Tell me select Query that HITs the database Directly ???
Hi,
I have a table, for this table in the Techinical Setttings I selected Buffering allowed, and buffering type is Full Bufferd.Now, I want a Select Query which hits the database directly, without fetching records from the BUFFER.
Except using SELECT BYPASSING BUFFER query ????
Regards,
V.Raghavender.
hi,
· Any SELECT with a sub query or with joins
· Any set function (COUNT, MIN, MAX, SUM, AVG)
· GROUP BY
· HAVING
· SELECT DISTINCT
· ORDER BY
Examples:
SELECT /*@ SAP BYPASSING BUFFER */ * FROM MYTAB
WHERE KEY1 = ? AND KEY2 = ?
SELECT * FROM MYTAB WHERE KEY1 = ?
SELECT * FROM MYTAB
WHERE KEY1 = ? AND KEY2 = ? OR KEY1 = ?
SELECT MAX(DATA) FROM MYTAB WHERE KEY1 = ? KEY2 = ?
SELECT * FROM MYTAB
WHERE KEY1 = ? AND KEY2 = ? AND DATA =
(SELECT DATA FROM MYTAB WHERE KEY1 = ? AND KEY2 = ?)
if helpful pls award points.

How an INDEX of a Table got selected when a SELECT query hits the Database
Hi All,
How an Index got selected when a SELECT query hits the Database Table.
My SELECT query is as ahown below.
SELECT ebeln ebelp matnr FROM ekpo
APPENDING TABLE i_ebeln
FOR ALL ENTRIES IN i_mara_01
WHERE werks = p_werks AND
matnr = i_mara_01-matnr AND
bstyp EQ 'F' AND
loekz IN (' ' , 'S') AND
elikz = ' ' AND
ebeln IN s_ebeln AND
pstyp IN ('0' , '3') AND
knttp = ' ' AND
ko_prctr IN r_prctr AND
retpo = ''.
The fields in the INDEX of the Table EKPO should be in the same sequence as in the WHERE clasuse?
Regards,
VijiHi,
You minimize the size of the result set by using the WHERE and HAVING clauses. To increase the efficiency of these clauses, you should formulate them to fit with the database table indexes.
Database Indexes
Indexes speed up data selection from the database. They consist of selected fields of a table, of which a copy is then made in sorted order. If you specify the index fields correctly in a condition in the WHERE or HAVING clause, the system only searches part of the index (index range scan).
The primary index is always created automatically in the R/3 System. It consists of the primary key fields of the database table. This means that for each combination of fields in the index, there is a maximum of one line in the table. This kind of index is also known as UNIQUE. If you cannot use the primary index to determine the result set because, for example, none of the primary index fields occur in the WHERE or HAVING clause, the system searches through the entire table (full table scan). For this case, you can create secondary indexes, which can restrict the number of table entries searched to form the result set.

Filter API will hit the database if not found in Cache???
I wrote a sample program using Filter API i.e. LikeFilter, EqualsFilter which will query the cache (i.e. Map in memory) based on the criteria. But what if it doesn't found the entries in Cache . Will it then query the database with similar criteria.
I don't think so ... Please correct me if i am wrong.
I need to implement Pre-loading the cache and the link http://download.oracle.com/docs/cd/E14526_01/coh.350/e14509/preloadcache.htm#CACCFCFJ
use the Filter API. I am not sure if i can rely on pre-loading the cache from database.
Any sample example preloading the data from database into cache will be greatly appreciated
Regards,
BansiThen you won't need the Invokable code (anyway its owned by my employer ;-)
All you need to do is write a simple program something like this :
1. Query everything from the database "select * from table"
2. Iterate through the ResultSet converting them all into objects
3. Cache.put() these objects into Coherence.
Now some optimisations. Re :
1. You have a single query going to the database and will be connecting to a single cluster member. You could divide the query up by some logical division (eg. Customer / Date etc.) and then have many clients putting in concurrently, but it raises the complexity.
2. It is also possible to store List tuples in Coherence, I once worked on a very nice project along those lines.
3. Cache.putAll() is much faster than put() and you should batch these into sizes of 1000 for maximum performance.
However, I would ignore these optimisations for now (tho 3. is the most useful).
You will have to manually kick off this process when you restart your cluster (or put it in your startup script). People generally write a cluster restart script. Tho JavaServiceWrapper is very nice for restarting nodes that run out of memory. When you get really complicated you can use something like FabricServer to dynamically control your cluster, but lets get the basics working now.

