Report Query with Bind variables working very slowly

Hi everyone,
I'm having a hard time with one of my Reports.
Basically the query looks like this:
Select *
from x,y,z
where x.lang_id = :P1_LANG
and y.name = :P1_LANG;
I have a textfield and a Select List on my Page which have to have a value before the report is shown.
Now to the problem, when I input a value into these Application Items the Report takes ages (3-5 min). But when I replace the Bind variables (:P1_LANG and :P1_LANG) with the actual values it takes mere seconds.
Anyone got an idea why this might be?
I'm at my wits end -.-

Hi
This could be for a number of reasons and unfortunately there is no quick answer...
When you run a query for the first time, the execution plan is worked out by the Cost Based Optimiser (I'm assuming you're using 10g or above here). This is referred to as a hard parse. Next time the same SQL text is used then the execution plan may still be in the shared pool - in this case the same execution plan is used rather than being calculated again.
The great thing about using bind variables is that even with different inputs, the SQL text is the same so the execution plan can be shared for different inputs. One downside is that if the first time the query is executed using bind variables, out of the ordinary values are input, bind variable peeking can lead to a sub optimal execution plan being calculated for the query and then shared in other situations (where more 'normal' values are input).
However, it could be down to a host of other things too. So your first check is to make sure that you have executed both queries a number of times. If you are still getting the same performance issues then plan post the full query, table creation scripts and execution plan for both querys.

Report query with bind variable

Trying to create a report query for xsl-fo print. For output format I pick "derive from item" then pick the item name from the list, on the next screen, I paste the query with the bind variable. on the next step test query, I always get "data not found" regardless what value I type in. This is the same query that I ran under sql commands without any issues.
Does anyone run into the same issue as I have when attempted to create a query with bind var ? There is no problem creating a query without bind varibles. . thanks.

Hi, please did you get any solution to this issue? I am having similar challenge right now.
select     EMP.DEPTNO as DEPTNO,
     DEPT.DNAME as DNAME,
     EMP.EMPNO as EMPNO,
     EMP.ENAME as ENAME,
     EMP.JOB as JOB,
     EMP.MGR as MGR,
     EMP.HIREDATE as HIREDATE,
     EMP.SAL as SAL
from     SCOTT.DEPT DEPT,
     SCOTT.EMP EMP
where EMP.DEPTNO=DEPT.DEPTNO
and      DEPT.DNAME =upper(:dname)
This run perfectly in sql developer, toad, and even inside publisher if I login directly to publisher to create report.
Generating this same query in shared component query builder and testing it returns no data found. If I remove the last line, it works. but with the last line, it return no data found. It seems no one has been able to provide solution to this issue

Report Performance with Bind Variable

Getting some very odd behaviour with a report in APEX v 3.2.1.00.10
I have a complex query that takes 5 seconds to return via TOAD, but takes from 5 to 10 minutes in an APEX report.
I've narrowed it down to one particular bind. If I hard code the date in it returns in 6 seconds, but if I let the date be passed in from a parameter it takes 5+ minutes again.
Relevant part of the query (an inline view) is:
,(select rglr_lect lect
,sum(tpm) mtr_tpm
,sum(enrols) mtr_enrols
from ops_dash_meetings_report
where meet_ev_date between to_date(:P35_END_DATE,'DD/MM/YYYY') - 363 and to_date(:P35_END_DATE,'DD/MM/YYYY')
group by rglr_lect) RPV
I've tried replacing the "to_date(:P35_END_DATE,'DD/MM/YYYY') - 363" with another item which is populated with the date required (and verified by checking session state). If I replace the :P35_END_DATE with an actual date the performance is fine again.
The weird thing is that a trace file shows me exactly the same Explain Plan as the TOAD Explain where it runs in 5 seconds.
Another odd thing is that another page in my application has the same inline view and doesn't hit the performance problem.
The trace file did show some control characters (circumflex M) after each line of this report's query where these weren't anywhere else on the trace queries. I wondered if there was some sort of corruption in the source?
No problems due to pagination as the result set is only 31 records and all being displayed.
Really stumped here. Any advice or pointers would be most welcome.
Jon.

