MySQL Error 1272: Invalid Variable Component Usage

📋

Description

This error occurs when a variable is referenced using a dot notation (e.g., `schema.variable_name`) as if it were a component of a database object, but it is not. MySQL expects direct access for variables like user-defined, session, or global variables, not a qualified path.

Confusing Variables with Objects

Mistaking a variable name for a column or table name, leading to an incorrect qualified reference in a query or statement.
