SQL: Delete Vs Truncate Vs Drop
 
08:27
In this tutorial, you'll learn the difference between delete/drop and truncate. 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.

Oracle Database In-memory: не просто кэш

Доклад Александра Бреймана "Oracle Database In-memory: не просто кэш", сделанный на конференции для разработчиков программного обеспечения (ORACLE) DevLabs 2014 (22 ноября 2014 г.). Александр Брейман – специалист по разработке и архитектуре ПО Luxoft Training: http://www.luxoft-training.ru/about/experts/breiman.html Обычно узким местом в системах управления данными является дисковая подсистема, и большая часть хитростей разработчиков СУБД направлена на то, чтобы обращаться к диску как можно реже. Но если вся база данных помещается в память, то, наверное, все эти хитрости становятся ненужными? Может быть, достаточно выделить побольше памяти под буферы, и все сразу станет хорошо? Или все не так просто? Зачем все эти TimesTen, SAP HANA, а теперь (начиная с 12.1.0.2) и Oracle Database In-memory? Все эти вопросы разбирает автор доклада.

Benefits of Common Table Expressions
 
05:56
On this episode of Joes 2 Pros SQL server unlocked series we present a topic for anyone who has ever been exposed to SQL Server, Common Table Expressions. A CTE is memory resident table. You are pulling from that query and giving it a name. This table adds enhancements to the old tables. It allows you to open up to new people without having an increased security risk. This is extremely beneficial for anyone who is exposed to SQL Server as keeping your content safe is a top concern for most organizations. In this video, he will take you through a very real example from a department store quarterly reporting. He wants to do a seasonal reporting from all the departments of a store excluding snow sports and cooking. He shows you how to make the code more simple and reduce human error. Having CTE knowledge will be greatly beneficial to you in your everyday career. Please be sure to follow along our blog series. Stay tuned next week to learn more about Dynamic SQL. To learn more about he benefits of common table expressions view our course Developer 2012 Volume 2 Video 10.1.

Getting Started with PL/SQL Table Functions: Pipelined Table Functions
 
14:49
Pipelined table functions are table functions in which rows are returned or "piped" back to the calling query before the function has completed, avoiding the blocking behavior of normal PL/SQL functions and reduce PGA consumption. This video is part of the Oracle Dev Gym class "Getting Started with Table Functions". You can watch it independent of the class, but then you miss out on the tutorials and quizzes! So visit https://devgym.oracle.com/pls/apex/dg/class/getting-started-with-pl-sql-table-functions.html and register for the class! ======================================== Practically Perfect PL/SQL with Steven Feuerstein Copyright © 2018 Oracle and/or its affiliates.
