1. Introduce yourself

2. Difference between having and group by

HAVING is only for conditions involving aggregates used in conjunction with the GROUP BY clause. eg. COUNT, SUM, AVG, MAX, MIN. WHERE is for any non-aggregage conditions. They can even be used together in the same query

. SELECT t1.id, COUNT (*) FROM table1 AS t1

INNER JOIN table2 AS t2 ON t2.t1_id = t1.id

WHERE t1.score > 50

GROUP BY t1.id HAVING COUNT (*) > 2;

3. What is IN parameter and OUT parameter in PLSQL?

1. IN - The parameter can be referenced by the procedure or function. The value of the parameter can not be overwritten by the procedure or function. 2. OUT - The parameter cannot be referenced by the procedure or function, but the value of the parameter can be overwritten by the procedure or function.

3. IN OUT - The parameter can be referenced by the procedure or function and the value of the parameter can be overwritten by the procedure or function.

4. Difference between Value sets and Lookups

Value sets and Lookups might look similar and confuse some people but there are some basic differences between the two.

Value Sets LookupsValue sets can be attached to parameters of a concurrent program.

Lookups can n’t be attached to parameters of a concurrent program.

Value Sets are almost never maintained by end users, with the exception of GL Flex field codes. Lookups are maintainable by the users.Value sets are usually maintained by System Administrators.

HR Users will maintain "Ethnic Minority" lookups.

Value sets can contain values that are a result of an SQL Statement. Hence it is possible to make Value Set list of values dynamic.

5. How we can eliminate duplicates without using distinct command?

DELETE FROM emp WHERE rowid IN(SELECT eno,ename,sal,max(rowid) FROM emp GROUP BY eno,ename,sal);

6. How to retrieve a second highest salary from a table?

Select Max(Salary) from Emp Where Salary < (Select Max(Salary) from Emp).

7. Difference between case and decode

DECODE is Oracle standard and CASE is ANSI standard

Both CASE and DECODE can be used in WHERE clause.

CASE can be directly used in PL/SQL but DECODE can be used in PL/SQL through SQL statements only.

Case cannot process null while decode can.

8. The two different types of Exceptions in PL/SQL are: ?

User Defined

Pre-Defined

9. Cursor attributes:

There are five cursor attributes:

%isopen

%found

%notfound

%rowcount

%bulk_rowcount

10. What is %TYPE and %ROWTYPE in PL/SQL??

%TYPE provides the data type of a variable or a database column to that variable. %ROWTYPE provides the record type that represents a entire row of a table or view or columns selected in the cursor.

Ex:- DECLARE  l_rec employee%rowtype;  CURSOR c1  IS    SELECT * FROM employee WHERE empno = 100;BEGIN  OPEN c1;  FETCH c1 INTO l_rec;  CLOSE c1;END;

11. List all different types of Data Types in PL/SQL?

Here are the complete lists of Data Types supported by OracleNumber Data Types

BINARY_INTEGER

NUMBER(p,s)

NATURAL

NATURALN

PLS_INTERGER

POSITIVE

POSITIVEN

SIGNTYPE

NUMERIC(p,s)

FLOAT

DEC(p,s)

DECIMAL(p,s)

INTEGER

DOUBLE PRECISION

 12.Types of Report Triggers:-

a) Report Trigger: Order of Execution of Report Trigger is,· Before Parameter form trigger is fired· After Parameter form trigger is fired· Before Report Trigger is fired· Between pages fires for each page except last one· After Report trigger is fired

13.What is difference between a PROCEDURE & a FUNCTION ?

Function is mainly used in the case where it must return a value. Where as a procedure may or may not return a value or may return more than one value using the OUT parameter.

14. What is difference between % ROWTYPE and TYPE RECORD?

Advantages:% ROWTYPE is to be used whenever query returns a entire row of a table or view.

TYPE rec RECORD is to be used whenever query returns columns of different table or views and variables.

Example:TYPE r_emp IS RECORD (eno emp.empno% type,ename emp ename %type);e_rec emp% ROWTYPEcursor c1 is SELECT empno,deptno FROM emp;e_rec c1 %ROWTYPE.

15. Can you have multiple layout templates for a singe data template?

Yes! Multiple layouts can be attached, so that user will have a choice here to use one among them at the time of concurrent program submission

DECODE is a function where CASE is a Expression.

16. What is bursting in XML Publisher?

What are the different ways to show/insert an image on XMLP layout?

