2) Tell me some thing about SQL-LOADER.
Sql * loader is a bulk loader utility used
for moving data from external files into the oracle database.
Sql * loader supports various load formats,
selective loading, and multi-tables loads.

--The conventional path loader essentially loads the data by using
standard ‘insert’ statement.
2) direct
-- the direct
path loader (direct = true) by possess of logic involved with that, and loads
directly in to the oracle data files.
EX:-
My data.csv file
1001, “scott tiger”,1000,40
1002,”gvreddy”,2345,50
Load data
Infile ‘c:\data\mydata.csv’
Into table emp
Fields terminated by “,” optionally enclosed

* Additional address information can be populated in
RA_CUSTOMERS_INTERFACE_ALL.address_attribute1 to 15
This will go into RA_ADDRESSES_ALL.attribute1 to 15
And so on.
5. What should be the batch size (number of customer records) general
guidelines for optimal performance
About 10,000 records per bacth is ideal, it is suggested to keep the batch
size small.
6. Why does customer interface error out if there is mismatch
in address information?
Because the code validates against these mismatches.
arplscin.sql and arplbcin.sql
It validates the address being inserted or updated with respect to the
tax
location flexfield structure. For each row being inserted or updated
in
RA_CUSTOMERS_INTERFACE, and that has not already been marked in
error,
the set_location_ccid function is called to return either an existing
ccid
for the address entered or to create a new entry in AR_LOCATION_VALUES
for
this new address. The RA_CUSTOMERS_INTERFACE record is then updated
with the
value of the ccid
returned.
7. How do you send records at customer level profile and address/site
level profile?
For every customer record in RA_CUSTOMERS_INTERFACE_ALL, insert two
records in table RA_CUSTOMER_PROFILES_INT_ALL. (Refer

objects are moved against them.
Off: parent borders remain fixed when child
objects are moved against
them.
A placeholder is a column is an empty
container at design time. The placeholder can hold a value at run time has been
calculated and placed in to It by pl/sql code from anther object.
You can set the value of a placeholder column is in a
Before Report trigger.
Store a Temporary value for
future reference. EX. Store the current
max salary as records are retrieved.
23) What is Formula Column?
A formula column performs a
user-defined computation on another column(s) data, including placeholder
columns.
A summary column performs a
computation on another column's data.
Using the Report Wizard or Data Wizard, you can create the following
summaries: sum, average, count, minimum,
maximum, % total. You can also create a
summary column manually in the Data Model view, and use the Property Palette to
create the following additional summaries:
first, last, standard deviation, variance.
50) What is cursor?
A Cursor is a pointer, which
works on active set, I.e. which points to only one row at a time in the context
area’s ACTIVE SET. A cursor is a construct of pl/sql, used to process multiple
rows using a pl/sql block.
28) Types of cursors?
1) Implicit: declared for all DML and pl/sql statements.
By default it selects
one row only.
2) Explicit: Declared and
named by the programmer.
Use explicit cursor
to individually process each row returned by a
Multiple statements, is called ACTIVE SET.
Allows the
programmer to manually control explicit cursor in the
Pl/sql
block
a) declare: create a named sql
area
b)Open: identify the active
set.
c) Fetch: load the current row
in to variables.
d)Close: release the active
set.
CURSOR
ATTRIBUTES
a) %is open: evaluates to true
if the cursor is open.
b) %not found: evaluates to true
if the most recent fetch does not return a row
c) %found: evaluates to true
if the most recent fetch returns a row.
d) %row count: evaluates to the
total number of rows returned to far.
