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 identity column

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

SQL Tutorial - Window Functions - Lag and Lead
Another video brought to you by BeardedDev, bringing you tutorials on Business Intelligence, SQL Programming and Data Analysis. In this video I talk about using Lag and Lead in Windows Functions. This video covers the requirements to pass the exam: If you would like to follow along with the tutorial please run the SQL below: IF OBJECT_ID(N'dbo.Sales', N'U') IS NOT NULL DROP TABLE dbo.Sales; GO CREATE TABLE dbo.Sales ( Sales_Id INT NOT NULL IDENTITY(1, 1) CONSTRAINT PK_Sales_Sales_Id PRIMARY KEY , Sales_Customer_Id INT NOT NULL , Sales_Date DATETIME2 NOT NULL , Sales_Amount DECIMAL (16, 2) NOT NULL ) INSERT INTO dbo.Sales (Sales_Customer_Id, Sales_Date, Sales_Amount) VALUES (1, '20180102', 54.99) , (1, '20180103', 72.99) , (1, '20180104', 34.99) , (1, '20180115', 29.99) , (1, '20180121', 67.00) Lag and Lead are useful for performing trend analysis, in the example I show how we can display a customer spending trend. Lag will show the previous value. Lead will show the next value. Lag and Lead accept multiple parameters as demonstrated in the video: LAG([Column], [Offset], [Value if NULL]) The example of LAG and LEAD in the video can be shown by executing the below SQL query: SELECT Sales_Customer_Id , Sales_Date , LAG(Sales_Amount, 2, 0) OVER(PARTITION BY Sales_Customer_Id ORDER BY Sales_Date) AS PrevValue , Sales_Amount , LEAD(Sales_Amount, 2, 0) OVER(PARTITION BY Sales_Customer_Id ORDER BY Sales_Date) AS NextValue FROM dbo.Sales Please feel free to post comments.

MySQL 15 - Auto Increment (AUTO_INCREMENT)
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!)
