Session6 Data type in Oracle
 
15:25
Session 6: Datatypes In Oracle   ALPHABET           : A-Z , a-z NUMBER              : 0-9 (with precision and scale) DATE / Temporal  : any Date and time (Hours, Minutes, Seconds, Mili-seconds, Timestamp, Timezone etc)   Alphabet + Number = Alphanumeric Data                                     = String / CHARACTER Datatype Category Number                    =  Numeric Datatype Category Date                         = Date Datatype Category 1. CHARACTER Datatype: CHAR, VARCHAR, NCHAR: CHAR is fixed length datatype and VARCHAR is Variable length datatype to store character data. i.e. A-Z , a-z , 0-9 , all keyboard characters etc. The default size is 1 character and it can store maximum up to 2000 bytes. Example : EName, EmpID, PassportNo, SSN, etc. EName CHAR(10) := ‘TOM’; wastage of 7 space after the string EName VARCHAR(10) := ‘TOM’; Spaces can be Reuse which left after the string NCHAR additionally handles NLS(National Language Support). Oracle supports a reliable Unicode datatype through NCHAR , NVARCHAR2 , and NCLOB  VARCHAR2, NVARCHAR2: These are Variable length datatype. VARCHAR2 handles alphanumeric character string whereas NVARCHAR2 handles alphanumeric character string with NLS(National Language Support). The default size is 1 character and it can store maximum up to 4000 bytes.   LONG:  Variable length string.  (Maximum size: 2 GB - 1) Only one LONG column is allowed per table. RAW:    Variable length binary string (Maximum size 2000 bytes) LONG RAW: Variable length binary string (Maximum size 2GB) 2. NUMERIC Datatype: NUMBER: It stores Numeric values and performs numeric calculations. NUMBER,   NUMBER(n),   NUMBER(p,s) It stores Numbers up to 38 digits of precision. SeqNo NUMBER;                     1, 123, 12345678 EmpID NUMBER(4);                 1, 123, 1234 Sal NUMBER(7,2);                     23456.78 , 123.45 — correction in video: Sal NUMBER(a7,2); which is wrong please ignore. 1234567 can be a type of NUMBER, NUMBER(7), NUMBER(7,0) It can store both integer and floating point numbers NUMERIC(p,s) FLOAT:   Ex:  EmpSal FLOAT;    FLOAT(7)       Decimal Points allowed DEC(p,s), DECIMAL(p,s) , REAL, DOUBLE PRECISION INTEGER:   Ex:  SSN INTEGER;       Decimal Points are not allowed INT, SMALLINT 3. DATE Datatype: DATE: It stores DATE(Date, Month, Year) and Time(Hour, Minute, Second, AM/PM) and performs calculations with such data. Default DATE format in Oracle is “DD-MON-YY” Based on "Gregorian calendar" where the date ranges from “JAN 1 4712 BC” to “DEC 31 9999 AD” doj DATE;    “18-MAR-2010 12:30:00 PM” TIMESTAMP:    It can store all parameters as DATE datatype and additionally it can have “Fraction of seconds” and TIMESTAMP WITH TIMEZONE / TIMESTAMP WITHOUT TIMEZONE. Range from 0-9 digits, the default size is 6. 4. LOB Datatype: LOB: “Large Object” data. It can store pictures, motion pictures, Textfiles etc. CLOB: “Character Large Object” is used to store structured information like a text file with a specific file format. BLOB: “Binary Large Object” is used to store Un-structured information like Image, JPEG files, MPEG files etc. BFILE: “Binary File” is used to store the pointer to a specific file / Just store the location of a file. Maximum size: (4 GB - 1) * DB_BLOCK_SIZE initialization parameter (8 TB to 128 TB) Extra Information: NCLOB : It supports all the character set supported by CLOB and additionally it handles NLS(National Language Support ) Maximum size: (4 GB - 1) * DB_BLOCK_SIZE initialization parameter (8 TB to 128 TB) ROWID and UROWID(optional size) Datatype: contains fixed length Binary data.

