Empty query result into variable? what's the result

It's Null Value or What?
i write a query like this.
select name into variable from table where pk is null;
/*this query return nothing*/
/*Variable = Null or variable is empty ?*/

Generally, the contents of the variable do not change if a SELECT..INTO.. returns no rows.
It is safer to have your NO_DATA_FOUND exception handler set the variable to an appropriate value (eg null).

What is the result of using the "post tax payable" option in the advance ta

what is the result of using the "post tax payable" option in the advance tax report - program rfumsv00? I know it will then post the input and output tax to the tax payable GL account. But from point of view of reporting, when you run the advance tax report, will there be any change after doing this posting to tax payable account?

Basic communication aside, J2EE is mostly a synchronous run-time environment. When asynchrony is introduced, a whole new set of infrastructure requirements is needed to support QoS and commercial-quality implementations. In other words, it's not just about API anymore, it's about reliable communication, exception handling, time outs, etc. You may want to look at this Q&A to see some of the benefits provided by J2EE as underlying run-time for orchestration:

Apex report result doesn't agree with the result of sql developer

Hello guys,
at the moment I try to create a standard report which takes his content from several spreadsheets. Because of some problems with the searchbar I'm not able to use an interactive report. The sql query contains a function, which sets some space characters into the content of a column. But there is a big problem. When I call my sql query in apex from the spreadsheets the result doesn't agree with the result which affords the sql developer.
I know that the sql developer affords the right result.
best regards

thats the query:
select "TWORKITEM"."WORKITEMKEY",
"TWORKITEM"."PROJCATKEY",
"TPROJECT"."LABEL",
"TWORKITEM"."PACKAGESYNOPSYS",
replace(replace("TWORKITEM"."PACKAGEDESCRIPTION", chr(10), '<br>'),'<td></td>','<td></td>') packagedesc,
suche_ohne_ti_be("TWORKITEM"."WORKITEMKEY") "CHANGEDESCRIPTION"
from "TWORKITEM" "TWORKITEM", "TPROJECT" "TPROJECT", "TPROJCAT" "TPROJCAT"
where "TWORKITEM"."PROJCATKEY" = "TPROJCAT"."PKEY"
and "TPROJCAT"."PROJKEY" = "TPROJECT"."PKEY"
and (instr(upper("TWORKITEM"."WORKITEMKEY"), upper(nvl(:P10_SEARCHTEXT, "TWORKITEM"."WORKITEMKEY"))) > 0

SQL query with multiple tables - what is the most efficient way?

Hello I am learning PL/SQL. I have a simple procedure where I need to find number of employees and departments per location as per user input of location_id.
I have 3 Tables:
LOCATIONS
location_id (pk)
location_name
DEPARTMENTS
department_id (pk)
location_id (fk)
department_name
EMPLOYEES
employee_id (pk)
department_id (fk)
employee_name
1 Location can have 0-MANY Departments
1 Employee has 1 Department
Here is the query I came up with for PL/SQL procedure:
/*Ecount, Dcount are NUMBER variables */
SELECT SUM (EmployeeCount), COUNT(DepartmentNumber)
     INTO Ecount, Dcount
     FROM
     (SELECT COUNT(employee_id) EmployeeCount, department_id DepartmentNumber
          FROM employees
          GROUP BY department_id
          HAVING department_id IN
                    (SELECT department_id
                    FROM departments
                    WHERE location_id = userInput));
I do get the correct result, but I am just wondering if my query is on the right track and if there is a more "efficient" way of doing this.
Thanks in advance for helping a newbie out.

Hi,
Welcome to the forum!
Something like this will be more efficient:
SELECT    COUNT (employee_id)               AS ECount
,       COUNT (DISTINCT department_id)     AS DCount
FROM       employees
WHERE       department_id IN (     SELECT     department_id
                    FROM      departments
                    WHERE      location_id = :userInput
;You should also try a join instead of the IN subquery.
For efficiency, do only the things you need to do.
For example, you don't need a count of employees in each department, so don't compute one. That means you won't need the in-line view, so don't have one.
You don't need PL/SQL for this job, so don't use PL/SQL if you don't have to. (I realize this question was out of context, so you may have good reasons for doing this in PL/SQL.)
Do all filtering as early as possible. Don't waste effort computing things that won't be used .
A particular example of this is: Never use a HAVING clause when you can use a WHERE clause. What's the difference between a WHERE clause and a HAVING clause? The WHERE clause is applied before aggregate functions are computed, and the HAVING clause is applied after; there's no other difference. Therefore, if the HAVING clause isn't referencing an aggregate function, it could be done in a WHERE clause instead.

