How can i run this query in BI Answers
Hi,
pls tell me how can i run this sql statement in BI Answers....???
select abc_date,abc_asset_desc,sum(nvl(abc_market_val_lcy,0)+nvl(abc_accr_lcy,0)) "total balance" from abc
group by abc_date,abc_asset_desc;any help would be appriciated.... :-)
Regards
Strange question this one.
normally with Answers you pick the columns you want to report on and the BI server will construct the SQL for you.
In this example you would need a star with the abc dimension logical table and a logical fact for abc (these can be in the same table), which has a calculated field for 'Total Balance'.
You then pick the columns you require and Answer and the BI will automatically add the group by.

Hi guys i am beginner , just wanted to know some info , how can i improve this query ..
select *
from tableA A, viewB B,
where A.key = B.key
and a.criteria1 = '111'
and a.criteria2 = some_funtion(a.key)
one more thing should function should be on left side of equal sign.
will a join make it better or something else is needed more than that .952936 wrote:

will a join make it better or something else is needed more than that .If you are a beginner try to learn the ANSI Syntax. This will help you a lot to write better queries.
Your select would look like this in ANSI.
select *
from tableA A
JOIN viewB B ON A.key = B.key
WHERE a.criteria1 = '111'
and a.criteria2 = some_function(a.key);The good thing here is that this separates the typical joining part of the select from the typical filter criteria.
The other syntax very often let you forget one join. Just because there are so many tables and so many filters, that you just don't notice correctly anymore what was join and what not.
If you notice that the number of column is not what you expect, you can easiely modify the query and compare the results.
example A
Remove View B from the query (temporarily comment it out).
select *
from tableA A
--JOIN viewB B ON A.key = B.key
WHERE a.criteria1 = '111'
and a.criteria2 = some_funtion(a.key)
example B
You notice, that values from A are missing. Maybe because there is no matching key in ViewB? Then change the join to an outer join.
select *
from tableA A
LEFT OUTER JOIN viewB B ON A.key = B.key
WHERE a.criteria1 = '111'
and a.criteria2 = some_funtion(a.key)(The outer keyword is optional, left join would be enough). -
How can i run this code correctly?
hello, everybody:
when i run the code, i found that it dons't work,so ,i hope somebody can help me!
the Ball class is this :
package {
import flash.display.Sprite;
[SWF(width = "550", height = "400")]
public class Ball extends Sprite {
private var radius:Number;
private var color:uint;
private var vx:Number;
private var vy:Number;
public function Ball(radius:Number=40, color:uint=0xff9900,
vx:Number =0, vy:Number =0) {
this.radius= radius;
this.color = color;
this.vx = vx;
this.vy = vy;
init();
private function init():void {
graphics.beginFill(color);
graphics.drawCircle(0,0,radius);
graphics.endFill();
and the Chain class code is :
package {
import flash.display.Sprite;
import flash.events.Event;
[SWF(width = "550", height = "400")]
public class Chain extends Sprite {
private var ball0:Ball;
private var ball1:Ball;
private var ball2:Ball;
private var spring:Number = 0.1;
private var friction:Number = 0.8;
private var gravity:Number = 5;
//private var vx:Number =0;
//private var vy:Number = 0;
public function Chain() {
init();
public function init():void {
ball0 = new Ball(20);
addChild(ball0);
ball1 = new Ball(20);
addChild(ball1);
ball2 = new Ball(20);
addChild(ball2);
addEventListener(Event.ENTER_FRAME, onEnterFrame);
private function onEnterFrame(event:Event):void {
moveBall(ball0, mouseX, mouseY);
moveBall(ball1, ball0.x, ball0.y);
moveBall(ball2, ball1.x, ball1.y);
graphics.clear();
graphics.lineStyle(1);
graphics.moveTo(mouseX, mouseY);
graphics.lineTo(ball0.x, ball0.y);
graphics.lineTo(ball1.x, ball1.y);
graphics.lineTo(ball2.x, ball2.y);
private function moveBall(ball:Ball,
targetX:Number,
targetY:Number):void {
ball.vx += (targetX - ball.x) * spring;
ball.vy += (targetY - ball.y) * spring;
ball.vy += gravity;
ball.vx *= friction;
ball.vy *= friction;
ball.x += vx;
ball.y += vy;
thanks every body's help!ok, thanks for your reply ! I run this code in the Flex builder 3!and the Ball class and the Chain class are all in the same AS project!
and i changed the ball.pv property as public in the Ball class, and the Chain class has no wrong syntactic analysis,but the AS code don't run.so this is the problem.

