Plus, if you’re in Coimbatore and eager to get hands-on training with placement opportunities, Sparkdatabox offers top-tier Oracle PL/SQL training to jumpstart your career.

PL/SQL Block Structure

Every PL/SQL program is built from blocks. Understanding the structure of these blocks is the first step in mastering PL/SQL. A PL/SQL block is divided into three main sections:

  1. Declaration Section: Here, you declare variables, constants, cursors, and other elements.
  2. Execution Section: This is where the actual code resides, performing the necessary operations.
  3. Exception Handling Section: This optional section is used to handle errors that occur during execution.
  4. PL/SQL supports various data types, enabling you to store and manipulate different kinds of data effectively. Key data types include:
    • Scalar TypesNUMBERVARCHAR2CHARDATEBOOLEAN
    • Composite TypesRECORDTABLE
    • Reference TypesREF CURSOR
    • LOB TypesBLOBCLOB

    Variables and constants are crucial for storing data temporarily during program execution.

    Writing Anonymous Blocks

    Anonymous blocks are unnamed PL/SQL blocks that can be written and executed without being stored in the database.

    Anonymous blocks are ideal for quick tests and one-time operations. They are straightforward and efficient for tasks that do not require repeated execution.
