Selecting specific data from an array controlled by a boolean array

Hi!
I am trying to select specific data from a string array. The string data should be auto indexed to a string array indicator, but I just want specific values to be placed in the new array.
A boolean array controls when data should be auto indexed to the new string array. Every time a true appears in the for loop, the string data should be placed in the new string array, but I have a problem. I manage to pick the specific data to place in the new array, but i also get empty strings in the array when I am not supposed to write to the array. Instead of empty strings, I want my string data to be "compact". So when bool number 3 in the array is true, I want that string data to be in row 1, and not row 3.
Can you help me sort this one out?
Best regards

Here is a different version that also changes the size of the array for the indicator when the value is changed. You could do as much as you want here.

dbo.Religon ON dbo.Employee.ReligonID = dbo.Religon.ReligonID
suppose i need to show all data from Employee table (NationalityName,BranchName,JobName) where
NationalityID =NULL OR BranchID=NULL OR JobID=NULL
WHAT I DO
Notes : I mean in topic(selecting all data from view not table
meaning i need to show all data in employee table by view
in case of forign key(any forign key)equal null

I think you need to change
FROM dbo.Nationality INNER JOIN
dbo.Employee ON dbo.Nationality.NationalityID = dbo.Employee.NationalityID
to
FROM dbo.Nationality
LEFT JOIN
dbo.Employee ON dbo.Nationality.NationalityID = dbo.Employee.NationalityID

I have several hundred text files that contain a bunch of information. I only need six values from each file and ideally I need them as columns in an excel file.
How can I use Automator to extract specific Data from the text files and either create a new text file or excel file with the info? I have looked all over but can't find a solution. If anyone could please help I would be eternally grateful!!! If there is another, better solution than automator, please let me know!

You may try the following AppleScript script. It will ask you to choose a root folder where to start searching for *.map files and then create a CSV file named "out.csv" on desktop which you may import to Excel.
set f to (choose folder with prompt "Choose the root folder to start searching")'s POSIX path
if f ends with "/" then set f to f's text 1 thru -2
do shell script "/usr/bin/perl -CSDA -w <<'EOF' - " & f's quoted form & " > ~/Desktop/out.csv
use strict;
use open IN => ':crlf';

Select max date from a table with multiple records

I need help writing an SQL to select max date from a table with multiple records.
Here's the scenario. There are multiple SA_IDs repeated with various EFFDT (dates). I want to retrieve the most recent effective date so that the SA_ID is unique. Looks simple, but I can't figure this out. Please help.

Hi,
Welcome to the forum!
Whenever you have a question, post a little sample data in a form that people can use to re-create the problem and test their ideas.
For example:
CREATE TABLE     table_x
(     sa_id          NUMBER (10)
,     char_type     VARCHAR2 (10)
,     effdt          DATE
,     char_val     VARCHAR2 (10)
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0000651005, 'BASE',    TO_DATE ('15-AUG-2007', 'DD-MON-YYYY'), 'YES');
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0000651005, 'BASE',    TO_DATE ('13-NOV-2009', 'DD-MON-YYYY'), 'NO');
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0010973671, 'BASE',    TO_DATE ('20-MAR-2008', 'DD-MON-YYYY'), 'YES');
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0010973671, 'BASE',    TO_DATE ('18-JUN-2010', 'DD-MON-YYYY'), 'NO');
COMMIT;Also, post the results that you want from that data. I'm not certain, but I think you want these results:
`    SA_ID LAST_EFFD
    651005 13-NOV-09
10973671 18-JUN-10That is, the latest effdt for each distinct sa_id.
Here's how to get those results:
SELECT    sa_id
,         MAX (effdt)    AS last_effdt
FROM      table_x
GROUP BY sa_id
;

How to full restore OS X state to a specific date from Time Machine backup?

Hello! Could someone please advice how to restore the state of my iMac to a specific date?
NOT to the latest backup?

