In Their Own Words: Kim Berg Hansen, 2015 Devvy Finalist, SQL and PL/SQL
 
22:43
Kim is a developer/architect using Oracle SQL and PL/SQL since 2000, specializing in doing it all in a single SQL statement wherever possible, utilizing the database to the maximum. He is an Oracle Certified Expert on SQL. In his work Kim utilizes SQL extensively to work with data, particularly using analytic functions and other SQL functionality to let the SQL engine perform the major part of any data analysis or manipulation. Then he wraps the SQL in PL/SQL to create business logic APIs, that can be reused whenever the app needs to be re-implemented in new UI frameworks. One example is the WheelGuide in his company's webshop (http://bit.ly/thgwheelguide). It is build around a PL/SQL API created 10 years ago. This site's UI was coded originally as a Java Applet, then some years later rebuilt in Adobe Flash, and more recently using HTML5.Throughout all of these changes, the PL/SQL API remained unchanged. Kim expands the capabilities of the company application by using PL/SQL to let the database work with data from the outside world by HTTP or FTP or Webservice calls. He also creates PL/SQL utility functions for use throughout the rest of the application, often combining SQL and PL/SQL and XML to integrate external data or do automated ETL. Kim has presented on SQL topics and his overall development paradigm at several conferences in the Oracle community, including ODTUG KScope and UKOUG's annual conference. He will present at DOAG in Germany in December 2015, and participate in the Optimizing PL/SQL for Performance and Maintainability panel discussion at Oracle OpenWorld 2015. Kim is also exploring, with Erik van Roon, the feasibility of setting up a Kscope-like conference in Europe ("EScope"). Kim is the main author of the weekly “Select from SQL” quiz on Oracle PL/SQL Challenge (http://plsqlchallenge.oracle.com); since May 2011 he has written over 178 SQL quizzes, which have been answered more than 60,000 times. He has authored several articles in OTech Magazine (http://www.otechmag.com). He blogs on Oracle development topics, mainly SQL (http://dspsd.blogspot.com). In his spare time Kim likes to cook, reads sci-fi, and is chairman of his local chapter of the Danish Beer Enthusiasts association.

Day 2 Wrap-Up | Oracle OpenWorld 2013
 
08:08
Open source plays a key role in IT innovation strategy this year and it's obvious from watching Oracle do its thing. In fact, Recent years have seen the emergence of a system in which the open source and free software are keeping innovation in IT world. This system takes root in some large web companies that do not consider their core system as the owner, but as technologies that they can share with others and pool. At the Oracle OpenWorld 2013 held from September 22 to 26 at the Moscone Center in San Francisco, CA, the company offered IT organizations with a one stop shop from heterogeneous collection of newer cloud-based solutions, middleware solutions and data sources to legacy applications for IT operational and business processes. For developers looking to automate some of these processes, Oracle provided tools such as Concurrent Manager and Process Scheduler for Oracle E-Business Suite (EBS) and PeopleSoft or PL/SQL scripts to automate Oracle database processes. Managing DB dependent development How do you manage development when development depends on underlying databases? Databases have no data control like source control for code. Because these development environments depend on databases and those databases are large and/or complex to build the build time can take anywhere between a few days to weeks. ManageEngine, which offers enterprise IT management solutions including network, server, desktop and application management, announced significant upgrades to the Oracle database monitoring feature in Applications Manager, its application performance monitoring solution. The latest upgrade improves tuning and troubleshooting of Oracle systems by enhancing real-time visibility into the health and performance of Oracle databases and their related applications. Whenever a business-critical Oracle application or process is underperforming, IT teams tend to point fingers at areas that are not well understood. Applications Manager monitors across the Oracle application stack — and any other heterogeneous set of servers, app servers and databases. The performance insight now offered by Applications Manager reveals exactly what's running and whether a problem is at the application, database or network level; so, you can solve performance problems faster and spend less time. Oracle 12c is capable of managing a set of guests or "pluggable databases" beneath its core system. Darryl Smith, Chief Database Architect for EMC IT, shared that Oracle databases allow database administrators to focus on getting in front of the business, understand what their problems are, so that IT can be more agile and responsive. He said once DBAs know about architecture and other aspects, automation can drive data protection-as-a-service (DPaaS) and DBAs can build automating the full application stack, backups, built in security, and a built-in DevOps model. He added DPaaS can literally set service levels for backup, set priorities, but to leverage DPaaS, DBAs need to be in control of both backup and recovery, and a tool such as DD Boost helps achieve that. More automation Most of the companies today operate in heterogeneous applications and platforms and are looking to more easy way to communicate across different platforms. Products from Oracle like Oracle EBS, PeopleSoft and JDEdwards have been designed for developers to more easily build and manage these cross-application and cross-platform batch processes. Beyond today's solutions, one of the goals of developers is to run job scheduler with technologies including Java, Web Services and Oracle Stored Procedures to allow it to hook into third-party applications. Oracle provides DBAs an enterprise automation solution to schedule a PL/SQL, Export or Import task once, but execute it multiple times across different Oracle DBs within a single interface.

