Row Number function in SQL Server
 
07:24
sql server row_number example sql server row number by partition sql server row_number over partition by order by In this video we will discuss Row_Number function in SQL Server. This is continuation to Part 108. Please watch Part 108 from SQL Server tutorial before proceeding. Row_Number function Introduced in SQL Server 2005 Returns the sequential number of a row starting at 1 ORDER BY clause is required PARTITION BY clause is optional When the data is partitioned, row number is reset to 1 when the partition changes Syntax : ROW_NUMBER() OVER (ORDER BY Col1, Col2) Row_Number function without PARTITION BY : In this example, data is not partitioned, so ROW_NUMBER will provide a consecutive numbering for all the rows in the table based on the order of rows imposed by the ORDER BY clause. SELECT Name, Gender, Salary, ROW_NUMBER() OVER (ORDER BY Gender) AS RowNumber FROM Employees Please note : If ORDER BY clause is not specified you will get the following error The function 'ROW_NUMBER' must have an OVER clause with ORDER BY Row_Number function with PARTITION BY : In this example, data is partitioned by Gender, so ROW_NUMBER will provide a consecutive numbering only for the rows with in a parttion. When the partition changes the row number is reset to 1. SELECT Name, Gender, Salary, ROW_NUMBER() OVER (PARTITION BY Gender ORDER BY Gender) AS RowNumber FROM Employees Use case for Row_Number function : Deleting all duplicate rows except one from a sql server table.

PL/SQL tutorial | Cursor in Oracle Database 11g Complete guide
 
13:50
Learn in depth about cursor in oracle database 11g, and why to use cursor.Writing Implicit cursor and explicit cursor following using 'for loop' inside cursor to fetch multiple records from oracle database. Cursor in Oracle Cursor in PL/SQL Oracle Cursor PL/SQL Cursor What is cursor in PL/SQL How to use cursor in PL/SQL Implicit cursor in PL/SQL Explicit cursor in PL/SQL A cursor is a pointer to this context area. PL/SQL controls the context area through a cursor. A cursor holds the rows (one or more) returned by a SQL statement. The set of rows the cursor holds is referred to as the active set. Implicit Cursors Implicit cursors are automatically created by Oracle whenever an SQL statement is executed, when there is no explicit cursor for the statement. Programmers cannot control the implicit cursors and the information in it. %FOUND Returns TRUE if an INSERT, UPDATE, or DELETE statement affected one or more rows or a SELECT INTO statement returned one or more rows. Otherwise, it returns FALSE. %NOTFOUND The logical opposite of %FOUND. It returns TRUE if an INSERT, UPDATE, or DELETE statement affected no rows, or a SELECT INTO statement returned no rows. Otherwise, it returns FALSE. %ISOPEN Always returns FALSE for implicit cursors, because Oracle closes the SQL cursor automatically after executing its associated SQL statement. %ROWCOUNT Returns the number of rows affected by an INSERT, UPDATE, or DELETE statement, or returned by a SELECT INTO statement. Explicit Cursors Explicit cursors are programmer-defined cursors for gaining more control over the context area. An explicit cursor should be defined in the declaration section of the PL/SQL Block. It is created on a SELECT Statement which returns more than one row Linkedin: https://www.linkedin.com/in/aditya-kumar-roy-b3673368/ Facebook: https://www.facebook.com/SpecializeAutomation/

How to get random rows from SQL Server Table - TSQL Tutorial Part 117
 
09:50
SQL Server / T-SQL Tutorial Scenario: How to get random rows from SQL Server Table Scenario: You are working as SQL Server developer. You are asked to provide sample random data from dbo.Customer table. You might asked to provide random 100 rows or some percent of total data from table. What query you will use to provide required output? Solution: In previous post, we learnt how to get top n rows from table. We can either provide row count or percent of records we want to get from a table by using TOP in our select query. We can use the same Top clause but as we are asked to provide the random records, we need to sort them randomly first. We can use newid() function in order by clause to sort them randomly.

