Oracle Database 10g:SQL Fundamentals II 2-12

In Oracle Database 10g:SQL Fundamentals II Edition 1.1 Dated August 2004. On the page 2-12.
The last parenthesis is closed but not opened.

Is this book part of the Oracle product, or a third-party book (including Oracle Press)? If it's third-party, the publisher would appreciate knowing the problem, but you'd have to write to them. The Oracle staff monitoring documentation questions on this forum don't have anything to do with the third-party books.
Thanks,

Questions About Chapter 2 in Oracle DB 10g: SQL Fundamentals II

Hello,
first of all i'm glad to be a member of your forum. I have joined a beginner Oracle Course: Intro to SQL. I'm facing some problems understanding some concepts in Chapter 2 of Oracle Database 10g: SQL Fundamentals II text book. I got about 15 questions. However, i will only ask two questions at first. Since i'm a newbie, please answer it in a simplistic form. Excuse me if you see grammatical mistakes.
Dropping a column can take a while if the column has a large number of values. In this case it may be better to set it to be unused and drop it when the number of users on the system are fewer to avoid extended locks.
Questions:
"when the number of users on the system are fewer to avoid extended locks."
1. Can you explain this to me please?! fewer than before? fewer than? What if users kept increasing during the years! then this "fewer" may not happen until the company collapse!
2. Why do we need to use unused columns? When should we use unused columns?

Great! .... I got more questions, i just do not want to open a new same thread. Thus, i will just post the questions in here and i hope i will get help from experts...Please bare with me guys...The questions are numbered, unnumbered parts are information that helps you understand my question.
Note: just answer what you are willing to, one question or whatever you want. I'm not expecting to get all the answers from one member :)
Thanks for understanding
Page 2-7:
Certain columns can never be dropped such as columns that form part of the partitioning
key for a partitioned table or columns that form part of the primary key of an index- organized table.
Questions:
"columns that form part of the partitioning key for a partitioned table"
*1. Do they mean one table can be split into two different storage? What is the thing that*
link these both tables to make Oracle Server realize these two tables are actually one table? Is is tablespace_name?
"columns that form part of the primary key of an index-organized table."
*2. Can you clarify the above sentence please*
*3. If i have set of columns that has large amount of data, i rather set them unused then*
drop them because the response time is going to be faster! I do not get it, can you
explain please? What i know is drop drops the column and release the disk space whilst
unused column make the columns useless and does not release disk space yet until we drop them, so
drop column does it in one step unlike taking the unused column process. In brief, i would like to know
why dropping unused columns that has large set of data is faster then dropping the column
directly...

