Correlated update

Hi all,
i have a problem with running a update.
I have written this script
UPDATE artikel orgineel
SET "verkoopprijs" = (SELECT up_verkoop
FROM kun_up nieuw
WHERE orgineel."Nr_" = nieuw.UP_NR);
running this script gives me the followinf response from the server:
SET "verkoopprijs" = (SELECT up_verkoop
ERROR at line 2:
ORA-01722: invalid number
What is happening here? Both the columns are of the same type. (varchar2) and the data inside the columns is the same.
Somebody?????
Regards Johan Louwers

Hi Johan....
I'd say that Oracle is converting one of VARCHAR2's into a NUMBER - and is having trouble.
Why Oracle is doing that is a good question. A DESCRIBE of the two tables would be helpful to understand why.
Hope this helps, Good Luck.

Global correlation update

Hi,
Will the IPS go offline during a global correlation update? We are running sensor version 7.1.(7)E4 and are noticing drops due to the IPS being unavailable. The timing of theses matches global correlation updates on the IPS.

We are receiving the following log entry when global correlation updates.
%ASA-3-420001: IPS card not up and fail-close mode used, dropping TCP packet from InterfaceA:x.x.x.x/xx to InterfaceB:y.y.y.y/yy

Hello,
I have received following error in IPS regarding global correlation update
A global correlation update failed: ExecLoadCollabUpdate control transaction failed: Control transaction cannot be completed at this time
is any one aware about this error? is it major issue and affecting IPS? I think this is because correlation update failure. Please let me know if any one has more information on this error

Correlated Update ANSI style

Want to rewrite:
Update table fred
set description = ( select description from detail_table
where fred.type_col = detail.type_col )
Into ansi style ie. using 'join x on ' syntax how is it done?
Thanks in advance.

That will only work if you can satisfy oracle that you are key-preserving the joinTrue.
But the same general problem applies to correlated updates and merge. If the correlated subquery returns multiple rows, you'll get the "single row subquery" error. If merge finds multiple rows in the using table, you'll get the "stable set of rows" error.
One advantage to updatable views is that Oracle will throw the exception immediately (which is good if you're about to update a few million rows).
But I agree that updatable views don't often work because of the key preserved problem.
There have been several times I've tried them, but no go.

Question on correlated update

Greeting gurus. I expect the following demo will get id populated as 1.2.3.....100 but its all 1. why or why not working ?
create table ynot ( id number, sd date)
insert into ynot(sd)
select sysdate + rownum from dual connect by level < 101
select * from ynot
update ynot xx set xx.id = ( select row_number() over (partition by null order by sd ) from ynot yy where xx.sd = yy.sd )
select * from ynot

Table ynot has 100 different values for sd (today +1 to today +100)
The subquery asks for rows
from ynot yy where xx.sd = yy.sd
There can only be one row from ynot where sd matches the value in the current xx.sd, so the subquery only finds one row.
E.g. when updating the row where sd = sysdate + 50 the correlation value xx.sd is sysdate + 50 and there is only one row with that value, so the
row_number() over (partition by null order by sd )
is counting rows from a set of 1 rows, which is why it always gives 1 as the result.
You seem to be expecting the analytic clause to look outside the subquery, but it can't do that.
One way to do what I think you want to do is via a merge:
merge into YNOT dst
using (select rowid rid, row_number() over (partition by null order by sd ) rnum from ynot) src
on ( dst.rowid = src.rid )
when matched then update set id = src.rnum

How to use outer join in Corelated Update?

Hi,
I am using outer join in correlated update comand. But it is not updating the line which is not retrived from the query. Below is the example.
Update model_table a
Set a.model = (Select b.model_name from parts_table b
                    where b.model_id (+) = a.model_id)Check the above query and please let me know whether can user like this or not?
Thanks

Updating the values you want through subqueries is tricky. The correlated update should perform okay if the join columns are indexed but updating the correct rows may take some thought.
You might need to add a WHERE clause to the update to use the subquery to only update the rows when the subquery return value is not null - if this is what you want. Something like
Update model_table a
Set a.model = (Select b.model_name from parts_table b
                    where b.model_id = a.model_id)
where exists (Select b.model_name from parts_table b
                    where b.model_id = a.model_id)Edited by: riedelme on Jan 4, 2010 5:59 AM

