Oracle Pl/Sql and Oracle Application Express for Beginners

Good day,
Have a prodigy that is strongly interested in oracle application express.Haven know that he will only do we in APEX if he is good in pl/sql and have some skills in html and javascripts.
For such person,what are the books that i can recommend for him,that will guide and assist him?Will be highly grateful if anybody can assist.

I think it also falsely gives the impression that one does not need to understand the database at all because Apex can do everything for you...This is why I echo Munky when he says that you need a solid understanding of data models and the database before attempting to build an application.
I absolutely concur with this view. When I first started using ApEx, I was basically given a user guide and told to get on with it :-) Subsequently, for the first 6 months or so, I built probably fairly lousy (but functional) apps until I got a better grasp of Oracle architecture.
That being said, SQL is an absolute must if you are going to work on a database. PL/SQL really should be learned as well because your application will be limited without it. CSS and Javascript and nice to have's, but they can be learned as you go. Since all of the api's are built in pl/sql, it would really hinder what you could do if you didn't know it.One resource I have found very useful is the good old 'Ant' book a.k.a. Oracle PL/SQL Programming by Feuerstein, et al. I have a well-thumbed 4th edition sitting on my desk at the moment - weirdly for a text book, rather a joy to read.
I personally found Jay-Lew's "Cost-based Oracle Fundamentals" a somewhat bitterer pill to swallow - tough on the way down but good for one's constitution!

Uses for the Action Property with SQL and Oracle DB Adapters

This thread is a complement to the Wiki Article
BizTalk: Streamlining WCF SQL and Oracle Messaging-Only and Other Patterns
The question. In what circumstances is explicitly setting the Action value with the WCF SQL and Oracle DB bindings useful or beneficial.
A complimentary question. Is it even possible to set the Action value to anything other than exactly what is required by the Message.
I ask because of three very specific behaviors of the bindings themselves:
The binding enforces a match between the Action and the Message, therefore...
There is a one-to-one relationship between the Message and Action, but...
The binding is able to correctly derive and perform the requested operation with the unspecific CompositeOperation.
For clarity, I understand how to set the Action. I. understand what the Action represents in the SOAP scheme. I understand how Action can be used as an abstraction for SOAP operations.
Thoughts?

Do you have any good suggestion to learn how to use action property with SQL and Oracle DB adapters? I learn a lot from your replies for years in BizTalk forum. :)

Need a function name for Sql and Oracle

Retrieving value of next line by doing opteration in previous row.

Can you rephrase the question? Or better yet, provide an example? I'm not sure I understand what you are asking.
My best guess is that you are looking for the analytic functions LEAD or LAG in Oracle, assuming you are on a relatively recent Oracle version. If by "SQL and Oracle" in your subject you mean "SQL Server and Oracle" (SQL is a language that all relational databases implement, SQL Server is Microsoft's relational database), I have no idea how (or if) you can do something similar with a built-in function in SQL Server. You would want to post in a SQL Server group to see how they handle that sort of thing.

Tablespace size report for SQL and oracle servers

Hi All
is it possible to get tablespace size for all sql and oracle server in the form of report in SCOM.
Regards
Madhavi

Oracle: Table size report of Oracle is depend on the MP which yu imported into SCOM
SQL :
1) Create a group which contains folowing dynamic rule
2) Reporting workspace --> Microsoft Gneric Report --> Performace Detail
3) in the parameter area, create a new series, add group which create in step 1) and select the rule: MSSQL XXX: Collect Database Allocated Size(MB)
4) Run the report
5) In the report, click actions and select "Performance details for every object"

Frequently transfering databases between MS SQL and Oracle

Hello all,
I am looking for a solution to easily, efficiently and be able to migrate/transfer databases between MS SQL and Oracle frequently.
I need to be able to replicate a databases on Ms SQL and Oracle for testing purposes. I will need to do this on frequent basis - almost once a week.
Please suggest what would be the best way.
Thanks in advance.

