Would this query be faster in Oracle 10?
I'm running 2 queries on Oracle 8i:
Query 1:
select count(Member_ID) from
select Member_ID, c2, c3, ... c100 from T1
union
select Member_ID, c2, c3, ... c100 from T2
union
union
select Member_ID, c2, c3, ... c100 from T10
Query2:
select count(Member_ID) from
select Member_ID from T1
union
select Member_ID from T2
union
union
select Member_ID from T10
The columns c2 to c100 in Query 1 involve a lot of cast statements. Query 1 takes about 81 seconds and Query 2 takes only about 1/4 second – which is a big difference. These 2 queries are equivalent in terms of what the would return. The reason I am doing Query 1 is because I want the inner query to be a view.
My question is does anyone know if Oracle 10 would be smart enough to 'forget' about columns c2 to c100 in Query 1 as they are not needed in Query 1? Could the execution times of the 2 queries be similar in Oracle 10?
Please don't ask me to see the whole queries as they too big and beside the point.
Denis,
The answer to your question is that Oracle is smart
enough to know it simply cannot 'forget' columns c2
until c100. The fact that in your case both the
queries return the same result, does not mean the two
are semantically equivalent.
In query 1 you use a union operator, meaning it has
to do a SORT UNIQUE step. In other words: only when
the rows (member_ID,c2,c3,...,c100) are completely
identical they will be merged. In query 2 the rows
only get merged when member_ID's are identical.
Regards,
Rob.Thanks for your help! I didn't think about that! In this case the Member_ID is unique (but I didn't say that from the outset). I'm going to try this thing over using Union All instead of Union. If that doesn't help me - I may write back with an update on the post...

How to make this query go faster
Hi ,
I have the following query :
select a.* from
tbl1 a , tbl2 b
where a.id = b.id
substr(b.id , 3, 2) <> 'XX'
and b.date1 is not null
and b.date1 >= sysdate - 90 ;
tbl1 - 21 million rows
tbl2 - 2 millions
i specify this hints /*+ INDEX(idxa_1 , idxa_2) INDEX(ixdb_1)
where idxa_1 --> b.lotid
idxa_2 --> b.date1
idxb_1 --> a.lotid
IF i DO NOT include b.date1 is not null and b.date1 >= sysdate - 90 ,
from explain plan i could see it using a FAST FULL SCAN which really returns very fast
HOWEVER if i include b.date1 is not null and b.date1 >= sysdate - 90
, from explain plain it uses row index and then there's a range scan and its slow
how can i improve the performance of this query ?
pls advise
tks & rdgsDon't create the temporary table.
Create a function based index on table two
substr(id , 3, 2)Make sure you have gathered statistics on the tables.
Remove the hint.
select a.* from
tbl1 a , tbl2 b
where a.id = b.id
and substr(b.id , 3, 2) <> 'XX'
and b.date1 >= sysdate - 90;If you still have performance problems, post the formatted explain plan from sqlplus.
Read the Performance Tuning Guide.
Unfortunately this is not urs advice. -
Why would this query return three rows?
select pc.tour_id,
pcp.project_id,
pc.contr_num,
pc.current_contr_status,
pc.current_contr_substat
from p_contract_lead pcl
left join p_contract pc on pc.contr_num = '2385108'--pcl.contr_num
left join p_contract_purchase pcp on pcp.contr_num ='2385108'-- pc.contr_num
where pcl.lead_id = '179772978'
in this query it returns me 3 rows,
in p_contract there is only 1 row with contr_num = '2385108'
and p_contract_purchase also has 1 row with contr_num = '2385108'
in p_contract_lead the lead_id = '179772978' has 3 records but they dont have contr_num=2385108
im just wondering why is giving me these results?
shouldnt it give me zero results since the pcl.lead_id = '179772978' does not equal contr_num=2385108?
i have version 12.0.0.6, maybe is the way i dont understand the left join works, or could be something else?
sorry for not creating a example , because i really dont know how.
thanks for your helpHi,
FROM l
LEFT OUTER JOIN r ON ...
means include all rows from l whether or not they have a match in r.
If you have 3 rows in l, then there will always be at least 3 rows in the result set, regardless of what's in r (if anything).