Better method for update query

Thanks in advance for any help you can offer on this...
I have two tables:
DETAIL_TABLE with columns: email_address, invalid_format_indicator, source, create_date
SUMM_TABLE with columns: run_date, source, email_address_cnt, invalid_email_address_cnt
Each week I run a job that truncates, then inserts new rows into the DETAIL_TABLE of email addresses that are likely invalid (invalid_format_indicator = 'Y'), and the source system ("source") that created them, as well as the date they were created in our system. Later in the process of that same job, I add new rows into SUMM_TABLE with counts.
So, for data:
DETAIL_TABLE:
email_address|invalid_format_indicator|source|create_date
joe.aol.com|Y|web|2011-03-01
mary@myurl|Y|web|2011-03-05
larry 2yahoo.com|Y|phone|2011-03-06
After the DETAIL_TABLE is refreshed, new rows (14 of them) are inserted into the SUMM_TABLE whereby it creates a new row for each source. What I then want to do is update the 'invalid_email_address_cnt' field by counting the number of rows in DETAIL_TABLE, grouping by source.
Right now, I'm running 14 update queries simultaneously--one for each source.
Data looks like this after the update is complete (bear in mind, it's being updated via 14 separate queries):
SUMM_TABLE
run_date|source|email_address_cnt|invalid_email_address_cnt
2011-03-06|web|25|5
2011-03-06|phone|3|1
2011-03-06|loader|20|4
2011-03-06|source14|5|2
It looks like this BEFORE the update:
run_date|source|email_address_cnt|invalid_email_address_cnt
2011-03-06|web||
2011-03-06|phone||
2011-03-06|loader||
2011-03-06|source14||
I'm currently running this update statement:
Update SUMM_TABLE S
set invalid_email_address_cnt =
(Select count(*)
from DETAIL_TABLE D
where D.source = 'web'
and D.invalid_format_indicator = 'Y')
where S.run_date = sysdate
and S.source = 'web';
I repeat this query 13 more times-- one for each source. Ick...
I'd like to consolidate it to one query. I prefer not using PL/SQL. The tool I'm using doesn't support PL/SQL (It's an open source ETL tool), so if I can do this via straight SQL (Oracle compliant) that would be ideal.
Any help would be greatly appreciated!

I believe you just want a correlated update
Update SUMM_TABLE S
   set invalid_email_address_cnt =
      (Select count(*)
        from DETAIL_TABLE D
       where D.source = s.source
         and D.invalid_format_indicator = 'Y')
where S.run_date = sysdate;I'm not sure, though, about the WHERE clause. Surely you mean TRUNC(sysdate) or you're using a local variable that you used to insert the row into the summary table. Otherwise, if you get unlucky and the clock ticks while your procedure is running, the update may not affect any rows.

How to tune this update statement?

Hello,
I have to solve the following task:
Update every row in table A which has an appropriate row in table B and log what you have done in a log-table.
It is possible that there are more than one fitting rows in table A for a row in table B.
My first approach is looping over the table B and doing an update of table A for every entry in table B.
This works and looks like this:
Table A:
PK number (This is the primary key of this table)
KEY number
Table B:
KEY_OLD number
KEY_NEW number
Log table:
PK number
KEY_OLD number
KEY_NEW number
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;Because the table B can have up to 500.000 entries (and the table A has even more entries) this solution will cause many update-statements.
So I am looking for a solution which has better performance.
My second approach was using an correlated update and looks like this:
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;Now I have only one update statement.
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 get the old value.
Is there a possibility to modify this second approach to get the old value of the KEY before the update to write it in the log-table?
And now I need your help:
What is the best way to get a performant solution for my task?
Every help appreciated.
Regards Hartmut

Below is a script you can run in another testing schema to do the update with logging..... I have created the tables (A and B) with primary key constraints defined...

commit;
----- insert to log
insert into TMP_TAB_LOG_DUB(PK, KEY_OLD, KEY_NEW)
select a.pk
, a.key as key_old
, b.key_new as key_new
from table_a a
join table_b b on a.key = b.key_old;
----- update table_a
update(select a.pk
, a.key as key_old
, b.key_new as key_new
from table_a a
join table_b b on a.key = b.key_old)
set key_old = key_new;

First step is to look for "correlated" into the on-line doc :

Update w/self referencing select?

