Root Cause

Using database-specific SQL constructs (e.g., MySQL functions) with a different database backend that does not support them.

generic

中文

使用了特定于数据库的 SQL 构造（例如 MySQL 函数），但后端数据库不支持。

Workarounds

  1. 90% success Use generic SQLAlchemy functions 
    Use SQLAlchemy's generic functions like func.now() instead of MySQL-specific NOW().
  2. 85% success Use compatible backend 
    Switch to a compatible database backend or use database-specific dialects with proper abstraction.

Dead Ends

Common approaches that don't work:

  1. Changing dialect only 60% fail

  2. Using raw SQL blindly 50% fail
