Oracle ADD_MONTHS Function
https://www.databasestar.com/oracle-add_months/ The Oracle ADD_MONTHS allows you to add a specified number of months to a date value, and return the new date value. It’s great for performing calculations on dates, or date arithmetic, which can be hard in many different programming languages. The syntax of the ADD_MONTHS function is: ADD_MONTHS ( input_date, number_months ) The function returns a DATE value. The parameters of this function are: - input_date (mandatory): This is the starting date, or the date that you will add a number of months to. - number_months (mandatory): This is an integer value that represents the number of months to add to input_date. The input_date can be any datetime value, or even a character value that can be converted to a date. Also, the number_months can be any number value, or a character value that can be converted to a number. What if the number of days in the two months are different? For example, adding a month to Jan 31 could result in Feb 31, which does not exist. Well, in this case, Oracle would work out that the date does not exist, and use the last date of the month (e.g. Feb 28). You can also provide a negative value for ADD_MONTHS to subtract months from the specified date. For more information about the Oracle ADD_MONTHS function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-add_months/

Oracle MONTHS_BETWEEN Function
https://www.databasestar.com/oracle-months_between/ The Oracle MONTHS_BETWEEN function allows you to find the number of months between two dates. You can enter two dates and the function returns the difference. This function is often used as part of other calculations. Sometimes you’ll want to know the difference between two dates to perform other functions. The syntax of the MONTHS_BETWEEN function is: MONTHS_BETWEEN(date1, date2) What do these two parameters mean? The function performs date1 minus date2. So, if date1 is larger, the result is positive. If date2 is larger, then the result is negative. What data type is returned? It depends on the values you provide. If the dates are both on the same day of the month (e.g. both on the 10th of the month), then the result is an integer or whole number. If not, then the result will be a decimal value. For more information on the MONTHS_BETWEEN function, including the code used in this video and examples, read the related article here: https://www.databasestar.com/oracle-months_between/

SQL: Extract function
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.

ADD_MONTHS Function in SQL Query with Example
ADD_MONTHS(): The Oracle/PLSQL ADD_MONTHS function returns a date plus n months. Syntax: ADD_MONTHS( date1, n ) Arguments: date1 is the starting date (before the n months have been added). n is the number of months to add to date1. Example: Let's look at some Oracle ADD_MONTHS function examples and explore how you would use the ADD_MONTHS function in Oracle/PLSQL. ADD_MONTHS('01-Aug-03', 3) would return '01-Nov-03' ADD_MONTHS('01-Aug-03', -3) would return '01-May-03' ADD_MONTHS('21-Aug-03', -3) would return '21-May-03' ADD_MONTHS('31-Jan-03', 1) would return '28-Feb-03' Thanks for watching..:)

Oracle TO_TIMESTAMP_TZ Function
https://www.databasestar.com/oracle-timezone-functions/ The Oracle TO_TIMESTAMP_TZ function can be confusing, but we’ll explain it in this video. This function allows you to convert a string value into a TIMESTAMP WITH TIME ZONE value. A TIMESTAMP WITH TIME ZONE value is a type of DATE, but has a few components: - A date, including day, month, and year - A time, including hours, minutes, and seconds - A time zone, which is the number of hours and minutes difference from GMT This is a useful data type because it allows you to store dates in different time zones, and allow users in other time zones to see the data in a way that makes sense to them. The time zone part is the difference from GMT. This means that a “+7:00” is 7 hours ahead of GMT (e.g. Bangkok) and “-5:00” is 5 hours behind GMT (e.g. US Eastern Standard Time). The syntax of the TO_TIMESTAMP_TZ function is: TO_TIMESTAMP_TZ ( input_string [, format_mask] [, nls_param] ) The input_string parameter is the string you want to convert. The format_mask is where you specify the format of the input_string parameter. This is so you can specify the input_string in a variety of formats, and just use this format_mask to indicate which format it is in. The nls_param parameter is another optional parameter, and allows you to specify the returning language of the month and day names.

Oracle TO_TIMESTAMP Function
https://www.databasestar.com/oracle-to_timestamp/ The Oracle TO_TIMESTAMP function can be confusing, but we’ll explain it in this video. This function allows you to convert a string value into a TIMESTAMP value. A TIMESTAMP value is a type of DATE, but has a few components: - A date, including day, month, and year - A time, including hours, minutes, seconds, and fractional seconds This is a useful data type because it allows you to store a time down to fractions of a second. The syntax of the TO_TIMESTAMP function is: TO_TIMESTAMP ( input_string [, format_mask] [, nls_param] ) The input_string parameter is the string you want to convert. The format_mask is where you specify the format of the input_string parameter. This is so you can specify the input_string in a variety of formats, and just use this format_mask to indicate which format it is in. The nls_param parameter is another optional parameter, and allows you to specify the returning language of the month and day names. The default format will depend on the region you’re running your database in. In my example (using Oracle Express in Australia), the default format is ‘DD-MM-RRRR HH:MI:SS AM’.

Oracle FROM_TZ Function
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/

Oracle LPAD Function
https://www.databasestar.com/oracle-lpad/ The Oracle LPAD function is used to add extra characters to the left of a text value. This is called “padding”, and the function is called LPAD because the L stands for “left” and it “left pads” a text value. It’s the opposite of RPAD, which pads characters to the right of the value. The LPAD function can be useful for ensuring all values are the same length, or if there is another requirement you have for adding characters to the end. The syntax is: LPAD(expr, length [,pad_expression]) The expr parameter is the text value you want to pad or add characters to. The length is the total length the expression or value will be after the padding has been done. It’s not the number of characters to add. The pad_expression is an optional field and is the character or characters to add to the left end of the string. The default value is a space. If the length specified in the function is shorter than the length of the string, then the string is truncated to meet the length. For more information about the Oracle LPAD (and LPAD) function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-lpad/

Oracle SQL Tutorial 1 - Intro to Oracle Database
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.

How to find nth highest salary in SQL Server using a Sub-Query How to find nth highest salary in SQL Server using a CTE How to find the 2nd, 3rd or 15th highest salary Let's use the following Employees table for this demo Use the following script to create Employees table Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) GO To find the highest salary it is straight forward. We can simply use the Max() function as shown below. Select Max(Salary) from Employees To get the second highest salary use a sub query along with Max() function as shown below. Select Max(Salary) from Employees where Salary [ (Select Max(Salary) from Employees) To find nth highest salary using Sub-Query SELECT TOP 1 SALARY FROM ( SELECT DISTINCT TOP N SALARY FROM EMPLOYEES ORDER BY SALARY DESC ) RESULT ORDER BY SALARY To find nth highest salary using CTE WITH RESULT AS ( SELECT SALARY, DENSE_RANK() OVER (ORDER BY SALARY DESC) AS DENSERANK FROM EMPLOYEES ) SELECT TOP 1 SALARY FROM RESULT WHERE DENSERANK = N To find 2nd highest salary we can use any of the above queries. Simple replace N with 2. Similarly, to find 3rd highest salary, simple replace N with 3. Please Note: On many of the websites, you may have seen that, the following query can be used to get the nth highest salary. The below query will only work if there are no duplicates. WITH RESULT AS ( SELECT SALARY, ROW_NUMBER() OVER (ORDER BY SALARY DESC) AS ROWNUMBER FROM EMPLOYEES ) SELECT SALARY FROM RESULT WHERE ROWNUMBER = 3
