Sample Database for teaching PL/SQL

I am looking for a sample database which would contain sample procedures, functions, triggers, etc. for teaching a PL/SQL class. Any ideas?

What I am specifically looking for is sample procedures, functions, triggers, etc. to use for illustrative purposes. Otherwise I need to write a whole bunch for Powerpoint slides that I use in the class. If they were alredy there I could use SQL*Plus or Procedure Builder to display and discuss.
I would be very interested in seeing the Human Resources sample database. Would you know what release it is included in? We are using 8.1.7
SCOTT schema exists on all oracle platforms (if not created by default, can be created by using the script
${ORACLE_HOME}/rdbms/admin.scott.sql.
Newer versions of Oracle come with additional example schemas like Human Resources, Order Entry,
Sales History, Shipping etc...
If not installed by default, you can use Database Configuration Assistant to install these example schemas.

Installing Sample Database for OPM Release 11.0.3

Installing Sample Database for OPM Release 11.0.3
I already installed OPM Application on an existing Vision Database VD11, and I followed the instructions to install OPM application up to end.
I logged to Oracle Application as user: SYSADMIN/SYSADMIN, and I checked
in the System Administrator Responsibility\Security\Responsibility all the OPM
Responsibilities exisit, I assigned all OPM responsibilities to a user: OPERATIONS/WELCOME (OPM Inventory, OPM Financials,....etc), I signed to
OPERATIONS user, I select one of the OPM Responsibilities (OPM Inventory), here if I try to do some query it gives me error: no records quaried, Okay that's mean I have to install Sample OPM Database Release 11.0.3
My question:
In the Sample Database for Apps R11 for OPM CD, I followed the instructions in the sample.pdf file to create a Database, but that .pdf file to create a new SID while I have already installed SID (VD11).
My request is to import the data for OPM from sample11_03.dmp to my existing
VD11 Database ?
The initNAME.ora file in this CD contains roll_back segments (r01,r02,r03,r04)
while initVD11.ora contains these Roll_back segments (rbs1,rbs2,rbs3).
How I can modified the initNAME.ora and initVD11.ora to import the data for
OPM from sample11_03.dmp to my existing VD11 Database or I don't know if it
should be in a different SID ??
Are there any NOTE to explain how to install Sample Database for OPM in an
existing VD11 Database for Application R11?
Please help will be appreciated.

Create MS SQL Server 2014 instance for TSQL2012 sample database Training kit (70-461)

Hi,
I just bought the Training kit (70-461) Querying Microsoft SQL server 2012. I downloaded Microsoft SQL Server 2014. I have also downloaded the script for the sample database -
TSQL2012.sql.
Basically I want to set up the sample database and practice my SQL queries. How do I log into
Microsoft SQL Server 2014? Basically I am doing this on my home computer. It is asking me for Server type, Server name, and Authentication. Do I have to set up a server instance to run and create the sample database? How?
Thanks.
Peter

Do you see anything in the Server Name at all?
So, in the first drop down you need to select Database Engine.
In the second (for Server Name) if you see anything, then try selecting it.
If there is nothing, try methods described in this article
http://sqlserver-help.com/2011/06/19/help-whats-my-sql-server-name/
to find the actual name.
Then, try choosing Windows Authentication and try connecting. If this would not work, then you do need to try using sa and sa's password. If there is no way to find that sa password, then perhaps it's better to clearly uninstall and re-install. If you want,
I'll move your thread into either 'Getting Started' or Data Access forum as it doesn't seem to be related with Transact SQL.

How can i use a database for practice in DOS

i have some problems in the sqlplus.
My OS is windows2000 server,when i intalled the Oracle 8i
i type a command 'cmd' go to DOS.and type "sqlplus username/password@database"
but always the system say that my database name can't be deal with.
and i want to get a sample database for training SQL statements.How can i get it.
is Oracle 8i have the sample database.

