Pls answer this interview question?
Hi,
i have attended the interview over the past few months ago so that they are asked
like
question 1)
a table has 1million rows because that will take more time to retrieve user says to improve the performance of that table .... in which way you would handle in PLSQL programming or concept anyway..
Pls revert back to me if you know anything about..............
Bluntly put. I will tell that user that he/she has no concept about performance or tables and instead of telling me how to do my job ("make that table faster!"), to explain his/her business requirement in order for me to build a technical solution that satisfies that requirement.
Of course, I will do that more diplomatically in an interview.
I can guess what the interviewers were after - they were probing PL/SQL expertise ito making PL/SQL code faster. E.g. using bulk processing to reduce context switching, or (my favourite) to reduce PL/SQL and increase SQL.
But they are missing the fact that
a) the size of the table does not determine performance
b) the amount of I/O does
The amount of I/O is directly relates to:
i) the structure of the table
ii) the amount of data requested in the SQL selection and projection
But no user gets away with telling me to "improve performance of a table". I do not take such input kindly. I do not tell a user or manager how they must perform their duties. I expect the same courtesy from them. Tell me the problem and I will do my best to create an optimal technical solution for it. But an and end-user, don't be so arrogant to tell me what technical solution to implement.

mat 26 May 2049 07:17:00
kris 26 May 2149 07:17:00 (because of using rr)
about rr format it says-if the current century is in range 50-99 and the entered century is in range 0-49 then the recorded date would be in the century next to the current one.
--pls help me out.ThanxThe RR datetime format element is similar to the YY datetime format element, but it provides additional flexibility for storing date values in other centuries. The RR datetime format element lets you store 20th century dates in the 21st century by specifying only the last two digits of the year.
If you use the TO_DATE function with the YY datetime format element, then the year returned always has the same first 2 digits as the current year. If you use the RR datetime format element instead, then the century of the return value varies according to the specified two-digit year and the last two digits of the current year.
That is:
If the specified two-digit year is 00 to 49, then
If the last two digits of the current year are 00 to 49, then the returned year has the same first two digits as the current year.
If the last two digits of the current year are 50 to 99, then the first 2 digits of the returned year are 1 greater than the first 2 digits of the current year.
If the specified two-digit year is 50 to 99, then
If the last two digits of the current year are 00 to 49, then the first 2 digits of the returned year are 1 less than the first 2 digits of the current year.
If the last two digits of the current year are 50 to 99, then the returned year has the same first two digits as the current year.
The following examples demonstrate the behavior of the RR datetime format element.
RR Datetime Format Examples
Assume these queries are issued between 1950 and 1999:
SELECT TO_CHAR(TO_DATE('27-OCT-98', 'DD-MON-RR') ,'YYYY') "Year"

Hints on this Interview Question?
Hints on this Interview Question?
If after a failed BW interview, the interviewer hints to me, getting another 2 to 3 full implementations under your belt in a R/3 environment
1. What do you really think she is referring to? Since this was for a BW position, is she referring to the extraction stuff on the side of R/3 to pull data to BW?
2. Could she be referring to actually knowing R/3 say SD, MM, FI/CO, which has nothing to do with BW?
If so, any hints on getting another 2 to 3 full implementations under your belt in a R/3 environment in the absence of internship or job to gain this experience?
Any other way to pick this up?
3. By the way, are there any blueprints or documented full cycle implementations which I can read and test on an R/3 system, which I have access to?
Thanks.Hi Caud,
obviously the interviewer was looking for "experience". No need for hinting at that.
This means that you have done things before hands-on rather than just read about it. The easiest starting point is the BI content. Take some application area you or prospective clients are most interested in and activate the content. Then start extracting data and following the data flow until you get the reports working and the data reconciles.
There are many books on SAP BW and all areas of R/3. But you can find many things online as well (help.sap.com).
There's also the best practices area that covers the full implementation cycle: http://help.sap.com/content/bestpractices/crossindustry/bestp_crossindustry_bi.htm

