SQL Script to create Employees table Create table Employees ( ID int, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values (1, 'Mark', 'Hastings', 'Male', 60000) Insert into Employees values (1, 'Mark', 'Hastings', 'Male', 60000) Insert into Employees values (1, 'Mark', 'Hastings', 'Male', 60000) Insert into Employees values (2, 'Mary', 'Lambeth', 'Female', 30000) Insert into Employees values (2, 'Mary', 'Lambeth', 'Female', 30000) Insert into Employees values (3, 'Ben', 'Hoskins', 'Male', 70000) Insert into Employees values (3, 'Ben', 'Hoskins', 'Male', 70000) Insert into Employees values (3, 'Ben', 'Hoskins', 'Male', 70000) The delete query should delete all duplicate rows except one. Here is the SQL query that does the job. PARTITION BY divides the query result set into partitions.

We have already discussed the intro of SQL character function in Video 10. You can find link of this video in description below. Ok let's go ahead. SQL Concat () function concatenates two separate character string into one character string. Let's see the syntax Concat (string_1 , String_2) Note here that SQL Concat function takes only two arguments at a time. This SQL Concat function will return string_1 concatenated with string_2. This also means that it will return a single string which is a combined string of parameter String_1 and String_2. Both the parameters of SQL Concat function String_1 and string_2 can be of any data-type. You can even specify the columns of the table here. SQL Concat function is equivalent to the concatenation operator (||). SQL concatenation operator is represented by double solid vertical bars or we can say double pipe signs. Question: How to concatenate more than two strings as SQL Concat that can have only 2 parameters and what is the difference between SQL Concat Function and SQL concatenation operator? The one answer for the second Question What is the Difference between SQL Concat Function and SQL concatenation operator? Is While SQL Concat function takes only two parameters, The Concat operator can be repeated as often as is necessary. Meaning, by the help of SQL Concat operator you can combine as many strings as you want. And Concatenation operator is also not supported by several databases such as SQL server so this might cause problem. To answer the first question How to concatenate more than two strings as SQL Concat that can have only 2 parameters? We will have to jump over SQL developer. Let's see some examples. Say we want to retrieve the full name of an employee from Employees table. Let's try it using SQL Concat function. SELECT Concat (first_name, last_name) AS "Full Name" FROM employees; Here in this query we use two column names - first_name and last_name as arguments of our Concat function Execute. As you can see here, we get full name of our employee but there is no space in between first name and last name. We will see how to format this string using SQL Concat function in a few seconds But before that, let's see how to do the same task using SQL concatenation operator. SELECT first_name ||last_name AS "Full name" FROM employees; As you can see this query also produces the same result. Now we will see how to format full name of employees First we will do this using SQL concatenation Operator. SELECT first_name||' '||last_name AS "Full name" FROM employees; Now you can see we get space between first name and last name of the employee. Again, let's do it using SQL Concat function. Here we will see the nested function concept where we will be using nested Concat function to achieve this formatted string. SELECT Concat (Concat (first_name, ' '), last_name) FROM employees; Inner Concat function has two parameters. These are our first column name first_name and an empty string which will be a space between first name and second name. This Concat will now return a string which is the first name with space. This returning string will be the first input of our Outer Concat and column last_name will be the second input. All together this will give us the desired output. As you can see this method is complex than the first one where we use SQL concatenation operator.

LNNVL FUNCTION IN ORACLE SQL
 
09:11
This video is the 5th video in the series of 'working with null', this video explains the working of the lnnvl function in oracle sql with simple and easy to understand example. LNNVL provides a concise way to evaluate a condition when one or both operands of the condition may be null. The function can be used only in the WHERE clause of a query. It takes as an argument a condition and returns TRUE if the condition is FALSE or UNKNOWN and FALSE if the condition is TRUE. LNNVL can be used anywhere a scalar expression can appear, even in contexts where the IS [NOT] NULL, AND, or OR conditions are not valid but would otherwise be required to account for potential nulls. Oracle Database sometimes uses the LNNVL function internally in this way to rewrite NOT IN conditions as NOT EXISTS conditions. In such cases, output from EXPLAIN PLAN shows this operation in the plan table output. The condition can evaluate any scalar values but cannot be a compound condition containing AND, OR, or BETWEEN.

