IN VS EXISTS VS JOIN, performance
 
05:04
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.

Merge Statement in Oracle SQL with Example (UPDATE/DELETE or INSERT)
 
15:04
This video demonstrates how to write a Merge Statement in oracle sql, how it is useful in doing a conditional update or delete or both of them when the condition between the target table and source table is evaluated to true, and how we can insert the record into the target table when condition is evaluated to false. The video also shows the use of UPDATE, DELETE and INSERT with Merge, and also the various possible ways to use a Merge statement!!!

Merge: Databases for Developers #17
 
05:26
Sometimes when adding rows to your database need update-if-exists, insert-if-not-exists logic. Aka an upsert. You could write this as separate update and insert statements. But there is an easier way: Merge! Watch this video for an overview of how merge works. Further reading: Merge documentation: https://docs.oracle.com/en/database/oracle/oracle-database/18/sqlrf/MERGE.html Delete rows not in the source using merge: https://technology.amis.nl/2006/10/14/have-merge-remove-records-from-target-that-are-not-in-the-source-oracle-10g/ Take the course: https://devgym.oracle.com/pls/apex/dg/class/databases-for-developers-next-level.html Need help with SQL?

UPDATE STATEMENT WITH JOIN IN ORACLE SQL
 
07:18
This video demonstrates how user can update data of a particular table(t1), based on the join condition with other table(t2). So it would be a easy way to ditch the for-loop, and check for the condition every time. What was to be achieved from the for-loop can be achieved with a single simple update statement. A simple trick to update data in table based on some conditional data in some another table, would help you to increase the performance of your code massively. For ex : UPDATE TABLE1 t1 SET COL1 = (SELECT COL FROM TABLE2 t2 where t1.col = t2.col);

How to find duplicate records in table sql

There are various times when we need to find duplicate records in SQL Server. It is possible to find duplicates using DISTINCT, ROW NUMBER as well as the GROUP BY approach. ------------- May be you like this -------------- umbraco playlist : https://www.youtube.com/watch?v=zoefdruzmGE&list=PLv0T7WlllnSnYRedhwL8x-atkVxrSdd3m Angularjs playlist : https://www.youtube.com/watch?v=KXjD1RiAz1U&list=PLv0T7WlllnSkCfNftTNY8tWqCFWT0sIMd jquery playlist : https://www.youtube.com/watch?v=jVncasz_iyw&list=PLv0T7WlllnSkkNahiiWu_GMXq49X5ccfe F Wcf playlist : https://www.youtube.com/watch?v=NB4k0RC6vl0&list=PLv0T7WlllnSmcGHacEQnLgKvitcJEsSl6 c# playlist: https://www.youtube.com/watch?v=ZrP0NKbsr8s&list=PLv0T7WlllnSl9pZWMaMGsyoAmqZtW4gM0 Duplicate records can create problems sometimes when displaying reports or performing a Multiple Insert update. Finding duplicate records in a database needs further investigation. In some cases, duplicate records are positive, but it all depends on the data and the database design as well. For example, if a customer has ordered the same product twice on the same date with the the same shipping and billing address, then this may result in a duplicate record.

Oracle SQL Tutorial 22 - Why Primary Keys Shouldn't Change
 
07:14
In the last video I mentioned that with our database design it is important to make sure that nobody tries to update a user's username. What happens if they do? Nothing horrible, Oracle will just throw an error. That's not such a big deal, but if you are hoping to make some kind of application that allows someone to change their username, this is not the best set up. Why? If you look at the projects table, we have a foreign key that references the username. Let's assume for a moment that Oracle allows you to do anything with your data. That means that if a user updates their username, there will be projects created by users that don't exist. Or a user could change their name to the previous owner. To fix this problem, we would need something such as an ON UPDATE CASCADE command for our foreign key. That would mean that if the user updated their username, the columns that reference that username would also update to the new value. This exists in some database management systems, but this does not exist in Oracle at the time of this video. How do we get around this problem? I'm sure we could conjure up something to allow us to update the username, but the easiest solution is to reference the user_id instead of the username. That way, when the username is updated, nothing changes inside of the foreign key. As a general rule, primary keys should never change. Foreign keys CAN change, but they should not change because a primary key changed. So, if we did happen to use a username as a column, it would be frowned upon if the username had to change because the column it references changes. However, it would be acceptable to change the foreign key if we needed to point to a new entity in the users table. Even if a username is never intended to change, these complications bother a lot of people. You can mitigate these problems by only referencing surrogate keys in foreign keys. This has the downside though that when you retrieve the data, you are going to have to do more work to make the data readable. For example, we had a table that was called project_users. It is essentially a table that says what users are part of what projects. We could have the foreign keys reference the project's name and the user's username. Then when you could say SELECT * FROM project_users. The data would be completely readable without doing anything. If you switch to only referencing surrogate primary keys, you will have a bunch of random numbers that don't mean anything and will have to be joined with other tables…which is really super frustrating when later you have to join a thousand tables to read anything. Which side do you prefer? Pick a side. Choose wisely.