4. ALTER TABLE emp2 ADD CONSTRAINT emp_dt_fk
FOREIGN KEY (Department_id)
REFERENCES departments ON DELETE CASCADE);
The above query is written in text book. I think it should be written as
ALTER TABLE emp2 ADD CONSTRAINT emp_dt_fk
FOREIGN KEY (Department_id)
REFERENCES departments(dept_id) ON DELETE CASCADE;
Am i correct?
*5. Can you tell me what deferring constraints is in one sentence please? Why do we need it? When do we need it in real-life?*
*7. You can defer checking constraints for validity until the end of the transaction. A*
constraint is deferred if the system checks that it is satisfied only on commit. If a
deferred constraint is violated, then commit causes the transaction to roll back.
I do not understand the above paragraph, please explain. What i know is "end of
transaction" ends with ; or commit
Page 2-18
create table test1 (
pk NUMBER PRIMARY KEY,
fk NUMBER,
col1 NUMBER,
col2 NUMBER,
CONSTRAINT fk_constraint FOREIGN KEY (fk) REFERENCES test1,
CONSTRAINT ck1 CHECK (pk > 0 and col1 > 0),
CONSTRAINT ck2 CHECK (col2 > 0) );
-- "CONSTRAINT fk_constraint FOREIGN KEY (fk) REFERENCES test1"
*8. This is wrong isn't it? It references to test1 but no column specified.*
An error is returned for the following statements:
ALTER TABLE test1 DROP (pk); -- pk is a parent key.
*9. We can not drop it because we did not mention ON DELETE CASCADE. Am i right?*
ALTER TABLE test1 DROP (col1) -- col1 is referenced by multicolumn constraint ck1.
*10. I do not get it, can you explain please. col1 is not referenced, i see CHECK constraint is applied*
but no references made. Secondly, is ck1 considered multicolumn because it check two columns?
Or multicolumn here represents something else?
ALTER TABLE emp2
DROP COLUMN employee_id CASCADE CONSTRAINTS;
*11. This drop employee_id column and all its child. Correct?*
ALTER TABLE test1
DROP (pk, fk, col1) CASCADE CONSTRAINTS;
*12. This drops three columns and all its child if there are any. Correct?*
*13. Then what's the difference between ON DELETE CASCADE and CASCADE CONSTRAINTS?*
For example, What if employee_id in emp2 table definition does not have ON DELETE CASCADE,
will CASCADE CONSTRAINTS work? Please explain...
Page 2-22
When you are expecting a large data load and want to speed the operation. You may want
to disable the constraints while performing the load and then enable them, in which case
having a unique index on the primary key will still cause the data to be verified during
the load. So you can first create a nonunique index on the column designated as PRIMARY
KEY, and then create the PRIMARY KEY column and specify that it should use the existing
index.
Example:
1. create the table
create table new_emp
(employee_id number(6),
first_name varchar2(10)
2. create the index
create index emp_id_idx2 on new_emp(employee_id);
"You may want to disable the constraints while performing the load and then enable them"
so i suggest to load all data i want into new_emp.
3. create the primary key
alter table new_emp ADD primary key (employee_id) USING index emp_id_idx2;
What i understand is the following:
If we want to load large data into the new_emp, its better to create the table without any
constraints - in our case the constraint is primary key. After that, we create nonunique
index points to employee_id and then load data into new_emp. Finally, specify employee_id
as primary key using the nonunique index.
*14. Is my explanation correct?*
"in which case having a unique index on the primary key will still cause the data to be
verified during the load."
*15. Data to be verified against what? Is it to be verified whether its NULL or NOT NULL? I*
know primary key does not take NULL and every value must be unique.
After loading all data we want, what if i did
"alter table new_emp ADD primary key (employee_id);"
*16. Will i face any problems or inefficient process?*
I do not think we need step two, we could do the following:
1. create the table
create table new_emp
(employee_id number(6),
first_name varchar2(10)
"You may want to disable the constraints while performing the load and then enable them"
so i suggest to load all data i want itno new_emp.
2. create the primary key
alter table new_emp ADD primary key (employee_id);
*17. The above steps are as efficient as the three steps i mentioned above. The only difference*
is we let index be created implicitly. Right? If no, why?
Page 2-23
CREATE INDEX upper_dept_name_idx ON dept2(UPPER(department_name));
The following statement may use the index, but without the WHERE clause the
Oracle server may perform a full table scan:
select *
from employees
where UPPER(last_name) IS NOT NULL
ORDER BY UPPER (last_name);
"but without the WHERE clause the Oracle server may perform a full table scan"
*18. The above query let oracle server perform full table scan anyway! Right? It has to go*
through every field and check is it not null or not. I know we are using function-based
index but there are alot of not null last_name! so oracle server must scan one by one. If
we only had one not null field, then i would say Oracle server can point to that field
immediately by the aid of function-based index we created above. Can you clarify please...
Another related topic statement that i do not get it yet:
"The oracle server treats indexes with columns marked DESC as function-based indexes."
*19. The bove statements is so general. What if we have a column ordered by DESC order and we*
did not create any function-based indexes, will statement be true?!
Lets go back the above query:
ORDER BY UPPER (last_name);
*20. Its not DESC. To me, the above query does not flow with this statement "The oracle server treats*
*indexes with columns marked DESC as function-based indexes."?*
Page 2-27
Regarding FLASHBACK TABLE, you can invoke a flashback table operation on one or more
tables, even on tables in different schema. You specify the point in time to which you
want to revert by providing a valid timestamp. By default, database triggers are disabled
for all tables involved. You can override this default behavior by specifying the ENABLE
TRIGGERS clause.
"By default, database triggers are disabled for all tables involved. You can override this
default behavior by specifying the ENABLE TRIGGERS clause."
*21. What are database triggers?*
*22. About External Tables. What are external tables? When is it used in real-life? Why do*
we want External Tables?
Page 2-30
Oracle server provides two major access drivers for external tables. They are
ORACLE_LOADER access driver and ORACLE_DATAPUMP access driver. ORACLE_DATAPUMP used to
both import and export data using a platform-independent format.
"platform-independent format."
*23. What is the format? Is it .dat?*

