Analytical Functions in oracle explained with real examples
This video explains analytical functions and how they are implemented in real projects. Analytical functions are somewhat similar to aggregate functions,but they offer much more. Why use analytical function ? They allow you to write fast and concise queries which otherwise will involve self join and long processing times They allow you to perform aggregate functions independently on sets of partitions. You can access values from previous rows in current row and you can restrict the window on which you want to apply this analytical function. I have given additional practice exercises along with the dataset so that you can comfortably work with analytical functions. You can find the sample problems along with dataset in the below link. http://www.internshipsfromhome.com/oracle-analytical-functions-ddl-and-dml/

Part 1   How to find nth highest salary in sql
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/05/part-1-how-to-find-nth-highest-salary_17.html This is a very common SQL Server Interview Question. There are several ways of finding the nth highest salary. By the end of this video, we will be able to answer all the following questions as well. How to find nth highest salary in SQL Server using a Sub-Query How to find nth highest salary in SQL Server using a CTE How to find the 2nd, 3rd or 15th highest salary Let's use the following Employees table for this demo Use the following script to create Employees table Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) GO To find the highest salary it is straight forward. We can simply use the Max() function as shown below. Select Max(Salary) from Employees To get the second highest salary use a sub query along with Max() function as shown below. Select Max(Salary) from Employees where Salary [ (Select Max(Salary) from Employees) To find nth highest salary using Sub-Query SELECT TOP 1 SALARY FROM ( SELECT DISTINCT TOP N SALARY FROM EMPLOYEES ORDER BY SALARY DESC ) RESULT ORDER BY SALARY To find nth highest salary using CTE WITH RESULT AS ( SELECT SALARY, DENSE_RANK() OVER (ORDER BY SALARY DESC) AS DENSERANK FROM EMPLOYEES ) SELECT TOP 1 SALARY FROM RESULT WHERE DENSERANK = N To find 2nd highest salary we can use any of the above queries. Simple replace N with 2. Similarly, to find 3rd highest salary, simple replace N with 3. Please Note: On many of the websites, you may have seen that, the following query can be used to get the nth highest salary. The below query will only work if there are no duplicates. WITH RESULT AS ( SELECT SALARY, ROW_NUMBER() OVER (ORDER BY SALARY DESC) AS ROWNUMBER FROM EMPLOYEES ) SELECT SALARY FROM RESULT WHERE ROWNUMBER = 3

Entity Relationship Diagram (ERD) Tutorial - Part 1
Learn how to create an Entity Relationship Diagram in this tutorial. We provide a basic overview of ERDs and then gives step-by-step training on how to make an ER diagram with correct cardinality. Entity Relationship Diagrams are comprised of 3 main categories: entities, attributes, and relationships. Entities are objects or concepts that are associated with important data—like a customer, order, or product. Attributes represent properties or traits of an entity, such as a customer’s phone number or home address. Relationships demonstrate the link between entities. Another main aspect of of ERD's is cardinality, which further defines the relationship between entities in a numerical way. Certain symbols signify the minimum and maximum relationship between different entities.

