How do I pass MySQL function calls in PreparedStatements?

I want to pass the NOW() function in a PreparedStatement. I am currently using setString(1, "NOW()") but the statement isn't working. I don't know if this is cause but I figured it to be the most likely suspect.
Thanks.

I don't know if this is cause but I figured it to be the most likely suspect.Nope, bad design.

How? Flex pass variables or call function in SWF

Dear All:
I am new in Flex.
But I stuck with a problem for weeks.
I wish to communication between Flex and Flash(swf).
I tried to pass variable from Flex to Swf. (Call function in Swf also pass variables)
I did some tourital on google by using SWFLoader, which works fine.
BUT the AS code in SWF must in MAIN FRAME.
I need put my AS code by using DOCUMENT CLASS.
BUT when I using Document class, the method is not working.
The flex cannot find function in Flash.
PS.I already set main.as class as public
Hope some one can give some hint.
I really get a huge headache.
Many thanks,
Henry

thanks but this does not work.
I think that the problem is that the variables defined in the
for loop do not exist in the scope of
the function.
when the MC is clicked, and the onRelease function says:
_root[mcName]._x=0;
the variable "mcName" is empty.

How to make a dynamic function call from within a package procedure

Hi:
I need to call a function dynamically (name and parameters determined at run time, but return value is known:always an integer). I can build the call and place it in a dynamic sql using dbms_sql. But the function is inside a package and is not public.
So, if I issue:
dbms_sql.parse( cur,'SELECT '||call||' FROM dual', dbms_sql.v7 )
where call is "DOS(234,'V')"
I get:
ORA-00904: "DOS": invalid identifier
If I make the function ("DOS") public and "call" equals "pack.DOS(234,'V')", it works fine, but I don't want to make it public.
Is there a solution?
Thanks in advance
RuBeck

Hi, Kamal:
Calling from outside of the owner package is not possible if it is not public.The calls are from inside the package. It looks like the dynamic select is executed "outside" the package, so the private function is unknown
Make it available in the package headerLooks like it's the only solution
How often this will be executed?This is a library for loading files into tables and executing dynamic validation procedures.
Here's an example of the mechanics:
create or replace package mypack as
function one return number ; -- public function
procedure execute_it( p_name VARCHAR2 ) ;
end ;
create or replace package body mypack as
function one return number is
begin
return 1 ;
end ;
function two( i number, s varchar2 ) return number is -- private function
begin
return 2 ;
end ;
procedure execute_it( p_name VARCHAR2 ) is
select_str VARCHAR2( 1000 ) ;
v_num NUMBER ;
cur NUMBER ;
nf NUMBER ;
begin
select_str := 'SELECT '||p_name||' FROM dual' ;
cur := dbms_sql.open_cursor ;
dbms_sql.parse( cur,select_str,dbms_sql.v7 ) ;
dbms_sql.define_column( cur,1, v_num ) ;
nf := dbms_sql.execute( cur ) ;
IF dbms_sql.fetch_rows( cur ) = 0 THEN
RAISE no_data_found ;
END IF ;
dbms_sql.column_value( cur, 1, v_numero ) ;
dbms_output.put_line( p_name||' returns '||v_num ) ;
dbms_sql.close_cursor( cur ) ;
end ;
end ;
begin
mypack.execute_it( 'mypack.one' ) ; -- Call public function: Works fine
mypack.execute_it( 'two(234,''v'')' ) ; -- Call private function: error 0904
end ;
Thanks for your hints

How to speed up JCO function call

Hello,
i have some function module in r/3 which returns a huge amount of data. When i am testing this fm in r/3 this function takes few seconds for executing. But when i run this function with jco from java it takes about ten times more :(.
Is there - eg in jco - some possibilities of speeding up connection - or another technologies i can use? (i would like to try make xml in abap and pack it..is it good idea or the result will be only my waste time?)
thanks for each answer...
JJ

Hi,
I can't see how you can significantly increase the jco speed, but you can using caching if possible(particularly at the java side) and your other suggestion make sense. I expect you don't present all that data you are fetching, so perhaps you should move the heaviest business logic to the ABAP side and only transfer the results ?