It sounds like your database hasn't been started yet so do this:
Try typing svrmgrl at the c:> -- if it doesn't work you might either have to go to the proper directory or type sqlplus to get an sql:> prompt (I don't remember it's been a while) but the rest I am pretty sure about---
When you get the svrmgr prompt:
use (i think) "connect internal"
and "oracle or Oracle" as password
once you do this
it should say connected
then use: svrmgr:>shutdown -- shutsdown DB
then use: svrmgr:>startup -- starts DB
hopefully then you can access your database through SQL Plus

Sample databases

I am used to working with SQL Server 2005 and now working in SQL Server 2008.
I have used Oracle 10g and 11g in the past but would like to dive into PL/SQL
SQL Server has always provided a sample database called AdventureWorks and now provides many editions for training and example purposes.
Is there anything comparable to this in the Oracle World? I have failed to find anything like this anywhere.
I do realize that there are databases installed with Oracle (SQL Server comes with builtin DBs as well) but nothing seems to compare to Adventure Works. It would be nice to learn Oracle and middle tier applications against some real data.
I would appreciate any direction on this as to where i can obtain sample databases for Oracle.
Thanks

ThanksOralce is not Sql Server and I believe, in Sql Server, the concept of a database within database is called a Schema of a database in Oracle. So Oralce does supply some sample schemas that one can install in his database and use this data for playing around.
Here is the doc link to give the info that how one can install these sample schemas,

How to create a database for sample code from Tutorial/Book?

I want to try out the sample code from [http://shop.oreilly.com/product/0636920013471.do] for the book SQL Pocket Guide 3rd Ed.
I have downloaded the oracle vm/appliance for oracle 11g2 and I have started sqlplus as sysdba.
I'm feeling overwhelmed with these links describing how to create a database:
[http://www.adp-gmbh.ch/ora/admin/creatingdbmanually.html]
[http://tldp.org/HOWTO/Oracle-7-HOWTO-3.html]
[http://www.adp-gmbh.ch/ora/admin/creatingdbmanually.html]
(1) What is the command to list the existing databases?
(2) What is the command to delete an existing database?
(3) When creating a new database with the create database command, is it necessary to specify the logfile, character set, national character set, datafile, sysaux datafile, undo tablespace, temp table space? Do these have reasonable defaults? I'm not sure what proper directories are to specify for Linux and the examples are for windows.
Can someone give me a simplified create database command to create a database called 3rdEdPocketGuide? Should I follow the example at [http://tldp.org/HOWTO/Oracle-7-HOWTO-3.html] and instead of orcl use 3rdEdPocketGuide?
(4) What command do I use to execute the script that comes with the book SQL Pocket Guide 3rd Ed? This is the script that has all the drop table, create table and insert commands in it.
(5) What command do I use in sqlplus to set the current default database prior to running this script? Perhaps this is the connect command? I don't want my script to create tables in the system database.
(6) I tried the command "connect 3rdEdPocketGuide" and it prompted for a password! Yikes! What password? Do I need to specify a password when I create a database? I cannot tell if I have successfully created such a database or it is just prompting me for a password to thwart malicious users. Is it is possible to create databases which don't require a password or maybe a zero length password?
Thanks

Everyone:
Do I need to create a user using SQL*Plus first so I can login with "Oracle SQL Developer" so I create my database called? What would be the "create user" command I would execute?
OK, so I run sqlplus and issue these commands
create user siegfried identified by abc ;
grant connect to siegfried ;
connect siegfried/abc;
Now, how do I create a database? In Microsoft SQL Server one has to create a database first and if you just start creating tables without creating a database first, the tables will be created in the system database and this is usually undesirable.
Sometimes a database is known in the java connection string as the catalog. Is there any such analog in oracle SQL plus?
So now what do I do? I want to create a bunch of tables using my script I downloaded from 3rd Ed SQL Pocket Guide. Does my new user "siegfried" have the right to create tables? I guess I could try but I don't want to create tables in the system database.
I noticed I can also use "Oracle SQL Developer" to connect with my new "siegfried" account. It seems that I should have been able to connect with sysdba... strange.
So now I am connected in the "Oracle SQL Developer" and I see no list of databases.
Thanks!

What are the ODBC connect details for the HR sample database?

