SQL Fundamentals I : oe_main.sql , hr_main.sql, ...

Hi forum,
I just bought "SQL Fundamentals I" from McGraw Hill. This book mentions several schemas and creation scripts like hr_main.sql,
oe_main.sql, ... ! Unfortunately I cannot find these scripts for download and it is not on the accompanying CD. In the meantime
I sestablished a 10G Express Database on my notebook for training purposes. The hr schema and the tables in question could
be found there. Does anyone know where to find the scripts necessary for studying this book ?
Kind regards

oeggert2706HR and OE etc. are standard schemas that come as part of the Database installation. Not sure about the express edition, but as Oracle provide them as example schemas, I don't see why they wouldn't be included with that version.

Can't find oe_main.sql and HR_main.sql

I have download and installed latest oracle database successfully (version 11g). When I followed instruction to install sample schema, I couldn't find hr.main.sql and oe_main.sql.
I only found hr_code.sql in demo/schema/human_resources directory.
There are a few sql files under order_entry directory like oe_views.sql. But I can't find oe_main.sql.
I have been struggle with it for a few days. I couldn't find the script file on Internet either. Please help me identify this problem. Thank you very much.

It's been some time ago but I encounter terrible problems with companion cd now. I have downloaded the zip file with examples already couple times and always there are crc errors in the archive that corrupt the instalation. I hate it... but I need the examples...
What should I do?
Download Companion CD from Oracle 10g. This is gonna take another 2 hours with my connection, but let me see...

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

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.

1z0-051: SQL Fundamentals objective inquiry

Hi,
first of all I wish if this is the right way/ forum to ask. If not, please accept my apologies, in advance.
I'm preparing for 1z0-051 Oracle Database 11g SQL Fundamentals 1 exam. My main refrence is :
OCA Oracle Database 11g SQL Fundamentals I Exam Guide (Exam 1Z0-051) Complete Exam Preparation-John Watson and Roopesh Ramklass , from Oracle Press.
I could find in the book a reference for the objective of the Using DDL Statements to Create and Manage Tables:
Describe how schema objects work.
Any help with that objective, please???
Thank you

Hell AHS, I just answered your question in the other topic you opened. The info provided in the link Markus Waldorf gave you is too detailed. You don't need to know about CLUSTER, DIMENSION, EXTERNAL PROCEDURES, etc etc.
I passed the exam not so long ago and the book is enough (along with 5 years using Oracle almost everyday in my case).
Cheers,

I just took the 1Z0-051 SQL Fundamentals test

I read this book to study for the test. I went through the quizes in the book and the cd with test on it that came with the book. I did ok with those. I came across UCertify and saw they had some practice test and everything so i go that too and really used that as my main study tool.
I was making 90 - 95s on every test with the UCertify stuff. So i thought I was ready for the test. I got signed up and went and took it yesterday.
THE UCERTIFY STUFF WAS NOTHING LIKE THE TEST!!!!
It was so different that about 15 questions into the test I knew I wasnt going to pass. The UCertify questions were geared towards stuff you could memorize...rules, what different functions do, what certain characters mean.
The test was 90%...here are 4 queries...which one works based on the given exhibit. They werent just simple one line queries either. I swear one question had a query with a subquery with a subquery and all of them had joins from 4 different tables. The question was so hard to follow what they wanted that it was almost a joke. Alot of the questions asked for 2 answers..."select two correct answers"
I know what to study now but I will definitely NOT be using UCertify to study with anymore.
If you are studying the best thing to study is what breaks a query, look for questions that ask you to figure out whats wrong in the query or what the outcome will be.
Know a LOT about grouping, sorting, subqueries, and being able to determine what a query will return.

Hi,
I took the SQL Fundamentals test too, although the one I took was for 9i.
I too prepared for it using uCertify and a OUP book (Jason Couchman), and like you, I was getting around 85-95% on the uCertify tests. Furthermore, their Final Test said that this is harder than the actual exam, so when I got over 90%, I was very confident. However, like you, when I did the actual test, it was a lot harder, and eventually I passed with a much lower mark than I expected (pass mark was 37, I got 41). So I was definitely disappointed with uCertify.
I do believe they say that "pass or your money back", so I would advise you to ask them to refund you!!!
Good luck in your next test.

Is the only 1Z0-051 SQL Fundamentals I certification useful/recognised in the international labour market?

Hi,
I've been studying for passing the 1Z0-051 "SQL Fundamentals I" exam before taking the 1Z0-144 "Program with PL/SQL" exam and so I wonder if the only (for the moment) "SQL Fundamentals I" certification may be considerated useful/recognised in the international labour market or if it's "only" an intermediate certification for taking the "Program with PL/SQL" exam.
I ask for that 'cause I wonder if once I'll have taken the "SQL Fundamentals I" certification, this might be added in my curriculum or if it's just an intermediate certification
Thanks!