What you just described is basically how an inner join works.
In this case, it doesn't matter in the least whether pcl.lead_id equals anything in pc or not. The join condition between pcl and pc is
pc.contr_num = '2385108'
That is, a row from pcl will match a row in pc if (and only if) pc.contr_num='2385108'. The join condition makes no mention of pcl.lead_id (or any other column in pcl, for that matter), so what's in pcl.lead_id (or any other column of pcl) doesn't play any role in deciding if rows match.
sorry for not creating a example , because i really dont know how.
Post CREATE TABLE statements for all 3 tables. You only need to include the columns that are used in this query.
Post 1 INSERT statement for p_contract, with contr_num = '2385108'. It wouldn't hurt to post an additional row that you know shouldn't appear in the results.
Post 1 INSERT statement for p_contract_purchase, also with contr_num = '2385108'. Again, it wouldn't hurt to post a 2nd row that does not meet the join condition.
Post 3 INSERT statements p_contract_lead with lead_id = '179772978' , but NOT contr_num='2385108'. Again, having another row with a different lead_id would make a better example. -

Why would this query return an error that mentions an entirely different database being offline?
Trying to get a list of fragmented indexes based on a database name. However,
SELECT COUNT(*) AS TableFragOver80PctCount
FROM sys.dm_db_index_physical_stats (null, null, null, null, null )as ts
INNER JOIN sys.tables t on t.[object_id] = ts.[object_id]
INNER JOIN sys.indexes i on i.[object_id] = ts.[object_id]
INNER JOIN sys.databases db ON ts.database_id = db.database_id
WHERE db.name = 'MY DB NAME'
AND ts.avg_fragmentation_in_percent > 80.00
The error I get back
Msg 942, Level 14, State 4, Line 1
Database 'VERY DIFFERENT DB' cannot be opened because it is offline.
I know there is a database on this server that is offline, actually 2 or 3, but not the one Im trying to get information about. What could cause the above query to have trouble getting index info that is caused by an entirely different database being
offline?FROM sys.dm_db_index_physical_stats (null, null, null, null, null )as ts
See MSDN sys.dm_db_index_physical_stats
; the first parameter is the database id; if you pass NULL as here, then all databases will be scanned, also your offline one.

Need Help..But how can i frind the query is run by user is from oracle forms or from oracle reports.
How can i get the name of form or report from where user is running.did you read the document about v$session attached in the other post?

Edited by: 981527 on Feb 1, 2013 4:50 AMI am taking a guess that 'Dept' is where the employee works, so that will be the column 'NAME' in the table HR_ALL_ORGANIZATION_UNITS; you will need to join with this table on the assignment's organization_id value
Edited to add: Whilst you're testing this, you might want to consider removing the table PAY_ELEMENT_ENTRIES_F from the table list, otherwise you can look forward to potentially large cartesian product of returned rows!

Is there a faster form of this query?
I received a table of corrections that have to be 'propagated' to a master table, i.e. the corrections table is composed of a few columns and every value of every column of every row must be used to update the corresponding row-column in the master table. Both tables have id columns that can be used to match rows from the two. The query I was given to do this was:
update master a
set a.calculated_error = ( select calculated_error from corrections b where b.id = a.id ),
... additional columns to update follow with the same syntax.
The columns being updated are not indexed in either table.
The query takes a very long time to run. I suppose I can see why, lots of queries on columns that are not indexed so each query involves a table scan.
Is there a faster form of this query?
Thanks,
-=bIn additon to Herald's suggestion, assuming he is correct in his assumption that corrections is small in relation to master, I might also consider updating all of the columns in one shot. something along the lines of:
update master a
set (a.calculated_error, a.first_add, a.second_add) = (select calculated_error, first_add, second_add
from corrections b where b.id = a.id )
WHERE a.id in (SELECT id from corrections)Alternatively, if corrections.id is unique, I might also try creating a unique index on it and using an updateable join view like:
UPDATE (SELECT a.calculated_error, a.first_add, b.second_add,
b.calculated_error new_calc, b.first_add new_first,
b.second_add new_second
FROM master a, corrections b
WHERE a.id = b.id)
SET calculated_error = new_calc,
first_add = new_first,
second_add = new_secondIf you need to deal with NULLs in corrections, then use something like:
SET first_add = NVL(new_first, first_add)John -