Variables: What's the difference between

I am reviewing and thinking about how I could have made a web
application I created more efficient in the future. I was
contemplating the use of variables so there would not have to be so
many different results pages and queries. What is the different
between the following variable types and perhaps a simple example
of each if anyone has one:
1. URL variable
2. Cookie variable
3. Session variable
4. Environmental variable
5. Form variable
6. Server variable
Thanks.

It would help if you were to say which server model you're
using, but in
simple terms, they each describe where the variable comes
from.
1. A URL variable is passed to a page through a query string
at the end
of the URL:
http://www.example.com/somepage.php?name=David
You access it in PHP as $_GET['name']
2. A cookie variable comes from a stored cookie:
$_COOKIE['name']
3. A session variable is one that is available in all pages
that are
part of a session: $_SESSION['name']
4. Environmental variables tell you information about the
server your
site is running on: $_ENV['variableName'] (not used very
often)
5. A form variable contains the contents of a form element
submitted
using the post method: $_POST['name']
6. A server variable gathers information about the script or
the server
that the script is running on: $_SERVER['SCRIPT_NAME']
contains the
current script's path

Why we use variables what are the advantages of variables

hi
can u tell me why we use variables and where we use variables
ashwin

hi Ashwin!
Variable are used for providing the parameters for a query at real time. that means we can dynamicall specify some what exalty the query should display in the query for example we can use a variable on the charectersitic like country so that we can decide the contents of the query to will be relavent to the countries we specified.
Advantages of using the varibles in a query are
1) we can build a single query which can be used by all. Ex:we can generate a report for all the customers seperatly by using a single query and just by changing the value in the variable at runtime
2) if we use the processing type authorization for a variable. We can limit the user from accessing the information which he is not authorised to see in the report. This will also make us personalize the query based on the user who is accessing the report.
Sap help on overview and usage and the types are given in the following link:
http://help.sap.com/saphelp_nw04/helpdata/en/f1/0a56a7e09411d2acb90000e829fbfe/frameset.htm

Parsing SOAP Results into Variables

Can someone assist me in figuring out what way I need to go
to parse SOAP results into an array?
I have setup the <MX:WEBService> correctly, created my
resultEvent(event) handler and faultEvenet(event) handler as
needed. Below is the web service:
<mx:WebService
id="srvGetTagHistory" wsdl="{SOAP_URL}"
result="CreateTagHistory(event)" fault="faultEvenet(event)"
useProxy="false">
<mx:operation name="GetTagHistory" resultFormat="e4x">
<mx:request>
<RSWID>{vRSWID}</RSWID>
</mx:request>
</mx:operation>
</mx:WebService>
This works perfectly. I can return the results of the
webservice to a text area control, and the complete SOAP results
are displayed.
My problem is I cannot and have not figured out how to make
the SOAP results into some type of arraycollection for using in,
lets say, a dataGrid.
Here is an example of a SOAP result for the above webservice:

Any assistance to this issue would be greatly appreciated.

If you have set resultFormat="e4x" than you can handle the
result very easily.
I guess you already find out that your result is in
event.result.
Your example is too hard to parse by human.

Regular expression result into variable??

Im dealing with log files here...i use regular expression to detect the values...how can i save these values into variable, for example 25-07-2005 into "date"?
this is how my output statement look like
myOutput1.print(matcher1.group(1));
matcher1.group is the way i use to get the value using regular expression

thanx...actually i have already match it in groups and it works fine..the problem is im dealing with log files...what im trying to do is reformat back the log files collected...example.."8 Nov" change it to 8-11-2005
When i match it into the group its actually just finding the pattern, not saving it into variable..if its save in the variable would be easier..
how can i change "8 Nov" to 8-11-2005?? can anyone help me with a simple code???
thanks

What is the result of violating the thread safety rule of Swing?

I needs to know what is the outcome of violating the thread safety rule of swing? memory leak? I have seen code violating the rule but still runs fine. Did anyone know?
Thanks

I had violated this rule and sometime it flies and sometimes it does a crash and burn. Most often it can result in a bug seen so rarely that it does not become a concern until the day of product roll-out. Mostly it can result in intermitent GUI anomallies and sometimes total app locks that are hard to intentionally reproduce. All paints and updates are done on the event queue and it is possible to invoke a thread on it saftly.
I refer you to the tutorial at: http://java.sun.com/docs/books/tutorial/uiswing/mini/threads.html
