EX NO: 3 Date:

HIGH LEVEL LANGUAGE EXTENSION WITH CURSORAIM: To study the PL/SAQL programs and to write the PL/SAQL programs using cursors.

DEFINIYION AND SYNTAX:

1. PL/SQL: PL/SQL stands for procedural structural language/SQL. PL/SQLextends SQL by adding control structures found in other structural languages.PL/SQL can be used in the Oracle relational database in the Oracle server and in the client side application development tools.

SYNTAX: APL/SQL block can divide into three parts namely,

i) Declarative part, ii) Executable part, and iii) Exception handling part.The order is shown below:

DECLARE DeclarationsBEGIN Executable statementsEXCEPTION HandlersEND;

Objects can be declared in declarative part, which can be used in executablepart for further manipulation. All procedural statements are included betweenthe BEGIN and END statements. Errors that occur during the exception are handled by the exception handlers.

2. ATTRIBUTES: Attributes allows us to refer data types and objects from database. PL/SQL constants and variables have attributes. The following are the types of attributes supported by the PL/SQL,

%type %row type


EX NO: 3 Date:

%type: %type is used when declaring variables that refer to database columns. SYNTAX: Variablename tablename.Column %type;

%rowtype: %rowtype attributes provides a record type that rapresents a row in the tablw. The record can store an entire row of data selected from the table or fetched by a cursor.

SYNTAX: Variablename tablename %rowtype;

3. CURSORS: Oracle allocates a memory known as the context area for the processing of the SQL statements. A cursor is a pointer or handle to the context area. Through the cursor, a PL/SQL program can control the context area and what happens to it as the statement is processed.The three types of the cursors are

Static cursors Dynamic cursors REF cursors

Static cursors are the ones whose select statements are known at the compile time. These are further classified into

Explicit cursors Implicit cursors

/*PL/SQL block to perform arithmetic operations*/SQL>declarea number;b number;su number;dif number;pro number;div number;begina:=&a;b:=&b;su:=a+b;dbms_output.put_line(‘The Sum is’||su);


EX NO: 3 Date:

dif:=a-b;dbms_output.put_line(‘The Difference is’||dif);pro:=a*b;dbms_output.put_line(‘The Product is’||pro);div:=a/b;dbms_output.put_line(‘The Quotent is’||div);end;

OUTPUT:

Enter value for a: 25Old 9:a:=&a;New 9:a:=25;Enter value for b: 4Old 10:b:=&b;New 10:b:=4;The Sum is 29The Difference is 21The Product is 100The Quotent is 6.25

PL/SQL procedure successfully completed.

RESULT: Thus the PL/SQL program using the cursors were executed successfully.


PANDUR, THIRUVALLUR DISTEX NO: 4 Date:

HIGH LEVEL LANGUAGE EXTENSIONS WITH TRIGGERS

AIM: To study and execute Triggers in RDBMS. DEFINITION & SYNTAX:

TRIGGER: A database trigger is stored procedure that is fired when an insert, update or delete statement is issued against the associated table. Database triggers can be used for the following purposes.

To generate data automatically. To enforce complex integrity constraints. To customize complex security authorizations. To maintain replicate tables. To audit data modifications.

Syntax for creating Triggers: Create or Replace trigger<trigger name> [before/after][insert/update/delete] on <table_name> [for each statement/for each row] [when <condition>]

Types of Triggers: The triggers are classified into the following types based on when they are fired:

Before After For each row For each statement (default)

INSERT: --create or replace trigger ins1 before insert on emp --begin --raise_application_error(-20001.’you cannot insert a row’); --end;OUTPUT:SQL>insert into emp values(&eid,’&name’,’&dob’,’&addr’,’&sex’,’&dept’,’&salary); insert into emp values(&eid,’&name’,’&dob’,’&addr’,’&sex’,’&dept’,’&salary);


PANDUR, THIRUVALLUR DISTEX NO: 4 Date:ERROR at line 1:ORA-20001: you cannot insert a rowORA-06512: at “SCOTT.ins1”, line 2ORA-04088: error during execution of trigger ‘SCOTT.ins1’

