Oracle - Procedures
A Procedure is a subprogram unit that consists of a group of PL/SQL statements. Each procedure in Oracle has its own unique name by which it can be referred. This subprogram unit is stored as a database object.
A procedure is a group of PL/SQL statements that can be called by name. The call specification (sometimes called call spec) specifies a java method or a third-generation language routine so that it can be called from SQL and PL/SQL.
Syntax :
CREATE [OR REPLACE] PROCEDURE procedure_name
[ (parameter [,parameter]) ]
IS
[declaration_section]
BEGIN
executable_section
[EXCEPTION
exception_section]
END [procedure_name];
Following are the three types of procedures that must be defined to create a procedure.
In this example, we are going to insert record in the "user" table. So you need to create user table first.
create table user(id number(10) primary key,name varchar2(100));
Now write the procedure code to insert record in user table.
create or replace procedure "INSERTUSER"
(id IN NUMBER,
name IN VARCHAR2)
is
begin
insert into user values(id,name);
end;
/
Procedure created.
Let's see the code to call above created procedure.
BEGIN
insertuser(101,'Rahul');
dbms_output.put_line('record inserted successfully');
END;
/
Now, see the "USER" table, you will see one record is inserted.
| ID | Name |
|---|---|
| 101 | Rahul |
DROP PROCEDURE procedure_name;
DROP PROCEDURE pro1;