There are 4 different ways to insert/show an image in rtf:

Insert an image directly on rtf just by using MS word standard feature

Using OA_MEDIA: storing on server and giving physical path of the image

Using URL of a image hosted on some website

Retrieving the image store in a database as BLOB type

17. Difference between delete and truncate

You cann't rollback in TRUNCATE but in DELETE you can rollback. TRUNCATE removes the record permanently.

In case of TRUNCATE, Trigger doesn't get fired. But in DML commands like DELETE Trigger get fired.

You cann't use conditions(WHERE clause) in TRUNCATE.But in DELETE you can write conditions using WHERE clause

18. How many types of indexes

We have mainly two different indexes.

Implicit index and explicit index.

Explicit indexes are again of many types likesimple index, unique index, Bitmap index, Functional index, Organisational index, cluster index.

19. What is trigger? How many types of Trigger are there?

Trigger is a procedure th gets implicitly executed when an insert/update/delete statement is issued against an associated

table. Triggers can only be defined on tables not no views , however triggers on the base table of a view are fired if an

..0Insert/update/delete statement is issued against a view . there are two types of triggers stament level and Row level trigger

Insert

After /For each row

Trigger is fire /update/Befor/for each statement delete

20. Diff b/w view and materialized view

Materialized view is physical duplicate data in a table view is logical representation of table

21. Can we update the view

Suppose you want update view means that time you need to use insted of trigger with that only possible to update view

22. I have one table i created view and materialized view on a table if i delete a table, Can i see the view and materialized view?

23. Can u call function in same function

Yes

24.Can we use tcl commands in trigger

Nope, you cannot.

25. What is the cursor and ref cursor

Generally ref cursor used for passing cursor parameter and also dynamically building the query.

Normal cursor are static cursors and also we can't able to pass like parameters

26. What is the purpose of Token in Concurrent Program Definition form?

Token is used for transferring values towards report builder. Tokens are usually not case – sensitive.

27. Formula column

We use formula column to calculate some information dynamically using information based on the columns of the data model or from the concurrent program parameters. It is basically used to apply some custom logic on input data and return some value.

Formula columns can be written using PL/SQL syntax and we can use pl/sql functions for computation on the data. Formula column will accept data of Character, Number, or Date type.

Ex:- CF_

28. Summary column :-

Summary columns are used for calculating summary information like sum, average etc,. on specific columns of a data group. This column uses a set of predefined oracle aggregate

functions. Summary columns are generally preceded by CS_ to distinguish them from other columns.

The SQLCODE function returns the error number associated with the most recently raised error exception. This function should only be used within the Exception Handling section of your code.

The SQLERRM function returns the error message associated with the most recently raised error exception. This function should only be used within the Exception Handling section of your code.

IBM PLSQL Interview Question

Can we use where condition with truncate?

No, TRUNCATE is all or nothing. You can do a DELETE FROM <table> WHERE <conditions> but this loses the speed advantages of TRUNCATE.

Can you explain the truncate and delete with trigger?

DELETEDelete is the command that only remove the data from the table. It is DML statement. Deleted data can be rollback. By using this we can delete whole data from the table(if use without where clause). If you want to remove only selected data then we should specify condition in the where clausedelete from employee ;( this command will remove all the data from table)delete from employee where employee name='JOHN';(This command will remove only that row from employee table where employee_name is JOHN');

DROP:Drop command remove the table from data dictionary. This is the DDL statement. We can not recover the table before Oracle 10g. But Oracle 10g provide the command to recover it by using the command (FLASHBACK)

TRUNCATE:This is the DML command. This command delete the data from table. But there is one difference from ordinary delete command. Truncate command drop the storage held by this table. Drop storage can be used by this table again or some other table. This is the faster command because it directly drop the storage

4>In case of TRUNCATE, Trigger doesn't get fired. But in DML commands like DELETE .Trigger get fired.

5>you cann't use conditions (WHERE clause) in TRUNCATE. But in DELETE you can write conditions using WHERE clause

Can we use truncate and delete command to disable the referential integrity constraint?

> First time asker, long time reader! My question:

I wish to delete all records from a parent table and all records from a child table.

If I delete from from the child table then delete from the parent,

Everything works fine. But if I truncate the child table, then try to

truncate the parent, I get an error:

> ERROR at line 1:

> ORA-02266: unique/primary keys in table referenced by enabled foreign keys

> Do you have insight into this?

Differences between the DELETE command and the TRUNCATE command.

DELETE removes one or more records in a table, checking referential

Constraints (to see if there are dependent child records) and firing any

DELETE triggers. In the order you are deleting (child first then parent)

There will be no problems.

