Oracle SQL Tutorial 21 - How to Create / Drop Indexes
 
03:58
In the last video, we wrote up the SQL to create three tables: CREATE TABLE users( user_id NUMBER, username VARCHAR2(50 CHAR) UNIQUE, CONSTRAINT users_pk PRIMARY KEY (user_id) ); CREATE TABLE projects( project_id NUMBER, Project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL, CONSTRAINT projects_pk PRIMARY KEY (project_id), CONSTRAINT projects_users_fk FOREIGN KEY (creator) REFERENCES users (username) ON DELETE CASCADE ); CREATE TABLE project_users( project_id NUMBER NOT NULL REFERENCES projects (project_id) ON DELETE CASCADE, user_id NUMBER NOT NULL REFERENCES users (user_id) ON DELETE CASCADE, CONSTRAINT project_users_pk PRIMARY KEY (project_id, user_id) ); I'm going to increase the size of the users table a bit by adding a first and last name column. CREATE TABLE users( user_id NUMBER, username VARCHAR2(50 CHAR) UNIQUE, first_name VARCHAR2(50 CHAR), last_name VARCHAR2 (50 CHAR), CONSTRAINT users_pk PRIMARY KEY (user_id) ); But before we finish this design, we should consider indexing certain columns. What columns should we index? Well, as a reminder, the columns that are indexed by default are columns with the UNIQUE constraint, and those that are labeled as primary keys. Columns that are not indexed but often should be are those labeled as a foreign key. The column that jumps out the most to me is the creator column of the project table. It's the only foreign key that is not part of some index. Let's fix this by creating our first index. The way we do that is with the CREATE INDEX command. CREATE INDEX projects_creator_ix ON projects (creator) What naming convention are we following for the index? We are naming it by the table name, followed by an underscore, followed by the column, followed by an underscore, followed by an ix (for index). In this situation it does not apply, but if our foreign key column is labeled as UNIQUE, we can add the UNIQUE keyword like this: CREATE UNIQUE INDEX projects_creator_ix ON projects (creator) Now if you want to get rid of an INDEX, you can use this command: DROP INDEX projects_creator_ix Now, if we want to select data from the user table and the project table we can do that much faster. That's because the foreign key and column it references are both indexed and those are the columns we would do the join on. We will discuss how to do joins in a future video. So what are some potential problems with this database design? Overall, it is pretty good. With this design though we need to make sure there is no way for someone to update a user's username. In the next video we are going to discuss why. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me on Patreon! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Identifying & Locking default (service) accounts in Oracle
 
01:37
Oracle default installation comes up with several database accounts that're opened and have escalated privileges. Oracle database installs with a number of default database user accounts. Upon successful installation of the database, the Database Configuration Assistant automatically locks and expires most default database user accounts. If you perform a manual (without using Database Configuration Assistant) installation of Oracle Database, then no default database users are locked upon successful installation of the database server. Or, if you have upgraded from a previous release of Oracle Database, you might have default accounts from earlier releases. Left open in their default states, these user accounts can be exploited, to gain unauthorized access to data or disrupt database operations. You should lock and expire all default database user accounts. Oracle Database provides SQL statements to perform these operations.

Difference between an Oracle user and schema - Database Tutorial 59 - Oracle DBA Tutorial An Oracle user is an account that is owned by an employee. These user accounts are not expected to create any objects. However they will be given access to objects owned by the schemas. A schema is a generic user. But it will own objects that are used by the other users and the applications.

Oracle SQL Tutorial 11 - CREATE TABLE
 
05:04
The way you create a table is to use the CREATE TABLE command. CREATE TABLE users() So in this situation, the name comes right after the TABLE keyword. The next thing we do is put all of the columns on a line that we want to put in our table. CREATE TABLE users( user_id, username, first_name, last_name ) Notice the naming conventions here. For this series we are going to make columns with what is known as snake casing. This is where each individual word is separated by an underscore. if you have more than one column, all of them have to have commas except the last one. The comma is a way to say that another column is coming, so you don't need to do it on the last one. Now you would think we were done, but we also have to say what data type each column is. Later we will extensively discuss data types so we can focus on them exclusively. For now, here are the data types we are going to use: CREATE TABLE users( user_id NUMBER, username VARCHAR2(50), first_name VARCHAR2(50), last_name VARCHAR2(50) ) Now, inside of the parenthesis for varchar2, we pass in a number... This is the max length of the string. But the question is, what is it measured in? The default is actually in bytes, not characters. For example if we have the string hello, it is 5 characters, but it might take up a total of 10 bytes of storage. So I would recommend adding the keyword char right after the number so it defaults to 50 characters, not bytes. CREATE TABLE users( user_id NUMBER, username VARCHAR(50 CHAR), first_name VARCHAR2(50 CHAR), last_name VARCHAR2(50 CHAR) ) This will work to create a table, but it's really missing a lot of information… which column is the primary key? Are we adding any indexes? Is there any thing else we need to say about these columns? So as you can tell, we are making progress, but there is still so much to learn. The biggest gotcha to remember from this video is that the data type VARCHAR ends in a 2, stupid, right? who would end the name of something with a 2?