How to find duplicate records in table sql
 
06:32
There are various times when we need to find duplicate records in SQL Server. It is possible to find duplicates using DISTINCT, ROW NUMBER as well as the GROUP BY approach. ------------- May be you like this -------------- umbraco playlist : https://www.youtube.com/watch?v=zoefdruzmGE&list=PLv0T7WlllnSnYRedhwL8x-atkVxrSdd3m Angularjs playlist : https://www.youtube.com/watch?v=KXjD1RiAz1U&list=PLv0T7WlllnSkCfNftTNY8tWqCFWT0sIMd jquery playlist : https://www.youtube.com/watch?v=jVncasz_iyw&list=PLv0T7WlllnSkkNahiiWu_GMXq49X5ccfe F Wcf playlist : https://www.youtube.com/watch?v=NB4k0RC6vl0&list=PLv0T7WlllnSmcGHacEQnLgKvitcJEsSl6 c# playlist: https://www.youtube.com/watch?v=ZrP0NKbsr8s&list=PLv0T7WlllnSl9pZWMaMGsyoAmqZtW4gM0 Duplicate records can create problems sometimes when displaying reports or performing a Multiple Insert update. Finding duplicate records in a database needs further investigation. In some cases, duplicate records are positive, but it all depends on the data and the database design as well. For example, if a customer has ordered the same product twice on the same date with the the same shipping and billing address, then this may result in a duplicate record.

Oracle INSTR Function
 
03:28
https://www.databasestar.com/oracle-instr/ The Oracle INSTR function allows you to search a string for the occurrence of another string, and return the position of the occurrence within a string. It’s helpful for finding if a string exists within another string. It can also be used for performing further string manipulation on, like substrings. The syntax of the INSTR function is: INSTR(string, substring [, start_position [, occurrence]]) These parameters are: string: The text string that is searched in. It’s usually the larger of the two strings. Mandatory. substring: The text to search for. It’s usually the smaller of the two strings. Mandatory. start_position: This is an integer value which indicates where in the string value to start the search. Optional, and the default is 1. occurrence: The occurrence of the substring to search for. Optional, and the default is 1, which means the first occurrence. Also, the searches performed by the INSTR function are case-sensitive. The value returned by INSTR is a number value, which is the number in the location of the string where the substring is found. The first character is 1. For more information about the Oracle INSTR function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-instr/

Loops in SQL Part - 1
 
25:45
A loop that executes an unlimited number of times. It encloses a sequence of statements between the keywords LOOP and END LOOP . ... If and only if the value of this expression is TRUE , the statements after LOOP execute. cursor_for_loop_statement. Issues a SQL query and loops through the rows in the result set. Writing Loops in SQL. In programming, a loop allows you to write a set of code that will run repeatedly within the same program. Many programming languages have several different types of loop to choose from, but in SQL Server there is only one: the WHILE loop TYPES OF LOOPS 1 SIMPLE LOOPS 2 CURSOR FOR LOOPS 3 WHILE LOOPS 4 NUMARIC FOR LOOPS A loop that executes an unlimited number of times. It encloses a sequence of statements between the keywords LOOP and END LOOP . With each iteration, the sequence of statements is executed, then control resumes at the top of the loop. An EXIT , GOTO , or RAISE statement branches out of the loop. At each iteration, the sequence of statements is executed and then control resumes at the top of the loop. 2. PL/SQL WHILE LOOP. Repeats a statement or group of statements while a given condition is true. It tests the condition before executing the loop body. Variables in SQL procedures (DECLARE, SET statements) ... Values can be assigned to variables using the SET statement or the SELECT INTO statement or as a default value when the variable is declared. Literals, expressions, the result of a query, and special register values can be assigned to variables. The WHILE loop test at the start of the loop and it the condition is false, the loop code is never executed. ... This is referred to as a REPEAT-UNTIL or DO-WHILE loop. PL/SQL does not directly implement a REPEAT-UNTIL loop however it is easy to construct one using an endless loop. The init step is executed first, and only once. This step allows you to declare and initialize any loop control variables. ... If it is true, the loop executes and the process repeats itself (body of loop, then increment step, and then again condition). After the condition becomes false, the 'for' loop terminates.

