Where-clause with the in-keyword. Query optimising.

Hi I have following question.
I have a query, e. g.
select x, y from tableA where y in (a_1, a_2, ..., a_n)
I have test it with n=1...5
1. 5-6 ms
2. 5-6 ms
3. 150 - 200 ms
4. 150 - 200 ms
5. 180 - 250 ms
There is a gap between n = 2 and n = 3. According to the execution plan the Oracle make a full table access if n >= 3. If n < 3 a an index is used. Is it possible to ensure that the index is always used?
Additionally I have test the equivalent query:
select x, y from tableA where y = a_1 or y = a_2 ... < = a_n
It showsthe same behaviour.

Hi,
I wouldn't say that the optimizer is wrong here. I would look on some more imputs.
How many values of y do you have in the table?
please post the result of:
select count(*),y
from tablea
group by y;
to see how many values of each y-value exists in the table.
For example, if there are only values 1..5 for y in the table a full table scan is the fastet answer for your query, because all values have to read!

How can I pass multiple condition in where clause with the join table?

Hi:
I need to collect several inputs at run time, and query the record according to the input.
How can I pass multiple conditions in where clause with the join table?
Thanks in advance for any help.
Regards,
TD

If you are using SQL-Plus or Reports you can use lexical parameters like:
SELECT * FROM emp &condition;
When you run the query it will ask for value of condition and you can enter what every you want. Here is a really fun query:
SELECT &columns FROM &tables &condition;
But if you are using Forms. Then you have to change the condition by SET_BLOCK_PROPERTY.
Best of luck!

Creating a where clause in the LOV query box

Hi guys is any able to help me with this one
i have a page in my app where there is a LOV drop down now the values for this drop down comes from a table that looks like this
users_for _form_TBL
E_MAIL
Vendor
[email protected]
oracle
[email protected]
sap
[email protected]
IBM
[email protected]
Oracle
[email protected]
intergraph
So my syntax for the LOV i mentioned looks like this
select VENDOR as display_value, VENDOR as return_value
from form_user_tab where E_MAIL = :APP_USER
order by 1 ;
so if [email protected] logs onto the app and has to make a selection on the LOV it would only display the vendors relative to his E_MAIL like oracle ,sap, IBM then he hits the submit button on the page then the vendor that he selected is inserted into another table .What i did on the insert table was create a trigger that after a vendor is inserted the trigger inserts a 1 into a column called assessed .
What i did after this was add a select in the where clause of the LOV so that it would check in the insert table if that vendor had been chosen before and not display it again to be selected my syntax the second time around in the SQL query box was
select VENDOR as display_value, VENDOR as return_value
from users_for _form_TBL where E_MAIL = :APP_USER
and (select 'vendor' , 'ASSESSD' from inserted _tbl_imp is null);
order by 1 ;
But im getting an error any ideas guys .Thank you

Hay man thanks for that info on the Tom Kyte Blog
--(the code you gave me )
select
    u.vendor display_value
, u.vendor return_value
from
    users_for_form_tbl u
where
    u.e_mail = :app_user
and not exists (select null from inserted_tbl_imp i where u.vendor = i.vendor)
order by
    u.vendor
--(After the error i tried )Then when i got the error i try'd using 'or exists' like this
--(code)
where
    u.e_mail = :app_user
and not exists (select null from inserted_tbl_imp i where u.vendor = i.vendor)
                      or exists (select null from inserted_tbl_imp i where u.vendor = i.vendor)
order by
    u.vendor
But the all the vendors that where in the same in the insert table came up in the drop down list example is oracle was assessed before then only oracle would appear in the drop down list and if it was assessed 3 times it would come up 3 times
--Then i tried to select where 'Assessed' is null   ('Assessed' is a column in the insert table which i created a trigger on to insert 1 in the 'ASSESSED' column when a vendor is begin assessed )
--(code)
where
    u.e_mail = :app_user
and not exists (select 'ASSESSED' from inserted_tbl_imp i where 'ASSESSED' is null )
order by
    u.vendor
This try didnt return any vendors at all
--Then i tried distinct
--(code)
where
    u.e_mail = :app_user
and not exists (select distinct 'VENDOR', from inserted_tbl_imp i where u.vendor = i.vendor)
order by
    u.vendor
This gave me a LOV ERROR
This is what i have tried so far there where others syntax's i tried last night as well but most of them came back as errors . Thanks again for you time and help fac586

