Understanding the Issue

1. Empty String (""): An empty string is a valid string value with zero length. It represents a deliberate absence of content.

2. Null Value (null): Null in programming languages (and databases) typically represents a lack of value or an undefined state. It’s different from an empty string, which is a valid, defined string value with zero length.
