PL/SQL tutorial : Trigger in Oracle Database 11g Complete guide
 
26:21
Learn in depth about trigger in oracle database 11g, and usage of trigger in Database, different types of trigger with syntax for various events along with writing advance trigger and capturing all details regarding authentication. Explained Instead of trigger. Trigger in Oracle, Trigger in PL/SQL, Oracle Trigger, PL/SQL Trigger, What is Trigger in pl/sql, How to use Trigger in pl/sql, How to write a Trigger in oracle, How to design Trigger in pl/sql, DDL trigger, DML trigger, Instead of trigger, Compound trigger, Logon trigger, Introduction to Triggers You can write triggers that fire whenever one of the following operations occurs: DML statements (INSERT, UPDATE, DELETE) on a particular table or view, issued by any user DDL statements (CREATE or ALTER primarily) issued either by a particular schema/user or by any schema/user in the database Database events, such as logon/logoff, errors, or startup/shutdown, also issued either by a particular schema/user or by any schema/user in the database Triggers are similar to stored procedures. A trigger stored in the database can include SQL and PL/SQL or Java statements to run as a unit and can invoke stored procedures. However, procedures and triggers differ in the way that they are invoked. A procedure is explicitly run by a user, application, or trigger. Triggers are implicitly fired by Oracle when a triggering event occurs, no matter which user is connected or which application is being used. How Triggers Are Used Triggers supplement the standard capabilities of Oracle to provide a highly customized database management system. For example, a trigger can restrict DML operations against a table to those issued during regular business hours. You can also use triggers to: Automatically generate derived column values Prevent invalid transactions Enforce complex security authorizations Enforce referential integrity across nodes in a distributed database Enforce complex business rules Provide transparent event logging Provide auditing Maintain synchronous table replicates Gather statistics on table access Modify table data when DML statements are issued against views Publish information about database events, user events, and SQL statements to subscribing applications Linkedin: https://www.linkedin.com/in/aditya-kumar-roy-b3673368/ Facebook: https://www.facebook.com/SpecializeAutomation/

In case you miss the SQL functions intro video you can find the link in the description below. First let's see what these functions are. Upper (): This function takes a parameter converts it into uppercase and returns the new string. Initcap (): this function also takes parameter and converts the initial letter of or parameter into uppercase and returns the new string. Lower (): This function takes a parameter converts it into lowercase and returns the new string. Ok let's do some practical For this practical we will be using 2 tables First is dual table Which is a dummy table provided by oracle? And I have created another table again by the name of example. This will be our second table. Let's start with SQL function upper ( ); SELECT upper('hello world') FROM dual; As you can see I have used "hello world" completely in lowercase as parameter to SQL upper function. Execute it. Here, our result has given us a completely new hello world string which is in uppercase. Similarly you can also use SQL upper function to perform other DML Let's try This time we will work on our second table EXAMPLE; insert into example values (upper('manish')); first parentheses for values and second for SQL function upper. Let's check the result. As you can see here inserted value is in upper case. Lets compare it with simple insert query Insert into example values ('manish'); Execute it, i think now it's clear that when we perform simple insert DML the inserted value will be the same you provide. Similarly let's try SQL function initcap(); SELECT initcap('hello world') FROM dual; As you see here in result the initial letters of string hello world are in uppercase. Let's do the insert query insert into example values (initcap('hello world')); initial letters of string also are in uppercase. Let's try SQL function lower(); This time we have to write our hello world in all caps. SELECT lower('HELLO WORLD') FROM dual; Execute String totally in lower case. Similarly you can user SQL function lower in other DML like insert and all.

09 MySQL Tutorial for Beginners: LIKE + REGEXP Operators, Regular Expressions
 
09:12
You use the LIKE operator to retrieve rows that match a string pattern. The Mask for a LIKE phrase can contain special symbols called "wildcards". Masks aren't case-sensitive. In contrast to the LIKE operator, the REGEXP operator allows you to create complex string patterns known as regular expressions. The mask for a REGEXP phrase can contain special characters and constructs like: - the "caret" (^) symbol matches the pattern to the beginning of the value being tested. - The "dollar sign" ($) symbol matches the pattern to the end of the value being tested. - The "pipe" (|) symbol separates two string patterns and matches either one. - "Square brackets" [] are used to specify multiple values. lf you use the NOT keyword, only those rows with values that don't match the string pattern are included in the result set.

This video demonstrates the performance effects of using an exists clause instead of an IN clause, also it shows how we can update a simple sub query having an IN clause with an EXISTS or JOIN statement. It also shows that joining would consider the null data, where as an IN clause would neglect null values.

