Do not use bind variable notations for p_session_id argument...

Hi there,
... in apex_custom_auth.login the Apex doc says. Does anyone know why not?
LOGIN Procedure
Also referred to as the "Login API," this procedure performs authentication and session registration.
p_session_id Current Oracle Application Express session ID.
Note: Do not use bind variable notations for p_session_id argument.Thanks
Luis

I tend to avoid assigning values to bind variables like that - but it may be due to the nature of much of my code residing in PL/SQL packages.
And due to the strange encounters I have had with this, like your linked discussions, I've tended towards using apex_util instead.

How to use bind variable value for table name in select statement.

Hi everyone,
I am having tough time to use value of bind variable for table name in select statement. I tried &p37_table_name. ,
:p37_table_name or v('p37_table_name) but none worked.
Following is the sql for interactive report:
select * from v('p37_table_name') where key_loc = :P37_KEY_LOC and
to_char(inspection_dte,'mm/dd/yyyy') = :P37_INSP_DT AND :p37_column_name is not null ;
I am setting value of p37_table_name in previous page which is atm_state_day_insp.
Following is error msg:
"Query cannot be parsed, please check the syntax of your query. (ORA-00933: SQL command not properly ended) "
Any help would be higly appreciated.

Interestingly enough I always had the same impression that you had to use a function to do this but found out from someone else that all you need to do is change the radio button from Use Query-Specific Column Names and Validate Query to Use Generic Column Names (parse query at runtime only). Apex will substitute your bind variable for you at run-time (something you can't normally do in pl/sql without using dynamic sql)

