Oracle SQL Tutorial 19 - ON DELETE (SET NULL and CASCADE)
 
05:59
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!)

SQL Null or Empty   How to Check for Null or Empty Column in SQL Server   SQL Training Online

http://www.sqltrainingonline.com SQL Null or Empty - How to Check for Null or Empty Column in SQL Server - SQL Training Online You can download the sample table script at http://www.sqltrainingonline.com/how-to-filter-for-sql-null-or-empty-string/. In this video, I show you how to filter for a SQL null or empty string. It can be difficult to filter a null because you can't simply compare with an equal sign. You have to use a special IS NULL clause to make the filter work. I also show you how to combine both the SQL Null and Empty String together in a special trick with the isnull SQL Server function. I use SQL Server 2012 to demonstrate the technique.

IS NULL Operator in SQL Query with Example
 
02:24
SQL IS NULL Operator: A column value is NULL if it does not exist. The IS NULL operator is used to display all the rows for columns that do not have a value. For Example: If you want to find the emp names who do not get any commision, the query would be as given below: select * from emp where COMM IS NULL; In the opposite way, NOT NULL also works here: select * from emp where COMM IS NOT NULL; Thanks for watching..:)

8. Use LOG ERRORS to suppress SQL errors at the row level.
 
06:23
The impact of a non-query DML statement is usually "all or nothing". If my update statement identifies 100 rows to change, then either all 100 rows are changed or none are. And none might be the outcome if, say, an error occurs on just one of the rows (value too large to fit in column, NULL value for non-NULL column, etc.). But if you have a situation in which you would really like to "preserve" as many of those row-level changes as possible, you can add the LOG ERRORS clause to your DML statement. Then, if any row changes raise an error, that information is written to your error log table, and processing continues. IMPORTANT: if you use LOG ERRORS, you must must must check that error log table immediately after the DML statement completes. You should also enhance the default error log table.

MySQL 17 - ON DELETE and ON UPDATE
 
04:32
Now, what happens when you have successfully created a reference, and now you try deleting the parent? This is where the ON DELETE clause come in. This is essentially how we configure how strict a foreign key is. There are 3 options you can give for an ON DELETE: RESTRICT / NO ACTION Yes - In MySQL they are the same, but not all DBMS. CASCADE Yes SET NULL Yes Now the default is RESTRICT. This means that when you try to delete a parent row, MySQL is going to throw an error and not let you. Cascade means that if you delete the parent row, any rows that reference that parent will also be deleted. This is pretty dangerous and not often recommended. SET NULL will set the foreign key to be NULL. Now obviously, this is going to require that the foreign key is not labelled NOT NULL. In addition to the ON DELETE clause, there is the ON UPDATE clause. This one is a little less common because it configures what happens when a parent value changes. Obviously, when you are referencing a primary key, the ON UPDATE clause is nearly useless. That's because the primary key value is never supposed to change. If, on the other hand, we have a foreign key referencing a UNIQUE column that is not a primary key, it may change occasionally. So the only times you have to worry about the ON UPDATE clause is with foreign keys referencing UNIQUE columns that are not a primary key, and when you have natural keys that break the rules and actually do change at some point in time. The ON UPDATE clause has the same options as the ON DELETE clause and they all work the same way. Now, the last thing you need to know about foreign keys is that they must match the data type of the column you are referencing. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

SQL with Oracle 10g XE - Using ALTER TABLE to Modify Table Columns
 
05:23
In this video I use the ALTER TABLE command to modify an existing field column. The command will allow you to change the data types, whether the field can be null, or even the primary key. When using the ALTER TABLE command you would use the keyword MODIFY to make changes to an existing column. Be careful when changing a data type of the null field as existing data may cause an error if not in compliance with the new change. The code I used to alter the Books table is : ALTER TABLE BOOKS MODIFY ISBN_10 VARCHAR(13); This video is part of a series of videos with the purpose of learning the SQL language.

