Oracle FROM_TZ Function
 
01:45
https://www.databasestar.com/oracle-timezone-functions/ The Oracle FROM_TZ function is used to convert a value in a TIMESTAMP data type, and a specific TIME ZONE, to a TIMESTAMP WITH TIME ZONE value. It’s a helpful conversion function if you work with times and time zones a lot. The syntax of the FROM_TZ function is: FROM_TZ ( timestamp_value, timezone_value ) The parameters of this function are: - timestamp_value: the value in a TIMESTAMP format to convert. - timezone_value: this is the timezone value that the timestamp_value will be converted in to. If you want to know what values can be used as a timezone value, you can look in the database view here: SELECT * FROM v$timezone_names; For more information about the Oracle FROM_TZ function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-timezone-functions/

On daily basis, we come across this scenario when we have to find out if a column exists for a Table or View in Database. Specially if we are debugging SQL Server Reports/An application, we take a column name or part of it and want to know that from which table this column is used. We can query INFORMATION_SCHEMA.COLUMNS view to get this information. blog post link for scripts used in this video http://sqlage.blogspot.com/2014/01/tsql-how-to-check-if-column-exists-for.html

Evidence Ancient Aliens Planned Humanity
 
07:06
Was earth visited in the past by Ancient Aliens flying UFOs around and telling there where to build their cities....perhaps hoping that one day in the future we would put together the clues? An uncanny and what seems to be a planned alignment of a multitude of ancient archeological sites around Earth strongly points towards humans of the past being guided, globally, and over many millennia by some sort of higher intelligence. Personally, my mind was absolutely blown once I manually connected all the sites on Google Earth myself, which is exactly what I’m about to do for you. At the end of the video, I expect your mind to be blown just as mine was. I also encourage you to try this out for yourself in Google Earth and replicate my results. Before we begin, please forgive me for butchering some of these names. Nearly all of these sites are considered what is known as a UNESCO World Heritage Site, sites that are of extreme special cultural or physical significance. 1) Easter Island: We’re going to start off with Easter Island, which is home to the mysterious Moai statues which were created around 800 years ago for reasons that still remain unknown. A total of 887 monolithic stone Moai statues have been counted. 2) Nazca Lines: The Nazca Lines are mysterious giant glyphs carved into the ground in the Nazca Desert of Peru. They were thought to be built around 1600 years ago - no one knows why they are there as they can only be seen from the sky...why would anyone do that when flight hadn't been invented yet? 3) Machu Picchu: Machu Piccu was built around 600 years ago at the height of the Incan Empire and allegedly as a means to honor a "sacred landscape." If you havn't heard of it before, it's a city literally built on top of a mountain by hand….with rocks sometimes weighing as much as 40 tons. 4) Tassili n'Ajjer Tassili n'Ajjer is a range of mountains in Algeria in the Sahara Desert. It contains some 15,000 ancient cave drawings some of which are up to 10,000 years old. Some of the carvings are a bit strange as well. 5) Persepolis Persepolis is the ancient capital of Persia. It was built around 2500 years ago. 6) Khajuraho Group of Monuments The Khajuraho Group of Monuments are 85 special temples to honor Hindu gods built around 1000 years ago. They were allegedly built in this area as it is an area where quote “the gods love to play” according to local legend. The temples are dedicated to various Hindu gods such as Shiva, Vishnu, Ganesha, and Jain Tithanks. 7) The Oasis at Siwa The Oasis at Siwa is estimated to be around 4,600 years old..and many believe it could be much older. It is famous for being the home of the Oracle of Amun. Amun was an Egyptian Diety. Alexander the Great believed that his divinity was a result of his visit to this oracle. 8) The Pyramids of Giza I'm sure you've heard of the Pyramids of Giza before. They were estimated to have been constructed around 4,600 years ago. 9) Mohenjo Daro Mohenjo Daro was built in around 4600 years ago. It is part of the ancient Indus Valley Civilization. The name literally translates to the Mound of the Dead. It is thought to be one of the world's earliest major urban settlements. 10) Angkor Wat Angkor Wat was built around 1000 years ago and was dedicated to the god Vishnu. According to a 13th Century Chinese traveler, it was allegedly believed that the temple was contructed in only one night by an architect of divine power. Now let’s complete our journey by connecting the final destination to our original one, Easter Island. Once we zoom out….do you see a pattern? ALL of these sites line up on the same line around the Earth. The line is, except for a few very minor deviations that may be due to the Earth slightly shifting over the many millenia these sites were constructed as well as perhaps partial user error on my part mapping these out…..perfect. It almost looks like an equator. The probability of this occuring by chance is basically zero. Why do all these ancient and quite important sites line up on the same line on Earth? Was someone guiding the construction of all these ancient sites? Why are so many if not all of the sites related to something divine….and what was that divinity? In order to orchestrate such a thing, these civilizations would have somehow had to have made contact with each other across the space of the entire planet as well as over the course of several millenia in addition to being able to basically see the Earth from space in order to create such an uncanny alignment. These arn't the only sites that line up either, there's quite a few more sites that line up as well as you can see here. I only cut some out for the sake of brevity. Once again I encourage you to try this out for yourself. Also, if you know of any mysteries you’d like me to cover in upcoming videos, leave a comment below or send me a message on Youtube.

