discussed in [this thread | http://forums.oracle.com/forums/thread.jspa?messageID=2134151]
In short, your case should return the error I, ORA - 904.Nicolas.

How to tune this update statement?
Hello
I have to solve the following task:
Update all rows in table A, which has an appropriate row in table B and save what you have done in a table of newspaper.
It is possible that there are several assembly lines in the table has a row in table B.
My first approach is a loop above the table B and do an update of table A for each entry in table B.
It works and looks like this:
Table A:
Number of PK (this is the primary key for this table)
The KEY number
Table B:
Number KEY_OLD
Number KEY_NEW
Table of newspaper:
Number of PK
Number KEY_OLD
Number KEY_NEW
Given that the table B can have up to 500,000 entries (and table A has more entries) this solution causes a lot of update statements.declare TYPE PK_TAB_TYPE IS TABLE OF number INDEX BY BINARY_INTEGER; v_tab_PK PK_TAB_TYPE; v_empty_tab_PK PK_TAB_TYPE; begin for v_rec in (select * from table_B) loop v_tab_PK := v_empty_tab_PK; /* clearing the array */ update table_A set KEY = v_rec.KEY_NEW where (KEY = v_rec.KEY_OLD) returning PK bulk collect into v_tab_PK; if (v_tab_PK.count > 0) then for i in v_tab_PK.first..v_tab_PK.last loop insert into TMP_TAB_LOG(PK, KEY_OLD, KEY_NEW) values (v_tab_PK(i), v_rec.KEY_OLD, v_rec.KEY_NEW); end loop; end if; end loop; end;
I'm therefore looking for a solution that offers better performance.
My second approach was using a correlated update and looks like this:
Now, I found that a single update.declare TYPE PK_TAB_TYPE IS TABLE OF number INDEX BY BINARY_INTEGER; v_tab_PK PK_TAB_TYPE; v_empty_tab_PK PK_TAB_TYPE; v_tab_NewKey PK_TAB_TYPE; begin v_tab_PK := v_empty_tab_PK; /* clear the arrays */ v_tab_NewKey := v_empty_tab_PK; update table_A a set KEY = (select KEY_NEW from table_B where (KEY_OLD = a.KEY)) where exists (select 'x' as OK from table_B where (KEY_OLD = a.KEY) ) returning PK, KEY bulk collect into v_tab_PK, v_tab_NewKey; if (v_tab_PK.count > 0) then for i in v_tab_PK.first..v_tab_PK.last loop insert into TMP_TAB_LOG_DUB(PK, KEY_OLD, KEY_NEW) values (v_tab_PK(i), null, v_tab_NewKey(i)); end loop; end if; end;
The only thing missing in this second approach is the old KEY before the update in the log table.
But I have no idea how to do to get the old value.
Is it possible to change this second approach to get the old value of the KEY before the update to write it in the table of the newspaper?
And now I need your help:
What is the best way to get a high-performance solution for my task?
Any help is appreciated.
Hartmut cordiallyHave you tried my advice to make a UNIQUE on table_B (KEY_OLD) index?
Oracle wants to make sure that the update statement are left with two different values for the update of a line:
The keys must be preserved in the online posting. -

I don't understand why it takes too long...
Could you please help me on this fix, please...
It's the details on the table,
Total number of records: 35 M record
Validation interval: 500 records / commit
Total scores: 3
total number of columns: 95 - including primary, unique and foreign key columns (all columns will be updated for each update because update from the app online)
Total no of the foreign key columns: 12
Unique key column: 1
Total index: 27 ( including the key index foreign 12 + 1 + 1 index of primary key Unique key index )
example of update statement,
UPDATE DIRECTORY_LISTING_STG SET COLUMN_1 = :VAL_1 . . . COLUMN_94 = :VAL_94 WHERE RECORD_KEY = :P_KEY_VAL;
The table is.

Hello
I am updating table via an application using Hibernate jdbc connection online.
If the update statement will be sent to the database in a pack of 500 documents (batch update).
Thanks Ram
line-by-line UPDATE is slow by slow transformation
In Oracle no other session can 'see' upgrade from uncommitted changes.
The only way to significantly reduce the elapsed time is to have only 1 UPDATE & 1 COMMIT!