Don't worry about the Time column, the cost and cardinality are more important to see whther the CBO is making different decisions for whatever reason.
Remember that the explain plan shows the expected execution plan and a trace shows the actual execution plan. So what you want to do is compare the query with bind variables from an APEX page trace to a trace from TOAD (or sqlplus or whatever). You can do this outside APEX like this...
ALTER SESSION SET EVENTS '10046 trace name context forever, level 1';Enter and run your SQL statement...;
ALTER SESSION SET sql_trace=FALSE;This will create a a trace file in the directory returned by...
SELECT value FROM v$parameter WHERE name = 'user_dump_dest' Which you can use tkprof to format.
I am assuming that your not going over DB links or anything else slightly unusual?

Query with bind variable, how can use it in managed bean ?

Hi
I create query with bind variable (BindControlTextValue), this query return description of value that i set in BindControlTextValue variable, how can i use this query in managed bean? I need to set this value in String parameter in managed bean.
Thanks

Put the query in a VO and execute it the usual way.
If you need to, you can write a parameterized method in VOImpl that executes the VO query with the parameter and then call that method from the UI (as a methodAction binding) either through the managed bean or via a direct button click on the page.

SQL query with Bind variable with slower execution plan

I have a 'normal' sql select-insert statement (not using bind variable) and it yields the following execution plan:-

I have the same query but instead running using bind variable (I test it with both oracle form and SQL*plus), it takes considerably longer with a different execution plan:-

TABLEA has around 3million record while TABLEB has 300 records. Is there anyway I can improve the speed of the sql query with bind variable? I have DBA Access to the database
Regards
Ivan

Many thanks for your reply.
I have run the statistic already for the both tableA and tableB as well all the indexes associated with both table (using dbms_stats, I am on 9i db ) but not the indexed columns.
for table I use:-
begin
dbms_stats.gather_table_stats(ownname=> 'IVAN', tabname=> 'TABLEA', partname=> NULL);
end;
for index I use:-
begin
dbms_stats.gather_index_stats(ownname=> 'IVAN', indname=> 'TABLEB_IDX_003', partname=> NULL);
end;
Is it possible to show me a sample of how to collect statisc for INDEX columns stats?

SLOW report performance with bind variable

Environment: 11.1.0.7.2, Apex 4.01.
I've got a simplified report page where the report runs slowly compared to running the same query in sqldeveloper. The report region is based on a pl/sql function returning a query. If I use a bind variable in the query inside apex it takes 13 seconds to run, and if I hard code a string it takes only a few hundredths of a second. The query returns one row from a table which has 1.6 million rows. Statistics are up-to-date and the columns in the joins and where clause are indexed.
I've run traces using p_trace=YES from Apex for both the bind variable and hard coded strings. They are below.
The sqldeveloper explain plan is identical to the bind variable plan from the trace, yet the query runs in 0.0x seconds in sqldeveloper.
What is it about bind variable syntax in Apex that is causing the bad execution plan? Apex Bug? 11g bug? Ideas?
tkprof output from Apex trace with bind variable is below...