I have installed Oracle Express on Ubuntu 8.10 and read the Getting Started tutorials. Everything worked fine.
THE DSN
I need to connect via ODBC, to start with to the HR sample database on my PC.
The Getting Started tutorial says the userid and password are both hr, but what is the data source name (dsn) to be used with the SQLConnect?
THE INIs
The ini files below are the result of googling, not of any insight on my part.
/etc/odbcinst.ini
[OracleExpressdrv]
Driver = /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/libsqora.so.10.1
Description = Oracle 10g express driver
/etc/odbc.ini
[hrdsn]
Driver = OracleExpressdrv
Application Attributes = T
Attributes = W
BatchAutocommitMode = IfAllSuccessful
CloseCursor = F
DisableDPM = F
DisableMTS = T
DSN = TestDSN
EXECSchemaOpt =
EXECSyntax = T
Failover = T
FailoverDelay = 10
FailoverRetryCount = 10
FetchBufferSize = 64000
ForceWCHAR = F
Lobs = T
Longs = T
MetadataIdDefault = F
QueryTimeout = T
ResultSets = T
# ServerName is TNS_alias_from_tnsnames.ora
ServerName = OraDB
SQLGetData extensions = F
Translation DLL =
Translation Option = 0
UserID = ken
THE ENVIRONMENT
Before running my odbc test program I issued
LD_LIBRARY_PATH=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib;export LD_LIBRARY_PATH
and checked via env command that the ldlibpath actually had been set correctly.
After SQLConnect received the following error:
Usage error: SQLConnect: dsn=hrdsn, user=hr, password=hr <<< output by my test program
1: st=IM002, nerr=0, msg=
[unixODBC][Driver Manager]Data source name not found, and no default driver specified
The first part of the error message hints at there being something wrong with dsn=hrdsn. I don't understand the second part 'and no default driver specified'.
I am totally stuck. Advice would be most appreciated.

Oracle® Database Express Edition Installation Guide for Linux talks about Compiling the Oracle ODBC Driver Demos. It tells you to download and install the unixODBC DriverManager from unixODBC. On Ubuntu this is already preinstalled and/or available via the Synaptic Manager. It also instructs you to run a makefile demo_xe.mk to build an odbcdemo program. The makefile did not work for me (hundreds of compilation errors), but I looked at the odbcdemo.c code and could see that dsn=TESTDBDSN for user=hr and password=hr. In other words, by luck the demo program seems to be connecting to the HR sample database.
I changed the /etc/odbc.ini file to:
[TestDBDSN]
Application Attributes = T
Attributes = W
BatchAutocommitMode = IfAllSuccessful
CloseCursor = F
DisableDPM = F
DisableMTS = T
Driver = OracleExpressdrv
DSN = TestDBDSN
and also in my test program which now produced the following error:
Usage error: SQLConnect: dsn=TestDBDSN, user=hr, password=hr
1: st=IM004, nerr=0, msg=
[unixODBC][Driver Manager]Driver's SQLAllocHandle on SQL_HANDLE_HENV failed
which shows that the unixODBC driver manager has loaded the driver and that the driver immediately encountered problems.
The sql calls issued before the SQLConnect("TestDBDSN", "hr" , "hr") were OK, i.e. these:
rc0 = SQLAllocHandle ( SQL_HANDLE_ENV , SQL_NULL_HANDLE , &henv ) ;
rc = SQLSetEnvAttr ( henv, SQL_ATTR_ODBC_VERSION , *)SQL_OV_ODBC3 , 0 ) ;
rc = SQLAllocHandle ( SQL_HANDLE_DBC , henv , &hdbc ) ;
SQLSetConnectAttr ( hdbc , SQL_LOGIN_TIMEOUT , (void*)5 , 0 ) ;
However, the error appears after SQLConnect and yet the rc0 was reported as OK.
The error message 'Driver's SQLAllocHandle on SQL_HANDLE_HENV failed' is totally unhelpful to me as a user since I don't know the conditions that lead to failure. I really think this calls for some documentation. Such documentation should be complete, self-contained and correct and give ALL OPERATIONAL steps, i.e. I want to know exactly what I have to do. Ambiguous English often referring to undefined terms is not what Oracle beginners like myself want.
I don't know if this is a bug. It is so fundamental that Oracle ODBC driver writers could/should not have got it wrong. The connect does not even start.
I have googled for hours, but every lead has failed.
I don't want to give up on this. What can I do?

