Dynamic query in timecard using LOV or CHOICE_LIST???

Hi
I want to use a dynamic query for custom Project and Task.
E.g. Once a project is selected form Project CHOICE_LIST, the task CHOICE_LIST should show only the tasks related to that particular project.
I have created CHOICE_LIST field for Project and Task.
Is it possible to achieve this using CHOICE_LIST or I will need to define VO?

DYNAMIC QUERY FOR INSERT USING SELECT

Hi All,
I am facing an issue...I am un bale to do an dynamic query. i have explained my code and the sample create, insert statements. I shud insert values in a table using a select statement dynamically..
create table listing (tel_no varchar2(16), list_key varchar2(30));
create table dummy_extract ( extract_name varchar2(10),extract_query varchar2(400),extract_date date );
create table dummy_query (tel_no varchar2(16), list_key varchar2(30));
insert into listing (tel_no ,header_key) values ('123456','123.23');
insert into dummy_extract (extract_name,extract_query,extract_date) values ('SP','SELECT TEL_NO, LIST_KEY FROM LISTING','10-DEC-2010');

Hi Blue shadow and Saubik,
I tried my query.It shows missing expression...Could you tell me the reason...

Dynamic query table for report based on LOV selected

Hi,
Need some suggestion and guidance how to dynamically query table via lov for report .
Scenario:
Table, TABLE_LIST, has tablename (table in DB) and filter (for where clause) column. The TABLENAME_LOVE is derived from table TABLE_LIST.
SELECT TABLENAME D, TABLENAME R FROM TABLE_LIST
In Page 2,a page select list item,P2_TABLENAME to use TABLENAME_LOV
All data in tables in the table_list have identical structure (columns, triggers, primary key, and so on).
I want to have the report region query from the table based on selected LOV.
Example,
Tablename Filter
TB1
CD2 ACTIVE='Y'
When select TB1, the report regin will query based on TB1.
When select CD2, the report regin will query based on CD2 WHERE ACTIVE='Y'
Question:
How can I query based on &P2_TABLENAME. WHERE &P2_FILTER.
Like
select col1, col2 from &P2_TABLENAME WHERE &P2FILTER
Greatly appreciate any suggestion and some guidance.

Hi,
You should always post your Apex version, DB version and other information as suggested in the FAQ.
And the moment you talk report you should state whether it is IR or Classic.
As for your query, have you explored the Report type "SQL Query (PL/SQL function body returning SQL query)" ?
That might be a good fit for what you are trying to achieve.

How to create an LOV based on a dynamic query

Hi,
Can someone tell me how to query a dynamic query for LOV. On my base page I have a dropdown-box (that will show the table names for searching) and is dynamically populated based on users access e.g. if user A logs in he may see 5 values (these values are basically table names) in a drop down if user B logs in he may see 10 values. I also have two input fields one field a user can enter value and the other field is read only and a torch icon for LOV so the user can search and select values that are populated in the input fields on the base page.
How can I have my LOV that takes in a value selected in the dropdown and anyvalue entered in one of the input fields and search in the table selected in the dropdown box.
Basically my LOV should do a search on the table and some search value passed when clicking on the torch icon. So a user can select any table-name in the drop down and my LOV should do a search only on the selected table. Once on the LOV Popup want to have a search field there but it only searched on the table selected in the dropdown on the based page. And the selected value on the LOV Popup page gets populated in fields on the base page.
Any help is appreciated.
Thanks