15. what are the different types of performance techniques?
16. can we do modifications on output of ALV reports, how?
17. what are the classes that are used in ALV reporting?hi bhushan,
1. What is the difference b/w classical report and ALV report and in classical report can we produce output more than 255 characters?
Ans. Classical report ---Consist of one program that create a single list.This means that when list is displayed,it has to contain all data
requested,regardless of the number of details the user wants to see.This procdeure may result in extensive and cluttered list from which the user has to pick the relvent data.(desired selection much be made before hand).
Mian thing in classical report is it is not interactive(you will have cluttered information).
Alv report _ IS interactive reporting (it is a set of function modules).(in alv we use both classical and interactive).
in classical report we can't produce output more than 255 characters(but in ALV we can have the report contains columns more than 255 characters in length).
ALV is very efficient tool for dynamically sorting and arranging the columns from a report output.
2. Did you used classes to create ALV reports and how is superior over using function modules in ALV report generation?
Ans. its upto you(did you use classes in ALV then say yes)
3. If we don't know the exact number of blocks to be generated then Can we generate the output with different number of blocks in
ALV reports?
4. In report if we have write statements in initialization, top of page and in start of selection then which event is first excuted and what
is the output?
ANS. TOP_OF_PAGE is triggered.
this event is triggered with the first WRITE statement or whenever new page is triggered. if you donts have any write statement before top-of-page or
in start-of-selection then this event is not triggered.
5. In interactive report what is the use of exit key word?
Ans.
6. what are nested structures and deep structures?
7. how can we write BDC program to upload data from CSV, XL, TAB delimeter type flat files?
Ans use FM 'GUI_UPLOAD'(CSV/TAB is .XLS)
CALL FUNCTION 'GUI_UPLOAD'

FILETYPE = 'ASC'
HAS_FIELD_SEPARATOR = ' '
HEADER_LENGTH = 0

Re: BDC - Header with multiple line items.
Posted: Sep 18, 2006 6:53 PM in response to: sap innova Reply E-mail this post
http://www.sap-basis-abap.com/abap/handling-table-control-in-bdc.htm
http://www.sap-img.com/abap/bdc-example-using-table-control-in-bdc.htm
When you have enter multiple line in BDC for a table control use call transaction tcode using i_bdcdata options from opt message into i_messages.
Check the below example.
data: lws_cnt type char2,
lws_field type char15.
LOOP AT i_invoicing_plan INTO wa_invoicing_plan.
lws_cnt = sy-tabix.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
EXPORTING
input = lws_cnt
IMPORTING
output = lws_cnt .
CONCATENATE 'FPLT-AFDAT(' lws_cnt ')' INTO lws_field.
CONCATENATE wa_invoicing_plan-date+6(2)
wa_invoicing_plan-date+4(2)
wa_invoicing_plan-date+0(4) INTO lws_date
SEPARATED BY '.'.
PERFORM bdc_field USING lws_field lws_date.
CONCATENATE 'FPLT-FPROZ(' lws_cnt ')' INTO lws_field.
lws_perct = wa_invoicing_plan-percentage.
CONDENSE lws_perct.
PERFORM bdc_field USING lws_field lws_perct.
ENDLOOP.
While calling the transaction give like this:
DATA: opt TYPE ctu_params.
opt-dismode = 'N'.
opt-updmode = 'A'.
opt-defsize = 'X'.
CALL TRANSACTION tcode
USING i_bdcdata OPTIONS FROM opt MESSAGES INTO i_messages.
LOOP AT i_messages.
ENDLOOP.
9. In call transaction and session method which method is prefered one?
Ans. it depends on data if data is small then go for call transaction method.
10. why can't we use call transaction method to upload large amount of data?
Ans.there are chances of many errors.
11.what is the use of standard text in sap scripts, why can't we hard code the same information in form itself?
Ans.Assume ur company has stored some text which will printed on sapscript based on certain conditions and not taken thru driver program .
For eg .for a plant 1000
You have to print 'Plant is 1000 and stock is 1000'.
for plant 1010
You have to print 'Plant is 4000 and stock is 3000'.
Then you will create a standard text thru SO10 create a text name and id would be ST and language as EN .
AND YOU PLace the text You have to print 'Plant is 1000 and stock is 1000'.
and this will create one standard text and another standard text for another .
then in the sapscript you will check the plant
use the command in the sapscript and write
Include text name 'zzz' id ST lanuage en.
When you execute
Sapscript will read the include and bring the text from SO10 and print on the screen .
Check T-Code NACE
Check link for more on SAP Scripts.
http://www.sap-img.com/sapscripts.htm
12.what are user exits and how can we create them?
User exits -> They are the provisions given by the sap standard program to add some extra functionality to their program .
Which will be present till there is any version change .
1. User exits were nothing but
subroutines
FORM/PERFORM
called from standard programs.
2. The FORM defintion was placed inside
an empty include file.
3. So It was called EVERYTIME.
and we need to MODIFY/REPAIR the
standard include .
USER EXITS
1. Introduction:
User exits (Function module exits) are exits developed by SAP.
The exit is implementerd as a call to a functionmodule.
The code for the function module is writeen by the developer.
You are not writing the code directly in the function module,
but in the include that is implemented in the function module.
The naming standard of function modules for functionmodule exits is:
EXIT_<program name><3 digit suffix>
The call to a functionmodule exit is implemented as:
CALL CUSTOMER.-FUNCTION <3 digit suffix>