Oracle NVL2 Function
 
03:05
https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/ The Oracle NVL2 function is an extension of the NVL function and can be used to handle NULL values. It allows you to specify a value to check for NULL, a separate value to return if the value is NULL, and another value to return if the first value is not NULL. It’s very similar to NVL but allows for more flexibility. The syntax for NVL2 is: NVL2( value_to_check, value_if_not_null, value_if_null ) What are these parameters: Value_to_check is the value the function checks to see if it is NULL. Value_if_not_null is the value to return if the first value, value_to_check, is not NULL. Value_if_null is the value to return if the first value, value_to_check, is NULL. These parameters can have almost any data type (the second and third parameter can’t be a LONG data type). Oracle will determine the data type from the supplied parameters. There are quite a few of these conditional checking functions in Oracle, so the one to use would depend on your needs. But it’s good to know this function exists. For more information about the Oracle NVL2 function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/

Oracle 12c Database New Features - Pluggable Database - Video 1
 
17:25
Oracle 12c Database New Features - Pluggable Database - Video 1 1. Pluggable Database * Oracle 12c introduces a new feature called 'Pluggable Database'. Here Oracle Metadata and user data are totally separated into two sections. One is Container DB (or CDB) which will hold Oracle Metadata. The other is Pluggable DB (or PDB) which will hold user data. How does a Pluggable Database work? In the regular database, Oracle's metadata and user's application data are integrated. For beginners, Oracle Metadata is the data that is present when you install a new Oracle Database (without any sample schemas). Even though it can be called as an empty database, it still has data provided by Oracle. This data is needed by the database to function. For example, the objects owned by SYS, SYSTEM are mostly metadata. Then user data is entered into that database. They will go under multiple user schemas. Now the database is being used by the users. Now a situation arises so that we need to create another database on the same server. Why? Let us say that you need to provide data to two clients. And you don't want one client to other's data. And your data is contained in an extensive set of application schemas. In this case, making a copy of those applications schemas into a different set of names and making them reside in the same database is very difficult. So, you provide two separate databases. This also ensures that there is no security violation. So, we install another new database, which comes with Oracle Metadata. Then we load the user data. In this method, which is currently being used (Year 2013), there will be a need for more memory for both the database instances. There will be two SGAs, two sets of smon, pmon and other background processes running. Then if we need to copy one database to another, we need to rely on extensive procedures which includes exporting the data from the source database first, then removing the data at the target and then finally loading the data in there. After that, we need to take care of the user security and object privileges etc. So, if you want to provide data for multiple tenants, that is multiple clients, then with the current set of features (till Oracle 11g), we have to create multiple databases. That is, one database for one client. In otherwords, there is no multi-tenancy. Multi-Tenancy is becoming an important requirement in cloud infrastructure, these days. You would like to have the ability of providing data to multiple clients from the same database system with full confidence in security. This can be achieved in Pluggable Database. In a Pluggable Database, Oracle basically separates its metadata entirely from the user data. Metadata is stored in a section called Container DB. Then the user data are stored in Pluggable DBs. It also stores user metadata in the Pluggable DB. By the way, what is user metadata? For example, earlier, the list of user accounts that exist in a database is tightly inegrated with Oracle Metadata. Now, with the separation of Container DB and Pluggable DB, the user accounts must exist in the Pluggable DB. So, the Pluggable DB not only contains user data, but also some user metadata. So, what are the benefits? * Multi-Tenancy - We can bring in two Pluggable DBs under one Container DB. Both will be totally segregated, but yet controlled by one instance. This is an important feature for SaaS (Software as a Service) platforms, Cloud, On-Demand and Vendor Managed Application solutions. * Easy cloning/copying. Now the cloning and copying the databases across servers would be much easier. Just clone a Pluggable DB and plug-it-in in a different server. * Very easy upgrades and patching.

