07:23
Difference between NVL,NVL2, NULLIF and COALESCE NVL function will check whether the first input parameter is null, if first input parameter is null then the function returns the second parameter value as output. NVL2 function will check the first parameter, and return second parameter if the first parameter is not null, otherwise returns third parameter. NULLIF will compare the input parameters ( first and second parameter ), and returns NULL of both are same, otherwise returns the first parameter value. COALESCE, returns the first not null expression in the given input parameters. -------------------------------------------------------------------------------------------------------- List of all the SQL and PLSQL interview questions https://easy-learning-tech.blogspot.com/p/oracle-sql-plsql-interview-questions.html

Java JDBC Tutorial – Part 8: JDBC Database MetaData with MySQL
 
05:24
NEED TO LEARN JAVA? - 5 FREE JAVA VIDEO COURSES - CLICK HERE - https://goo.gl/7i95F8 --- View more videos on my "Java JDBC Tutorial" Playlist: http://goo.gl/crT4nS Download Java Source Code: http://www.luv2code.com/?p=1039, Follow Me on Twitter: https://twitter.com/darbyluvs2code Please SUBSCRIBE to this channel: https://www.youtube.com/user/luv2codetv?sub_confirmation=1 --- In this video tutorial we will learn how to retrieve JDBC database metadata with MySQL. --- Transcript Time - 00:00 Hi, this is Chad (Shod) with luv2code.com. Welcome back to another tutorial on Java JDBC. In this video we will learn how to use Database Metadata. For this tutorial we'll use the following table: employees. The table also has sample data for testing. I have a SQL script that'll create the table and add sample data for you. You can download it from the link below. Time - 00:30 Database Metadata can give you information about your database. To get started with Database Metadata, you must first retrieve it from the connection object. This is accomplished by calling myCon.getMetadata, then we can call some methods on the object such as get product name and version, get JDBC driver information and so on. Time - 00:48 There are a lot of methods available, you can go online and you can Google JDBC Metadata, there you'll find the actual JavaDoc for this class and you'll see all the methods that are available for it. Time - 01:00 Let's switch over to Eclipse and see this in action. I have a very simple program called Metadata Basic Info. Let's walk through the code. The first thing we'll do in this application is we will get a connection to the database. Then using this database connection I can get the Metadata, it returns a special Database Metadata object. Now with this object I can retrieve information about the database, I can get the actual database product name, I could also get the product version and then from there I can move forward and get information about the JDBC driver. I can get the driver's name and also the driver version. Time - 01:49 Let's go ahead and run this application. Once we run it, we see the output. It shows us the product name and the actual version, the actual JDBC driver name, MySQL Connector and also the JDBC driver version that we're using. This is very good information that we retrieved by accessing the Database Metadata. Time - 02:13 We can also get information about the database schema. For example, we can get a list of all tables and also get a list of column names for each table along with our types. Time - 02:29 All right so let's switch over to Eclipse and is this in action. I have a very simple program called Schema Info and let's walk through the code. In this main method I have some variables set up for catalog and all the various patterns. When you make calls to some of these Database Metadata methods, you can actually pass in patterns but for right now just keep it null just to keep it simple. Let's step through the code, the first thing we do is we get a connection to a database and we get the Metadata, we've seen all this before, then I like to get a list of tables so I say, "Database Metadata get tables" and I pass in those various patterns. Time - 03:05 This will give me a list of all of the tables for this demo schema, it's going to return it as a ResultSet. This works like a normal ResultSet, I can just loop through this ResultSet and I can retrieve each table name and print it out. This will give me a list of all tables for this given schema. Time - 03:24 I'd like to do a similar thing for columns. I'd like to get a list of all the columns for a given table. In this example, I want to get all of the columns for the employees table so I pass in employees here and I pass in any other patterns and so on and they're all set to null but here I want to get the employees table. It's going to return a list of columns for this employees table as a ResultSet and just like before I can just walk through this ResultSet and I can print out each column name. They also have methods for getting column types and so on but this is enough to get us started for now. Time - 04:02 Now we can see the output of the application. The first thing at the top we get a list of tables and so in this example we only have one table and that's employees. Then we can also get a list of columns for this employees table and we have these six columns here: ID, last name, first name, email, department and salary.