I have used following queries in my 9 screen interactive report.Output/result is perfect but performance became damn slow.
I have used........(note : T2 is internal table)

How do I speed up this query by ignoring computers off the network faster?
Good afternoon,
I am running the below script to query the entire domain for local admins. Could anyone reccomend a way to speed this up by more quickly skipping computers that aren't on the network? Currently, every time it reaches a computer that is not on the network
it hangs for up to 20 seconds (computers on the network return the data in less than a second). If I could decrease the ping time-out time, I could speed up this query tenfold.
Script pasted below - Thank you!!!

Hi JRV,
Thank you for your help so far! When I ran the above version, it seemed to be going fine but it stopped at a certain point saying the script was "successful", but it only queried 148 computers. I should note that it is also the same 148 computers each time
I run it. No errors, it just stops and says successful. Any ideas?
TY! -
I am new to oracle, plz..anybody can explain this query step by step....plz
Select distinct(a.esal) from employee1 a where &N = (select count(distinct(b.esal)) from employee1 b where a.esal<=b.esal);
this is the query to find Nth largest & Nth smallest value from the table employee1....but, i am unable to understand how this query works ....plz..anybody can explain this query step by step with example....plzHi,
Welcome to the forum!
The first step in understanding any code is to format it so you can easily see what is a sub-query, what the major clauses of each sub-query are, and things like that.
For example:
Select distinct (a.esal)
from employee1 a
where &N = ( select count (distinct (b.esal))
from employee1 b
where a.esal <= b.esal
);The only thing I have added to the code you posted was whitespace: newlines, tabs and spaces.
Now it's easy to see that you're doing a query with a scalar sub-query in the WHERE clause.
It usually makes sense to read complicated queries from the inside out, that is, start with the deepest nested sub-query.
In this example, that means:
select count (distinct (b.esal))
from employee1 b
where a.esal <= b.esalWhat does this query do? Unfortunately, it references something (b.esal) from the super-query, so you can't run it by itself, to see what it does. Let's replace that reference with some hard-coded value, just for now, and run it:
select count (distinct (b.esal))
from employee1 b
--where a.esal <= b.esal -- This is the original WHERE clause
where a.esal <= 1000 -- For testing only
;Experiment with this for a while, and compare it to the values in the employee1 table (or a small test table that resembles employee1). Try different numbers in place of 1000.
You'll see that the query is counting how many different salaries are lower than, or equal to, a given salary (1000 in the example above).
When you understand the sub-query, look at the original query again.
It is testing to see if exactly &N different esals are lower than or equal to the esal on each row, and displaying that esal if it is. (&N is a substitution variable. If you haven't already defined a value for it, SQL*Plus will ask you for a value when you run the query.)
In other words, it is finding the N-th lowest value of esal. -
Hi,
I'm using below query in procedure.It's taking more more time can some one help to tune this query or advice to rewrite the query.

7 - filter(TO_NUMBER("C"."RESTART_FLAG")=0) It means that Oracle had to do a conversion for you since you aren't using the proper data type in your query.
That would mean IF there is an index on that column, it won't be useable... -
Like % in a query running on an Oracle Apps table with 8 million records
I am running the below query. As per the explain plan it is using the index on organization_id and inventory_item_id.
select segment1 from mtl_system_items where organization_id = 100 and inventory_item_id like '123456%'
It takes about 15 min to run this query which is a long time as this query returns values to the frontend created in asp. The webpage would time out by the time this query completes running. do you have any suggestions on how to run this query faster?It is an oracle apps table. below is the structure -