Hi Justin,
You have guessed it right to a great extend. Yes dont actually need to develop, rather need to test an application that supports SQL and Oracle databases. Now when testing the application its obviously vital to create proper systematic test data. This usually takes a lot of time and effort from the testing team/team-member. So, yes what I need to do is create the test data on one database(may it be SQL or Oracle) and migrate/transfer the data into the database on another server( ie. SQL to Oracle or Oracle to SQL).
So,
Are you developing a product that works against both SQL Server and Oracle and trying to synchonize development efforts?Yes, thats correct to extend, I need to test an application against both the servers, as it supports both types of databases, and try to reduce the test setup efforts (literally double the amount) that go in after manual creating same data on each type of database.
Are you trying to replicate structural changes between systems?I am not 100% sure, what you mean by this. But whats important and enough for me is to replicate the data. It would not be a lot of work to run the scripts and create empty schema objects.
Are you trying to replicate data changes between systems? The fact that you're only doing this weekly suggests that you're not working in a traditional replication environment.Yes, again as I mentioned above. It would be sufficient for me to just get a copy of the initial dataset. And then replicating changes to it would not be that important. However, if I can achieve a solution to this, I can by all means create a new database on the one server (SQL or Oracle) and take the data-set of the most recent/correct changes and replicate it on the other type of server as and when needed.
No - this is not a traditional replicating environment. I say weekly, because it is usually once in a week or forthnight that someone from the team will need to spent time to manually copy the test-data onto the another type of server in order to run the same testcases on two types of servers.
How do you handle conflicts (i.e. if I modify a row in both systems, which modification wins)? This is not really a problem in my scenario, as I only need to be able to transfer the data across to the different server and forget about the two databases actually being in-sync.
I have also, looked at DTS for a possible solution on SQL, however it seems highly un-realistic, having to map somewhere like 250 tables from the a drop-down list, only because the two database servers use different cases to represent tables internals. So, table 'Table' in my application's SQL database is called 'TABLE' is my applications Oracle database. DTS is highly inefficient in dealing with this. Also, having 250 tables move makes this a bit of a pain.
Thank you Justin for your response; I highly appreciate your inputs.

Coneection between Oracle to SQL and SQL to Oracle

Dear All,
I have oracle 11g R2 (32 bit) on windows 32 bit.
I have sql express edition 2008 (32 bit) on windows 32 bit.
More information about my system is :-
I have install oracle database and sql database on same machine (there is no client).
I want to fetch data from oracle to sql and sql to oracel. I have tried Using ODAC 32 bit but with no luck.
steps i have performed:-
1) Install odac for windows for oracle 11g R2 version (successful).
2) Tried to create odbc connection using odbc driver (successful).
3) Tried to create link server in sql (successful).
4) Tried to connect to oracle using link server (failed).
It seems i made some small mistake.
I request you to please help me if you have perform this activity.
Thanks,

Oracle Database 11g Administrator or Oracle PL/SQL and Forms Developer?

Hi,
I am thinking about doing an Oracle certification course- Oracle Database 11g Administrator or Oracle PL/SQL and Forms Developer.
Oracle Database 11g OCP and OCM certification requires 3 mandatory training courses to be completed that costs between $1900 and $3250/each. Oracle PL/SQL certication doesn't require any mandatory training course.
Which one of these would be a good choice? Please advise.
Thank you,
Tracy

Regardless of which path you want to take, in order to get the OCP certification in either the DBA or PL/SQL developer track, you must first obtain the respective OCA certification for that track. I'm assuming that since you are still undecided in which path to take that you haven't started working on either yet. If you look at the pages for the OCA DBA and OCA PL/SQL Developer certs and what is required for each, you'll see that the first block of tests for either certification (the SQL based exams) has the same options (1Z0-007, 1Z0-047, 1Z0-051) and passing one of those SQL based exams gives credit towards obtaining both OCA certifications. That might be a good place to start.
Doing one of these tests first might give you some extra time to decide which track you want to pursue. But as Justin said, it really depends on what you do (or plan on doing) in your career as to which path might be more beneficial for you.
As for the OCM level stuff, I wouldn't even think about it until you get the OCP. One step at a time... Same with OCP before OCA. That being said, my suggestions are just that, suggestions. You're free to take any exams/courses in any order, but you won't be able to obtain the certs until you have completed the requirements for each.

