How to use a variable multiple times in the data flow

DECLARE
@StartTime datetime,
@EndTime datetime
SET @StartTime = (SELECT MAX(AvailDateTime) FROM dbo.Fact)
SET @EndTime = (SELECT MAX(AvailDateTime) FROM dbo.Product);
--DATEADD(day, 1, @StartTime);
--PRINT @StartTime
--PRINT @EndTime;
WITH
dates AS (
SELECT DATEADD(Minute,5,@StartTime) AS [date]
WHERE DATEADD(Minute,5,@StartTime) <= @EndTime
UNION ALL
SELECT DATEADD(minute, 5 ,t.date) AS [date]
FROM dates t
WHERE DATEADD(minute, 5, t.date) <= @EndTime
I have the above sql, in this I'm using the 2 variables and calling @Starttime Variable couple of time. How should I build the SSIS package based on this query? how can I call the same variable in different place? how will SSIS take it?
Thanks

Since you have the variables set in code you just can place this code into the SQL code section of say an OLEDB source

How to play one clip multiple times at the same time?

I am writing a little game where a certain sound has to be played quite frequently. I load it as a Clip and play it with
myClip.setFramePosition(0);
myClip.loop(0);If the sound has to be played again but is still being played by another event, the setFramePosition() method resets the sound and the first playing instance is cut off.
A workaround would be that each object that needs to play this sound would get its own copy, but that is not feasible due to heavy memory consumption.
So here it goes: How can I play a single sound multiple times at the same time? Is that possible?

So here it goes: How can I play a single sound multiple times at the same time? Is that possible?Ummmm, if you're using a clip, you'll have to maintain one copy per object that needs to play the sound concurrently. You could keep one master copy, and then create copies of the clip as necessary to play them, and then just dump the copies to decrease memory consumption.
A second idea would be to write your own Clip class. Esentially, all you would need to do is dump some sound data onto a TargetDataline to play it. It'll handle the buffering and playing at the correct speed itself. If that's all you did, you should be able to dump multiple times from the same instance and play it multiple times.
Obviously, that's just a theory. In practice, it may not work that way...

How to use substitution variables in sqlplus activity of process flow

I have a process flow that does nothing more than create a couple of packages that I cannot successfully deploy from OWB. A workaround, not something that I want to do, but currently there is not much time to adjust the packages so they can be deployed from OWB.
I can successfully create the packages from files that are present in a directory on the server. But the location (directory) is not the same in all cases (OTAP). So I thought to use an input parameter to the process flow (named TELLINGEN) and use that in the sqlplus activity.
I have created the parameter START_PATH with a default value.
I have added an sqlplus activity and placed the following into the PARAMETER_LIST variable of the activity:
?${Target.ConnectString}?@${TELLINGEN.START_PATH}/npl_dbug.pkg?
When I run the process flow I see the following in the output:
SQL*Plus: Release 10.2.0.3.0 - Production on Tue Mar 18 18:10:14 2008
Copyright (c) 1982, 2006, Oracle. All Rights Reserved.

SQL> SQL> Disconnected from Oracle Database 10g Enterprise Edition Release

With the Partitioning, OLAP and Data Mining options
It obviously connects to sqlplus but then cannot find the file. Presumably because the variable has not been substituted.
How can I persuade the activity to substitute the variable?
Kind regards,
Eric.

Have been reading around a bit and found the (a) solution:
I placed the following in PARAMETERLIST:
?${Target.ConnectString}?@${Working.RootPath}/base64.sql?
And it turns out ${Working.RootPath} is pointing to the location you can provide under the configure for the sqlplus activity in the process flow. Just as you have to provide the target destination as indicated here: Re: SQLPLUS Activity in Process Flow
From the documentation it was not immediately clear to me where Working.RootPath was pointing to.

Calling a vi multiple times makes the timer "crash"

I use a subvi for writing data from a profibusnetwork. In this vi I can set a timer for the "update" to write away the data. I use a global variable to remember the last time the writing was done. The problem I encounter here is that when I use this subvi multiple times only the data I want updated fastest will be written away.. My question is: Is it possible to use just this one vi multiple times instead of renaming it for every datasource I want to write away?
Thx in advance,

Use a while loop with an uninitialised shift register instead of a global,
and build it into a function marked "re-entrant". This way different data
exists in each different copy of it in the code.

Using same bind variable multiple times in Dynamic sql

Hi;
I have a query which uses same variable multiple times, is there a way I could use only one time that variable and it will take multiple times.
Query is;
execute immediate 'SELECT count(*) FROM x WHERE MONTH_ID = :VOMNTH_ID
UNION
SELECT count(*) FROM Y WHERE MONTH_ID = :VOMNTH_ID
union
SELECT count(*) FROM z WHERE MONTH_ID = :VOMNTH_ID ' using month1,month1,month1
What I want Just supply month1 only once.
Your help is appreciated.
VKM

the way suggested by Nigel worksI'm not sure what you intend to use the resultset for but remember that UNION will remove duplicates from the result set and could possibly sort it too. Even if that were not the case (for example if you used UNION ALL) Oracle does not specifically guarantee the order of resultsets.
If you are expecting the first row to contain the first count (and so on) then you might not get the answer you are expecting.

