Oracle tutorial : How to create Id with AUTO INCREMENT in Oracle PL SQL
 
08:43
Oracle tutorial: How to create Id with AUTO INCREMENT in Oracle oracle tutorial for beginners sequence in oracle identity key in sql In this Oracle tutorial , we can create an auto increment field using ‘sequence’ object that can be assigned as primary keys. Using Oracle ‘sequence’ object, you can generate new values for a column. An Oracle sequence is an object like a table or a stored procedure. Examples CREATE SEQUENCE SYSTEM.MYSEQ START WITH 1 MAXVALUE 999999999999999999999999999 MINVALUE 1 NOCYCLE CACHE 20 NOORDER; CREATE OR REPLACE TRIGGER TR_CITY BEFORE INSERT ON CITY FOR EACH ROW BEGIN SELECT LPAD(LTRIM(RTRIM(TO_CHAR(myseq.NEXTVAL))),10,'0') INTO :NEW.id FROM DUAL; END; / Subscribe on youtube: https://www.youtube.com/channel/UCpiyAesWNYOXSz5GPq8lbkA For more tutorial please visit #techquerypond https://techquerypond.wordpress.com https://twitter.com/techquerypond

Sequence object Introduced in SQL Server 2012 Generates sequence of numeric values in an ascending or descending order Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/sequence-object-in-sql-server-2012.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/sequence-object-in-sql-server-2012_26.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 Creating the Incrementing Sequence : The following code create a Sequence object that starts with 1 and increments by 1 CREATE SEQUENCE [dbo].[SequenceObject] AS INT START WITH 1 INCREMENT BY 1 Generating the Next Sequence Value : Now we have a sequence object created. To generate the sequence value use NEXT VALUE FOR clause SELECT NEXT VALUE FOR [dbo].[SequenceObject] Output : 1 Every time you execute the above query the sequence value will be incremented by 1. I executed the above query 5 times, so the current sequence value is 5. Retrieving the current sequence value : If you want to see what the current Sequence value before generating the next, use sys.sequences SELECT * FROM sys.sequences WHERE name = 'SequenceObject' Alter the Sequence object to reset the sequence value : ALTER SEQUENCE [SequenceObject] RESTART WITH 1 Select the next sequence value to make sure the value starts from 1 SELECT NEXT VALUE FOR [dbo].[SequenceObject] Using sequence value in an INSERT query : CREATE TABLE Employees ( Id INT PRIMARY KEY, Name NVARCHAR(50), Gender NVARCHAR(10) ) -- Generate and insert Sequence values INSERT INTO Employees VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Ben', 'Male') INSERT INTO Employees VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Sara', 'Female') -- Select the data from the table SELECT * FROM Employees Creating the decrementing Sequence : The following code create a Sequence object that starts with 100 and decrements by 1 CREATE SEQUENCE [dbo].[SequenceObject] AS INT START WITH 100 INCREMENT BY -1 Specifying MIN and MAX values for the sequence : Use the MINVALUE and MAXVALUE arguments to specify the MIN and MAX values respectively. Step 1 : Create the Sequence object CREATE SEQUENCE [dbo].[SequenceObject] START WITH 100 INCREMENT BY 10 MINVALUE 100 MAXVALUE 150 Step 2 : Retrieve the next sequence value. The sequence value starts at 100. Every time we call NEXT VALUE, the value will be incremented by 10. SELECT NEXT VALUE FOR [dbo].[SequenceObject] If you call NEXT VALUE, when the value reaches 150 (MAXVALUE), you will get the following error The sequence object 'SequenceObject' has reached its minimum or maximum value. Restart the sequence object to allow new values to be generated. Recycling Sequence values : When the sequence object has reached it's maximum value, and if you want to restart from the minimum value, set CYCLE option ALTER SEQUENCE [dbo].[SequenceObject] INCREMENT BY 10 MINVALUE 100 MAXVALUE 150 CYCLE At this point, whe the sequence object has reached it's maximum value, and if you ask for the NEXT VALUE, sequence object starts from the minimum value again which in this case is 100. To improve performance, the Sequence object values can be cached using the CACHE option. When the values are cached they are read from the memory instead of from the disk, which improves the performance. When the cache option is specified you can also specify the size of th cache , that is the number of values to cache. The following example, creates the sequence object with 10 values cached. When the 11th value is requested, the next 10 values will be cached again. CREATE SEQUENCE [dbo].[SequenceObject] START WITH 1 INCREMENT BY 1 CACHE 10 Using SQL Server Graphical User Interface (GUI) to create the sequence object : 1. Expand the database folder 2. Expand Programmability folder 3. Right click on Sequences folder 4. Select New Sequence Next video : Difference between SEQUENCE and IDENTITY in SQL Server

