Importing Data from Excel into Oracle Database using SQL Developer 4.1
 
02:23
One of SQL Developer’s most popular features has undergone a significant upgrade. Users can quickly define and recall delimited or Excel files to be imported to a new or existing Oracle table. Data preview and validation is provided for each column, as well as ‘best guess’ data type and date format mask mapping. This process can now be automated via the SQL Developer command line interface (SDCLI) ‘Import’ command. NOTE: This is a video only. There is no audio. Copyright © 2015 Oracle and/or its affiliates.

MySQL 27 - TEXT, TINYTEXT, MEDIUMTEXT, LONGTEXT
 
03:42
The TEXT data types have not yet been discussed, but they are another string data type. They are similar to the VARCHAR data type with some minor differences that are important to know. The first thing to note is that there are four versions used to determine different sizes. From least to greatest size is TINYTEXT, TEXT, MEDIUMTEXT, LARGETEXT. These each have different maximum byte sizes: 255, 65535, 16 million something, and 4 billion something. You create a column as one of these data types just as you would with a varchar column. You work with them exactly the same, too. If that is the case, what are the primary differences between these and VARCHAR? The first difference is that VARCHAR is restricted by the row limit of a table. TEXT tables do not contribute nearly as much (max of 12 bytes) because the data is not stored inline in the table. This means that if you need to allow for extra space for other rows, you can use a TEXT column. And even though the table only contains a pointer to the data, it is all hidden to us and working with a TEXT column is the same as working with a VARCHAR column. The second primary difference is that TEXT data types do not allow for a default other than NULL. Thirdly, VARCHAR is limited to just under 64KB, whereas you can use MEDIUMTEXT or LARGETEXT to allow for more storage. So if what you are trying to store as an individual value is over 64KB, use a text column. Other than those three things, VARCHAR will usually work just fine for our text needs. Now, last thing is that these data types are often called CLOB data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Java JDBC Tutorial – Part 10: BLOB - Reading and Writing BLOB with MySQL

Welcome back to another tutorial on Java JDBC. In this video we're going to learn how to read and write BLOBs. For this tutorial we're going to use the employees table. I have a SQL script that will create the table and add sample data for you. You can download it from the link below. The file is sql/table-setup.sql. Time - 00:28 So what exactly is a BLOB? Well a BLOB is basically binary data that we store in the database. You normally use BLOBs to keep track of documents, images, audio, or any other binary object that you have. Note that not all databases have support for BLOBs. In this example we’re going to make use of MySQL and they have BLOB support. Time - 00:48 On this slide we will learn how to create a BLOB column. So when we create a table in MySQL we add a column with the BLOB data type. On this slide I want to learn how to write a BLOB to a database. For this example I'm going to add a resume for an employee. I'm going to read a local PDF file and I'll take that file and update the database with the binary data that's the actual content of PDF file. Let's walk through the code. Time - 01:17 At the beginning I’ll set up a SQL statement. I’ll say update employees set resume equals to question mark where the email address equals [email protected] We’re only going to make a change for this John Doe employee, set up a prepared statement, and then I go, we’re going to create a file that's an actual handle to the local file sample_resume.pdf. Then I’ll set, on my statement I’ll set the binary stream, that first parameter for the resume comma the input. That's the input stream I have for that file. Then I actually call my statement .executeUpdate. That will actually update the database with the binary data. Time - 01:54 All right so let's switch over to Eclipse and let’s look at a very simple demo. I have a program called WriteBlobDemo. In this program we're going to actually read a resume from a local file system and write it as a BLOB to the database. I’ll walk through the code here. The first thing we do is we get a connection to the database. We prepare a statement. We're going to update employees, set resume equals to question mark where email equals [email protected] So we’re going to update the resume for John Doe. Time - 02:22 Then I’ll move down, I’ll set up a file handle for this file sample_resume.pdf. I’ll set up an input stream on that file and then I’ll set that as the parameter for our binary stream for our prepared statement. Then I’ll move through and I’ll actually do an execute update. This will actually store this binary file from the file system into the actual database column. Time - 02:47 I just ran the application and here's the output of the program. So beginning it says that it’s reading the file and gives me the full path to the file just for sanity sake, I know which file is actually reading. Then it tells me that it's storing the resume in the database for our employee [email protected] and then it says that it completed successfully. Excellent. Time - 03:10 Now let's move over to MySQL tool and verify this. I'll take a look at the employees there in the database right now. l’ll run this query select * from employees and I'll get a list of the actual employees. Notice here for John Doe there’s an entry here for a resume, there's a BLOB entry. Note all the other entries are null. So we have a BLOB entry here. I can select this entry. I can right click. I can say, “Open Value in Editor” and it’s going to show me this BLOB. Again, it's a binary large object so we see all this binary data. Actually it should be displayed as hex. Time - 03:50 Instead of looking at it in this fashion there's a tab here called “Image.” I can select this tab and now it'll actually show me this image or the actual data as a PDF that I can view. This is the actual PDF document for this employee, John Doe. This looks really good. We know that we were successful in storing the BLOB in the actual database. Time - 04:18 Now that we know how to write BLOBs in the database let's learn how to read a BLOB from the database. In this example I'm going to read the employee’s resume from the database as a BLOB and then store it as a file on my local files system. Let's walk through the code. [snip] .... see the Transcripts tab for details.

