Oracle EMPTY_BLOB Function
 
01:58
https://www.databasestar.com/oracle-lob-functions/ The Oracle EMPTY_BLOB function is used to initialise a LOB column to an empty value. 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. For more information about the Oracle EMPTY_BLOB function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-lob-functions/

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.

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.

SQL Server 30 - How to INSERT Data
 
05:48
Now that we have our tables created, we need to learn how to actually put data into our tables. That is where the INSERT command comes in. The basic syntax looks like: INSERT INTO TableName VALUES(data…); Data is where we put a value for each column. Strings are single quoted, numbers are left blank with no quotes. Just like when we create tables we try to create the parent tables first, we do the same with inserting data. We always want to insert the parent rows first. So let's add a species to our table. As a reminder, this is what our CREATE TABLE looks like: CREATE TABLE Species( ID INT PRIMARY KEY IDENTITY, Species VARCHAR(50) NOT NULL UNIQUE, FriendlyName VARCHAR(50) NOT NULL ); Now to insert data: INSERT INTO Species VALUES('Pentalagus P. furnessi', 'Bunny'); Now you can see that there may a violation of everything being atomic because we are actually storing the genus and species of this animal in one column. But…YOLO. Now we can view this data by finding the table in the object explorer, right clicking, and selecting Edit Top 200 Rows. Notice that the IDENTITY column is automatically filled. Now, this is a great time to show you some stuff regarding foreign keys. The first thing I want to show you is how they protect our data integrity. Let's insert some data in the Animals table and try to reference an invalid species. Once again, here is what our table creation looks like: CREATE TABLE Animals( ID INT PRIMARY KEY IDENTITY, Name VARCHAR(50) NOT NULL, Species INT NOT NULL REFERENCES Species(ID), ContactEmail VARCHAR(50) NOT NULL UNIQUE ); INSERT INTO Animals VALUES('Sally', 2, '[email protected]'); SQL Server does not let us insert this data. The second thing I wanted to show you is that the name of the constraint that is in violation is being shown here. That is why naming your constraints can come in handy so when this happens you can find it much easier. Last thing is that if you want to INSERT multiple rows, throw a comma after the VALUES, and put another parenthesis with more data: INSERT INTO Animals VALUES('Sally', 1', '[email protected]'), ('Franklin', 1, '[email protected]') ; Maybe someday we will get around to adding a row to our species table for turtles, but for now we are going to make Franklin a bunny. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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 Server 26 - PRIMARY KEY, NOT NULL, UNIQUE
 
03:36
In the last video we created our first table, but I want to give SQL Server some extra information so the database knows more about each of the columns. The first thing is to establish the primary key. To do this all we do is add PRIMARY KEY after the column we want to be the primary key. Simple enough. When we add a constraint right after the column like this, it is often called a column attribute. CREATE TABLE Animals( ID INT PRIMARY KEY, Name VARCHAR(50), Species VARCHAR(50) ); Additionally, if you are using an ID column, it is best to have it labeled as the IDENTITY column. That way, SQL Server will automatically increment the number. CREATE TABLE Animals( ID INT PRIMARY KEY IDENTITY, Name VARCHAR(50), Species VARCHAR(50) ); The other attributes we've discussed in this series are NOT NULL and UNIQUE. We can make the name NOT NULL and the species NOT NULL. We don't have a good column for UNIQUE, so let's add one: CREATE TABLE Animals( ID INT PRIMARY KEY IDENTITY, Name VARCHAR(50) NOT NULL, Species VARCHAR(50) NOT NULL, ContactEmail VARCHAR(50) NOT NULL UNIUQE ); You can see that it is very easy to add multiple column attributes to a column. Just separate them by spaces. The order does not matter. Also, when you say primary key the column is automatically NOT NULL and UNIQUE. There are other attributes you can use including DEFAULT, FOREIGN KEY, and SPARSE. DEFAULT will give a value for a column if you do not put anything in yourself. Foreign keys are used to reference other columns. SPARSE is an attribute we haven't discussed. You can use SPARSE if most of the rows are going to have a NULL for a column and it saves storage space, but we will worry about that in another 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!)

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!)