...The SQL exam 051 or 061 by itself doesn't have value. But the SQL Expert exam 047 is a standalone certification exam.
I really don't like the statement that the SQL Fundamentals exams have no value. Passing the exams will not earn a certificate. That is not the same thing as having no value. I am in the final stages of hiring an assistant to act as a backup for me. For several reasons the company decided to hire a recent college graduate with minimal (read almost zip) Oracle knowledge. I plan to assign them a set of reading material to study and certification exams to prepare for. I wrote an article detailing the specific steps on Certification Magazine here:
How to train your assistant: Certification makes the minion - CertMag
The very first test I will have them work towards is 1Z0-051. If that test 'had no value', why would I bother doing this? The SQL Expert Exam (1Z0-047) earns a certification and so obviously is'the more valuable exam, right? Wrong (at least in my opinion). The SQL Fundamentals exam has a better coverage of the basic SQL elements that I need to be confident my assistant has learned. After my backup has completed all of the certifications listed in the above article, I may well have him move on to some more advanced exams, including 1Z0-047, among others. However, much of the SQL Expert exam content is on seldom-used elements of the language. I don't think I have ever used the ROLLUP, CUBE, or GROUPING SETS operations for real-world work. Likewise I cannot recall having a need for multitable INSERTs. I have never had a need to set a column to UNUSED. I think I've used regular expressions less than five times in twenty years. I use CONNECT BY PRIOR more than that, but still seldom enough that I often Google the syntax when I need to write a hierarchical query.
In short -- why would I bother making them spend time studying aspects of SQL that they almost certainly won't use very often. I need them to be knowledgeable about the SQL syntax that they will be using on a daily basis. That's what the SQL Fundamentals exam contains and that is why that exam is more valuable for people just starting out with the Oracle database.

May i go for sql expert(1Z0-047) exam or 11g sql fundamentals 1(1Z0-051)

Hi all,
Please suggest me, may i go for sql expert(1Z0-047) Test or 11g sql fundamentals 1(1Z0-051) Test with
oracle Administration 1(1Z0-042) Test.
Which will be the best option.
Thanks & Regards

You may use either exam along with the Oracle Administration 1 (1Z0-042) exam if your goal is to get a 10g DBA OCA credential.
The SQL Expert exam is quite a bit more challenging than the SQL Fundamentals exam. On the other hand, the SQL Expert exam gives you a separate SQL Certified Expert credential. If you can pass it, you should take the SQL Expert exam.

1Z0-051 SQL Fundamentals 1 Exam Guide Problem with loading HR schema

Hi,
I’m new to Oracle Databases and have started studying with Oracle Press 11g SQL Fundamentals 1 Exam Guide 1Z0-051.
The book is good except the problem I have is the HR schema they talk about is made up off seven tables (Countries, Departments, Employees, Job_History, Jobs, Locations and Regions).
But the HR schema that I get is only made up off 4 tables (Bonus, Dept, Emp, Salgrade).
Can anyone who has used this book please advise what I’m doing wrong and how I can get the correct Schema please.

Hi,
Well I haven't used that book but with whatever little I know , I shall try to attempt the question.
There was an ancient schema for Human Resource, SCOTT which is haivng 4 tables only. Since 9i, there were an introduction of new schemas like HR ( Human Resource), OE( Order Entry) and so on. So the book is referring to that.
Now when you create the database using Database Configuration Assistant, there comes an option with a check box, that do you want to create sample schemas or not? If you select that option, you get all these schemas in your db. If not, you only get the old SCOTT schema.
If you have missed creating these schemas( which I belive is the case) than you need to manually create them. Here is the description for how to create them manually.

Where/how to download employees etc tables in SQL Fundamentals I, II books

I just installed Oracle 10g on my Windows XP. Wondering where and how to download those tables in the Oracle Database 10g: SQL Fundamentals books? So I can follow the books' examples.
Thanks in advance,
Dennis

Hi,
When you install the DB and use the option to create a db (or create a db using dbca) you have a option to select if you want to install the example schema.
Here you can get more information about the sample schema:
- http://www.idevelopment.info/data/Oracle/DBA_tips/Database_Administration/DBA_33.shtml
- http://www.dbasupport.com/oracle/ora10g/sampleSchema.shtml
- http://www.adp-gmbh.ch/ora/misc/sample_schemas.html
The schema owner of table employees is hr. If you are connect as sys you need to run DESC HR.EMPLOYEES to see if this schema is installed.
to import it use:
imp system/xxxx file=xxxx.dmp log=xxxx.log fromuser=hr touser=hr
You can install it mannualy:
Run scrip mksample.sql. The first two arguments are the password for system and sys, respectively, followed by the six passwords for hr, oe, pm, ix, sh and bi, respectively, followed by the default tablspace and the default temp tablespace. (Take a look in the first link I post above to see the details of this kind of installation ;) )
e.g:
@?/demo/schema/mksample passwd_system passwd_sys pw_hr pw_oe pw_pm pw_ix pw_sh pw_bi users temp c:\temp\ora_schema_log

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...
Page 2-12
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?*
Page 2-35

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,

Where to find hr_main.sql?

Hi all,
I want to create sample schemas in 10g.
But i can not find the hr_main.sql in $ORACLE_HOME/demo/schema/human_resources
/u01/oracle/product/10.2.0/demo/schema/human_resources> ls -ltr
total 8
-rw-r----- 1 oracle dba 2733 Aug 29 2002 hr_code.sql
Q: where else to find this sql?
thanks

Hello all,
I have the same problem in an Oracle 10g R2 environment:
the book "Sample Schemas" says:
All scripts necessary to create Human Resource (HR) schema reside in $ORACLE_HOME/demo/schema/human_resources.
You need to call only one script, hr_main.sql, to create all the objects and load the data. Running hr_main.sql accomplishes the following tasks
But there is only "hr_code.sql" as already written by SZ.
Also the solution described here can't work: there is no file "hr.jar" on the companion-CD. I searched for all "*.jar" files on the disc...a lot of files, but no "hr.jar"...
The "Samples Schema" book says here in chapter 1: The scripts are included in the companion directory on the installation medium..
It's the first time for me that it seems that the documentation is not telling the truth... ;-)
Does anyone know what's up with the scripts as they are described in the "Samples schema" book??
(or is it completely different on LINUX?? Do they not exist on Linux?? That's the OS I use...)
Thanks for your help in advance!
