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!)

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 EMPTY_BLOB Function
 
01:58
https://www.databasestar.com/oracle-lob-functions/ The Oracle EMPTY_BLOB function is used to initialise a LOB column to an empty value. You can use it in an INSERT statement, an UPDATE statement, or with a variable in PL/SQL. The syntax of the EMPTY_BLOB function is: EMPTY_BLOB That’s it - no parameters. Why would you set a BLOB value to empty? It means you have initialised it but not given it a value. It’s good to know this function exists if you ever need to use it. For more information about the Oracle EMPTY_BLOB function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-lob-functions/

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.

Tool used in this tutorial is command prompt. This tutorial series is part of SQL expert exam certification training. if you are preparing for SQL certification you can use my tutorials.

Let's see the Syntax Substr (source_string, start_pos, Substr_length) As we can see SQL substr function takes 3 parameters. First one is Source string from which you want to extract the segment. Second parameter is Starting position for sub string from the Source string. And the third parameter is Substr_length which is the length for the substring. First two parameters are mandatory to specify while third one is optional. So we can say. SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. First parameter source string can be of any data type CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB whereas both start_pos, Substr_length parameters must be number data type. The returning result of SQL Substr function is of same data type of source string. Let's see an example of SQL Substr function. SELECT substr('www.RebellionRider.com',5,14) FROM dual; Here in this query url of my website www.RebellionRider.com is our source string with the total length of 22 characters, Now, I want to extract the name of my website that is, RebellionRider. So if you count the total length of the name of the website, it is 14. That's why I have specified 14 as my third parameter of SQL Substr function which is substr_length. Also the name of the website RebellionRider is starting from 5th position therefore I have specified 5 at second parameter of SQL substr function which is strt_pos or starting position. Execute it. Here is our result RebellionRider When starting position is larger than the length of source string. In this case SQL Substr function will return NULL as a result. Let's do an example. SELECT substr('www.RebellionRider.com',23,14) FROM dual; As you can see here I have specified 23 at starting position and the total length of our source string is 22 characters Let's execute And the result is Null. Second scenario When the Substr_length is greater than source string In this case the segment return is the substring from starting position to the end of the string. For example SELECT substr('www.RebellionRider.com',5,23) FROM dual; Our starting position is at 5 means at the first R of RebellionRider and length of substring is set to 23 which is greater than the length of source string that is 22. Execute. As you can see we get a substring from first R of RebellionRider till the end of the source String. Third scenario When you supply numeric or arithmetic expression or a DATE instead of character as Source string to SQL Substr function In this scenario If you have supplied a numeric string instead of character as source string, the oracle engine casts them as a character when they occur as parameter to SQL Substr function. And if you have supplied Arithmetic expression or a DATE then The Oracle engine first solves or evaluates the Arithmetic expression or the DATE Then casts them as a character. Means if you have arithmetic expression in your source string then oracle will first solve it and then change or say cast the value of its result into character. Let's see some example. SELECT substr(50000-7,2,4) FROM dual; Oracle first evaluates the arithmetic expression that is 50000-7 equals to 49993. And then oracle engine casts this result 49993 into a character string. Means 49993 will be a 5 characters string. Starting position of substring is 2, that means from the first 9 of 49993 We specified the length of substring is 4 so we must get 9993 as our result. Let's check execute

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.

What is CHARACTER LARGE OBJECT? What does CHARACTER LARGE OBJECT mean? CHARACTER LARGE OBJECT meaning - CHARACTER LARGE OBJECT definition - CHARACTER LARGE OBJECT explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ A Character Large OBject (or CLOB) is a collection of character data in a database management system, usually stored in a separate location that is referenced in the table itself. Oracle and IBM DB2 provide a construct explicitly named CLOB, and the majority of other database systems support some form of the concept, often labeled as text, memo or long character fields. CLOBs usually have very high size-limits, of the order of 2 GB. The tradeoff for the capacity is usually limited access methods. In particular, some database systems limit certain SQL clauses and/or functions, such as LIKE or SUBSTRING from being used on CLOBs. Those that permit such operations may perform them very slowly. Alternative methods of accessing the data are often provided, including means of extracting or inserting ranges of data from the CLOB. Database systems vary in their storage patterns for CLOBs. Some systems always store CLOBs as a reference to out-of-table data, while others store small CLOBs in-table, changing their storage patterns when the size of the data grows beyond a threshold. Other systems are configurable in their behavior.