This means a given student can be enrolled into many courses and a given course can have many students enrolled. Below is the question asked in an interview for SQL Server Developer role. Write a SQL script to insert data into StudentCourses table. Here are the rules that your script should follow. 1. There will be 2 inputs for the script Student Name - The name of the student who wants to enroll into a course Course Name - The name of the course the student wants to enroll into 2. If the student is already in the Students table, then use that existing Student Id. If the student is not already in the Students table, then a row for that student must be inserted into the Students table, and use that new student id. 3. Along the same lines, if the course is already in the Courses table, then use that existing Course Id. If the course is not already in the Courses table, then a row for that course must be inserted into the Courses table, and use that new course id. 4. There should be no duplicate student course enrollments, i.e a given student must not be enrolled in the same course twice. For example, Tom must not be enrolled in C# course twice. Answer : To avoid duplicate student course enrollments create a composite primary key on StudentId and CourseId columns in StudentCourses table. With this composite primary key in place, if someone tries to enroll the same student in the same course again we get violation of primary key constraint error. Alter table StudentCourses Add Constraint PK_StudentCourses Primary Key Clustered (CourseId, StudentId) Here is the SQL script that inserts data into the 3 tables as expected Declare @StudentName nvarchar(50) = 'Sam' Declare @CourseName nvarchar(50) = 'SQL Server' Declare @StudentId int Declare @CourseId int -- If the student already exists, use the existing student ID Select @StudentId = Id from Students where StudentName = @StudentName -- If the course already exists, use the existing course ID Select @CourseId = Id from Courses where CourseName = @CourseName -- If the student does not exist in the Students table If (@StudentId is null) Begin -- Insert the student Insert into Students values(@StudentName) -- Get the Id of the student Select @StudentId = SCOPE_IDENTITY() End -- If the course does not exist in the Courses table If (@CourseId is null) Begin -- Insert the course Insert into Courses values(@CourseName) -- Get the Id of the course Select @CourseId = SCOPE_IDENTITY() End -- Insert StudentId & CourseId in StudentCourses table Insert into StudentCourses values(@StudentId, @CourseId) If required, we can very easily convert this into a stored procedure as shown below. Create procedure spInsertIntoStudentCourses @StudentName nvarchar(50), @CourseName nvarchar(50) as Begin Declare @StudentId int Declare @CourseId int Select @StudentId = Id from Students where StudentName = @StudentName Select @CourseId = Id from Courses where CourseName = @CourseName If (@StudentId is null) Begin Insert into Students values(@StudentName) Select @StudentId = SCOPE_IDENTITY() End If (@CourseId is null) Begin Insert into Courses values(@CourseName) Select @CourseId = SCOPE_IDENTITY() End Insert into StudentCourses values(@StudentId, @CourseId) End Use the following statement to execute the stored procedure Execute spInsertIntoStudentCourses 'Tom','C#'

DYNAMIC SQL WITH EXECUTE IMMEDIATE IN ORACLE PL/SQL WITH EXAMPLE
 
21:53
The audio and video now synced. Ever tried creating a table inside a PL SQL block, or a function or a procedure? If yes, then you would know that it would raise an error, as DDL statements are not allowed inside a PL/SQL Block. So the solution to such a case, where you want to generate tables, or sequences or want to execute any DDL statement on the fly, then use synamic sql. Dynamic SQL statment will allow you to create state statements on the fly and then you can execute them using the execute immediate statement. This video tutorial demonstrates on this topic of using synamic sql with execute immediate in a PL/SQL block.

