range vs rows in sql server difference between rows clause and range clause in sql server range clause vs rows clause in sql server sql server running total query running total example in sql server In this video we will discuss the difference between rows and range in SQL Server. This is continuation to Part 116. Please watch Part 116 from SQL Server tutorial before proceeding. Let us understand the difference with an example. We will use the following Employees table in this demo. SQL Script to create the Employees table Create Table Employees ( Id int primary key, Name nvarchar(50), Salary int ) Go Insert Into Employees Values (1, 'Mark', 1000) Insert Into Employees Values (2, 'John', 2000) Insert Into Employees Values (3, 'Pam', 3000) Insert Into Employees Values (4, 'Sara', 4000) Insert Into Employees Values (5, 'Todd', 5000) Go Calculate the running total of Salary and display it against every employee row The following query calculates the running total. We have not specified an explicit value for ROWS or RANGE clause. SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary) AS RunningTotal FROM Employees So the above query is using the default value which is RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW This means the above query can be re-written using an explicit value for ROWS or RANGE clause as shown below. SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS RunningTotal FROM Employees We can also achieve the same result, by replacing RANGE with ROWS SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS RunningTotal FROM Employees What is the difference between ROWS and RANGE To understand the difference we need some duplicate values for the Salary column in the Employees table. Execute the following UPDATE script to introduce duplicate values in the Salary column Update Employees set Salary = 1000 where Id = 2 Update Employees set Salary = 3000 where Id = 4 Go Now execute the following query. Notice that we get the running total as expected. SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS RunningTotal FROM Employees The following query uses RANGE instead of ROWS SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS RunningTotal FROM Employees Notice we don't get the running total as expected. So, the main difference between ROWS and RANGE is in the way duplicate rows are treated. ROWS treat duplicates as distinct values, where as RANGE treats them as a single entity. All together side by side. The following query shows how running total changes 1. When no value is specified for ROWS or RANGE clause 2. When RANGE clause is used explicitly with it's default value 3. When ROWS clause is used instead of RANGE clause SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary) AS [Default], SUM(Salary) OVER(ORDER BY Salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS [Range], SUM(Salary) OVER(ORDER BY Salary ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS [Rows] FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-rows-and-range.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-rows-and-range_8.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

http://www.sqltrainingonline.com SQL Date Comparison - How to filter Datetime in SQL Server - SQL Training Online In this video, I show you how to do a SQL Date Comparison in SQL Server when your Datetime has an actual time in it. I also include the latest trick that will make this easier if you are using SQL Server 2008 or SQL Server 2012. How do you compare a Datetime in SQL Server? A SQL Datetime stores both Date and Time. So when you are filtering using the SQL Where clause, you have to know if you Datetime is storing the time also. Let's take a look at the employee table in SQL Training Online Simple DB The column we are looking at is the hire date. I want to go after the person who was hired on February, 22 2005. So, I use the following SQL. select * from employee where hire_date='02/22/2005' Now, this works because we don't have any times stored in this column. But, if I change the record from 2005-02-22 00:00:00.000 to 2005-02-22 08:22:25.000 and rerun the query, you see that I don't get any results. That is because the value of 02/22/2005 is really 2005-02-22 00:00:00.000 and I just changed the hire_date to include a time other than 00:00:00.000. So, I have to tweak my query to use a greater than and less than sign. This works. But, to really understand what is going on, let me show you what SQL Server really sees. There are other ways, and in this StackOverflow article you can read more about these other ways. But, I want to point out a few. If you are working in SQL Server 2005 or earlier, the following is supposed to be the fastest performing way to do this. select datediff(dd,0, hire_date),* from employee where dateadd(dd,0, datediff(dd,0, hire_date)) = '2005-02-22' But, if you are working in SQL Server 2008 or SQL Server 2012, they have introduced an actual Date datatype that doesn't include the Time portion. Since this is the case, you can use the CAST function to remove the time from the Datetime. Here is the SQL to do that. select * from employee where CAST(hire_date AS Date) = '2005-02-22' And that's it. If you enjoy the video, please give it a like, comment, or subscribe to my channel.

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

A new series using APEX 18.1 is now available. https://youtu.be/vgrkiIpJEiQ This is one in a series of videos about creating an application using Oracle APEX 5. In this video we create two lists of values (LOVs) in the Shared Components section of our application. We use each LOV in place of a field in a form. We see how APEX will help us write the SQL for a LOV. The difference between a "display value"and a "return value"is discussed. Finally, we display the primary key field in a form, which APEX hides by default. See the primary key field in a form can be helpful during application development.

This video demonstrated how to change the logic of a given row calculation based on the value in another column. You may run in to a scenerion where you need to implement this when you have a requirement that the rows with one dimension value have logic "X" (for instance Mean) and the the rows with a different dimension value have logic "Y" (for instance a Median) assigned. This is accomplished with the Switch (Case) expression in the OBIEE formula builder.

