Mastering SQL - PostgreSQL: Pre-defined Functions - Extracting Data - substr and split_part

In this tutorial, we explore two essential PostgreSQL string functions: substr and split_part. These functions allow you to extract specific parts of a string based on position, length, and delimiters. Whether you're working with fixed-length strings or variable-length data, you'll learn how to leverage these functions for data manipulation and extraction tasks.

What this video covers:
✔️ Extracting substrings using substr and substring
✔️ Handling fixed-length and delimited strings with split_part
✔️ Using substr for advanced string manipulations
✔️ Practical examples for working with unique IDs and addresses
✔️ Handling data validation with split_part

💡 Master string extraction techniques in PostgreSQL for efficient data management.
