States question

Hello, just learning Flex and states.
I have created a new state. I thought a new state was
basically a blank canvas to start constructing a new view in Flex.
However when I start to add components to the stage in my new
state, they are positioning themselves relative to components on
the base state ?
How do I start with a clean slate, so to speak ?
Thanks for any help.

SQL statement question

I'm trying compare two table in Oracle and with a firstname and
lastname
matches fill-in a pager pin number.
This is the sql statement I'm running
update addressbook2 set pin =
(select pin from phonebook where
phonebook.firstname=addressbook2.firstname
and
phonebook.lastname=addressbook2.lastname)
where addressbook2.firstname IN (select firstname from phonebook)
and addressbook2.lastname IN (select lastname from phonebook)
but I get an error message saying:
ORA-01427: single-row subquery returns more than one row
My question is can I update the table even when there are
duplicates in the tables. The query runs perfect when both
tables are unique.
Thank you for any help.

I presume you are trying to update the pin of only those people
in the addressbook table that also exist in the phonebook table.
The following will work:
update addressbook a
set a.pin = (
select f.pin from phonebook f
where f.fname = a.fname
and f.lname = a.lname
ie remove the last two lines from your DML statement.. be aware
that you are using a denormalised design (pin is not normalised
on the primary key) and the use of first and last names as a
method of identifying people is not a good idea (does 'smith' =
'smyth'?)

View State question - changing states and custom states

Hi all,
I'm working on an application that lets a user register for an event. Each event has associated child information: conferences, tickets, etc. associated with it. What I'm trying to do is create some sort of checkbox list so that, when a user clicks on an event to add it to his registration, the associated child information appears in the display so he can choose all this information at once. I have the list working and I've been trying to use a custom ItemRenderer to pop in the extra info for the user to select when he clicks on an event. The problem I'm having is that, when the user goes to click on a child to add it to his registration, my state is changing back from "selected" to "normal" and the child information disappears. So I guess I have two questions. One, am I even remotely on the right track here? If not, can someone suggest a better approach? Two, if this is the right approach, how do I solve the "disappearing child" problem? I tried creating a custom state that would set everything to visible, but I can't seem to figure out how to get into it...I tried just putting a click event on it and just doing an Alert.show(currentState) to see if I was even getting into my custom state, but I just kept switching between "normal" and "selected."
Code:
ItemRenderer:

Access 2003: sql statement question

Dear all,
i'm trying to get the following code to work without success:
String com = "SELECT Instrument.Index FROM Instrument WHERE Instrument.NextCalDate < #5/24/2007#";
s.execute(com);
I get the following error: Error: java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in query expression 'Instrument.NextCalDate < #5/24/2007#'.
It is because of the <. If i change the < by an = it works fine. The annoying thing is that i've been browsing the forum and some date related questions regarding java/access were explained by giving example code that had the exact same syntax as the code i'm using, so with the use of the < character without using escape characters or whatever. These postings however date from 2004 or something, so what has changed?
I'm using latest JDK, Access 2003 and am connecting via ODBC running on an XP Pro machine.
Help is very much appreciated. Thanks from The Netherlands

I suspect one thing that changed was that those other examples were using a previous version of MS Access.
Other than that I can only suggest that you use a prepared statement rather than attempting to the MS Access specific syntax.

Order of execution of static { } statements question

Hi,
I have a question about the order of execution of static statements. Let's imagine the following Class B inheriting of Class A:
public class A {
    static { // My static code for A };
public class B extends A {
    static { // My static code for B; };
}I know that static statements are executed when classes are loaded, but does Java guarantee an order of execution of static statements between inherited classed (like for constructors) or is it 'random' in that it depends which class is loaded first?
Thanks,
J.

Jrm,
My advise with this and all such questions is "Suck it and see"...
Have compiler, will travail ;-)

Barclay statement question

This may be a stupid question, but I am just getting back to CC's after a very long time. My account due date is the 8th, statement is the 11th. I paid more than what they said was the statement balance when I went to pay the amount due. But when I look at my account it still shows the previous statement balance as it was before the payment (even after the payment cleared and posted).Is that normal? I am afraid I am missing something as I still use the card. Then it has the "current balance", that is what I need to pay down before the 11th correct?So really I need to pay down the whole current balance around the due date (8th / 11th)? Maybe I am just worn out, but for some reason I am having issues trying to get this right. Thanks.