ID column in Departments table is not the primary Key and DepartmentId column in Employees table is not the foreign key. But we can still join these tables using ID column from Departments table and DepartmentId column from Employees table, as both the columns involved in the join have same data type i.e int. Select Employees.Name as EmployeeName, Departments.Name as DepartmentName from Employees join Departments on Departments.ID = Employees.DepartmentId The obious next question is, if primary foreign key relation is not mandatory for 2 tables to be joined then what is the use of these keys? Primary key enforces uniqueness of values over one or more columns. Since ID is not a primary key in Departments table, 2 or more departments may end up having same ID value, which makes it impossible to distinguish between them based on the ID column value. Foreign key enforces referential integrity. Without foreign key constraint on DepartmentId column in Employees table, it is possible to insert a row into Employees table with a value for DepartmentId column that does not exist in Departments table. The following insert statement, successfully inserts a new Employee into Employees table whose DepartmentId is 100. But we don't have a department with ID = 100 in Departments table. This means this employee row is an orphan row, and the referential integrity is lost as result Insert into Employees values (8, 'Mary', 'Female', 80000, 100) If we have had a foreign key constraint on DepartmentId column in Employees table, the following insert statement would have failed with the following error. Msg 547, Level 16, State 0, Line 1 The INSERT statement conflicted with the FOREIGN KEY constraint. The conflict occurred in database "Sample", table "dbo.Departments", column 'ID'.

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.

In the previous tutorials, we've covered creating a database and populating one, now we need to learn how to read from the database. Reading from a database is where the power of using something like SQLite over a flat file starts to make sense. While we can query the entire table, we can instead just query a single column, or even based on specific row values. Let's see what I mean sample code and text tutorial: https://pythonprogramming.net/sqlite-part-3-reading-database-python/ Playlist: https://www.youtube.com/playlist?list=PLQVvvaa0QuDezJh0sC5CqXLKZTSKU1YNo https://pythonprogramming.net https://twitter.com/sentdex https://www.facebook.com/pythonprogramming.net/ https://plus.google.com/+sentdex

The script should be quite easy to read now as we use a while loop to read in the CSV file. We change the file delimiter to be the comma and then we have the line that we read in broken up into the schema elements we need. A report then is easy with colours and search ability.

http://www.sqltrainingonline.com SQL Into - How to Copy Table Data with Select Into Statement - SQL Training Online In this video, I show you how to copy data using the SQL INTO statement. Including a trick to copy only a table schema in SQL Server. How do you copy a whole table in SQL Server? You often see the SQL INTO statement when you are using INSERT, but there is a special INTO statement in SQL Server that is used with the SELECT statement that allows you to make a copy of a table for development, testing, or whatever purpose you can think of. So, to start, let's take a look at the SQL Training Online Simple DB employee table. You can see that we have 14 records Now, all we have to do to make a copy of the table is to simply add the SQL INTO clause: SELECT * INTO EMPLOYEE_TEST FROM EMPLOYEE If we run that, you see that we made a copy of the table with all of the data. Now, I want to go ahead and empty the employee_test table and show you how to use the INSERT INTO. If you already have a copy of the table, (I will show you a shortcut in a minute on how to create a copy without data.) then you can use the following insert into statement: INSERT INTO EMPLOYEE_TEST SELECT * FROM EMPLOYEE After running that statement, you see that I have inserted data from the Employee table into the employee_test table. This is sometimes referred to as INSERT INTO SELECT. But, there is one trick that I have used throughout the years that is pretty cool. Sometimes, you want the table schema, but you don't want the data. Now, I know that you can use Management Studio to script out the table for you, but there is an easier way that is more flexible as far as I am concerned. That is to use the SELECT INTO FROM, but put the following in the WHERE clause: SELECT * INTO EMPLOYEE_TEST FROM EMPLOYEE WHERE 1=2 The 1=2 makes is so not data will come over, but you get the new table with the right column types. Is that pretty cool? I have found many uses for this over the years. Let me know what you think bellow.

The Oracle DECOMPOSE function is used to transform a string into a Unicode string. It will split a character that has an accent, for example, into two characters. It’s the opposite of the COMPOSE function. The syntax of the DECOMPOSE function is: DECOMPOSE ( input_string [CANONICAL|COMPATIBILITY] ) The parameters of this function are: - input_string is the string that will be decomposed into separate character values in a string. It can be any character data type. - CANONICAL|COMPATIBILITY is an optional parameter and allows you to specify the mode of decomposition. CANONICAL is the default. CANONICAL means it can be re-composed with the COMPOSE function. COMPATIBILITY means that it can’t be re-composed, but it can be useful for katakana characters.