[CSIS 1550] - MySQL: Views, Users, Indexes and Constraints
 
01:17:30
[CSIS 1550] - MySQL: Views, Users, Indexes and Constraints OVERVIEW This lecture introduces us to various tasks performed by and responsibilities of the database administrator (DBA). * VIEWS * Creating simple views * Creating views from joins * Creating views with custom field names * Pros and Cons of Views * USERS * Creating * Granting rights * Revoking rights * Removing users * Note: Public key word (page 194) does not work * INDEXES * Creating * Dropping * Unique Indexes * Data Integrity * Constraints READING ASSIGNMENT The lecture is based on pages 181 through 205 of the text book ACTIVITIES In class, we will work through several examples together. Each of these exercises will refresh our memories of earlier concepts we've learned, and will further build on them as we create views, users, indexes and constraints. CODE - Views To create a view, use the following structure shown below CREATE VIEW [Give the View a Name] [(enter custom field names, in parenthesis, if you want)] AS [Some query]; For example: CREATE VIEW REP2 (ID, NAME) AS SELECT REP_NUM, CONCAT(FIRST_NAME, " ", LAST_NAME) FROM REP; The above will create a view called "REP2" that uses ID and NAME as the field names. It will give you a view like this: SELECT * FROM REP2; +----+-----------------+ | id | name | +----+-----------------+ | 20 | Kaiser, Valerie | | 35 | Hull, Richard | | 65 | Perez, Juan | +----+-----------------+ Users: creation Creating users is a simple process. Below is the structure: CREATE USER '[Give the User a Name]' IDENTIFIED BY '[Give the User a Password]'; For example: CREATE USER 'Beavis' IDENTIFIED BY 'Password'; Users: access Once a users are created, you can grant them various levels of access using the following structure: GRANT [List Privilege(s) Here] [(field names, if you'd like)] ON [Database Name Here].[Table Name Here] TO [User's Name Here]; For Example, the query below will grant user "Beavis" the ability to select the REP_NUM, FIRST_NAME and LAST_NAME fields from the Rep table in the Premiere database: GRANT SELECT (REP_NUM, LAST_NAME, FIRST_NAME) ON PREMIERE.REP TO 'Beavis'; To revoke access, the syntax is very similiar: REVOKE [List Privilege(s) separated by commas Here] ON [Database Name Here].[Table Name Here] FROM [User's Name Here]; For example, the query below will revoke all privileges on all tables in all databases from user "Beavis." REVOKE ALL ON *.* FROM 'Beavis'; Below is a list of some of the privileges that can be granted or revoked: UPDATE INSERT DELETE SELECT DROP ALTER ALL Indexes Indexes make it much quicker to access records in a database. The syntax for creating, viewing and dropping an index is as follows: CREATE INDEX [Give the Index a Name] ON [Name of the Table] ([Field Name sort direction, Field Name sort direction, etc.]) SHOW INDEX FROM [Table Name]; DROP INDEX [Index Name] ON [TABLE]; For example: CREATE INDEX CustName ON CUSTOMER (CUSTOMER_NAME DESC); SHOW INDEX FROM CUSTOMER; DROP INDEX CustName on CUSTOMER; Unique Index Unique indexes have two purposes. They act as a standard index (see above) They prevent duplicate data entry (much like a primary key) The syntax is identical to the standard index syntax with one exception. The word "UNIQUE" is used in the CREATE query. CREATE UNIQUE INDEX [Give the Index a Name] ON [Name of the Table] ([Field Name sort direction, Field Name sort direction, etc.)] Constraints As a control freak we want to make sure that we protect the data every way we know how. Contraints can be a very useful tool for that very purpose. There are many types of constraints. Here are just a few: * Primary Keys * Foreign Keys * Legal Values Our focus today is on Foreign Keys. Enforcing a Foreign Key Constraint will prevent a user from being able to add a foreign key value in a table if it does not already exist as a Primary Key in a specified table. For example, to prevent users from enter a rep_num value in the customer table that does not exist in the rep table, we can use a foreign key constraint: ALTER TABLE CUSTOMER ADD FORIEGN KEY (REP_NUM) REFERENCES REP(REP_NUM); Currently, the only rep_num values in the rep table are 20, 35 and 65. If a user tries to use the value 75 (for example) in the customer table, the above Constraint prevents that from happening because 75 is not a valid rep_num in the rep table.