Is there any well designed sample database availabe for download ?

Hi
Thank you for reading my post
I get the Oracle Express 10g and now i am looking for a good database with some test data inside it
to practice some tuning and sql commands.
is there any (rather big ) sample database available for download ?
Thanks

Hello,
XE ships with the Sample Application that includes the HR schema with some objects to work on. By default, the HR user account is locked so you need to unlock it first. It's usually a good place to start as many current and future documentation based on XE will include examples from this schema.

New sample database to work through admin 1 and Introduction to SQL

I'm very new to Oracle, even databases for that matter. Just completed the Introduction to sql and dba admin 1 courses. I would like to work though all the course material at home.
I have installed oracle 11g on my Windows 7 machine as well as SQL developers 3. I have unlocked the HR user and pointed the java.exe to the correct path
How do I set up or startup the sample hr database so I can work? and how do I make a connection to that database with SQL developer, in order to run SQL's
Please help!
Dave

Pl identify the exact versions of "11g" and "Windows 7".

Which is better for performance Azure SQL Database or SQL Server in Azure VM?

Hi,
We are building an ASP.NET app that will be running on Microsoft Cloud which I think is the new name for Windows Azure. We're expecting this app to have many simultaneous users and want to make sure that we provide excellent performance to end users.
Here are our main concerns/desires:
Performance is paramount. Fast response times are very very important
We want to have as little to do with platform maintenance as possible e.g. managing OS or SQL Server updates, etc.
We are trying to use "out-of-the-box" standard features.
With that said, which option would give us the best possible database performance: a SQL Server instance running in a VM on Azure or SQL Server Database as a fully managed service?
Thanks, Sam

hello,
SQL Database using shared resources on the Microsft data centre. Microsoft balance the resource usage of SQL Database so that no one application continuously dominates any resource.You can try the
Premium Preview
for Windows Azure SQL Database which offers better performance by guaranteeing a fixed amount of dedicated resources for a database.
If you using SQL Server instance running in a VM, you control the operating system and database configuration. And the
performance of the database depends on many factors such as the size of a virtual machine, and the configuration of the data disks.

Is it possible to have different authentication mode for SQL Server Database Engine and corresponding SQL Server instance?

Hi,
I have installed the x64 SQL Server 2008 R2 Express with default settings and run MBSA 2.3 (using default settings too). It shows three SQL Server instances: MSSQL10_50.SQLEXPRESS, SQLEXPRESS and SQLEXPRESS (32-bit). For the first, authentication
mode is Windows, for the rest two - mixed. Here https://social.msdn.microsoft.com/Forums/sqlserver/en-US/03e470dc-874d-476d-849b-c805acf5b24d/sql-mbsa-question-on-folder-permission?forum=sqlsecurity question
about such multiple instances was asked and the answer is that "MSSQL10.TEST_DB
is the instance ID for the SQL Server Database Engine of the instance, TEST_DB", so in my case, it seems that MSSQL10_50.SQLEXPRESS is the instance ID for SQL Server Database Engine of the SQLEXPRESS instance.
I have two questions:
1) How can it be that SQL Server DB Engine instance has different authentication mode than corresponding SQL Server Instance?
2) Why 32-bit instance reported although I installed only 64-bit version?
Also, this https://social.technet.microsoft.com/Forums/security/en-US/6b12c019-eaf0-402c-ab40-51d31dce968f/mbsa-23-reporting-sql-32bt-instance-is-running-in-mixed-mode-when-it-is-set-to-integrated?forum=MBSA question seems to be related to this
issue, but there is no answer :(.
Upd: Tried on clean Windows 8 installation and Windows 7 with the same result.

