IIF function in SQL Server
 
04:00
iif function in sql server 2012 iif function in sql server example sql server iif function example In this video we will discuss IIF function in SQL Server. IIF function Introduced in SQL Server 2012 Returns one of two the values, depending on whether the Boolean expression evaluates to true or false IIF is a shorthand way for writing a CASE expression Syntax : IIF ( boolean_expression, true_value, false_value ) Example : Returns Male as the boolean expression evaluates to TRUE DECLARE @Gender INT SET @Gender = 1 SELECT IIF( @Gender = 1, 'Male', 'Femlae') AS Gender Example : Using IIF() function with table data. We will use the following Employees table for this example. SQL Script to create Employees table Create table Employees ( Id int primary key identity, Name nvarchar(10), GenderId int ) Go Insert into Employees values ('Mark', 1) Insert into Employees values ('John', 1) Insert into Employees values ('Amy', 2) Insert into Employees values ('Ben', 1) Insert into Employees values ('Sara', 2) Insert into Employees values ('David', 1) Go Write a query to display Gender along with employee Name and GenderId. We can achieve this either by using CASE or IIF. Using CASE statement SELECT Name, GenderId, CASE WHEN GenderId = 1 THEN 'Male' ELSE 'Female' END AS Gender FROM Employees Using IIF function SELECT Name, GenderId, IIF(GenderId = 1, 'Male', 'Female') AS Gender FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/iif-function-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/iif-function-in-sql-server_14.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

Logical Functions in SQL SERVER 2012 || CHOOSE and IIF functions in SQL Server 2012
 
04:07
This video will provide you the details of each Logical Function in SQL Server 2012. *****************************************************************************  Logical Functions (Transact-SQL)  CHOOSE (Transact-SQL) Returns the item at the specified index from a list of values in SQL Server.  Syntax CHOOSE ( index, val_1, val_2 [, val_n ] )  Arguments index Is an integer expression that represents a 1-based index into the list of the items following it. If the provided index value has a numeric data type other than int, then the value is implicitly converted to an integer. If the index value exceeds the bounds of the array of values, then CHOOSE returns null. val_1 … val_n List of comma separated values of any data type.  Return Types Returns the data type with the highest precedence from the set of types passed to the function.  Remarks CHOOSE acts like an index into an array, where the array is composed of the arguments that follow the index argument. The index argument determines which of the following values will be returned. DECLARE @a int = 3 select CASE WHEN @a=1 THEN 'DEVELOPER' WHEN @a=2 THEN 'TESTER' WHEN @a=3 THEN 'SUPPORT' ELSE 'MANAGER' END AS RESULT *****************************************************************************  IIF (Transact-SQL) Returns one of two values, depending on whether the Boolean expression evaluates to true or false in SQL Server.  Syntax IIF ( boolean_expression, true_value, false_value )  Arguments boolean_expression A valid Boolean expression. If this argument is not a Boolean expression, then a syntax error is raised. true_value Value to return if boolean_expression evaluates to true. false_value Value to return if boolean_expression evaluates to false.  Return Types Returns the data type with the highest precedence from the types in true_value and false_value.  Remarks IIF is a shorthand way for writing a CASE expression. It evaluates the Boolean expression passed as the first argument, and then returns either of the other two arguments based on the result of the evaluation. That is, the true_value is returned if the Boolean expression is true, and the false_value is returned if the Boolean expression is false or unknown. true_value and false_value can be of any type. The same rules that apply to the CASE expression for Boolean expressions, null handling, and return types also apply to IIF The fact that IIF is translated into CASE also has an impact on other aspects of the behavior of this function. Since CASE expressions can be nested only up to the level of 10, IIF statements can also be nested only up to the maximum level of 10. Also, IIF is remoted to other servers as a semantically equivalent CASE expression, with all the behaviors of a remoted CASE expression. 

Oracle APEX - User Authorization Schemes
 
05:10
#orclapex #oracleapex #oracleapexbd An authorization scheme extends the security of your application's authentication scheme. You can specify an authorization scheme for an entire application, page, or specific control such as a region, item, or button. For example, you could use an authorization scheme to selectively determine which tabs, regions, or navigation bars a user sees. An authorization scheme either succeeds or fails. Common authorization scheme types include Exists, Not Exists SQL Queries, and PL/SQL Function Returning Boolean. If a component or control level authorization scheme succeeds, the user can view the component or control. If it fails, the user cannot view the component or control. If an application or page-level authorization scheme fails, then Oracle Application Express displays a previously defined message. When you define an authorization scheme, you give it a unique name. Once defined, you can attach it to any component or control in your application. To attach an authorization scheme to a component or control in your application, simply navigate to the appropriate attributes page and select an authorization scheme from the Authorization Scheme list. You can control access to a specific page or page component by selecting one of these authorization schemes on the page or component attributes pages. Once you create an Access Control, you can customize the page, tables and values to suit the specific needs of your application.