Histograms Pre-12c and now
 
43:45
Anju Garg is an Oracle Ace Associate with over 12 years of experience in IT Industry in various roles. Since 2010, she has been involved in teaching and has trained more than a hundred DBAs from across the world in various core DBA technologies like RAC, Data guard, Performance Tuning, SQL statement tuning, Database Administration etc. She is a regular speaker at Sangam and OTNYathra.  She also writes articles for All Things Oracle. She is passionate about learning and has keen interest in RAC and Performance Tuning. She shares her knowledge via her technical blog at http://oracleinaction.com/ ABSTRACT--- To improve optimizer estimates in case of skewed data distribution , histograms can be created. Prior to 12c frequency and height balanced histograms could be created.  if no. of buckets >= NDV, frequency histogram is created and the optimizer makes correct estimates. If no. of buckets < NDV, height balanced histogram is created and accuracy of optimizer estimates depends on whether a key value is an endpoint or not. The problem of optimizer misestimates in case of height balanced histograms is resolved to a large extent in Oracle Database 12c by introducing top-frequency and hybrid histograms which are created if no. of buckets < NDV. This webinar explores Pre as well post 12c histograms while highlighting the top-frequency and hybrid histograms introduced in Oracle Database 12c.
Web Development Primer for PL/SQL Programmers - Introducing JavaScript
 
02:43
Now let's go on here. I mentioned that I'd show you how to debug JavaScript. Most of you PL/SQL programmers are very familiar with the concept of debugging from your experience with things like SQL developer and TOAD that will allow you to inspect your PL/SQL code and allow you to set break points and then single step through your code and inspect the individual values of your variables, kind of where your sins are in your code. Of course, JavaScripts, these tools have exactly the same concept. I'm sorry. I don't have to dwell on that too much. The trick here is A, you need to know that it does exist, which I'm just telling you now, and then you have to figure out where to find it. I've got a little example here so we can see it in action. A very simple theme - I could build a function called dividemembers. It just takes a numerator and a denominator, that's the division, and pops the result into a variable called vResult and then displays that on the page. Then you have some HTML down here and you can see up here that when I get the value of the numerator into the variable, there's a little piece of syntax. Here is it says, "Get element by ID," and of course the ID is a numerator and you can see I've got an input down here with this ID trick here so that the ID is numerator. That shows you how this ID business is used to tie the JavaScript to the HTML - very important concept here. And then we got two inputs, one for numerator and one for denominator. Here I actually put the result into a paragraph tag and it too has an ID of result. It's a paragraph on the page and we'll change this "And the answer is..." to whatever the result is from the division. Of course, to fire this function, we got a button to find. That button has an on-click event defined for it and that on click event happens to be the name of our JavaScript function. That's how the JavaScript function gets fired when we press the button.

Dynamic sql table name variable

This is one of the sql questions that is very commonly asked. I have a web page with a textbox. When I enter a table name in the textbox and when I click "Load Data" button, we want to retrieve data from that respective table and display it on the page. Copy the SQL Script to create the tables from my blog using the link below http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-table-name-variable.html Create the following stored procedure. Notice we are passing table name as a parameter to the stored prcoedure. In the body of the stored procedure we are concatenating strings to build our dynamic sql statement. In our previous videos we discussed that this open doors for SQL injection. Create procedure spDynamicTableName @TableName nvarchar(100) As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from ' + @TableName Execute sp_executesql @sql End So the obvious question that comes to our mind is, why are we not creating parameterised sql statement instead. The answers is we can't. SQL Server does not allow table names and column names to be passed as parameters. Notice in the example below, we are creating a parameterised query with @TabName as a parameter. When we execute the following code, the procedure gets created successfully. Create procedure spDynamicTableName1 @TableName nvarchar(100) As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from @TabName' Execute sp_executesql @sql, N'@TabName nvarchar(100)', @TabName = @TableName End But when we try to execute it we get an error - Must declare the table variable "@TabName" Execute spDynamicTableName1 N'Countries' Add a Web Page to the project that we have been working with in our previous video. Name it "DynamicTableName.aspx". Copy and paste the HTML from my blog using the link below http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-table-name-variable.html Copy and paste the code from my blog in the code-behind page http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-table-name-variable.html At this point, run the application and type the following text in the "Table Name" textbox and click "Load Data" button. Notice "SalesDB" database is dropped. Our application is prone to SQL injection as we have implemented dynamic sql in our stored procedure by concatenating strings instead of using parameters. Employees; Drop database SalesDB One way to prevent SQL injection in this case is by using SQL Server built-in function - QUOTENAME(). We will discuss QUOTENAME() function in detail in our next video. For now understand that by default, this function wraps that string that is passed to it in a pair of brackets. SELECT QUOTENAME('Employees') returns [Employees] Modify the stored procedure to use QUOTENAME() function as shown below. Alter procedure spDynamicTableName @TableName nvarchar(100) As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from ' + QUOTENAME(@TableName) Execute sp_executesql @sql End At this point, type the following text in the "Table Name" textbox and click "Load Data" button. Notice you will see a message - Invalid object name 'Employees; Drop database SalesDB'. Also "SalesDB" database is not dropped. Employees; Drop database SalesDB The entire text in "Table Name" textbox is wrapped in a pair of brackets by the QUOTENAME function and is treated as table name. Since we do have a table with the specified name, we get the error - Invalid object name.
