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.
Regards,
Frederico.

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.

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.

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

                    BINARY_FLOAT | BINARY_DOUBLE ] ]
The above is the error I get - i cant declare a variable as raw.
SQL> variable b2 RAW(18);

--now the actual query below

(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;

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?

Report Query returning "No Data Found" with bind variables

I put a simple query into Report Query:
Select "bluefish". "name" as "name",
"bluefish"."primary_flag" as "primary_flag",
"bluefish"."status" as "status",
"bluefish"."ID" as "ID" from "bluefish" "bluefish" where "bluefish"."ID" = :P3_XPRINTID
When I test the query, data is returned; however, when I try to run the query using "Test Report" button, I get an error 01403 No Data Found. If I replace the bind variable with an explicit value, the report works.
Anyone have any ideas as to what is causing this problem? I am using the Generic Report Layout, with various output types. I AM editting the query and defining the bind variable before I test the report (otherwise, the query wouldn't run).
Charles

Sometimes if you create a form/report/whatever using the wizards, it will create an After Submit process called something like Reset Page - basically you want to make sure you don't have any After Submit processes that call a Clear Session state (it may say something like Clear Cache for Page).
In your branch, there is also a box that says Clear Cache - you want to make sure that does not have page Number 8 in it or it will clear your session state.
Put the page in Debug mode and read through it - check to make sure your value is getting saved and maybe you can see what is going wrong.

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

Create collection from query with bind variable

Apex 4.0.2
Per Joel Re: Collection with bind variable the apex_collection.create_collection_from_query_b supports queries containing bind variable references (:P1_X) but I am not sure how to use this feature, the documentation doesn't have an example, just the API signature for the overloaded version has changed.

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?
Cheers
Ben

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?

LOV(af:selectOneChoice) with bind variable in af:table

Hi All,
I have a table where a column is defined as dropdown(af:selectOneChoice). The query for selectOneChoice has a bind variable which needs to be set as a value from the base view Object corresponding row.
Suppose a table Employee
EmpId EmpName EmpType Authorization
101 John Temp No
The above table is created as af:table and 'Authorization' is implemented as dropdown(af:selectOneChoice) . The selectOneChoice has a query(AuthorizationLovVVO) with bind variable . For each row of af:table(EmployeeVO) , af:selectOneChoice query(AuthorizationLovVVO) requires
the corresponding row(EmployeeVO) 'EmpType' to be set as value of bind variable.
Can you please suggest how can we achieve this functionality.

I have checked the following post where it has been suggested to access the the current row value as groovy expression.
groovy for bind variable
Suppose my AM name is 'TestAM' , i have tried the below expressions for value of bind variable but it does not work :
1) adf.object.TestAM.findViewObject('EmployeeVO1').currentRow.EmpType
2) adf.object.TestAMDataControl.findViewObject('EmployeeVO1').currentRow.EmpType
None of the above expressions work and i get the error while running the page as 'Variable NotesAM is not recognized.' / 'Variable NotesAMDataControl is not recognized.' .
Can you please suggest if we can achieve the functionality using this approach . Also let me know if i am missing something in the above expression.

How to querie with bind variable in findMode?

Hallo,
is it possible to use a querie with bind variable in findMode? And when how is it possible to initialize the bind variable?
Any help is appreciated.

Hi,
bind variables can be linked from teh ADF binding to e.g. a managed bean, the sessionScope or other binding attributes via EL. So when you go into findMode and execute the query, the EL will grab the bindVariable values automatically.

BC4J bug with "bind variables" JBO-27122 ORA-01008

I think we are found a BUG using BC4J with bind variables in a view object.
If the bind variable appear in the WHERE condition two or more times at
the beginning of the query the above error occur.
oracle.jbo.SQLStmtException: JBO-27122: SQL error during statement preparation. Statement:
SELECT Emp.EMPNO,Emp.ENAME,Emp.JOB,Emp.MGR,Emp.HIREDATE,Emp.SAL,Emp.COMM, Emp.DEPTNO
FROM SCOTT.EMP Emp
WHERE :1 <=10000 and :1 <= sal and :2=20
java.sql.SQLException: ORA-01008: not all variables bound
Otherwise if bind variable apper two or more times, but not together
like this sample:
WHERE :1 <=10000 and :2=20 and :1 <= sal
the error not occur.
We prove this with:
JDeveloper 9.0.5.2 (build 1618)Business Components Version 9.0.5.16.0
JDeveloper 9.0.5.0 (build 1375)Business Components Version 9.0.5.13.52
I looking for a patch! or acceptable workaround.
Tx for your help!
diego.
/* the cliente app */
ApplicationModule am = Configuration.createRootApplicationModule("business_tier.AppModule","AppModuleLocal");
ViewObject vo = am.findViewObject("EmpView");
vo.setWhereClauseParam(0,"100");
vo.setWhereClauseParam(1,"20");
Row emp = vo.first();

This is a known bug (1326006). The workaround is to use:
vo.setWhereClauseParam(0,"100");
vo.setWhereClauseParam(1,"20");
vo.setWhereClauseParam(2,"20");
Hope this helps,

JDev 11.1.2.1 Execute method (with bind variable) before page is displayed

Hi All,
I have a view object with a query that uses a bind variable. I drag the data control onto my .jsf page to create a table. I create a query method on a view scope bean. The query method uses the contents of one of the bean's attributes to set the bind variable for the query:
vo.setNamedWhereClauseParam("CraIdBindVar", sessionBean.getCraId());
I place a button on the page that invokes the query method and it populates the table. This is fine but I don't want the user to have to click on the 'query' button when they navigate to this page. I have found forums that discuss creating an AMImpl.jave method, creating a binding on the page, creating an executable for the binding. This works in that the method is executed before the page is displayed. However, the AMImpl method cannot call sessionBean.getCraid() to get the necessary data item to populate the bind variable.
Is there a way to execute my view scope bean method before the page is displayed? Or perhaps a way for the AMImpl.java method to access the view scope variable?
Thanks, Steve

Steve,
you can drag a method call activity onto the task flow. Then select the new method call activity and open the property inspector. Here you select the method from your bean in the method property. Now you first navigate to this method call activity and then to the page.

How to use ApplicationModuleImpl.createViewObject for VO with bind variable

I need to implement a AM method to create VO instance from a generic VODef with bind variables.
The createViewObject() will trigger the executeQuery of the VO before I can set up the bind variables for the query.
What is the proper way to create view object instance with bind variables?

I am using JDeveloper 11.1.1.2.
I have a ViewObjectA declared with some bind variables which determine what business data to be retrieved at runtime via a service method of the ApplicationModule.
As the ViewObjectA is only referenced internally within ApplicationModule and I need more than one instance of the ViewObjectA for different conditions at runtime,
I use ApplicationModuleImpl.createViewObject() to create an instance of ViewObjectA instead of adding ViewObjectA to the data model of the ApplicationModule.
Currently, when the ViewObjectA is instantiated, it also trigger an executeQuery() which will not retrieve correct data until I set up the bind variables.
However, the createViewObject() method doesn't let me pass in the values of the binding variables.
Currenlty, I just call the createViewObject() and then set the binding variables values and call executeQuery() again.
Just checking if there is a better way to do so...