Talk about what I like and shit? I would try it if she wasnt so damn perfect Damn I so tired of being nervous Shouldn't even talk about the way you glance at me at lunch Cuz I know it's nothing, but damn it's been givin me a hunch Makes me want to think of a cute little fantasy of us But I can't hear you call for me, i've never heard you speak in tongue Just another reason, lust isn't what i’ve been thinkin I wanna get to know you but i'm standin over here shakin It's makin me aggravated cuz I think I know what to say I just don't quite know how to phrase it I'm thinkin i’ll overthink it Maybe I should just say “Nevermind” and screw it Cuz if I finally do it and you dont like me, I'm ruined It might be just stupid to get up and say “Hi” so i'm through it I guess i’ll sit here in silence with you in my mind where you’re clueless ---------------------------- - Join my music Discord: https://discord.gg/fanWMpy - Instagram: https://www.instagram.com/oraclemusicofficial - Soundcloud: https://soundcloud.com/official_oracle - Beat Credz: https://www.youtube.com/watch?v=_5h2Pau7sKU - Art Credz: Me

Oracle 12c PL/SQL Security Features - Lesson 4 of 8 - Roles and PLSQL
 
06:21
Learn how Roles really work with Oracle PL/SQL and why a privilege granted via a role can't be used in PL/SQL. Demonstrations, examples. See all lessons and many more free Oracle Database tutorials at https://www.skillbuilders.com/free-oracle-database-tutorials John Watson: We have the business of roles - roles and PL/SQL. The point here is that roles are invisible to PL/SQL. When you compile your code, only direct privileges are available. When you run your code, only direct privileges are available. This is for definer's rights, I should say. When you run the code, only direct privileges are available to grant to the definer. In effect, the definer's rights code, all roles are disabled within the stored procedure. And certainly roles are disabled when compiling the code. Functionally, it's equivalent to having issued the command SET ROLE NONE. Why is this? Why is it you can't use your privileges? It's perfectly straightforward. It's a technology limitation. Quickly to see what's going on. If I go in and say - let me connect or create a clear schema. I'll create myself, grant dba to jw identified by jw. I've created a user and given him ridiculously high privileges. Connect.... What can you do? You can do pretty much anything. If he wants to delete from scott.emp, he can do it. Let's roll back, because along with his dba role, he has the ability to pretty much anything to use the data. Now we'll create a procedure. If I create a procedure, create delemp as begin, and in there I delete from scott.emp, end, compilation errors. What are they? Show error. At line 2 table of view doesn't exist. That's line 2 delete from scott.emp. I remember way back in version 7, this cause so much confusion before we realized what was going on. It's quite simple that when we are within the code, as the definer or the invoker, because this is definer's rights code, when we are within the definer's rights code block or indeed when we are compiling a definer's rights code block, the roles are disabled and that's why we cannot see it. But why is this and why do I say it's a technology limitation? It's because roles can be enabled and disabled. They can be enabled or disabled. That makes it logically impossible to consider a role when executing a stored procedure because I might have the role enabled while I compile it, but how do I know that it's going to be enabled when I run it? If I grant execute on the code to a third party, he doesn't have the role at all and that he must not even be logged on. So it becomes a logical impossibility because of the way roles are used because roles are enabled or disabled. You can dynamically switch them on and off. It's a logical impossibility to use role within definer's rights program module. Invoker's rights code, however, is very different. That infuses some interesting issues. Invoker's rights code can use any roles that happen to be enabled for the user at the time that he invokes it in exactly the same way that an anonymous PL/SQL can use any enabled roles. In the security point of view, the definer can in effect grab any roles within his code that the invoker happens to have. Dave: [Question], John, pardon. How do you enable or disable a role? John: Right now there's several techniques. I won't spend too much time demonstrating. The easiest technique will be alter - I can set role none. And that will have disabled all my roles. Now if you look at this, I've got nothing. If I try to run my code and query - let's see. Yes. If I try to delete from scott.emp I can't see it. So I'll set role dba and now of course I can. That's the easiest way. In fact, there are much more [05:07 inaudible] ways to switch roles on and off. We can do it with operating system authentication and I can do it with proxy authentication. We have a persistent session through application server as well as a user when we pass that session out to many of the users that can switch roles on and off. That's the persistent session switch identities. Perhaps, best of all, I can create what I call secure application roles well it protect the role with a package and that can contest any number of issues - environment variables, maybe the time, maybe your IP address, perhaps the program you're using and switch roles on and off accordingly. So there are many ways for controlling roles and you should do it. Blindly granting roles and letting them be enabled all the time is not good security. The end result for this, however, you can get some pretty unexpected results within your code. I've tried to run through in our first half hour some of the issues that we see with PL/SQL in release 11g and earlier. After a short break, we'll move on to the 12c features.

