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 something 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.
Conventional: The conventional path loader essentially loads
the data by using standard ‘insert’ statement.
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,”oracleapps4u”,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
to 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 theUTL_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;

validate the data and then dump into the interface tables.
· Through the standard programs we will push the
data from interface tables to Base tables.
11) What are the validations in customer interface?
· customer name : The same customer reference can’t have
different customer
names with in this table

· customer number: must be null if your r using
automatic customer numbering, must exit if you are not using
automatic customer numbering. This value much be unique with in HZ_PARTIES
· customer status : must be ‘A’ for active or ‘I’ for
inactive
HZ_PARTIES_STATUS
· bank account num or bank account currency code :
if the bank a/c already exist do not enter a value
if the bank a/c does not exist you must enter a value
· bank a/c name : it must exist in AP_BANK_ACCOUNTS or if it does not exist
values must exist for BANK_A/C_CURRENCY_CODE
BANK_A/C_NUM
BANK_NAME
BANK_BRANCH_NAME

31) Difference between Bind and Lexical parameters?
BIND VARIABLE:
-- are used to replace a
single value in sql, pl/sql
-- Bind variable may be
used to replace expressions in select, where, group, order
by,
having, connect by, start 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 statement.
Simple Matrix Report: 4 groups
1.
Cross Product Group
2.
Row and Column Group
3.
Cell Group
4.
Cell column is the source of a cross product summary that
Becomes
the cell content.
Frames:
1. Repeating frame for
rows (down direction)
2.
Repeating frame for columns (Across)
3.
Matrix object the intersection of the two repeating frames
Confine mode:
On: child objects
cannot be moved outside their enclosing parent objects.
Off: child objects can be moved outside their enclosing
parent objects.
Flex mode:
On:
parent borders "stretch" when child 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.
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.
37) 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.
38) 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 developer. 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
· Declare: create a named sql area
· Open: identify the active set.
· Fetch: load the current row in to variables.
· Close: release the active set.
CURSOR ATTRIBUTES:
· %is open: evaluates to true if the cursor is open.
· %not found: evaluates to true if the most recent fetch does not return a row
· %found: evaluates to true if the most recent fetch returns a row.
· %row count: evaluates to the total number of rows returned to far.
EXAMPLE:
Begin
Open emp_cursor;
Loop
Fetch when emp_cursor % rowcount >10 or
Emp_curor % not found;
dbms_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;
39) 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;
40) Attribute data types?
1) %type 2)
%row type.
41) Exception Handling?
Is a mechanism provided by pl/sql to detect runtime errors and process them without
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
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 =’Oracleapps4u’
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;
42) Can u define exceptions twice in same block?
No
43) Can you have two functions with the same name in
a pl/sql block?
Yes
44) Can you have two stored functions within the same name?
Yes
45) Can function be overload?
Yes
46) What is the maximum number of statements that can be specified
in a trigger statement?
One
47) Can functions be overloaded?
Yes
48) Can 2 functions have same name & input parameters but differ
only by return data type
No
49) What is a 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.
50) 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;
