An SQL guide with a practice database (question)

Can someone point me to a good SQL guide(book in pdf format, for example) that comes with a database for practice and is free?
Thanks

Hi Harkon,
Maybe this,
11g Release 2 (11.2) - SQL Language Reference
11g Release 1 (11.1) - SQL Language Reference

How to migrate an existing Microsoft SSIS deployment if it is decided to replace SQL Server with an Oracle database?

Hi Oracle Gurus!
Currently, I am designing an ETL solution that transforms and loads a lot of data from flat files and sends it to an SQL Server 2008 R2 database for storage. However, at a future point of time, it may be decided to add or even replace SQL Server with an Oracle 11g database.
Currently, I am writing script transforms in C# to dynamically generate SSIS packages to tansform and load the data into SQL Server. But considering that in future, an Oracle 11g or 12c database might be added to, or replace the SQL Server database, how do I make my script transforms (or whatever else I am developing currently for SQL Server) reusable to the extent possible?
Or more precisely, what steps do I take, from an Oracle point of view, to ensure that any future migration of data to an Oracle database would be smooth to the extent possible?
Looking up to my Oracle Gurus for enlightenment in this matter!

When you're writing your on C# code to load data into the SQL Server you have to modify the routines so that they will work with Oracle.
One approach is to use the extproc agent which would allow you to directly call external programs with all the logic in it to perform the load of your files and to put the data into the Oracle database. Another option would be to use utl_file package (or equivalents) which will allow you to open external files from your Oracle database and to directly read its content and then to pass it to the related tables.

SQL Query with MS-Access Database

Hi,
I have linked my oracle database with MS-Access via a DB LINK. i can access the data from MS-ACCESS, but i have a problem that when i specify the column name or define a where clause in my query it gives me the error ORA-00904: invalid identfier ..
This query fetch the data without any problem SELECT * FROM TBLREPORT@M_ACCESS but when i run SELECT EMP_ID FROM TBLREPORT@M_ACCESS it gives me the error i mentioned above. (Column name have No problem or mistake of spelling even CASE)
also when i try to put where clause in the query it gives me same error SELECT * FROM TBLREPORT@M_ACCESS WHERE EMP_ID = '100' (Error)
is there any change in SQL query for ACCESS database ??
any clue
Regards
Rehman

Are column/table names in access case sensitive? Issue
DESC TBLREPORT@M_ACCESS If column EMP_ID actual name shows up in mixed/lower case, enclose it in double quotes and use the exact case. E.g., if column name shows up as Emp_Id, use:
SELECT "Emp_Id" FROM TBLREPORT@M_ACCESSSY.

1 SQL instances with several archive Databases using all AWE RAM memory of server

Hello,
I just migrated my accounting system to a new SQL Server deployment of the software.
We just purchased the expensive SQL Server enterprise to accomodate.
I have some replicated databases to of lower priority that I put on the same instance that we occasionally query. I also imported a 70GB old archive DB that we on very rare occasions. We are not concerned about performance on these databases
as we are about the accounting DB on the same instance.
The MAX memory was set to unlimited on that instance. As soon as I put in this monster 70GB archived databases the AWE memory usage used up my full 30GB of RAM.
Is there a way to set the memory usage so the archive databases do not get loaded into the AWE but still the critical accounting system DB on the same instance is taken care of?
Or do I have to shell out another $3-6k for a separate instance? SQL Server Express has a 4GB limitation and one of the backup DB we don't really care about is 20GB replicated from Azure.

Hi,
>>70GB archived databases the AWE memory usage used up my full 30GB of RAM.
How did you checked that Archived database is using 30 G did you used sys.dm_os_buffer_descriptor.Do SQL server have locked pages in memory
SQL Server bring pages in memory if it is requested ,if you access Archived database heavily its bound to take memory but if yous top accessing it and access your other database SQL server will flush out pages of archive IF REQUIRED.
SQL server manages memory dynamically so I guess you do not need to worry
>>s there a way to set the memory usage so the archive databases do not get loaded into the AWE but still the critical accounting system DB on the same instance is taken care of?
No ,there is no way buffer pool is shared region

How to use sql request with Jdev and database connection

Hello,
I have a login page with simple username and password inputsecret text and a button validate! I would like, when the user click on the validate button, to check in the database that the user and password matches. I've done the "Method BIndind..." with the commandButton_action and the database connection works fine.
How can I use an already existing procedure, say authenticate, wich is stored in the database to authenticate my user ?
Do I have to create a jdbc connection in java even if I've done the connection with the "create new database connection" wizard ?
String s1 = "jdbc:oracle:thin:@address:1521:ORCL";
System.out.println( "Connecting with: " );
System.out.println( s1 );
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
this.conn = DriverManager.getConnection( s1,"user","pass");
thanks for your help

Creating a connection to the DB in JDeveloper doesn't mean that your application is now connected to the DB - so yes you do need to create a connection to the database using JDBC.
One note - if you are trying to do a database user authentication the following is probably the better way to go about it:

How to Run SQL Tuning Advisor on the SQL statement with SQL_ID?