Query don't use the right index when using bind variables

Hi people !
I need some help because I have an issue with a query that don t use the right Indexes as it should
First of all, I have mainly three tables :
ORDER : Table that contains description for each Order (approximately 1 000 000 Records)
ORDER_MVTS : Table that contains the tasks made (called movements) to set up each Orders
with quantity of packages prepared for each product (approximately 10 000 000 Records)
PRODUCT : Tables that contains the products (approximately 50 000 Records)
When I launch the query with hard coded values, it brings back response very fast
because it uses the right index (ORDER_DHR_VALID) which represent the date and hour of the order
(with format 'DD/MM/YYYY HH24:MI:SS'). The selectivity for this index is good.
NB 1: I have to use the trick " >= Trunc(date) and < trunc(date) +1 " to filter on a simple date because
the index contains hour and minutes (I know it wasn't probably a bright idea at conception time).
NB 2: The index on ORDER_MVTS.PRODUCT_CODE is'nt discriminating enough because there is'nt enough different products.
It's the same for index on CUSTOMER_CODE and on MVT_TYPE so only the index on ORDER.DHR_VALID is good.
Here is the correct explain plan when I execute the query with hard coded values :
SELECT SUM(ORDER_MVTS.NB_PACKAGE)
FROM ORDER_MVTS, PRODUCT, ORDER
WHERE ORDER.DHR_VALID >= TRUNC(to_date('14/11/2008 10:04:56','DD/MM/YYYY HH24:MI:SS'))
AND ORDER.DHR_VALID < TRUNC(to_date('14/11/2008 10:04:56','DD/MM/YYYY HH24:MI:SS')) + 1
AND ORDER_MVTS.MVT_TYPE = 'DELIVERY'
AND PRODUCT.CODE = ORDER_MVTS.PRODUCT_CODE
AND ORDER_MVTS.ORDER_CODE = ORDER.CODE
AND ORDER.CUSTOMER_CODE = 'ADIDAS'
AND PRODUCT.CODE = 1234
Rows Row Source Operation
1 SORT AGGREGATE
2 NESTED LOOPS
4 NESTED LOOPS
2 INDEX UNIQUE SCAN (object id 378548) --> PRODUCT_PK
4 TABLE ACCESS BY INDEX ROWID ORDER
777 INDEX RANGE SCAN (object id 378119) --> ORDER_DHR_VALID
2 TABLE ACCESS BY INDEX ROWID ORDER_MVTS
30 INDEX RANGE SCAN (object id 377784) --> ORDER_MVTS_ORDER_FK
Now the problem is when the query is used in a Cursor with bind variables.
It seems like Oracle don't use index on ORDER.DHR_VALID because he can't figure out that he have
to actually filter on a short period of time (only one day).
So Oracle uses the index on ORDER_MVTS.PRODUCT_CODE which is'nt a bright idea (it takes 10 secondes instead of just one)
Here is the bad explain plan :
Rows Row Source Operation
1 SORT AGGREGATE
2 NESTED LOOPS
722 NESTED LOOPS
2 INDEX UNIQUE SCAN (object id 378548) --> PRODUCT_PK
722 TABLE ACCESS BY INDEX ROWID ORDER_MVTS
1790 INDEX RANGE SCAN (object id 377777) --> ORDER_MVTS_PRODUCT_FK
2 TABLE ACCESS BY INDEX ROWID ORDER
1442 INDEX UNIQUE SCAN (object id 378439) --> ORDER_PK
Now I have found two solutions to this problem :
1) using a Hint to force the use of index on ORDER.DHR_VALID (with /*+ INDEX(ORDER ORDER_DHR_VALID) */ )
2) Using Dynamic SQL and keeping the date hard coded (but not the other values except mvt_type)
For example :
QUERY :=
'SELECT SUM(ORDER_MVTS.NB_PACKAGE)
FROM ORDER_MVTS, PRODUCT, ORDER
WHERE ORDER.DHR_VALID >= TRUNC(TO_DATE('''||To_char(P_DTE_VAL,'DD/MM/YYYY')||''',''DD/MM/YYYY'')) '||
AND ORDER.DHR_VALID < TRUNC(TO_DATE('''||To_char(P_DTE_VAL,'DD/MM/YYYY')||''',''DD/MM/YYYY'')) + 1 '||
AND ORDER_MVTS.MVT_TYPE = 'DELIVERY'
AND PRODUCT.CODE = ORDER_MVTS.PRODUCT_CODE
AND ORDER_MVTS.ORDER_CODE = ORDER.CODE
AND ORDER.CUSTOMER_CODE = :CUSTOMER
AND PRODUCT.CODE = :CODE ';
These two solutions work but Number 1 is bad in theory because it uses a Hint
and Number 2 may be difficult to code.
So my question is : Does someone knows another solution to force the use of index ORDER_DHR_VALID that can be simple and reliable.
Thank you very much for support

What version of oracle you have? CBO work is different in 9i and 10g.
Usually cost based optimizer do not want to use index for >< condition with binding variables because optimizer can not use statistic to determine selectivity, and by default selectivity of <> operators is low.
(As I remember '>' selectivity by default is 5%, you have two conditions > and <, therefore resulting selectivity will be 0.05*0.05=0.0025 as two independent events, but selectivity of other conditions
ORDER_MVTS.MVT_TYPE = 'DELIVERY' or ORDER.CUSTOMER_CODE = 'ADIDAS' looks much better for CBO)
The best solution I see is do not use binding variables. Actually your query looks as searching query, which executes not so often, therefore you will not have perfomance win along of skipping execution plan creation.

Performance when using bind variables

I'm trying to show myself that bind variables improve performance (I believe it, I just want to see it).
I've created a simple table of 100,000 records each row a single column of type integer. I populate it with a number between 1 and 100,000
Now, with a JAVA program I delete 2,000 of the records by performing a loop and using the loop counter in my where predicate.
My first JAVA program runs without using bind variables as follows:
loop
stmt.executeUpdate("delete from nobind_test where id = " + i);
end loop
My second JAVA program uses bind variables as follows:
pstmt = conn.prepareStatement("delete from bind_test where id = ?");
loop
pstmt.setString(1, String.valueof(i));
rs = pstmt.executeQuery();
end loop;
Monitoring of v$SQL shows that program one doesn't use bind variables, and program two does use bind variables.
The trouble is that the program that does not use bind variables runs faster than the bind variable program.
Can anyone tell me why this would be? Is my test too simple?
Thanks.