How to Create an user in Oracle
 
14:49
How to Create an user in Oracle with minimum grants/privileges we need to connect as SYSDBA lets ceate an user test you can see the user is created : But can it connect? lets open a new session we can see it lacks create session priv. so, we grant the create session privilege to user test lets test Its connecting. But is it able to create a table ,lets check. it lacks the ability to create table. SO lets give the privilege. lets test again the create table command. its throwing error regarding no Privilege on users tablespace . But we have given USERS as the default tablespace to test(user). So whats the problem? The problem is there is not quota defined for user test. lets give some quota like "10MB" or UNLIMITED , we will giev 10MB NOw let us test. So we can see that we now have sufficient / minimum privileges for the user test. Hope this will help in understanding the concept behind user creation

Oracle 12c Database New Features - Pluggable Database - Video 1
 
17:25
Oracle 12c Database New Features - Pluggable Database - Video 1 1. Pluggable Database * Oracle 12c introduces a new feature called 'Pluggable Database'. Here Oracle Metadata and user data are totally separated into two sections. One is Container DB (or CDB) which will hold Oracle Metadata. The other is Pluggable DB (or PDB) which will hold user data. How does a Pluggable Database work? In the regular database, Oracle's metadata and user's application data are integrated. For beginners, Oracle Metadata is the data that is present when you install a new Oracle Database (without any sample schemas). Even though it can be called as an empty database, it still has data provided by Oracle. This data is needed by the database to function. For example, the objects owned by SYS, SYSTEM are mostly metadata. Then user data is entered into that database. They will go under multiple user schemas. Now the database is being used by the users. Now a situation arises so that we need to create another database on the same server. Why? Let us say that you need to provide data to two clients. And you don't want one client to other's data. And your data is contained in an extensive set of application schemas. In this case, making a copy of those applications schemas into a different set of names and making them reside in the same database is very difficult. So, you provide two separate databases. This also ensures that there is no security violation. So, we install another new database, which comes with Oracle Metadata. Then we load the user data. In this method, which is currently being used (Year 2013), there will be a need for more memory for both the database instances. There will be two SGAs, two sets of smon, pmon and other background processes running. Then if we need to copy one database to another, we need to rely on extensive procedures which includes exporting the data from the source database first, then removing the data at the target and then finally loading the data in there. After that, we need to take care of the user security and object privileges etc. So, if you want to provide data for multiple tenants, that is multiple clients, then with the current set of features (till Oracle 11g), we have to create multiple databases. That is, one database for one client. In otherwords, there is no multi-tenancy. Multi-Tenancy is becoming an important requirement in cloud infrastructure, these days. You would like to have the ability of providing data to multiple clients from the same database system with full confidence in security. This can be achieved in Pluggable Database. In a Pluggable Database, Oracle basically separates its metadata entirely from the user data. Metadata is stored in a section called Container DB. Then the user data are stored in Pluggable DBs. It also stores user metadata in the Pluggable DB. By the way, what is user metadata? For example, earlier, the list of user accounts that exist in a database is tightly inegrated with Oracle Metadata. Now, with the separation of Container DB and Pluggable DB, the user accounts must exist in the Pluggable DB. So, the Pluggable DB not only contains user data, but also some user metadata. So, what are the benefits? * Multi-Tenancy - We can bring in two Pluggable DBs under one Container DB. Both will be totally segregated, but yet controlled by one instance. This is an important feature for SaaS (Software as a Service) platforms, Cloud, On-Demand and Vendor Managed Application solutions. * Easy cloning/copying. Now the cloning and copying the databases across servers would be much easier. Just clone a Pluggable DB and plug-it-in in a different server. * Very easy upgrades and patching.