Can you give the steps to run the SQL tuning advisor on the SQL statement with SQL_ID?
Database version: 10g Release 2

Hi,
You can use either the automatic SQL tuning features that are accessible from Enterprise Manager Database Console on the "Advisor Central" page or trough SQL*PLUS using the DBMS_SQLTUNE pakage:
-- creating the tuning task
set serveroutput on
declare
l_sql_tune_task_id varchar2(100);
begin
l_sql_tune_task_id := dbms_sqltune.create_tuning_task (
                          sql_id      => '<your_sql_id>',
                          scope       => dbms_sqltune.scope_comprehensive,
                          time_limit => 60,
                          task_name   => '<your_tuning_task_name>',
                          description => 'tuning task for statement your_sql_id.');
dbms_output.put_line('l_sql_tune_task_id: ' || l_sql_tune_task_id);
end;
-- executing the tuning task

Database setup with MySQL and PHP question

Hello all,
I recently had a problem getting a report to work for a site I was updating. This site is written in PHP with a MySQL database. The application is to track customer calls to auto repair stores. The database has a lot of foreign keys because they wanted to update information in only one spot and have multiple records be updated all at once. So, I've got all the information from individual calls saved in the call_log table, and have foreign keys to reference information in other tables (for example this table lists what store received the call referencing the store table). If a store changes locations, they want to have reports automatically update with the new address, connection to conversation number, etc.
In one of the responses to my question on how to get this report to work, I was told that this could be done without using foreign keys (by Normalizing the database using mapping tables). I am still a newbie to MySQL, and after looking though a lot of manuals, tutorials, and forum posts, I am more confused now than ever.
I got the report to work using the foreign keys, but I would like to learn what I should have done with the database (and how to get the information displayed).
So for example one report would be displaying the following:
           Store                                                      Reason for the Customer Call
                                           breaks             oil change            shocks              tune up         total calls
5636 - Bloomington                  2                       4                        0                       2                   8
8875 - Duluth                           1                       6                       4                        8                  19
with links on the store name to pull up the information on that specific store. How would I change the database (listed below) to do this without foreign keys? Any help would be greatly appreciated.
call_log             (table that contains the following:)
call_id
conv_number

camp_type         (foreign key to the campaign table so it displays the campaign_id)

Thank you very much.

Frankly, that is way to much of a question to be answered in detail on a forum... There's a lot involved and a lot of general database understanding required. I would highly recommend:

SQL 2005 with database compatibiltiy level set to 80

I am working with a new client transferred to us and they have been having performance issues, particularly with an add-on solution. I have been looking as some of the database settings and noticed that the database compatibility level was set to 80 - SQL 2000 when they are running on SQL 2005 with SAP B1 2007, PL 44. Would having this set to 80 have any impact on performance? Is it suggested to absolutely set the compatibility level to 90?.
Thanks to all

Hi,
As per the SQL Administration guide, you have to choose collation setting of: SQL_Latin1_General_CP1_CI_AS when installing MSSQL 2005 Server.
In order to check what the collation is set to in your server, please run the following query:
select SERVERPROPERTY ('collation')
(This query gets the collation settings of MSSQL Server's System Database "Master")
Expected answer : SQL_Latin1_General_CP1_CI_AS
As MSSQL 2005 Server is already installed with collation SQL_Latin1_General_CP850_CI_AS, kindly follow the steps below:
Change your server collation to SQL_Latin1_General_CP1_CI_AS
You can find Microsoft's instructions for changing an SQL server collation here:
http://msdn2.microsoft.com/en-us/library/ms179254.aspx
Note: The collation settings of Database "Master" needs to be changed only. All SAP Business One Databases must not be changed! They must remain on SQL_Latin1_General_CP850_CI_AS.
If you need any clarifications with this process please refer to an Expert Empowerment Session "SQL 2005 Server Collation settings" at https://websmp203.sap-ag.de/~sapidb/011000358700000050892007E/ or http://service.sap.com/smb/sbo/support -> Archive: Empowerment Sessions.
If you have any Service pack for MSSQL Server installed, but the Service pack is not included into your DVD MSSQL Server, do as follows:
1. Uninstall Service pack
2. Change Collation Settings as per Expert Empowerment Session
3. Install Service pack again
Hope this is helpful!

Database best practice theoretical question

Hi Forums
I wasn't sure which forum to post this under- general non-specific Database question.
I have a client server database app, which is working well with a single network client currently. I need to implement some kind of database record locking scheme to avoid concurrency problems. I've worked on these kind of apps. before, but never one this complicated. Obviously I've scourged the web looking into this, but found not too much good reference material.
I was thinking of making some kind of class with several lists- one for each table that requires locking having record locks whilst transactions are occuring. Then having clients request locks on records, then release locks when they are finished.
I'm wondering if client requests a lock..then crashes without releasing locks. Should there be a timeout set to enable server release record? Should the client be polling the server to show its still working on the record? This sounds a mess to me!
If anyone can direct me to some good reference material on this I would appreciate it.