How to get max date in variable using dynamic query

Hi,
the following code gets all dates from sourcetable i want only max date , so i thought max function can be added and it will work
but still i have to create a table for one value(scalar) can get it in any other effeciant way.
declare
TYPE date_string IS TABLE OF VARCHAR(1000);
date_obj date_string;
BEGIN
EXECUTE IMMEDIATE 'SELECT to_char('''||day1||'-'||month1||'-'||year1||''') FROM '||source_schema||'.'|| sourcetable ||'' bulk collect INTO date_obj;
FOR indx IN date_obj.FIRST..date_obj.LAST loop
dbms_output.put_line(
date_obj(indx));
END loop;
DBMS_OUTPUT.PUT_LINE('Sample output');
END;
yours sincerely

the following code gets all dates from sourcetableNo it doesn't. What is the datatype of day1, month1 and year1? They cannot be DATE datatypes otherwise your TO_CHAR would fail with all that concatenation going on. And your TO_CHAR is returning a VARCHAR2 datatype... so you cannot say that it is getting all dates... because there are no DATE datatypes returned. It's getting a lot of strings, but certainly not DATE's.
i want only max date , so i thought max function can be added and it will work You can use the MAX function on a DATE datatype, but not on strings (at least not in the way you intend it to work).
Converting it to a DATE before doing the MAX will allow you to get the maximum date (assuming the date format is correct)
EXECUTE IMMEDIATE 'SELECT max(to_date(to_char('''||day1||'-'||month1||'-'||year1||'''),''DD-MM-YYYY'')) FROM '||source_schema||'.'|| sourcetable ||'' bulk collect INTO date_obj;Then you will find have the other issues...
a) you are then going to be fetching your DATEs in to a collection of VARCHAR strings. (Not even VARCHAR2, very poor). This should be DATE datatype
b) you are bulk collecting into a collection, when you are using MAX which will return a single value in your example
And you really should address the design issues:
c) why are day, month and year, not being stored in the database as a single DATE datatype in the first place
d) why does your code not know the name of the table it's querying requiring the use of very poor dynamic SQL techniques.
e) why are you loading data in a collection in expensive PGA memory... what can't you do in SQL that requires you to collect the data into memory first?

How to use dynamic query for Result table

Hello Experts,
I want to use dynamic query and then display the result in the assignment block.
Using dynamic query BTQAct and BTQRAct and base on some search criteria i want tofilter and then append the result in the result table of that custom context node, and then it should display the result in the view in UI.
SO can you please provide me the samplle code on how to use the dynamic query and append in the result table.
Regards.

Hi,
Please find below sample code:
data: query         TYPE REF TO cl_crm_bol_dquery_service,
           result        TYPE REF TO if_bol_bo_col.
DATA: lt_params       TYPE crmt_name_value_pair_tab,
           lwa_params      TYPE crmt_name_value_pair.
query = cl_crm_bol_dquery_service=>get_instance( 'BTQAct' ). " Get instance of dynamic query
Set general query parameter for maximum number of hits
      lwa_params-name = 'MAX_HITS' .
      lwa_params-value = '50'.
      APPEND lwa_params TO lt_params.
      query->set_query_parameters( it_parameters = lt_params ).
      query->add_selection_param( iv_attr_name = 'OBJECT_ID'
                                                iv_sign      = 'I'
                                                iv_option    = 'EQ'
                                                iv_low       = <lv_objectid>
                                                iv_high      = '' ). " Set your search criteria. Repeat this code if you have multiple parameters
"You can find possible search options for a query object in GENIL_BOL_BROWSER
result ?= query->get_query_result( ).   " Get result from your search query
me->typed_context-> <your result context node>->set_collection( result ).
Here you will have to create a context node in your view which would refer to query result object like for BTQAct its BTQRAct
Hope this helps.

Help! Inaccessible iterator when using dynamic query

Hi!
I have a problem retreiving results from a dynamic query into sqlj iterator.
I consulted the Oracle App Dev Guide and Oracle SQLJ Dev Guide and wrote the following code:
<PRE>
package pmServer;
#sql iterator LocIterator (int id, String name);
public class pmRISDImpl
public int GetLocations(...)
LocIterator locIt;
String q = "select ID, NAME from PMADM.LOCATIONS";
#sql
BEGIN
open :OUT locIt for :q;
END;
</PRE>
When I try to compile it using tools provided by JDeveloper ver 3.2.2.(Build 915) for JDK 1.2.2 I get error for #sql statement:
Inaccessible Java type for host item locIt (at position #1): pmServer.LocIterator
and warning:
Type pmServer.LocIterator of host item locIt (at position #1) is not permitted in JDBC. This will not be portable.
Althow the code is identcal to those demonstrated in Oracle document "Oracle8 i
SQLJ Developers Guide and Reference
Release 3 (8.1.7)

