Table updation query

Hi All,
I have a table called X in that there is a field called account Number. Now i have created a table which consists of a field AccountNoRef. Now while inserting into this field a value called 0032 i need to check the table X whether that table consists the value 0032 or not. I want a procedure for thie query. Can anyone help me to do so.
Thanking you
Raghava

You don't want a trigger or procedure, because it is not needed and adds additional overhead. A foreign key is all you need really:
> I have a table called X in that there is a field called account Number.
SQL> create table x (account_number number(5) primary key)
2 /
Tabel is aangemaakt.
SQL> insert into x values (32)
2 /
1 rij is aangemaakt.
> Now i have created a table which consists of a field AccountNoRef.
SQL> create table a_table (accountnoref number(5) references x(account_number))
2 /
Tabel is aangemaakt.
> Now while inserting into this field a value called 0032 i need to check the table X whether that table consists the value 0032 or not.
SQL> insert into a_table (accountnoref) values (32)
2 /
1 rij is aangemaakt.
SQL> insert into a_table (accountnoref) values (32)
2 /
1 rij is aangemaakt.
SQL> insert into a_table (accountnoref) values (33)
2 /
insert into a_table (accountnoref) values (33)

Urgent help in multiple table update query

TABLE1
NAME
RATE
TABLE2
NAME RATE1 DATE1
NAME RATE2 DATE2
NAME RATE3 DATE3
Can anyone help me to write a query which can update RATE in TABLE1 based on
following criteria ?
We have same column 'NAME' in both the tables.
First Find maximum Date from the TABLE2 and then take correspoinding rate from TABLE2 and update with the RATE column in TABLE1.

Update Query is Performing Full table Scan of 1 Millions Records

Hello Everyboby I have one update query ,
UPDATE tablea SET
          task_status = 12
          WHERE tablea.link_id >0
          AND tablea.task_status <> 0
          AND tablea.event_class='eventexception'
          AND Exists(SELECT 1 from tablea ltask where ltask.task_id=tablea.link_id
          AND ltask.task_status = 0)
When I do explain plan it shows following result...
Execution Plan
0 UPDATE STATEMENT Optimizer=CHOOSE
1 0 UPDATE OF 'tablea'
2 1 FILTER
3 2 TABLE ACCESS (FULL) OF 'tablea'
4 2 TABLE ACCESS (BY INDEX ROWID) OF 'tablea'
5 4 INDEX (UNIQUE SCAN) OF 'PK_tablea' (UNIQUE)
NOW tablea may have more than 10 MILLION Records....This would take hell of time even if it has to
update 2 records....please suggest me some optimal solutions.....
Regards
Mahesh

I see your point but my question or logic say i have index on all columns used in where clauses so i find no reason for oracle to do full table scan,,,,
UPDATE tablea SET
task_status = 12
WHERE tablea.link_id >0
AND tablea.task_status <> 0
AND tablea.event_class='eventexception'
AND Exists(SELECT 1 from tablea ltask where ltask.task_id=tablea.link_id
AND ltask.task_status = 0)
I am clearly statis where task_status <> 0 and event_class= something and tablea.link_id >0
so ideal case FOR optimizer should be
Step 1)Select all the rowid having this condition...
Step 2)
For each row in rowid get all the row where task_status=0
and where taskid=linkid of rowid selected above...
Step 3)While looping for each rowid if it find any condition try for rowid obtained from ltask in task 2 update that record....
I want to have this kind of plan,,,,,does anyone know how to make oracle obtained this kind of plan......
It is try FULL TABLE SCAN is harmfull alteast not better than index scan.....

Update query issue to update middle (n records) of the rows in a table

Hi
I have a below requirement for that I gone thru one below appoch to fulfill my requirement.
Requirement:
I need to pull 3 crore data thru ODI, source table does not have a primary key and it have 200 columns with 3 crores records (it has a 25 columns as composite key).
I need to populate those 3 crores records into target oracle DB but when I tried to load 3 crores at time I got an error so I approch incremental load, since for that I need to update for each 1 crore records with flg1,flg2 anf flg3 (flag values), for this update I have added one more column in source table using those flag values I can populate 1 crore records in target machine.
Approch
For aove requirement I writem below query to update flg1 for first crores records update tbl_name set rownum_id='flg1' where rownum<=10000000; and it updated successfully without any error, for second, to update flg2 for 2nd crore records I wrote below update query and it execute 20min and given *0 rows updated* Please help if below query is wrong
Query: update tbl_name set rownum_id='flg2' where rownum<=20000000 and rownum_id is NULL;
Thanks in advance

