Dynamic SQL In PostgreSQL || Use Cases And Usage Of Dynamic SQL With Examples Explained In pgAdmin

Dynamic SQL in PostgreSQL | Use Cases and Examples Explained in pgAdmin

In this video, we'll dive into the world of dynamic SQL in PostgreSQL using pgAdmin, exploring various use cases and providing detailed examples to enhance your understanding. Dynamic SQL allows you to construct and execute SQL statements at runtime, offering flexibility and power in database management and manipulation. Here's what we'll cover:

Run-Time DDL Example

Creating a sample table and a stored procedure to add columns dynamically.
Example: Adding a new column email to the employees table.
Run-Time SCL (Session Control)

Setting session variables and roles dynamically.
Examples: Setting the session timezone and changing roles within a session.
Dynamic Columns with Conditions

Filtering data dynamically based on various conditions.
Example: Filtering employees by department using a dynamic WHERE clause.
Dynamic SELECT INTO Queries

Using dynamic SQL to fetch specific column values.
Examples: Fetching salaries based on employee names and dynamically constructing queries with multiple column retrieval.
OPEN Refcursor RETURN Query

Executing dynamic queries and returning results using refcursors.
Example: Returning all employee details using a dynamic query.
Dynamic Multiple-Row Query with Open Loop

Creating and executing queries that return multiple rows using loops.
Example: Fetching all employees from a specific department.
Dynamic DML (Data Manipulation Language)

Updating table data dynamically.
Example: Updating the salary of an employee based on their ID.
By the end of this video, you'll have a solid grasp of how to leverage dynamic SQL in PostgreSQL to perform a wide range of database operations efficiently. Whether you're adding new columns on the fly, setting session parameters, or filtering and updating data dynamically, these examples will provide you with the tools and knowledge to implement dynamic SQL in your own projects.
