Oracle NVL Function Explained with Examples
 
09:25
https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/ The Oracle NVL function allows you to check a value and return a different value if that value is NULL. It’s great for using another value if the first one is NULL or an optional value, for example people’s phone numbers. It’s also good alongside aggregate functions and grouping so you can see what the difference is between a subtotal row and an actual NULL value. The syntax of the Oracle NVL function is: NVL( check_value, replace_value ) The parameters are: - check_value (mandatory): This is the value that is displayed to the user. It is also the value that is checked for NULL. - replace_value (mandatory): This is the value that appears if the check_value is NULL. The function can use many different data types as parameters: string, date, or numeric. However, both parameters need to be the same type. For more information about the Oracle NVL function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/

PL/SQL:NVL/NVL2/Coalesce function
 
05:26
In this tutorial, you'll learn the difference between NVL,NVL2 &Coalesce functions 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.

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

Oracle NVL2 Function
 
03:05
https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/ The Oracle NVL2 function is an extension of the NVL function and can be used to handle NULL values. It allows you to specify a value to check for NULL, a separate value to return if the value is NULL, and another value to return if the first value is not NULL. It’s very similar to NVL but allows for more flexibility. The syntax for NVL2 is: NVL2( value_to_check, value_if_not_null, value_if_null ) What are these parameters: Value_to_check is the value the function checks to see if it is NULL. Value_if_not_null is the value to return if the first value, value_to_check, is not NULL. Value_if_null is the value to return if the first value, value_to_check, is NULL. These parameters can have almost any data type (the second and third parameter can’t be a LONG data type). Oracle will determine the data type from the supplied parameters. There are quite a few of these conditional checking functions in Oracle, so the one to use would depend on your needs. But it’s good to know this function exists. For more information about the Oracle NVL2 function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/

NVL Function in SQL Query
 
04:04
NVL(): The Oracle/PLSQL NVL function lets you substitute a value when a null value is encountered. Syntax: NVL( string1, replace_with ) Arguments: string1 is the string to test for a null value. replace_with is the value returned if string1 is null. Example: Let's look at some Oracle NVL function examples and explore how you would use the NVL function in Oracle/PLSQL. For example: select NVL(comm, 'n/a') from emp; The SQL statement above would return 'n/a' if the 'comm' field contained a null value. Otherwise, it would return the 'comm' value. Lets have a look on emp table. Here for manager and comm columns we have null data. In output, I am getting null values. By using NVL function i can omit these null values in output.

[,default] ) The parameters of the Oracle DECODE function are: - expression (mandatory): This is the value to compare. - search (mandatory): This is the value to compare against the expression. - result (mandatory): This is the return value if the search value matches the expression value. There can be multiple combinations of search and result values, and the result value is attached to the previous search value. - default (optional): If none of the search values match, then this value is returned. If this is not provided, the DECODE function will return NULL if no matches are found. If you compare this to an IF-THEN-ELSE statement, it would look like this: IF (expression = search) THEN result [ELSE IF (expression = search) THEN result] ELSE default END IF The parameters can be one of many different data types, and the return type is calculated from them. Earlier I mentioned it’s similar to CASE. So why would you use one and not the other? - DECODE is an older function, and CASE was introduced as a replacement for DECODE. - CASE offers more flexibility then DECODE - CASE is also easier to read and debug (in my opinion) The performance of these functions is the same, so if you’re considering using DECODE, I would suggest using CASE instead.