FM
EDT* OK now I feel silly! Theres a great article on [Wiki |http://en.wikipedia.org/wiki/Concurrency_control] showing some often used methods.

thanks for the response, yes there are many columns that violate 3NF and that is why the column count is so high.
Regarding the partition question, by better I meant by using "interval" the partitions could be created automatically at the specified interval instead of having to create them manually.The key is to understand the logic behind these tables and columns. Why it was designed like this, if it's business requirement then 200 some columns are not bad, if it's design flaw 20 columns could be too much. It's not necessarily always good to have strict 3NF design, sometime for various reason you can denormalize the tables to get better performance.
As to partitioning Q, you have to do the rolling window (drop/add partition as time goes by) type of partitioning scheme manually so far.

IPC 4.0 Standalone with SQL 2005 Express as a database

Hello,
I am trying to setup IPC 4.0 standalone up for a training class on a XP laptop with SQL 2005 Express as the database. I keep getting login errors connecting the IPC admin.bat tool to the sql database. And yes, I know this is not 'officially' supported by SAP, but I see no technical reason why it shouldn't work and yes my port is correct. My entries are as such:
Alias: 00_230
Server: localhost
System: Microsoft SQL Server
Database Name: 00_230
port: 1433
User: ipc
password: hidden
client: 230
Is everything I entered correct? Am I missing anything that I need?
Thanks!

Hi Jeff.
You will probably have problems with the database subsystem, when you upgrade to UccX7.0.1 if the 3rd party database is af SQL2k5 server.
There is a fix for that problem, check below :
Upgrading UCCX to 7.0(1)Sr4 is failing ODBC connection to SQL 2005.
Symptom:
Upgrading the UCCX server to 7.0(1) Sr4 and OS to 2003.1.4a SR11 is failing the ODBC connection to SQL 2005 external database. (also a problem in new installations)
The error generated when trying to setup a ODBC connection to SQL 2005 database is
======
[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.
=======
Conditions:
Upgrade to UCCX 7.0(1) Sr3 or 4 and OS upgrade to 2003.1.4a SR11
Workaround:
Work around:
a) In UCCX SQL Server 2000 - Start the Client Network Utility. (cliconfg.exe is used from MSDE versions of UccX)
b) On the General tab, add TCP/IP in the list under Enabled protocols by order. (make sure its first)
c) Click the Alias tab, and then click Add. Under Network libraries, select TCP/IP.
d) In the Server name text box, type the IP address of the server that is running SQL Server
2005.
Note:
If port other that 1433 is being used Click the check box to clear the Dynamically determine port option, and then type the port number of the instance of SQL Server 2005 in the Port number text box.

Same sql query with multiple database links

Hi All,
i want to execute an sql query for a SELECT LIST Item. which should use database links in it's query.
i'm having a list of database links in the region. say :LOC which is having 10 items each linking to different databases.
i want to use following query for another item in same page.
select customer_name from working_lines@:LOC where
phone_no:phone_no
can i do this.
Thank you All.

What we have done before is to create a report based on a PL/SQL procedure that returns a SQL statement.
The PL/SQL code grabs the "selected" database link from :LOC and parses the SQL QUERY you want to execute replacing some token (like [LINK]) with '@DBNAME'.
Lets say your SQL statement is coded like this:
mySQL := 'SELECT cust_name FROM working_lines[LINK] where phone_no = :Phone;'
Then all you would have to do to replace '[LINK]' with the proper DB alias would be:
mySQL := REPLACE(mySQL, '[LINK]', '@'||:LOC);
and then return the new SQL ...
if :LOC has something like 'V10GPROD' your SQL would look like :
SELECT cust_name FROM working_lines@V10GPROD where phone_no = :Phone;
The beauty of this is that you can also include a "null" option that means the select statement will be executed on THIS database...

Architecture/Design Question with best practices ?

Architecture/Design Question with best practices ?
Should I have separate webserver, weblogic for application and for IAM ?
If yes than how this both will communicate, for example should I have webgate at both the server which will communicate each other?
Any reference which help in deciding how to design and if I have separate weblogic one for application and one for IAM than how session management will occur etc
How is general design happens in IAM Project ?
Help Appreciated.

The standard answer: it depends!
From a technical point of view, it sounds better to use the same "midleware infrastructure", BUT then the challenge is to find the lastest weblogic version that is certified by both the IAM applications and the enterprise applications. This will pull down the version of weblogic, since the IAM application stack is certified with older version of weblogic.
From a security point of view (access, availability): do you have the same security policy for the enterprise applications and the IAM applications (component of your security architecture)?
From a organisation point of view: who is the owner of weblogic, enterprise applications and IAM applications. In one of my customer, application and infrastructure/security are in to different departments. Having a common weblogic domain didn't feet in the organization.
My short answer would be: keep it separated, this will save you a lot of technical and political challenges.