The point is that you have to find out where your test is spending most of the time.
If you've just populated a table with 100,000 records and then start to delete randomly 2,000 of them, the database has to perform a full table scan for each of the records to be deleted.
So probably most of the time is spent scanning the table over and over again, although most of blocks might already be in your database buffer cache.
The difference between the hard parse and the soft parse of such a simple statement might be negligible compared to effort it takes to fulfill each delete execution.
You might want to change the setup of your test: Add a primary key constraint to your test table and delete the rows using this primary key as predicate. Then the time it takes to locate the row to delete should be negligible compared to the hard parse / soft parse difference.
You probably need to increase your iteration count because deleting 2,000 records this way probably takes too short and introduces measuring issues. Try to delete more rows, then you should be able to spot a significant and constant difference between the two approaches.
In order to prevent any performance issues from a potentially degenerated index due to numerous DML activities, you could also just change your test case to query for a particular column of the row corresponding to your predicate rather than deleting it.

How to use bind variables in this procedure

Hi Experts,
How to use bind variables in this procedure for static queries.
PROCEDURE DELETE_MER_PROC (M_id IN NUMBER)

V_date DATE;

How to use v_date and m_id as bind variables in this procedure to avoid hard parsing.
Please help me.
Thanks.

You cannot avoid hard parsing - as the 1st time a SQL statement (like the SELECT or DELETE statements in your code) is encountered, it does not reside in the server's Shared Pool, and needs to be added into the pool via a hard parse.
Bind variables does not prevent hard parsing. Hard parsing happens when the SQL statement (with or without bind variables) is a brand new statement encountered by the server.
Bind variables enables the same SQL cursor to be reused, by simply changing the bind variable value.
Not using bind variables means that each SQL statement is unique and not shareable - as the value is hardcoded into the statement and cannot be changed via a bind value. This typically means LOTS of different SQL statements (where the only difference is the changed value in the statement) are created - with each statement being a new statement not seen before in the Shared Pool and needing to be hard parsed.
One does not design one's code not to be hard parsed. There ALWAYS will be a hard parse in order to get a SQL statement into the Shared Pool. One designs one's code to REUSE cursors in the Shared Pool.

ORA-01006 Using Bind Variables In A Dynamic SQL Contains Query

I have the following dynamic SQL query :-
declare
TYPE typ_sql IS REF CURSOR;
ltyp_sql typ_sql;
lv_sql VARCHAR2(100);
begin
lv_sql := 'SELECT arx_id FROM arx WHERE CONTAINS ';
lv_sql := lv_sql || (arx_full,''(:b1) WITHIN ui'') > 0';
open ltyp_sql FOR v_sql USING ln_id;
fetch ......
close ......
end;
When the code tries to open the cursor it gives the above error. I presume it is the way Oracle is expanding the bind variable but I cannot find anything in the docs to say why this is happening or whether you can do this or not using bind variables ( CONTAINS query ). Any help would be appreciated, thanks,
Stuart.

lv_sql || '(arx_full, :b1 || '' within ui'') > 0';

How to use bind variables in desc flexfields in OA pages?

Use case: In EBS 11i we have a DFF on po_vendors and one of the segment has a table validated value set that is referencing a forms variable i.e :VENDORS.VENDOR_ID. Now after upgrading to R12 this won't work as the vendor pages moved to OA framework. Is there any way to reference the vendor_id column in OA framework?

Possible for Oracle to consider constraints when using bind variable?