The only way I found to make a full restoration of OS X to specific date from a TM backup is to launch OS X in recovery mode (Cmd+R during startup) and then choose "Recover from Time Machine". Full restoration took approx 2 hours.
Dislike it very much. During my being a Windows user I could roll back in a matter of minutes with system utilities

HR Form do not select any data from specific Period

Hi All
I am facing issues on the HR FORMS for Brazil related to the Remunaration Statement
When I try to select any employee from a specific period (before April 2012), the system does not select any data.
From April 2012 until the current period and I could select the data and print the Form
I do not believe that is related to the Master data from the Employee, since it is always related to the same period, I guess it is on the HR Form configuration, retricting the period anywhere, but I could not find it
do you know any idea on how to fix it ?
Regards

Hi Steve,
In SQL Server Analysis Services, we can hide or disable hierarchy level by using
AttributeHierarchyEnabled property, however, when this property is set to false, this level will not appear no matter if contain data or not. In your scenario, you want to hide the hierarchy level dynamically, right? As Aleksandr
said, I am afraid there is no such a method to achieve it.
If you have any concern about this behavior, you can submit a feedback at
http://connect.microsoft.com/SQLServer/Feedback and hope it is resolved in the next release of service pack or product. Your feedback enables Microsoft to make software and services the best that they can be, Microsoft might consider to add this feature
in the following release after official confirmation.

Selecting certain data from Array

Here is the issue I am faced with.
I am currently using an HTTPService call to a PHP document
that builds XML. I then take that XML and place it into an Array,
(pretty basic as you can tell.)
What I am dealing with is that I have 15 tabs that all
contain similar "notes" sections. I would really like to run 1
HttpService that returns all of the data form the notes, (note
data, username of note) and then placing the appropriate notes data
to the appropriate tab and data grid container.
So I didn't know if there was a way you could select only a
certain part of an Array and then populate a datagrid with that
particular data?
Almost like cutting pieces of a large array out and
displaying thos pieces on different tabs.
Any help is appreciated.

Array has many functions that you can use to do pretty much
anythin goyu eant on it,
filter () method
AS3 function filter(callback:Function, thisObject:* =
null):Array
Executes a test function on each item in the array and
constructs a new array for all items that return true for the
specified function. If an item returns false, it is not included in
the new array.
map () method
AS3 function map(callback:Function, thisObject:* =
null):Array
Executes a function on each item in an array, and constructs
a new array of items corresponding to the results of the function
on each item in the original array.
etc .. look up in API documents it has examples too :

Module pool transfer of data from one table control to another

Hi all,
I have been assigned to module pool object wherein i have to display table control on screen and that table control contains only 10 rows on screen for display. Now my internal table it_out has 15 rows
Describe table it_out
line v_l.     " v_l = 15.
There is a pushbutton below table control and when i select multiple rows and click on that pushbutton it will navigate me to the next screen containing another table control on which i need to display those selected records.
Now the problem is that when i select first record and move cursor down to select last record then i am seeing only last record on next screen table control. why is it happening? please provide me with solution. For rest of cases it is working fine for example if i select first record and second record then i am seeing both these selected records on next screen table control . Only the problem arises when i tried to select first and lets say last record when scrolling down on table control.
I think the problem is with scrolling but when i loop on next screen with moved records i am seeing that 2 records are their but it is transferring only one record to next screen not the last one.
Your response is highly appreciated.
Thanks
Parag

Hi Parag,
Screen 8002 (with table control) --> select records --> press a button --> move to screen 8003 --> display selected records in screen 8002.
First problem that if you select first record in table control and scroll to end to select the last record, the first record in deselected.
Next problem, that if you select say 3 records in table control you want the to be displayed in another table control, the use this code.
Also take another internal table and work area same as the initial internal table and work area used in screen 8002.
On screen 8002, take a button with function code 'PROCESS', on which user clicks the screen 8003 should display selected records.
Now, use this code, its working:-
Take the names of the input/output fields as work_area-field_name and select column in table control as work_area-flag.
Also take a flag field of size 1 datatype character as the last field in the internal table and work area while declaration.
You must have passed a code in PBO of the screen for reading internal table into the table control.
So it reads the internal table into the table control whenever you perform any action on use command.
All you need to do is to write a code to modify the internal table form the table control while performing any user action.
Remember to change the LINE SEL option in attributes of table control as MULTIPLE.
At Screen Logic:-
PROCESS BEFORE OUTPUT.
MODULE status_8002. "for pf-status

    MODULE pass_data. "to pass data into table control from internal table

    MODULE modify_data. "to modify data from table control into internal table

In PBO,

      ENDIF.
ENDCASE.
"modify records from table control into the internal table
ENDMODULE.                 " PROCESS_DATA INPUT
Now if you select some records in this table control the values will retain in internal table.