Oracle SQL PLSQL 12C Tutorial 7 - How to Insert Record or Data in Table
 
04:23
This Video Tutorial Will Describe how to insert values or data into the table in oracle 12C version. This command will also work on other versions of database like Oracle 11g Database, Oracle 10g Database, Oracle 9i Database, Oracle 8i Database, Oracle 8 Database and so on. Whenever you create a new table in oracle, you need to insert some data into that table otherwise that table is not usable. Example to select data, to update data and delete data, you first need to insert some data. Full Syntax will be given in this video tutorial about how to insert records in oracle database table. Along with the live example to insert records. All the keywords, format, mandatory clauses etc are described in this video. 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.
Oracle SQL Tutorial 13 - How to Add Column Constraints (Attributes)
 
05:55
So far, we have this table declaration: CREATE TABLE users( user_id NUMBER, username VARCHAR(50 CHAR) first_name VARCHAR2(50 CHAR), last_name VARCHAR2(50 CHAR) ) We can run this command see that it works. As we are learning though, we are going to want to be able to recreate our table with different settings and such, but if you try to run this command, it will complain that the table already exists. So we first need to delete this table before we start editing settings. When we get more experienced, we will learn about ways to edit the structure of a table that already exists. To fix this, we can get rid of the table using the DROP TABLE command: DROP TABLE users You can run this every time if you need to practice by adding a semicolon after it. This is how you can tell Oracle that you are putting in another command after it. This is known as a delimiter. When you run the script, it is going to run both commands. Now we can go through and reconsider our table structure. This is fine for starting out because we don't have any important data in our database, but once your database is in production you are not going to want to just drop tables. In the last video we discussed different constraints that you can apply to columns in a database table, but how do you actually apply these when you are creating a table? The first way you define constraints is to put them right after the column in your CREATE TABLE statement. CREATE TABLE users( username VARCHAR2(50 CHAR) NOT NULL ) When we define constraints this way, we usually say we are adding column attributes. If you have two constraints you want to add, you just put one after the other with spaces in between. There is no particular order that is required. CREATE TABLE users( username VARCHAR2(50 CHAR) NOT NULL UNIQUE ) In this situation we have already given the column the NOT NULL and UNIQUE attributes, so we should consider making this a primary key: CREATE TABLE users( username VARCHAR2(50 CHAR) PRIMARY KEY ) As you can see, adding column attributes is super easy. We can add a default like this: CREATE TABLE users( username VARCHAR2(50 CHAR) PRIMARY KEY, account_balance NUMBER DEFAULT 0 ) Note that now we need the comma after the first row. There are a few constraints we did not talk go through an example, specifically foreign keys and check constraints. We will be adding these constraints to our database in future videos. In the mean time, I have a thought for you… Many people prefer to name their column constraints. That way, we can refer to certain constraints by name. For example, we might have a primary key constraint that could be named users_pk. The way we are creating these constraints does not allow for this feature, so in the next video we are going to be discussing different ways to create constraints. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

Session7 INSERT Statement
 
24:08
Session 7: Populating(INSERT) data into database table in Oracle. 1. Insert data into all columns(complete record) in a table. 2. Insert data into a table in same/random order of column. 3. Insert data into selective columns of a table. 4. Inserting NULL value into table. 5. Prompt the column to insert values in runtime using ‘&' and ‘&&'. 6. Insert data using select statement. 7. Create table as select.(create table with/without data). 8. Insert huge amount of dummy data using a PL/SQL block. — Create a table. CREATE TABLE emp (EmpID NUMBER(4) PRIMARY KEY, EName VARCHAR2(20) NOT NULL, Job VARCHAR2(20), DeptNo NUMBER(3), Sal NUMBER(7,2)); Insert data into all columns(complete record) in a table. same order of column: INSERT INTO emp VALUES(111, 'SCOTT', 'MANAGER', 10, 50000); INSERT INTO emp(EmpID, EName, Job, DeptNo, Sal) VALUES(112, 'JONES', 'DESIGNER', 20, 40000); Random order of column values: INSERT INTO emp VALUES(113, 45000, 10, 'SMITH', 'MANAGER'); — show error, why ?? INSERT INTO emp(EmpID, Sal , DeptNo, EName, Job) VALUES(113, 45000, 10, 'SMITH', 'MANAGER'); Insert data into selective columns of a table. INSERT INTO emp VALUES(122, 10, 'SMITH'); — show error INSERT INTO emp(EmpID, DeptNo, EName) VALUES(222, 10, 'SMITH'); Inserting NULL value into table. INSERT INTO emp VALUES(214, 'JONES', NULL, NULL, 40000); INSERT INTO emp(EmpID, EName, Sal) VALUES(215, 'ADEMS', 40000); Prompt the column to insert values in runtime using ‘&' and ‘&&'. INSERT INTO emp VALUES(&empid, '&ename', '&job', &deptno, &sal); INSERT INTO emp VALUES(&empid, &ename, &job, &deptno, &sal); INSERT INTO emp(EmpID, EName, Job, DeptNo, Sal) VALUES (&empid, '&ename', '&job', &deptno, &sal); INSERT INTO emp(EmpID, DeptNo, EName) VALUES (&empid, &deptno, '&ename'); INSERT INTO emp(EmpID, DeptNo, EName, Sal) VALUES (&empid, &&deptno, '&ename', &&sal); Insert data using select statement. INSERT INTO emp (SELECT 222, 'SATISH', 'MANAGER', 30, 60000 FROM DUAL); INSERT INTO emp VALUES(SELECT 223, 'RAHUL', 'SALESMAN', 30, 30000 FROM DUAL); — show error. Create table as select.(create table with/without data). CREATE TABLE emp_copy AS SELECT * FROM emp; — create table with same table structure, with data. SELECT * FROM tab; SELECT * FROM emp_copy; CREATE TABLE emp_copy2 AS SELECT * FROM emp where 1 != 1; — create table with same table structure, without data. SELECT * FROM tab; SELECT * FROM emp_copy2; Insert huge amount of dummy data using a PL/SQL block. BEGIN FOR i IN 1..100 LOOP INSERT INTO emp VALUES(i, 'Ename_'||i, 'Job_'||i, (MOD(i,5)+1)*10, (MOD(i,5)+1)*10000); END LOOP; END; / SELECT * FROM emp;

