Using jquery FullCalendar in APEX with dynamic query

Hi,
I am trying to implement jquery FullCalendar in APEX and came across thie following post but I am unable to get the events to work. I would really like to see it working with an Application_Process:
How we can highlight events in Calendar
Currently I created an Application Process that simply calls a DB table and convert it into json format.
DECLARE
v_sql varchar2(400);
BEGIN
v_sql := 'SELECT * FROM CAL_FEED';
apex_util.json_from_sql(v_sql);
END;
But I am unsure how to add the events via an Application_Process.
I have tried the following in numerious ways (events:function, url feed, etc). It does work if I just do an array but would like it as a dynamic query.
$('#calendar').fullCalendar({
events: "http://server:8080/apex/f?p=101:53:4352610578859707:APPLICATION_PROCESS=IAT_TEST_CAL_FEED"
Thank you in advance,
Jimmy

Hi,
I was able to get the events into Fullcalendar with an Application Process but not sure if this would scale well with alot of events.
Would someone be able to tell me if there is a better way?
I am currently using an On Demand Application Process called IAT_TEST_FEED:_
DECLARE
lv_cal_list VARCHAR2(16000);
lv_return_str VARCHAR2(32000);
BEGIN
FOR i IN (SELECT "CAL_FEED"."ID" as ID,
"CAL_FEED"."title" as caltitle,
"CAL_FEED"."start" as calstart,
"CAL_FEED"."end" as calend
FROM "CAL_FEED")
LOOP
lv_cal_list := lv_cal_list || '{"id":' || CHR(39) || i.ID || CHR(39) || ',' ||
' "title":' || CHR(39) || i.caltitle || CHR(39) || ',' ||
' "start":' || CHR(39) || i.calstart || CHR(39) || ',' ||
' "end":' || CHR(39) || i.calend || CHR(39) || '},';
END LOOP;
lv_return_str := '[' || RTRIM(lv_cal_list,',') || ']';
htp.prn(lv_return_str);
EXCEPTION WHEN OTHERS THEN
htp.prn('error');
END;
In a HTML Region on a page within the Region Header:_
<link rel="stylesheet" type="text/css" href="#WORKSPACE_IMAGES#fullcalendar.css" />
<script type="text/javascript" src="#WORKSPACE_IMAGES#ui.core.js"></script>
<script type="text/javascript" src="#WORKSPACE_IMAGES#ui.draggable.js"></script>
<script type="text/javascript" src="#WORKSPACE_IMAGES#ui.resizable.js"></script>
<script type="text/javascript" src="#WORKSPACE_IMAGES#jquery.js"></script>
<script type="text/javascript" src="#WORKSPACE_IMAGES#fullcalendar.js"></script>
<script type="text/javascript" src="#WORKSPACE_IMAGES#fullcalendar.min.js"></script>
<script type='text/javascript'>
$(document).ready(function() {
$('#calendar').fullCalendar({
events: function(start, end, callback) {
$.ajax({
type: "POST",
url: "wwv_flow.show",
dataType: "json",
data: {
p_flow_id:$('#pFlowId').val(),
p_flow_step_id:$('#pFlowStepId').val(),
p_instance:$('#pInstance').val(),
p_request:"APPLICATION_PROCESS=IAT_TEST_FEED"
success:function(calevents){
$.each(calevents, function(i, calevent){
$('#calendar').fullCalendar('renderEvent', calevent, true);
</script>
The line within the ajax call is basically where my concern would be
$('#calendar').fullCalendar('renderEvent', calevent, true);
Thank you,
Jimmy

Help on performance with dynamic query

Hi All,
We are using SQL Server 2008R2. In our one of report we are using Dynamic query and it is taking more time to retrieve the data. to retrieve 32 records it is taking 13-15 secs. In my observation in a table variable, created more than 60 columns. In
the SP called one more sp with insert statement.
Please let me know how i can improve performance of the SP.
I know that i have to provide the SP for observation but unfortunately I cannot provide the SP. Please guide me how i can achieve this .
I tried with temp tables by creating indexes on temp tables but i couldn't find improvement in performance.
Waiting for valuable replies.

