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.
1) conventional
--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 by ‘”’
(empno,
empname,sal,deptno)
>sqlldr scott/tiger@vis
control=loader.ctl log= gvlog.log bad=gvbad.bad
discard=gvdis.dsc .
3) how do u dump data from pl/sql block to flat
files?
Using utl_file
package, we can dump data from pl/sql block to flat file.
PRE-REQUIREMENTS for UTL_FILE is specify the
accessible directories for the UTL_FILE function in the initialization file
(INIT.ORA) Using the UTL_FILE_DIR parameters.
Ex:
UTL_FILE_DIR =
EX:-
--remember to
update INITSID.ORA,

2. How to send
additional customer and address information through customer
interafce
Here is where attribute columns
are used.
* Additional Customer data can be
populated in
RA_CUSTOMERS_INTERFACE_ALL.customer_attribute1
to 15
This will go into
RA_CUSTOMERS.attribute1 to 15
* 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 Note: 1070800.6 )

GSA_INDICATOR
FOB_POINT
SALES_CHANNEL_CODE
FREIGHT_TERM
WAREHOUSE_ID
PRICE
LIST
SHIP_PARTIAL

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.
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