Run Oracle Web Logic and Oracle Application Server 10g on same server

Since oracle has chosen to release adf faces 11g, before the SOA suite 11g is released, we are facing the challenge to run both Oracle Web logic and Oracle Application Server 10g on the same server.
If anyone have any experience in this setup or has knowledge of other feasable setups please let me know.
Regards.
Jan

What version of Oracle Application Server 10g are you installing?
If you are installing 10gR2 (v10.1.2.x) have you taken a look at point #70 in "Table 2 Additional Information for Certified Platforms" section here?

Can We use FDM as ETL tool between SQL and Oracle

I want to use FDM as ETL tool between SQL and Oracle. Can it be possible. I didn,t found any target adapter for oracle database.My source system is SQL and Target system is Oracle database.
Rahul
Edited by: user12190125 on Nov 9, 2009 4:23 AM

Rahul,
I believe this is possible to do, but not an easy one and there are a few considerations:
How much data are you processing? FDM has a lot of features which support the business process. While this is great for users and audit trail etc. it slows down performance if you want to process a lot of data. It also depends on the type of mappings you use (Like mappings are slower than explicit mappings).
How familiar are you with VBScript? There is no explicit target adapter for Oracle, but there is a data mart adapter which can be used for anything. You have to implement everything yourself though, mainly the Export and Load actions. In there you will also have to handle the the connections to the MSSQL and Oracle databases.
Check the data mart adapter and see if you feel comfortable with defining the vb code in there. There are reasons for and against this approach. ODI would probably be the better choice unless you really need to have FDM's process support.

Matt

SQL and Oracle in synchronization

I have to synchronize for about 2 months one Oracle 9.i database and one SQL server 2000, Standard edition database, both running on Win 2K Server. Every change made on either of the databases (the best is there are only 4-5 tables reflected) has to be provided on the other side almost in real time. I choused to use SQL server as a way to do it. For Oracle I have only the ODBC connectivity (supplied for free) and I did have a lot of problems in ORA 8.1.6... Needless to say, there's no money for third party products or even new ORA transfer utility, as the 2-month are not sufficient time.
I did set up linked servers between SQL server and Oracle and trying to make some triggers working for me, but is this the best way to do it? May be somebody has better experience...
Any ideas will be greatly appreciated.
Thanks,
MJ

Do you really like to implement a two way replication between M$ SQL and Oracle?
Maybe you can try this using the heterogenous gateway and Oracle Advanced replication. Don't know if this could work our test environment would be ready but actually there's no time to try.
Will keep you informed if I know more.
In this way you don't need any third party sw and I think it could work, but never have tried it out.
Could be an interesing challenge ;-)

What is Difference between ANSI SQL and ORACLE SQL

Hi,
I am going to take the assesment test for ANSI SQL Programming before that i want to know any difference between ANSI SQL and ORACLE SQL?
I am studying for SQL but the test will be ANSI SQL please let me give an idea about the both.
Thanks
Merina Roslin

Basically there is syntax difference between both of them.
Lets say i want to join two table EMP and DEPT based on DEPTNO.
With Oracle SQL format its like this.
select e.*
from emp e, dept d
where e.deptno = d.deptnoHere the joining condition goes in the WHERE clause.
With ANSI SQL format its like this.
select e.*
from emp e
join dept d
on e.deptno = d.deptnoHere the join condition is mentioned separately and not in WHERE clause.
Oracle supports ANSI SQL starting from 9i version.
You can read more about the syntax difference Here

