The TKPROF detail will follow after the query.

Hi,
it looks like your problem stems from the wrong choice of the driving table:
4615 4615 4615 NESTED LOOPS (cr=123763 pr=96435 pw=0 time=750949543 us)
4615 4615 4615 TABLE ACCESS BY INDEX ROWID RA_CUSTOMER_TRX_ALL (cr=114531 pr=96435 pw=0 time=750675597 us)
329687 329687 329687 INDEX RANGE SCAN RA_CUSTOMER_TRX_N17 (cr=6232 pr=6046 pw=0 time=31982795 us)(object id 4788) 4615 4615 4615 TABLE ACCESS BY INDEX ROWID RA_CUST_TRX_TYPES_ALL (cr=9232 pr=0 pw=0 time=239450 us)
4615 4615 4615 INDEX UNIQUE SCAN RA_CUST_TRX_TYPES_U1 (cr=4617 pr=0 pw=0 time=160139 us)(object id 55731)
4615 4615 4615 TABLE ACCESS BY INDEX ROWID FND_LOOKUP_VALUES (cr=13847 pr=0 pw=0 time=180337 us)Here, you are spending 750 seconds retriveing 329k rows, 98% of which are rejected on the next step. And the reason this is happening is because the optimizer underestimates the cardinatlity of this step by a factor of x50 (6.2k estimated, 329k actual value). Find out why this is happening or post relevant diagnostic information here (predicates, columns stats etc.), and fix this -- this should make your query twice as fast.
The second half is coming from the SORT UNIQUE step. This looks weird: why on Earth it would take over 800 seconds to sort 34 rows?! Maybe there is something in the plan that I'm missing -- it's really hard to read because it's not formatted. Please obtain a plan with rowsource stats using dbms_xplan.display_cursor and post it here (google dbms_xplan.display_cursor allstats last if not sure how to do that).
Best regards,
Nikolay

How can i do SQl QUERY TUNING in Oracle 9i Database
Hello,
How can i do SQl QUERY TUNING in Oracle 9i Database You can start through reviewing the Performance Tuning Guide;

Good Luck!

Hello,
My question is: I would like to do more complex sql query ( i need to use GROUP BY, HAVING, ORDER BY). Is possible do it with CMP entity bean, or i have to use BMP entity bean or Session bean? Query return about 20-30 items. Can you recommend some design pattern for this situation?
Thanks in advance

HI.
can somebody post me any links for ebooks on SQL Query tuning techniques for either 10g or 11g.
Tuning SQL Queries is something I would like to build my expertise on..
There may be a lot of advisors like SQL Query Advisor, Access Advisor and so on...but nothing like tuning your queries manually to maximum optimization.
Kindly help me in this !!Check Oracle docs http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/toc.htm
But you should really also be checking:
http://www.asktom.oracle.com
http://tkyte.blogspot.com
AND all other blogs he referres to ( like Jonathan Lewis' site and blog ) you'll find many interesting articles over there, from 'the real world', regarding performance and tuning.

Complex SQL Query in BPEL DB Adapter
Hi,
Is it possbile to write a complex query in BPEL DB Adapter using "Custom SQL Query"?
I would like to write an IF ELSE condition in the DB Adapter similar what is given below..
IF((SELECT COUNT(*) FROM F5898001 WHERE CT58SRCNME = 'CA_TEST' AND CTJOBNAME = '12345' AND CTEDBT = 'EDBT' AND CTEDSP = 'B') < 1)
BEGIN
insert into f5898001 (CTJOBNAME,CTEDSP,CTEDBT,CT58SRCNME) VALUES (#jobname, #edsp, #edbt, #srcnme)
END.In a single pass no.
You could use a DB link to perform select and return result to BPEL process variable. Put a switch decision depending on result in variable that calls a DB Adapter to perform the insert.
Wouldn't be in a single transaction and not very elegant, but might be a way round. -
SQLEception using Complex SQL Query with Java Studio Creator2 Build(060120)
I am evaluating Java Studio Creator2 for a WEB base application project that will be making SQL queries to an Oracle Database but I have stumble into a problem using complex SQL queries.
I am getting an SQLException "org.apache.jasper.JasperException: java.lang.RuntimeException: java.sql.SQLException: [sunm][Oracle JDBC Driver][Oracle]ORA-00923: FROM keyword not found where expected". I looks like it cut my sql.
The SQL that I am trying to execute is
Select part_name
from table1, table2
where table1.part_nbr = table2.part_nbr
and table2.row_add_dt = (select max(table3.row_add_dt)
from table3
where table3.ser_part_id =table2.ser_part_id)
This is a valid query that it is using 2 different selects to get a part number.
If posible, point me to the best solution were I will be able to make complex SQL queries like the one above and bigger.
Is there any way that I can read an SQL query file instead of inserting the SQL query string into the setCommand()?I have read that document looking for some anwsers on how to make this kind of query. If I try the query that I have above in the query editor ,the query editor will cut off from the last select that is between ().
I beleave, there is a work around using the inner joint or outter join command. I will try them to see If I get the corrent result. If not, then I have to keep on asking for possible solutions.
Anyway, someone in the Creator Team should take a note in adding something like a special criteria in the Add Query Criteria Box for cases like the one I have. The special criteria will be like using another select/from/where to get some result that will be compare.
Girish, Are you in the Sun Creator Team? -