Query not hitting the Aggregate
HI Gurus,
I have created a Aggregate on one info cube. now when i am executing a query which was created before the creation of aggregate then that query is hitting the Aggregate.
But i created one more new query (after the creation of aggregate) on the same infoprovider.
Now when i am checking that query is not hitting aggregate..
I am checking through RSRT --> Execute and Debug --> Display Aggregate.
Its quite strange for me...
Please help..Hi,
Thanks for your quick reply.
Let me explain my problem clearly. I am aware of that when the Aggregate contain all the characteristics that are in the query only that Aggregate is used by the report while executing it. I have few cubes on which I have created Aggregates which includes all the characteristics which are used in all the reports. Now I have created a multi provider on these cubes and created a query on that multi provider. Now when I execute the query does it hit the Aggregate or not.
For Example.
I have cubes A, B and C. A contain 1,2,3 characteristics and B contains 1,4,5 and contain 1,4,6,7. I have created Aggregates on these cubes. I have created the Multi Provider on these and executing the query. This query contain all these characteristics 1,2,3,4,5,6,7. when I run the query does it hit the any of the Aggregates.

I have been interested in how lightroom uses the catalog so was poking around a backup of the catalog. I am a database administrator and I found it rather concerning that although the database (catalog) is pretty well designed, there is no referential integrity defined or enforced. This is non-standard practice and could well be the source of corrupt catalogs I have seen many people complain about. I would strongly recommend the developers modify the catalog and adopt best practices if they want to improve the stability of Lightroom and the catalog.
I would imagine that data integrity is not enforced for performance reasons. In a closed environment like LR where the application has complete control over the data, enforcing data integrity may not be worth the performance hit. Often what is done in an environment like this is to have data integrity on in test environments which would expose data integrity bugs but where the impact of performance is low. In "production" it is then turned off to get as much performance as possible. I would say there are many more complaints about performance than corrupt catalogs. And corrupt catalogs are more likely due to interruptions in writing to the catalog (like crashes, backups or dropbox activity while LR is running, etc). Data integrity would not help in these cases as they are outside the databases control.

How to select alternate entries from the database table
Hi Experts,
can u help me, how to select alternate entries from the database table.
ThanksAs there is no concept of sequence (unless there is a field specifically included for the purpose), there is no meaning to "alternate" records.
What table do you have in mind, what data does it hold, and why do you want alternate records?

How to write select query for all the user tables in database
Can any one tell me how to select the columns from all the user tables in a database
Here I had 3columns as input...
1.phone no
2.memberid
3.sub no.
I have to select call time,record,agn from all the tables in a database...all database tables have the same column names but some may have additional columns..
Eg: select call time, record,agn from ah_t_table where phone no= 6186759765,memberid=j34563298
Query has to execute not only for this table but for all user tables in the database..all tables will start with ah_t
I am trying for this query since 30days...
Help me please....any kind of help is appreciated.....Hi,

Starting in Oracle 10, you can also use Q-notation:
http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/sql_elements003.htm#i42617
...and also can you tell me how to execute the output of this script. What front end are you using? If it's SQL*Plus, then you can SPOOL the query to a file, and then execute that file, like this:
-- Suppress SQL*Plus features that interfere with raw output
SET FEEDBACK OFF
SET PAGESIZE 0
-- Run preliminary query to generate main query
SPOOL c:\my_sql_dir\all_ah_t.sql
SELECT 'select call time, record, agn from '
|| owner

) = 1
THEN ';'
ELSE ' UNION ALL'
END AS txt

WHERE SUBSTR (table_name, 1, 4) = 'AH_T'
ORDER BY owner

How to optimize the select query that is executed in a cursor for loop?

I have executed the code below and clocked the times for every line of the code using DBMS_PROFILER.
CREATE OR REPLACE PROCEDURE TEST

p_file_id NUMBER := 151;
v_shipper_ind ah_item.shipper_ind%TYPE;

