Merge Statement in Oracle SQL with Example (UPDATE/DELETE or INSERT)
 
15:04
This video demonstrates how to write a Merge Statement in oracle sql, how it is useful in doing a conditional update or delete or both of them when the condition between the target table and source table is evaluated to true, and how we can insert the record into the target table when condition is evaluated to false. The video also shows the use of UPDATE, DELETE and INSERT with Merge, and also the various possible ways to use a Merge statement!!!

Oracle SQL Tutorial 12 - Intro to Constraints
 
06:13
As I believe I've mentioned in an earlier video, a constraint is basically a rule we can put in our database that prevents someone from putting the wrong data in. It protects our relationships and data integrity. Because the goal of these constraints are to protect our data integrity, you may hear them called integrity constraints. There are many integrity constraints we are going to talk about: NOT NULL UNIQUE PRIMARY KEY FOREIGN KRY CHECK There is also the DEFAULT attribute. These are all keywords we can add to our columns that will change the way the database works with our data and also prevents incorrect data. NOT NULL is a constraint you can put on a column that prevents nulls. A null is the absence of a value. When we say null, we are saying that every single row has to have a value for this column. UNIQUE is a constraint that makes every row have a unique value for this column. Now note, this does not require values to be put it, and it will allow multiple rows to be null. Next, we are going to talk about primary keys. What qualifies a column as a candidate key? First, not a single row should have a null for that column. Second, every row must be unique. The primary key constraint is essentially a combination of the NOT NULL constraint and the UNIQUE constraint. The foreign key constraint sets the requirement that any value in this column for any row must match a row in another column. Check constraints allow us to be more strict with what data is allowed in our database. NOT NULL and UNIQUE give some level of restriction, but what if we want something more specific? For example, what if we only want values between 0 and 100? That is where check constraints come in. When using check constraints, you give a boolean expression. A boolean expression is something that can be evaluated to true or false. It will only insert the row if the value you try to put into the row makes the expression evaluate to true. So if you put in a value too great or small, the expression will be false and the data is not allowed to be entered. The default constraint is a value you can give a column, and if for any reason when the row is created in the table a value is not provided, the default value will be given. So for example, we could have a bank account table where the balance defaults to 0. How do you actually implement these constraints when you are creating a table? In the next video we are going to be adding these to our users table.

Oracle SQL Tutorial 10 - Whitespace, Case Sensitivity, and Comments
 
07:48
SELECT "Hello World" FROM DUAL The first thing you should know about writing queries is that this SQL is not whitespace sensitive. That means we can space this out however we wish. The only requirement is that you do not separate keywords out with spaces. They must be as one entity. Another gotcha is that when you are inside of quotes, whitespace becomes very important. That means if inside of a string you put a character and then 10 spaces, every single one of those spaces is going to part of that string: SELECT "Hello World" FROM DUAL The next thing you should notice is the capitalization. When we type SQL, by convention we capitalize all keywords. I personally really like this because you can easily see the difference between keywords and words that we created or use. But obviously we could capitalize the letters in the quotes. Keep in mind that this is a convention, meaning you do not have to follow this. Oracle is also case insensitive in that SELECT and select both do the same thing. Strings, once again, care about casing. Take this, for example: SELECT 'true' FROM DUALWHERE 'Hello' = 'Hello' And compare the results to this: SELECT 'true' FROM DUALWHERE 'Hello' = 'hello' Only the first one outputs the value true. Once we get into creating database objects such as tables with columns, those are not case sensitive either. That means instead of selecting from DUAL, you can select from DuAl Finally, I shall introduce you to comments. Comments allow you to tell the database engine that you want it to ignore a certain part of your code and not execute it. This is helpful if you want to document your code. It is also useful if you want to have multiple SQL statements open in one tab, but don't want to hover over the one you want to execute. You can comment out the ones you are not using and uncomment them when you are done. Using – will comment out the rest of the line, Using /* */ will comment everything between. This can even be used over multiple lines.

