These functions include building database objects, manipulating objects, populating database tables with data, updating existing data in tables, deleting data, performing database queries, controlling database access, and overall database administration. The main categories are DDL (Data Definition Language) DML (Data Manipulation Language) DQL (Data Query Language) DCL (Data Control Language) Data administration commands Transactional control commands Defining Database Structures Data Definition Language, DDL, is the part of SQL that allows a database user to create and restructure database objects, such as the creation or the deletion of a table. Some of the most fundamental DDL commands discussed during following hours include the following: CREATE TABLE ALTER TABLE DROP TABLE CREATE INDEX ALTER INDEX DROP INDEX CREATE VIEW DROP VIEW Manipulating Data Data Manipulation Language, DML, is the part of SQL used to manipulate data within objects of a relational database. There are three basic DML commands: INSERT UPDATE DELETE Selecting Data Though comprised of only one command, Data Query Language (DQL) is the most concentrated focus of SQL for modern relational database users. The base command is as follows: SELECT This command, accompanied by many options and clauses, is used to compose queries against a relational database. Queries, from simple to complex, from vague to specific, can be easily created. The SELECT command is discussed in exhilarating detail during Hours 7 through 16. A query is an inquiry to the database for information. A query is usually issued to the database through an application interface or via a command line prompt. Data Control Language Data control commands in SQL allow you to control access to data within the database. These DCL commands are normally used to create objects related to user access and also control the distribution of privileges among users. Some data control commands are as follows: ALTER PASSWORD GRANT REVOKE CREATE SYNONYM You will find that these commands are often grouped with other commands and may appear in a number of different lessons throughout this book. Data Administration Commands Data administration commands allow the user to perform audits and perform analyses on operations within the database. They can also be used to help analyze system performance. Two general data administration commands are as follows: START AUDIT STOP AUDIT Do not get data administration confused with database administration. Database administration is the overall administration of a database, which envelops the use of all levels of commands. Database administration is much more specific to each SQL implementation than are those core commands of the SQL language. Transactional Control Commands In addition to the previously introduced categories of commands, there are commands that allow the user to manage database transactions. COMMIT Saves database transactions ROLLBACK Undoes database transactions SAVEPOINT Creates points within groups of transactions in which to ROLLBACK SET TRANSACTION Places a name on a transaction

Oracle SQL Tuning - How to Read Execution Plans (Explain Plan)
 
13:39
In this free tutorial you will learn how to generate and read (interpret) an execution plan in Oracle Databases. See more FREE Oracle Tuning tutorials at http://skillbuilders.com/free-oracle-tutorials. Understanding what the Oracle Database does with your SQL is essential to tuning - and the execution plan is the key. Oracle Certified Master DBA John Watson will provide a brief introduction (4 minutes) - which includes John's tuning methodology, then demonstrate EXPLAIN PLAN, SQL*Plus AUTOTRACE and DBMS_XPLAN.DISPLAY_CURSOR. In the tutorial, John will teach you: - How to read an execution plan - Find the 1st step in the plan - Decipher the order of the steps in the plan - That EXPLAIN PLAN can be very misleading Prerequisites: To get the most from this tutorial, you should: 1 Know how to code SQL 2 Be familiar with SQL*Plus 3 Know - in very general terms - what an execution plan is. 4 Have a basic understanding of the Library Cache (this is where Oracle Database stores parsed SQL statements) 5 Have a basic understanding of the Cost Based Optimizer (this is the part of the database that parses your SQL, creates an execution plan. Hopefully the correct - most efficient - plan).

Indexes in SQL Server -- making queries run faster
 
10:57
Indexes in SQL Server make queries run faster and more efficiently. With the size of databases increasing almost exponentially, being able to return results quickly with minimal stress on the underlying server is crucial. This tutorial includes a practical demonstration of performance gains obtained from creating Clustered, Non-Clustered, and Column indexes. In the demonstration clustered and non-clustered indexes result in a 10 x increase in query performance compared to using no index. The Column index results in further a 10 x increase in performance over the Clustered and Non-clustered indexes (100 x faster than using no index). The video also outlines the basic concepts behind indexes and demonstrates how to quickly created indexes in SQL Server Management studio. Code and sample databases are available from http://www.analyticsinaction.com/indexes/ I also have a comprehensive 60 minute T-SQL course available at Udemy : https://www.udemy.com/t-sql-for-data-analysts/?couponCode=ANALYTICS50%25OFF

How Many Indexes Are Too Many?: Finding All The Red Sweets Part 5
 
10:58
Every index you add to a table increases its storage requirements and DML overheads. So it's a good idea to create as few as possible. When you have two or more indexes using the same columns, you may be able to get away with just one. But how do you decide which to keep? This video discusses how to analyze your queries so you can cut the number of indexes you create. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.

CREATE TABLE command in sql/oracle,INSERT command in sql/oracle UPDATE,ALTER PASSWORD command in sql, GRANT command, REVOKE command i, CREATE SYNONYM command in sql/oracle, DELETE command in sql/oracle, ALTER TABLE command in sql/oracle, DROP TABLE command in sql/oracle, CREATE INDEX command in sql/oracle, ALTER INDEX command in sql/oracle, DROP INDEX command in sql/oracle, CREATE VIEW command in sql/oracle, DROP VIEW command in sql/oracle USING SQL COMMAND Types of SQL Commands The following sections discuss the basic categories of commands used in SQL to perform various functions. These functions include building database objects, manipulating objects, populating database tables with data, updating existing data in tables, deleting data, performing database queries, controlling database access, and overall database administration. The main categories are DDL (Data Definition Language) DML (Data Manipulation Language) DQL (Data Query Language) DCL (Data Control Language) Data administration commands Transactional control commands Defining Database Structures Data Definition Language, DDL, is the part of SQL that allows a database user to create and restructure database objects, such as the creation or the deletion of a table. Some of the most fundamental DDL commands discussed during following hours include the following: CREATE TABLE ALTER TABLE DROP TABLE CREATE INDEX ALTER INDEX DROP INDEX CREATE VIEW DROP VIEW Manipulating Data Data Manipulation Language, DML, is the part of SQL used to manipulate data within objects of a relational database. There are three basic DML commands: INSERT UPDATE DELETE Selecting Data Though comprised of only one command, Data Query Language (DQL) is the most concentrated focus of SQL for modern relational database users. The base command is as follows: SELECT This command, accompanied by many options and clauses, is used to compose queries against a relational database. Queries, from simple to complex, from vague to specific, can be easily created. The SELECT command is discussed in exhilarating detail during Hours 7 through 16. A query is an inquiry to the database for information. A query is usually issued to the database through an application interface or via a command line prompt. Data Control Language Data control commands in SQL allow you to control access to data within the database. These DCL commands are normally used to create objects related to user access and also control the distribution of privileges among users. Some data control commands are as follows: ALTER PASSWORD GRANT REVOKE CREATE SYNONYM You will find that these commands are often grouped with other commands and may appear in a number of different lessons throughout this book. Data Administration Commands Data administration commands allow the user to perform audits and perform analyses on operations within the database. They can also be used to help analyze system performance. Two general data administration commands are as follows: START AUDIT STOP AUDIT Do not get data administration confused with database administration. Database administration is the overall administration of a database, which envelops the use of all levels of commands. Database administration is much more specific to each SQL implementation than are those core commands of the SQL language. Transactional Control Commands In addition to the previously introduced categories of commands, there are commands that allow the user to manage database transactions. COMMIT Saves database transactions ROLLBACK Undoes database transactions SAVEPOINT Creates points within groups of transactions in which to ROLLBACK SET TRANSACTION Places a name on a transaction

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.