Example for cursor:
1) Declare
Vno emp.empno%type;
Vname emp.ename %type;
Cursor emp_cursor is
Select empno,ename
From emp;
Begin
Open cursor;
For I in 1..10 loop
Fetch emp_cursor into vno,vname;
Dbms_output.putline(to_char(vno) ||’ ‘||vname);
End if;
E nd;
2)
Begin
Open emp_cursor;
Loop
Fetch when emp_cursor %
rowcount >10 or
Emp_curor % not found;
Bdms_output_put_line(to_char(vno)||’ ‘|| vname);
End loop;
Close emp_cursor;
End;
CURSOR FOR LOOP
A) cursor for loop is a
short cut to process explicit cursors
B) it has higher performance
C) cursor for loop
requires only the declaration of the cursor, remaining things like opening,
fetching and close are automatically take by the cursor for loop
Example:
1) Declare
Cursor emp_cursor is
Select empno,ename
From emp;
Begin
For emp_record in emp_cursor loop
Dbms_output.putline(emp_record.empno);
Dbms_output.putline(emp_record.ename)
End loop
End;
Can we
create a cursor without declaring it?
Yes – by using cursor for loop using
subqueries.
BEGIN
FOR emp_record IN ( SELECT empno, ename
FROM emp) LOOP
-- implicit open and implicit fetch
occur
IF emp_record.empno = 7839 THEN
...
END LOOP; -- implicit close occurs
END;
a)
for update clause:
1) use explicit locking to deny access for the duration of a transaction
2) lock the rows before update or delete
Ex :
select …….
From…….
For update[ of column ref]
[no_wait]
b)
where current of clause?
1) use cursor to update or delete the
current row
Where current of <
column ref>
29) Attribute data types?
1) %type 2) %row type.
30) Exception Handilings?
Is a mechanism provided by pl/sql to detect runtime errors and process
them with out halting the program abnormally
1) pre-defined
2) user-defined.
PRE-DEFINED:
1) cursor_already_open--------attempted
to open an already open cursor.
2) Dup_val_on_index --------attempted to insert a duplicate
values.
3) Invalid_cursor -------- illegal cursor operation
occurred.
4) Invalid_number -------- conversion of character string
to number fails.
5) Login_denied ---------loging on to oracle with an invalid
user name
and password.
6) program_error -------- pl/sql has an internal
problem.
7) storage_error -------- pl/sql ran out of memory
or memory is
corrupted.
8) to_many_row ---------single row select returned
more than one row.
9) value_error --------
arithmetic,conversion,truncation or size
constraint error
occurred.
10) zero_devided -------- attempted to divided by
zero.
USER-DEFINED:
Declare : name the exception
Raise : explicitly raise
the exception by using the raise statements
Reference:
exception handing section.
The Raise_Application_Error_Procedure:
n You can use this
procedure to issue user-defined error messages from stored sub programs.
n You can report errors
to your applications and avoid returning unhandled exceptions.
Raise_Application_Error(error_number,message[,{true/false}]
Error number è between -20000 to -20999
pragma exception_init?
It tells the compiler to associate an exception with an oracle error. To
get an error message of a specific oracle error.
Ex: pragma exception_init(exception name, oracle error number)
Example for Exceptions?
1)
Check the record is exist or not?
Declare
E emp% rowtype
Begin
e.empno := &empno;
select * into e from emp
where empno =e.empno;
Dbms_output.putline(‘empno’ || e.empno);
Exception
When no_data_found then
Dbms_output.putline(e.empno
||’doest exist’);
End;
2) User defined exceptions?
Define p_dept_desc =’gvreddy’
Define p_dept_number =1236
Declare
E_invalid_dept
exception;
Begin
Update departments
Set
dept_name=’&p_dept_desc’
Where dept_id
=’&p_dept_number’;
If sql% not found then
Raise e_invalid_departments;
End if;
Commit;
Exception
When
e_invalid_departments then
Dbms_output.putline(‘no such dept’);
End;
52) what is REF Cursor?
To execute a multi-row
query, oracle opens an unnamed work area that stores processing information, to
access the information, an explicit, which names the work area or, a cursor
variable, which points to the work area.
where as a cursor always refers
to the same query work area, a cursor
variable can refer to a different work areas, cursor variable area like ‘c’ or
‘pascal’ pointers, which hold the memory location(address) of some object
instead of the object itself.