Generate a where clause with outer join criteria condition: (+)=

Hi,
In my search page, I use Auto Customization Criteria mode, and I build where clause by using get Criteria():
public void initSrpQuery(Dictionary[] dic, String userName) {
int dicSize = dic.length;
StringBuffer whereClause = new StringBuffer(100);
Vector parameters = new Vector(5);
int clauseCount = 0;
int bindCount = 1;
for(int i=0; i < dicSize; i++){
String itemName = (String)(dic.get(OAViewObject.CRITERIA_ITEM_NAME));
Object value = dic[i].get(OAViewObject.CRITERIA_VALUE);
String joinCondition = (String)dic[i].get(OAViewObject.CRITERIA_JOIN_CONDITION);
String criteriaCondition = (String)dic[i].get(OAViewObject.CRITERIA_CONDITION);
String criteriaDataType = (String)dic[i].get(OAViewObject.CRITERIA_DATATYPE);
String viewAttributename = (String)dic[i].get(OAViewObject.CRITERIA_VIEW_ATTRIBUTE_NAME);
String columnName = findAttributeDef(viewAttributename).getColumnNameForQuery();
if((value != null) /*&& (!("".equals((String).trim())))*/){
if(clauseCount > 0){
whereClause.append(" AND ");
whereClause.append(columnName + " " + criteriaCondition + " :");
whereClause.append(++bindCount);
parameters.addElement(value);
clauseCount++;
If I want to generate following where clause:
select
,emp.name
,emp.email
,emp.salesrep_number
,comp.name
,gs.srp_goal_header_id
,gs.status_code
,gs.start_date
,gs.end_date
from g2c_goal_shr_emp_assignments_v emp
,jtf_rs_salesreps rs
,xxg2c_srp_goal_headers_all gs
,cn_comp_plans_all comp
where 1 = 1
and rs.salesrep_id = gs.salesrep_id (+)
and gs.comp_plan_id = comp.comp_plan_id (+)
and gs.period_year (+) = :1 -- :1 p_fiscal_year
How can I generate a where clause with outer join : gs.period_year (+) = :1 ? Will I get '(+)=' from get(OAViewObject.CRITERIA_CONDITION)?
thanks

Where-Clause with function(entered static parameter)

Hello,
I have no clue on the way to deal with this issue.
Basically, for performance, I removed a join with a table, and replaced it by a call to a function within the where clause. This function only convert the entered date into an id, in order to compare with the id in the selected table.
I knew (I think I'm right!!) that if I put a function into a where-clause, then the function is called at each row.
As the parameter of this function is a Discoverer parameter, and therefore, it's a static value, I wanted to know whether with Discoverer, there would be a way to convert the entered Discoverer parameter value into a constant that I could use within my where-clause.
To summarise, hete is the face of my query, at the moment:
SELECT myColumns
FROM myTables
WHERE thisID < myConvertedDate(:RefDate);
I would like to do this :
The User enters the :RefDate, I convert it and save the result into a constant.
Then, my query would look like :
SELECT myColumns
FROM myTables
WHERE thisID < myConstantFromDate;
I hope that my explanation is clear, and that one of you will be able to advise me.
Thanks,
Olivier

Hello Nigel,
I am not too sure that the function is called at each row. This is just my thought, from my "average" knowledge of SQL. We cannot run tkprof at the office, in order to get a better understanding.
And also, the fact that goes towards this direction is that, when I add the call to my function in the where-clause, I have the impression that the query runs more slowly than without the call.
I reckon that it would be great if the optimizer notices that the function is called with the same value, and returns always the same result.
Thanks for your comments,
Olivier