Consider the following table with a check constraint listing the possible values of the column
create table TEST_TABLE(
my_column varchar2(10));
insert into TEST_TABLE select 'VALUE1' from dba_objects;
alter table TEST_TABLE
add constraint TEST_TABLE_CHK1
check (my_column in ('VALUE1', 'VALUE2'));
begin dbms_stats.gather_table_stats(ownname=>user,tabname=>'TEST_TABLE');END;Let's see the number of logical I/O's needed for the following SQL statements.
(The value was obtained by the delta ofselect m.value from v$mystat m, v$statname n
where name='session logical reads' and m.statistic#=n.statistic#)
If string lateral is used:
declare
   n number;
begin
select count(*) into n from test_table where my_column='VALUE1';
end;
Consistent Gets: 21
declare
   n number;
begin
select count(*) into n from test_table where my_column='VALUE2';
end;
Consistent Gets: 21
declare
   n number;
begin
select count(*) into n from test_table where my_column='VALUE3';
end;
Consistent Gets: 0Oracle can eliminate the table if it knows the queried value can't satisfy the constraint. Good.
(Actually, the execution plan for the last query included the 'FILTER' operation.)
However, if bind variable is used:
declare
   n number;
   x varchar2(10);
begin
x := 'VALUE1';
select count(*) into n from test_table where my_column=x;
end;
Consistent Gets: 21
declare
   n number;
   x varchar2(10);
begin
x := 'VALUE3';
select count(*) into n from test_table where my_column=x;
end;
Consistent Gets: 21Oracle can't eliminate the table using the constraint. I can understand that because bind variables are used, Oracle can't directly eliminate the table when generating the execution plan. However, is it possible to eliminate the table, or at least employ some shortcut in runtime? If not, will this be a performance loss compared with using values laterals when check constraint exists?
(And is it possible to use autotrace on PL/SQL block in sqlplus?)
Oracle:
     10.2.0.4 SE
     11.2.0.2 SE
OS:
     RHEL5

However, is it possible to eliminate the table, or at least employ some shortcut in runtime? I can't see how to do this. Oracle has a sqltext that has an embedded bind variable in it. And for this sqltext it has an execution plan in the shared pool that will be used irrespective of the actual bound values at runtime.
Maybe in 11G, with adaptive cursor sharing / plan bind awareness, Oracle might be smart enough to introduce a second execution plan for the VALUE3 case.
If not, will this be a performance loss compared with using values laterals when check constraint exists?Only if you submit the dumb query and search for records with VALUE3... Normally your application code would not hold/generate these queries.
Will it?
For columns whose values are bound by a CHECK constraint, one might even consider to never use bind variables, since very likely you will have few versions of queries that use these columns.
Not?

How to use bind variable value of one VO as initial value for other VO row?

JDeveloper 10.1.3.3, ADF Faces, ADF BC
Hi,
I have two View Objects: one read only with several bound variables and another editable entity based. Correspondingly there are two ADF Faces pages: first contains search form based on the read-only VO and second create form based on the editable VO. The search form has several hidden fields for some of bound variables because they aren't edited directly by user. These fields are updated with PPR when user selects other search criteria from LOV.
There is a command button in the first page that navigates to the second form. Is there any way to transfer values of bound variables from the first VO to the second VO as initial values of the new row?
I tried to set custom controller for the second page and retrieve search criteria values from request parameter map but values from hidden fields are missing. I think because that these fields are updated by PPR. Of course I can add custom action method to the navigation button and in the method put these values to request parameter map but I hope there is better solution.
Thanks,
Marius

To summarize, given a bind variable value for one VO, on creating a row in a second VO, for 1 of the attributes of the second VO, you want to use the first VO's bind variable value. Correct?
A potential solution ADF BC driven:
1) Ensure you have an AppModuleImpl for your AM
2) Ensure you have a ViewImpl for your 1st VO (where the bind variable will exist) - lets refer to that VO as "Alpha"
3) Ensure you have a ViewRowImpl for your 2nd VO (the one you want to default the value in) - lets refer to that VO as "Beta"
4) For your first VO "Alpha" create the bind variable (say pValue)
5) In your second VO "Beta" ViewRomImpl add following code:
@Override
protected void create(AttributeList attributeList) {
super.create(attributeList);
AppModuleImpl am = (AppModuleImpl)this.getApplicationModule();
String someValue = am.getAlphaView1().getpValue();
setSecondVOAttr(someValue); // change this code to whatever your setter is for the field you want to initialize.
}Hope this helps. Let us know how you go.