Learn Store Procedure in SQL in Hindi tutorial for beginners
 
08:45
Stored Procedure: Stored Procedure in SQL Server can be defined as the set of logical group of SQL statements which are grouped to perform a specific task. There are many benefits of using a stored procedure. The main benefit of using a stored procedure is that it increases the performance of the database.The other benefits of using the Stored Procedure are given below. Benefits of Using the Stored Procedure One of the main benefits of using the Stored procedure is that it reduces the amount of information sent to the database server. It can become a more important benefit when the bandwidth of the network is less. Since if we send the SQL query (statement) which is executing in a loop to the server through network and the network gets disconnected, then the execution of the SQL statement doesn't return the expected results, if the SQL query is not used between Transaction statement and rollback statement is not used. Compilation step is required only once when the stored procedure is created. Then after it does not require recompilation before executing unless it is modified and reutilizes the same execution plan whereas the SQL statements need to be compiled every time whenever it is sent for execution even if we send the same SQL statement every time. It helps in re usability of the SQL code because it can be used by multiple users and by multiple clients since we need to just call the stored procedure instead of writing the same SQL statement every time. It helps in reducing the development time. Stored procedure is helpful in enhancing the security since we can grant permission to the user for executing the Stored procedure instead of giving permission on the tables used in the Stored procedure. Sometimes, it is useful to use the database for storing the business logic in the form of stored procedure since it makes it secure and if any change is needed in the business logic, then we may only need to make changes in the stored procedure and not in the files contained on the web server.

download mysql-connector.jar file https://goo.gl/ftjWmK if this video really helped you then you can help me out by Donatation me on PayPal paypal.me/Tarique1 For connecting java application with the mysql database, you need to follow 5 steps to perform database connectivity. In this example we are using MySql as the database. So we need to know following informations for the mysql database: Driver class: The driver class for the mysql database is com.mysql.jdbc.Driver. Connection URL: The connection URL for the mysql database is jdbc:mysql://localhost:3306/test where jdbc is the API, mysql is the database, localhost is the server name on which mysql is running, we may also use IP address, 3306 is the port number and test is the database name. We may use any database, in such case, you need to replace the test with your database name. Username: The default username for the mysql database is root. Password: The default password for the mysql database is ""(blank).Password is given by the user at the time of installing the mysql database. In this example, we are going to use "" as the password. Let's first create a table in the mysql database, but before creating table, we need to create database first. create database test; use test; create table tblogin(UserName varchar(10),Password varchar(40)); ----------------------------------- The above example will fetch all the records of tblogin table. To connect java application with the mysql database mysqlconnector.jar file is required to be loaded. download the jar file mysql-connector.jar Two ways to load the jar file: paste the mysqlconnector.jar file in jre/lib/ext folder set classpath 1) paste the mysqlconnector.jar file in JRE/lib/ext folder: Download the mysqlconnector.jar file. Go to jre/lib/ext folder and paste the jar file here. 2) set classpath: There are two ways to set the classpath: temporary permanent How to set the temporary classpath open command prompt and write: C: set classpath=c:\folder\mysql-connector-java-5.0.8-bin.jar;.; How to set the permanent classpath Go to environment variable then click on new tab.

We will be using Countries table in this example. SQL to create the table Create Table Countries ( Country nvarchar(50), City nvarchar(50) ) GO Insert into Countries values ('USA','New York') Insert into Countries values ('USA','Houston') Insert into Countries values ('USA','Dallas') Insert into Countries values ('India','Hyderabad') Insert into Countries values ('India','Bangalore') Insert into Countries values ('India','New Delhi') Insert into Countries values ('UK','London') Insert into Countries values ('UK','Birmingham') Insert into Countries values ('UK','Manchester') Here is the interview question. Write a sql query to transpose rows to columns. Using PIVOT operator we can very easily transform rows to columns. Select Country, City1, City2, City3 From ( Select Country, City, 'City'+ cast(row_number() over(partition by Country order by Country) as varchar(10)) ColumnSequence from Countries ) Temp pivot ( max(City) for ColumnSequence in (City1, City2, City3) ) Piv