In the previous login videos I have on this channel, there were some loopholes like when a user enters the index.php on the url without having logged in, it still takes them to the home page. But that is not secure. This new video checks that and makes sure it automatically redirects any request to the login page when it finds out that the user isn't logged in. - - - - - - - - - - - - - - - - - - - C O U R S E S - - - - - - - - - - - - - - - - - - - { B O O T C A M P S } - - The Web Developer Bootcamp: http://bit.ly/2NpDcKR - - The Complete Web Developer in 2018: Zero to Mastery: http://bit.ly/2N0ZW4F { P H P } - - PHP for Beginners - Become a PHP Master - CMS Project: http://bit.ly/2u5QMIw - - Create a REAL Social Network like Facebook in PHP + MySQL: http://bit.ly/2wUv3om - - PHP with Laravel for beginners - Become a Master in Laravel: http://bit.ly/2QcbeRf - - PHP OOP - Understand Object Oriented Programming in PHP: http://bit.ly/2CysNs3 { P Y T H O N } - - Complete Python Bootcamp: Go from zero to hero in Python 3: http://bit.ly/2wSybRs - - Complete Python Masterclass: http://bit.ly/2oNWfQW { J A V A S C R I P T } - - Modern JavaScript From The Beginning: http://bit.ly/2wUHdwD - - The Complete JavaScript Course 2018: Build Real Projects!: http://bit.ly/2wUlZ1L - - Modern React with Redux: http://bit.ly/2QcWBx0 - - MERN Stack Front To Back: Full Stack React, Redux & Node.js: http://bit.ly/2CAaeDY

Create workspace on Oracle Apex 5.1: ============================== Oracle Application Express is Oracle's primary tool for developing Web applications with SQL and PL/SQL. Using only a web browser, you can develop and deploy professional Web-based applications for desktops and mobile devices. Create Workspace First, you need to log in the administration system of Oracle APEX in order to declare a Workspace. A Workspace will work with a SCHEME in database. Workspace contains Applications including a system of forms, reports, and so on, managing users who participate in programming, or users who use the application. • Open your internet browser, then write following URL in address bar for log in http://localhost:8080/apex/apex_admin • After log in, You need to create new Workspace: Click on create workspace • Enter: Workspace Name: my_ws Then click Next. • You can select a SCHEMA available in Database. Here I create a new SCHEMA named my_ws with password my_ws, and Re-use existing schema? No, then click on Next. • In the previous step, you created a SCHEMA named my_ws. It means 1 user database is created and named my_ws. • In this step, you need to declare a administration User of Workspace. It is not a user database, but it is a administration user of this Workspace. It is capable of creating applications, other Users as programmers, or users who use the application... Enter: User Name: my_ws_admin Password: my_ws_admin Email: [email protected] Then click Next. And then confirm your request by clicking Create Workspace, Finally click on Done. Note: Your Workspace has been created. You can see the list of current Workspace and edit if you want. • To find your workspace: Click on Manage Workspaces, Find Workspace Work with Workspace • In the above step, you created a Workspace named my_ws. Now we will log in and work with this Workspace: Open your internet browser, and then write following URL in address bar for log in http://localhost:8080/apex Enter: Workspace: my_ws User Name: my_ws_admin Password: my_ws_admin Then click Next. • In the first time of logging in Workspace, the system requires you to change your password, but you can keep your password intact • You are logged in my_ws Workspace Follow me: https://www.facebook.com/leens.tech https://www.facebook.com/munir.du https://twitter.com/munir_du https://www.linkedin.com/in/md-munir-hussain Contact me: [email protected] Download Oracle Database 11g R2 from: http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win32soft-098987.html Download Oracle Apex 5 from: http://www.oracle.com/technetwork/developer-tools/apex/downloads/index.html

Simplified DBA-019-Data Concurrency and Locks
 
03:56
DATA CONCURRENCY More than one user connections ( session ) can access same data. For example user1 and user2 can view same employee information at the same time. But not two users can modify same data in one time. This is maintained by oracle lock mechanism. Before the database allows a session to modify data, the session must first lock the data that is being modified. A lock gives the session exclusive control over the data so that no other transaction can modify the locked data until the lock is released. Transactions can lock individual rows of data, multiple rows, or even entire tables. Oracle Database supports both manual and automatic locking. Automatically acquired locks always choose the lowest possible level of locking to minimize potential conflicts with other transactions. Demo: User1 is modifying an employee. User1 session will acquire a lock on the row. Same time user2 is trying to modify same employee. Since User1 has acquired lock, user2 has to wait until user1 releases the lock. Manual locking is possible. A user can place a lock manually as follows: LOCK TABLE mytable1 IN EXCLUSIVE MODE; With the preceding statement, any other transaction that tries to update a row in the locked table must wait until the transaction that issued the lock request completes. EXCLUSIVE is the strictest lock mode. The following are the other lock modes: ROW SHARE: Permits concurrent access to the locked table but prohibits sessions from locking the entire table for exclusive access ROW EXCLUSIVE: Is the same as ROW SHARE, but also prohibits locking in SHARE mode. The ROW EXCLUSIVE locks are automatically obtained when updating, inserting, or deleting data. ROW EXCLUSIVE locks allow multiple readers and one writer. SHARE: Permits concurrent queries but prohibits updates to the locked table. A SHARE lock is required (and automatically requested) to create an index on a table. However, online index creation requires a ROW SHARE lock that is used when building the index.