Hey;
This doesn't seem like it should be too difficult; however, I can't seem to wrap my head around it.
I have a table w/following structure:
city
state
region
Due to the way the table is getting populated, some of the regions are null. Such that:
madison
wisconsin
Midwest
and
milwaukee
wisconsin
<null>
I would like to periodically update the region column with relevent information.
I'm pretty sure I need a look up table and have already generated one:
create table as
(select unique state region
from regions where region is not null);
but, I can't quite seem to grasp the sql to update the regions table from the lookup. Probably my procedural programming mindset getting in the way again.
Can someone provide the needed clue?
Thanks.
Doug O'Leary

Hey;
Thanks for the replies. I see I need to explain how the table's getting populated.
The city/state are geting added via an external source - a script that hits an external site to gather information then pump it into the database. The external site doesn't have any requirement, interest, or info on the region - that's my requirement. A query I'll be writing i the future will hunt up inventory in a region. So far, I've updated a bunch of the regions manually
update regions
set region = 'northwest'
where state i ('xxx','yyy','zzz');
Every time a new city gets added, though, the region is null. Explains why there are some null values and why I can't (at least, not yet) add a foreign key constraint.
Since I do have most of the states and the regions, I should be able to update the states that have null regions with the information from the states that don't.
I'm betting I just made the whole thing a lot murkier, but that explains how I got to where I am.
Thanks for any hints/tips/suggestions.
Doug
//a few seconds later
After i posted this, I saw the correlated update. That's exactly what I was looking for. I was pretty sure it'd be something like that (hence the subject); however, I just can't quite grasp that yet... <sigh> more practice.
Thanks alot for the suggestion. it was perfect.

Hi,
I have the following update statement which runs for over 3 hours and updates 215 million rows, is there anyway I can rewrite it so it performs better?
UPDATE TABLE1 v
SET closs = (SELECT MIN(slloss)
FROM TABLE2 l
WHERE polnum = slpoln
AND      polren = slrenn
AND      polseq = slseqn
AND      vehnum = slvehn
AND      linecvg = sllcvg);
Are you trying to perform a correlated update? If so, you can perform something similar to;
Sample data;
create table t1 as (
   select 1 id, 10 val from dual union all
   select 1 id, 10 val from dual union all
   select 2 id, 10 val from dual union all
   select 2 id, 10 val from dual union all
   select 2 id, 10 val from dual);
Table created
create table t2 as (
   select 1 id, 100 val from dual union all
   select 1 id, 200 val from dual union all
   select 2 id, 500 val from dual union all
   select 2 id, 600 val from dual);
Table createdThe MERGE will update each row based on the maximum for each ID;
merge into t1
using (select id, max(val) max_val
       from t2
       group by id) subq
on (t1.id = subq.id)
when matched then update
    set t1.val = subq.max_val;
Done
select * from t1;
        ID        VAL
         1        200
         1        200
         2        600
         2        600
         2        600If you want all rows updated to the same value then remove the ID grouping from the subquery and from the ON clause.

SSM-AIP 7.0(1) Global Correlation config nightmare!

Thanks, Cisco, for creating a Management nightmare with your "Global Correlation" option in version 7.0...
Lets start with the SSM-AIP-20 Management interface...
We have an OOB Management network, with a single POI into this through a separate PIX515E appliance. Both the ASA5540 AND the SSM-AIP-20 reside on this network.
The first issue was in Routing, since the ASA sees the Management network as "directly attached", and we ROUTE the traffic through the PIX for updates on the SSM module, we had to add translation entries in the PIX515E for the SSM module (10.x.x.x Management, 172.x.x.x translated).
This was not a big issue, but here is where the nightmare begins...
First a note: We have the Management network locked down TIGHT, only a couple of Network Management stations allowed into that network to access these devices.
I enabled Global Correlation in test mode, but it was "failed" every time it tried to update.. Reading other posts, I created ACL and Static NAT in the PIX515E for these IP's:
204.15.82.17 (IP listed in the IME Global Correlation update server)
97.65.135.170 and .137 (from another post in these forums)
207.15.82.17 (IP found in a trace)
Still no updates. Looking in the PIX logs, I found "no translation" entries for the following addresses:
198.133.219.25
209.107.213.40
208.90.57.73
I put these in, and it started updating! FIXED? NOT!
This morning, it was again failing... Looked in the PIX logs again, and found these:
77.67.85.33
77.67.85.9
Entered them, and the SSM is happy again. How long? Who knows?
So, now I have NINE holes in my "secure" network, and who knows when Cisco will change or add new IP addresses to this list.
Cisco, if you are listening - ALL access to/from the Global correlation through a single IP? PLEASE?
(use the one listed in the IME - 204.15.82.17, for the URL "update-manifests.ironport.com")

