Im looking for a query which returns the batch for which all the child should either be in 'A_STATUS','B_STATUS' or 'C_STATUS'. In this query im expecting a query which returns batch 2,3 and 4.
create table batch (batchid number);
insert into batch values(1);
insert into batch values(2);
insert into batch values(3);
insert into batch values(4);
[Code]...
I need to fech parent records only when no child record with status 'N' exists. There are only two possible values for status column of child table 'Y' / 'N'.
Below are table structures and insert statements for data.
CREATE TABLE MASTER
(
COL1 NUMBER,
[Code]....
COMMIT;Query I framed is below
select * from master where exists (select null from child where child.col2 = master.col1
group by child.col2 having count(distinct col3) =1 )
Output in above case would be 3 as for 1 there's one record with status as 'N' and for 2 there's no child record. I am on 10g.
We are having a major issues with the batch run. we are using oracle 11g db. We run the scripts to populate the tables and then call scripts to run the extractions. The issue here each time we run the sql it takes so much inconsistent time.We have created index and run the db stats then run the extractions.The sql sometimes takes 10 minutes or sometimes takes hours to run? This is major show stopper of the project.
View 3 Replies View RelatedJust wanted to pose a question Can a (Unique and Not nullable)Alternate key of the parent table be part of child Table in an Identifying relationship i.e part of primary key of a child table????
Is there a rule that a primary keys of a parent table can be used to build a identifying relationship with its child?
I've the following data and i need the parent and leaf most child,including their id's
Create table par_chld (id,p_id,c_id) as
(select 1,900,501 from dual union all
select 2,900,502 from dual union all
select 3,900,503 from dual union all
select 4,100,900 from dual union all
select 5,200,900 from dual union all
select 6,300,400 from dual union all
select 7,101,500 from dual union all
select 8,102,500 from dual union all
select 9,103,500 from dual union all
select 10,201,600 from dual union all
select 11,201,601 from dual union all
select 12,201,602 from dual )
In the above data
p_id =100 has c_id 900 , and this 900 acts as a parent which has child 501 , 502 ,503
And the output should be in the following format , Where i don't need the middle level data. I need parent and its leaf child along with the id's of parent and child
Expected output
id_p p_id id_c c_id
4 100 1 501
4 100 2 502
4 100 3 503
5 200 1 501
5 200 2 502
5 200 3 503
6 300 6 400
7 101 7 500
8 102 8 500
9 103 9 500
10 201 10 600
11 201 11 601
12 201 12 602
I tried the following query where i got the p_id,id_c,c_id columns , but unable to get the column id_p
select connect_by_root p_id p_id ,id id_c,c_id
from par_chld
where connect_by_isleaf =1
start with p_id not in (select c_id
from par_chld
where c_id is not null)
connect by nocycle p_id =prior c_id
getting the id_p column as expected above.
I have a requirement to get the data in "SQL" directly and should not use plsql/ can't redirect the output to a .sql file. I have a master table Main_tab which does have all "child table" names.
I want to build a query such that it will give all the data from child tables.
create table main_tab ( tab_name varchar(10));
insert into main_tab values ('one');
insert into main_tab values ('two');
insert into main_tab values ('three');
create table one ( a char);
insert into one values ('a')
create table two ( b char);
insert into two values ('b')
create table three ( c char);
insert into three values ('c');
Now I have got the query to combine all the table data using
select decode (rownum,1,'','union all ') || 'select * from ' || tab_name example from main_tab
but I am expecting the output to get as
a
b
c
which is the data from tables one,two and three respectively.
I don't want to save the above select data in to .sql and then execute it , instead I want to run it on "fly" in SQL itself. Is there such a possibility to do so?
way to achieve the below logic.
SQL to pick up parent child relationship within same table with a certain logic.
Example:
mod_product_numberProduct_Hierarchy
H555888 PH05678
H888987 H555888
H8889 H555888
[code]...
Example: I expect the rows with H8889,H9955 & P6666 & P5555 to be sub-category values value for product hierarchy H555888.
If there are rows with H8888987 as Product_hierarchy, we will pull up those rows too for product hierarchy H555888. The extra condition is we drill down only on 7 character mod_prod_number not on 5 character mod_prod_number. We pull out all sub category mod_prod_number for all distinct Product hierarchy.
I have one requirment like below
Table1 have records like below
parent childflag
null.....A......Y
A........B......Y
B........C
C........D
D........E......Y
I want it should be like
parent child flag
null......A.....Y
A.........B.....Y
B.........E.....Y
I want to replace 'D' (parent of 'E') with any of the upper level which has Flag 'Y' (first level parent which satisfy falg 'Y')

View 9 Replies View RelatedI have a DB that has one parent table with many child tables. I would like to delete all records(child - parent) based upon a particular "net_id". I have three versions that "seem" to work BUT I'd like to use "version2" because I want to go to the parent one time(for the parent delete I just made it simple for me) only and be able to delete the child record(s) from the child table(s).