Expenditure Type LOV-- Adding where clause with controller extension- help

Hi Gurus,
I'm new to OA Framework and Java and I need to extend the controller for the expenditure type lov in iProcurement. I need to add a where clause to the VO to show only those expenditure
types that will pass transactions controls based on the project and task.
Name of the VO:ExpenditureTypeNoAwardLOVVO
controller:oracle.apps.icx.lov.webui.ExpenditureTypeLovCO
Original Query from the VO:
select * from (SELECT et.expenditure_type, et.sys_link_start_date_active,
et.sys_link_end_date_active, 1 as dummy_number
FROM pa_expenditure_types_expend_v et
WHERE et.system_linkage_function = 'VI'
and (trunc(sysdate) between et.expnd_typ_start_date_active and
nvl(et.expnd_typ_end_date_active, trunc(sysdate+1)))
and (trunc(sysdate) between et.sys_link_start_date_active and
nvl(et.sys_link_end_date_active, trunc(sysdate+1))) QRSLT
((WHERE UPPER(EXPENDITURE_TYPE) like UPPER(:1)
AND (UPPER(EXPENDITURE_TYPE) like :2 or UPPER(EXPENDITURE_TYPE) like :3
or UPPER(EXPENDITURE_TYPE) like :4 or UPPER(EXPENDITURE_TYPE) like :5)))
I created a custom database function xxpa_check_txnctl which takes project_id, task_id and expenditure type as parameters and returns "Y" if that expenditure type is valid or
returns "N" if it is not valid.
What I need to add to the where clause of the above query is
and *'Y' = ( select xxpa_check_txnctl(project_id,task_id,et.expenditure_type) from dual)* to the standard VO query so that only valid expenditure types will show up in the LOV for that
project/task combination.
I enabled the Debug Log from Diagnostics and able to see the values of project_id and task_id in the controller attached to the LOV (oracle.apps.icx.lov.webui.ExpenditureTypeLovCO) as shown
below. Please tell me how I can add the where condition to the custom controller .
I really appreciate your help.
Thanks in Advance,
Shree.

Hi, I will try to look into the issue. I have also done customizations like this in past.
To achieve this, we must read the Process request of CO properly and understand the places, where you have to make changes. In my case, I identify such places and also I couldn't extend the controller class. SO I took the code from standard CO, changed it at couple of places and created a class file with same code as standard CO but with changed at some places. After that I gave newly created CO name in personalization property, so that the page will follow newly created custom CO.
So I would suggest to read the CO properly, to understand which line is doing what......

Using where clause with like

Hi all,
im trying to set a block default where clause in the pre-query trigger of my block "customer_settlement" , to query the records that exist in a customers table like this, where the customer_name is variable based on the value entered by the user in enter-query mode before hitting the F8 key , the statement is :
set_block_property( 'customer_settlement' , default_where ,
' fk_cust_code in ( select customer_code from customers where customer_name like %' || :customer_settlement.customer_name ||'% )' );
the query doesnt work and giving me an error " unable to perform query" , notice that :customer_settlement.customer_name is an item in the block , the user change it and would like to query upon it , and its not a base table item on customer_settlement block its on customers table only . I tried all combinations of '%' and || but it seems that oracle can't see the value In the customer_name field.
any help is highly thanked.
im using Oracle form 9.0.4 and Oracle 10g Db.
Regards,
IKQ

Hi,
does this work ?
set_block_property( 'customer_settlement' , default_where ,
' fk_cust_code in ( select customer_code from customers where customer_name like '''%' || :customer_settlement.customer_name ||'%''' )' );

Where Clause in the Forms doesn't work

Hi,
I am trying to execute a query in base table block. The block property 'Query allowed' is TRUE and WHere clause is null;
I used 'SET_BLOCK_PROPERTY' and set the where clause. Did a GO_BLOCK and EXECUTE_QUERY;
The block brings all records as if there is no where clause. TO make sure I put up a message 'GET_BLOCK_PROPERTY' to see the where clause. It showed correct where clause.
null