R tutorial: connecting to a database
 
03:38
Learn more about connecting to databases with R: https://www.datacamp.com/courses/importing-data-in-r-part-2 Welcome to part two of importing data in R! The previous course dealt with accessing data stored in flat files or excel files. In a professional setting, you'll also encounter data stored in relational databases. In this video, I'll briefly talk about what a relational database is and then I'll explain how you can connect to it. In the next video, I'll explain how you can import data from it! So, what's a relational database? There's no better way to show this than with an example. Take this database, called company. It contains three tables, employees, products and sales. Like a flat file, information is displayed in a table format. The employees table has 5 records and three fields, namely id, name and started_at. The id here serves as a unique key for each row or record. Next, the products table contains the details on four products. We're dealing with data from a telecom company that's selling both with and without a contract. Also here, each product has an identifier. Finally, there's the sales table. It lists what products were sold by who, when and for what price. Notice here that the ids in employee_id and product_id correspond to the ids that you can find in the employees and products table respectively. The third sale for example, was done by the employee with id 6, so Julie. She sold the product with id 9, so the Biz Unlimited contract. These relations make this database very powerful. You only store all necessary information once in nicely separated tables, but can connect the dots between different records to model what's happening. How the data in a relational database is stored and shuffled around when you make adaptations, depends on the so-called database management system, or DBMS you're using. Open-source implementations such as MySQL, postgreSQL and SQLite are very popular, but there are also proprietary implementations such as Oracle Database and Microsoft SQL server. Practically all of these implementations use SQL, or sequel, as the language for querying and maintaining the database. SQL stands for Structured Query Language. Depending on the type of database you want to connect to, you'll have to use different packages. Suppose the company database I introduced before is a MySQL database. This means you'll need the RMySQL package. For postgreSQL you'll need RpostgreSQL, for Oracle, you'll use ROracle and so on. How you interact with the database, so which R functions you use to access and manipulate the database, is specified in another R package called DBI. In more technical terms, DBI is an interface, and RMySQL is the implementation. Let's install the RMySQL package, which automatically installs the DBI package as well. Loading only the DBI package will be enough to get started. The first step is creating a connection to the remote MySQL database. You do this with dbConnect(), as follows. The first argument specifies the driver that you will use to connect to the MySQL database. It sure looks a bit strange, but the MySQL() function from the RMySQL package simply constructs a driver for us that dbConnect can use. Next, you have to specify the database name, where the database is hosted, through which port you want to connect, and finally the credentials to authenticate yourself. This is an actual database that we're hosting, so you can try these commands yourself! The result of the dbConnect call, con, is a DBI connection object. You'll need to pass this object to whatever function you're using to interact with the database. Before we do that, let's get familiar with this connection object in the exercises!

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

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/

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.

Best Way to Write Basic SQL Queries
 
13:33
SQL Server Query writing strategies is something I have yet to find in any book. When enthusiastic SQL students do this, they experience a revelation. The number of errors drops significantly and the speed at writing complex queries increases immediately. Knowing how to narrow down what we are looking for amongst a vast list of choices helps immensely. Grabbing the right tables first and then the fields second is akin to grabbing the right menu before ordering an item from it. In fact, one student named Tim took this back to his team of SQL developers and they immediately implemented this process. We are all used to following steps. Most of the time, actions are sequential from top to bottom or left to right. Other times we complete things in phases. The two phases we are going to use in this exercise apply to joining tables. This is easy to implement as we only need remember to organize first and clean up second. When visiting a new restaurant, we will ask to see the menu, because we want to see all they have to offer. The odds are that we might be interested in half of the items, but only need a few dishes for our group at the table. Looking at the menu is like starting a query with a ‘SELECT *’ statement. Once we have looked at all the fields, we narrow our choice(s) to only the items we want at the time. Sometimes restaurants have multiple menus. My favorite restaurant has a kids’ menu, an adult menu, a gluten-free menu and a drink menu. These menus were each gathered at our table. Ultimately, in my head, a selection was narrowed to what was needed. Phase I: Organize. When building a new query from many tables, we often find ourselves wondering, “Where do I start?” First, lay the steps out by identifying which tables contain the essential data. Second, get all the table joins working with a basic ‘SELECT *’ statement. Third, add any basic filtering criteria. Phase II: Itemize. Once all joins and criteria, such as SELECT, FROM and WHERE are working, we are ready for Phase II. This entails going back and changing our ‘SELECT *’ to an itemized SELECT field list as the final step. Let’s explore how this two-phase process of Organize and then Itemize can be a big time-saver. We are going to use one of the challenges from the last lab. In Lab 3.2 (Outer Joins), Skill Check 2, we needed to get four fields from two different tables. If we were to list all four desired fields and test one table at time, we will get an error as seen on the right side of the figure below. In the figure below we write a SELECT statement and part of the FROM clause. When completed, the FROM clause will have two tables, but for now we just want to get the Location table working. By using the ‘SELECT *’ strategy, we remove any possible errors from line 1. From there, we can focus on the more complicated logic used for joining tables together. We can add tables one at a time until everything is working. This is the Organize phase. NOTE: SELECT * never results in an Error message stating “invalid column name”, however; a SELECT list with itemized field(s) can have this error. After our query is organized and working, we can go back and itemize the SELECT field list to display only the fields that are necessary. This is done during Phase II (Itemize). The steps for this system are broken down as follows: Since SELECT is always the first statement in a query, it’s natural to want to write the field names before writing the FROM clause. However; we can save time and trouble by using the ‘*’ until the entire query is working properly. When this is complete, it is very easy to itemize the field list, with the confidence of knowing it will not cause any problems. Exercise: Simple membership for a club: Table1 (id_Member,name_Member, email_member, title, age, company) Table2 (id_Club,club_name, club_Location, address) Table3 (id_club, id_member,membership_date) Q1: Show all member names, email, age, and company from Table1 Q2: Show all club name, location, and address data Q3: Show member name, club name, club location (hint: Use joins and all 3 tables) You can find all other classes related to this video here: http://www.joes2pros.com/joes2pros/Course/Introduction_To_Microsoft_SQL_Server Enroll Today & Get the First Month for only $1!