Statement balances do not reduce after you pay them off. The statement balance is the balance on the card the last time your statement cut. Assuming a due date of the 8th and a statement date of the 11th, as you stated, this is how it works. May 1 - Outstanding balance = $500. May 3 - Paid $500; Outstanding balance = $0. May 5 - Spend $500. Outstanding balance = $500.May 8 - Due Date. $0 due, but $500 outstanding balance. May 11 - New statement cuts. New statement balance = $500. May 20 - Spend $500. Outstanding balance = $1000. Statement balance = $500. May 25 - Pay $1000. Outstanding balance = $0. Statement balance = $500. June 11 - New statement cuts. Statement balance = $0. Hopefully the above helps clarify how it works. Statement balance will always show the balance on the last statement cut date. Outstanding balance (or current due or some variant) is the total amount due. If you pay the statement balance in full, you won't get charged interest even if the current due is not paid in full. The CC system is based on the mail in payment system. Since it was created before the internet, instant online payments were not feasible. Thus, you pay your last months statement balance before this months due date, giving you time to mail in the payment.

Update statement, question

I’ve got a question which is probably very simple to you, but very difficult to me..
I’ve got the following (existing) update statement in an Oracle package:
-- update the aggregated batch fields (blocking flag is 1 if query fact exist with BF=1 or if no query facts have been generated and
-- for this group a query dimension record exist with blocking flag data or sql set to 1
update qf_f_batch bat
set (ts_ended_tz, ts_ended, nbr_error_msgs, blocking_flag) =
(select coalesce(max(sysdate), sysdate),
to_char(coalesce(max(sysdate), sysdate), 'DD/MM/YYYY HH24:MI:SS') ,
coalesce(sum(qryres.dummy_flag), 0),
case when
coalesce(count(qry.fk_query), 0)=0 and max(dqry.blocking_flag_data) > 0 or
coalesce(count(qry.fk_query), 0)=0 and max(dqry.blocking_flag_sql) > 0 or
coalesce(count(qry.fk_query), 0)>0 and sum (qry.blocking_flag) > 0
then 1 else 0 end as blocking_flag
from qf_d_query dqry
left outer join
( select fk_query, blocking_flag from qf_f_query
where fk_batch = varBatchKey) qry on (dqry.pm_primarykey = qry.fk_query)
left outer join
( select fk_query, dummy_flag from qf_f_query_result
where dummy_flag = 1
and fk_batch = varBatchKey) qryres on (qry.fk_query = qryres.fk_query)
where dqry.pm_current_flag = 1
and dqry.enabled = 1
and dqry.query_group = sGroup)
where bat.pm_primarykey = varBatchKey;
The update statement for nbr_error_msgs is incorrect (marked in bold, repeated here: coalesce(sum(qryres.dummy_flag), 0) )
The correct update statement for field NBR_ERROR_MSGS is :
UPDATE QF_F_BATCH b set B.NBR_ERROR_MSGS = (SELECT COUNT(F.ERROR_MESSAGE)
FROM QF_F_QUERY_RESULT FF
JOIN QF_F_QUERY F ON FF.FK_QUERY = F.FK_QUERY AND FF.FK_BATCH = F.FK_BATCH
WHERE F.FK_BATCH = B.PM_PRIMARYKEY
GROUP BY F.FK_BATCH
How can I integrate the second SQL statement into the first statement? Obviously, if I add the second SQL statement into the package, then the package will do an update of the complete QF_F_BATCH table, which contains thousands of records. Obviously I want to only update the current batch (using varBatchKey).
I am not an SQL expert (far from…) so for me this is extremely complicated. Can you help me?
Thanks in advance!

Hi,
welcome to the forum.
Please read SQL and PL/SQL FAQ
Additionally when you put some code or output please enclose it between two lines starting with {noformat}{noformat}
i.e.:
{noformat}{noformat}
SELECT ...
{noformat}{noformat}
Your query is quite complex and without sample data (CREATE TABLE and INSERT statements) it is not easy to help you.
Regards.

