SQL: WITH Clause
 
06:11
In this tutorial, you'll learn will learn how to use with clause 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.

Analytical Functions in oracle explained with real examples
 
25:24
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/

DECODE Function ( IF..THEN..ELSE) in SQL ORACLE Query With Example
 
05:35
ORACLE/PLSQL: DECODE FUNCTION The Oracle/PLSQL DECODE function has the functionality of an IF-THEN-ELSE statement. The syntax for the Oracle/PLSQL DECODE function is: DECODE( expression , search , result [, search , result]... [, default] ) ARGUMENTS: expression is the value to compare. search is the value that is compared against expression. result is the value returned, if expression is equal to search. default is optional. If no matches are found, the DECODE function will return default. If default is omitted, then the DECODE function will return null (if no matches are found). Lets apply this function on emp table. Emp table has 3 dept numbers like 10,20 and 30. So if I want to display the different dept names based on ID, I have to use IF THEN ELSE condition. IF deptno=10 THEN "DEPT1" ELSE deptno=20 THEN "DEPT2" ELSE deptno=30 THEN "DEPT3" This entire IF block can be achived using single DECODE(). DECODE(deptno,10,'DEPT1',20,'DEPT2',30,'DEPT3') Query used in Video: select empno,ename,deptno,DECODE(deptno,10,'DEPT1',20,'DEPT2',30,'DEPT3') from emp;

CASE Function( IF..THEN..ELSE) in SQL ORACLE Query With Example
 
04:03
ORACLE/PLSQL: CASE STATEMENT The Oracle/PLSQL CASE statement has the functionality of an IF-THEN-ELSE statement. Starting in Oracle 9i, you can use the CASE statement within a SQL statement. The syntax for the Oracle/PLSQL CASE statement is: CASE [ expression ] WHEN condition_1 THEN result_1 WHEN condition_2 THEN result_2 ... WHEN condition_n THEN result_n ELSE result END --------- ARGUMENTS: expression is optional. It is the value that you are comparing to the list of conditions. (ie: condition_1, condition_2, ... condition_n) condition_1 to condition_n must all be the same datatype. Conditions are evaluated in the order listed. Once a condition is found to be true, the CASE statement will return the result and not evaluate the conditions any further. result_1 to result_n must all be the same datatype. This is the value returned once a condition is found to be true. NOTE: If no condition is found to be true, then the CASE statement will return the value in the ELSE clause. If the ELSE clause is omitted and no condition is found to be true, then the CASE statement will return NULL. You can have up to 255 comparisons in a CASE statement. Each WHEN ... THEN clause is considered 2 comparisons. Lets apply this function on emp table. Emp table has 3 dept numbers like 10,20 and 30. So if I want to display the different dept names based on ID, I have to use IF THEN ELSE condition. IF deptno=10 THEN "DEPT1" ELSE deptno=20 THEN "DEPT2" ELSE deptno=30 THEN "DEPT3" This entire IF block can be achived using CASE. CASE deptno WHEN 10 THEN 'DEPT1' WHEN 20 THEN 'DEPT2' WHEN 30 THEN 'DEPT3' ELSE 'NO DEPT' END; Query used in Video: select empno,ename,deptno,CASE deptno WHEN 10 THEN 'DEPT1' WHEN 20 THEN 'DEPT2' WHEN 30 THEN 'DEPT3' ELSE 'No Dept' END from emp;