Patrick, interesting insight. Thank you.
The optimizer must be peeking at my bind variables with it's eyes closed. I'm the only one testing and I've never passed %anything as a bind value. :)
Here's what I've learned since my last post:
I don't think that sqldeveloper is actually using the explain plan it says it is. When I run explain plan in sqldeveloper (with a bind variable) it shows me the exact same plan as Apex with a bind variable. However, when I run autotrace in sqldeveloper, it takes a path that matches the hard coded values, and returns results in half a second. That autotrace run is consistent with actually running the query outside of autotrace. So, I think either sqldeveloper isn't really using bind variables, OR it is using them in some other way that Apex does not, or maybe optimizer peeking works in sqldeveloper?
Using optimizer hints to tweak the plan helps. I've tried both /*+ FIRST_ROWS */ and /*+ index(ps pk_persons) */ and both drop the query to about a second. However, I'm loath to use hints because of the very dynamic nature of the query (and Tom Kyte doesn't like them either). The hints may end up hurting other variations on the query.
I also tested the query by wrapping it in a select count(1) from ([long query]) and testing the performance in sqldeveloper and in Apex. The performance in that case is identical with both bind variables and hard coded variables for both Apex and SqlDeveloper. That to me was very interesting and I went so far as to set up two bind variable report regions on the same page. One region wrapped the long query with select count(1) from (...) and the other didn't. The wrapped query ran in 0.01 seconds, the unwrapped took 15ish seconds with no other optimizations. Very strange.
To get performance up to acceptable levels I have changed my function returning query to:
1) Set the equality operator to "=" for values without wildcards and "like" for user input with wildcards. This makes a HUGE difference IF no wildcard is used.
2) Insert a /*+ FIRST_ROWS */ hint when users chose the column that requires the sub-query. This obviously changes the optimizer's plan and improves query speed from 15 seconds to 1.5 seconds even with wildcards.
I will NOT be hard coding any user supplied values in the query string. As you can probably tell by the query, this is an application where sql injection would be very bad.
Jeff, regarding your question about "like '%' || :P71_SEARCH_SOURCE1 || '%'". I've found that putting wildcards around values, particularly at the beginning will negate any indexing on the column in question and slows performance even more.
I'm still left wondering if there isn't something in Apex that is breaking the optimizer "peeking" that Patrick describes. Perhaps something in the way it switches contexts from apex_public_user to the workspace schema?

Af:query with bind variables and Saved Search

I have a VO and view criteria(VC).
VC has a criteria item ObsoleteDate with range specified as bindVariables "dateFrm" and "dateTo" I dragged & dropped the named criteria as af:Query with table. Table toolbar has 2 buttons in which I set & clear the bind variables. Data is fetched as per as expected based on the VC & bind variables.
The problem is,
If I save my search with bind variables set and swap between the saved searches , all works fine. But the moment I clear bind variables & swap between searches.. "dateFrm" is populated and "dateTo" is null and I get an Exception oracle.jbo.AttrValException: JBO-27035: Attribute Obsolete Date: is required.
Why is this happening?? Saved search is supposed to save the VC with all the bind values set while saving and clearing bind variables shouldn't affect the saved search, right?? Or I have understood it wrong?
I am using JDeveloper 11.1.2.3.0
Thanks

ODT Query Window. Query with binding variable?

I have the ODT 11.1.0.7.20 installed.
In "Query Window", I execute an SQL with binding variables. But I only get ORA-01008 errors. How do I do that?
I want to double click an SQL and load it in "Query Window". How do I do that?
I want to right click an SQL and select "Open with Query Window". How do I do that?
In Query Window I want to load an SQL either by drag and drop or by select a function "Open SQL". How do I do that?
Why none of these functionalities work as you could expect?
Thanks,
Tobias

Finally i found the problem..
The problem was that i had to remove one line from the properties of my table departments, the property: selectedrowkeys, because it only passed the last selected row.
Still, i apreciate the help and i had to replace some code in the bean.java , because of the exception error and you didn't had to do that. Maybe i did some configuration in the wrong way and it went wrong.
Thanks for the help.