END LOOP;
DBMS_PROFILER.stop_profiler;
EXCEPTION
WHEN NO_DATA_FOUND
THEN
NULL;
WHEN TOO_MANY_ROWS
THEN
NULL;
END TEST;The SELECT query inside the cursor FOR LOOP took 773 seconds.
I have tried using BULK COLLECT instead of cursor for loop but it did not help.
When I took out the select query separately and executed with a sample value then it gave the results in a flash of second.
All the tables have primary key indexes.
Any ideas what can be done to make this code perform better?
Thanks,
Raj.As suggested I'd try merging the queries into a single SQL. You could also rewrite your IN clauses as JOINs and see if that helps, e.g.
SELECT DISTINCT ai.shipper_ind, ai.special_sales_reserve_ind, ai.exe_location_ind
INTO v_shipper_ind, v_sales_reserve_ind, v_location_indicator
FROM ah_item ai, ah_item_xref aix, ah_chain_div_facility acdf, ah_div ad
WHERE ai.item_id_edw = aix.item_id_edw
AND aix.item_code_cust = rec.item_code_cust
AND aix.facility_num = acdf.facility_code
AND acdf.chain_id = ah_internal_data_pkg.get_chain_id (p_file_id)
AND acdf.div_id = ad.div_id
AND ad.division = rec.division;ALSO: You are calling ah_internal_data_pkg.get_chain_id (p_file_id) every time. Why not do it outside the loop and just use a variable in the inner query? That will prevent context switching and improve speed.

Select query that eliminate duplicates
I am struck at the below scenario. need your help in modify my query based on the below sample data. My objective is to create a EVENT AND EVENT_LOW using the data available from TEM_GT and TXN table.
TEM_GT (global temporary table)
est_id primary key, trans_id, trp_id, amount
1 111 2221 1.5
2 111 3332 2.0
3 112 4443 3.0
TXN table
trans_id, trans_type
111 type1
112 type1
EVENT table
event_id primary key, trans_id, trans_type, flag.
1000 111 type1 N
1001 112 type1 N
EVENT_LOW table
event_low_id primary key, event_id, est_id, amount.
9991 1000 1 1.5
9992 1000 1 2.0
9993 1001 2 3.0
insert into(event_low_id, event_id, est_id, amount)
select event_low_id_s.nextval e.event_id, tg.est_id, tg.amount from
from TEM_GT tg, EVENT e
WHERE
tg.trans_id = e.trans_id
AND e.flag = 'N'
Based on TEM_GT and TXN gt, populating data into EVENT table. Now when I try to populate data in the EVENT_LOW table, the above query returns 5 rows instead of 3 rows. This is due to trp_id in TEM_GT table. I do not want to add trp_id in EVENT table, and want to handle the duplicate elimination in the above select query.
I wrote the below sql. It almost resolve my problem. But sometimes it returns different value for the amount column. I wanted my event_low result as below for the est_id 1.
event_low_id primary key, event_id, est_id, amount.
9991 1000 1 1.5
9992 1000 1 2.0
But sometime it returns as below
event_low_id primary key, event_id, est_id, amount.
9991 1000 1 1.5
9992 1000 1 1.5
or
event_low_id primary key, event_id, est_id, amount.
9991 1000 1 2.0
9992 1000 1 2.0
select *
from (select x.*,
row_number() over (partition by event_id order by event_id) rn
from (seelct e.event_id, tg.est_id, tg.amount
from TEM_GT tg, EVENT e
WHERE
tg.trans_id = e.trans_id
AND e.flag = 'N'
) x
where rn = 1
I am using Oracle 11g. Any help. Thanks in advance.Hi Suresh,
Please read SQL and PL/SQL FAQ
Whenever you create a thread always post sample data as CREATE TABLE and INSERT statements.
Additionally when you put some code or output please enclose it between two lines starting with {noformat}{noformat}
i.e.:
{noformat}{noformat}
SELECT ...
{noformat}{noformat}
Regarding your problem you said:
Based on TEM_GT and TXN gt, populating data into EVENT table. Now when I try to populate data in the EVENT_LOW table, the above query returns 5 rows instead of 3 rows.
The above query cannot return 5 rows with the data you have posted. You have 3 rows in TEM_GT and 2 rows in EVENT table. The table are joined ontg.trans_id = e.trans_id AND e.flag = 'N'
And the result of the query with your posted data is *3 rows*. So try to be clear.
If your intention is to insert into EVENT_LOW only one row from TEM_GT for the same trans_id then you have to tell us which is the criteria to choose the row between the duplicates (the first by est_id order??).
Also be careful to post valid statements. The statement below is not valid as it is missing the table name after INSERT INTO and there are 2 consecutive FROM keywords:insert into(event_low_id, event_id, est_id, amount)
select event_low_id_s.nextval e.event_id, tg.est_id, tg.amount from
from TEM_GT tg, EVENT e
WHERE
tg.trans_id = e.trans_id
AND e.flag = 'N'
I will make the assumption that you want to select the first row order by est_id during insertion. If this is not what you want, please change the analytic function:INSERT INTO event_low (event_low_id, event_id, est_id, amount)
WITH got_data AS
SELECT e.event_id, tg.est_id, tg.amount
, ROW_NUMBER() OVER(PARTITION BY tg.trans_id ORDER BY tg.est_id) AS rn
FROM tem_gt tg, event e
WHERE tg.trans_id = e.trans_id
AND e.flag = 'N'
SELECT event_low_id_s.NEXTVAL
, event_id, est_id, amount
FROM got_data
WHERE rn = 1;
If this is not what you want please post CREATE TABLE and INSERT statement, and post your expected output (for insertion into EVENT_LOW table) for the data you have posted.
Regards.

