Currently, the read-only analysis engine supports most of MySQL's comparison operation logic, but there are still limitations and incompatibilities in certain scenarios. This document introduces supported comparison operations in the read-only analysis engine and enumerates type restrictions on input parameters. Input parameters and usage methods not mentioned in the document are not supported.

Supported Comparison Operation Types