Easiest Way to Learn Oracle
What is the easiest way to learn Oracle? I get why you’re asking the question – it isn’t like you can just install Oracle on your personal computer and learn from it like the PHP or Python IDE. And there are licensing fees, I’ve heard, for using it. But Oracle is way more complicated than something I want to learn from an Oracle for dingbats book. You’re right, no one will hire a DBA whose skill sets come from having read the whole series of books but never logged into the database much less run an activity log. So how do I learn Oracle? Udemy has some decent classes. Udemy costs money. Oracle’s home page has links to tutorials on how to use its tools. Most of the tutorials are really specific like installing Oracle 10G on Windows, installing 11G on Linux, or how to debug the database with SQL developer. That’s more than I knew before. The advantage of the site is having correct answers to specific but common issues like how to use the performance tools or how to import and export large orders. You act like there’s a catch. The disadvantage is that it doesn’t have the really simple stuff beyond installing the database. So where can I get those basics? I’m sure Oracle has the resources. Sure, and they charge as much as you’d expect for a college for training on how to install and upgrade databases through an online class or in person workshop. Where can I find free resources? SkillBuilders dot com has some free tutorials on Oracle, like advice on how to clone a database, an understanding of new functions with each Oracle version and basic tuning tips to improve system performance. None of them are an in depth course on getting started, and all of them are partial commercials for the costly classes. Anything is better than nothing, especially if it costs nothing. I might recommend the MIT OpenCourseware urban studies and planning courses. I’m asking about IT, not architecture. For example, the Spatial Database Management and Advanced Geographic Information System class teaches you how to connect Microsoft Access to an Oracle database and create complex queries. That’s advanced user stuff, not administration stuff. So try Excel4apps dot com. They have demos for using some of the Oracle reporting interface tools. Next option is Youtube. That doesn’t strike me as an advanced fount of IT wisdom, except to demonstrate video game tricks and accomplishments on WoW. The Oracle Learning Library has short demos on how to import data from Excel into Oracle and other administrative tips. So borrow the books if you’re on a budget or attend the classes if you can afford it.

How To Kill All Database Processes On SQL Server
SQl management studio provides lot of facilities to manage SQL processes. The “Activity monitor screen” which will show you some very useful and important information about SQL processes. It will show you all active processes, there status, number of open transactions for each process, the application by which the process is generated, Wait time CPU and memory utilisation, and the host name, means the host or the machine by which the process is initiated etc. If a process is hanging, it will show the process icon with an hour glass. Refresh it several times, sometimes the icon will turn to sleep mode if the process completes its execution. If the icon remains an hour glass, the process may be hanging. Use other info as well to decide if the process is really hanging. If you double click on the process ID it will show the SQL stamen subjected to the execution of the process. If a process is hanging you can identify which application has originated the process, which SQL stamen is hanging and even more from which machine or the host the process is initiated If some application users are complaining about uneven slowness, uneven timeouts etcetera, the reason behind may be one or more processors are hanging. What can you do now? You can restart the SQL server or the service which will disconnect all databases and all applications disturbing all the users. Or otherwise you can take the database to off line and bring it back to online. Or you can disconnect all connections to the database. The disturbance may be lesser than the previous case but still lot of applications and users can be disturbed, especially in an industrial setup. And still you do not know the real reason for the slowness or the malfunctioning as well. So what can you do? Go and examine the processors. Identify exactly which process is hanging. And most probably you will be identifying how and why. So you can find permanent solution. But the immediate solution is you can kill the troubling process or the few. It will solve the issue with minimum disturbance immediately. After identifying the correct process, you can right click on the process ID and click on ‘Kill process’ button. It will kill the selected process. You can kill processors using SQL statements and, using SQL commands you can kill all processors at once as well. Code for Killing Processes Individually USE master go DECLARE @dbname sysname SET @dbname = 'YourDB' EXECUTE ('KILL 53') Code for killing all Processes USE master go DECLARE @dbname sysname SET @dbname = 'YourDB' DECLARE @spid int SELECT @spid = min(spid) from master.dbo.sysprocesses where dbid = db_id(@dbname) WHILE @spid IS NOT NULL BEGIN EXECUTE ('KILL ' + @spid) SELECT @spid = min(spid) from master.dbo.sysprocesses where dbid = db_id(@dbname) AND spid @spid END

