COALESCE Function in SQL ORACLE Query With Example
 
03:53
ORACLE/PLSQL: COALESCE FUNCTION The Oracle/PLSQL COALESCE function returns the first non-null expression in the list. If all expressions evaluate to null, then the COALESCE function will return null. The syntax for the Oracle/PLSQL COALESCE function is: coalesce( expr1, expr2, ... expr_n ) PARAMETERS: expr1 to expr_n are the expressions to test for non-null values. EXAMPLE: The COALESCE function can be used in Oracle/PLSQL. You could use the coalesce function in a SQL statement as follows: SELECT COALESCE( address1, address2, address3 ) result FROM suppliers; The above COALESCE function is equivalent to the following IF-THEN-ELSE statement: IF address1 is not null THEN result := address1; ELSIF address2 is not null THEN result := address2; ELSIF address3 is not null THEN result := address3; ELSE result := null; END IF; The COALESCE function will compare each value, one by one. Lets apply the same to emp table. We have some NULL values in comm and mgr columns. but not in any other columns. So lets take a example for this 2 columns. COALESCE(comm,mgr,sal) Here if comm is null, function returns mgr value. If mgr is null it returns sal value! Query used in video: SELECT ename,comm,mgr,sal,COALESCE(comm,mgr,sal) result FROM emp;

Oracle COALESCE Function
 
04:00
https://www.databasestar.com/oracle-coalesce/ The COALESCE function in Oracle allows you to input one or many values and return a value that is not NULL. You provide it with a series of values, and it returns the first of thsoe values which are not NULL. The syntax of the Oracle COALESCE function is: COALESCE(expr1, expr2 [, expr_n]) These parameters are: Expr1: the first expression to check for a NULL value. If it’s NULL, the function checks the next parameter. If not, then this value is returned. Expr2: the second expression to check for a NULL value, if the first expression is NULL. If this is NULL, then the next expression is checked, otherwise this value is returned. Expr_n: More expressions can be added and checked in case both expr1 and expr2 are null. Only the first two expressions are needed. The first non-NULL expression is returned. But, if all expressions are NULL, then NULL is returned. One way I’ve recently used this was to find out what phone number to display. A query looked at the mobile number and returned that, but if it was NULL it looked at the home phone and returned that, but if that was NULL it looked to the business phone number. That query looked like this: COALESCE(mobile_phone, home_phone, business_phone) For more information about the Oracle COALESCE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-coalesce/

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.

COALESCE IN ORACLE SQL
 
06:50
This video is the 4th video in the series of 'working with null', this video explains the working of the coalesce function in oracle sql. Also the video explains the use of coalesce function in oracle sql queries by perfect simple and easy to understand examples. COALESCE returns the first non-null expr in the expression list. You must specify at least two expressions. If all occurrences of expr evaluate to null, then the function returns null. Oracle Database uses short-circuit evaluation. The database evaluates each expr value and determines whether it is NULL, rather than evaluating all of the expr values before determining whether any of them is NULL. If all occurrences of expr are numeric datatype or any non numeric datatype that can be implicitly converted to a numeric datatype, then Oracle Database determines the argument with the highest numeric precedence, implicitly converts the remaining arguments to that datatype, and returns that datatype.

The Coalesce function from SQL (e.g. SQL-Server, Oracle, MySQL), with its variable number of arguments, is the perfect example to show the purpose and usefulness of the ParamArray keyword for arguments to VBA procedures. - After writing this function yourself, you can use the Coalesce function in Access queries.

[,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.

1) ISNULL() function : We are passing 2 parameters to IsNULL() function. If 1st parameter returns NULL, then 'XYZ' string(2nd parameter) is used as the replacement value. 2) COALESCE() function: COALESCE() function, returns the first NON NULL value. We are passing Col1, Col2 and ColN columns as parameters to the COALESCE() function. The COALESCE() function returns the first non null value from the 3 columns. A) ISNULL() VS COALESCE() :