13. can we modify the sap provided code?
Ans. Yes,but you need to have access key and i thing you need to have permission also.
14. what are oss notes?
ans.SAP provides support in the form of Notes also and this is called OSS. Can check the link Sree provided.
Just for an example if you face any error in your system. Then there is error number associated with the error. Then you can search for the OSS not for the error number, and the note will give you possible solution to your problem.
You do have notes for any details for every thng and any thing related to SAP.
ans.YES! It is Online Suppor System from SAP. It is official.
Search in http://service.sap.com support portal link with keywork 'OSS' / 'OSS User Guide' to get more info and 'how to' guides.
OSS (online support system) .You can get this support from WWW.SAP.COM site..SAP will issue OSS userid and password to the customers with each licence to their packages..Here you will get all suppost packages information and how to use the things..These kind of info you will get it..Ask your Project customer about this id.. OSS1 is the transaction code to check the oss notes from SAP...
15. what are the different types of performance techniques?
Ans. Use se30--- simply gives you an over view of the time spent on the application processing against the time spend selecting from the database.
use sto5 _SQL trace tool ---Overview of exactly how the prog is hitting against the database and shows you the individual SQL statements used with which index was used.
16. can we do modifications on output of ALV reports, how?
ans.
17. what are the classes that are used in ALV reporting?
ans.Check out this tutorial
An Easy Reference for ALV Grid Control.pdf
and also demo programs in your system.

Some problems in finding answers of interview questions Oracle SOA 11g
hi
These questions were asked from me in an interview. could someone please help me to get the answers?
Q1: While using a file adapter if we have declared an elements schema length as 100 and file reading the file adapter that element contains 120 characters, then what will happen ? Is there any way to read that file?
Q2: In a BPEL process there is a partner link which is invoked more than once in this BPEL. While creating assertions in Test suit for this composite how we will write assertions for this partener link?
Q3: In a Flow activity if we have added 2 assign activities in each branch, then will we really have performance improvement as compared if we use them serially?
Q4: In OSB how to restrict the no of messages coming to Proxy service?
Q5: in OSB how to use dynamic URL of business service? (we will get to know the url at rum time or we have to create url at runtime)
Q6: While using fault policy framework if have set the retry count as 3. Now when the retry count is exhausted then how this fault will be clost.faulted or open.faulted?
Q7: can we have two service bindings in one composite if there is only one BPEL process in that composite?
Q8: Q: If we need to validate any message in OSB after pipeline stage according to its destination

Could you pls answer thisHi
All this AT NEW, AT FIRST, AT END OF and AT LAST are called control break statements of Internal tables and are used to calculate the TOTALS based on sertain key fields in that internal table
FIrst to use these statements the ITAB has to be sorted by the key fields on whcih you need the SUM of the fields.
Some time you will get * when moving data from this int table to other table using these commands
so you have to use
READ TABLE ITAB INDEX SY-TABIX in AT..ENDAT..if you are using other fields between them

BDC
BDC:
Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
Features :
BDC is an automatic procedure.
This method is used to transfer large amount of data that is available in electronic medium.
BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
BDC uses normal transaction codes to transfer data.
Types of BDC :
CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
BATCH INPUT METHOD:
This method is also called as CLASSICAL METHOD.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
Features:
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.
Differences between Call Transaction and Sessions Method:
Session method.
1) synchronous processing.
2) can tranfer large amount of data.
3) processing is slower.
4) error log is created
5) data is not updated until session is processed.
6) generally used for back ground jobs.
7) at atime we can update to more than one screens.
Call transaction.
1) asynchronous processing
2) can transfer small amount of data
3) processing is faster.
4) errors need to be handled explicitly
5) data is updated automatically
6) for background n fore ground jobs.
7) at atime we can update to a single screen.