Oracle SQL Tutorial 33 - NUMBER Data Type
 
07:18
This video we are going to discuss the NUMBER data type. The Number data type is used to store integers, and real numbers. When you create a column as a NUMBER, you can store pretty huge or pretty small numbers in this column. Now there are two things you need to consider when working with numbers, and that is the precision as well as the how big the number is. For example, we can store the number 9.9. This has two significant digits. We could also store the number 9.9 X 10^4. In this situation, the number is much larger, but the number of significant digits is the same. 9.9 are the significant digits. When we expand this out we just have 99000, and the zeros are just used for size and are not considered "significant" in this situation. In fact, you get a max precision of 38, but a maximum value of 9.99 * 10^125. You can also use this data type to store very small numbers. Check the docs for the specifics on maximums and minimums. You can provide it with two pieces of information: Precision - The total number of digits. Scale - The number of digits to the right of the decimal. You do it in this format: NUMBER (precision, scale). The important thing to remember in this is that when you specify a precision, you will be limiting the max size of the numbers. The secret behind this data type is that it is actually stored in scientific notation. That is we store a number and then we can multiply it by 10 raised to some power. This allows us to store much larger numbers without taking up a ton of space. The oracle docs actually gives a formula that you can use to see how much storage is going to be required for a specific NUMBER data type. How much precision can be used? The acceptable range is 1-38. What about scale? The range is actually -84 to 127. I'll explain the scale in more detail in an upcoming video. That's because there is a lot of confusing things here…What does it mean for the scale to be negative? How can we have a scale that is bigger that the total number of digits available through the precision. That's a topic for another video. It's important to understand that when we increase our scale, we decrease the max size of the number. For example if we have a precision of 5 and a scale of 3, the highest number we can store is 99.999. This is in contrast to a precision of 5 and a scale of 2 which allows for up to 99.999. Either way you get 5 significant digits, but the numbers of digits to the left and right of the decimal change. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

View & manage your progress/pace 3. In-class projects and code reviews 4. Personal guidance from your Mentors ---------------------------------------------------------------------------------------- A variable is nothing but a name given to a storage area that our programs can manipulate. Each variable in PL/SQL has a specific data type, which determines the size and layout of the variable's memory; the range of values that can be stored within that memory and the set of operations that can be applied to the variable. The name of a PL/SQL variable consists of a letter optionally followed by more letters, numerals, dollar signs, underscores, and number signs and should not exceed 30 characters. By default, variable names are not case-sensitive. You cannot use a reserved PL/SQL keyword as a variable name. PL/SQL programming language allows to define various types of variables, which we will cover in subsequent chapters like date time data types, records, collections, etc. For this chapter, let us study only basic variable types. With PL/SQL you can declare variables and then use them in SQL and procedural statements anywhere that an expression can be used. Variables can be used for the following: • Temporary storage of data: Data can be temporarily stored in one or more variables for use when validating data input and for processing later in the data flow process. • Manipulation of stored values: Variables can be used for calculations and other data manipulations without accessing the database. • Reusability: After they are declared, variables can be used repeatedly in an application simply by referencing them in other statements, including other declarative statements. • Ease of maintenance: When using %TYPE and %ROWTYPE (more information on %ROWTYPE is covered in a subsequent lesson), you declare variables, basing the declarations on the definitions of database columns. If an underlying definition changes, the variable declaration changes accordingly at run time. This provides data independence, reduces maintenance costs, and allows programs to adapt as the database changes to meet new business needs. More information on %TYPE is covered later in this lesson. Types of Variables" All PL/SQL variables have a data type, which specifies a storage format, constraints, and valid range of values. PL/SQL supports four data type categories—scalar, composite, reference, and LOB (large object)—that you can use for declaring variables, constants, and pointers. • Scalar data types hold a single value. The main data types are those that correspond to column types in Oracle server tables; PL/SQL also supports Boolean variables. • Composite data types, such as records, allow groups of fields to be defined and manipulated in PL/SQL blocks. • Reference data types hold values, called pointers, that designate other program items. Reference data types are not covered in this course. • LOB data types hold values, called locators, that specify the location of large objects (such as graphic images) that are stored out of line. LOB data types are discussed in detail later in this course.