Oracle tutorial : Pseudo columns in Oracle PL SQL ( pseudocolumn ) oracle tutorial for beginners rownum in oracle This video will show you what is Pseudo columns in Oracle PL SQL. Pseudo columns are likes ROWNUM, ROENUM, ROWID, NEXTVAL,SYSDTAE , USER etc. pseudocolumn examples Oracle tutorial : Pseudo columns in oracle Oracle supports several special-purpose data elements that are not actually contained in a table, but are available for use in SQL statements. Here is a partial list of pseudo-columns in Oracle a)CURRVAL : When using Oracle SEQUENCE values, the pseudo-column CURRVAL returns the current value of the sequence. for example: schema.sequence_name.CURRVAL b)NEXTVAL :When using Oracle SEQUENCE values, the pseudo-column NEXTVAL returns the next value of the sequence and causes the sequence to increment by one. for example: schema.sequence_name.NEXTVAL c)ROWNUM:ROWNUM returns a number indicating the order in which a row was selected from a table. d)ROWID: ROWID returns the rowid (binary address) of a row in a database table. e)USER :This pseudo-column will always contain the Oracle username under which you are connected to the database. f)SYSDATE:This pseudo-column will contain the current date and time. This column is a standard Oracle DATE datatype. The value represents the current time on the server not the client.

Sequence vs AUTO_INCREMENT - Criação e Comportamento | Aula #02 | UpInside

Salve salve galera, Gustavo Web aqui com mais uma aula e agora a gente vai abordar o assunto SEQUENCE. https://www.upinside.com.br/blog/sequence-vs-auto-increment-criacao-e-comportamento Se você ainda não sabe do que se trata, é uma propriedade do PostgreSQL para ter o mesmo resultado do auto_increment de outros SGDB's de mercado como mysql e mariadb. Como trabalhamos com banco de dados relacional, uma das premissas que temos no nosso banco é que não podemos ter um registro com chave primária duplicada. Para manter a coesão e a integridade das informações, cada SGDB tem um tipo de comportamento. Nessa aula eu também uso dois links da documentação oficial do PostgreSQL, para acessar a página de como criar a SEQUENCE você pode clicar aqui, e para acessar sobre a propriedade DEFAULT/NEXTVAL clique aqui. https://www.postgresql.org/docs/current/static/sql-createsequence.html https://www.postgresql.org/docs/current/static/ddl-default.html Você vai notar nessa aula, que embora estamos trabalhando com outra plataforma de banco, conseguimos ter o mesmo resultado com pouquíssimo trabalho. Confira essa aula, pois ela é essencial para você modelar sua estrutura no PGSQL :) https://www.upinside.com.br/blog/sequence-vs-auto-increment-criacao-e-comportamento

create sequence in oracle | Sequences in Oracle in HINDI To create sequence in oracle, we have to use create sequence statement of oracle. This video of create sequence in oracle, will give you hands on practice about sequences in oracle. We have used screen capture option for making this video of sequences in oracle. The main objective of this video create sequence in oracle is to give the users a real hands on practice to use sequences in oracle. The language of the video is hindi, if you wish to watch this video in english, please suggest in comment section of this video. Oracle uses the concept of SEQUENCE to create numerical primary key values as we add rows of data into a table. Whereas numerical primary key population for MySQL and SQL Server is tied to individual tables, in Oracle the SEQUENCE construct is created separately and is not tied to an individual table. Hope this video of sequences in oracle, is helpful for you.

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://eepurl.com/-8qtH 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 - https://www.dreamhost.com/r.cgi?1487063 (The best web hosting for a cheap price!)