SiriHi Siri,
1. Analysis Process designer
The Analysis Process Designer (APD) is the application environment for the SAP data mining solution.
The APD workbench provides an intuitive graphical interface that enables you to visualize, transform, and deploy data from your business warehouse. It combines all these different steps into a single data process with which you can easily interact.
Use APD to pre-process your data:
? Read data from different sources and write it to a single location
? Transform data to optimize reporting
? Ensure high data quality by monitoring and maintaining the information stored in your data warehouse.
The APD is able to source data from InfoProviders such as InfoCubes, ODS objects, InfoObjects,
database tables, BW queries, and flat files. Transformations include joins, sorts, transpositions, and with
BW 3.5, integration with BW?s Data Mining Workbench (RSDMWB).

This Web item can be used to manage consistent sections of different Web templates centrally within one Web template, which you can then insert into any Web template as required. In this way, you can define a header or footer section with the corporate logo and heading as a Web template and can integrate this Web template into your Web applications as a Web Template Web item. This Web template is then inserted during runtime. In contrast to HTML frame technology, the system does not generate a new page during this process. The context of the main template thus remains the same. In this way, you can display text elements and so on from data providers for the main template in the inserted Web template.

Can't anyone answer this simple question?
Guys,I want to know whether a GUI which is made using Swing can write files to disk,or ,in another way--does Swing support writing files to disk?(This is becoz applets do not support this feature)
Thannks in advance,
Avichal167One thing to note...
Because the previous example is simple, I handled all the File IO operations in the same class as the GUI ...
You can how ever have the File IO done in a different class and tie it in to your GUI class...
Example... GUISample.java
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class GUISample extends JFrame implements ActionListener{
private JTextArea jtxArea;
private JButton jbtn;
private String[] bText = {"Read","Write"};
private boolean bState = true;
private FileHandler handler;
public GUISample(){
super("GUI Sample");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLayout(new BorderLayout());
jtxArea = new JTextArea(15,20);
jtxArea.setEditable(true);
jbtn = new JButton(bText[0]);
jbtn.addActionListener(this);
getContentPane().add(jtxArea,BorderLayout.CENTER);
getContentPane().add(jbtn,BorderLayout.SOUTH);
pack();
setVisible(true);
handler = new FileHandler(); // instantiates FileHandler
/* both method from FileHandler return Strings to be displayed in the JTextArea */
public void readAndDisplay(){
jtxArea.setText(handler.readTheFile()); // calls method from FileHandler
public void writeToFile(){
jtxArea.setText(handler.writeTheFile(jtxArea.getText())); // calls method from FileHandler
public void actionPerformed(ActionEvent ae){
if ((ae.getSource() == jbtn)&&(bState)){
bState = false;
jbtn.setText(bText[1]);
readAndDisplay();
else{
bState = true;
jbtn.setText(bText[0]);
writeToFile();
public static void main(String[] args){
GUISample gspl = new GUISample();
}Example... FileHandler.java
import java.io.*;
public class FileHandler {
private String theData;
public String readTheFile(){ // reads and returns data or message
try{
File afile = new File("test.txt");
FileInputStream fis = new FileInputStream(afile);
try{
byte[] strBuff = new byte[(int)afile.length()];
fis.read(strBuff);
try{
theData = new String(strBuff);
fis.close();
}catch(NullPointerException npe){theData = "Null Pointer Exception";}
}catch (IOException ioe){theData = "IO Exception";}
}catch (FileNotFoundException fnfe){ theData = "File Not Found";}
return theData;
public String writeTheFile(String data){ // writes and returns a message
try{
File afile = new File("test.txt");
FileOutputStream fos = new FileOutputStream(afile);
try{
try{
fos.write(data.getBytes());
fos.close();
theData = "File Saved";
}catch(NullPointerException npe){theData = "Null Pointer Exception";}
}catch (IOException ioe){theData = "IO Exception";}
}catch (FileNotFoundException fnfe){theData = "File Not Found";}
return theData;
}and of course you can use the same Test.txt file...
As you can see from this example, I have one class create and handle the GUI and the second class handles all the File IO operations...
So to better answer your first question, Swing and AWT and Applets can be used to create GUIs... and as far as File IO, all three can have code or be couples with a class that does File IO operations...
The only restriction is with Applets where by default the SecurityMananger does not allow File IO operations...
Notice the word "default", this means Applets are capable of doing File IO, if you do some extra coding and policy work... ( my terminology may be off on this)
But as stated earlier, I am not well versed enough in Applets to give you assistance in creating a Signed Applet that can... soon I will, just not at this time...