DELETE: --create or replace trigger del1 before delete on emp --begin --raise_application_error(-20001.’you cannot delete a row’); --end;OUTPUT:

SQL>delete from emp where eid=2387; delete from emp where eid=2387;

ERROR at line 1:ORA-20001: you cannot delete a rowORA-06512: at “SCOTT.del1”, line 2ORA-04088: error during execution of trigger ‘SCOTT.del1’

UPDATE: --create trigger upd1 before update on emp for each row --begin --raise_application_error(-20001.’you cannot update a row’); --end;OUTPUT:

SQL>update emp set salary=5000 where eid=321; update emp set salary=5000 where eid=321;

ERROR at line 1:ORA-20001: you cannot update a rowORA-06512: at “SCOTT.upd1”, line 2ORA-04088: error during execution of trigger ‘SCOTT.upd1’

RESULT: Thus the usage of trigger were studied and executed in RDBMS.


EX NO: 5 Date:PROCEDURES AND FUNCTIONS

AIM: To study and execute the procedures and functions in PL/SQL.

PROCEDURES: A procedure is a subprogram that performs a specific action.The syntax for creating a procedure is given below. create or replace procedure <Proc_name> [parameter list] is <local declarations>; begin (executable statements) [exception] (exception handlers) end; A procedure has two parts namely, specification and body. The procedure specification begins with keyword procedure and ends with procedure name or parameter list. The procedure body begins with keyword is and ends with the keyword end. It can also include declarative, executable and exceptional parts with in the keywords are and end. Syntax to execute a procedure is given below.

SQL> exec <proc_name> (parameters);

FUNCTIONS: A function is a subprogram that computes a value. The syntax for creating a function is given below. create or replace function <function_name> [argument] return datatype is (local declaration) begin (executable statements) [exception] (exception handlers) end;


EX NO: 5 Date:where arguments can be in, out or inout. Similar to a procedure, a function also has two parts namely, the function specification and the function body. The function specification begins with the keyword function and ends with the return clause. The function body begins with the keyword is and ends with the keyword end. A PL/SQL block can also be included in a function body.

create or replace function factorial(n number) return number isfac number;i number;beginfac:=1;for I in 1…nloopfac:=fac*i;end loop;return fac;end;//Function created.declaren number;x number;beginn:=&n;x:=factorial(n);dbms_ouytput.put_line(‘the factorial of ‘||n||’is’||x);end;

OUTPUTSQL>/Enter value for n: 5Old 5:n:=&n;New 5:n:=5;The factorial of 5 is 120PL/SQL procedure successfully completed.

RESULT: Thus the procedures and functions were studied and executed in PL/SQL.


EX NO: 6 Date:EMBEDDED SQL

To convert a table to 1 NF remove all the multi valued & composite attributes from the table.

b. Converting a table to 2 NF:

i. Find and remove attributes that are functionally dependent on only a part of the key and not on the whole key. Place them in a different table.

ii. Group the remaining attributes.NORMALIZING THE TABLE TO 1 NF:

EX NO: 10 Date:DESIGN AND IMPLEMENTATION OF PAYROLL PROCESSING SYSTEM

AIM:To develop an employee payroll system using Oracle as a back end (database) and Microsoft

Visual Basic6.0 as a front end.PROCEDURE:

1.Create a employee database with the following fields in oracle namely Empno,Empname,address,Basicpay and insert some record into the database.

2.Design the corresponding form with labels,text boxes and command buttons.

Form1 Employee Payroll

3.Create the back with the front end using DAO method by creating a DSN as follows, a.Select administrative tools option from control panel.

Then click on Data Source(ODBC),which displays a dialog box named ODBC DATASOURCES ADMINISTRATOR in which click Add button.

b.In Create New Data Source dialog box,select “Microsoft ODBC for ORACLE” and click finish button

.c.Give a suitable data source name,user name and server name.

4.Perform the required operations like Insert,Delete,Searching,Modify and Exit.

5.Calculate the net salary of the employee.

6.Execute the project.