Oracle SQL Tutorial 1 - Intro to Oracle Database
 
10:18
As illustrated in the video, Oracle Database is a program designed to hold lots of information, or data. There are all kinds of different databases and they all have their uses. Some of the most common ones are MySQL, SQL Server, Sybase, and MongoDB. All of these have different uses. The differences will be easier to understand after you learn more about each kind of database. We did not discuss it much in the video, but if you are wondering what “SQL” means in the title, it stands for structured query language. Structured query language is a human readable computer language that is used to tell databases to do things. We will discuss SQL and Oracle SQL Developer more in future videos. Databases are better than spreadsheets because they allow multiple users at one time, different levels of access given to users, recovery options and transactions, and it is more protected from hacking and malicious destruction. Programming languages often have very useful functions or methods that can be used to communicate to a database and therefore they are a naturally good option for the back end of programs. This course will go over all of the major parts of database programming using Oracle SQL. We will be using Oracle 11g, but these videos should still work with other versions, including the most recent 12c. Q and A ~~~~~~ How much does Oracle cost? The full enterprise edition costs thousands. They have other versions for less and they even have a FREE VERSION! This is known as the XE version (eXpress Edition). That is the one we will be using. How long does it take to learn SQL? You can learn all of the basics and be an efficient beginner database developer in only about a month of practice. To become an intermediate it can take anywhere from an additional 3 - 6 months with a only a few hours of studying and practicing each day. How can I learn SQL faster? Take notes and actually mess around with making your own database. Watch these videos until you understand the concepts within them, read articles and books that teach in more depth.

MySQL Tutorial for Beginners 12 - MySQL OR condition By Examples
 
11:55
In this post we will learn how to In this post we will learn How to Use MySQL OR Operator By Examples. So we will see how to use the MySQL OR condition with syntax and examples in MySQL.The SQL AND & OR operators are built into SQL-Where conditions to include or exclude certain query results. The use of operators follows Boolean algebra, which is familiar from mathematics lessons and easy to understand. SELECT column1, column1,...column_n table_name1, table_name2... [WHERE condition1 [AND [OR]] condition2.....; You can use asterisk (*) in place of columns. In that case, SELECT will return all the fields. The AND operator joins SQL conditions. The OR operator makes a distinction between two or more SQL conditions. OR operator always weighs more heavily in Boolean algebra than an AND operator . But first let's see What is MySQL . MySQL is a very popular, open source database. Officially pronounced “my Ess Que Ell” (not my sequel). Handles very large databases; very fast performance. Why are we using MySQL? Free (much cheaper than Oracle!) Each student can install MySQL locally. Easy to use Shell for creating tables, querying tables, etc.Easy to use with Java JDBC. While installing MySQL, it will prompt you to create a root password . At this stage please select a safe and secure password . Make sure you remember the password, to use it later.MySQL tutorial for beginners and professionals with examples on CRUD, insert statement, select statement, update statement, delete statement, use database, keys, joins etc. MySQL Database is world's most popular open source database because of its consistent fast performance, high reliability and ease of use. MySQL has Open Source License i.e. it has free GNU General Public License. SQL (Structured Query Language) is the language used to insert and retrieve content. Clients make queries on the database to Retrieve, Insert, Update or Delete content. #MySQL #MySQLTutorial #Ubuntu ----------------------Follow--------------------------------------------- My Website - http://www.codebind.com My Blog - https://goo.gl/Nd2pFn My Facebook Page - https://goo.gl/eLp2cQ Google+ - https://goo.gl/lvC5FX Twitter - https://twitter.com/ProgrammingKnow Pinterest - https://goo.gl/kCInUp Text Case Converter - https://goo.gl/pVpcwL ------------------Facebook Links ---------------------------------------- http://fb.me/ProgrammingKnowledgeLearning/ http://fb.me/AndroidTutorialsForBeginners http://fb.me/Programmingknowledge http://fb.me/CppProgrammingLanguage http://fb.me/JavaTutorialsAndCode http://fb.me/SQLiteTutorial http://fb.me/UbuntuLinuxTutorials http://fb.me/EasyOnlineConverter.

