SQL practice database

Hi FOlks,
I installed the companion CD to 10g. How do I change databases to practice using PL/SQL from my SQLplus application?
Thanks
BRuce

As Justin mentioned you will need to unlock the HR user/schema. Also, before you ask... yes, user and schema are synonymous. A user or schema, whatever you call them will have associated tables in them. And tables that are under (or are created by) that user belong to that user only.
When you signed in as SYSMAN and you looked up the tables, that query showed you the tables belonging to SYSMAN, not HR.
Login in to HR and you will see the tables(and other objects) belonging to HR.
Good luck and fun adventure.

Moving an existing SQL Express Database to SQL Server 2008 (included in SBS2011) help!

I have software that uses SQL 2005 right now, but the database is close the max size (4 GB). I have SBS2011 installed and it includes SQL 2008 and SQL 2008R2. I want to move the database to the 2008 version that can that can handle larger databases.
I'm not an SQL expert, but have some experience with it. What I need are some directions on how to make this change without causing any problems with the system, including setting up the SQL server so it will have all the same settings as the old one.
This is a practice management software.
Thanks in advance for any help. Harvey

Hi,
I think you can upgrade SQL Server 2005 to later version of SQL Server rather than moving the existing database to another SQL Server instance.
Upgrade SQL Server 2005 SP2 Express to SQL Server 2008 R2 Express and SQL Server 2005 SP4 SQL Server 2012 Express. And you will have maximum 10 GB per database.
Make sure that your operation system is compatible with SQL Server
version which you want to upgrade to. For more information, see:
http://msdn.microsoft.com/en-us/library/ms143506(v=sql.105).aspx#SSE_x64
It is possible to backup and restore the database on another instance and modify the database path in the software.
You need to test it in your test environment first before making changes in the production environment.
In addition, you need to consult with the software developer and see if there is any potential issue.

Best practise for creating an application that connects to a SQL Server database

I have created an application that connects to a SQL Server database and views information using a datagrid and performs several updates when a button
is selected.
I have created a SQLcontrol.vb using the following code:

I am fairly new to vb.net and have read a few books and followed a few tutorials on youtube, what I would like to know is, are there any disadvantages
to the way I have connected to a SQL database using the SQLControl.vb. A lot of the vb books include data adapter and dataset within the form, I'm not sure if I'm following best practice by have the connection details outside of the form.
My other question is, I have created two connections in the SQLControl and call these connections within the same form using the same data adapter
and dataset. It all works fine but I just wanted to know of any potential issues?
Public SQLCon As New SqlConnection With {.ConnectionString
= "Data Source=;Initial Catalog=;Integrated Security=True"}
'connection 2
    Public SQLCon1 As New SqlConnection With {.ConnectionString
= "Data Source;Initial Catalog=;Integrated Security=True"}
Thanks

My other question is, I have created two connections in the SQLControl and call these connections within the same form using the same data adapter and dataset. It all works fine but
I just wanted to know of any potential issues
1) You are not using Sepration of concerns for a solution that is doing data access, like using a DAL.
http://en.wikipedia.org/wiki/Separation_of_concerns
2) You are directly issuing SQL commands at the UI, leading to sql injection attacks.
3) You are not using a UI design pattern, which leads you to tightly couple database activity to the UI.
http://www.codeproject.com/Articles/228214/Understanding-Basics-of-UI-Design-Pattern-MVC-MVP
@System243trd, parameters are important to prevent SQL injection attacks (people will insert SQL commands into the database if you do not perform basic checking of what you are passing to the database). If you write a stored procedure try to make
the variables the correct SQL server data type to avoid problems later of people trying to call it directly.  Darnold924 is right, I see no code to prevent against SQL injection attacks. In addition, during development in some instances LocalSQLDB
database system is used and during deployment you usually need to use the production SQL server database. Moreover, Linq-to-SQL is used on Windows Phone 8.1 and it is required for phone development later and so I highly recommend learning
it if you plan on developing windows phone applications.
@System243trd, If you want the code for the windows phone app I think it uses the MVVM model or that might be for universal apps or regular windows phone apps. I have been using the windows phone Silverlight pivot or panorama template (it might
be pieces of both). I've already submitted to the windows phone marketplace and it had to go through certification first. I plan on later making an article on it but I need to first fix one or two simple problems I have with it. Here's a link to
the source code if you later want to look at the source code (in vb.net):