On the Fourier Spectrum of Symmetric Boolean Functions - Amir Shpilka
 
47:07
Amir Shpilka Technion; on leave at Microsoft Research New England March 14, 2011 It is well-known that any Boolean function f:{-1,+1}^n \to {-1,+1} can be written uniquely as a polynomial f(x) = \sum_{S subset [n]} f_s \prod_{i in S} x_i. The collection of coefficients (f_S's) this expression are referred to (with good reason) as the Fourier spectrum of f. The Fourier spectrum has played a central role in modern computer science by converting combinatorial and algorithmic questions about f into algebraic or analytic questions about the spectrum. In this talk I will focus on a basic feature of the Fourier spectrum, namely the minimal Fourier degree, or the size of the smallest non-empty set S such that f_S is non-zero. For every symmetric function *except the parity function* we show that the minimal Fourier degree is at most O(Gamma(n)) where Gamma(m) less than m^{0.525} is the largest gap between consecutive prime numbers in {1,...,m}. This improves the previous result of Kolountzakis et al. (Combinatorica '09) who showed that the minimal Fourier degree is at most k/log k. As an application we obtain a new analysis of the PAC learning algorithm for symmetric juntas, under the uniform distribution, of Mossel et al. (STOC '03). This is a joint work with Avishay Tal.

Hide Those Business Rules and Formulas! (HC-5)
 
12:18
Business rules and formulas are among the most important parts of our code, and they are top candidates for constant change. So don't expose (hard-code) them in your programs! No matter how simple, they should be hidden behind a procedure or function, usually a function, especially for formulas. That way, it is defined in one place and can be easily maintained. In this video, Steven shows examples of this process, and emphasizes that even with the most obvious rules, you can never assume it will stay correct. ================================================== Copyright © 2015 Oracle and/or its affiliates.

Types Of Triggers: We can code PL/SQL in a variety of triggers in a report to provide conditional or additional processing at run times. There are three Trigger types in Oracle Reports, such as: Report -Five Triggers Data Model -Parameter validation Layout -Format trigger Report Trigger: Report triggers enable you to execute PL/SQL functions at specific times during the execution and formatting of your report. The function must return a Boolean value (TRUE or FALSE). Using this triggers, You can do things such as -customize the formatting of your report -perform initialization tasks -and access the database. To create or modify a report trigger, you use the Report Triggers node in the Object Navigator. Types Of Report Trigger: Oracle Reports has five global report triggers. You cannot create new global report triggers, such as: Before Parameter Form trigger After Parameter Form trigger Before Report trigger Between Pages trigger After Report trigger Before Parameter Form trigger: -It is fire before opening the parameter form After Parameter Form trigger: -It is fire after closing the parameter form Before Report trigger: -It is fire before opening the report output Between Pages trigger: -It is fire for each and every page except first page.

However, to select the sequence, the CASE statement uses a selector rather than multiple Boolean expressions. A selector is an expression, whose value is used to select one of several alternatives.

There are three Trigger types in Oracle Reports, such as: Report -Five Triggers Data Model -Parameter validation Layout -Format trigger About Format Trigger: A format trigger is a user-written PL/SQL function that executes each time before the object containing the trigger is formatted. The function must return a Boolean value (TRUE or FALSE). The trigger can be used to dynamically change the formatting attributes of the object. You can access format triggers from the Object Navigator, the Property Inspector, or the PL/SQL Editor.

Part 21 Learn If , Case, While in Sql Server in Hindi tutorial for beginners
 
06:21
The IF…ELSE statement imposes conditions on the execution of a Transact-SQL (T-SQL) statement. The T-SQL statement that follows an IF keyword is executed if its condition is satisfied. In that case the Boolean expression returns a TRUE value. When the IF condition is not satisfied and the Boolean expression returns FALSE, the optional ELSE keyword introduces another Transact-SQL statement and condition which is executed. This IF…ELSE statement is very similar to that of C Programming. he SQL Server (Transact-SQL) CASE statement has the functionality of an IF-THEN-ELSE statement. You can use the CASE statement within a SQL statement. Syntax The syntax for the CASE statement in SQL Server (Transact-SQL) is: CASE expression WHEN value_1 THEN result_1 WHEN value_2 THEN result_2 ... WHEN value_n THEN result_n ELSE result END

What is LIKE Logical Operator in SQL Server - SQL Server  /TSQL Tutorial Part 123
 
16:27
SQL Server / T-SQL Tutorial Scenario: What is LIKE Logical Operator : LIKE logical operator is used when we want to return the row if operand matches a pattern. Like operator returns TRUE if the operand matches a pattern. Sometime we need to perform pattern matching instead of equal or not equal. Like is used when we want to return the row if specific character string matches a specified pattern. Pattern can be combination of regular characters and wildcard characters. To return the row back, regular characters must exactly match the characters specified in the character string.The wildcard characters can be matched with arbitrary parts of the character string.