Stats question

Hi All
This is related to schema stats from production to QA.
We have two DB
Production: ABC
QA: XYZ
Now,
I did export for schema ABC from production and inported the complete schema using 'fromuser and touser' option for exp into XYZ.
Then i created table for production (ABC) stats using :
exec dbms_stats.create_stat_table(ownname => 'ABC', stattab => 'ABCSTATS', tblspace => 'ABC_DATA');
Then, i gathered the stats:
exec dbms_stats.export_schema_stats(ownname => 'ABC',statown=>'ABC', stattab=>'ABCSTATS');
then, exported the table 'ABCSTATS' to file exp.dmp and imported into QA database XYZ.
PROD: exp file=/exp.dmp tables=ABCSTATS
QA: imp file=exp.dmp fromuser=ABC touser=XYZ
Now, i have complete data from PRODUCTION in QA and stats for production too in table ABCSTATS.
Now, When i do
exec dbms_stats.import_schema_stats(ownname => 'XYZ',statown=>'XYZ', stattab=>'ABCSTATS');
Then command runs sucessfully. But stats are not loaded as of procution.
I have stats cost coming for one query as 40,000 in production whereas in QA it is coming as 7,000 only.
Now the question is, is there something i am doing wrong? Or is this possible to load schema stats from one to another schema for same data structure.
OS: Sun10
DB: 10G 10.2.0.3.0
Thanks

this possible to import diffrent schame stats into other? Can someone confirm?its possible. you have to perform few manual tasks.
create the stat table in source and export source schema stats.
export the stat table from source using exp utility.
transfer and import the stat table into target database.
Now, the Schema in Stat table isn't available in your target.So, you have to update the STAT table column C5 to target schema name.
Now, Import the stats using exec dbms_stats.import_table_stats.
Any special reason you want to do this? Instead, you can gather stats in current Target schema?

UNDO stat Question?

I am reposting my previous question regarding undo stats in more clear format.
I need a sql which should display the last 7 undo stats in the following format.
parameter day1 day2 day3 day4 day5 day6 day7
sum(undotbs) 100 200 300 400 500 600 700
sum(txncount) 100 180 280 300 400 500 200
max(maxquerylen) 200 150 300 120 120 230 340

I think Daniel's answer in this thread says it all.

If statement question in Adobe Designer

This code here:
else if(application.page1.citizen.rawValue==0){
app.alert("Please select whether you are a United States citizen");
xfa.host.setFocus("application.page1.citizen");
else if(application.page1.citizen.rawValue==2){
app.alert("Please select whether you are legally permitted to be employed in the United States");
xfa.host.setFocus("application.page1.legally");
The first if statement checks to see if the group of radio button(s) "citizen" has been selected (yes or no). Works fine. If the citizen radio button with a value of 2 (no) has been selected, kick out another error message indicating additional radio buttons (legally) is needing selection. This is my problem, when I select yes or no on the "legally" group of radio buttons, the second alert keeps popping up. Why can't it kick out and go on through the page? Am I missing something logically in the JS?
Any help or suggestions would be appreciated.

Well, I've been thinking that and I can't nail what I could be missing logically. I've got:
else if(application.page1.citizen.rawValue==0){
app.alert("Please select whether you are a United States citizen");
xfa.host.setFocus("application.page1.citizen");
else if(application.page1.citizen.rawValue==2){
else if(application.page1.legally.rawValue==1 || application.page1.legally.rawValue==2){
app.alert("Please select whether you are legally permitted to be employed in the United States");
xfa.host.setFocus("application.page1.legally");
The second if statement checks to see if they selected "no" for citizen. I've added in another if statement checking to see if legally radio buttons have already been filled in. Using the above approach kills my script from executing period.

Import statement question

what's the difference between
import java.util.Vector;
and
import java.util.*;
is there any difference in bytecode generated? or time takes to compile?
what's the best practice?

Yes there is a best practice, it's the one you mentioned. Use the more specific import statement. If you're only using one or two classes from a package, explicitly name them in the import statements. That way somebody else reading your code (which includes yourself, six months later) can immediately get a better understanding of your code.
If this rule is followed, and you see this as the first line of a source file:
import java.util.StringTokenizer;
then you know the StringTokenizer is being used. But if you saw this:
import java.util.*;
you wouldn't know which one is being used until you're deep in the code.
Knowing right away whether a class is tokening a string, versus say using collections, makes it a lot easier to read.
You should only use the whole-package include if you're importing a really big part of the package. For example:
import java.awt.*;
is probably OK because it's relatively unlikely a person will use only a couple classes from that package.

JDBC Sender update SQL Statement Question.

I was wondering if there is a way to have the update SQL statement line in the JDBC sender update by time stamp, this would be very helpful. Does anyone know a method of doing this?