Pls answer an simple question.........
can someone tell me what's the meaning of jdbc.oracle.oci8...,
how can load the driver?
i used like this--
import oracle.java.driver.*;
Class.forName("oracle.jdbc.driver.OracleDriver");
......DriverManager.getconnection
("jdbc:oracle:oci8:bpm/bpm:@jank:1521:jank")
it's same that something wrong with the above code!
Is jdbc.oracle.oci8... (fat driver) a pure java driver?
i'm not sure of that, cause i have no help docs and just being a beginner.pls give u hand......Hi,
The JDBC URL is usually of the format jdbc:subprotocol:subname
i.e In this format, this url identifies an individual database in a driver specific manner. Different drivers may need different information un the URL to specify the host database.
For example Oracle JDBC- Thin Driver uses a URL of the form of
jdbc:oracle:thin:@dbhost:port:sid; and teh JDBC-ODBC bridge uses jdbc:odbc:datasourcename;odbcoptions
So the format of the url is specific to the type of driver you are using..it may be a oci driver , thin driver or any.
Coming to ur question,
First by specifying ur driver name in Class.forName makes your driver class to get loaded your application's JVM.
Then you would get a connectuoin from the DriverManager using getConnection method().
can someone tell me what's the meaning of jdbc.oracle.oci8...,
how can load the driver?
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con = DriverManager.getconnection
("jdbc:oracle:oci8:@jank:1521:jank","bpm","bpm") where the first parameter is the driver specific url and second and third ate username and password to the database you are trying to connect to.
You can refer material in Sun's Javasoft.com and look for jdbc materials to study in detail.
Hope this helps. Also Look what Java error you are getting, while compiling. May be the driver class you are trying to load is not in the Classpath.
Thanks

I've had an iBook G4 since November and this question has been killing me ever since: What are the two little hinged corner pieces on the charger for???
When I plug my iBook into the wall, the module that actually plugs into the wall has two little corner pieces that swing out, almost like hooks. What are these for?!?!?!
This very serious question has plagued me from day one. Thanks!Wow... Thanks for that enlightenment.... I never even considered the possibilities of the charging module...

Hi,
I have the name of the method in a String format. I want this information to get evaluated as a method/function. How can I do that?
For example, I have a string named "setName" and another string "str". I want this information to get evaluated as :- setName(str), ie. string 'setName' should get interpreted as a method name 'setName( )'. 'setName(String str)' is a method in the same class.
Thanks!

As you can see TAB is a *view* that is owned by the SYS user and is actually a view on the data dictionary of the database.
AND ARE THE TABLES,THAT WE CREATE UNDER "TAB" TABLE, THE ROWS OF "TAB" TABLE?"..OR IT CAN BE PUT LIKE "CAN WE CALL THE Tables created inside tab as rows of tab table?"You don't create tables under the TAB view. You create tables in your schema and the TAB view will show you the tables that exist/are owned by your schema.
The view, as with any view, when queried, returns rows showing the table names.
...please answer ....i need it badly!! :(Everyone wants their question answering. Why should your question take any priority over anybody elses, just because you want it badly. I'm sure if we asked the other people with questions they would also like an answer badly, but they aren't so rude as to expect people drop their own work just for them.