R tutorial: connecting to a database
 
03:38
Learn more about connecting to databases with R: https://www.datacamp.com/courses/importing-data-in-r-part-2 Welcome to part two of importing data in R! The previous course dealt with accessing data stored in flat files or excel files. In a professional setting, you'll also encounter data stored in relational databases. In this video, I'll briefly talk about what a relational database is and then I'll explain how you can connect to it. In the next video, I'll explain how you can import data from it! So, what's a relational database? There's no better way to show this than with an example. Take this database, called company. It contains three tables, employees, products and sales. Like a flat file, information is displayed in a table format. The employees table has 5 records and three fields, namely id, name and started_at. The id here serves as a unique key for each row or record. Next, the products table contains the details on four products. We're dealing with data from a telecom company that's selling both with and without a contract. Also here, each product has an identifier. Finally, there's the sales table. It lists what products were sold by who, when and for what price. Notice here that the ids in employee_id and product_id correspond to the ids that you can find in the employees and products table respectively. The third sale for example, was done by the employee with id 6, so Julie. She sold the product with id 9, so the Biz Unlimited contract. These relations make this database very powerful. You only store all necessary information once in nicely separated tables, but can connect the dots between different records to model what's happening. How the data in a relational database is stored and shuffled around when you make adaptations, depends on the so-called database management system, or DBMS you're using. Open-source implementations such as MySQL, postgreSQL and SQLite are very popular, but there are also proprietary implementations such as Oracle Database and Microsoft SQL server. Practically all of these implementations use SQL, or sequel, as the language for querying and maintaining the database. SQL stands for Structured Query Language. Depending on the type of database you want to connect to, you'll have to use different packages. Suppose the company database I introduced before is a MySQL database. This means you'll need the RMySQL package. For postgreSQL you'll need RpostgreSQL, for Oracle, you'll use ROracle and so on. How you interact with the database, so which R functions you use to access and manipulate the database, is specified in another R package called DBI. In more technical terms, DBI is an interface, and RMySQL is the implementation. Let's install the RMySQL package, which automatically installs the DBI package as well. Loading only the DBI package will be enough to get started. The first step is creating a connection to the remote MySQL database. You do this with dbConnect(), as follows. The first argument specifies the driver that you will use to connect to the MySQL database. It sure looks a bit strange, but the MySQL() function from the RMySQL package simply constructs a driver for us that dbConnect can use. Next, you have to specify the database name, where the database is hosted, through which port you want to connect, and finally the credentials to authenticate yourself. This is an actual database that we're hosting, so you can try these commands yourself! The result of the dbConnect call, con, is a DBI connection object. You'll need to pass this object to whatever function you're using to interact with the database. Before we do that, let's get familiar with this connection object in the exercises!

Streamed live on Jan 22, 2016 Talk by Max Mether here comes a time in each application's life when the needs on the database go beyond what a single server can provide. There are a multitude of ways you can scale your database server beyond just one server and this talk will look at different options. From standard replication and Galera clustering to sharding in the application layer and key based sharding, this talk will look at the different options, how to implement them with MariaDB and MySQL and look at benefits and disadvantages for each of them.

SQL Script to create Employees table Create table Employees ( ID int, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values (1, 'Mark', 'Hastings', 'Male', 60000) Insert into Employees values (1, 'Mark', 'Hastings', 'Male', 60000) Insert into Employees values (1, 'Mark', 'Hastings', 'Male', 60000) Insert into Employees values (2, 'Mary', 'Lambeth', 'Female', 30000) Insert into Employees values (2, 'Mary', 'Lambeth', 'Female', 30000) Insert into Employees values (3, 'Ben', 'Hoskins', 'Male', 70000) Insert into Employees values (3, 'Ben', 'Hoskins', 'Male', 70000) Insert into Employees values (3, 'Ben', 'Hoskins', 'Male', 70000) The delete query should delete all duplicate rows except one. Here is the SQL query that does the job. PARTITION BY divides the query result set into partitions.

Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/05/part-1-how-to-find-nth-highest-salary_17.html This is a very common SQL Server Interview Question. There are several ways of finding the nth highest salary. By the end of this video, we will be able to answer all the following questions as well. How to find nth highest salary in SQL Server using a Sub-Query How to find nth highest salary in SQL Server using a CTE How to find the 2nd, 3rd or 15th highest salary Let's use the following Employees table for this demo Use the following script to create Employees table Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) GO To find the highest salary it is straight forward. We can simply use the Max() function as shown below. Select Max(Salary) from Employees To get the second highest salary use a sub query along with Max() function as shown below. Select Max(Salary) from Employees where Salary [ (Select Max(Salary) from Employees) To find nth highest salary using Sub-Query SELECT TOP 1 SALARY FROM ( SELECT DISTINCT TOP N SALARY FROM EMPLOYEES ORDER BY SALARY DESC ) RESULT ORDER BY SALARY To find nth highest salary using CTE WITH RESULT AS ( SELECT SALARY, DENSE_RANK() OVER (ORDER BY SALARY DESC) AS DENSERANK FROM EMPLOYEES ) SELECT TOP 1 SALARY FROM RESULT WHERE DENSERANK = N To find 2nd highest salary we can use any of the above queries. Simple replace N with 2. Similarly, to find 3rd highest salary, simple replace N with 3. Please Note: On many of the websites, you may have seen that, the following query can be used to get the nth highest salary. The below query will only work if there are no duplicates. WITH RESULT AS ( SELECT SALARY, ROW_NUMBER() OVER (ORDER BY SALARY DESC) AS ROWNUMBER FROM EMPLOYEES ) SELECT SALARY FROM RESULT WHERE ROWNUMBER = 3