About SQL and Oracle

Hello, I was using a MySQL database and i will soon use Oracle8. I was wandering if Oracle authorize something like mysql_result... I'm looking too for simple documentation about connecting to an Oracle database from a php file using Sql. Do u know books or sites ? Tks

Does Oracle support T-SQL ? Why would Oracle support a proprietary macro-based language implementation from a competitor?
If it is not supported in Oracle, what is the major grammer difference between T-SQL and Oracle supported SQL ? Oracle has two languages. SQL. PL/SQL.
PL/SQL is formal declarative procedural language with object orientation programming features. It is based on the Ada language (close relative of the Pascal language).
SQL is fully integrated with PL/SQL. Which means that you can write and mix SQL source code with PL/SQL source code and the PL/SQL compiler will figure out which is which and where to make calls to the SQL engine for executing SQL code.
Is there any efficient way for programmer to complete T-SQL transition to Oracle SQL ? Yes. Unfortunately not the answer that you are likely hoping for.
Forget EVERYTHING you did with T-SQL.
There is no real comparison between the two. And not only many differences, but some fundamental and conceptual differences too.

What difference between Oracle 9i AS and orion application server?

Hi:
Today I visited some website and read an information that Oracle 9i AS and orion application server are two differece application server.But When I start Oracle 9i AS ,I must use command of "java -jar orion.jar".Are they the same application server? If not ,can you tell me what difference?
Thanks

Hi Liu,
I'm sure other people will coreect any errors I am about to make
(if I make any :-), but some time ago, Oracle mad a licensing
agreement with a company called IronFlare, regarding IronFlare's
application server product called OrionServer. After that, Oracle
came out with a new product -- Oracle Containers for Java (OC4J)
-- which is based on OrionServer. In the first version (that had
the version number 1.0.2.2), the application server basically came
bundled in the "orion.jar" file, so in order to start up the application
server, you used a command like:
java -jar orion.jar
However, the next version of OC4J (with version number 9.0.2.0.0
[go figure ;-]), contained the "oc4j.jar" file (which replaced
the "orion.jar" file).
So I would say that the first version of OC4J was almost identical
to OrionServer. But I think subsequent versions are becoming more
and more different. Remember that at the same time, OrionServer
is also still being developed. I think the first version of OC4J
was based on version 1.5.2 of OrionServer. The next version of
OrionServer (that should be released soon) is version 1.6.0.
I have no idea how similar the latest version of OrionServer is
to the latest version of OC4J. But if Oracle's history is any
guide, then I would say that, eventually, OC4J and OrionServer
will have very little similarity between them. Just look at the
paths that Oracle's JDeveloper has taken in comparison with Borland's
JBuilder. Originally, JDeveloper was based on JBuilder. Today,
they are two completely different products.
Hope this has helped you.
Good Luck,
Avi.

Oracle version of the Microsoft Application Blocks for Data Access

Where can I find an Oracle version of the Microsoft Application Blocks for Data Access? Is it tied to any specific version of the Oracle Client software? I currently have version 8.1.7.3 installed.

I think that DAAB 3.0 only has support for ODBC and OLEDB, which indeed can be used for Oracle. The Nile 3.0 program has an OracleHelper file, but this one uses the Microsoft Dataprovider for Oracle RDBMS. With some minor changes you can make this version work with the ODP.NET that Oracle provides.
The issue I'm trying to convey is, that it seems hard to use the Microsoft Application Blocks using ODP.NET. As I described earlier, the LOBs and REF Cursors are reference types that actually point to data in the Database. This means, that the Connection to the database must be open to get to the Data.
In the DataHelper, you open the Connection and get the data you need. The DataHelper should then clean up and close the Connection. Then you pass the data to the caller. However, since we're dealing with Reference types, a closed connection means no data.
So I guess the only way to make this easy to use and not having to assume the caller/developer will open and close connections, you must copy the data in an instance of a DataSet, before you close the connection and then pass the Dataset back to the caller.
I wonder if people have delt with this issue and what their solution looks like.
thnx