Phanikanth

A couple of thoughts.
1. This forum is in English and accessed by people in more than 100 countries. Use metric counts not crore. Translate to million, billions, trillions, etc.
2. No database version ... makes helping you very hard.
3. 200 columns with 25 in a composite key is a nightmare by almost any definition ... fix your design before going any further.
4. What error message? Post the complete message not just your impression of it.
5. Oracle tables are heap tables .. there is no such concept as the top, the bottom, or the middle.
6. If you are trying to perform sampling ... use the SAMPLE clause (http://www.morganslibrary.org/reference/select.html#sssc).
7. What is ODI? Do not expect your international audience to know what the acronym means.

UPDATE QUERY can't update table

Hi,
During 1500-2000 concurrent users, DB Transaction locks occur. So that Update query can't update table and we get inconsistent data. How can we avoid this inconsistent data?? Why we get transaction locks??
Eg. In update query it update the status of user with completed; but because of transaction lock update query can't update status of user it remains uncompleted. So we can get wrong status of user(inconsistent data). Why UPDATE query update the status
of user???
update table set status='completed', date=@p2,score=@p3 where id=@p1

You are not getting inconsistent data, you are getting the data according to the isolation level you are running under. The isolation level determines the locking model and therefore determines any bad dependencies you may experience. Reducing the bad dependencies
through higher isolation level will lower concurrency. *This* is the core concept of Transactional Processing theory.
Furthermore there is not really such a thing as a DB Transaction lock - at least not in the way you mean. SQL server does use DB locks (such as Shared transaction workspace and Exclusive transaction workspace) but the highest level of lock escalation is
the object level (heap or btree) so those are the things you are really interested in. In the ideal would you want all Exclusive, Shared and U locks to be taken at the RID (heaps) or Key (cluster tables) level - and only have few of them per query.
In conclusion think carefully about your query and how it is implimented under the covers by the database engine.

Single Update query for multiple tables

Is it possible or how can i do it, help me out.

Fetch Insert / Update Query From Table Trigger

Hi everyone !,
I have a situation, is there any way where I can get insert/update query by before-insert / after insert trigger when a user inserts/updates any row in the table.
Plz....help me....champs.....
Regards,
Naushad

That was a nice thing but it works only on some oracle 9i with DML statements.
On database versions 9.2.0.1 to 9.2.0.6 ora_sql_text works and returns the calling text for dml triggers, where as starting from 9.2.0.7 the behavior has changed and returns NULL.
Cause
This issue had surfaced from 9.2.0.7.0 patchset. After discussions in Bug 4171597 which was closed as a duplicate of Bug 4230721 it was concluded that it was the expected behavior i.e ORA_SQL_TXT should return null when dml triggers are used.
ORA_SQL_TXT is a "System defined event attribute" and is supposed to work only with "System triggers". This is also what the Documentation says - "Application Developers Guide : Fundamentals(9.2)
Chapter 16 Working with System events".

Update Query based on a reference to another table

I have a table TableA which contains two columns PKey, EmployeeID.
I have anohter table TableB which contains FName, LName, City, State and a reference key TableA_PKey referenced to PKey in TableA.
I want to update TableB and set the values of TableB.State = 'CA' where TableA.EmployeeID in (111, 222, 333)
How do I write this update query? thanks

Hi,
This does what you requested:
UPDATE tableb
SET     state     = 'CA'
WHERE     tablea_pkey IN (
                        SELECT pkey
                   FROM    tablea
                   WHERE   employeeid     IN (111, 222, 333)
;Whenever you have a problem, it helps if you post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables, and the results you want from that data.
In the case of DML problems (including UPDATE), the sample data should show what all the tables are like before the DML, and the results will be the contents of the changed table after the DML.
Always say what version of Oracle you're using.