First of all a "dynamic query" is not "a query" - it is a multitude of them. Some of them may be fast, others may be slow.
There is of course no way we can give specific suggestions without seeing the code, the table and index definitions etc.
We can only give the generic suggestions. As for the code, make sure that you are using parameterised SQL and you are not building a complete SQL string with parameters and all. If nothing else, this helps to make the code more readable and maintainable.
It also protects you against SQL injection. And it also helps to prevent performance issue due to implicit conversion.
You will need to look at the query plan to see where the bottlenecks may be. You should look at the actual query plan. Note that the thickness of the arrows are more relevant than the percentages you see; the percentages are only estimates, and estimates
are often off. Next step is to see if you can add indexes to alleviate the situation. You should also analyse if there are problems in the query, for instance indexed columns that are entangled in expression. If you are using views, make sure that you don't
have views built on top of views etc. This can often result a table appearing multiple times in a query, when one would be enough.

Apex with dynamic check box....

hi to all:
i have report emp.it contain data like eno,ename,sal,record .
example:eno ename sal record
100 a 100
200 b 3000 going on...
using this column i am making report by using apex and report contain one submit button also.
1)in this report i am creating dynamic check box depend on eno..see my coding
declare
str varchar2(3000);
begin
str:='select htmldb_item.CHECKBOX(10,eno,DECODE(record,1,''CHECKED'')) "SELECT" ,eno,ename,sal ,record from emp where 1=1';
return str;
end;
2)in process created after submit
iam created pl/code like ..this code for
declare
i number;
str varchar2(2000);
emp_id number;
begin
FOR i in 1..HTMLDB_APPLICATION.G_F10.count
LOOP
IF HTMLDB_APPLICATION.G_F10(i) is not null then
SELECT htmldb_application.G_F10(i) INTO emp_id from dual;
--insert into my_log values(emp_id);commit;
update emp set record=1 where eno=emp_id ;
commit;
else if HTMLDB_APPLICATION.G_F10(i) is null then
update emp set record=0 where eno=emp_id ;
commit;
else
null;
end if;
end loop;
end;
my requirenent:
a)if check box checked then -update -record column -1
b)if check box uncked then -update - record column -0
in process coding--
eno alway is not null only..
so i want to do check box with update the record column..like this
a)if check box checked then -update -record column -1
b)if check box uncked then -update - record column -0
pls give solution.
output i want like this example:
chebox eno ename sal record
checked(X) 100 a 300 1
checked(x) 200 b 300 1

unchecked 100 a 300 0
checked(x) 200 b 300 1

Using bind variables (in & out) with dynamic sql

I got a table that holds pl/sql code snippets to do validations on a set of data. what the code basically does is receiving a ID and returning a number of errors found.
To execute the code I use dynamic sql with two bind variables.
When the codes consists of a simpel query, it works like a charm, for example with this code:
BEGIN
   SELECT COUNT (1)
   INTO :1
   FROM articles atl
   WHERE ATL.CSE_ID = :2 AND cgp_id IS NULL;
END;however when I get to some more complex validations that need to do calculations or execute multiple queries, I'm running into trouble.
I've boiled the problem down into this:
DECLARE
   counter   NUMBER;
   my_id     NUMBER := 61;
BEGIN
   EXECUTE IMMEDIATE ('
      declare
         some_var number;
      begin
      select 1 into some_var from dual
      where :2 = 61;
      :1 := :2;
      end;
      USING OUT counter, IN my_id;
   DBMS_OUTPUT.put_line (counter || '-' || my_id);
END;this code doesn't really make any sense, but it's just to show you what the problem is. When I execute this code, I get the error
ORA-6537 OUT bind variable bound to an IN position
The error doesn't seem to make sense, :2 is the only IN bind variable, and it's only used in a where clause.
As soon as I remove that where clause , the code will work again (giving me 61-61, in case you liked to know).
Any idea whats going wrong? Am I just using the bind variables in a way you're not supposed to use them?
I'm using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit

Correction. With execute immediate binding is by position, but binds do not need to be repeated. So my statement above is incorrect..
You need to bind it once only - but bind by position. And the bind must match how the bind variable is used.
If the bind variable never assigns a value in the code, bind as IN.
If the bind variable assigns a value in the code, bind as OUT.
If the bind variable assigns a value and is used a variable in any other statement in the code, bind as IN OUT.
E.g.
SQL> create or replace procedure FooProc is
2          cnt     number;
3          id      number := 61;
4 begin
5          execute immediate
6 'declare
7          n       number;
8 begin
9          select
10                  1 into n
11          from dual
12          where :var1 = 61;       --// var1 is used as IN
13
14          :var2 := n * :var1;     --// var2 is used as OUT and var1 as IN
15          :var2 := -1 * :var2;    --// var2 is used as OUT and IN
16 end;
17 '
18          using
19                  in out id, in out cnt; --// must reflect usage above

Thanks for your reply.
I did some more investigation to check what could cause this to happene, whereby the report toatal is not displayed at all for few selected paramters.
What i could analyse was that the records returned were more than 50 (Standard Setting) , which however could not fit into the page, along with that the pagination scheme was not selected. I had to make 2 changes to the Layout of the report
Pagination Scheme : Row Ranges X to Y(with Next and Previous Links)
Number of Rows : 500
This worked for me as the displayed could not be seen on the next page with Previous and next links on the report output.
Thanks,
Dips

Problem with dynamic query in Forms Builder

Hi,
I need in forms builder cursor in procedure which parameter is a whole query. But i stuck when i wanna give some text in signs '' to procedure.

How could i pass signs '' to procedure.
Any ideas.

Pipelined Function with dynamic query

Hello All,

I am leveraging the Oracle's pipelined table function.
It's working fine for static SQL.
create or replace package test13_pkg as
    type r_disc_req is record(disc_line_id number,
                             req_id number);

Could you please guide me here?

Hi,
It's very doubtful whether you need or want dynamic SQL for this task.
If you do, however, here's one way to do it:
FUNCTION F_GetDiscReq
( p_filter1 IN edms_disc_lines_stg.filter1%TYPE
, p_filter2 IN edms_disc_lines_stg.filter1%TYPE
, p_filter3 IN edms_disc_lines_stg.filter1%TYPE
   RETURN t_disc_req
   PIPELINED
IS
   lo_disc_req   r_disc_req;
   l_sql varchar2(4000) := 'SELECT disc_line_id, req_id
                   FROM edms_disc_lines_stg ';
   l_where_clause varchar2(4000) := 'WHERE 1 = 1 ';
   c     SYS_REFCURSOR;
BEGIN
   IF p_filter1 IS NOT NULL THEN
    l_where_clause := l_where_clause||'AND filter1 = ''' || p_filter1 || '''';
   END IF;
   IF p_filter2 IS NOT NULL THEN
    l_where_clause := l_where_clause||'AND filter2 = ''' || p_filter2 || '''';
   END IF;
   IF p_filter3 IS NOT NULL THEN
    l_where_clause := l_where_clause||'AND filter3 = ''' || p_filter3 || '''';
   END IF;
   l_sql := l_sql||l_where_clause;
--   dbms_output.put_line (l_sql || ' = l_sql');   -- For debugging
   OPEN c FOR l_sql;
   LOOP
      FETCH c INTO lo_disc_req;
      EXIT WHEN c%NOTFOUND;
      PIPE ROW (lo_disc_req);
   END LOOP;
END F_GetDiscReq;
Static SQL will, in general, be more efficient than dynamic SQL.
Given that you need dynamic SQL, there are lots of ways the function above could be made more efficient. If that's an issue, make sure you understand what this is doing before trying to improve it.

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

" has salary " + empIter.sal() );
empIter.close();
</PRE>
Please guide me what should I do to get it working.
null

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
}

Create Portal Page Design with Dynamic content in Moss2007(without using Visual Studio)

Hi All,
I am facing a issue while designing a page in MOSS 2007. I can't use custom code as the client doesn't want it to be used.
The page is with dynamic content coming from sharepoint lists and picture library. I tried using SharePoint Listview after adding zones as per my page design..but was unsuccessful because I am unable to change its design and css styles in its xslt view.
Plesae help me to find any alternative so that I can easily style my page with the dynamic content. Is there any way using Content editor webparts? Can we get List data in Content editor html as this can be easily styled. I googled and tried it by using javascript
and jquery but again unsuccessful.
Please help me with some solution.
Thanks..!!