Obtain rows from a complex sql query
Hi to all, please somebody who can help me, my scenario is as next:
One table like next
Reservation (table)
Boat (string)
reservation (date)
class (string)
room1_cod (int)
room1 (int)
room2_cod (int)
room2 (int)
room3_cod (int)
room3 (int)
In room(x)_cod , I am saving a client code, in the room(x) , I am saving the price of the room for that client.
example:
LUSITANIA, 2014-3-1, MEDIUM, 0, 0, 145, 345, 0, 0 = client 145 ocupied room 2 paying $345
LUSITANIA, 2014-2-1, MEDIUM, 145, 345, 0, 0, 0, 0 = client 145 ocupied room 1 paying $345
LUSITANIA, 2014-1-1, MEDIUM, 0, 0, 0, 0, 145, 345 = client 145 ocupied room 3 paying $345
how would like to make an sql query for filter :
(Boat, reservation, class... with a reservation start date and finish date and with an specific "client code" find and filter this code into room1_cod , room2_cod and room3_cod .... and maybe do a temporarly table with rows containing (Boat, Reservation,
Class, "client_code" , "client_pay" )
Resulting LIKE:
LUSITANIA, 2014-3-1, MEDIUM, 145, 345
LUSITANIA, 2014-2-1, MEDIUM, 145, 345
LUSITANIA, 2014-1-1, MEDIUM, 145, 345
Please I need your guidance. TKSPlease take a look
SELECT Boat, reservation, class,
case
when room1_cod>0 then 1
when room2_cod>0 then 2
when room3_cod>0 then 3
end as Room,
case
when room1_cod>0 then room1_cod
when room2_cod>0 then room2_cod
when room3_cod>0 then room3_cod
end as client_code,

when room2>0 then room2
when room3>0 then room3
end as client_pay

I am trying to take a complex query that I was running inside of C# code and turn it into a stored proc so that it performs much better. I was doing quite a bit of looping in C# code because I am most familiar with that but I know it ain't the best way to do things. Basically my query does the following:
-Query a table to get a set of table names
-loop over that set of table names to query another table to get some info
-use that info to query another table to find out if there are any results
-if there are results add those to a table to be returned to the caller
The issue I am having is that I don't know how to build the return table so I can pass it back to the calling code. All i need to know is the names of the tables that had at least one hit in my big query.
I am kind of new to this so I may have some things in here that are completely bizarre. I won't be offended if you rip it apart. I know that my out SYS_REFCURSOR will not work as is. The part that says 'SELECT OBJECTID really needs to be telling me the name of the table and not OBJECTID. I want to jam all these table names into a resultset which would really just be a temp table that I create with one field (TableName).
I know it's a lot to ask but if anyone can look at any part of this and give me suggestions I would greatly appreciate it. I'm struggling slowly through PL/SQL trying not to do dumb things when there are easier ways. There is probably a way for me to get rid of this loop but I think I need the dynamic part because I am querying different tables. Thank you very much

Check out this link (try to ignore the original question) and see how the third post shows you how to use dyanmic sql using the 'USING' construct.

Hi all,
I had posted a thread named : SQL Tuning - Author name Nnirmalkumar.
But i didnt get any reply on it. Can anyone help me out .
Thanks in advance.Hi Rob Schenk & sivamurugesh
As per you asked following is the thread which i have posted. Please do have a look.
The query is inside the procedure its a dynamic query thats y there would be lots of sub-queries which canot be put in a single sub-query.
SQL TUNNING
Performance Issue
The first thread conists of the procedure with the query.
Thanks in advance. -
Sql Query Tuning. Please help me to tune this query
Hi All ,
I have this problematic Sql . It is taking huge time to execute. It contains a view CIDV, which i think is the bottleneck.
I have pasted the query below. I will be pasting TKPROF and explain plan for the same. Please advice me to tune this query.

