Hibernate: How to Implement a Custom, Sequence-Based ID Generator
 
09:36
Today I will show you how you can Implement a Custom, Sequence-Based ID Generator with #Hibernate. A lot of applications use primary keys that are based on a sequence but use an additional prefix that contains semantic information.

How to generate primary keys with JPA and Hibernate
 
09:08
Today, I will show you how to generate unique primary key values with JPA and Hibernate. But before we start, I want to know how you get the primary key values in your application? Do you use natural keys or UUIDs or do you generate technical IDs? Please post a comment below and tell me about it. I prefer to generate simple, numerical, technical IDs like you can see in the following code snippet instead of using natural keys which often require the combination of multiple attributes. Technical IDs are easier to manage and all involved systems, mainly the database and Hibernate, can index them very efficiently. This allows you to focus on the business logic of your application and avoids performance issues. If you like this video, please give me your thumbs up and share it with your friends and co-workers.

In this video tutorial I will be showing how to generate primary key automatically using the hibernate framework .The basic way of doing this is by using the generator property. The code is available here - http://www.vnrgroups.com/articles/java-hibernate-tutorial-part-6 In the video I will show how to use the sequence and increment generator values I will also show the use of the unsaved-value property in the video. The unsaved-value is used when we use the save or update method saveOrUpdate() becomes save() if id value in the object matches with the unsaved value attribute saveOrUpdate becomes save() else it becomes update().

Difference between sequence and identity in SQL Server
 
05:29
sql server identity vs sequence In this video we will discuss the difference between SEQUENCE and IDENTITY in SQL Server This is continuation to Part 134. Please watch Part 134 from SQL Server tutorial before proceeding. Sequence object is similar to the Identity property, in the sense that it generates sequence of numeric values in an ascending order just like the identity property. However there are several differences between the 2 which we will discuss in this video. Identity property is a table column property meaning it is tied to the table, where as the sequence is a user-defined database object and is not tied to any specific table meaning it's value can be shared by multiple tables. Example : Identity property tied to the Id column of the Employees table. CREATE TABLE Employees ( Id INT PRIMARY KEY IDENTITY(1,1), Name NVARCHAR(50), Gender NVARCHAR(10) ) Example : Sequence object not tied to any specific table CREATE SEQUENCE [dbo].[SequenceObject] AS INT START WITH 1 INCREMENT BY 1 This means the above sequence object can be used with any table. Example : Sharing sequence object value with multiple tables. Step 1 : Create Customers and Users tables CREATE TABLE Customers ( Id INT PRIMARY KEY, Name NVARCHAR(50), Gender NVARCHAR(10) ) GO CREATE TABLE Users ( Id INT PRIMARY KEY, Name NVARCHAR(50), Gender NVARCHAR(10) ) GO Step 2 : Insert 2 rows into Customers table and 3 rows into Users table. Notice the same sequence object is generating the ID values for both the tables. INSERT INTO Customers VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Ben', 'Male') INSERT INTO Customers VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Sara', 'Female') INSERT INTO Users VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Tom', 'Male') INSERT INTO Users VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Pam', 'Female') INSERT INTO Users VALUES (NEXT VALUE for [dbo].[SequenceObject], 'David', 'Male') GO Step 3 : Query the tables SELECT * FROM Customers SELECT * FROM Users GO Output : Notice the same sequence object has generated the values for ID columns in both the tables To generate the next identity value, a row has to be inserted into the table, where as with sequence object there is no need to insert a row into the table to generate the next sequence value. You can use NEXT VALUE FOR clause to generate the next sequence value. Example : Generating Identity value by inserting a row into the table INSERT INTO Employees VALUES ('Todd', 'Male') Example : Generating the next sequence value using NEXT VALUE FOR clause. SELECT NEXT VALUE FOR [dbo].[SequenceObject] Maximum value for the identity property cannot be specified. The maximum value will be the maximum value of the correspoding column data type. With the sequence object you can use the MAXVALUE option to specify the maximum value. If the MAXVALUE option is not specified for the sequence object, then the maximum value will be the maximum value of it's data type. Example : Specifying maximum value for the sequence object using the MAXVALUE option CREATE SEQUENCE [dbo].[SequenceObject] START WITH 1 INCREMENT BY 1 MAXVALUE 5 CYCLE option of the Sequence object can be used to specify whether the sequence should restart automatically when the max value (for incrementing sequence object) or min value (for decrementing sequence object) is reached, where as with the Identity property we don't have any such option to automatically restart the identity values. Example : Specifying the CYCLE option of the Sequence object, so the sequence will restart automatically when the max value is exceeded CREATE SEQUENCE [dbo].[SequenceObject] START WITH 1 INCREMENT BY 1 MINVALUE 1 MAXVALUE 5 CYCLE Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-sequence-and.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-sequence-and_27.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

Object relational Mapping (ORM) is a way to virtually map Java objects with relational database to aid in object-oriented programming, and Hibernate is one of the most popular ORM framework on the market. With Visual Paradigm NetBeans Integration, you can have an all-in-one modeling plugin for your NetBeans. You can design database with ERD tool, and design system with UML diagrams. You can also generate database and executable hibernate source code out of your diagrams. In this video we will show you how to define your object relational mapping by first creating an ERD, then generate class diagram, database as well as hibernate source code. The video will also show you how you can work with the generated hibernate source code to manipulate your database. Visual Paradigm Standard Edition, NetBeans 8.0.1 and Microsoft SQL Server will be used during the demonstration.

MySQL 15 - Auto Increment (AUTO_INCREMENT)
 
05:19
If you are using surrogate keys, every row is going to need to have a unique value for this column. The easiest way to do this is to just count upwards. The downside is that every time you insert data you are going to have to know what number to use. Fortunately, there is an easier way, with what is known as an AUTO_INCREMENT column. An AUTO_INCREMENT column is a column in a table that automatically counts upwards. If we set the PK column as an AUTO_INCREMENT column, we do not have to worry about keeping track of the numbers we've already used. Now, you can only have one AUTO_INCREMENT column per table, and you can only have one primary key per table. AUTO_INCREMENT has to be used on a primary key or a unique index. It makes sense to make the primary key column the AUTO_INCREMENT column, but you can create any other column as the AUTO_INCREMENT column as long as it has a UNIQUE index. So, for example, if you wanted to use a natural primary key but wanted to have a column that auto increments, you could do that by making the incrementing column UNIQUE. Now, the AUTO_INCREMENT does not force the data to never change. It is important to understand that the concept of surrogate and natural keys is foreign to the database. The database does not care what kind of key you use, as long as the qualifications are met. There are no keywords that say surrogate. There are no keywords that say natural. These are categories that we've made to help us better communicate about primary keys. An interesting thing you can do with primary keys is that you can make a combination of columns the primary key. This is important when more than one column is required to make something unique. In an intermediary table, instead of having an association ID, we can have the combination of two rows as the primary key. This is known as either a compound or composite primary key. In the situation of using natural keys, composite keys are more common. For example, you could have a shopping website that allows multiple people from the same household to use a certain coupon you sent out. In this situation, you could use the address and the person's name as the natural primary key. How do we reference primary keys? This requires what is known as a foreign key, which we will discuss in the next video. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support 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!)