So, declaring a cursor variable creates a pointers, not an object.
32) Can u define exceptions twice in same
block?
No
33) Can you have two functions with the same
name in a pl/sql block?
Yes
34) Can you have two stored functions with in
the same name?
Yes
35) Can function be overload?
Yes
36)
What is the maximum number of statements that can be
specified in a trigger statement?
One.
32) Stored procedure?
Stored procedure is a sequence of statements that perform specific
function.
53) What is procedure?
---- is a named pl/sql block to perform a
specific task.
----
A procedure may have DML statements.
---- It may or may not return a value.
---- Procedure can return more than one value.
Example for procedure
1) To accept the year as
a parameter and list emp belong to the year?
Create or
replace
Procedure empy(y number) is
Cursor
emp_cursor is
Select * from
emp where to_char(hiredate,’yyyy’)=’y’;
Emp_record
emp%rowtype;
Begin
For
emp_record in emp_cursor loop
Print (emp_record.empno);
Print (emp_record.ename);
Print (emp_record.sal);
End loop;
End;
Output :
var empx number;
Begin
:empx :=
‘1234’;
End;
Exec empy(:empx);
Print empy;
54) What is function?
---- is a named pl/sql block to
perform a specific task, is mainly used for calculation purpose.
---- A function is called as
part of an exception.
---- Every function should
return a value
Example for function
Create or replace
Function get_sal(p_id in
emp.emp_no% type)
Return
number
Is
v_sal
emp.sal%type :=0;
Begin
Select
salary into v_salary
From emp
Where emp_no = p_id;
Return v_salary
End
get_sal;
End;
Output :
var g_sal number;
Exec :g_sal :=
get_sal(99);
Print g_salary;
9.Can functions be
overloaded ?Yes.
10.Can 2 functions have same name & input parameters but differ only by return datatype
No.
55) What is the package?
---- Group logically related
pl/sql types, items and subprograms.
1) package specification
2) package body
Advantages of a package:
·
Modularity
·
Easier Application
Design
·
Information Hiding
·
Overloading
You cannot overload:
•Two subprograms if their formal
parameters differ only in name or parameter mode. (datatype and their total
number is same).
•Two subprograms if their formal
parameters differ only in datatype and the different datatypes are in the same
family (number and decimal belong to the same family)
•Two subprograms if their formal
parameters differ only in subtype and the different subtypes are based on types
in the same family (VARCHAR and STRING are subtypes of VARCHAR2)
•Two
functions that differ only in return type, even if the types are in different
families.
56) What
is FORWARD DECLARATION in Packages?
PL/SQL allows for a special subprogram
declaration called a forward declaration. It consists of the subprogram
specification in the package body terminated by a semicolon. You can use
forward declarations to do the following:
• Define subprograms in logical or
alphabetical order.
• Define mutually recursive
subprograms.(both calling each other).
• Group subprograms in a package
Example of forward Declaration:
CREATE OR REPLACE PACKAGE BODY
forward_pack
IS
PROCEDURE calc_rating(. . .); --
forward declaration
PROCEDURE award_bonus(. . .)
IS -- subprograms defined
BEGIN -- in alphabetical order
calc_rating(. . .);
. . .
END;
PROCEDURE calc_rating(. . .)
IS
BEGIN
. . .
END;
END forward_pack;
56) What are triggers?
---- triggers are similar to procedures,
in that they are the named pl/sql blocks with declarative, executable and
exception-handling sections, how ever a procedure is executed explicitly from
another block via a procedure call, which can also pass arguments.
---- A trigger is executed implicitly
when ever a particular event task places. And is nothing but a event.
---- The triggering event is a
DML (insert, update, delete) operations on a data base table
----- fires whenever a data event(such as DML) or system event(such as
login or shutdown) occurs on a schema or database
Trigger timing : 1) before
2)
after
3)
instead of ( this is used for views)
Triggering events : 1) insert
2)update
3) delete
Trigger type : 1) statement level
2) row
level.