Creating a database, table, and inserting - SQLite3 with Python 3 part 1
 
10:59
Welcome to an SQLite mini-series! SQLite, as the name suggests, is a lite version of an SQL database. SQLite3 comes as a part of the Python 3 standard library. Databases offer, typically, a superior method of high-volume data input and output over a typical file such as a text file. SQLite is a "light" version that works based on SQL syntax. SQL is a programming language in itself, but is a very popular database language. Many websites use MySQL, for example. SQLite truly shines because it is extremely lightweight. Setting up an SQLite database is nearly instant, there is no server to set up, no users to define, and no permissions to concern yourself with. For this reason, it is often used as a developmental and protyping database, but it can and is used in production. The main issue with SQLite is that it winds up being much like any other flat-file, so high volume input/output, especially with simultaneous queries, can be problematic and slow. You may then ask, what really is the difference between a typical file and sqlite. First, SQLite will let you structure your data as a database, which can easily be queried, so you get that functionality both with adding new content and calling upon it later. Each table would likely need its own file if you were doing plain files, and SQLite is all in one. SQLite is also going to be buffering your data. A flat file will require a full load before you can start querying the full dataset, SQLite files don't work that way. Finally, edits do not require the entire file to be re-saved, it's just that part of the file. This improves performance significantly. Alright great, let's dive into some SQLite. https://pythonprogramming.net/sql-database-python-part-1-inserting-database/ Playlist: https://www.youtube.com/playlist?list=PLQVvvaa0QuDezJh0sC5CqXLKZTSKU1YNo https://pythonprogramming.net https://twitter.com/sentdex https://www.facebook.com/pythonprogramming.net/ https://plus.google.com/+sentdex

MySQL 32 - FLOAT and DOUBLE Data Types
 
06:23
FLOAT and DOUBLE data types are data types that can be used to store numbers that can include decimal numbers. They are specifically used to store estimates. What do I mean? I mean that the precision of a FLOAT or DOUBLE value can be lost when doing math. The data types are only capable of maintaining a certain level of precision. The level of precision is usually adequate for most mathematical operations. If you need to store exact data, you will want to look into using the INT or DECIMAL data type instead. The numbers stored in a FLOAT or DOUBLE column are called floating point numbers, we'll see why in just a moment. Why are they called floating point numbers? let's look at a number. 150. This number could be represented as 150, or it could be represented as 1.5 * 10^2, or 1.5e2. With floating point numbers, scientific notation is used. These numbers are called floating point numbers because the decimal can float to different spots as we change the exponent. This means that the data type needs to store the number, how many decimal the number needs moved, and a sign bit. The benefit of floating point numbers is that they allow us to store pretty huge numbers. The down side is that they are not storing values exactly because they are limited in size. This means that only a certain level of precision is to be expected from a floating point data type. If you remember from the video of DECIMAL, precision is the number of digits in a number. As long as the precision for one of these data types exceeds the need for your specific data, the data type can work fine. For example, if you are storing a number like 15 trillion, you don't have to worry as much with precision as your number does not contain a lot of digits. This number can be represented as 1.5 x 10^13. This is a lot different than trying to store 1.5534534534 x10^13. Now we know both of these data types do not maintain a high number of digits correctly, but what is the difference between FLOAT and DOUBLE. The difference is the amount of storage they take up. Float takes up 4 bytes while DOUBLE takes up 8. The benefit in DOUBLE is that because it has more room to store data, it has a higher level of precision and can store bigger numbers. Now, what level of precision can you expect from either of these? FLOAT around 7 and DOUBLE around 15. Now, these data types are obnoxious because the exact values depend on your operating system and in general these monsters cannot be trusted. Especially when you start doing math with different numbers. In general, it is recommended to use the DOUBLE data type to have a higher level of precision and calculations in MySQL are done with DOUBLE. Always remember… prepare for trouble, make it double. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Rank and Dense Rank in SQL Server
 