CalculatorDemo - Oracle SOA 12c Examples ------------------------------------------------------------------------- Steps: ======= 01. Open JDeveloper 12c 02. Create SOA Application called "SOA_POCs" and then create an SOA Project called "Calculator_Demo" 03. Create Custom XSD with required fields and valid filename (Naming convention). XSD got ready. 04. Create Synchronous BPEL 2.0 Process. In 12c by default BPEL 2.0 selected. 05. Goto Composite.xml and drag n drop BPEL component on Components canvas. 06. On 'Create BPEL Process' wizard, select Template as 'Synchronous BPEL Process' and also select the Request & Response for input & output. 07. Double click on BPEL process and it redirected to BPEL process editor. 08. Drag n Drop 'If' condition in between 'receiveInput' & 'replyOutput' activity. 09. Always Select Expression language as XPATH 1.0 in BPEL 2.0 10. Completed the Flow, now compile the code, once successfully completed then deploy the code on SOA Application Server. 11. I have already started the local Admin & Application server. 12. Deploy the code. In JDeveloper, I have already configured the server named "conn_weblogic12c" 13. Deployed the code on SOA Application Server. 14. Go to EM Console (http://localhost:7001/em) and check the code got deployed successfully or not. 15. Test the composite in SOAP UI Tool. 16. Open SOAP UI Tool or you can test through em console but that is not good practices. 17. Copy Endpoint URI with '?WSDL' and import in SOAP UI Tool. Before this, first, check it in the browser. Perfectly working. 18. All conditions are successfully executing. 19. When % (Modulation) as operation name then it throws Business Fault i.e., "Please enter correct operation name and try agin..".

SQL:Max/Min Functions
In this tutorial, you'll learn how to use max min functions in sql queries. PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

Difference Between Delete and Truncate
Below is link for Useful Pl/SQL Books http://goo.gl/XMy0tt ---------------------------------------------------------- Difference Between Delete and Truncate in Detail On bigger picture they serve the same purpose but there are many Differences listed with examples Point Delete Truncate 1. Data Recovery Delete: Come under the DML Category, we need to commit or Rollback explicitly to make the changes permanent, so we can recover the data by Rollback command fully with in a session or up to a point if Save Points are used Fall In DDL Category (DDL Command issue the Auto commit implicitly) so no chances of Recovery even not using the Flashback table method. But Truncate operations are also logged , they didn’t generate redo SQL but they are logged , view for truncated data info V$LOGMNR_CONTENTS 2. Data Removal Delete Can remove all or selected data using the Where Clause predicates. Or we can say delete any subset of rows We can Truncate complete table or a partition or sub partition of a table. 3. Speed Delete is Slower because oracle maintain the redo logs for Read Consistency (so that every session connected can see a consistent data at a given point of time ) Delete is very time consuming activity especially when table have numerous indexes and Triggers associated with table Faster as no data logs are maintained no associated trigger firing. 4. DML Triggers Firing DML (Delete) triggers associated with table will fire. DML Trigger will not fire in case of truncate method. 5. Flashback Technology Data can be recovered even after commit operation using Flashback Table options Flashback_transaction_query table will give what to recover and up to which point. Data cannot be recovered in truncate method by Flashback table option. 6. Referential Integrity Constraint Behavior if we don’t have related data in child table then we can delete the data from the parent table or we have variants like On Delete Cascade & on Delete set Null. We can’t truncate a table with enable Referential Integrity Constraint, even there is no data in the child table, we have to disable or drop the constraint if we want to truncate the table. Exception: Truncate is possible if the FK is self-referential means primary key and foreign key are on the same table. 7. Space De allocation or Space Utilization No extent reset with delete when deleting rows from a table, extents are not de allocated, So if there were 50 extents in the table before the deletion, there will still be 50 after the deletion. Truncate: When a table is truncated it will free the space allocated except in case of reuse storage clause. This space can subsequently be used only by new data in the table or cluster resulting from insert or update operations .All extents are de allocated leaving only the extents specified when the table was originally created .Example So if the table was originally created with min extents 3, there will be 3 extents remaining when the tables is truncated. When you truncate a table, NEXT is automatically reset to the last extent deleted. 8. High Water Mark Delete will not reset the high water mark Truncate will reset the High Water mark which is very important for performance point of view as in case of full table scan and full index scan oracle will read all the block under high water mark this makes a lot of difference in terms of performance. 9. Cluster No as such restriction with delete. You cannot individually truncate a table that is part of a cluster. You must truncate the cluster, Delete all rows from the table, or drop and re-create the table. 10. Information Capturing Delete : we can capture the row information what we have deleted using Delete Method, f you are deleting multiple records then use composite data types (collections & records) Truncate Don’t have this feature of capturing the deleted records. 11. Function Based Index Impact DELETE You cannot delete rows from a table if a function-based index on the table has become invalid. You must first validate the function-based index. Truncate: No as such restriction 12. UNUSABLE Indexes Delete no as such feature. Truncate if table is not empty then truncate make all unusable indexes to useable. 13. Complex views You cannot delete data from a Complex view except through INSTEAD OF triggers. But we can delete data from simple Views and MV. We cannot truncate a view simple or complex but you can truncate MV with special Features like Preserve MV Logs and Purge MV Logs. 14. Privileges Delete You need to provide delete table privilege on object. Truncate you must have drop table privilege there is no truncate table privilege exists. 15. Domain Index No as such restriction You cannot truncate the object having domain index in invalid or In progress state