Hi all
I have here is the update statement in my code
UPDATE equip_stg stg
SET stg.err = 'WRC '.
WHERE DOES NOT EXIST (SELECT *)
FROM (SELECT stg.*
Of equip_stg stg.
REASON_SETUP sea
WHERE stg.equipment_fk = mer.equipment_pk
AND stg.downtime_reason_code = mer.reason_code
AND ((stg.status = 3 AND sea. REASON_TYPE = 1)
OR (stg.status = 2 AND sea. REASON_TYPE = 3)
OR (stg.status = 1 AND sea. REASON_TYPE = 4))
ERS stg.downtime_reason_code AND IS NOT NULL)
WHERE ers.equipment_fk = stg.equipment_fk
AND ers.downtime_reason_code = stg.downtime_reason_code
)
AND stg.status IN (3,2,1)
AND stg.downtime_reason_code IS NOT NULL;
The statement above sets updated the column equip_stg in WRC if err for corresponding material and reason, there is no line in the REASON_SETUP table.
I want to change the code above so that the validation above is first done with REASON_SETUP according to equipment and column of type of reason. Is there is no line for this type of material and the reason in this table, then he must hit lookup table. Example, I have data from equipment EQP1, status = 3, then it should check if REASON_SETUP has everything save for EQP1 equipment and the reasoning of type 1. If she made the next record should be validated on the table otherwise come file should be validated against the lookup table. For the table of choice also I have same join conditions
STG.equipment_fk = lookup.equipment_pk
AND stg.downtime_reason_code = lookup.reason_code
Thanks in advance.
Kind regards

Hello
I think I see. All lines for each (equipment, reason_type) will be removed completely on a table or another. reason_setup if possible and looking as if this combination never occurs in reason_type. Another way to say it is that you want only (equipment, reason_type) groups of the best tablle, where reason_type is better than search. Exactly what made a Request Top - N . Here's a way to do it:
UPDATE equip_stg
SET err_code = "WRC".
WHERE (equipment, downtime_reason_code) NOT IN
(
WITH union_data AS
(
SELECT 'A' preference AS, reason_code, reason_type, equipment
OF reason_setup
UNION ALL
SELECT equipment, reason_type, reason_code, 'B' AS preferences
SEARCH
)
got_r_num AS
(
SELECT equipment, reason_type, reason_code
DENSE_RANK () (PARTITION BY MATERIAL, reason_type
ORDER OF preference
) AS r_num
Of union_data
)
SELECT equipment
DECODE (reason_type
1, 3
3, 2
)
reason_code
OF got_r_num
WHERE r_num = 1
)
;
To see how this works, reconstruction of the NOT IN subquery, step by step. First run just union_data as a stand-alone application. When you understand what it does, run got_r_num and when you see what he's doing, run the set NOT IN subquery.

I don't know the reason why at first sight, but it is obvious that the inner nested loop was doing a lot of work (full index scan).
My first thought was to rewrite the query in a merge statement.
Perhaps leads to a more effective plan and so no need to delve deeper into the issues you have raised ;-)
merge into FUS PFA_FUSIONFACC

How to optimize the update statement so that the query is reading the same table?
Hi all
I have a process with the following UPDATE statement:
Sales_val update
SET ship_date =)
Select max (hist.ship_date)FROM sales_hist hist
WHERE hist. X_ID = A.X_ID
AND hist. X_VAL = A.X_VAL)
) WHERE EXISTS (select * from sales_hist hist where )
WHERE hist. X_ID = A.X_ID
AND hist. X_VAL = A.X_VAL
)
sales_val - 50 lines mln (unique index)
sales_hist - 20 mln ranks (unique index)
I met many problems with waits and locks - how to optimize to avoid locks using the parameters of tables or changes of the declaration? or maybe is there another way to do optimization ?
Kind regards
Bolo
Thank you for that. Collect in bulk Unfortunatelly + FORALL does not work with the types in 10g - solution is to use the FOR loop and is not as effective as FORALL in many cases. I do still some tests to solve this problem - I'll put you once it's done.
EDIT: hash partitioning + fusion - 3-5 minutes (time), so for now it's the solution to the problem. Thank you all for the great discussion!

He is an example for adding records in this block. I need to add the values of the quantity of each time when it has updated. Entering the first record(value=5) the total should display 5. When you enter the second value(value=6) the total should be 11. And if it changes in accounts are rendered already entered the total value must be updated. Please help me do this in oracle forms.
Hey, Moris,.
For the contents according to your requirement, create a block and put an element contained in this block that reside on the same canvas.
Then below mentioned property BLOCK for newly created block:
- Single disc: Yes
Then set below mentioned ELEMENT of property for the newly created item:
- Data type: number
- Method of calculation: 'summary '.
- Text-to-speech function: "sum".
- Block in summary: block that you created
- Point summary: Point you have created
I hope it will work for you, I tested and works great.
Thank you
