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.

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?

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'
                passing xmltype(l_xml)
                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.

How to use session variable in JSP function & How to use both JSP Servlet

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.

How to use bind variable in the query to avoid hard parsing

You dont need Dynamic SQL. Your Table and Column Name are static in that query. Just use Static SQL
SELECT SUMTOTAL
INTO lSumTotal
FROM tab1
WHERE BATCHNO = gBatchNo
   AND ATM_ID = gAtm_id
   AND LOAD_ID = gLoadId
   AND STEP_CODE = 'C_3';

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)

How to use bind variable in this select statement

Hi,
I have created this procedure where table name and fieldname is variable as they vary, therefore i passed them as parameter. This procedure will trim leading (.) if first five char is '.THE''. The procedure performs the required task. I want to make select statement with bind variable is there any possibility to use a bind variable in this select statement.
the procedure is given below:
create or replace procedure test(tablename in varchar2, fieldname IN varchar2)
authid current_user
is
type poicurtype is ref cursor;
poi_cur poicurtype;
sqlst varchar2(250);
THEVALUE NUMBER;
begin
     sqlst:='SELECT EMPNO FROM '||TABLENAME||' WHERE SUBSTR('||FIELDNAME||',1,5)=''.THE ''';
     DBMS_OUTPUT.PUT_LINE(SQLST);
OPEN POI_CUR FOR SQLST ;
LOOP
     FETCH POI_CUR INTO THEVALUE;
          EXIT WHEN POI_CUR%NOTFOUND;
          DBMS_OUTPUT.PUT_LINE(THEVALUE);
          SQLST:='UPDATE '||TABLENAME|| ' SET '||FIELDNAME||'=LTRIM('||FIELDNAME||',''.'')';
          SQLST:=SQLST|| ' WHERE EMPNO=:X';
          DBMS_OUTPUT.PUT_LINE(SQLST);
               EXECUTE IMMEDIATE SQLST USING THEVALUE;
END LOOP;
COMMIT;
END TEST;
Best Regards,

So you want to amend each row individually? Is there some reason you're trying to make this procedure run as slow as possible?
create or replace procedure test (tablename in varchar2, fieldname in varchar2)
authid current_user
is
   sqlst      varchar2 (250);
   thevalue   number := 1234;
begin
   sqlst := 'update ' || tablename || ' set ' || fieldname || '= ltrim(' || fieldname || ',''.'') where substr(' || fieldname
      || ',1,5) = ''.THE ''';
   dbms_output.put_line (sqlst);
   execute immediate sqlst;
end test;will update every row that satisfies the criteria in a single statement. If there are 10 rows that start with '.THE ' then it will update 10 rows.

How to use a variable of jsp custom tag in my java code?

hi folks,
i got a folderList tag like this:
ArrayList list = new ArrayList(20);
%>
<foo:folderList path="${attributes.newsPath}" var="year" contentType="folder">
<%
          list.add(${year.contentEntryName});   // of course, this doesn't work
%>
</foo:folderList>I think, its clear what I want to do. I am just wondering how I can use my Variable "year" in the Java code between <% %>...

<% list.add(year.getContentEntryName()); %>
You have to have defined in the custom tag that "var" relates to a scripting variable that you want defined.
<tag>
<variable>
    <name-given>var</name-given>
    <variable-class>myPackage.myClass</variable-class>
    <declare>true</declare>
    <scope>NESTED</scope>
</variable>
</tag> Cheers,