A query run by the 'tom' user who searches on (xyz crieteria) takes less than 5 seconds.
However, when the user 'greg' ruuns the same query, it take > 14 minutes to execute for same xyz crieteria.
Note:both are application users and internally use DOCD database user.Both are using same SQL Explain plan but diffrence is disk read in case of long running query.
my question is if both queries are same and using same explain plan and returning same rows why there is disk read???? and such huge diffrence in execution time...Below is the tkprof output for both the queries.

In the future, when posting items to the forum where spacing is critical to proper understanding, please use the { code } tags (without spaces) to retain the spacing.
It appears that there is more to the story than what has been reported. It is good that you used tkprof, as it shows that there is more to the story. Taking a look at the two executions, the tkprof output shows that the first (quick) execution completed in 0.19 seconds, while the second (slow) execution completed in 1.21 seconds, even with th 2,391 blocks read from disk. My first question, if I were in the same situation, would be what would cause the first execution time to jump from 0.19 seconds to 5 seconds, and the second execution to jump from 1.21 seconds to 840 seconds (14 minutes)?
In both cases, there is a library cache miss on both the parse and the execute calls - there may be some significance to this.
In both cases, there were 167 fetch calls to return 1,002 rows, meaning that on average 6 rows were returned on each fetch.
Let's assume that 'tom', whose query executed quickly, was connected to the database over a T1 connection with a 20ms (0.02 second) ping time. For siimplicity in calculation, assume that there were 170 round trips between the server and the client. The network communication between the client and the server would require at least 3.4 seconds, for a total time to send the query and retrieve the results of about 3.6 seconds. This is a little short of 5 seconds which you reported.
Let's assume that 'greg', whose query executed slowly, was connected to the database over a satellite connection with a 2000ms (2 second) ping time. With the same number of round trips, the network communication would require about 340 seconds, for a total time to send the query and retrieve the results of about 341.21 seconds (5.7 minutes), about 8 minutes short of the target 14 minutes.
Was this the only query executed by the clients, or were there multiple queries?
Were the client computers on the same network segment?
Did you gather a 10046 trace at level 8 or 12 for the sessions? If so, manually review the wait events in the trace files to see if it is possible to determine what was happening during the 14 minutes. Guessing can be fun, but sometimes you come up 8 minutes short by guessing alone.

Hi,
I was wondering if I could have some help with the query I have below for this general data set, please? I need to do it in a single SQL statement. We're currently running Oracle 10g. The piece I'm struggling with is identifying that the person has all the items in a collection and to include the collection in the resulting collection of items.
persons_items
person item
Ted cup
Ted saucer
Ted plate
Ted fork
Alice book
Alice thimble
Alice knife
Alice cup
Joe cup
Joe saucer
Joe plate
Joe knife
Joe fork
Joe spoon
Jessica spatula
Jessica dish
collections
collection_name item
crockery cup
crockery saucer
crockery plate
cutlery knife
cutlery fork
cutlery spoon
Query:
What single items and collections does Ted have? fork, crockery
What single items and collections does Alice have? book, thimble, knife, cup
What single items and collections does Joe have? crockery, cutlery
What single items and collections does Jessica have? spatula, dish
Thanks in advance.

Continuation-Please help with a complex sql query
Hi all,
Thanks a lot for your suggestions and inputs in the last thread of this post.
With the help of your suggested approach,i went ahead and was able to get some more data in the format as needed..I worked on gradually adding one table after another exactly as the data is required stepwise.But,still I am facing issues with displaying them.
there are many issues I am not able to do and would appreciate if you please have a look at my latest modified SELECT given below and help me writing it to get the display as needed.
Below,is the attempted query i tried out using your inputs.But,am stuck and need your help in writing it.
**Here,there is 1 ->MANY lines for the t_objective_id--->This has many learning_record_ids which i want to group by the unique objective_id.
Also,prior to that,there is a tplan_id---->which has MANY t_objective_id's

If we see the outer SELECT ---then one of the main issues is for EACH t_objective_id----->There are n learning_record_ids.
But,this select only shows 1 learning_record_id for each objective_id which is wrong.
Similarly,the data displayed isnot proper.
Below is the way I am getting the data now from the above SELECT.
Note:- FIRSTNAME is not correctly displayed.
FIRSTNAME EMPLID TPLAN_NAME TPLAN_ID ACTIVITIES ACTIVITIES_1