A NULL value in a table is a value in a field that appears to be blank. A field with a NULL value is a field with no value. NULL value is different than a zero value or a field that contains spaces By default, a column can hold NULL values. The NOT NULL constraint enforces a column to NOT accept NULL values. This enforces a field to always contain a value, which means that you cannot insert a new record, or update a record without adding a value to this field

How to filter Rows with Null Values in Select Statement - SQL Server / TSQL Tutorial Part 110
 
09:08
SQL Server / T-SQL Tutorial Scenario: How to filter Rows with Null Values in Select Statement in SQL Server Let's say that you are working as SQL Server developer. You need to write two queries 1) Return all the records from dbo.Customer table where Address column has Null values 2) Return only the records from dbo.Customer table where Address column has the values other than Null. Link to scripts used in SQL Server / TSQL Tutorial Video http://www.techbrothersit.com/2016/06/how-to-filter-rows-with-null-values-in.html Check out our website for Different SQL Server, MSBI tutorials and interview questions such as SQL Server Reporting Services(SSRS) Tutorial SQL Server Integration Services(SSIS) Tutorial SQL Server DBA Tutorial SQL Server / TSQL Tutorial ( Beginner to Advance) http://www.techbrothersit.com/

Oracle SQL Tutorial 18 - How to Create Foreign Keys
 
07:09
In this video we are going to be creating foreign keys. I highly recommend watching the previous video before you watch this one. Essentially, we are creating a very simple database for a system where we can create projects and add people to those projects. We started with the users table: --Delete the table if needed: --DROP TABLE users; CREATE TABLE users( user_id NUMBER, username VARCHAR2(50 CHAR) UNIQUE, CONSTRAINT users_pk PRIMARY KEY (user_id) ); Now we are going to create a table for projects with a column that is a foreign key to the username. We're going to want to make this match data types: CREATE TABLE projects( project_id NUMBER, project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) ) Next, we need to add the column attributes we decided on last video: CREATE TABLE projects( project_id NUMBER, project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL ) NOT NULL because we want every project to have a creator, but we are not labeling UNIQUE because that means we could only have a specific username once in the table. We want to allow a user to create multiple projects. We also need to add a primary key: CREATE TABLE projects( project_id NUMBER, project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL, CONSTRAINT projects_pk PRIMARY KEY (username) ) Now, the question that remains is, how can I tell Oracle that I want the username to reference the username column of the other table? We have to make a foreign key constraint. As you've learned from the previous videos, there are about three ways to create constraints. You can do it inline at the column level, unnamed. You can do it at the column level, named, and you can do it at the Table level, named. Usually the table-level is preferred, but I will quickly remind you how to do all three again. CREATE TABLE projects( project_id NUMBER, project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL REFERENCES users (username), CONSTRAINT projects_pk PRIMARY KEY (project_id) ) This works, but if we want to name it, we should do this: CREATE TABLE projects( project_id NUMBER, project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL CONSTRAINT projects_users_fk REFERENCES users (username), CONSTRAINT projects_pk PRIMARY KEY (project_id) ) This works, but the preferred method is to do it at the table level: 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) ) Great! So you've learned how to create a foreign key, now we can see it inside of Oracle SQL Developer. One important thing when it comes to foreign keys is what happens when have data in your database and you try to delete the parent row that a row in the child table references? In the next video we are going to configure that using ON DELETE.