In the SAP documentation of the adapter it has this example for using the update SQL statement after the query statement:
SQL statement for query: SELECT * FROM table WHERE processed = 0;
SQL statement for update: UPDATE table SET processed = 1 WHERE processed = 0;
What I want is to be able to put processed = (the current date) instead of processed =1 in the update statement, like this example:
SQL statement for query: SELECT * FROM table WHERE processed = 0;
SQL statement for update: UPDATE table SET processed = (the current date) WHERE processed = ' ';
I seems like you can only use a fixed value for the update statements in the JDBC Sender though, I would like to know if you can use a time stamp or variable there.

Missing return statement question

I got a missing return statement error when i compile in this code but however i dont get any missing return statement errors in the second code that i pasted here.. What is the difference i didn't get it ? Thank you.
public class primechecker {
    static double remainder = 0;
    public static boolean primecheck(int number){
         for(int i=2; i<number; i++){
              remainder = number % i;
              if (remainder == 0){
                   return false;
         if (remainder !=0){
              return true;
    public static void main(String[] args) {
         System.out.print(primecheck(10));
}That is the second code which gives no error.
public class positiveornegative {
   public static boolean numbercheck (int number){
     boolean booleann = true;
     if(number > 0){
         return true;
     else if (number < 0){
         return false;
     else {
          return false;
    public static void main(String[] args) {
         System.out.println(numbercheck(-2));
}

In your first snippet, the compiler has no guarantee that the for loop will be executed at all. That leaves only one return inside an if condition which again it has no guarantee that it will ever be reached(the if test may fail). This leads the compiler to the conclusion that your method may never return anything at all. Yet it's definition says that it must return a value.

Newbie question :- An IN statement question

I have the following issue.
I want to use an IN statement (As below), This will enable the user to enter upto 5 serial numbers.
select col.contract, col.order_no, col.customer_no, ci.name Customer_Name, odn.ship_address1, odn.ship_address2, odn.ship_zip_code, odn.ship_city, odn.ship_county, co.customer_po_no, col.part_no, col.catalog_desc Description, ith.serial_no,
col.real_ship_date Ship_Date
from
customer_order_line col,
customer_info ci,
inventory_transaction_hist ith,
customer_order co,
customer_order_deliv_note odn
where
col.customer_no = ci.customer_id
and
col.contract = ith.contract
and
col.order_no = ith.order_no
and
col.part_no = ith.part_no
and
col.order_no = co.order_no
and
col.contract = co.contract
and
col.contract = odn.contract(+)
and
col.order_no = odn.order_no(+)
and
ith.serial_no IN ('&S1' , '&S2' , '&S3' , '&S4' , '&S5')
and
(('&FROM_DATE') is null or ('&TO_DATE') is null or
dated between to_date('&FROM_DATE','DD/MM/YYYY') and to_date('&TO_DATE','DD/MM/YYYY') + ( 1 - 1/ ( 60*60*24 )))
The problem is that if they don't enter any serial numbers it return no values.. (it should do).. How can I I amend this SQl so if S1/2/3/4/5 has null values it does return some data

Hi,
Well it will return customer order's, If I took out the IN statement and run it.. it will promt me for a date range and it will return a load of Customer Orders within that date range..
With the IN statement, If I put a serial number and and specify a date range it will only bring back customers orders with that serial number in them.. The problem is if they don't specify a serial number and enter a date range nothing comes back ? It like I need to enter and if null blah blah

Spry 2.0 -- over state question

I am using the adobe widget browser for a horizontal spry menu for the first time and can't seem to get an over state to work. Can anyone post code to get this working? And is there a way to make the over states work when putting the menu in an include or library?
Thanks

Add the following to your document
<script type="text/javascript" language="javascript">
function InitPage(){
Spry.$$('#MenuBar li').forEach(function(node){ /* for FF Chrome etc */

     if(a.href == window.location){
          Spry.Utils.addClassName(node,"activeMenuItem");
Spry.$$('#MenuBar div.MenuItemContainer').forEach(function(node){ /* for IE */
     var a=node.getElementsByTagName("a")[0]; // finds all a elements inside the li, but we only want the first so [0]
     if(a.href == window.location){
          Spry.Utils.addClassName(node,"activeMenuItem");

Generate INSERT Statements question

Is there a built-in PL/SQL procedure that SQL Developer utilizes to generate the INSERT statements when one exports data from a worksheet in 'insert' format? Is it part of the DBMS_METADATA package?

No this is all done in Java, we use the DBMB-METADATA only for generating DDL...
