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.
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 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;

· customer status : must be ‘A’ for active or ‘I’ for inactive
HZ_PARTI ES_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
Note : every interface table has two error msg

Check the blog post for more details on SRW Package: http://oracleapps4u.blogspot.com/search/label/SRW%20Package
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.
35) 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.
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;
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 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
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 รจ 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 with in 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 PACK AGE 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;