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 ***************************************************

SQL script to insert into many to many table

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#'

Part 2   SQL query to get organization hierarchy
 
10:14
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-2-sql-query-to-get-organization.html To get the best out of this video, the following concepts need to be understood first. These are already discussed in SQL Server Tutorial. 1. Self-Join - http://www.youtube.com/watch?v=qnYSN_7qwgg 2. CTE - http://www.youtube.com/watch?v=ZXB5b-7HJHk 3. Recursive CTE - http://www.youtube.com/watch?v=GGoV0wTMCg0 Here is the problem definition: 1. Employees table contains the following columns a) EmployeeId, b) EmployeeName c) ManagerId 2. If an EmployeeId is passed, the query should list down the entire organization hierarchy i.e who is the manager of the EmployeeId passed and who is managers manager and so on till full hierarchy is listed. For example, Scenario 1: If we pass David's EmployeeId to the query, then it should display the organization hierarchy starting from David. Scenario 2: If we pass Lara's EmployeeId to the query, then it should display the organization hierarchy starting from Lara. We will be Employees table for this demo. SQL to create and populate Employees table with test data Create table Employees ( EmployeeID int primary key identity, EmployeeName nvarchar(50), ManagerID int foreign key references Employees(EmployeeID) ) GO Insert into Employees values ('John', NULL) Insert into Employees values ('Mark', NULL) Insert into Employees values ('Steve', NULL) Insert into Employees values ('Tom', NULL) Insert into Employees values ('Lara', NULL) Insert into Employees values ('Simon', NULL) Insert into Employees values ('David', NULL) Insert into Employees values ('Ben', NULL) Insert into Employees values ('Stacy', NULL) Insert into Employees values ('Sam', NULL) GO Update Employees Set ManagerID = 8 Where EmployeeName IN ('Mark', 'Steve', 'Lara') Update Employees Set ManagerID = 2 Where EmployeeName IN ('Stacy', 'Simon') Update Employees Set ManagerID = 3 Where EmployeeName IN ('Tom') Update Employees Set ManagerID = 5 Where EmployeeName IN ('John', 'Sam') Update Employees Set ManagerID = 4 Where EmployeeName IN ('David') GO Here is the SQL that does the job Declare @ID int ; Set @ID = 7; WITH EmployeeCTE AS ( Select EmployeeId, EmployeeName, ManagerID From Employees Where EmployeeId = @ID UNION ALL Select Employees.EmployeeId , Employees.EmployeeName, Employees.ManagerID From Employees JOIN EmployeeCTE ON Employees.EmployeeId = EmployeeCTE.ManagerID ) Select E1.EmployeeName, ISNULL(E2.EmployeeName, 'No Boss') as ManagerName From EmployeeCTE E1 LEFT Join EmployeeCTE E2 ON E1.ManagerID = E2.EmployeeId