Firing sequence of database triggers
1) before statement
trigger
2) before row trigger
3) after row trigger
4) after statement
trigger
Ex:
1) Create or replace trigger secure_emp
Before
Insert on emp
Begin
If
(to_char(sysdate,’dy’) in(‘sat’,’sun’)) or
To_char(sysdate,’hh24:mi’)
Not between
’08:00’ and ’18:00’)
Then raise_application_error(-20500,’u can insert in the office
timings’)
End if;
End;
Ex :- 2) write a program to all transitions with name
smith?
Create or replace
Trigger
trigger_name
Before insert or
update or delete
On emp
For
each row
When
(old.ename =’smith’ or
New.ename =’smith’)
Begin
Raise_application_error(-20003,’smith’);
End;
57) Difference between triggers
and procedures?
|
Defined with create trigger
|
Defined with create procedure
|
|
The data dictionary contains source code in the user_triggers.
|
Data dictionary contains source code in user_source
|
|
Implicitly invoked
|
Explicitly invoked
|
|
Commit, save point and rollback are not allowed(TCL)
|
Those are allowed
|
58) LOCKS?
-- Is to reduce concurrency
1) share lock
---it allows the other users
for only reading not to insert or update or delete.
2) exclusive lock
--- only one user can have the
privileges of insert or update and delete of particular object
--- others can only read.
3) update lock
----multiple user can read,
update delete
Lock levels :
1) table level 2) table space 3) data base level.
58) What is template?
a) The TEMPLATE form is the required
starting point for all development of new
Forms.
b) The TEMPLATE form includes
platform–independent attachments of several
Libraries.
APPSCORE :- It contains package
and procedures that are required of all forms to support the MENUS ,TOOLBARS.
APPSDAYPK :- It contains packages
that control the oracle applications CALENDER FEATURES.
FNDSQF
:- it contains packages and procedures for MESSAGE DICTONARY, FLEX
FIELDS, PROFILES AND CONCURRENT PROCESSING.
CUSTOM
:- it allows
extension of oracle applications forms with out modification of oracle
application code, you can use the custom library for customization such as zoom ( such as moving to another form and
querying up specific records)
59)
What are ad-hoc reports?
Ans.: Ad-hoc Report is made to meet one-time reporting
needs. Concerned with or formed for a
particular purpose. For example, ad
hoc tax codes or an ad hoc database query
60) What is responsibility?
Is collection of menus,
request security groups and data groups
Menus: collection of forms is nothing but
menus
Request security groups:
collection of programs.
Data groups: is a group
of modules to be made accessible by the user through
Responsibility
System adminàsecurityàdefine
Securityàuseràdefine
61) What are different execution methods of executabls?
FlexRpt The execution file is wrnitten using
the FlexReport API.
FlexSql The execution file is written using
the FlexSql API.
Host The execution file is a host script.
Oracle
Reports The execution file is an Oracle
Reports file.
PL/SQL
Stored Procedure The execution file
is a stored procedure.
SQL*Loader The execution file is a SQL script.
SQL*Plus The execution file is a SQL*Plus
script.
SQL*Report The execution file is a SQL*Report
script.
Spawned The execution file is a C or Pro*C
program.
Immediate The execution
file is a program written to run as a subroutine of the concurrent manager. We
recommend against defining new immediate concurrent programs, and suggest you
use either a PL/SQL Stored Procedure or a Spawned C Program instead.
Composite Datatypes :
– PL/SQL TABLES
– PL/SQL RECORDS
-
Nested TABLE
-
VARRAY
What is
the sequence of functions – group by,having,orderby in a select statements ?
Select…..
Group by…
Having…
Orderby..
Difference
between User and Super User?
User :
login user or front end user
Super user
: it has full access of particular module