Passing a method call to a facelet tag

Hello,
I am trying to create a JSF confirmation box that replaces the Javascript confirm() function. I am using Seam and Rich Faces 3.2.1. The confirm box is a facelet tag that pops up a modal box with 'cancel' and a 'continue' buttons. Everything is working correctly except for one crucial piece; passing the method call for continue button.
Here is the set up for the facelets tag in the main xhtml page:
<at:confirm
    id="confirm"
    title="Confirm"
    message="Do you want to continue"
    buttonText="Continue"
    backingBean="#{confirmAction}"
    method="testMethodTwo"
/>Here is the code for the button inside the facelets tag:
<a4j:commandLink
    styleClass="rdSplGr1"
    href="#"
    action="#{backingBean[method]}">
    <s:span>#{buttonText}</s:span>
</a4j:commandLink>The method simply does nothing when the use clicks the button. I am assuming this is due to the lack of "()" however there does not seem to be a way to get those in there. I have tried the following:
1) placing the parens like this - method="testMethodTwo()"
2) placing the parens like this - action="#{backingBean[method]()}"
The first does nothing, the second causes an EL exception.
I know that it has nothing to do with the modal as I have also placed a button like this into the modal:
<a4j:commandLink
    styleClass="rdSplGr1"
    href="#"
    action="#{confirmAction.testMethodOne()}">
     <s:span>MethodOne</s:span>
</a4j:commandLink>That button as you can see has what I am trying to create dynamically and it works like a charm.
So how do I pass a method call correctly? Or if that is impossible how do I solve the problem of having a the continue button having a different method assigned to it?
Thanks for any insight into this.

I agree, reflection should be a last resort. An
interface would not be useful if you don't know what
method you want to invoke at compile time. Interfaces
are useful when you know the method you want to
invoke, but not the class.That's not true. This is a really lame-ass example but it shows the point.
public interface RuntimeMethod
   public void method();
class AClass {
   public static void main(Sting[] args)
      new AClass.handleAtRuntime(
         Factory.getRuntimeMethod(Integer.parse(args[0])));
   public void handleAtRuntime(RuntimeMethod runtime)
      runtime.method();
class Factory
   public static getRuntimeMethod(int method)
      switch(method)
         case 0: return new RuntimeMethod
            public void method()
               methodA();
         case 2: return new RuntimeMethod
            public void method()
               methodB();
         default:
            throw new IllegalArgumentException("bad input");

How to pass a JSP var to a Script function called in a netui:checkbox

How to pass a JSP variable to a Java Script function called in a netui:checkbox onSelect?
I have a requirement where based on the checkBox selected or deselected in a repeater tag I would have to select or deselect other checkboxes in a netui:form. I am trying to pass the index or unique name of the checkbox to the JavaScript function. When I try this code I am getting a Syntax Error!! and getting a " item undefined" in the javascript. This works when I use just the html form tag but when I use the <netui:form> tag I am facing this issue. Any help would be highly appreciated.
function selectACheckBoxOnClick(name) {
alert ("called selectACheckBoxOnClick ");
alert ("called name "+name);
<netui-data:repeater dataSource="{pageFlow.unregisteredContractAssetsDTOArr}">
<netui-data:repeaterItem>
<% String checkboxName = "selectACheckBox_"+i;
String serialNum = "serialNum_"+i;
String hidenboxName = "hiddenACheckBox_"+i;
String loopNo = new Integer(i).toString();
System.out.println("Loop String :"+ loopNo);
System.out.println("CheckBox Name:"+ checkboxName);
System.out.println("serialNum :"+serialNum); %>
<tr bgcolor="#ffffff">
<td align="center">
<netui:checkBox dataSource="{container.item.selectedAssetFlag}" onSelect="selectACheckBoxOnClick(<%=checkboxName%>);" tagId="<%=checkboxName%>"/>
</td>
          <td class="small"><netui:label value="{container.item.model}"/></td>
          <td class="small">
<netui:hidden dataSource="{container.item.splitAssetNo}" tagId="<%=serialNum%>"/>
<netui:label value="{container.item.serial}"></netui:label></td>
          <td class="small"><netui:label value="{container.item.equpimentId}"/></td>
          <td class="small">
<netui-data:getData resultId="siteId" value="{container.item.siteNo}" />
<%String siteId = (String) pageContext.getAttribute("siteId");%>
<netui:anchor action="getSiteLevelAssets" formSubmit="true">
<netui:parameter value="{container.item.siteNo}" name="siteNo" />
<netui:label value="{container.item.siteNo}" />
</netui:anchor>
</td>     </tr>
<%i++;%>
</netui-data:repeaterItem>
</netui-data:repeater>
This code works within a form:
               <td align=center>
                    <input type=image name="unassign" onclick="javascript:unassignReplacement(<%=replacementSupply.getPMSupplyId()%>)" src="<%=request.getContextPath()%>/images/bt_sm_x.gif" border=0 alt="Unassign">
                    </td>
Thanks,