Displaying data from a Database control

          I'm retrieving data from a sybase database into a java class and then pass that
          through to my jsp page. This works fine, as long as the sql actually returns a
          value (This specific query only returns one or none records).
          If no records were found, my jsp page displays an error message "Caught exception
          when evaluating expression "{pageFlow.m_dates.mon_am_loc}" with available binding
          contexts [actionForm, pageFlow, globalApp, request, session, appication, pageContext,
          bundle, container, url, pageInput]. Root cause: knex.scripting.javascript.EvaluatorException:
          The undefined value has no properties."
          the call in my .jsp looks as follow : <netui:label value="{pageFlow.m_dates.mon_am_loc}"
          escapeWhiteSpaceForHtml="false"/>
          .... and is part of a repeter item tag.
          Any help would be appreciated.

Can one Sync select apps data from say a desktop G5 to a MBP?

I was wondering if iSync has the ability to sync certain apps data between a traveling MBP laptop and my everyday home desktop G5?
For example, I want to just sync very specific things like:
-my Captain FTP data so I can keep FTP data current on my laptop as it is my desktop where I mess with it most
-1Password data so my updated 1Password access data from my daily desktop can get sync'd over to a MBP
-Entourage User Identity "database"
these are just examples and I am not even sure iSync is designed to do this type of sync and, can you even select what it syncs?
if not, any other ideas other than just manual slow carry-over via target Disk Mode.

No, iSync is only for syncing Contacts and Calendars between Address Book / iCal and non-Apple mobile phones.
Google "ChronoSync" for something that may do what you want.

How to select specific element from a XML document using JDBC?

Hi all,
I have a problem with selecting specific XML element in Oracle 11g release 1 from my java application. Data are stored in object-relational storage.
My file looks like:
<students>
<student id="1">
</student>
<student id="2">
</student>
<student id="3">
</student>
</students>
I need to select a specific <student> element. I've already tried few ways to achieve my goal but I failed.
SELECT extract(OBJECT_VALUE,'/students/student') FROM students - works fine, but this selects all <student> elements
SELECT extract(OBJECT_VALUE,'/students/student[1]') FROM students - which should select first <student> element works too but it causes exception when using JDBC driver returns:

SELECT to_clob(extract(OBJECT_VALUE,'/students/student[1]')) FROM students - in this case I hoped that DB would convert result to CLOB but the element is quite large (definitely more than 4000 Bytes long which I find out from forum is limit). But this exception occurs:

This behaviour raises two questions:
1) Why SELECT extract(OBJECT_VALUE,'/students/student') FROM students works but SELECT extract(OBJECT_VALUE,'/students/student[1]') FROM students does't ?
2) Is there any way how I can select specific element (element XPath /students/student[@id="some value"]) and convert it to String?
Thanks for your responses I would appreciate any suggestion

To be exact my <student> element is a bit complicated and looks like the one at the end of this post (sorry but it's in czech). And I need to select whole xml fragment (all opening and closing tags included) as it is shown. Maybe I used wrong solution and I should use CLOB storage. I discuss this issue here: Which solution for better perfomance?
Thanks anyway for your response. I would be very grateful if you have any further idea

How to delete a single data from table using control file

Edited by: 977940 on Dec 19, 2012 9:00 PMWhy?
And how do you imagine this happening with sqlloader?
The entire purpose of sqlloader is to load data (hence, the name sql*loader*) into a table from an external source. If you want to delete rows from a table, you use the sql DELETE statement.
What is the business problem you are trying to solve?

Selecting specific data from an array controlled by a boolean array