TRUNCATE removes ALL records in a table. It does not execute any triggers.

Also, it only checks for the existence (and status) of another foreign key

Pointing to the table. If one exists and is enabled, then you will get

Your error. This is true even if you do the child tables first.

You should disable the foreign key constraints in the child tables before

Issuing the TRUNCATE command, then re-enable them afterwards.

How did you export the data from database to excel file?

How many types of functions in UTL_FILE package?

With the Oracle-supplied UTL_FILE package, you can read from and write to operating system files. It Provides security for directories on the through the init. Ora file. UTL_FILE Procedures and Functions:• Function FOPEN• Function IS_OPEN• Procedure GET_LINE• Procedure PUT, PUT_LINE, PUTF• Procedure NEW_LINE• Procedure FFLUSH• Procedure FCLOSE, FCLOSE_ALL

What function you are using to load the data in UTL_FILE package?

Introduced in Oracle 7.3, UTL_FILE PL/SQL package provides a functionality of reading and writing text file into operating system files. That means you can load external data from other source to database or can generate report from your PL/SQL code and write to text file on operating system.

UTL_FILE package provides access to text file on the OS of the database server. You can use

one of the following approaches to restrict access to text file from database server.

Use the UTL_FILE_DIR parameter in init.ora initialization file to specify the accessible directory for the UTL_FILE functions to read or write operation

UTL_FILE_DIR ='E:\app\madhurendra\wr_file' Use the CREATE DIRECTORY statement [ORACLE 9i or above]to associate an

operating system directory with alias to provide read/write operation CREATE DIRECTORY my_demo_dir AS 'E:\app\madhurendra\wr_file'; GRANT READ, WRITE ON DIRECTORY my_demo_dir TO user$plsql;

Followings are some procedures, functions and exceptions of the UTL_FILE package.DATA TYPEFILE_TYPE Data type for a file-handlePROCEDURES & FUCTIONSIS_OPEN Checks whether file is open or not. Returns TRUE if open and FALSE if close.FOPEN Opens a file for read or write.FCLOSE Closes an open fileFCLOSE_ALL Closes all open file for the current sessionNEW_LINE Insert a new line terminator to a filePUT_LINE Write strings of text followed by a new line terminatorPUT Same as PUT_LINE but don’t place a new line terminator.PUTF Writes formatted text into fileGET_LINE Read a line from file. The maximum outputFFLUSH Writes all the buffered data into fileEXCEPTIONSINVALID_PATH File location is not valid

INVALID_MODE OPEN_FILE mode is not valid. [Specific to FOPEN]INVALID_FILENAME Filename is not validREAD_ERROR Operating system error occurred during the read operation.WRITE_ERROR Operating system error occurred during the write operation.FILE_OPEN Operation failed because the file is already open.These exceptions must be prefixed with UTL_FILE. Apart from that UTL_FILE can also raise pre-defined exceptions like NO_DATA_FOUND and VALUE_ERROR.Followings are a couple of very simple example of UTL_FILE package:In the following anonymous block, data is written by UTL_FILE package to a text file ‘my_f_file.txt’.

DECLARE v_file UTL_FILE.FILE_TYPE;BEGIN v_file := UTL_FILE.FOPEN('MY_DEMO_DIR', 'my_f_file.txt', 'w'); UTL_FILE.PUT_LINE(v_file, 'Hello World!'); UTL_FILE.PUT_LINE(v_file, 'I stared using UTL_FILE'); UTL_FILE.FCLOSE(v_file);END;

How many types of trigger?

BEFORE UPDATE, Statement Level BEFORE UPDATE, Row Level AFTER UPDATE, Statement LevelAFTER UPDATE, Row Level

How many max triggers you will declare what is instead of trigger?

You can create N numbers of triggers on a table but the maximum possible types trigger can be applied is 3*2*2=12

(Insert/Update/Delete= 3, before/after= 2, Row Level/Statement Level=2)

What is implicit and explicit cursor?

PL/SQL declares a cursor implicitly for all SQL data manipulation statements, including quries that return only one row. However, queries that return more than one row you must declare an explicit cursor or use a cursor FOR loop.Explicit cursor is a cursor in which the cursor name is explicitly assigned to a SELECT statement via the CURSOR...IS statement. An implicit cursor is used for all SQL statements Declare, Open, Fetch, Close. An explicit cursors are used to process multi row SELECT statements An implicit cursor is used to process INSERT, UPDATE, DELETE and single row SELECT. .INTO statements.

What is exception?