How can I have use the same div ID multiple times on the same page?

Okay so a problem I encounter a lot is that often times I want to use the same div ID several times on the same page. An example of this is when I'm creating table like designs.
Let's say for instance I create a div ID called 'product-container'. I want to use 'product-container' multiple times on the same page but if I do this it is improper XHTML and will throw errors in any XHTML validator (you are only allowed to use a div ID once on any XHTML page in order for it to be standards compliant).
Now the first option is that I could define 'product-container' in my CSS style sheet multiple times by doing something like this...
#product-container {
     width: 300px;
#product-container-2 {
     width: 300px;
#product-container-3 {
     width: 300px;
#product-container-4 {
     width: 300px;
What you will see there however is that it seems pointless to define the same ID numerous times over (just adding a number on the end) when each ID is the exact same thing and has the exact same attributes.
Now what I have noticed is that there are some sites out there who manage to have the same ID appear several times in the code but add a number to it just like above. The difference is that they only have one definition for 'product-cointainer' in their CSS document but in their actual XHTML code they have IDs for 'product-container' but with numbers on the end like 2,3,4,5, etc. It's almost as if JavaScript or some other code is automatically appending a number on the end of the ID so the validator won't consider the markup to be invalid, but yet it knows that it's using the same 'product-container' style that is contained in the CSS style sheet.
I hope I explained this correctly. I'm just hoping to find a way that I can put the same div ID on a page multiple times without having to define it over and over again in my CSS.
Any help is much appreciated!

Because it seems like by using a class you can't make this position as
well as you can by using an ID. Am I wrong?
An ID name can be used only one time per page. A class name can be used multiple times per page.

Using multiple timer in the same SessionBean

Hello,
Is it possible to use multiple timer in the same Stateless Session Bean. In my application a user can schedule some task to execute. To do so I was thinking of creating a Session Bean which would create calendar timer on user request and, when one of the timer expires, retrieve the task to execute thanks to the information stored in the timer.
When I tried the solution explained above, it seems that the @timeout method is synchronized on 1 timer. For example if I create a timer that will be executed every 10 seconds and another one executed every 30 seconds, the timeout callback is called every 30 seconds but 4 times.
My code looks like that :
@Stateless
@LocalBean
public class TimeManager {
    public void onUserRequest(ScheduleExpression expression) {
        Timer timer = timerService.createCalendarTimer(expression, timerCfg);
    @Timeout
    void timeout(Timer timer) {
        logger.log(Level.INFO, (String) timer.getInfo());
}Is there a way to do what I want?
Thank you

This doesn't make any sense to me. If i were to write a bunch of schemas for a particular applicaion, would
I have them all in the same namespace? You would normally have one schema that describes the information model associated with the one namespace that the different documents in your application use.
If so, why can't I load more than one in the same name space?The parser chooses the schema based on the namespace alone. There is no other information used to decide which schema to use, so you can only have one schema for the namespace.
They all have different root elements.You can have different root elements in the one schema.
I don't even need the namespaces, but I can't
figure out how to get rid of them (the schema isn't valid with out them according to XML Spy). You can set the schema explicitily before parsing, but not (AFAIK) set after parsing has begun, except by using the mapping of namespace to schema location.
I have also tried to use the external-noNameSpaceSchemaLocationproperty, but it doesn't seem like you can pass in an array of schemas to that one. It only expects a
String as the Object you pass in to setProperty. Yes, you can only validate a document against the one schema.
So, how can I load all my schemas so I don't have to reference them in the XML documents? Either combine your schemas so you have one schema for your namespace that validates elements which are defined in that namespace (the formal/correct way of doing it), or construct a filter that inserts a PI to point to the schema once the root element is opened (the pragmatic/bit of a hack way of doing it).

How to use Value Variable in Report Painter Column defined as Formula

Hi Gurus,
In report painter, how can I add one field (exchange rate) in selection screen, so that user can provide the exchange rate to be used, then execute the report, the exchange rate will used to multiple local currency amount.
The reason for this is we want use provided exchange rate to convert the amount from once currency to the other currency.
Alternatively I am studying the functionality of "Value Variable" and found that I can perform the task from this. I have created the value variable but when I am using the variable in Report Painter columns as "&ZVALVAR", system is giving me error. I read the help and it states that use the variable with "&" and do it as it is mentioned.
Can anybody suggest what I need to do to make it workable.
Thanks

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.

and in my PL/SQL function i give a query as
Q AS VARCHAR2(1000) := 'SELECT * FROM EMP
WHERE STATUS = :P_STATUS';
Is this correct. I Know that the above statement works when the LOV is an integer, but when i use a character LOV return value the above statement does not work. how can i get in the character LOV value.
Can someone help me please.

You must bind each thing seperately. That's the way cursors work.

execute immediate (insert_string) using (v_string)
how can I separate the values and ho to use it .Don't use execute immediate. Use the DBMS_SQL package instead and bind your values dynamically with loops to cover all the columns you need etc.