What is Exists / Not Exists Logical Operator in SQL Server Exists returns TRUE if a subquery contains any rows. EXISTS is used when we want to test for the existence of rows specified by a subquery. 1) EXISTS will return TRUE if subquery contains any rows. That is right, if our subquery will return any rows and we have used EXISTS, the outer query is going to return all rows. 2) Use EXISTS and Join with SubQuery Link to scripts used in SQL Server / TSQL Tutorial Video http://www.techbrothersit.com/2016/06/how-to-use-exists-logical-operator-in.html Check out our website for Different SQL Server, MSBI tutorials and interview questions such as SQL Server Reporting Services(SSRS) Tutorial SQL Server Integration Services(SSIS) Tutorial SQL Server DBA Tutorial SQL Server 2016 DBA Tutorial SQL Server / TSQL Tutorial ( Beginner to Advance) http://www.techbrothersit.com/

Oracle 12c PL/SQL Security Enhancements - Session 2 of 8- Tutorial Agenda
 
04:11
What's in the SkillBuilders Oracle 12c PL/SQL Security New Features tutorial. John Watson: What I want to talk about today is some security issues with 11g PL/SQL and then moving on to Oracle Database 12c. [see how they've been addressed] In general previous releases of the database have had real problems with security particularly with PL/SQL. This does cause a bit of confusion out there when you read third party assessments contrasting Oracle security with say SQL server and so on. Some people will say that Oracle security is rubbish. Other people will say it's fantastic. What causes that paradox? It's because you can secure your database, but you have to do it. Out of the box the database is stuffed full of marvelous facilities - the developer's marvelous facilities for users - but many of them are potentially highly dangerous. So make no mistake. Oracle database can and should be totally secure, but if your DBAs and your programmers don't make it secure it may be wide open to abuse, wide open to hackers. This has always been a problem. With later releases 11 and now 12, the situation is improving. There are more and more things that one can do declaratively, more techniques for tightening up those wonderfully powerful facilities that can be open to abuse. So what I'm going to go through is spend some time with 11g. We have to. We have to understand what some of the problems are that are being addressed. Also, of course, 11g will be available to be useful for several years to come. I'll spend some time in 11g environment looking at some of the major issues in the PL/SQL environment. Then we will move on to 12c and see some of the new facilities and see how they tighten up the security issues that we see with 11g. If possible - I don't know if this will come true or not - I'll maybe have quick look at network access control list I completely re-implemented in 12c and maybe talk a bit about the advanced security option as well as that has changed somewhat too. That's the agenda I intend to follow. Beginning with 11g, we'll go through what are the definer's rights, what are invoker's rights for code, the relationship between roles and PL/SQL. These issues, definer's rights, invoker's rights and roles is potentially very useful but cause a lot of confusion. I remember when I installed PL/SQL, it first came when it was first introduced in version 7 many, many years ago I found this mind bogglingly confusing. Invoker's rights came in a couple of releases later and then died. That added to the confusion because invoker's rights attempted to fix the problem caused by definer's rights. Roles have always been confusing in the PL/SQL 11g environment. We then move on to the 12c techniques. It's a whole new privilege - inherit privileges or inherit any privileges. That tightens up some of the problems with both views and with PL/SQL. They're very nice facility indeed. We can now grow up roles to procedures, so the confusion of roles in PL/SQL, that is not removed, but we can use roles in a much more [03:31 inaudible] fashion with PL/SQL in 12c. Also, closer [03:35 inaudible], that's the concept of the bequeath view. Just as PL/SQL stored procedures they execute definer's rights to invoker's rights with the privileges of the person who owns the PL/SQL or with the privileges of the person who invokes the PL/SQL. It's the same with views. Historically views are always executed with the privileges of the owner. Now, to a certain extent we can have what I might always call an invoker's rights view. Then if we have time, a couple of other things as well.