PL/SQL provides a feature to handle the Exceptions which occur in a PL/SQL Block known as exception Handling. Using Exception Handling we can test the code and avoid it from exiting abruptly.When an exception occurs messages which explains its cause is received. PL/SQL Exception message consists of three parts. 1) Type of Exception2) An Error Code3) A message

How many types of exception Can we have more than one exception?

Types of Exception.There are 3 types of Exceptions. a) Named System Exceptions b) Unnamed System Exceptions c) User-defined Exceptions

DECLARE --<Declaration section >BEGIN --<logic>EXCEPTION WHEN ex_name1 THEN -Error handling statements WHEN ex_name2 THEN -Error handling statements WHEN Others THEN -Error handling statements END;

What are predefined exceptions?

PL/SQL provides many pre-defined exceptions, which are executed when any database rule is violated by a program. For example, the predefined exception NO_DATA_FOUND is raised when a SELECT INTO statement returns no rows. The following table lists few of the important pre-defined exceptions:

Exception Oracle Error

SQLCODE Description

ACCESS_INTO_NULL 06530 -6530 It is raised when a null object is automatically assigned a value.

CASE_NOT_FOUND 06592 -6592 It is raised when none of the choices in the WHEN clauses of a CASE statement is selected, and there is no ELSE clause.

COLLECTION_IS_NULL 06531 -6531 It is raised when a program attempts to apply collection methods other than EXISTS to an uninitialized nested table or varray, or the program attempts to assign values to the elements of an uninitialized nested table or varray.

DUP_VAL_ON_INDEX 00001 -1 It is raised when duplicate values are attempted to be stored in a column with unique index.

INVALID_CURSOR 01001 -1001 It is raised when attempts are made to make a cursor operation that is not allowed, such as closing an unopened cursor.

INVALID_NUMBER 01722 -1722 It is raised when the conversion of a character string into a number fails because the string does not represent a valid number.

LOGIN_DENIED 01017 -1017 It is raised when s program attempts to log on to the database with an invalid username or password.

NO_DATA_FOUND 01403 +100 It is raised when a SELECT INTO statement returns no rows.

NOT_LOGGED_ON 01012 -1012 It is raised when a database call is issued without being connected to the database.

TOO_MANY_ROWS 01422 -1422 It is raised when s SELECT INTO statement returns more than one row.

VALUE_ERROR 06502 -6502 It is raised when an arithmetic, conversion, truncation, or size-constraint error occurs.

ZERO_DIVIDE 01476 1476 It is raised when an attempt is made to divide a number by zero.

Do you know TOO_MANY ROWS, when that exception will occur and NO_DATA FOUND How to catch any type of exception?

DECLARE v_drop_partition VARCHAR2(1) := NULL;BEGIN SELECT drop_partition INTO v_drop_partition FROM xxx.part_maint WHERE drop_partition = 'Y' ; FOR prec IN (SELECT * FROM xxx.part_maint WHERE drop_partition = 'Y' ) LOOP DBMS_OUTPUT.PUT_LINE (prec.SCHEMA_NAME || ' ' || prec.OBJECT_NAME); END LOOP;EXCEPTION WHEN NO_DATA_FOUND THEN DBMS_OUTPUT.PUT_LINE ('hello');END;

Can we commit in trigger?

Yes, You can Commit inside the trigger.But for this you have to make this trigger transaction to be a Independent transaction from its parent transaction, You can do this by using Pragma. Pragma AUTONOMOUS_TRANSACTION allow you to build the Independent(child) Transaction, started by another. Shold be declare in DECLARE section of any subprogram.Used to make Modular and Reusable Blocks. if you need the example then ask to me.

CREATE OR REPLACE TRIGGER triggerAFTER INSERT ON t1 FOR EACH ROW

DECLARE PRAGMA AUTONOMOUS_TRANSACTION; i PLS_INTEGER; BEGIN SELECT COUNT(*) INTO i FROM t1;

INSERT INTO t2 VALUES (i); COMMIT;END;

What is autonomous transaction?

An autonomous transaction is an independent transaction to the main or parent transaction. If an Autonomous transaction is started by another transaction it is not nested, but independent of parent transaction.

CREATE OR REPLACE PROCEDURE child block IS

BEGIN INSERT INTO t

(test value) VALUES ('Child block insert'); COMMIT; END child_block;

What is view?

An Oracle VIEW, in essence, is a virtual table that does not physically exist. Rather, it is created by a query joining one or more tables.

CREATE VIEW view name AS

SELECT columns

FROM tables

[WHERE conditions];

Can we delete a record in view?

