What is Difference between Decode and Case?

Decode
1.It’s a function
2.can compare only discrete vaules
3.Pl/Sql standards
4.cannot process null

Case
1.It’s an Expression
2.can hande range values
3.ANSI Standards
4.Processing time is faster when compared to Decode
5.can process null

Decode
The default operator for comparison is ‘=’,
for e.g select deptno,decode
(deptno,10,’dept10′,20,dept20,default)

so if the deptno=10 then the value is replaced by dept10
and so on,

whereas in Case:

we can use any operator other than ‘=’,
for e.g
select deptno,
case when deptno=10 and sal>1000 then ‘dept10’
else
‘dept20’

Decode: using for reporting purpose. and it is implemented
by if stmt.
Ex: select decode(job,’CLERK’,’executive’,job) from emp;

Case : implemented by if & elsif condition. it is using
pl/sql equality conditionality.
Ex : select case job=’CLERK’ then ‘executive’ else ‘no’ end
a from emp;

it is also used for multipul colms & multi conditions.

in above stmt a is reffered alias name.

There is one more Important difference between CASE and DECODE

DECODE can be used Only inside SQL statement….
But CASE can be used any where even as a paramtre of a function/procedure

Eg:-

Code: [Select all] [Show/ hide]SQL> create or replace procedure pro_01(n number) is
2 begin
3 dbms_output.put_line(‘ The number = ‘||n);
4 End;
5 /

Procedure created.

SQL> set serverout on
SQL> var a varchar2(5);
SQL> Begin
2 :a := ‘ONE’;
3 End;
4 /

PL/SQL procedure successfully completed.

SQL> Begin
2 pro_01(Decode(:a,’ONE’,1,0));
3 End;
4 /
pro_01(Decode(:a,’ONE’,1,0));
*
ERROR at line 2:
ORA-06550: line 2, column 9:
PLS-00204: function or pseudo-column ‘DECODE’ may be used inside a SQL
statement only
ORA-06550: line 2, column 2:
PL/SQL: Statement ignored

SQL> Begin
2 pro_01(case :a when ‘ONE’ then 1 else 0 end);
3 End;
4 /
The number = 1

PL/SQL procedure successfully completed.

What are Components of Oracle Workflow?

Components of Oracle Workflow :

Workflow Builder
Workflow Engine
Workflow Definitions Loader
Notification Systems
Workflow Monitor
Notification systems
Business Event System’s
Workflow XML Loader

Directory Service’s.

Workflow Builder :Work Flow builder is a Graphical interface to create and modify a business process with simple drag and drop operations.
It has two components –
* Navigator Window
* Process Window
A workflow builder would be used by a person to design and modify a workflow. It is more of a designer’s tool rather than an end-user’s tool.

Workflow Engine : The Workflow Engine embedded in the Oracle8 server monitors workflow states and coordinates the routing of activities for a process.Changes in workflow state, such as the completion of workflow activities, are signaled to the engine via a PL/SQL API or a Java API. Based on flexibly–defined workflow rules, the engine determines which activities are eligible to run, and then runs them. The Workflow Engine supports sophisticated workflow rules, including looping, branching,parallel flows, and sub-flows.

Workflow Definitions Loader :The Workflow Definitions Loader is a utility program that moves workflow definitions between database and corresponding flat file representations.It allows opening and saving workflow definitions in both a database and file.

Notification System : Each notification includes a message that contains all the information a user needs to make a decision.

Workflow Monitor : The Workflow Monitor displays an annotated view of the process diagram for a particular instance of a workflow process.Users can get a graphical depiction of their work item status. It also displays a separate status summary for the work item, the process, and each activity in the process.