Over clause in SQL Server
 
09:13
over partition by in sql server 2008 sql server over clause partition partition by clause in sql server 2008 over partition by clause in sql In this video we will discuss the power and use of Over clause in SQL Server. The OVER clause combined with PARTITION BY is used to break up data into partitions. Syntax : function (...) OVER (PARTITION BY col1, Col2, ...) The specified function operates for each partition. For example : COUNT(Gender) OVER (PARTITION BY Gender) will partition the data by GENDER i.e there will 2 partitions (Male and Female) and then the COUNT() function is applied over each partition. Any of the following functions can be used. Please note this is not the complete list. COUNT(), AVG(), SUM(), MIN(), MAX(), ROW_NUMBER(), RANK(), DENSE_RANK() etc. Example : SQl Script to create Employees table Create Table Employees ( Id int primary key, Name nvarchar(50), Gender nvarchar(10), Salary int ) Go Insert Into Employees Values (1, 'Mark', 'Male', 5000) Insert Into Employees Values (2, 'John', 'Male', 4500) Insert Into Employees Values (3, 'Pam', 'Female', 5500) Insert Into Employees Values (4, 'Sara', 'Female', 4000) Insert Into Employees Values (5, 'Todd', 'Male', 3500) Insert Into Employees Values (6, 'Mary', 'Female', 5000) Insert Into Employees Values (7, 'Ben', 'Male', 6500) Insert Into Employees Values (8, 'Jodi', 'Female', 7000) Insert Into Employees Values (9, 'Tom', 'Male', 5500) Insert Into Employees Values (10, 'Ron', 'Male', 5000) Go Write a query to retrieve total count of employees by Gender. Also in the result we want Average, Minimum and Maximum salary by Gender. This can be very easily achieved using a simple GROUP BY query as show below. SELECT Gender, COUNT(*) AS GenderTotal, AVG(Salary) AS AvgSal, MIN(Salary) AS MinSal, MAX(Salary) AS MaxSal FROM Employees GROUP BY Gender What if we want non-aggregated values (like employee Name and Salary) in result set along with aggregated values You cannot include non-aggregated columns in the GROUP BY query. SELECT Name, Salary, Gender, COUNT(*) AS GenderTotal, AVG(Salary) AS AvgSal, MIN(Salary) AS MinSal, MAX(Salary) AS MaxSal FROM Employees GROUP BY Gender The above query will result in the following error : Column 'Employees.Name' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause One way to achieve this is by including the aggregations in a subquery and then JOINING it with the main query as shown in the example below. Look at the amount of T-SQL code we have to write. SELECT Name, Salary, Employees.Gender, Genders.GenderTotals, Genders.AvgSal, Genders.MinSal, Genders.MaxSal FROM Employees INNER JOIN (SELECT Gender, COUNT(*) AS GenderTotals, AVG(Salary) AS AvgSal, MIN(Salary) AS MinSal, MAX(Salary) AS MaxSal FROM Employees GROUP BY Gender) AS Genders ON Genders.Gender = Employees.Gender Better way of doing this is by using the OVER clause combined with PARTITION BY SELECT Name, Salary, Gender, COUNT(Gender) OVER(PARTITION BY Gender) AS GenderTotals, AVG(Salary) OVER(PARTITION BY Gender) AS AvgSal, MIN(Salary) OVER(PARTITION BY Gender) AS MinSal, MAX(Salary) OVER(PARTITION BY Gender) AS MaxSal FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/over-clause-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/over-clause-in-sql-server_29.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

PLSQL Básico - Cursores Implicitos (vs cursores explìcitos) - Excepciones
 
21:50
Un cursor implícito es ejecutado cuando una sentencia DML es lanzada. En el caso de las sentencias UPDATE, DELETE, INSERT no es necesario agregar más código para ser usadas aunque se puede obtener informacion del proceso que ejecutaron tal como ver si encontró el set a procesar con SQL%FOUND o SQL%NOTFOUND y cuantas lineas fueron procesadas con SQL%ROWCOUNT. En el caso de la sentencia SELECT es donde se dan más diferencias ya que un cursor implícito está diseñado para regresar el resultado de una sola fila con una o más columnas, en el caso de que haya más de un resultado o ninguno, enviará un mensaje de error, cuando el manejo de los errores lo hacemos en la parte de EXCEPTION estamos transladando escenarios previstos a una parte de excepciones que tiene otro propósito. Se recomienda siempre usar cursores explícitos ya que nos da control para el manejo de los distintos escenarios por lo tanto también se muestran las diferencias entre usar cursores implícitos y explicitos.

Import Multiple Text or CSV files to SQL Server Table by using Script Task in SSIS Package-P172
 
20:11
SSIS Video Scenario: How to Import Multiple Text or CSV files to SQL Server Table by using Script Task in SSIS Package You are working as ETL Developer / SSIS Developer. You get single or multiple text/csv files in Source Folder on daily basis. You want to create an SSIS Package that should be able to load all the files to single Table and archive after loading to table. You want to built this package with configuration so by only provide different configuration values, it should be able to handle below scenarios 1) If your file provider decided to provide .txt file, it should be able to take them and load them 2) if your file provide decided to provide .csv files , by changing configuration value , package should be able to load the files 3) Table Name can change any time, so you should be able to provide table name by using configuration 4) Source Folder Path and Archive Folder Path can change, so you should be able to handle through configuration 5) File delimiter can also change, let's say you are getting files with comma(,). The file provider can make decision moving forward, he will be provide files with pipe( | ) .

11 MySQL Tutorial for Beginners: The LIMIT Clause
 
06:36
The LIMIT clause limits the number of rows in the result set. In its simplest form, you code the LIMIT clause with a single numeric argument. If you code a single argument, it specifies the maximum row count, beginning with the first row. If you code two arguments in a LIMIT clause, the first one represents the starting point for the result set, also called the "offset". This "offset" starts to count from a value of zero. This means that zero refers to the first row in the result set, one to the second, two to the third and so on. SELECT, FROM, WHERE, ORDER BY, and LIMIT are the five main clauses of the SELECT statement but only the SELECT clause is required. When you code the SELECT clause, you should include only the columns you really need (for example, you shouldn't code an asterisk to retrieve all the columns unless you need all the columns). That's because the amount of data that's retrieved can affect system performance. That goes for retrieving rows too. The fewer rows you retrieve, the more efficient the statement will be. Because of that, you typically include a WHERE clause on your SELECT statements with a search condition that filters the rows in the base table so only the rows you need are retrieved EXERCISES for your SELF-TRAINING: http://golearnfast.com/Quizzes.php?_SelectSmallerGroup_288=0&Lessons_ID=288 SCRIPT FOR THE EXAMPLES: http://www.golearnfast.com/files/lessons_material/lesson_277_1440544998.sql SUBSCRIBE! https://www.youtube.com/channel/UCMEaGDoHU7c9tWyafZ9vC6Q?sub_confirmation=1 FACEBOOK https://www.facebook.com/golearnfast GOOGLE+ https://plus.google.com/u/0/b/101326338689489366802/