10:08
rank and dense_rank example difference between rank and dense_rank with example rank vs dense_rank in sql server 2008 sql server difference between rank and dense_rank In this video we will discuss Rank and Dense_Rank functions in SQL Server Rank and Dense_Rank functions Introduced in SQL Server 2005 Returns a rank starting at 1 based on the ordering of rows imposed by the ORDER BY clause ORDER BY clause is required PARTITION BY clause is optional When the data is partitioned, rank is reset to 1 when the partition changes Difference between Rank and Dense_Rank functions Rank function skips ranking(s) if there is a tie where as Dense_Rank will not. For example : If you have 2 rows at rank 1 and you have 5 rows in total. RANK() returns - 1, 1, 3, 4, 5 DENSE_RANK returns - 1, 1, 2, 3, 4 Syntax : RANK() OVER (ORDER BY Col1, Col2, ...) DENSE_RANK() OVER (ORDER BY Col1, Col2, ...) RANK() and DENSE_RANK() functions without PARTITION BY clause : In this example, data is not partitioned, so RANK() function provides a consecutive numbering except when there is a tie. Rank 2 is skipped as there are 2 rows at rank 1. The third row gets rank 3. DENSE_RANK() on the other hand will not skip ranks if there is a tie. The first 2 rows get rank 1. Third row gets rank 2. SELECT Name, Salary, Gender, RANK() OVER (ORDER BY Salary DESC) AS [Rank], DENSE_RANK() OVER (ORDER BY Salary DESC) AS DenseRank FROM Employees RANK() and DENSE_RANK() functions with PARTITION BY clause : Notice when the partition changes from Female to Male Rank is reset to 1 SELECT Name, Salary, Gender, RANK() OVER (PARTITION BY Gender ORDER BY Salary DESC) AS [Rank], DENSE_RANK() OVER (PARTITION BY Gender ORDER BY Salary DESC) AS DenseRank FROM Employees Use case for RANK and DENSE_RANK functions : Both these functions can be used to find Nth highest salary. However, which function to use depends on what you want to do when there is a tie. Let me explain with an example. If there are 2 employees with the FIRST highest salary, there are 2 different business cases 1. If your business case is, not to produce any result for the SECOND highest salary, then use RANK function 2. If your business case is to return the next Salary after the tied rows as the SECOND highest Salary, then use DENSE_RANK function Since we have 2 Employees with the FIRST highest salary. Rank() function will not return any rows for the SECOND highest Salary. WITH Result AS ( SELECT Salary, RANK() OVER (ORDER BY Salary DESC) AS Salary_Rank FROM Employees ) SELECT TOP 1 Salary FROM Result WHERE Salary_Rank = 2 Though we have 2 Employees with the FIRST highest salary. Dense_Rank() function returns, the next Salary after the tied rows as the SECOND highest Salary WITH Result AS ( SELECT Salary, DENSE_RANK() OVER (ORDER BY Salary DESC) AS Salary_Rank FROM Employees ) SELECT TOP 1 Salary FROM Result WHERE Salary_Rank = 2 You can also use RANK and DENSE_RANK functions to find the Nth highest Salary among Male or Female employee groups. The following query finds the 3rd highest salary amount paid among the Female employees group WITH Result AS ( SELECT Salary, Gender, DENSE_RANK() OVER (PARTITION BY Gender ORDER BY Salary DESC) AS Salary_Rank FROM Employees ) SELECT TOP 1 Salary FROM Result WHERE Salary_Rank = 3 AND Gender = 'Female' Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/rank-and-denserank-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/rank-and-denserank-in-sql-server_1.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