Connecting BO universes with SAP on a SQL server database

Hello,
The aim is to make a secured connection between a BusinessObjects universe and an SAP system that runs on a SQL server database.
We will have in the nearby future 1 SAP system for several customers (SAP in the clouds). For those customers we want to maintain their BusinessObjects connection with the SAP system as it is for the moment. This means that the customers who are working with their current BO system (5.1.6) connect for the moment between BusinessObjects and their local SAP system via the universe connection (Oracle driver and user). These customers should connect in the nearby future to a central SAP system and only be able to see the data of their own company (based on a client number). Iu2019m wondering if we could use the SAP-authorisation mechanism in order to do so. This would mean that we define an SAP user in SAP and that we define the same user in BusinessObjects and that there is a layer in between (cfr. The sap java connector) that allows a secure connection for a client to only its specific data (based on client number f.i.)
Can you tell me if there exists already a solution for this for BO 5.1.6 or what is the pre-requisite in order to do so. I know that the Best Practices of SAP-Bo use already this kind of mechanism but then we talk about BO XI 3.0 and ECC 6.0 linked via a Java Connector. Does there already exists something like that for the connection between an SAP system (on a SQL server database) and a BusinessObjects 5.1.6 system.
Thanks in advance for your answer.
Thierry Renaer

Hello,
Thank you for your reply. And what about BO XI 3.0? What should we be using?
Ik have been using the SAP Java Connector but I'm wondering if there exists more user friendly (read easily adaptable) tools in order to provide a secure connection between SAP BO XI 3.0 and SAP ECC.
Many regards

SQL Practice

Hello everyone. I have been using SQL for almost a year now and am currently studying for my 70-461 exam. I have the Microsoft training kit book, have read, highlighted, and done most of the exercises, however the best way for me to learn is just constant
practice in multiple scenarios. I was wondering if there is any additional "labs" or practice questions out there that I can use (based off of either the AdventureWorks2012 or the TSQL2012 practice databases) to help further fine-tune my skills in
SQL. I hope within another year or so to get a job specifically working with databases and eventually become a DBA so I want to know this information well.
Thanks in advance!

Dont know if this works for you.. but what I try these days is to look into the transact-sql forums specifically for all the types of good and wierd questions. I try to find solutions for them and most of the time before I could find a solution someone
would have already posted theirs. I then try to compare my code with theirs and try to find how better, easy and simple theirs is.
I am learning quite a lot about coding . I am a hardcore dba and my coding skills arent great. I am learning a lot from the forums.

Can Oracle view refer a table in Sql Server Database

Can a view created in Oracle database refer a table created in SQL Server database. If yes, how do we do it. Code will be very help full.
Again, if yes does it require any special software and what would be price of that software.
Thanks for your response in advance.

You would need to configure Oracle Heterogeneous Connectivity to create a database link to the SQL Server system. This can either be done via the Oracle Transparent Gateway for Microsoft SQL Server, which retails for $15,000 per server at http://store.oracle.com or by configuring Oracle Generic Connectivity and using ODBC to go after the SQL Server data. Depending on the operating system you run Oracle on, there may be a free (or cheap) ODBC driver for SQL Server that could be used.

Trigger to populate table in sql server database

Maybe this isn't the right board to post this in, but here goes:
We have an Oracle 9i database, with a table that get's populated with a new record every minute or so.
We need to take some values from the newly inserted record and populate a table in a sql server database instantly. The people requesting this have not said as much, but I am thinking deletes and updates would need to be the same.
How would it be best to do this? My first thought was a trigger on the oracle table that populates the sql server table via heterogeneous db link.
Any other ideas?
thanks in advance..