hi
i did not go thru your code completly
but u can use the following for your problem
the checkbox in the repeater must have unique TagID
counter = 0; (initialize)
<netui-data:repeaterItem>
<netui:checkBox dataSource="" tagId='<%="count"+String.valueOf(counter)%>' onClick="some function()" />
<%counter++;%>
</netui-data:repeaterItem>
here if u have 3 checkbox
They will have Tagid's as count1 , count2 and count3
now in the javascript somefunction()
use the following line
for(j=0;j<<%=counter%>;j++)
document.forms(0)[getNetuiTagName"count"+j)].checked=false;
}

How can I ensure a function is called only once in a query?

I have a function (in a package) that returns the start date and end date to be used by my query. The query was taking bind variables but when I updated it to use the function calls it slowed down a lot.
I tried creating an inline view that selects the start and end date and joins with the other table but this does not help. I thought the inline view would only be run once but this is not the case. I have my function print out a value from a sequence and i see that it is called thousands of times.
Why would the procedure call be so much slower?
How can I ensure that the function is only called once in the query?
This is what I currently have:
SELECT col1, col2
FROM aTable,
(SELECT proc.getStartdate startDate,
proc.getEndDate endDate
FROM dual) dt
WHERE aTable.theDate >= dt.startDate
AND aTable.theDate <= dt.endDate
Thanks

They get the begining and ending dates to be used by the query.
My application uses the Oracle Portal. Each user can select their date range and it is stored as a user preference. The portal API provides funcitons for retrieving the preferences and I have encapsulated it in my procedure so the developers do not need knowledge of the portal. If they just restrict their queries to the dates returned by this function they will get the needed data.
Our work around as been to pass these date variables around as bind variables.

How to debug PL/SQL functions? Passing parameter and debugger error

Hi,
How to debug a PL/SQL function in JDeveloper? There are two problems with it:
1) Don't see how it's possible to pass parameters required by function call (in the dialog opening after Debug -> Debug FUNCTION_NAME)
2) In a function returning table_name%ROWTYPE (and having a record declaration for table_name%ROWTYPE), debug gives error:
PLS-00103: Encountered symbol "/" when expecting one of ... in line
v_Return PL/SQL RECORD;
Debugging procedures works as expected.