CM.

Trying to pass array to stored procedure in a loop using bind variable

All,
I'm having trouble figuring out if I can do the following:
I have a stored procedure as follows:
create procedure enque_f826_utility_q (inpayload IN f826_utility_payload, msgid out RAW) is
enqopt dbms_aq.enqueue_options_t;
mprop dbms_aq.message_properties_t;
begin
dbms_aq.enqueue(queue_name=>'f826_utility_queue',
enqueue_options=>enqopt,
message_properties=>mprop,
payload=>inpayload,
msgid=>msgid);
end;
The above compiles cleanly.
The first parameter "inpayload" a database type something like the following:
create or replace type f826_utility_payload as object
2 (
3 YEAR NUMBER(4,0),
4 MONTH NUMBER(2,0),
83 MUSTHAVE CHAR(1)
84 );
I'd like to call the stored procedure enque_f826_utility_q in a loop passing to it
each time, new values in the inpayload parameter.
My questions are:
First, I'm not sure in php, how to construct the first parameter which is a database type.
Can I just make an associative array variable with the keys of the array the same as the columns of the database type shown above and then pass that array to the stored procedure?
Second, is it possible to parse a statement that calls the enque_f826_utility_q procedure using bind variables and then execute the call to the stored procedure in a loop passing new bind variables each time?
I've tried something like the following but it's not working:
$conn = oci_pconnect (....);
$stmt = "select * from f826_utility";
$stid = oci_parse($conn, $sqlstmt);
$r = oci_execute($stid, OCI_DEFAULT);
$row = array();
$msgid = "";
$enqstmt = "call enque_f826_utility_q(:RID,:MID)";
$enqstid = oci_parse($conn, $sqlstmt);
oci_bind_by_name($enqstid, ":RID", $row); /* line 57 */
oci_bind_by_name($enqstid, ":MID", $msgid);
while ($row = oci_fetch_array($stid, OCI_RETURN_NULLS+OCI_ASSOC))
++$rowcnt;
if (! oci_execute($enqstid)) /* line 65 */
echo "Error";
exit;
When I run this, I get the following:
PHP Notice: Array to string conversion in C:\Temp\enqueue_f826_utility.php on l
ine 57
Entering loop to process records from F826_UTIITY table
PHP Notice: Array to string conversion in C:\Temp\enqueue_f826_utility.php on l

e 65
PHP Notice: Undefined variable: msgnum in C:\Temp\enqueue_f826_utility.php on l
ine 68

Exiting!

Thanks for the reply.
I took a look at this article. What it appears to describe is
a calling a stored procedure that takes a collection type which is an array.
Does anyone from Oracle know if I can pass other database type definitions to a stored procedure from PHP?
I have a type defined in my database similar to the following which is not
an array but a record of various fields. This type corresponds to a payload
of an advanced queue payload type. I have a stored procedure which will take as it's input, a payload type of this structure and then enqueue it to a queue.
So I want to be able to pass a database type similar to the following type definition from within PHP. Can anyone from Oracle verify whether or not this is possible?
create or replace type f826_utility_payload as object
YEAR NUMBER(4,0),
MONTH NUMBER(2,0),
UTILITY_ID NUMBER(10,0),
SUBMIT_FAIL_BY VARCHAR2(30),
MUSTHAVE CHAR(1)
);

Why are you using dynamic SQL statements? Why not just use something like this instead in your PL/SQL. I also replaced the leading // in your Xpath with just / since you start from the root node.
select *
INTO l_dummy
from xmltable(XMLNAMESPACES('http://www.w3.org/2001/XMLSchema' AS "XSD", default 'http://schemas.xmlsoap.org/wsdl/'),
                '/definitions/types/XSD:schema/XSD:element'

                columns
                ab xmltype path '.' ) t;Also, the above returns two rows, which I suspect is not what you want. Here is the pure SQL version for you to debug.