收件人: fang alvin <[email protected]>
I don't see that the Ball class has a pv property, or that you even try to access a pv property in the Chain class. All of the properties in your Ball class are declared as private, so you probably cannot access them directly. They would need to be public. Also, I still don't see where you import Ball in the chain class such that it can use it. -

PLEASE IF YOU FIND SOMETHING WRONG.. PLEASE HELP ME.. this query takes me aproximatelly 10 minutes and the database is really small ( with only 200 records on each table )You are querying eight tables, however in any of your OR predicates you're only restricting 3 or 4 of those tables. That means that the remaining 4 or 5 tables are generating cartesian products. (n.b. the cartesian product of 5 tables with 200 rows each results in g 200^5 = 320,000,000,000 rows) Then you casually hide this behind "distinct".
A simple restatement of your requirements looks like this:
Select eopersona.numident
From rscompeten,
rscompet,
rscv,
eopersona
Where LOWER (rscompeten.nombre) LIKE '%caracas%'
AND rscompeten.id = rscompet.idcompeten
AND rscv.id = rscompet.idcv
AND eopersona.id = rscv.idpersona
UNION
Select eopersona.numident
From rscurso ,
rscv,
eopersona
Where LOWER (rscurso.nombre) LIKE '%caracas%'
AND rscv.id = rscurso.idcv
AND eopersona.id = rscv.idpersona
UNION
Select eopersona.numident
From rscurso ,
rscv,
eopersona
Where LOWER (rscurso.lugar) LIKE '%caracas%'
AND rscv.id = rscurso.idcv
AND eopersona.id = rscv.idpersona
UNION
...From there you can eliminate redundancies as desired, but I imagine that the above will perform admirably with the data volumes you describe. -

These errors typically occur when security software interferes with the restore and update process. Use the steps to troubleshoot security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See the steps under the heading "Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store." If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.

How can i make this query run for a form
This query works fine for a sql report
SELECT *
FROM STUDENTS
WHERE given_name||' '||family_name = :P101_USERNAME
AND password = :P101_PASSWORD;
But i want it to do the same thing for a form but i dont have the option like i do for the report where i can just apply the condition to the process.
Anyone any ideas how i could do this so that when i go to the form this information is already there based on the username and password from the previous page?Assuming that page 101 is your login form, just lookup the primary key of the student based on the values presented in the login page fields, then set and pass this value to the form page.
So you would create a process that runs near the very end of the the login processes on page 101, something like this:
declare
l_student_id students.student_id%TYPE;
begin
select student_id into l_student_id from students where given_name||' '||family_name = :P101_USERNAME and password = :P101_PASSWORD;
-- then set the value of your form page primary key field
:P1_STUDENT_ID := l_student_id;
end;I've done something similar and it works fine for me, although I haven't looked at it recently.

How can we rewrite this query for better performance
Hi All,
The below query is taking more time to run. Any ideas how to improve the performance by rewriting the query using NOT EXITS or any other way...
Help Appreciated.
/* Formatted on 2012/04/25 18:00 (Formatter Plus v4.8.8) */
SELECT vendor_id
FROM po_vendors
WHERE end_date_active IS NULL
AND enabled_flag = 'Y'
and vendor_id NOT IN ( /* Formatted on 2012/04/25 18:25 (Formatter Plus v4.8.8) */
SELECT vendor_id
FROM po_headers_all
WHERE TO_DATE (creation_date) BETWEEN TO_DATE (SYSDATE - 365)
AND TO_DATE (SYSDATE))
ThanksTry this one :
This will help you for partial fetching of data
SELECT /*+ first_rows(50) no_cpu_costing */
vendor_id
FROM po_vendors
WHERE end_date_active IS NULL
AND enabled_flag = 'Y'
AND vendor_id NOT IN (
SELECT vendor_id
FROM po_headers_all
WHERE TO_DATE (creation_date) BETWEEN TO_DATE (SYSDATE - 365)
AND TO_DATE (SYSDATE))
overall your query is also fine, because, the in this query the subquery always contain less data compare to main query. -