Oracle Database11g tutorials 13 || SQL substr function / SQL substring function
 
06:34
link of SQL substr blog : http://www.rebellionrider.com/SQL-substr-function.htm SQL substr function SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. 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

Oracle LENGTH Function
 
01:23
https://www.databasestar.com/oracle-length/ The Oracle LENGTH function allows you to find the length of a string, also known as the number of characters in a string. It’s a common feature in different languages, and SQL is no different. The LENGTH function only has one parameter: LENGTH ( string_value ) The parameter is the string_value which is the value to check the length of. The function returns a number that represents the number of characters in the function. Some points to remember about the Oracle LENGTH function: If string_value is NULL, then LENGTH will return NULL. If string_value is an empty string, the LENGTH will return NULL. The string_value can be any of the character data types - CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, NCLOB. If the string_value is a CHAR data type, then the LENGTH will include any trailing spaces in the value. For more information about the Oracle LENGTH function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-length/

SQL: Extract function
 
03:38
In this tutorial, you'll learn how to make use of extract function. PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

Every collection contains a named list of data elements (or members) which can have up to 50 character attributes (VARCHAR2(4000)), five number attributes, five date attributes, one XML Type attribute, one large binary attribute (BLOB), and one large character attribute (CLOB). You insert, update, and delete collection information using the PL/SQL API APEX_COLLECTION. The following are examples of when you might use collections: When you are creating a data-entry wizard in which multiple rows of information first need to be collected within a logical transaction. You can use collections to temporarily store the contents of the multiple rows of information, before performing the final step in the wizard when both the physical and logical transactions are completed. When your application includes an update page on which a user updates multiple detail rows on one page. The user can make many updates, apply these updates to a collection and then call a final process to apply the changes to the database. When you are building a wizard where you are collecting an arbitrary number of attributes. At the end of the wizard, the user then performs a task that takes the information temporarily stored in the collection and applies it to the database. Beginning in Oracle Database 12c, database columns of data type VARCHAR2 can be defined up to 32,767 bytes. This requires that the database initialization parameter MAX_STRING_SIZE has a value of EXTENDED. If Application Express was installed in Oracle Database 12c and with MAX_STRING_SIZE = EXTENDED, then the tables for the Application Express collections will be defined to support up 32,767 bytes for the character attributes of a collection. For the methods in the APEX_COLLECTION API, all references to character attributes (c001 through c050) can support up to 32,767 bytes.

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

NEED TO LEARN JAVA? - 5 FREE JAVA VIDEO COURSES - CLICK HERE - https://goo.gl/7i95F8 --- View more videos on my "Java JDBC Tutorial" Playlist: http://goo.gl/crT4nS Download Java Source Code: http://www.luv2code.com/?p=1057 Follow Me on Twitter: https://twitter.com/luv2codetv Please SUBSCRIBE to this channel: https://www.youtube.com/user/luv2codetv?sub_confirmation=1 --- In this video tutorial we will learn how to use JDBC to read and write BLOB with MySQL. --- Transcript Time - 00:00 Hi, this is Chad (Shod) with luv2code.com. 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.

Oracle UPPER Function
 
02:32
https://www.databasestar.com/oracle-upper-lower/ The Oracle UPPER function is used to convert a string to an uppercase value. It capitalises a string value. It’s useful for comparing text or string values that may have mixed case, such as user input or data from different tables. The opposite of the UPPER function is the LOWER function (which converts to lower case). The syntax of UPPER is: UPPER(input_string) The input_string is the string value to convert to an upper case value. It can be any of CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB. The return type is the same as the input type. You can use the UPPER function in a WHERE clause. However, unless you have a function-based index on the column, any indexes won’t be used. For example, if you have an index on first_name, a query that uses “WHERE UPPER(first_name)” won’t use this index. You’ll have to create an index on the UPPER(first_name) for this to be used. It’s not required, but it’s just something to keep in mind. For more information about the Oracle UPPER function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-upper-lower/

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!)

CONCAT Function in SQL Query with Example
 
04:26
CONCAT(): Syntax: CONCAT(char1,char2); CONCAT returns char1 concatenated with char2. Both char1 and char2 can be any of the datatypes CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB. The string returned is in the same character set as char1. Its datatype depends on the datatypes of the arguments. In concatenations of two different datatypes, Oracle Database returns the datatype that results in a lossless conversion. Therefore, if one of the arguments is a LOB, then the returned value is a LOB. If one of the arguments is a national datatype, then the returned value is a national datatype. For example: CONCAT(CLOB, NCLOB) returns NCLOB CONCAT(NCLOB, NCHAR) returns NCLOB CONCAT(NCLOB, CHAR) returns NCLOB CONCAT(NCHAR, CLOB) returns NCLOB This function is equivalent to the concatenation operator (||). We can achieve the same using operator '||'. Below two statements are equal: select concat(concat(ename,'''salary is:'),sal) from emp; select ename||'''salary is:'||sal from emp;
