Oracle Cursor and Trigger

Cursor: cursor is a private sql work area. Every sql statement executed by oracle server has an individual cursor associated with it.
Cursor are two types
1.Implicit cursor
2.Explicit cursor
Implicit cursor: Implicit cursors are declared by pl/sql implicitly at the time of DML statement and select statement in pl/sql including queries that returns single row.
Cursor have four attributes
1. SQL%ROWCOUNT
2. SQL%ISOPEN
3. SQL%NOTFOUND
4. SQL%FOUND

SQL%ROWCOUNT-Basically it returns  number. means number of rows affected by present sql statement.
SQL%ISOPEN-Always evalutes false because implicit cursor automatically closed after execution of sql statement.
SQL%FOUND-Always evalutes true because one or more rows are affected by recent sql statement
SQL%NOTFOUND-Always evalutes true when no rows are affected by present sql statement.

Example of explicit cursor
DECLARE
v_empno employees.employee_id%TYPE;
v_name employees.last_name%TYPE;
CURSOR emp_cur IS
SELECT employee_id,last_name FROM employees
BEGIN
OPEN emp_cur;
LOOP
FETCH emp_cur INTO v_empno,v_name ;
EXIT WHEN emp_cur%ROWCOUNT>10 OR
emp_cur%NOTFOUND;

DBMS_OUTPUT.PUT_LINE('employee_id:'||TO_CHAR(v_empno) || 'employee_name:'||'v_name');

END LOOP;
CLOSE emp_cur;
END;

Trigger Trigger is pl/sql block or procedure that is associated with table,view,schema and database. Execute immediately when particular event take place.
There are two types of trigger
1.Application trigger: Fires automatically when event occurs with particular application.
2.Database trigger: Fires when data such as DML oparation occured at that time.
DML triggers are two types
   1.Statementlevel trigger
   2.Rowlevel trigger

Statement level trigger -Statement level trigger means trigger body execute once for the triggering event.this is default.A statement level trigger fire once even no rows are affected at all.
Row level- Trigger body execute once for each row affected by triggering event.if no rows are affected in that case trigger body not executed.

Trigger example:
CREATE OR REPLACE TRIGGER secure_emp
BEFORE INSERT ON employees
BEGIN
TO_CHAR(SYSDATE,'DY')IN('SUN','SAT') OR TO_CHAR((SYSDATE,'HH24:MI')NOT BETWEEN '08:00' AND '18:00')THEN
RAISE_APPLICATION_ERROR(-20253,'u may insert employee information at business hrs');
END;

How to Load Oracle Workflow definition

The Workflow Definitions Loader is called WFLOAD and can be found in: $FND_TOP/bin

By default it can be used the following ways.
To upload:      WFLOAD apps/pwd 0 Y UPLOAD file.wft
To force:         WFLOAD apps/pwd 0 Y FORCE file.wft
To download: WFLOAD apps/pwd 0 Y DOWNLOAD file.wft ITEMTYPE1 [ITEMTYPE2...ITEMTYPEn]
To upgrade:    WFLOAD apps/pwd 0 Y UPGRADE file.wft

You can use a concurrent program to load process definitions. Run Workflow Definitions Loader concurrent program

What is NOCOPY hint?

Prior to Oracle 8i there were three types of parameter-passing options to procedures and functions:
    * IN: parameters are passed by reference
    * OUT: parameters are implemented as copy-out
    * IN OUT: parameters are implemented as copy-in/copy-out

The technique of OUT and IN OUT parameters was designed to protect original values of them in case exceptions were raised so that changes could be rolled back. Because a copy of the parameter set was made rollback could be done. However this method imposed significant CPU and memory overhead when the parameters were large data collections for example PL/SQL Table or VARRAY types.

With the new NOCOPY option OUT and IN OUT parameters are passed by reference which avoids copy overhead. However parameter set copy is not created and in case of an exception rollback cannot be performed and the original values of parameters cannot be restored.

Here is an example of using the NOCOPY parameter option:

TYPE Note IS RECORD( Title VARCHAR2(15), Created_By VARCHAR2(20), Created_When DATE, Memo VARCHAR2(2000));
TYPE Notebook IS VARRAY(2000) OF Note;
CREATE OR REPLACE PROCEDURE Update_Notes(Customer_Notes IN OUT NOCOPY Notebook) IS BEGIN ...END;

16. What is the use of cursors in PL/SQL? What is REF Cursor?
The cursor is used to handle multiple row query in PL/SQL. Oracle uses implicit cursors to handle its queries. Oracle uses unnamed memory spaces to store data used in implicit cursors, with REF cursors you can define a cursor variable, which will point to that memory space and can be used like pointers in our 3GL’s

An Autonomous transaction is an independent transaction started by another transaction , the main transaction ,Autonomous transaction lets you suspend the main transaction do SQL operations ,commit or rollback those operation then resume the main transaction Once started an autonomous transaction fully independent .It shares no locks ,resources .or commit dependencies with the main transaction so ,you can log events increment retry counters ,and soon even if the main transaction rolls back More important, Autonomous transaction help you build modules reusable software component . for example Stored procedures can start and finish autonomous transaction there own .A calling application need not know about a procedures autonomous operations, and the procedures need not know about the application transaction content.

Scenario: you can use autonomous transaction in your report for writing error message in your database table.

What is $FLEX$ and $PROFILES$?

$FLEX$ and $PROFILES$ are Special Variables in oracle Apps environment and are used to hold values at runtime. Whenever we are working with value sets, we will be using both of these for modifying the data fetched, for basing the values of a parameter on the other parameter and also fetching the Profile Option values.

To segregate this based on the functionality
$FLEX$: Used for basing the value of a parameter on another parameter.
$PROFILES$: used for fetching the data stored in the specified profile option value which is currently active.

Where is it used?

Both these variables are used in the Parameter form of a Concurrent Program and are used at the Where Clause window in the value set of Table type.

Syntax:

:$FLEX$.previous_value_set_name

Important:

    * $FLEX$ must always be in capitals.
    * A ':' must precede the declaration of $FLEX$.
    * The previous value set name must have already been assigned and saved on a different parameter.


:$PROFILES$.Profile_option_name

Important:

    * $PROFILES$ must be always in capitals.
    * ':' must always precede the declaration.
    * Profile option name is the Profile Name and not to be confused with the User profile Name.

How to Call OAF Page from Workflow Email Notification

In R12  below error will occur if you try to open an OAF Page URL link directly.

You are trying to access a page that is no longer active. The referring page may have come from a previous session. Please select Home to Proceed.

Note: When you call a standard page this error won't appear. This happens only when you try to open a custom page.

Below are the steps to resolve the error:
1.Open the custom page in Jdev and select the PageLayoutRN. In the property inspector set the Security Mode to selfSecured.
2.Set the rendered property to ${oa.FunctionSecurity.}
Eg: ${oa.FunctionSecurity.XXCUSTPG}
Note: Your user id should have access to the custom page function.
3.In your workflow procedure generate the  OA page URL with the below function and set the workflow attribute with the generated URL.

lc_url:= FND_RUN_FUNCTION.get_run_function_url(p_function_id => 53637,
p_resp_appl_id => null,
p_resp_id => null,
p_security_group_id => 0,
p_parameters =>'PARAM1='||p_lease_id,--'&'||'LeaseId=784',
p_override_agent => null,
p_org_id => null,
p_lang_code => null,
p_encryptParameters => false);

Now you should be able to open the OAF page from workflow email notification.