Using FORALL - VALUES OF with sparse arrays

FORALL offers a big performance boost over repeated execution in a loop of the same DML statement (different bind variables) - by binding an array. But what if the array is not densely filled? In that case, you should consider using VALUES OF (or INDICES OF, which will be covered in another video). ======================================== Practically Perfect PL/SQL with Steven Feuerstein Copyright © 2015 Oracle and/or its affiliates.

Using FORALL - INDICES OF with sparse arrays
 
06:44
FORALL offers a big performance boost over repeated execution in a loop of the same DML statement (different bind variables) - by binding an array. But what if the array is not densely filled? In that case, you should consider using INDICES OF (or VALUES OF, which will be covered in another video). ======================================== Practically Perfect PL/SQL with Steven Feuerstein Copyright © 2015 Oracle and/or its affiliates.

About Report Bursting: Oracle Reports enables you to deliver a single report to multiple destinations simultaneously. By taking advantage of this feature, you can create a single report, then send it in any format (layout driven formats, such as PDF or HTML, as well as data model driven formats, such as XML or delimited) to multiple destinations. You will modify a simple report we have provided to burst each group to a separate report. You will then modify a sample distribution XML file to send an e-mail to each destination with an attachment based on the separate reports. You will also send multiple e-mails to the same e-mail address with a single attachment (the entire report) Bursting on a Repeating frame: 1. Delete the parent (outermost) repeating frame. -in the Paper Layout -or, in the Object Navigator 2. Go to the Object Navigator. -Paper Layout -Select the main section node -Invoke its Property Inspector -Set the Repeat on property by selecting the repeating group on which the report will be burst. About Report Distribution: Report distribution enables you to design a report that can generate multiple output formats and be distributed to multiple destinations from a single run of the report. You can create distributions for an entire report, and for individual sections of the report. For example, in a single run of a report, you can generate HTML output, send a PostScript version to the printer, and also e-mail any or all sections of the report to a distribution list. Distributing a Report: 1. Define the distribution -Go to the Object Navigator -Paper Layout -Select the main section node -Invoke its Property Inspector -Click the Distribution property to invoke the distribution dialog box and set up the distribution list for that section. 2. Active the distribution -From the Menu -Select file -Click distribute or, on the command line, specify Distribute=yes.

SAS in 60 Seconds! - Removing duplicate data with SQL!
 
01:09
Bitcoin donations are welcome: 1GGV3gbJeA83FWmz9hDfPri8EuqcUtodXy SAS in 60 Seconds This video series is intended to help you learn how to program using SAS for your statistical needs. In this video I demonstrate how to quickly remove duplicate data from your datasets using the SQL procedure. Often, working with duplicated data can present complications in your analysis. For example, if you are running a simple linear regression model, you would want all observations to be independent and thus not have repeated measured (duplicate ID's). In this 1 minute video, I show you how to use the SQL procedure to quickly and easily remove duplicated observations. I also demonstrate how to use SQL to bring in all of the original variables as well. Today's Code: data main; input ID x y; cards; 1 2 3 2 3 4 2 3 4 3 4 5 4 5 6 5 6 7 ; run; proc freq data=main; table ID; run; * Create a dataset that selects only the unique ID's; proc SQL; create table temp as select unique(ID) from main; quit; proc freq data=temp; run;

How and When to Write SQL in PLSQL
 
01:01:17
Oracle PL/SQL makes writing SQL so darned easy -- in fact, it is way too easy to write SQL. As a result, PL/SQL developers take SQL totally for granted, and very few organizations have any sort of guidelines in place for when, where and how to write SQL. The result? The same or similar SQL statements repeated throughout the application, making it very hard to optimize and maintain the code. This webinar starts by reviewing the role of SQL in PL/SQL applications, and the key challenges involved when writing SQL. We then step through the most important best practices for SQL construction, ranging from avoiding SQL repetition to full qualification of variable and column names. After viewing this webinar, you will be well positioned to establish and follow a set of guidelines for SQL construction that will have a significant impact on application performance and maintainability. https://asktom.oracle.com http://www.plsqlchallenge.com http://www.oracle-developer.net/ http://oracle-base.com/ http://www.oracle.com/webfolder/technetwork/tutorials/plsql/sfdemo.zip http://goo.gl/FPG79Z http://stevenfeuersteinonplsql.blogspot.de/ https://twitter.com/sfonplsql