Insert and update query to calculate the opening and closing balance

create table purchase(productid number(5) ,dateofpurchase date,
qty number(5));
create table inventory(invid number(5),productid number(5),
idate date,openingqty number(5),closingqty number(5));
Records in inventory:
1,1,'01-jan-2009', 10, 20
2,1,'03-jan-2009', 20, 30
3,1,'04-jan-2009', 40, 50
when I enter the purchase invoice for 15 qty on 02-jan-2009
after say '15-jan-09' , a new record should get inserted
with opening balance = (closing balance before 02-jan-2009)
and all the opening and closing balance for that product should
get affected.
If the invoice for 20 qty is entered for the existing date say
'03-jan-2009' in inventory , then the closing balance
for 03-jan-2009 should get updated and all the following records
should get affected.
I need the insert for the first one and update query for the
second one.

<strike>You can do this in one statement by using the merge statement</strike>
Hmm, maybe I spoke too soon.
Edited by: Boneist on 25-Sep-2009 13:56
Thinking about it, why do you want to design your system like this?
Why not simply have your purchases table hold the required information and then either work out the inventory on the fly, or have a job that calls a procedure to add a row for the previous day?
If you continue with this design, you're opening yourself up to a world of pain - what happens when the data doesn't match the purchases table? Also when is the inventory cut-off to reset the opening/closing balances? Monthly? Annually? Weekly? If it's set to one of those, what happens when the business request the inventory for a particular week?

About update query

Hello :),
I am a MS SQL Server expert [;)]. trying to learn ORACLE.
I tried to assign some value to a variable in an update query. I got error message that virtual columns are not allowed. This is very important to get rolling effect.
Can some one please guide me about how to get rolling effect if we can not assign a value to a variable in an update query.
Thanx in advance.

Sender jdbc adapter - no update query

hi ,
i am using pi 731 single stack.
the scenario is - PI has to pick data from view of a hana database. i am using jdbc sender for it.
pi will not have access to update the table,only pi can read the view of database.So,PI can't use UPDATE query.
If in jdbc sender channel ,I use SELECT query only and no UPDATE query - will it work ? what will happen if there are 100 records in the view and PI failed after fetching 43 records..will it pick from 44th record next time OR it will start from 0 again ?
rgds

Hi SAP PI,
It has no sense to use the sender JDBC without update query because then always will be taken the same records.
If you cant update the source DB you only have the choice to talk with the DB administrators that they develop for you a stored procedure that it has to do the work to get different records in every PI access.
If the PI record process fail with impossible source database update update, the only way (afaik) is to do a PI alert and to communicate it to db sender administrators. There are another option like to store the data in a intermediate table, and so on but all possibilities that i can think now are not to enough good.
Regards.

Update query not working in the JDBC sender Communication channel

Hi,
We are working on JDBC to File scenario. As per the configuration, XI should pick the data from SQL database every 20 secs and should update the corresponding flag. We are using subquery in the select and update statement as both header and detail tables are involved.
Now the issue is, select query is working fine but update statement is not working as expected. It is somehow updating some other records rather than doing for the ones selected by the adapter.
Moreover logSQLstatement is also not working. Hence we are unable to identify the records which are getting updated.
Please advise.

Hi Rumi,
See Question 8. Transaction Handling (Sender) in [SAP Note 831162 - FAQ: XI 3.0 / PI 7.0 / PI 7.1 JDBC Adapter|https://websmp130.sap-ag.de/sap(bD1wdCZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=831162].
8. Transaction Handling (Sender)
Q: If I have the following configured in a JDBC Sender:
Select Query:
SELECT column FROM TABLENAME WHERE FLAG = "TRUE"
Update Query:
UPDATE TABLENAME SET FLAG = "FALSE" WHERE FLAG = "TRUE"
How do I know that the JDBC adapter will not update newly added rows (rows that were
added between the time that the SELECT and UPDATE queries were executed) that were
not read in the initial SELECT query?
A: The SELECT and the UPDATE are run in the same DB transaction, i.e. both statements
have the same view on the database.
Make sure that both statements use the same WHERE clause. An additional
requirement for the correct operation of this scenario is the configuration of
an appropriate transaction isolation level on the database
(i.e., repeatable_read or serializable). You might also consider using a
"SELECT FOR UPDATE" statement instead of a plain SELECT statement to
ensure proper locking on the database. "SELECT FOR UPDATE"
is not supported in MS SQL database. In this case please make use of an
appropriate transaction isolation level on the database. For more details
please contact your DB vendors.
After, see Transaction Handling Issues in [SAP Note 1039779 - JDBC Adapter issues(Escape character,Transaction handling)|https://websmp130.sap-ag.de/sap(bD1wdCZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=1039779].