Error using JQuery

Hi folks,
I am trying to use JQuery in my apex application. I downloaded and installed JQuery library via Shared Components > Static files and associated it with my application.
In my page template, between <head> and </head>, i included the following
*<script src="#APP_IMAGES#jquery-1.3.2.min.js" type="text/javascript"></script>*
and saved the changes.
I created a <div> element on my page and tested using the ff code from Tyler Muths blog
It should turns any div on the page red when you hover over it, then white when you move your mouse out of it.
*$(document).ready(function() {*
*$("div").hover(function() {*
*$(this).css('background-color','#ff0000');*
*function() {*
*$(this).css('background-color','#ffffff');*
I placed the above code in my page HTML Header section but when i ran the page and moved my mouse over the div, nothing happens. FireBug displays an error *"$ is not defined"*
Any clues as to what i may be doing wrong?
Thanks.
Stephen.

I remember having a similar problem with some other jquery function. What I did was to copy the deffinition of the function in the page zero. After that the script would work.

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:
http://www.sqlusa.com/bestpractices/dynamicsql/
As noted above, more information needed to decide if dynamic SQL the correct solution in this instance.

Using JQuery with Apex

Hello, I have a question for those of you who are using JQuery with Apex:
This is my HTML header:
<script type="text/javascript" src="&WORKSPACE_IMAGES.jsapi.js"></script>
<script type="text/javascript">
google.load("jquery", "1.3.2");
</script>
The problem is that JQuery still loads from Google and since the Company Intranet has the cookies blocked the privacy icon appars in IE. I am sure somebody will one day notice this and it's gonna be a "big" problem.
I suspect that something must be changed below to make the privacy icon dissapear,
if (!window['google']) {
window['google'] = {};
if (!window['google']['loader']) {
window['google']['loader'] = {};
google.loader.ServiceBase = 'http://www.google.com/uds';
google.loader.GoogleApisBase = 'http://ajax.googleapis.com/ajax';
google.loader.ApiKey = 'notsupplied';
google.loader.KeyVerified = true;
google.loader.LoadFailure = false;
google.loader.Secure = false;
google.loader.GoogleLocale = 'www.google.com';
Any ideas how to change this code and if this is going to work?
George

Hi,
If you do not like use jQuery from Google, discard your code
<script type="text/javascript" src="&WORKSPACE_IMAGES.jsapi.js"></script>
<script type="text/javascript">
google.load("jquery", "1.3.2");
</script>and use e.g. this guide to integrate jQuery to your Apex apps

How to use a LOV object in apex with the parameter?

Hi,
I would like to create a LOV object with a query:
SELECT ID, NAME
FROM TABLE
WHERE
REF= APEX_FORM_VARIABLE
This is for an Apex report page and each row provides the Apex form variable.

What is your question then?
Just create a dynamic LOV with that as your query. Use the bind variable notation for the apex item.

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 build dynamic query strings in the query using DB adapter 'Pure SQL'

Dear Forum,
I am building an application which will access DB to fetch some result set. The query involves retrieving data from multiple tables(nearly 10 tables). So I have created a DB adapter using 'execute pure sql' option. With this query works fine, but my inputs parameters will vary. So I need to make my query dynamic to append the query strings at runtime depending on the inputs.
For example I have 3 input variables - input1,input2 and input3 (in my request xsd) which are used in the pure sql query. Now if I get a 4th input parameter input4 in the request, I need to append this to query string as 'AND input4=[some value]' at runtime. Otherwise my query should have only 3 parameters. Please suggest how this can be achieved.
Regards,
Satya.

This is a strange requirement, depending on the columns you have and what are optional in them, one way is to have separate operations and each opeartion will have different inputs and for each operation , a different DB Adapter is called. But this way, it results in more number of operations for the service as well as more number of references in the composite. Even if you pass the column inputs to the SQL procedure, it will result in a large number of if-else cases..
Thanks,