How to add '%' to a query with bind variables

Hi,
I am using oracle jdeveloper 11g.
I am trying to create a table to display rows using the below query in a jspx page,
select * from ade_txns where series='WORKPLACE_PT.11.1.1.8.0_GENERIC' and transaction like 'rkumara%'
I am using a view with query and binding variables as below,
select * from ade_txns where series= :p_series and transaction like :p_QAEngineer
I will be passing p_QAEngineer using binding variable using 'ExecuteWithParams' using a dropdown(eg: 'rkumara'). But I need to add a '%' to this value as I am using a 'LIKE' clause in my query.
I tried using,
select * from ade_txns where series= :p_series and transaction like :p_QAEngineer+'%'
But this is not working for me.
Can someone please tell me how i can solve this.
Thanks,
Ranjeet

Create collection from query with bind variable

LOV query with bind variable

Hi,
I have a LOV with a query has a bind variable:
select comp_plan_id,name from cn_comp_plans_all
where sysdate between start_date and nvl(end_date,sysdate+1)
and org_id = : 1
So I create a CO for this LOV , and in processRequest(), I pass the value of this bind varible.
Now in the base page,
if comp plan crteria is blank, this LOV works fine.
if comp plan criteria has value: 2007 PTE COMP PLAN 1001
I get this error:

Because '2007 PTE COMP PLAN 1001' has 5 tokens, the generated query automatically add 'Name' 5 times.
Can anyone help?

Using a query with bind variable with columns defined as raw

Hi,
We are on Oracle 10.2.0.4 on Solaris 8. I have a table that has 2 columns defined as raw(18). I have a query from the front end that queries these two raw columns and it uses bind vairables. The query has a performance issue that I need to reproduce but my difficulty is that how to test the query in sqlplus using bind variables (the syntax for bind vairables fails for columns with raw datatype).
SQL> DESC TEST
Name                                      Null?    Type
ID1                                                RAW(18)
ID2                                                RAW(18)
SQL> variable b1 RAW(18);
Usage: VAR[IABLE] [ <variable> [ NUMBER | CHAR | CHAR (n [CHAR|BYTE]) |
                    VARCHAR2 (n [CHAR|BYTE]) | NCHAR | NCHAR (n) |
                    NVARCHAR2 (n) | CLOB | NCLOB | REFCURSOR |
                    BINARY_FLOAT | BINARY_DOUBLE ] ]
The above is the error I get - i cant declare a variable as raw.
SQL> variable b2 RAW(18);
Usage: VAR[IABLE] [ <variable> [ NUMBER | CHAR | CHAR (n [CHAR|BYTE]) |
                    VARCHAR2 (n [CHAR|BYTE]) | NCHAR | NCHAR (n) |
                    NVARCHAR2 (n) | CLOB | NCLOB | REFCURSOR |
                    BINARY_FLOAT | BINARY_DOUBLE ] ]
SQL> variable b3 RAW(18);
Usage: VAR[IABLE] [ <variable> [ NUMBER | CHAR | CHAR (n [CHAR|BYTE]) |
                    VARCHAR2 (n [CHAR|BYTE]) | NCHAR | NCHAR (n) |
                    NVARCHAR2 (n) | CLOB | NCLOB | REFCURSOR |
                    BINARY_FLOAT | BINARY_DOUBLE ] ]
--now the actual query below
SQL> SELECT * FROM TEST WHERE ID1=:B1 AND ID2 BETWEEN :B2 AND :B3;
SP2-0552: Bind variable "B3" not declared.
(this fails due to the errors earlier)Also this is a third party app schema so that we don't have the option of modifying the data type of the columns.
Thanks,

Try anonymous PL/SQL block:
declare
b1 RAW(18);
b2 RAW(18);
b3 RAW(18);
begin
b1:=..;
b2:=..;
b3:=..;
SELECT col1, col2, ..
INTO ...
FROM TEST
WHERE ID1=:B1
AND ID2 BETWEEN :B2 AND :B3;
end;

Query With Bind Variables and %

Hi,
Quick question. I am using ADF BC on Jdev 11 with a MySQL Database.
I've used Bind Variables in the past (I have to use a Question Mark [?]) and have had no problem.
Now I want to do something like this in my where clause:
SELECT TempTable.ABC FROM TempTable
WHERE ABC LIKE ?%
When I try and create the View Object with that query it is complaining about the %.
Am I required to append the % in my bind variable? Any examples I have seen of this, people are doing something like :p_id = 'Jo%'