Setting the where clause the way you did usually works, and it worked fine for me several times.
Yet, a couple of days ago I ran into something that defies my logic:
1) when using the "=" operator, it fetched me several records that satisfied the condition
2) when using the "<=" or ">=" operator it fetched only one of the records that satisfied the condition: the one that is strictly equal.
I tried using the pre-query trigger, but to no avail.
I'm looking forward for your succes.
null

Where clause with a combination of And and Or statements - Basic question

Hi,
I have a where clause with a combination of And and Or statements... May I know which one would run first
Here is the sample
WHERE SITE_NAME = 'Q' AND ET_NAME IN ('12', '15') AND TEST_DATE > DATE OR SITE_NAME = 'E' AND ET_NAME IN ('19', '20')
can you please explain how this combination works
Thanks in advance

Hi,
This reminds me of a great story. It's so good, it probably didn't really happen, but it's so good, I'm going to repeat it anyway.
IBM once had an "executive apptitude test" that they would give to job applicants. There were some questions you might call general knowlege or trivia questions, and each question had a weight (for example, answering an unimportant queestion might score one point, an important question might be 5 points.) One of the questions was "What is the standard width of a mobile home?", and the weight of the question was -20: answering the question correctly did serious harm to your score. The reasoning was that the more you knew about mobile homes, the less likely you were to be their kind of executive.
Now, as to your question, the correct answer is: I don't know. I don't want to know. Mixing ANDs and ORs without grouping them in parentheses is a really bad idea. Even if you get it right, it's going to confuse the next person who has to look at that code. Use parentheses to make sure the code is doing what you want it to do.
If you really want to find out, it's documented in the SQL language manual. Look up "Operators, prcedence"
http://docs.oracle.com/cd/E11882_01/server.112/e26088/operators001.htm#sthref815
You can easily do an experiment, using scott.emp, or even dual, where
WHERE (x AND y)
OR      zproduces different results from
WHERE   x
AND     (y OR z)

Mysterious where clause with japanese

enviroment:
PL/SQL Develope, Version 7.1.0.1337, Windows XP Professional 5.1 Build 2600 (Service Pack 2)
Here is the problem, when i add a where clause with japanese, the data evaporated:
SQL> select * from ja_test;
EXECUTABLE_NAME DESCRIPTION
XX00MRP0411C 需要供給データ作成マネージャ
SQL> select * from ja_test j where j.description = '需要供給データ作成マネージャ';
EXECUTABLE_NAME DESCRIPTION
SQL>
thanks in advance!

Thanks for replies and Sorry for my rashness, maybe the following
scripts could explain the problem more well. I create a table named
ja_test with two fields(EXECUTABLE_NAME and DESCRIPTION), both of the
type is varchar2, and there is only one record in the table,
but the DESCRIPTION contains JAPANESE characters, when i use a where
clause like this "where j.executable_name = 'XX00MRP0411C';", everything
seems work fine, but when the where clase include JAPANESE characters
like this "j.description = '需要供給データ作成マネージャ';", even if
the "j.description" is copied form database, no records returned:
SQL> select * from ja_test j where j.executable_name = 'XX00MRP0411C';
EXECUTABLE_NAME DESCRIPTION
XX00MRP0411C 需要供給データ作成マネージャ
SQL> select * from ja_test j where j.description = '需要供給データ作成マネージャ';
EXECUTABLE_NAME DESCRIPTION
SQL> desc ja_test;
Name Type Nullable Default Comments
EXECUTABLE_NAME VARCHAR2(30)
DESCRIPTION VARCHAR2(240) Y

How Do I Sort a Group of Photos on the Same Page with the same Keyword Tag?

I want to group similar photos on the same page with the same keyword tag. I have tried dragging and dropping without any success. Can anyone help?

Create an album, then search using a keyword. Select all the photos produced by the search and drag them into the album.
You can drag photos into any order in Albums and they remain in your chosen order.

Where-clause with the in-keyword. Query optimising.
