This video is to understand how we can update a column of a table, based on the data present on the other table, and both the tables having a common column. Its a complicated update statement that can be used to update with different conditions.

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!!!

Learn about using UPDATE statement in SQL. As the name suggests UPDATE statement is used to update the data rows in a table. The UPDATE statement can update one or multiple column values in single SQL statement. WHERE clause is used to specify the data row to be updated. UPDATE statement without WHERE clause will update all the data rows in the table. Any existing data rows or records in target table remain unaffected. Here are the examples UPDATE statements, UPDATE tablename SET column1 = newvalue; UPDATE tablename SET column1 = newvalue1, column2 = newvalue2 WHERE columnid = 3; Select the "school" database, "USE school;" Run a simple SQL statement to display all the data rows in students table using SQL statement, "SELECT * FROM students;" Here in this result set, take a look at studentid 1. Suppose we have accidentally added this student record under class first instead of second. And now we are going to update this row to change the class value from 'First' to 'Second'. We will use the SQL statement, "UPDATE students SET class = 'Second' WHERE studentid = 1;" Press enter to execute the statement and display all the data rows in 'students' table, "SELECT * FROM students;" And sure enough the class value for studentid 1 is changed from 'First' to 'Second'.

How To Insert,update,delete,join Data into a Table Using SQL Developer tool In this topic, you learn to add objects to the Query Builder interface and then create a query based on those objects. In this section, you create a query based on the EMPLOYEES and DEPARTMENTS tables. You will generate output that shows per department name, the employees who work in that department. Perform the following steps to add the EMPLOYEES table to the Query Builder. 1 . Select the Query Builder tab to open Query Builder window. 2 . Drag and drop the EMPLOYEES table from the Connections navigator to the Query Builder window. 3 . Drag and drop the DEPARTMENTS table object over to the Query Builder window, so that the two table objects are displayed in the Query Builder window. Because there are two relationships defined between the EMPLOYEES and DEPARTMENTS tables, you see two lines between the tables identifying the columns that are linked together through foreign key constraints. The two relationships are defined as: The MANAGER_ID in the DEPARTMENTS table must be a value of the EMPLOYEE_ID in the EMPLOYEES table (managers must exist as employees). The DEPARTMENT_ID in the EMPLOYEES table must be a value of the DEPARTMENT_ID in the DEPARTMENTS table (an employee's department must exist in the DEPARTMENTS table, or be null). 4 . Next, you select the columns that you want to see in the report. In the EMPLOYEES table, check the FIRST_NAME, LAST_NAME, JOB_ID, SALARY, and DEPARTMENT_ID columns. As you select these columns, note that they are added in the order that you select them into the window below the table objects. In the DEPARTMENTS table, check the DEPARTMENT_NAME column. 5 . Click Run .