Oracle Database 11g: SQL Fundamentals I 1Z0-051 Question

i bought the OCA Oracle Database 11g: SQL Fundamentals I Exam Guide (Exam 1Z0-051) and i am not sure do i have to read the whole book ! or just go through the exam objectives table ? because the book covers lots of topics that's not in the exam and i am kind of tight on time if any one had the book or used it pls help
To make it more clear i have a table in the book that shows each exam topic with page number next to it Like this:
Restricting and Sorting Data
[ ]      Limit the rows that are retrieved by a query Pg:104
[ ]      Sort the rows that are retrieved by a query Pg:136
[ ]      Use ampersand substitution to restrict and sort output at runtime
Using Single-Row Functions to Customize Output
[ ]      Describe various types of functions available in SQL Pg:170
[ ]      Use character, number, and date functions in SELECT statements Pg:177
Edited by: user7804566 on 01-Mar-2009 02:00

Yes indeed. Practice at work (and elsewhere) is the best way to learn and ro reinforce learning.
However, the more you read, the more you will be exposed to ideas and variations. Eventually you will find that many of the books have errors in various places. You will be winning when you are able to read and identify the errors AND explain why they are errors.
The way your original question was written implied that you were after the minimum effort to pass an exam. Your last reply implies a different, and better, attitude.
My suggestion therefore is to concentrate on the actual examples, but as quickly as possible expand to areas of interest. Explore as much as you possibly can, but make it a 'learning exploration' byut asking yourself questions and then investigating what the answer is.
Also note that in Oracle nearly every answer has an exception. The best of the best know this and try very hard to understand when things go according to plan and when (and why) expections occur.

Do i have to pay exam center fee to an authorized oracle exam center(new horizon) in Bangladesh rather than the exam fee of Oracle Database 11g: SQL Fundamentals I ?

Do i have to pay exam center fee to an authorized oracle exam center(new horizon) in Bangladesh rather than the exam fee of Oracle Database 11g: SQL Fundamentals I ?

I agree with Matthew that I cannot be sure exactly what you are asking.
Generally i regard it as less risk to yourself to schedule and pay Pearson Vue directly.
However if you contact the exam center and get them to schedule for you my understanding is you pay them. Unfortunately there is risk of the exam center overcharging you (99%++ of most most worldwide wont).
The only reasons for doing this I can think of is (there may be more) :-
- is if you do not have credit/debit cards that Pearson Vue would accept.
- The center will accept turn up and schedule and your transport to the exam center might be unreliable and you are worried you might miss the appointment and you are hoping to pay on arrival (some will not accept this).

How to 100% Protect PL/SQL Code By Wrapped in Oracle Database 10g R2

Hello,
Is Possible to 100% Protect PL/SQL Code By Wrapped in Oracle 10g R2 ?
If it is not possible by wrap in oracle 10g R2,
Please, let me suggest, how i will be able to 100% protect PL/SQL code in Oracle Database 10g R2.
Because, I have lot of functions, procedures & package's in my project.
Which is running in field filed.
So, i have needed to protect 100%.
Also, will i convert to al functions, procedures & package's to .pll file ?
And .pll file to .plx file?
Is it possible to convert .plx file to .pll file ?
Please, let know any better solutions in this case....
Regards
Mehedi

Hello,
No, wrapping is not a 100% secure method. It could prevent your code from amateurs, but not from professional hackers. Look at the article http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/wrap.htm#BEHGBJAA
It says: "•Wrapping is not a secure method for hiding passwords or table names.
Wrapping a PL/SQL unit prevents most users from examining the source code, but might not stop all of them."

Creating a new database in Oracle Database 10g...

I have downloaded a copy of Oracle Database 10g Express Edition from Oracle's website. I am using Windows XP. I am trying to create an Oracle database that I can connect to from Access 2003 via ODBC.
1. How do I create a new database? I can see options to create tables, views, etc. but not a database.
2. I have created a System DSN connection in the ODBC Data Source Administrator for the Oracle ODBC driver. Once I create a database in Oracle, how do I actually establish a connection to it from Access? The ODBC code to connect is there, but when I run it, I get an error.
Any help would be appreciated. Thanks.

1. How do I create a new database? I can see options to create tables, views, etc. but not a database.If you can see those options then you are already connected to the database. You probably want to create a user, not a database (are you by chance coming from SQL Server?)
driver={OracleDriver};Dbq=TESTDBQ;Uid=Administrator;Pwd=;You would replace "Administrator" with the name of the user you created in the database.

