Oracle app’s technical
document
1) What is ERP? Architecture of apps?
A packaged business software system
that lets a company automate and integrate the majority of its business
processes; share common data and practices across the enterprise; [and]
produce and access information in a real-time environment.
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 = <Directory name>
EX:-
--remember to update INITSID.ORA,
--utl_file_dir = ‘c:\oradata’
Declare
Fp
utl_file.file_type;
Begin
Fp
:= utl_file.fopen(c:\oradata’,tab1.txt’,’w’);
Utl_file.putf(fp,’%s
%s \n ‘text field’, 55);
Utl_file.fclose(fp);
End;

2. How to
send additional customer and address information through customer interface
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 batch 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 )

with cause of queries.
-- bind reference may not be referenced in FROM clause (or) in place of
reserved words or clauses.
LEXICAL REFERENCE:
-- you can use lexical reference to replace the clauses appearing AFTER
select,
from, group by, having,
connect by, start with.
-- you can’t make lexical reference in a pl/sql statmetns.

39) what is Flex mode and Confine
mode?
Confine mode
On: child
objects cannot be moved outside their enclosing parent objects.

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.
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;
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