Oracle SQL Tutorial 32 - VARCHAR2 and NVARCHAR2
 
03:06
This video we are going to discuss the VARCHAR2 and the NVARCHAR2 data types. The previous videos are a good foundation to this video. I've actually discussed so much stuff in those videos that I don’t have a whole lot to say. Good for you, right? I discussed over the previous videos that you should prefer to use VARCHAR2 over CHAR. That's because there is not a difference in performance or storage for a VARCHAR2 column. The only difference is that an CHAR column forces each value to take up a certain length even if it's not. There is one difference between the variable length and fixed length data types here that you need to know about, and that is storage limits. CHAR has a limit of 2000 bytes, while VARCHAR2 has a limit of 4000 bytes. That means you can store twice as much junk in a VARCHAR2 column! Other than that, these data types work exactly the same. I recommend you always use the VARCHAR2 data types instead of the CHAR data types, and only use NVARCHAR2 if you have a non-Unicode database. This will allow you to store Unicode characters in a column. Now, the amount of storage you can put in a VARCHAR2 column is twice what you can put in a CHAR column, but 4000 characters is still not very many characters. This is where the LOB data types come in, which we will discuss in the next video! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

Oracle SQL Tutorial 23 - Intro to Data Types
 
05:03
Every column within a table has to be given what is known as a datatype. A data type is a fairly simple concept when you dissect the word. It is literally the type of data. Why do we use types, though? The biggest benefit is so that Oracle knows how to interpret and work with our data. It also makes the database better at rejecting incorrect data. If we had to concept of a data type, there would be a lot more work involved in forcing data to be of the right format. It would also be harder for us to get the database to treat the data in the correct way. In addition to this, a database can optimize storage and performance for a column if everything is of the same data type. Because of this, each column can only support one data type. There are numerous different data types in Oracle and it helps us if we categorize them. The first types of datatypes we should learn about are: String, Numeric, Temporal Now, there are few more categories we could make, but these are the main ones. We will worry about the other ones another day as I am only introducing the topic. A string data type is anything within quotes. Most databases use single quotes for string data. Inside of the quotes can be any number of characters. What is a character? Think of any letter, number, or symbol you can type. Some people call these letters, numbers, and symbols alphanumeric. Numeric data type includes only numbers. These data types are often used for data that you plan on using for mathematical calculations. Temporal data types are data types that are used for dates and times. Now, each data type is probably going to have some options you'll need to worry about, but one that comes up with every data type is storage. The reason we need to consider storage is because we may end up with millions of rows in a table and the difference between a few bytes for each row will make a huge difference when we look at the whole picture. When a data type gives you the option of size, you will want to a size that will be able to hold what you need, but nothing more. In the upcoming videos we are going to discuss the available data types in more detail. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

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 24 - Important Data Types
 
06:09
In the upcoming videos we are going to discuss data types in depth, but I don't want to drown you in all of the details. Because of that, I'm giving you this video which is going to introduce you to the most important data types. Then, in the upcoming videos, I'll describe them in more depth. One of the data types we've already discussed in this video is NUMBER. This data type is used to, obviously, store a number. It can be used to store integers (whole numbers), or numbers with decimals. There are two other numeric data types you should know of. BINARY_FLOAT and BINARY_DOUBLE are both numeric data types that are known as floating point numbers. A floating point number is often used for large numbers that have decimal places where it is acceptable to not be completely precise. What I mean by this is that these numbers can only store numbers correctly up to a certain decimal point. If you need perfect precision, you will want to use the NUMBER data type. Now storing numbers is good sometimes, but occasionally you will want to store string data. String data can be any sequence of characters, including numbers. By telling the database that a column is a string data type, the database knows how to treat that column. There are four important string data types that you need to know about. The first two are CHAR and NCHAR. These data types are used to store a fixed-length string. So for example, you can say you want to store 12 characters. This means that every value for this column will be exactly 12 characters. If you insert less than 12 characters, the data will be padded with spaces. This means you will want to use one of these data types when every value in the column is the same length. What is the difference between CHAR and NCHAR? CHAR uses what is known as ASCII while NCHAR uses Unicode. The difference is what characters are allowed and how much space each character takes. ASCII takes up less space but only supports English, numbers, and some symbols. UNICODE allows you to store characters from multiple languages but takes up more space. Those were both fixed-length string. What if you want to store data that changes in length? That is where VARCHAR2 and NVARCHAR2 come in. When it comes to storing dates, the data types that are most important are DATE and TIMESTAMP. Date can be used to store dates and time. Timestamp is a data type that can be used to store an exact moment in time. Lastly, there are interval types. These store a date range. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

