PL/SQL BASIC SYNTAX

PL/SQL BASIC SYNTAX encompasses declaring variables, writing procedural constructs like loops and conditional statements (IF-THEN-ELSE, CASE), and using SQL commands (SELECT, INSERT, UPDATE, DELETE) within Oracle database programs. It supports error handling through EXCEPTION blocks and allows defining procedures, functions, triggers, and packages, facilitating structured and efficient database operations.

DECLARE Block:

This is where you declare variables, types, cursors, and other  PL/SQL constructs.

DECLARE

   -- Variable declaration

   my_variable NUMBER;

 

BEGIN...END Block:

This is where you write the executable part of your PL/SQL code.

BEGIN

   -- PL/SQL code goes here

END;