Because I DO NOT want the three people who will be having access to the production SQL Server to also have access to the primary host ProductionA. Since I have to allow them to RDC into the box to manage the SQL Server, I figure why not create
a separate VM for each one of them and they can RDC into those instead.
Does this make any sense?
Any tips are greatly appreciated. The main reason for doing this is because the three people who will be accessing the box, I need to isolate each one of them and at the same time keep them off of the primary ProductionA.
Thanks for your help.
M
Hello M,
Since you dont want the 3 guys to have access to Production machine A.You can install SQL Server client .By client i mean SQL server management studio(SSMS) on there local desktop and then create login for them in SQL Server.Open port on which your SQL server
is running for three of the machines so that they can connct.Now with SSMS installed on each machine each can connect to SQL server from there own machine.
I would also like you to be cautious with giving Sysadmin privilege to all three of them ,first please note down what task they would do and then decide what rights to be provided.
Your option will also work but you need to create 3 VM for that .Which is more tedious task.
Hope this helps

Help with structuring SQL databases for multiple photo galleries..help!?!

Hello all,
As a new PHP/SQL developer I have found great technical assistance from both this forum and from David Powers and his wonderful books. I am at a crucial point in my web development and although I believe I know which direction I need to go, I am still uncertain and so I appeal to you all for your help, especially David Powers.
The website I am building is one which will house many photo galleries. I was able to successfully modify the code provided in David Powers’ book ‘php Solutions’ so that I got the photo galleries constructed and working in the manner I desired.
That being said, a person browsing my website will be presented with a link to see the photo galleries. There will be five (5) categories in which the photos will be separated, all based on specific styles. Now that I have the galleries working, I need to know how to structure things so that I can create a page, like a TOC (table o’ contents) that shows all photo galleries by displaying a thumbnail image or two along with the description. Perhaps I’ll limit the TOC page to only show the latest 25 galleries, arranged with the most current always on top.
The way I have my galleries set up, I have a separate database for each one, containing the photo filenames and other relevant data. To build my TOC structure, should I have an overall database that contains each gallery database filename along with category? This is where I have no idea what I’m doing so if my question sounds vague, please understand I have no other idea how to ask.
The site will grow to the point of having hundreds, if not thousands of photo galleries. I simply want to know how to (organize them) or otherwise allow me to build a method to display them in a TOC page or pages.
I know this is a bit dodgy, but with some info and questions back from you, I feel confident that I should be able to get my point across.
Lastly, I am still developing this site locally, so I have no links to provide (though I feel that shouldn’t be necessary right now).
Many sincere thanks to you all in advance,

bregent,
I'm chewing this over in my head, reading up on DB's in 'phpSolutions' and I think that things are slowly materializing.
Here is the structure of the website that I have planned:
MAIN PAGE
User is presented with a link on the main page to select photo galleries (other links are also present). Clicking the link takes them to the Category Page.
CATEGORY PAGE
On this page, the User will then have 5 choices based on categories (photo style). CLicking any of these 5 links will take them to respective TOC pages.
TOC PAGE
On this page, the user is greeted with a vertical list of galleries or photosets; one to three thumbs on the left, a small block of descriptive text on the right (ideally containing date/time info to show how recent the gallery is). Newest galleries appear at the top. Eventually, when there are tens or hundreds of galleries in any given catrgory, I'll need to adopt a method for breaking up the qualntity in groups (we can pick 20 for example) that can be scrolled through using a small navbar. This will keep the TOC Pages from getting endlessly long and avoid endless scrolling. User selects a gallery on this page to view.
THUMBNAIL PAGE
On choosing a gallery, a thumbnail page is generated (I have this working already)
IMAGE PAGE
On selecting any thumbnail in the grid, the user is taken to the full-sized photo with a navbar and photo counter at the top. Navlinks allow forward and back, a link to the first image, a link to the last image and one link back to the thumbnail page. (I have this working already).
I provide this info in an effort to help understand the basic structure of my site. The description above is as close to a step-by-step illustration as possible.
Thank you!
Sincerely,
wordman