#####2 ideas:
1. Inline function to perform the CASE funcionaltity for you
2. Piplelined function to generate the entire dataset
Both will be slower than just using CASE in a query, but we're working around big constraints -

ORDER BY MANIF_PARCL_HDR.MANIF_NBR ASC,
MANIF_PARCL_HDR.MANIF_TYPE ASCand then compare how fast that runs and what the explain plan is, etc. -
How can i speedup this query ?
Hi,
have a look at this query:
SELECT DISTINCT element_short_description
FROM sample_test_report, test_group, test_element_master
WHERE str_test_group_code = tgr_test_group_code
AND str_element_code = element_code
AND tgr_group_description = 'SINTER_CHEMICAL_ANALYSIS'
ORDER BY element_short_descriptionThing is that total number of rows present in "sample_test_report" tables are in lakh ...around 50 lakh.Other two tables have a few rows. This query is taking around 15 seconds for completion, can this query be made faster ?
Note that proper indexing have been done already.
Thanks.SELECT DISTINCT element_short_description
FROM sample_test_report, test_group, test_element_master
WHERE str_test_group_code = tgr_test_group_code
AND str_element_code = element_code
AND tgr_group_description = 'SINTER_CHEMICAL_ANALYSIS'
ORDER BY element_short_description
Can you provide us with explain plan?
I suggest you use table alias every time:
The alias is specified in the FROM clause after each table name.
Table aliases make your queries more readable.
Then gather statistics your tables:
BEGIN
DBMS_STATS.GATHER_TABLE_STATS('OWNER','TABLE',estimate_percent=>NULL,method_opt=>'FOR ALL INDEXED COLUMNS SIZE AUTO',DEGREE=>10,CASCADE=>TRUE,granularity=>'ALL');
END;
if your db version < 10g
ANALYZE TABLE employees COMPUTE STATISTICS;
ANALYZE TABLE employees ESTIMATE STATISTICS;
If necessary rebuild index, check indexes are use.
Unusable indexes are made valid by rebuilding them to recalculate the pointers.
Rebuilding an unusable index re-creates the index in a new location, and then drops the unusable index. This can be done either by using Enterprise Manager or through SQL commands:
ALTER INDEX HR.emp_empid_pk REBUILD;
ALTER INDEX HR.emp_empid_pk REBUILD ONLINE;
ALTER INDEX HR.email REBUILD TABLESPACE USERS;
Note: Rebuilding an index requires that free space be available for the rebuild. Verify that there is sufficient space before attempting the rebuild. Enterprise Manager checks space requirements automatically.
At the end, try join table separately and then concatenate them.
Your query will be work good.
Look at execution plan, if indexes are not used, use HINTs : There are many Oracle hints available to the developer for use in tuning SQL statements that are embedded in PL/SQL.
please refer to http://www.dba-oracle.com/t_sql_hints_tuning.htm and http://www.adp-gmbh.ch/ora/sql/hints/index.html
Good luck -

Hi All,
Please look into the above data, If analytic function LAG(),CASE expression are possible to locate the cursor position in the single query, then any one can help me out about it. I tried but could not.
Regards,
Neel.You can do this with the SUM analytic function. Taking the emp table, for example,
1 select ename, sal, SUM(sal) OVER (order by empno)
2 from emp
3* order by empno
SQL> /
ENAME SAL SUM(SAL)OVER(ORDERBYEMPNO)