ORA-01722: invalid number caused with SQL using bind variable

Hi,
Im am hoping that someone can help me resolve a problem thats only just services and is being experienced on quite a few clients.
our application uses C++ exes and makes OCI calls to the database.
what has happened in the last week or so, there has been quite a few invalid number errors being received on a prod server but strangly enough we cannot reproduct the error on our UAT system.
The sql is using bind variables and the information in the trace file shows that a number is being used for the bind variable, here is an extract from one trace file:
for some schemas, the bind variable value is some currupted value, i think:
oacdty=01 mxl=32(21) mxlc=00 mal=00 scl=00 pre=00
oacflg=03 fl2=1206001 frm=01 csi=178 siz=32 off=0
kxsbbbfp=9a8d62b8 bln=32 avl=03 flg=05
value="Â*d"
but on another schema, the value used is:
Bind#0
oacdty=01 mxl=32(32) mxlc=00 mal=00 scl=00 pre=00
oacflg=03 fl2=1206001 frm=01 csi=178 siz=32 off=0
kxsbbbfp=c5f92718 bln=32 avl=04 flg=05
value="2101"
however both produce invalid number errors.
I am relatively inexperienced as a DBA so would appreciate as much help as i can get.

Could you post your sql statement that is being run.
Also post the query plan from your uat system and the one from your production system (They are likely to be different)
You can export the stats from your production system and run them in your uat system. If you do this, then the execution plans should be the same on both systems(dbms_stats) and if you have the same data you should run into the same problem on uat as in production.
The root cause of this type of problem is having a column in a table which holds values which are of different datatypes. Typically there is a condition in the where clause which indicates that for example only numeric columns should be retrieved from the column which holds multiple data types. However since the optimizer is free to rewrite the query any way it sees fit, (It does not necessarily execute in the order the sql statement is written) it does not filter this data first, and therefore you hit non-numeric data and run into the invalid number error.
You can use little techniques like using an inline view with rownum in the column list, to perform the first filter. This ensures that the inline view is executed on its own, rather than being merged (materialized) with the rest of the query.
A quick temporary solution is to use a comparison like to_char(column_name) = variable
Make sure your comparisons are correct and it doesn't negatively impact on performance of the query

Using Bind variables in SQL PLUS Report

using Bind variables in SQL PLUS Report. This report gets the arguments from the application concurrent program. Now my need is to convert the start_date and end_date to bind Variables to improve the performance. I have commented the original code in 'prompt List of Unapproved Adjustments' and used my Bind Variable but it is giving an error

Hi
Please go to customization part of the report and verify..You have set a default value out there ..And also verify your lov and look at the values ..If it is again giving you the problem ..pl delete the report and develop it again from the scratch it will be solved...

How to use bind variable

Hi,
I have the below cursor 1 which is working already.For my requirement i want to use bind variable like second cursor.But its telling Bind Variable "p_col_list" is NOT DECLARED.Please any onehelp me on this.
How to use bind variable Here.
Cursor1:
DECLARE
emp_cv sys_refcursor;
iid NUMBER := 1;
i_sql varchar2(100);
p_col_list varchar2(2000) := 'aaa,bbb,ccc,ddd';
BEGIN
i_sql := 'select '''||REPLACE(p_col_list, ',', ''',''')||''' from dual '||CHR(10) ;
dbms_output.put_line(i_sql);
OPEN emp_cv FOR i_sql ;
END;
Cursor2:
DECLARE
emp_cv sys_refcursor;
iid NUMBER := 1;
i_sql varchar2(100);
p_col_list varchar2(2000) := 'aaa,bbb,ccc,ddd';
BEGIN
i_sql := 'select '''||REPLACE(:p_col_list, ',', ''',''')||''' from dual '||CHR(10) ;
dbms_output.put_line(i_sql);
OPEN emp_cv FOR i_sql using p_col_list;
END;

hello,
the reports parameterform capabilities are limited. if you want
to create sophisticated parameterforms, you should do that with
oracle forms or html forms.