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!)

Lesson - 15 : JDBC -  How to insert and select image from Database
 
09:34
Inserting a picture is nothing but storing binary data(bytes) of the picture into a database table.In JDBC we need preparestatement interface for transferring binary data from java program to database.If we want to insert a picture into a table then that table column should be of blob(binary large object) type.The following are the steps required for inserting a picture 1. Creating a java.io.File object for the picture. 2. Create java.io.FileInputStream object for reading the binary data from the file. 3. Find size of the picture file. 4. Call setBinaryStream() for inserting binarydata of the picture into an SQL statement.

Lesson - 68 : Hibernate - Insert & Reading image using XML and Annotation Config
 
21:04
Hibernate – Insert and Reading Image Using Hibernate: ->An image can not be inserted or retrieved directly using hibernate. To do inserting or reading an image operation that image must be transfer to hibernate in the form of or as a part of pojo class object. ->To set an image to a pojo class object. Pojo class should contain a property of type BLOB(java.sql.Blob). ->To set an image to a pojo class object first we need to read binary data of that image then we need to create a java.sql.Blob object and then we need to set java.sql.Blob object to pojo class object. ->To store binary data of an image in database the clumn of a table should be of blob type(BLOB-BinaryLargeOBject). To convert an image file into a java.sql.Blob object, we need to follow the below steps. 1. Create a File object (java.io.File object) for an image file. 2. Find size of the image file. 3. Create a byte[] with the size of the image. 4. Create a java.io.FileInputStream object for an image file. 5. Read the binary data of image file and store it in a byte[]. 6. Create a Blob for byte[]. 7. Finally set blob object to pojo class object. Sample Code : File file = new File("E:\\Desktop items\\Images\\App-1Hierarchy.png"); int length = (int)file.length(); byte b[] = new byte[length]; FileInputStream fis = new FileInputStream(file); fis.read(b); Blob photo = Hibernate.createBlob(b); The following are the steps to required to read an image 1. Read a pojo class object from a database using hibernate. 2. Read java.sql.Blob object from pojo object. 3. Read binary data from Blob object. 4. create a FileOutputStream object for writing or creating a new image file. 5. Read binary data from InputStreamObject and write it into new image file. Sample Code : InputStream in = blb.getBinaryStream(); FileOutputStream fos= new FileOutputStream("E:\\Desktop items\\Images\\App-1Hierarchy.png"); int k; while((k=in.read())!=-1){ fos.write(k); } fos.close(); Hibernate Examples Project Github Link : https://github.com/SadaLearningHub1/Hibernate-Projects

Very Large Databases Lessons Learned
 
01:10:26
Whoever coined the term "one size fits all" was not a DBA. Very large databases (VLDBs) have different needs from their smaller counterparts, and the techniques for effectively managing them need to grow along with their contents. In this session, join Microsoft Certified Master Bob Pusateri as he shares lessons learned over years of maintaining databases over 20TB in size. This talk will include techniques for speeding up maintenance operations before they start running unacceptably long, methods for minimizing user impact while critical processes run, the awesome world of data compression, and new features in SQL Server 2014 and 2016 that can really make your life easier. You'll also see how generally-accepted best practices aren't always the best idea for VLDB environments, and how, when, and why deviating from them can be appropriate. Just because databases are huge doesn't mean they aren't manageable, attend this session and see for yourself!