Can we delete a record more than one table?

DELETE FROM usession

WHERE session_id = (SELECT session_id

FROM usession

WHERE delete_session_id IS NULL

AND user_id = (SELECT user_id

FROM users

WHERE REGEXP_LIKE(USER_NAME,

'awpeople', 'i')));

Can we write trigger on view?

Create trigger tri_account

Before insert or update

on account

for each row

Begin

IF (:new.acct_id = 2 and :new.cust_id = 23) THEN

raise_application_error( -20001, 'No insertion with id 2 and 23.');

END IF;

end;

Do you have use any debugging tool?

Do you know global variable, difference between global variable and parameter variable?

Well, basically, a global variable is a variable that can be used anywhere. But local variable is

a variable that can be used in with in sub programs.

Do you know about cascading triggers?

When a statement in a trigger body causes another trigger to be fired, the triggers are said to be cascading. Max = 32. 

a) Commiting : A transaction is said to be commited when the transaction makes permanent changes resulting from the SQL statements.

b) Rollback : A transaction that retracts any of the changes resulting from SQL statements in Transaction.

c) SavePoint : For long transactions that contain many SQL statements, intermediate markers or savepoints are declared. Savepoints can be used to divide a transactino into smaller points. d) Rolling Forward :: Process of applying redo log during recovery is called rolling forward.

What are Database Triggers and Stored Procedures?

Database Triggers:-Database Triggers are Procedures that are automatically executed as a result of insert in, update to, or delete from table. Database triggers have the values old and new to denote the old value in the table before it is deleted and the new indicated the new value that will be used. DT are useful for implementing complex business rules which cannot be enforced using the integrity rules. We can have the trigger as before trigger or After

Trigger and at Statement or Row level. e.g.:: operations insert, update ,delete 3 before ,after 3*2 A total of 6 combinations At statement level(once for the trigger) or row level( for every execution ) 6 * 2 A total of 12. Thus a total of 12 combinations are there and the restriction of usage of 12 triggers has been lifted from Oracle 7.3 Onwards. Stored Procedures:: Stored Procedures are Procedures that are stored in Compiled form in the database. The advantage of using the stored procedures is that many users can use the same procedure in compiled and ready to use format.

What is Profile? Explain different levels of Profile?

A user profile is a set of changeable options that affects the way your applications run. Oracle Application Object Library establishes a value for each option in a user‟s profile when the user logs on or changes responsibility. Your user can change the value of profile options at any time a) To create Profile Option. ( Profile Option can created by developer in application developer area) b)set the value (Values of the profile option , who will have what value at various levels is set by SYSADMIN). Oracle Application Object Library provides many options that. (Edit profile feature for every user is available to set any value to allow the user).your users can set to alter the user interface of your applications to satisfy their individual preferences. Profile Option – set at run time like – User Related, responsibility, Sequence, Printer, Security.

Values in 4 Levels(HIEARCHY WISE) :- USER RESPONSIBILITY APPLICATION SITE Application Developer create the profile. System Administrator make profile option. (NOTE:- If any change in value, it will active when you re-login or switch to the responsibility.) ( Usage in the multi-tier, the profile is biggest impact)

Difference between View vs Materialized View in database?

Based upon on our understanding of View and Materialized View, Let’s see, some short difference between them :

1) First difference between View and materialized view is that, In Views query result is not stored in the disk or database but Materialized view allow to store query result in disk or table.

2) Another difference between View vs materialized view is that, when we create view using any table, rowid of view is same as original table but in case of Materialized view rowid is different.

3) One more difference between View and materialized view in database is that, In case of View we always get latest data but in case of Materialized view we need to refresh the view for getting latest data.

4) Performance of View is less than Materialized view.

5) This is continuation of first difference between View and Materialized View, In case of view its only the logical view of table no separate copy of table but in case of Materialized view we get physically separate copy of table

6) Last difference between View vs Materialized View is that, In case of Materialized view we need extra trigger or some automatic method so that we can keep MV refreshed, this is not required for views in database.

What is the Diff between APPS Schema and other Schemas?

Apps schema contains only Synonyms we can't create tables in apps schema, where as other schemas

contains tables, & all the objects. Here only we will create the tables and giving grants on created tables.

Almost all every time we will connect to apps schema only.

What is meant by Custom Top and what is the Purpose?

Custom Top is nothing but Customer Top, which is created for customer only. we can have multiple customtops based on client requirement. It is used to store developed & customized components.

Whenever oracle corporations applying patches it will over ride on all the modules except custom top.

That’s why we will use custom top.