BUG ? : ADF creating extra VO instance using bind variables in a LOV query

ADF 11.1.1.1.0
After "playing around" with bind variables Setting bind variables in view objects for LOV I've come across something strange that I've reproduce using the HR schema and tables Employees and Departments. Its a bit long but here goes :
Using the HR schema tables departments and employeesI'm trying to create a LOV (selectOneChoice) for the
employee department, the LOV having a bind variable that limits the values returned in this case returning only DepartmentId = 50
I've create a VO lovDepartment (not based on an EO) with the following query :
SELECT Departments.DEPARTMENT_ID,
       Departments.DEPARTMENT_NAME,
       Departments.MANAGER_ID,
       Departments.LOCATION_ID
FROM DEPARTMENTS Departments
where DEPARTMENT_ID = :pDeptIdA LOV has been defined on the DepartmentId attribute of the EmployeesView.
The lovDepartmentImpl overrides the executeQueryForCollection to set the bind variable value.
    @Override
    protected void executeQueryForCollection(Object object, Object[] object2,
                                             int i) {
        setNamedWhereClauseParam("pDeptId", "50");
        super.executeQueryForCollection(object, object2, i);
    }When using an ADF form to create a new employee the DepartmentId lov is empty.
Enabling SQL tracing shows the following :
[370] _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1_0 ViewRowSetImpl.doSetWhereClause(-1, pDeptId, null)
[371] _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1_0 ViewRowSetImpl.execute caused params to be "un"changed
[372] Column count: 4
[373] _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1_0 ViewRowSetImpl.doSetWhereClause(-1, pDeptId, null)
[374] _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1 ViewRowSetImpl.setNamedWhereClauseParam(pDeptId, 50)
[375] ViewObject: _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1 Created new QUERY statement
[376] _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1>#q computed SQLStmtBufLen: 235, actual=195, storing=225
[377] SELECT Departments.DEPARTMENT_ID,
       Departments.DEPARTMENT_NAME,
       Departments.MANAGER_ID,
       Departments.LOCATION_ID
FROM DEPARTMENTS Departments
where DEPARTMENT_ID = :pDeptId
[378] Bind params for ViewObject: _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1
[379] For RowSet : _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1_0
[380] Binding null of type 12 for "pDeptId"
[381] No Resource Bundle found but null value id:LOV_DepartmentId_LOVUIHints_NullValueId is defined in an ListBinding Definition.It would seem that 2 lovDepartment instances are used one at line 370 LOCALVIEW_USAGE_model_EmployeesView_lovDepartment1_0
and one at line 374 LOCALVIEW_USAGE_model_EmployeesView_lovDepartment1
The one at line 374 LOCALVIEW_USAGE_model_EmployeesView_lovDepartment1 gets the variable bound at line 374
however LOCALVIEW_USAGE_model_EmployeesView_lovDepartment1_0 gets a null value and would explain the empty LOV
Can anybody explain what is happening here ? (and how to use bind variables in LOV queries)
Regards
Paul

I've now tried all types of LOV from ChoiceList to Radio groupe by testing the application module - none of them work.....

when you rinvoke executeQueryForCollection the bind variables are allready set and they exist in Object[] object2 method parameters.
in order to change them you need something like:
private void changeGenericBindVariable(Object[] params, String paramName, Object paramValue) {
for (int i = 0; i < params.length; i++) {
if (paramName.equals(((Object[])params)[0].toString()))
((Object[])params[i])[1] = paramValue;
* executeQueryForCollection - overridden for custom java data source support.
protected void executeQueryForCollection(Object qc, Object[] params,
int noUserParams) {
changeGenericBindVariable(params, "pDeptId", "50")
super.executeQueryForCollection(object, object2, i);
But its better to set bind variables before you executeQueryForCollection. like when you invoke LOV.
For cascading LOVs and the problems i have check:

Do not use bind variable notations for p_session_id argument...