This means we no longer have to use multiple statements for performing Insert, Update and Delete. With merge statement we require 2 tables 1. Source Table - Contains the changes that needs to be applied to the target table 2. Target Table - The table that require changes (Inserts, Updates and Deletes) The merge statement joins the target table to the source table by using a common column in both the tables. Based on how the rows match up as a result of the join, we can then perform insert, update, and delete on the target table. Merge statement syntax MERGE [TARGET] AS T USING [SOURCE] AS S ON [JOIN_CONDITIONS] WHEN MATCHED THEN [UPDATE STATEMENT] WHEN NOT MATCHED BY TARGET THEN [INSERT STATEMENT] WHEN NOT MATCHED BY SOURCE THEN [DELETE STATEMENT] Example 1 : In the example below, INSERT, UPDATE and DELETE are all performed in one statement 1. When matching rows are found, StudentTarget table is UPDATED (i.e WHEN MATCHED) 2. When the rows are present in StudentSource table but not in StudentTarget table those rows are INSERTED into StudentTarget table (i.e WHEN NOT MATCHED BY TARGET) 3. When the rows are present in StudentTarget table but not in StudentSource table those rows are DELETED from StudentTarget table (i.e WHEN NOT MATCHED BY SOURCE) Create table StudentSource ( ID int primary key, Name nvarchar(20) ) GO Insert into StudentSource values (1, 'Mike') Insert into StudentSource values (2, 'Sara') GO Create table StudentTarget ( ID int primary key, Name nvarchar(20) ) GO Insert into StudentTarget values (1, 'Mike M') Insert into StudentTarget values (3, 'John') GO MERGE INTO StudentTarget AS T USING StudentSource AS S ON T.ID = S.ID WHEN MATCHED THEN UPDATE SET T.NAME = S.NAME WHEN NOT MATCHED BY TARGET THEN INSERT (ID, NAME) VALUES(S.ID, S.NAME) WHEN NOT MATCHED BY SOURCE THEN DELETE; Please Note : Merge statement should end with a semicolon, otherwise you would get an error stating - A MERGE statement must be terminated by a semi-colon (;) In real time we mostly perform INSERTS and UPDATES. The rows that are present in target table but not in source table are usually not deleted from the target table. Example 2 : In the example below, only INSERT and UPDATE is performed. We are not deleting the rows that are present in the target table but not in the source table. Truncate table StudentSource Truncate table StudentTarget GO Insert into StudentSource values (1, 'Mike') Insert into StudentSource values (2, 'Sara') GO Insert into StudentTarget values (1, 'Mike M') Insert into StudentTarget values (3, 'John') GO MERGE INTO StudentTarget AS T USING StudentSource AS S ON T.ID = S.ID WHEN MATCHED THEN UPDATE SET T.NAME = S.NAME WHEN NOT MATCHED BY TARGET THEN INSERT (ID, NAME) VALUES(S.ID, S.NAME);

In this video I use the UPDATE command to change existing data within a table. When using the UPDATE command you also need to use the keyword SET to choose the field column you wish to change and also a WHERE statement to choose the individual record that needs changed. The command I used is: UPDATE BOOKS SET BINDING = 'P' WHERE BOOK_ID = '11'; This video is part of a series of videos with the purpose of learning the SQL language.

Welcome everyone! Something you need to consider when you are creating foreign keys is what happens if you delete the parent? As a reminder, the parent is the row that has the value you are referencing in the row that has a foreign key. Why is this something important to consider? It's important because foreign keys need to protect us from two primary things, unacceptable INSERT statements, and unacceptable DELETE statements. Let's see what happens when we try to insert incorrect data into the table with the foreign key: INSERT INTO projects VALUES (1, 'Update website homepage', 'CalebCurry') The response tells us plainly that there is no such user in the users table. So this works correctly. Deleting data on the other hand works a bit differently because the database does not know what you want to do with the child row when you delete the parent from the parent table. By default, we will get an error message that prevents the parent from being deleted, but there are some other options. How do we configure this? This is where the ON DELETE statement comes in. We add the keywords ON DELETE right after the foreign key and then we can give it the option of CASCADE or SET NULL. CASCADE means that if we delete the parent, we are also going to delete the child. In our situation what that means is that if somebody creates a project in our project table and then that persons account gets deleted, all of the projects he owns will also be deleted. CASCADE: CREATE TABLE projects( project_id NUMBER, Project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL, CONSTRAINT projects_pk PRIMARY KEY (project_id), CONSTRAINT projects_users_fk FOREIGN KEY (creator) REFERENCES users (username) ON DELETE CASCADE ) SET NULL will take the value in the child table and get rid of it. What you are left with is NULL. This means that we have an orphaned child. The first thought you might have is that it is a bad thing to have an orphaned child, but in databases that is not always so. In our application if we had it set to SET NULL, when a user account gets deleted the projects would remain in existence they would just lack a creator. This might be a good thing if you are concerned about the long term survival of a project, this might be the route you want to go. It ultimately depends on the application purpose. If you don't like CASCADE or SET NULL, you can leave the entire ON DELETE statement and just have Oracle throw an error when a parent is deleted. As for us, we are going to use ON DELETE CASCADE. We need to use this with extreme caution. If you are not careful, someday you will run a delete a row and that will cascade through you database deleting a bunch of stuff you didn't want to delete. Stuff happens, so make sure you back up your database every once in eternity. Now, in the last video we started with a database design that had three tables. We've only created two in this video. In the next video we are going to create the next one, which is a little special. Then we'll finish things up by adding some indexes. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me on Patreon! 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!)

We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it
