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? Once again, this is Caleb from CalebTheVideoMaker2, and we will catch you in the next one! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ HELP ME! 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!)

Oracle SQL Tutorial 5 - Database Integrity - Database Design Primer 2
 
12:18
This is the second video in the 5 database design videos in my oracle sql tutorial series. This video discusses database integrity. Database integrity is broken up into 3 sections: entity integrity, referential integrity, and domain integrity. Entity integrity focuses on the primary key. A primary key should be unique, NOT NULL, and never changing. It should refer to only one individual entity. Referential integrity focuses on protecting the relationships between entities of different tables. When creating relationships between tables, you will associate a column with another column in a different table. Individual entities inside of this table should have relationships with individual entities in the other table. For example, a comment table might have a user_id column. Each individual comment (each row), should have a user_id that points to a user_id in the user table. We protect referential integrity with what are known as foreign key constraints. Domain integrity focuses on the allowed values within a database. This one is probably the most complex because there are so many different things you can do to protect this, some of which involve a server side scripting language to add even more complex rules such as regular expressions. Fortunately, Oracle SQL is a pretty big database system and surely has lots of features that can be used to allow domain integrity.

Oracle SQL Tutorial 7 - Normalization - Database Design Primer 4
 
20:38
The database normal forms are used to normalize a database. What does it mean to normalize a database? It means to break it up into multiple tables to prevent redundant, conflicting, and bad data. The three normal forms are 1nf, 2nf, and 3nf. These stand for first normal form, second normal form, and third normal form. There are other normal forms, such as Boyce Codd normal form (BCNF), but the first 3 normal forms are the ones that are really important to know. The normal forms depend on one another. It is kind of like a ladder. In order to be in 2nd normal form, you must first be in first normal form. In order to be in 3rd normal form, you must first be in 2nd normal form. First normal form is all about individuality and giving data its space. Each column must be atomic...that is, in the smallest indivisible piece. Each value for the column must also only contain one value. To fix first normal form when you have a column violation, break the column into multiple columns. To fix first normal form when you have data violation, break the column into a new table and have a column that references the old table. Second normal form is all about partial dependencies. A partial dependency is when a column only depends on part of the primary key. This is often seen when you have an intermediary table in a many to many relationship (as a reminder, we break up many to many relationships into one to many relationships with intermediary tables in between). The solution to get rid of partial dependencies is to put the data in the table to where the column depends entirely on the key. If you do not already have a table that fits the rule, you can consider creating one. Third normal form is all about transitive dependencies. This is when a column in a table depends on another column instead of depending solely on the primary key. The solution to this is to take the column that is directly dependent on the primary key and bring it into its own table. Then, you can use foreign keys to connect the tables. This video concluded with a noble speech on how database design is very subjective. Thus is so because as we normalize more and more, the design becomes more and more complex. If we get to the point where we have hundreds of tables for a relatively small database, we can really hurt performance and increase risk of mistakes. Hopefully this video was helpful to everyone.

Oracle SQL Tutorial 13 - How to Add Column Constraints (Attributes)
 
05:55
So far, we have this table declaration: CREATE TABLE users( user_id NUMBER, username VARCHAR(50 CHAR) first_name VARCHAR2(50 CHAR), last_name VARCHAR2(50 CHAR) ) We can run this command see that it works. As we are learning though, we are going to want to be able to recreate our table with different settings and such, but if you try to run this command, it will complain that the table already exists. So we first need to delete this table before we start editing settings. When we get more experienced, we will learn about ways to edit the structure of a table that already exists. To fix this, we can get rid of the table using the DROP TABLE command: DROP TABLE users You can run this every time if you need to practice by adding a semicolon after it. This is how you can tell Oracle that you are putting in another command after it. This is known as a delimiter. When you run the script, it is going to run both commands. Now we can go through and reconsider our table structure. This is fine for starting out because we don't have any important data in our database, but once your database is in production you are not going to want to just drop tables. In the last video we discussed different constraints that you can apply to columns in a database table, but how do you actually apply these when you are creating a table? The first way you define constraints is to put them right after the column in your CREATE TABLE statement. CREATE TABLE users( username VARCHAR2(50 CHAR) NOT NULL ) When we define constraints this way, we usually say we are adding column attributes. If you have two constraints you want to add, you just put one after the other with spaces in between. There is no particular order that is required. CREATE TABLE users( username VARCHAR2(50 CHAR) NOT NULL UNIQUE ) In this situation we have already given the column the NOT NULL and UNIQUE attributes, so we should consider making this a primary key: CREATE TABLE users( username VARCHAR2(50 CHAR) PRIMARY KEY ) As you can see, adding column attributes is super easy. We can add a default like this: CREATE TABLE users( username VARCHAR2(50 CHAR) PRIMARY KEY, account_balance NUMBER DEFAULT 0 ) Note that now we need the comma after the first row. There are a few constraints we did not talk go through an example, specifically foreign keys and check constraints. We will be adding these constraints to our database in future videos. In the mean time, I have a thought for you… Many people prefer to name their column constraints. That way, we can refer to certain constraints by name. For example, we might have a primary key constraint that could be named users_pk. The way we are creating these constraints does not allow for this feature, so in the next video we are going to be discussing different ways to create constraints. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

Create table tblEmployee ( ID int primary key identity, Name nvarchar(50), Gender nvarchar(50), Salary nvarchar(50) ) Insert into tblEmployee values('Sara Nani','Female','4500') Insert into tblEmployee values('James Histo','Male','5300') Insert into tblEmployee values('Mary Jane','Female','6200') Insert into tblEmployee values('Paul Sensit','Male','4200') Insert into tblEmployee values('Mike Jen','Male','5500') The requirement is to group the salaries by gender. To achieve this we would write a sql query using GROUP BY as shown below. Select Gender, Sum(Salary) as Total from tblEmployee Group by Gender When you execute this query, we will get an error - Operand data type nvarchar is invalid for sum operator. This is because, when we created tblEmployee table, the "Salary" column was created using nvarchar datatype. SQL server Sum() aggregate function can only be applied on numeric columns. So, let's try to modify "Salary" column to use int datatype. Let's do it using the designer. 1. Right click on "tblEmployee" table in "Object Explorer" window, and select "Design" 2. Change the datatype from nvarchar(50) to int 3. Save the table At this point, you will get an error message - Saving changes is not permitted. The changes you have made require the following tables to be dropped and re-created. You have either made changes to a table that can't be re-created or enabled the option Prevent saving changes that require the table to be re-created. So, the obvious next question is, how to alter the database table definition without the need to drop, re-create and again populate the table with data? There are 2 options Option 1: Use a sql query to alter the column as shown below. Alter table tblEmployee Alter column Salary int Option 2: Disable "Prevent saving changes that require table re-creation" option in sql server 2008 1. Open Microsoft SQL Server Management Studio 2008 2. Click Tools, select Options 3. Expand Designers, and select "Table and Database Designers" 4. On the right hand side window, uncheck, Prevent saving changes that require table re-creation 5. Click OK

APEX08.DB01:  Dynamic versus static LOV (list of values).  Add a uniqueness constraint to a column.
 
10:27
This video gives examples of static LOVs and dynamic LOVs and their use of data from the database. Static LOVs are manual lists that only exist in APEX. A dynamic LOV uses data from a table in the database. Also, a uniqueness constraint is added to the text column in the two lookup tables we had APEX Object Browser create in previous videos.

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. Thats it