Function calling function passing data

We have developed an MQSERIES utility that is a function that calls many related functions and its purpose is to perform a variety of MQSeries functions with minimal interaction required by the user. The user provides the message, an activity code (pd for puts, gd for gets, pr for putting requests for replies, etc.) and a couple other parameters. The user gets back the message, a return flag (good, bad, truncated, etc). . Our MQSERIES function is a function of the calling module. Our function has it's series of includes with classes, functions, etc. The calling program needs a couple includes (to define the passed data areas) and a function prototype of our function (void mqcmd090(typefilefdi &, typefilemsg &, typefilemdi &);) and after the user does string copies and so forth into the passed data areas they currently call the function (mqcmd090(currpassarea, currmessage, currquetable);) After our function is called these passed data areas are manipulated by the user's module. They inquire into the return code, they may do activity (with message ids, etc), they manipulate the message and may send it back (replies, etc). Our dilemma is this. The users want our module to be stand-alone. It should be compiled and linked by itself. Their module should be compiled and linked by itself. They don't mind having a couple includes for the common passed structures but our modules should not be a function in theirs.
How can I compile our function (and how can they call it) so that we can keep the communications going both ways between modules? A system call can't do it because they can send us information but they can't receive information back. If our module needs an upgrade we should just be able to change and recompile ours and their next execution should get the changes.
I am at a loss and would greatly appreciate any assistance on this matter.
Thanks,
Dennis Bartizal

How to call a C function calling a Java Method from another C function ?

Hi everyone,
I'm just starting to learn JNI and my problem is that I don't know if it is possible to call a C function calling a Java Method (or doing anything else with JNI) from another C function.
In fact, after receiving datas in a socket made by a C function, I would like to create a class instance (and I don't know how to do it too ; ) ) and init this instance with the strings I received in the socket.
Is all that possible ?
Thank you very much for your help !

Hard to understand the question, but by most interpretations the answer is going to be yes.
You do of course understand that JNI is the "API" that sits between Java and C and that every call between the two must go through that. You can't call it directly.

How to pass a function with the same argument multiple times and return values in variables?

The problem I have is I created a function which really is some kind of database. Basically a bunch of:
if (a.value == "this number"){
b.value = "this expression";
Inside the form are 2 dropdown lists that return numerical values which I want to process through that function and put the return value inside separate variables.
var a = this.getField("OPE003.EVEN.1.MIP");
Mip(a);
var result1 = Mip();
I tried to overwriting *a* to process the second field
a = this.getField("OPE003.EVEN.2.MIP");
Mip(a);
var result2 = Mip();
result1 and result2 are put in an array, joined as a string.
Doing so, I always get the last processing twice as the final result.
Can I use a function as a batch processing tool that way?

You are right, I changed the code to what you said but how do I pass another value through my fonction so I can get Result1 and Result2?
is it
var a = this.getField("OPE003.EVEN.1.MIP");
var b = this.getField("OPE003.EVEN.2.MIP");
var result1 = Mip(a);
var result2 = Mip(b);
var c = new Array[result1, result2]

Is it possible to pass table name as parameter to function calls?

Let's say I would like to retrieve data from table BSAD, BSID, BSIS, BSAS with the exact same WHERE conditions.
I.E.
      SELECT SINGLE * FROM bsis
           WHERE bukrs = zbukrs
             AND belnr = zbelnr
             AND gjahr = zgjahr
             AND buzei = bseg-buzei.
      SELECT SINGLE * FROM bsas
           WHERE bukrs = zbukrs
             AND belnr = zbelnr
             AND gjahr = zgjahr
             AND buzei = bseg-buzei.
Is there a way that I could put them into a function and do something like?
perform select_table_bsas using 'bsas'.
perform select_table_bsis using 'bsis'.
and I should get SELECT * FROM passed from the function calls.
Thanks.

Hello,
You can try something like this
DATA : LV_DBTAB1 LIKE DD02L-TABNAME.
DATA : DREF TYPE REF TO DATA.
FIELD-SYMBOLS: <ITAB> TYPE ANY TABLE. " used to store dynamic tables
LV_DBTAB1 = 'MARA'. " in caps
CREATE DATA DREF TYPE STANDARD TABLE OF (LV_DBTAB1)
                            WITH NON-UNIQUE DEFAULT KEY.
ASSIGN DREF->* TO <ITAB> .
* chooses only english values
SELECT * FROM (LV_DBTAB1) INTO TABLE <ITAB> WHERE SPRAS = 'E'.
here, even the internal table is dynamic, but that can be static if you know the structure for sure