I'm trying to write a generic function for un-nesting child nodes where nesting is deemed unnecessary. Typically when the element only has one child element.
For example, given the following source....
<ROOT>
<ITEM>
<DESCRIPTION>TEST1</DESCRIPTION>
</ITEM>
<ITEM>
<DESCRIPTION>TEST2</DESCRIPTION>
</ITEM>
</ROOT>I actually want.....
<ROOT>
<DESCRIPTION>TEST1</DESCRIPTION>
<DESCRIPTION>TEST2</DESCRIPTION>
</ROOT>
because we think ITEM isn't really required before we deliver XML data.I've been trying to achieve this with a function, where I pass in the XPath to the node I want flattening, something like
function UnNest(pXMLData XMLType, pXPath varchar2) return XMLType...Called like the following...
declare
begin
vXMLData := UnNest(SomeXMLData, '/ROOT/ITEM')
end;I tried using XQuery Update (11gR2), as follows,

My destination platform is 11gR2 64 bit but going forward I may need a solution for 10gR2 too. Perhaps there is another way without using XQuery Update?
The manual work around on populating child tables for testing purpose are taking long time and its very painful work. So I am trying for a tool that takes parent table name and child table name as input and produce insert statements for child table with foreign keys as output.
View 5 Replies View RelatedI've a table TXN1 transaction and has FKs to 3 different tables Account, customer, country and currency. ALL FKs are indexed (bitmap). I am updating TXN1 of amount column about 10,000 rows. (SID 1) As expected, it has taken lock type 3 SX on TXN1. But it has taken on lock type 4 (share) on Account, customer and country. Committing every 10k rows.
At the same time sid 2 is inserting into another TXN2 table which has FK to the same dimensions account, customer and currency. Only FK on ac_id is bitmap indexed. The inserts have taken SX lock(type 3) on tXN2 table (expected). But it is trying to take SX type 3 lock on account, customer, currency tables. typ3 lock taken on CCY but waiting on CST. But It is blocked by sid 1. It has resulted into Enque-TM contention and resulted into anywhere 60-300 secs wait time..
I understand update/delete in parent table results into locking of SX of child tables and need the FKs to be indexed to avoid etc.
1. Why is SID1 taking shared lock on the parent tables Account,customer,country and currency tables? The update statement is not updating any of those FK columns nor referring them in where clause(if it matters!). Is it to ensure that the parent rows are not deleted?
2. Why is SID2 taking SX lock on the dimension tables? Why is it not taking RS lock type 2 on parent rows? Why is SID1 taking shared lock type 4, but not 2?
I have a table which has plenty of rows. In production, I would estimate it to be from 30 millions to 300 millions. I need to update on column (flag) in all the rows (created before certain date).Now saying just:
UPDATE MyTable SET flag = 3 WHERE created < to_date('2010-10-08 23:59:59', 'YY-MM-DD HH24:MI:SS');
COMMIT;
Does not seem like a good idea - the commit-buffer would become too big.I will write a PL/SQL script for this. The question is, whether I should:
a) Update each row separately, and commit after every 10000 rows. ( WHERE RowId = [rowId] )
b) Update 10000 rows with set of dates ( WHERE rowId > [some_row_id] AND RowId < [some_row_id_2]
In the latter example the some_row_ids would naturally be fetched. The rowIds come from sequence. So which one would be more effective?I am not too familiar with PL/SQL or Oracle for that matter.
I'm having an issue with stale optimizer statistics for some SQLs that are run in a batch process. The problem is that the process runs many times during the day - sometimes 20 to 30 times. And each time, the tables are updated, i.e. rows are inserted or deleted, etc.
So eventually the optimizer statistics for those tables become stale and the performance of the SQLs start to slow down (a lot). How best to gather the optimizer stats on the tables so they don't become stale when the batch process runs each time? The problem is that I also can't add/modify the code in the batch process because it is delivered by the vendor as is.
I would the query to do the following:
1. Make the jobname distinct, because it keeps giving me multiple entries for each jobname
2. Add the the start_time of SOD_start_data9_UAT1 to end_time fodba_MUAT1 to get the combined duration
3. CONCAT jobnames SOD_start_data9_UAT1 and end_time fodba_MUAT1
4. Generate the last seven days batch run times
5. Generate a report into .csv format and email out

We have a critical application batch that runs daily and had a 7.5 hr window after which the application needs to come online. During the peak batch times the truncates are running very slow leading to slow down of the batch jobs quite considerably due to which the batch is going beyond the window.
Technical details:
Database version: 11.2.0.2
OS: HP-UX 11.31
The wait events that show up when the truncates are running are local write wait
enq: RO fast object reuse
enq: CR block range reuse ckpt
db file parallel write
The ASH reports show that the top sessions are those executing DMLs(insert, merge, update) and DDLs(Create/alter index & truncate). In addition to this it also shows that the blocking sessions are background wait events: CKPT and DBWR. Changes to DB configuration done with respect to addressing these issues are:
1) We have increased the DBWR processes to 2
2) Reduced the buffer cache size to 20G(from the original 30G)
3) Flushing the buffer cache before the batch begins in order to reduce the load on DBWR during the batch peak time
4) Set the parameter filessytem_io to SETALL(from none)
5) Tuned the EVA(SAN storage) to improve its performance - by distributing the loads evenly between the controllers, reducing the IO transfer block size, etc
6) Suggested using the reuse storage clause to improve truncate performance.
All of these have worked bring a semblance of control but the fact remains that the batch is generating more jobs(hence increasing data volume) over time due to it being the peak season. This causes an inevitable increase in the number of sessions all running DMLs and DDLs which are IO intensive operations.
Suggestions pending from our end:
1) Increase DBWR beyond 2. For this we need a H/W upgrade since we have maxed out the maximum number of DBWR that can be configured
2) Implementing asynchronous IO for DBWR which on HP-UX requires moving to raw disks. Hence have suggested using ASM.
3) Tuning the application to either reduce the IO generated or redistribute the jobs such that those with maximum loads don't run together
instead of truncating tables, can we rename the tables and delete them later . will this improve performance ?
I'm working on a Self assessment project regarding our tax returns. Currently, this is how it works - a return lodged generates a return number, but is batched later. In the change proposed, they want the same process whereby a return is generated still, but at a count of 10 returns generated on the same screen, a batch is to be created and these 10 returns will have to be added to that batch. We are on Oracle 10G and work with Forms, Reports 10G and TOAD/SQL Plus as tools so I was thinking of changing it on Post-Query but suggestions are to add on to System Parameter table.