A few of the addresses belong to Cisco (originally ironport.com addresses from the ironport aquisition) and are used as manifest servers to provide the sensor a list of files to download.
The sensor then downloads those files from Akamai servers. Akamai has a large number of servers across the world. Cisco sends the update to Akamai and they replicate it across their servers. When sensors try to connect to the Akamai server it does a DNS query and by controlling the DNS response it can direct sensors to an Akamai server located nearer to the sensor. This allows for better load balancing, response times, and download speeds.
However, Akamai has a large number of servers (in the thousands I think) world wide, and you can't predict which server your specific sensor will be directed to.
Sensor connections to the cisco servers for the manifest (file list) is on port 443, and usually to update-manifests.ironport.com URLs.
Sensor connections to the Akamai servers for the actual file downloads are on port 80 and usually to updates.ironport.com URLs.
The above is all based on my limited understanding of how the updates work. I may have gotten a few details wrong, but should at least give you a general idea.
I will be working with development to get this better documented in Release Notes and Readme with the next IPS software release.

Need help with update query

I am having a strange problem with an update query I am running. Here are the specifics:
1. I run a script that extracts qualifying rows form a source table (S1), performs some calculation,s and stores the results in a temporary table (T1).
2. The calculations stored in the temporary table (T1) are only for a subset of rows in the source table (S1).
3. The temporary table (T1) uses the same primary key values as the source table (T1).
4. Once the calculations are completed, I want to update a single column on the source table (S1.CalcValue) with the calculated value from the temporary table (T1.CalcValue).
The problem is that I am doing monthly updates so I run month 1, do some verification of the data and then update the source table. Then repeat the process for months 2 through n. When I run the update for the month 2 data, the prior month 1 data for the column is lost. Below is the update script which looks like it should work and only update on the matching keys between the temporary table (T1) and the source table (S1). I was wondering if anyone could let me know what is wrong with this script and why.
I am new to Oracle having worked extensively in SQL Server, so the syntax differences are killing me right now so any help would be appreciated.
Update script:
procedure update_rvu AS
BEGIN
--update the test.RVU table
update test.RVU S1
set S1.CalcRVU = ( select
T1.CalcRVU
from
TMP_RVU T1
where
S1.GroupId = T1.GroupId
and
S1.PatientId = T1.PatientId
and
S1.InvoiceId = T1.InvoiceId
and
S1.TransId = T1.TransId
commit;
END update_rvu;

Most likely you want a WHERE clause in your update portion ... something like
update test.RVU S1
set S1.CalcRVU = ( select
T1.CalcRVU
from
TMP_RVU T1
where
S1.GroupId = T1.GroupId
and
S1.PatientId = T1.PatientId
and
S1.InvoiceId = T1.InvoiceId
and
S1.TransId = T1.TransId
where exists
   select null
   from tmp_rvu t11
   where S1.GroupId = T11.GroupId
   and    S1.PatientId = T11.PatientId
   and    S1.InvoiceId = T11.InvoiceId
   and    S1.TransId = T11.TransId
)You can also look into using the MERGE command (if you're on version 10 or better you can perform update only operations with it). I personally find it more 'friendly' than correlated updates a lot of the time.

Multiple Row Update From Similar Table

I am attempting to update a table based on similar table if the Entry_Type is D and they have the same log_numbers. I have created queries to show me the results I want but am having some difficulities getting the update to happen. I am getting a single-row subquery returns more than one row error, but I would like to update all necessary rows.
Here is my sql...
UPDATE V.MASTER
SET (MODIFIED_BY, ENTRY_TYPE) = (
     SELECT MODIFIED_BY, ENTRY_TYPE
     FROM J.BACK)
     WHERE LOG_NUMBER IN
     (SELECT LOG_NUMBER FROM V.MASTER
     WHERE ENTRY_TYPE <> 'D' AND LOG_NUMBER = ANY
               (SELECT LOG_NUMBER FROM J.BACK
               WHERE ENTRY_TYPE = 'D'))
I would appreciate any assistance! Thanks!

You can also use correlated update. This one is from AskTom (http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1197999096334)
if you have the proper primary keys to assure uniqueness on S and C, this does it (i have the keys
noted in the creates)
ops$tkyte@ORA920> create table pgp_person

3 update_by varchar2(10),
4 update_date date,
5 load_timestamp date,
6 person_num int );