Either way, you probably know this world-is-a-computer-simulation sci-fi series by its slo-mo bullets, screens full of green text, and a whole lot of Keanu Reeves making his "serious face." What you might NOT know about the Matrix is that the main character, Neo, is not actually the savior of the world and acts is actually just a pawn throughout the entire series meant to throw off you and almost everyone else in the movie. But that begs the question: If Neo isn't the ONE, who IS? Like the theme song?

Sql - Insert if not exists query
 
00:36
sql insert if not exists In many cases we need to insert a row by checking whether it is already available or not. First we need to find a row is present or not. then if it is present, we skip the insert process. If the row is not present, then we insert the row. This query will help to insert rows only if not present. You can use this query directly in your application, where you need to check the presence before insert. The syntax is : merge into tblname i using (select ‘val1' as a1,‘val2' as a2,‘Val3' as a3, …. , ‘valN' as an) d on i.attribute1=d.a1 when not matched then insert (Attribute1,Attribute2,Attribute3, …. , AttributeN) values (d.a1,d.a2,d.a3,…,d.an); The example is merge into items i using (select '7' as itemid,'puri' as itemname,'25' as itemcost) d on d.itemid=i.itemid when not matched then insert (itemid,name,price) values (d.itemid,d.itemname,d.itemcost); Like us on FB https://www.facebook.com/Eddy5SmartSolutions/?fref=ts Subscribe Our Channel https://www.youtube.com/channel/UCtUgeNnytvnb51p25pcz58g

Leveraging Oracle Multitenant from Visual Studio and .NET
 
10:08
.NET developers: Watch this video to learn how to take advantage of Oracle Multitenant, a new feature of Oracle Database 12c, while using Visual Studio. Oracle Multitenant makes it easy for developers to quickly make copies of existing databases, create/destroy new test databases quickly, and to share databases with other developers. If you would like to try out what you see in this video you will need access to an Oracle Database version 12.1 or later that was configured to use a container database. You will also need to download and install: 1) Oracle Developer Tools for Visual Studio version 12.1 or higher 2) Oracle Data Provider for .NET version 12.1 or higher This software can be found on the .NET Developer center (http://otn.oracle.com/dotnet) as part of the "ODTwithODAC" download packaging. For instructions on how to install this, see the Quick Start Video: https://www.youtube.com/watch?v=zrzDOk8gg5A Visual Studio 2012 and 2013 is supported - any edition except Express Edition (Community Edition is supported). Oracle Multitenant, introduced in Oracle Database 12c Release 1 (12.1), enables an Oracle database to function as a multitenant container database (CDB) that includes zero, one, or many customer-created pluggable databases (PDBs). A PDB is a portable collection of schemas, schema objects, and nonschema objects that appears to any Oracle client application as a non-CDB. Note: all Oracle database versions prior to Oracle Database 12c Release 1 (12.1) are known as non-CDBs. A CDB contains one seed database, which is a system-supplied template that the CDB can use to create new PDBs. The seed PDB is named PDB$SEED. You cannot add or modify objects in PDB$SEED. Because new PDBs are essentially copied from the seed rather than created from scratch, PDB creation time is generally much faster than creating a non-CDB. PDBs can also be cloned from other PDBs in a similarly fast amount of time. PDBs can be unplugged, which means they are removed from the CDB, and exist on the database server simply as a set of files: a metadata XML file along with some database files (.DBFs). This combination of metadata file and database files can then be easily plugged into any other CDB that is compatible with the PDB. From the point of view of .NET developers who have SYSDBA privileges, this makes testing a database configuration with your application as simple as cloning an existing PDB, or plugging in a PDB in the form of some provided database files. Similarly, a database configuration can be shared with other developers, either by cloning or through unplugging and sharing the database files. If a user with SYSDBA privileges makes a connection to a CDB in Visual Studio Server Explorer, a Pluggable Databases Node appears in the tree control. When that node is expanded, the seed PDB, along with any other available PDBs, appear as child nodes. From there, operations such as Create New, Plug, Unplug, Clone, Delete, Open, and Close can all be easily achieved.