Parsing a String object that contains the database details in jsp
Hi All,
In my project i have a model which is a bean that contains
a method :-
UserBean.java
....getUserData()
//the database connection is written here.
st.executeUpdate("insert ----------");
In the servlet i am calling the bean,
ControllerServlet.java
UserBean ub=new UserBean();
Object obj=ub.getUserData();
session.putValue("something",obj); //Here the obj contains all the database datas that is used in insert query
//By using RequestDispacher i am forwarding this request & the response
to the jsp page
ViewJsp.jsp
String data=(String)session.getValue("something");
//Here "data" now contains all the database contents that is stored using insert query in the bean
From here i need to parse the "data" in order to display the contents
stored in the string "data" in to a html table.
Plz. do provide a solution for this.It is very Urgent at the moment.
So that i will be very thankful to u.
Thanx,
contactananthok, first of all, in getData, i assume you do a SELECT, not an INSERT,
so your bean code should look like:
ResultSet rs = st.executeQuery(...) // or somethig like that
return rs; // it will contain the data you needand in the jsp you write:
ResultSet rs = (ResultSet)session.getValue("something");
instead of
String data=(String)session.getValue("something");
i assume you know how to work with a ResultSet -
Problem with select query that includes a date
I've been fighting with this for about 4 hours - yes, quite literally... I've never been good with date stuff. I have a brain block.
Anyway, here's the situation:
I have an Access database that has a time/date field. There are no times, just a date in mm/dd/yyyy format.
That table is a list of classes held for the past three years. I want to make a query that only shows the classes that have ended after January 1 of this year. I don't want to put 01/01/2010 in the query itself because I want it to still work next year.
This is the current query:
<cfquery name="classes" datasource="#DSN#" dbtype="ODBC">
SELECT classesTitles.ClassTitle, classesTitles.ClassDesc, classCatagories.catagoryName, classes.classStart, classes.classEnd, classes.classNotes, owners.fName, owners.lName, classTime.timeSlot, classes.classID, classes.classLimit
FROM classCatagories INNER JOIN (((classes INNER JOIN classesTitles ON classes.classTitle = classesTitles.classTitleID) INNER JOIN classTime ON classes.classTime = classTime.timeID) INNER JOIN owners ON classes.classInstructor = owners.ownerID) ON classCatagories.catagoryID = classesTitles.ClassType
WHERE classes.classEnd < 01/01/#DatePart("yyyy", now())#
ORDER BY classes.classStart, classCatagories.catagoryName, classTime.timeSlot, classesTitles.ClassTitle
</cfquery>
I don't get any results, but I should get a list of every class that has an end date before January 1 of this year - about 200 records.
When I swap around the where clause to:
<cfquery name="classes" datasource="#DSN#" dbtype="ODBC">
SELECT classesTitles.ClassTitle, classesTitles.ClassDesc, classCatagories.catagoryName, classes.classStart, classes.classEnd, classes.classNotes, owners.fName, owners.lName, classTime.timeSlot, classes.classID, classes.classLimit
FROM classCatagories INNER JOIN (((classes INNER JOIN classesTitles ON classes.classTitle = classesTitles.classTitleID) INNER JOIN classTime ON classes.classTime = classTime.timeID) INNER JOIN owners ON classes.classInstructor = owners.ownerID) ON classCatagories.catagoryID = classesTitles.ClassType
WHERE classes.classEnd > 01/01/#DatePart("yyyy", now())#
ORDER BY classes.classStart, classCatagories.catagoryName, classTime.timeSlot, classesTitles.ClassTitle
</cfquery>
I get EVERY class in the database, and I should only be getting about 50
The classes are about 8 weeks long, the begin date and end date are in the database as date/time fields, so I need to show everything that ended in 2010, regardless of when it started.
I'm sure it's something glaringly obvious, but it's escaping me.
THANKS
MichelleThe format of your date field in access is irrelevent to the situation at hand. Use proper date objects instead of trying to build a suitable string. For the first of January of the current year, the coldfusion functions createdate(), year(), and now() are your freinds. Then, in case Adam's post was not clear, use cfqueryparam with the resulting variable.