// build up query as Java string
String query = "select ename, sal from emp " +
(((what_cond == null) | | (what_cond.equals(""))) ? "" :
(" where " + what_cond)) +
"order by ename";
#sql {
begin
open :OUT empIter for -- opening ref cursor with dynamic query
:query;
-- can have USING clause here if needed
end;
while (empIter.next()) {
System.out.println("Employee " + empIter.ename() +
" has salary " + empIter.sal() );
empIter.close();
</PRE>
Please guide me what should I do to get it working.

In the CAST statement the SQLJ runtime must be able to produce an instance of you SQLJ iterator using Java reflection.
This necessitates that the iterator class must be accessible by public.
You have two options:
(1) Declare the iterator public. This requires that you put it in its own file LocIterator.sqlj:
#sql public iterator LocIterator (int id, String name);
(2) Declare the iterator as an inner class. In this case you want to make it public static (that is it does not require an instance of the outer class in scope). You might write the following.
package pmServer;
public class pmRISDImpl
#sql public static iterator LocIterator (int id, String name);
(3) If you are using Oracle 9i you have another option. You can embed dynamic SQL fragments directly in your SQLJ code and do not need to use the CAST:
public int GetLocations(...)
LocIterator locIt;
String q = "PMADM.LOCATIONS";
#sql locIt = { select ID, NAME from :{q} }; // Note new syntax :{q} for embedding SQL source code
}

Ref Cursor Using Dynamic Query

Hi,
I need to use the ref cursor to fetch result from dynamic query.
e.g.
Open ref_test_tbl for Select * from tbl1 where tbl1.field1= :1
and tbl1.field2 =:2 using i_v1,i_v2;
The thing is i_v1, i_v2 are dynamic.
i.e. using clause can include i_v3, i_v4 also.
How to include dynamic variables in the using clause.
thanks

> How to include dynamic variables in the using clause.
Cannot using a ref cursor.. (and anyone that post code that writes dynamic PL/SQL in order to achieve this, I will call an idiot).
What you should be using in PL/SQL is a DBMS_SQL cursor. This allows you to create a fully dynamic SQL statement with bind variables. E.g.
select * from tbl1 where col1 = :1
select * from tbl1 where col2 = :1 order by 2
select * from tbl1 where col3 between :0 and :1
Using this dynamically created SQL statement, you can parse it using DBMS_SQL, determine the number of bind variables, and bind each of these dynamically.
You can then execute the SQL and again, dynamically, determine just what the projection of the cursor is. How many columns are returned, their names, data types, precision and so on.
This is what APEX (see http://apex.oracle.com) use extensively in order to run SQLs and render these as reports - all dynamically.
DBMS_SQL is detailed in the [url http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_sql.htm#BABEDAHF]Oracle® Database PL/SQL Packages and Types Reference manual.

How to use three part name with using dynamic query.

Dear all, (sqlserver 2008 express r2)
q1)following is showing error, is it possible to accomplish the task with out using dynamic query.
DECLARE @A VARCHAR(100)
DECLARE @A1 VARCHAR(100)
SET @A='DB1'
SET @A1='DBO'
SELECT * FROM @[email protected]
q2) table value function is not accepting dynamic query , is there any way to do this task.
yours sincerley

Certain parts in an SQL query like FROM tablename cannot be local variables. In such a case, dynamic SQL can be applied:

As noted above, more information needed to decide if dynamic SQL the correct solution in this instance.