Problem upgrading Apex 2.1 to 3.2.1 in Oracle Database 10g Express Edition

G'Day Apex gurus,
I installed Oracle Database 10g Express edition in my Windows XP PC which comes with Apex 2.1 with no problems. Then I wanted to upgrade Apex 2.1 to 3.2.1 (Currently Apex download in OTN) following the document below:
http://www.oracle.com/technology/products/database/application_express/html/3.1_and_xe.html
I went to the steps:
@apexins SYSAUX SYSAUX TEMP /i/
Then to change the password for the admin account run apxchpwd.sql and when prompted enter a password for the ADMIN account.
@apxchpwd
with not problems
Then I connected to SQL*Plus as SYS by:
sqlplus /nolog
CONNECT SYS as SYSDBA
Enter password: xxxxxxxxxxx
but when I tried to run:
@APEX_HOME/apex/apxldimg.sql APEX_HOME
where APEX_HOME is Apex3.2.1 in my case
SQL> @Apex3.2.1/apex/apxldimg.sql Apex3.2.1 (I get the messages below)
PL/SQL procedure successfully completed.

Can anyone help me in how to trouble shout this?
I tried to continue by following the steps document
@APEX_HOME/apex/apxxepwd.sql password
(where password is the password of the Application Express internal ADMIN account)
but when I tried to login in:
http://localhost:8080/apex/f?p=4550:1
when I type the credentials
system
system
systempassword
nothing happens
or even If I try:
http://localhost:8080/apex/f?p=4550:10
admin
adminpassword
nothing happens here too.
I appreciate any help
Kind regards

My database version is 10.2.0.1.0 Oracle express.
Operating system is Windows Vista.
I started installing using the following commands.
@ C:\temp\apex\apexins.sql
it prompts me for the values of sysaux sysaux temp and c:\temp\apex\images\
If I supply the value for images the sqlplus window closes after scrolling a lot of info.
Enroute it also prompts me for a value for 9:
I don't know what the input shall be.
Then it again stops at enter value for version:
I used 3.2.1.0
The window scrols a while and closes.
later I changed the password and ran the command.
@c:\temp\apex\apxldimg.sql c:\temp
but no success with installation.
the output is as following.

Oracle jpublisher bug or bug in Oracle database 10g ?

Hello,
i`m trying to call web service from pl/sql in oracle database 10g v10.1.0.2.0.
I`ve used this tutorial:
http://www.oracle.com/technology/sample_code/tech/java/jsp/callout_users_guide.htm
used oracle as 10.1.3 web service callout pack for 10g v10.1
and jpublisher 10.2, which has generated pl/sql wrapper package and proxy classes.
I`ve imported with loadjava dbwsclientws.jar and dbwsclientdb101.jar into my user called wscallout.
Also imported proxy classes.
When i`ve tried to call pl/sql function, i`ve got this error:
java.lang.VerifyError: (class: oracle/j2ee/ws/saaj/soap/SOAPDoc, method: getDocumentBuilder signature: ()Loracle/xml/parser/v2/DocumentBuilder;) Wrong return type in function

I haven`t found anything about this issue in oracle metalink, regarding to ORA-29532.

dude if you are using jdeveloper 10.1.3.x for development of web service the library you have loadded into database dwwsclinet etc or sopa.jar or mail .jar will not work
for getting the output for the web services developed on jdeveloper you need following file to upload on database
wsclient_extended for 10.1.3.x.0 where x stands for your version
wsclient_extended.jar which can be downloaded from
http://download.oracle.com/otn/java/oc4j/1013x0/wsclient_extended_1013x0.zip the stands for subversion
xstands for your version
after downloading above file upload it
open up the socket by command
on SYS schema
SQL>call dms_java.grant_permission('YOUR_SCHEMA','SYS:java.net.SocketPermission','<IPaddress ofcomputer>:<portnumber>(eg 10.8.11.98:8888)','connect,resolve');
SQL>call dms_java.grant_permission('YOUR-SCHEMA','SYS:java.util.PropertyPermission','*','read,write');
SQL>call dms_java.grant_permission('YOUR-SCHEMA','SYS:java.lang.RuntimePermission','createClassLoader','');
SQL>call dms_java.grant_permission('YOUR-SCHEMA','SYS:java.lang.RuntimePermission','getClassLoader','');
SQL>call dms_java.grant_permission('YOUR-SCHEMA','SYS:java.lang.RuntimePermission','setContextClassLoader','');
SQL>call dms_java.grant_permission('YOUR-SCHEMA','SYS:java.lang.RuntimePermission','setFactory','');
SQL>call dms_java.grant_permission('YOUR-SCHEMA','SYS:java.lang.RuntimePermission','setIO','');
SQL>call dms_java.grant_permission('YOUR-SCHEMA','SYS:java.lang.RuntimePermission','shutdownHooks','');
SQL>call dms_java.grant_permission('YOUR-SCHEMA','SYS:java.lang.RuntimePermission','accessClassInPackage.sun.util.calender','');
Now make a jar file which contain all your class files of proxy put that jar file on database an compile that jar file on database it should work than convert it into java stored procedure and invoke that procedure