SQL with Oracle 10g XE - Using INSERT to Add Data to a Table
 
06:20
In this video I use the INSERT command to add an entire record into a table. When using the command you must also use the keyword VALUES. If you want to enter a null value (one that has no value) for a field you can use the keyword NULL. Be sure to put single quotes around data types that are not numbers. Values need to be entered in the order the fields appear in the table. The commands I used are: INSERT INTO BOOKS VALUES (1,'140231862','9780140231861','The Winter King: A Novel of Arthur','Fiction','14.99','P',1996,1,2) INSERT INTO BOOKS VALUES ('2','140232478','9780140232479','Enemy of God: A Novel of Arthor','Fiction',14.99,'P','1997',1,2); INSERT INTO BOOKS VALUES ('3','140232877','9780140232875','Excalibur: A Novel of Arthor','Fiction',14.99,'P','1998',1,2); INSERT INTO BOOKS VALUES ('4','6513840','9780006513841','Harlequin: Grail Quest','Fiction',19.99,'P','2001',1,1); INSERT INTO BOOKS VALUES ('5','6513859','9780006513858','Vagabond: Grail Quest','Fiction',19.99,'P','2003',1,1); INSERT INTO BOOKS VALUES ('6','7149891','9780007149896','Heretic: Grail Quest','Fiction',19.99,'P','2004',1,1); INSERT INTO BOOKS VALUES ('7','553103547','9780553103540','A Game of Thrones','Fiction',13.99,'H','1996',2,4); INSERT INTO BOOKS VALUES ('8','553801473','9780553801477','A Dance with Dragons','Fiction',13.99,'H','2010',2,5); INSERT INTO BOOKS VALUES ('9','055357342X','9780553573428','A Storm of Swords','Fiction',4.99,'P','2003',2,4); INSERT INTO BOOKS VALUES ('10','1596590424','9781596590427','50 Success Classics','Audio',17.99,NULL,NULL,3,3) INSERT INTO AUTHOR VALUES (1,'Cornwell','Bernard'); INSERT INTO AUTHOR VALUES (2,'Martin','George'); INSERT INTO AUTHOR VALUES (3,'Butler','Tom'); INSERT INTO PUBLISHER VALUES (1,'HarperCollins Publishers Canada, Limited'); INSERT INTO PUBLISHER VALUES (2,'Penguin Books Canada, Limited'); INSERT INTO PUBLISHER VALUES (3,'Gildan Media Corp'); INSERT INTO PUBLISHER VALUES (4,'Bantam Dell Pub Group'); INSERT INTO PUBLISHER VALUES (5,'Spectra'); This video is part of a series of videos with the purpose of learning the SQL language.

NULL Value in sql | Part 10 | SQL tutorial for beginners | Tech Talk Tricks
 
04:52
Welcome to our Tech Talk Tricks channel.The SQL NULL is the term used to represent a missing value. A NULL value in a table is a value in a field that appears to be blank. #TechTalkTricks #RanaSingh A field with a NULL value is a field with no value. It is very important to understand that a NULL value is different than a zero value or a field that contains spaces. Syntax The basic syntax of NULL while creating a table. SQL: CREATE TABLE CUSTOMERS( ID INT NOT NULL, NAME VARCHAR (20) NOT NULL, AGE INT NOT NULL, ADDRESS CHAR (25), SALARY DECIMAL (18, 2), PRIMARY KEY (ID) ); Here, NOT NULL signifies that column should always accept an explicit value of the given data type. There are two columns where we did not use NOT NULL, which means these columns could be NULL. A field with a NULL value is the one that has been left blank during the record creation. null value definition sql is null or empty sql is not null or empty null value statistics importance of null values in relational database sql if null sql isnull function sql if not null ************************************************** Follow Tech Talk Trick on Facebook https://www.facebook.com/techtalktricks ************************************************** Follow tech talk trick on Twitter https://twitter.com/tecktalktrick ************************************************** Follow Tech Talk Tricks on Instagram https://www.instagram.com/techtalktricks ************************************************** Subscribe tech talk tricks on YouTube https://www.youtube.com/techtalktricks ***************************************************

Difference between NVL,NVL2, NULLIF and COALESCE NVL function will check whether the first input parameter is null, if first input parameter is null then the function returns the second parameter value as output. NVL2 function will check the first parameter, and return second parameter if the first parameter is not null, otherwise returns third parameter. NULLIF will compare the input parameters ( first and second parameter ), and returns NULL of both are same, otherwise returns the first parameter value. COALESCE, returns the first not null expression in the given input parameters. -------------------------------------------------------------------------------------------------------- List of all the SQL and PLSQL interview questions https://easy-learning-tech.blogspot.com/p/oracle-sql-plsql-interview-questions.html