Create table problem using Dynamic Query

Hi all,
I want to create a temporary table within a stored procedure so I decided to do it using a dynamic query:
create or replace procedure p1
as
begin
execute immediate 'CREATE GLOBAL TEMPORARY TABLE tt(id number(2))';
end;
/ It created successfuly but when I execute that procedure I got:SQL> exec p1;
BEGIN p1; END;
ERROR at line 1:
ORA-01031: insufficient privileges
ORA-06512: at "SCOTT.P1", line 4
ORA-06512: at line 1 While I can create that table using the same user without any problem!
My question is:What privilege should I grant to user(minimum of privileges please! ) to execute that procedure successfuly?
-Thanks

Hi,
To say a little bit more about Nicolas' answer:
SQL> grant create table to scott;
This is the right answer, but you might wonder why you have to do so if you usually can create tables with this user..
11:59:19 TEST.SQL>CREATE USER UTEST
11:59:28   2 IDENTIFIED BY UTEST;
User created.
11:59:35 TEST.SQL>CREATE ROLE RTEST;
Role created.
11:59:40 TEST.SQL>GRANT RTEST TO UTEST;
Grant succeeded.
11:59:45 TEST.SQL>GRANT CREATE SESSION TO RTEST;
Grant succeeded.
11:59:54 TEST.SQL>GRANT CREATE TABLE TO RTEST;
Grant succeeded.
12:00:03 TEST.SQL>GRANT UNLIMITED TABLESPACE TO UTEST;
Grant succeeded.

Using Dynamic Query in For Loop

I have a doubt whether i can use the result from dynamic query in the for loop.
for example,
declare
v_sql varchar2(1000);
v_Id INTEGER;
begin
v_sql := 'select id from table1 where id in ('||v_Id||')';
FOR i in vsql LOOP
dbms_output.put_line(i.id);
end loop;
end;
The above query is possible ?

And here's a basic example of opening up a cursor for your dynamic query...
SQL> ed
Wrote file afiedt.buf
1 declare
2    v_sql varchar2(2000);
3    v_cur sys_refcursor;
4    i     emp.sal%type;
5 begin
6    v_sql := 'select sal from emp';
7    open v_cur for v_sql;
8    loop
9      fetch v_cur into i;
10      exit when v_cur%NOTFOUND;
11      dbms_output.put_line('Salary: '||i);
12    end loop;
13* end;
SQL> /
Salary: 800
Salary: 1600
Salary: 1250
Salary: 2975
Salary: 1250
Salary: 2850
Salary: 2450
Salary: 3000
Salary: 5000
Salary: 1500
Salary: 1100
Salary: 950
Salary: 3000
Salary: 1300

Multiple queries happeing in adf query component using LOV

Hi,
I am using a programmatic view object in adf query component and have created List of values for one attribute by adding another programmatic ViewObject as ViewAccessor.
To populate the lov ViewObject, i have overwritten the method executeQueryForCollection in which i call the webservice to fetch the data. So lov is working fine inside QueryComponent.
I have overwritten queryListener attribute of query component in my backing bean. In the queryListener method, to populate the result grid, am populating the view object by using createRow and insertRow apis. While doing so, Whenever i do setAttibute for the lov field, the overwrittern method executeQueryForCollection getting invoked. Hence my webService getting invoked. So if i have 10 rows, the webservice is getting invoked 10 times.
I put sops in the executeQueryForCollection method for the queryMode and getName.
System.out.println("executeQueryForCollection::::"+this.getQueryMode()); i get as 7
System.out.println("executeQueryForCollection:::=" +this.getName()); i get as CurrencySummaryLOVVO_5708_findByVC_ The number 5708 varies for every row.
Please tell me How to avoid invoking the executeQueryForCollection everytime when i do setAttribute.
One workaround i have currently is to have one dummry attribute for the lov which can be used for display in grid and actual attribute will be used in Query Component for the lov to function.
Is there any other better workaround?
Thanks a lot in Advance.
Vivek

When you set a value to LOV field it tries to validate it from the LOV data. thats why it execute query.
Try setting Row Level Bind Values = false for the accessor.
yet, i would suggest to find an other way to populate values of LOV since the executeQueryForCollection will be executed many times when you use that LOV:

Dynamic query in timecard using LOV or CHOICE_LIST???