http://www.gcreddy.com/2017/06/sql-operators.html SQL Operators, Arithmetic Operators, Comparison Operators, Compound Operators, and Logical Operators. SQL Operators examples with SQL Where clause to form single and multiple Conditions. An operator is a reserved word or a character used primarily in an SQL statement's WHERE clause to perform operation(s., such as arithmetic, comparisons and Logical operations. Operators are used to specify conditions in an SQL statement and to serve as conjunctions for multiple conditions in a statement. Important Categories of SQL Operators are, 1. Arithmetic operators 2. Comparison operators 3. Logical operators Etc... ----------------------------- 1. Arithmetic Operators: Arithmetic operators can perform arithmetical operations on numeric operands involved. 2. Comparison Operators: A comparison (or relational. operator is a mathematical symbol which is used to compare between two values. Comparison operators are used in conditions that compare one expression with another. The result of a comparison can be TRUE, FALSE, or UNKNOWN (an operator that has one or two NULL expressions returns UNKNOWN.. 3. Logical operators: There are three Logical Operators namely, AND, OR, and NOT. These operators compare two conditions at a time to determine whether a row can be selected for the output. When retrieving data using a SELECT statement, You can use logical operators in the WHERE clause, which allows you to combine more than one condition.

CASE Function( IF..THEN..ELSE) in SQL ORACLE Query With Example
 
04:03
ORACLE/PLSQL: CASE STATEMENT The Oracle/PLSQL CASE statement has the functionality of an IF-THEN-ELSE statement. Starting in Oracle 9i, you can use the CASE statement within a SQL statement. The syntax for the Oracle/PLSQL CASE statement is: CASE [ expression ] WHEN condition_1 THEN result_1 WHEN condition_2 THEN result_2 ... WHEN condition_n THEN result_n ELSE result END --------- ARGUMENTS: expression is optional. It is the value that you are comparing to the list of conditions. (ie: condition_1, condition_2, ... condition_n) condition_1 to condition_n must all be the same datatype. Conditions are evaluated in the order listed. Once a condition is found to be true, the CASE statement will return the result and not evaluate the conditions any further. result_1 to result_n must all be the same datatype. This is the value returned once a condition is found to be true. NOTE: If no condition is found to be true, then the CASE statement will return the value in the ELSE clause. If the ELSE clause is omitted and no condition is found to be true, then the CASE statement will return NULL. You can have up to 255 comparisons in a CASE statement. Each WHEN ... THEN clause is considered 2 comparisons. Lets apply this function on emp table. Emp table has 3 dept numbers like 10,20 and 30. So if I want to display the different dept names based on ID, I have to use IF THEN ELSE condition. IF deptno=10 THEN "DEPT1" ELSE deptno=20 THEN "DEPT2" ELSE deptno=30 THEN "DEPT3" This entire IF block can be achived using CASE. CASE deptno WHEN 10 THEN 'DEPT1' WHEN 20 THEN 'DEPT2' WHEN 30 THEN 'DEPT3' ELSE 'NO DEPT' END; Query used in Video: select empno,ename,deptno,CASE deptno WHEN 10 THEN 'DEPT1' WHEN 20 THEN 'DEPT2' WHEN 30 THEN 'DEPT3' ELSE 'No Dept' END from emp;

More Performance from SQL Server and Other Databases
 
12:42
The title is a bold statement, but a true one. It’s true for SQL Server, MySQL, Oracle, MariaDB, and basically, pretty much any database you run in a Windows operating system. Yes, it’s true that one can achieve better performance from databases in a myriad of different ways, ranging from better structuring of tables and indexes, improving the efficiency of queries, occasionally reindexing, and so on. But, Condusiv’s V-locity software is much easier than that. You just download a copy and have it running within a couple of minutes. There are no code changes required, no reboots, and absolutely no disruption to any live running workings – whatsoever!

Demonstrating Oracle DB Elapsed Time and Wall Time With Parallel Query
 
03:37
Is it really true? In my recent postings I wrote that when using parallel query a SQL statement's wall time is roughly equal to its elapsed time divided by the number of parallel query slaves. To check I ran an experiment and posted the results. The results are both obvious and illuminating. If you don't want to read but just sit on the couch and watch a video, you're in luck! I created a special video clip demonstrating what I wrote about. The main video clip is from my OraPub Online Institute video seminar, Tuning Oracle Using An AWR Report - Part 1. (NOT Part 2 as the video shows) From my blog posting: http://blog.orapub.com/20140907/watch-oracle-database-elapsed-time-and-wall-time-with-parallel-query.html For more information on OraPub r for more great education, go to www.orapub.com