Sam Lucido | Oracle OpenWorld 2013
Sam Lucido, Technical Marketing Lead For Oracle, EMC, discussed the Oracle-EMC partnership and the day's keynote with theCUBE co-hosts John Furrier and Dave Vellante, live from Oracle OpenWorld 2013. Regarding the Day 2 OpenWorld keynote, "EMC recognizes that we need to enable DBAs and app owners," Lucido said. There is an open infrastructure strategy where EMC applies to everything. With the new range of plugins, the Oracle Database can now look into the storage and see, for example, whether storage admins apply flash cache to their infrastructure, he explains. Discussing the statistics that reveal how database administrators spend their time, Lucido said the top activity was performance tuning for Oracle databases, followed by patching work and maintenance. "As a DBA you always get to patch the database," be it security patches or performance, Lucido said. "You can't modify that SQL yourself. When you come up with a converged architecture," the DBA is responsible for more -- patching everything in the converged infrastructure. "Oracle has done some great things with performance, but most customers can run a certain version, so a system where you can run several versions and maintain performance, that's absolutely fantastic." With the release with our EMC XtremSF cards, they can be plugged into the storage and have in-server memory. "As soon as you put those cards into the server, you get microseconds response time," which works with all possible versions, "that's how we're competing." Exploring the Oracle-EMC partnership Exploring the Oracle-EMC collaboration, Lucido said VPLEX was a great story between the two companies, which enables taking the Oracle rack and extending it over multiple sites. "The capability to have the cluster stretch over 100 kilometers" is one of the common projects. "At EMC, we're really adding people to our Oracle alliance team. We'll add more integration like that." Asked what he found exciting about the new Oracle Database 12C, Lucido said, "I think 12C is actually clever with virtualization." DBAs can move container databases from one site to another, but it was a manual process. People will consider virtualization in 12C because they will have to move all their constant databases and program databases at once. "Oracle does security very well," Lucido said. "Most databases I know of, there is rarely any problem with break ins. We add value, we can secure their virtual machine. If you move it, our security will follow, so you can have security no matter what you do with the database." Asked to comment on the NoSQL movement, Lucido stated "NoSQL is a very strong trend and I only see it gaining market share. NoSQL databases are a fantastic trend to back. We do have a big group at EMC dedicated to that, EMC definitely embraces the NoSQL trend." Sam Lucido, EMC, at Oracle OpenWorld 2013 with John Furrier and Dave Vellante @thecube #oow13

How an intense and diverse SQL statement workload can cause Oracle parsing problems
Make your library cache angry! This video is about how an intense and diverse SQL statement workload can cause Oracle parsing problems. There are many reasons for Oracle parsing related performance issues and many ways to identify them. So, I am narrowing the scope by focusing on one possible cause, that is, an intense and diverse SQL statement workload. I will use Oracle's wait interface to identify the root cause. Sound dry and boring? To make this a little more interesting and a whole lot more fun, I'm going to approach this from a non-traditional, almost backward perspective. After explaining some of the Oracle internals, I'm going to create a parsing intensive workload and then watch what happens... in real time. The educational impact is so powerful, I recorded a video This is video is part of Craig's blog post: http://blog.orapub.com/20170126/how-an-intense-and-diverse-sql-workload-causes-oracle-parsing-problems.html For more information go to www.orapub.com