COALESCE Function in SQL ORACLE Query With Example
 
03:53
ORACLE/PLSQL: COALESCE FUNCTION The Oracle/PLSQL COALESCE function returns the first non-null expression in the list. If all expressions evaluate to null, then the COALESCE function will return null. The syntax for the Oracle/PLSQL COALESCE function is: coalesce( expr1, expr2, ... expr_n ) PARAMETERS: expr1 to expr_n are the expressions to test for non-null values. EXAMPLE: The COALESCE function can be used in Oracle/PLSQL. You could use the coalesce function in a SQL statement as follows: SELECT COALESCE( address1, address2, address3 ) result FROM suppliers; The above COALESCE function is equivalent to the following IF-THEN-ELSE statement: IF address1 is not null THEN result := address1; ELSIF address2 is not null THEN result := address2; ELSIF address3 is not null THEN result := address3; ELSE result := null; END IF; The COALESCE function will compare each value, one by one. Lets apply the same to emp table. We have some NULL values in comm and mgr columns. but not in any other columns. So lets take a example for this 2 columns. COALESCE(comm,mgr,sal) Here if comm is null, function returns mgr value. If mgr is null it returns sal value! Query used in video: SELECT ename,comm,mgr,sal,COALESCE(comm,mgr,sal) result FROM emp;

We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure.

Explaining the Explain Plan: Interpreting Execution Plans for SQL Statements
 
01:04:02
Presenter: Maria Colgan, Oracle Corporation The execution plan for a SQL statement can often seem complicated and hard to understand. Determining if the execution plan you are looking at is the best plan you could get or attempting to improve a poorly performing execution plan can be a daunting task, even for the most experienced DBA or developer. This session examines the different aspects of an execution plan, from selectivity to parallel execution, and explains what information you should be gleaming from the plan and how it affects the execution. It offers insight into what caused the Optimizer to make the decision it did as well as a set of corrective measures that can be used to improve each aspect of the plan.

SQL Tutorial - PIVOT

Another video brought to you by BeardedDev, bringing you tutorials on Business Intelligence, SQL Programming and Data Analysis. In this video I talk about using PIVOT in Microsoft SQL Server. T-SQL Querying https://www.amazon.com/gp/product/0735685045/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=0735685045&linkCode=as2&tag=beardeddev05-20&linkId=e93b0f7483b1fa06aca5a3aec4f7764b T-SQL Fundamentals https://www.amazon.com/gp/product/150930200X/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=150930200X&linkCode=as2&tag=beardeddev05-20&linkId=70aa2ffa3e84cab66cb964ca1e9cee62 Microsoft SQL Server 2012 High-Performance T-SQL Using Window Functions https://www.amazon.com/gp/product/0735658366/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=0735658366&linkCode=as2&tag=beardeddev05-20&linkId=b88746aea666c9f98da147e70b4491ca Using PIVOT allows us rotate data from rows to columns making the data more readable. PIVOT is ideal for reporting in SQL Server and can be used as a starting point to visualise trends. In this PIVOT tutorial I demonstrate the difference between how data is presented compared to GROUP BY. PIVOT Syntax SELECT [columns] FROM ( [source_query] ) PIVOT ( [aggr_function]([aggr_column] FOR [spreading_column] IN ([spreading_elements])) SQL Queries in the video: Results using GROUP BY statement SELECT Sales_Customer_Id , DATENAME(MONTH, Sales_Date) AS [Month] , Sales_Amount FROM dbo.Sales GROUP BY Sales_Customer_Id , DATENAME(MONTH, Sales_Date) Results using PIVOT statement SELECT Sales_Customer_Id , [January] , [February] , [March] FROM ( SELECT Sales_Customer_Id , DATENAME(MONTH, Sales_Date) AS [Month] , Sales_Amount FROM dbo.Sales ) AS Src PIVOT ( SUM(Sales_Amount) FOR [Month] IN ([January], [February], [March]) ) AS Pvt Alternative PIVOT statement SELECT [Month] , [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] FROM ( SELECT Sales_Customer_Id , DATENAME(MONTH, Sales_Date) AS [Month] , Sales_Amount FROM dbo.Sales ) AS Src PIVOT ( SUM(Sales_Amount) FOR Sales_Customer_Id IN ([1], [2], [3], [4], [5], [6], [7], [8]) ) AS Pvt Please feel free to post comments.