Try
like ? || '%'

Repeated rows resulting from executeWithParams on query with bind variable

hi
Please consider this example application created using JDeveloper 11.1.1.3.0
at http://www.consideringred.com/files/oracle/2010/RepeatedRowsIssueApp-v0.01.zip
It has a View Object "EmployeesVO" based on a SQL query with a bind variable "EmailBVar".
The page "findEmployees.jspx" has executeWithParams dropped as an "ADF Parameter Form..." and the "EmployeesVOVI" collection as a table.
On "EmployeesVOVIIterator" the RangeSize has been modified from the default 25 to 10.
So, all straightforward stuff.
A scenario (sc1), running the page "findEmployees.jspx", specifying a value and clicking the "ExecuteWithParams" button results in repeated rows shown in the table, that is the first row (and subsequent rows) are repeated at row 11 (and subsequent rows),
as can be seen in the screencast at http://screencast.com/t/bn9QvV0qt
question:
- (q1) How can the repeated rows in scenario (sc1) be explained/avoided?
many thanks
Jan Vervecken

Thanks for your reply Nick Haralabidis.
it can be avoided by setting the EmployeesVO Access Mode to Range Paging and setting the Range Size to 10. Indeed, that does seem to avoid the repeating rows.
Now why you get this behavior when you don't specify Range Paging on the VO I don't know. It could be because: 1) it is a bug - the obvious answer ;) , 2) because setting the RangeSize on the EmployeesVOVIIterator without setting the Access Mode on the EmployeesVO to Range Paging is conflicting - but then again there is no warning or error produced by JDeveloper, 3) ...It does look like unintended behaviour, for a "default approach" like this.
In documentation section "39.1.5 Efficiently Scrolling Through Large Result Sets Using Range Paging " ...
at http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcadvvo.htm#ADFFD1179
... this Range Paging for a View Object seems to be described as an optimization, not as a requirement for functionally correct behaviour.
- about (q1)
Another approach that seems to avoid the repeated rows in scenario (sc1) is removing the value for the RangeSize attribute on the iterator, so the RangeSize is not specified.
Using the modified example application
at http://www.consideringred.com/files/oracle/2010/RepeatedRowsIssueApp-v0.02.zip
... this can be seen in scenario (sc2) in the screencast at http://screencast.com/t/0bpCo33i8J
Although, the documentation in section "22.4.2.2 Iterator RangeSize Attribute " ...
at http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/web_form.htm#ADFFD706
... does not seem to mention anything about not specifying the RangeSize attribute, it does say "... You can set it to -1 to have the full record set returned. ...".
As can be seen in scenario (sc2) the EL expression #{bindings.EmployeesVOVIIterator.rangeSize} resolves to -1 which suggests that not specifying the RangeSize attribute is the same as configuring the RangeSize attribute to -1.
questions:
- (q2) What is the preferred way to avoid having "the full record set returned", without having repeated rows as in scenario (sc1)?
- (q3) Is the default configuration of RangeSize="25" on the iterator intended behaviour (for an interator supporting an executeWithParams action)?
regards
Jan

Update before a report shows with bind variable

I need to update a table before a report shows. This report have bind variable and I need bind variable value for clause where in update, how can I do that?
I would thank so much any idea

Mery,
If I understand correctly your application should display a report when it is called.
But first, before the report is displayed, you want to update a table, using a bind variable passed into the report when it is called. Do I understand correctly so far?
So while editing the report, in the last tab option you have (Additional PL/SQL Code), you need to put some pl/sql code into section titled '...before displaying the page.'
declare
begin
update table_x
set column_x = somevalue
where column_y = bind_variable;
end;
I haven't yet passed bind variables into reports so I'm not quite sure how to retrieve them, but I'm sure there are other postings here about that.
I'm mostly just trying to clarify if this is what your asking, and maybe somebody else can answer the rest of your questions.
Good luck.
Kurt