How can I connect to SQL server database thru local network by using JSP?

I'm currently doing a project by using JSP..And I need to display record from the SQL Server database in our school's local network. May I know how can I do that? How can I write the code so that I can able to access the SQL Server databsase Throught school's network by using JSP? Please tell me step by step how can I do that. I'm using Tomcat 4.1 as Web Server. And I had J2SE and J2EE installed in my computer.

first you have to establish a ODBC DSN on your computer,
that connects to the database...you can do that from your control pannel.
i assume that the TOMCAT server is residing on your computer....(if the webserver is in other computer then you would have to create a System DSN on the data sources ODBC option in the settings>control pannel of that machine)
then you can use that DSN name to connect to the data base from the class file....for further assistance on how to create the class that access the tutorials in sun site.

How can I get the data array from SQL Server Database?

Hi,
I can write a data array(2D)into a table of my SQL Server Database. The data array was writen to a column with image type. I know a data array is transformed a binary string when writing into database, but I dont know how to get the data array when I fetch the binary string from database.
My question is:
How to transform the binary string into data array? which vi's should I use? I have tried unflatten from string but failed.
Any response is appriciated.

In order to use Unflatten from string you first need to Flatten it
before writing it. Also depending on the database driver, the returned
data may actually not be binary but Hexadecimal encoded ASCII which you
would first have to decode to binray.

How to connect a PDF form to SQL server database through web service?

Hi,
I'm new to LiveCycle designer. I have designed a PDF form in LC designer ES2, which suppose to take a personnel number and retrieve the personnel information from a SQL server database. Currently its working fine with XML data and a search button, but I need to securly connect to a database through web service. I know how to connect to a wsdl file through designer. What I need is a wsdl file to connect the form to database. For this purpose, is there any WSDL code to use as the web service?
I really appreciate your help and advice.

How can I get an accurate count of computers (workstations) logged in to my SQL Server database?

We license our software by number of workstations.
I have a query that I have used for years to get an accurate count of the workstations logged in to my SQL Server database. For simplicity, all users use the same login name/password. This is built in to the script that attaches to the DB. They
have access only to that DB with the exception of
USE [Master] GRANT VIEW SERVER STATE to MyUser
The query that has been working is below:
Basically this relies on the mac address (Master.dbo.sysprocesses.net_addre
SELECT COUNT(Users) AS UserCount FROM (SELECT COUNT(Master.dbo.sysprocesses.hostname) AS Users FROM Master.dbo.sysprocesses LEFT OUTER JOIN Master.dbo.sysdatabases ON Master.dbo.sysdatabases.dbid = Master.dbo.sysprocesses.dbid WHERE (Master.dbo.sysdatabases.name = 'MyDatabase') GROUP BY Master.dbo.sysprocesses.net_address) AS UserCount_1
ss), since both Workstation names and ip addresses can be duplicated.
Recently this has stopped working at a number of customers. Suddenly individual workstations are showing multiple net addresses for the same workstation causing a substantial overcount of users. This may be related to SQL Server 2012 - not sure.
What I need is a very reliable way to get a count of workstations logged in to my database.
If anyone can tell me why I am suddenly getting multiple net_addresses for each workstation and how to prevent that that would be one possible solution.
Otherwise if anyone can give me a rock solid way to get a workstation count other than the above that would be great. Our largest customer is 50 users by the way.
Thanks in advance for any help.
Kim

I think your count is getting skewed because of duplicate rows in sysprocesses because of parallelism. Add DISTINCT to your query:
SELECT COUNT(Users) AS UserCount
FROM
( SELECT COUNT(DISTINCT Master.dbo.sysprocesses.hostname) AS Users
FROM Master.dbo.sysprocesses LEFT OUTER JOIN Master.dbo.sysdatabases
ON Master.dbo.sysdatabases.dbid = Master.dbo.sysprocesses.dbid
WHERE (Master.dbo.sysdatabases.name = 'MyDatabase'
GROUP BY Master.dbo.sysprocesses.net_address) AS UserCount_1