SQL Server 12 - Referential Integrity
 
05:15
The concept of referential integrity is protecting relationships in our database. As a reminder, a relationship is when we have a foreign key reference another column. This column is usually the primary key of another table. This is a foreign key connection. If by any chance we establish a database structure where a table references another table, but we don't enforce this any way, the data in the table that is being referenced could be deleted, but the reference would still exist. If this happened, we would be breaking our referential integrity. We protect this by using referential constraints. A referential constraint tells the database that there is a connection between the two columns. This will allow you to configure what happens when the table being referenced gets updated or deleted. Another important thing to protecting referential integrity it to design the database in the correct way. This requires in depth knowledge of different types of relationships. How do you know when you need to put things in separate tables? We discussed all of the relationship possibilities in previous videos. In summary, relationships are not just something we assume… They are objectively defined so that the database knows they exists. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

You can use it in an INSERT statement, an UPDATE statement, or with a variable in PL/SQL. The syntax of the EMPTY_BLOB function is: EMPTY_BLOB That’s it - no parameters. Why would you set a BLOB value to empty? It means you have initialised it but not given it a value. It’s good to know this function exists if you ever need to use it.

How to Resolve Oracle SQL Parent Key Not Found (ORA-02291)
 
05:49
In this video, we’ll explain what the ORA-02291 “parent key not found” error is, see an example, and look at how to resolve it. This error usually happens when we try to insert data into a table. It looks like this: Error is: ORA-02291: integrity constraint (constraint_name) violated - parent key not found So what does this error mean? It means we’re trying to insert data into a child table, and there is no related record in the parent table. If a foreign key has been set up to enforce this relationship, there needs to be a parent to insert a child that refers to it. Watch the video to see an example of this error as well as how to resolve it. For more information on Oracle SQL, refer to the Database Star website here: https://www.databasestar.com/

How to INSERT data into table in MySQL?
 
02:44
MySQL INSERT MySQL INSERT statement is used to insert data in MySQL table within the database. We can insert single or multiple records using a single query in MySQL. Syntax: The SQL INSERT INTO command is used to insert data in MySQL table.

Lesson - 72 : Hibernate - Most important Differences Between Methods
 
11:00
Hibernate – Most important Differences Between Methods : Q)what is the difference between load() and get() methods? load() method performs lazy loading , but get() method performs early loading. If a given id is not exist in the database then load() methodthrows ObjectNotFound Exception, but get() method returns null. Q) Difference between update() and merge()? Update and merge methods are used to convert an object state from detached to persistent. Detached state means the state obtained by an object, after coming out of a session cache. In hibernate a session cache can allow only one object of a pojo class with the same identifier (id). If another one is going to enter into the cache with the same identifier then hibernate throes an exception. Q) Difference between save() and saveOrUpdate()? Whenever save() method is called then hibernate checks the id of the object is not available in database or not. If not available then the object will be solved, otherwise an exception will be thrown. Whenever saveOrUpdate() method is called, then hibernate performs save operation if the id does not exist in the database or performs update operation if id exist in database, but exception will not be thrown. Q) Difference between save() and Persist()? Save() method return type is serializable and persist() method return type is a void. If you call save() then it will save the object in database and also it returns the id of that object back to java application. But if you call persist() then it will save the object in database, but it does not return the id of that object. When generator class is other than assigned then id of the object will be generated by hibernate. If you want to get the id generated by the hibernate then we can use save method. In case of generator classis assigned , we manually assign id for the object. so we can call persist() in this case. In java if a method returns some value then it is optional to store return value into some variable. So when save() is called, it is optional to store the id returned by the method into some serializable object. Q) Differences between openSession and getCurrentSession? Session object : It always create new Session object Session object : It creates a new Session if not exists , else use same session which is in current hibernate context Flush and close : You need to explicitly flush and close session objects Flush and close : You do not need to flush and close session objects, it will be automatically taken care by Hibernate internally Performance : In single threaded environment , It is slower than getCurrentSession Performance : In single threaded environment , It is faster than getOpenSession Configuration : You do not need to configure any property to call this method Configuration : You need to configure additional property “hibernate.current_session_context_class” to call getCurrentSession method, otherwise it will throw exceptions.
