Prompt Engineering Cannot Truly Secure LLM-Generated SQL

Recently, many teams are working on Text-to-SQL, ChatBI, or data analysis Agents. One underestimated issue is that SQL generated by LLMs should not directly enter production databases.
This article discusses: addressing the common misconception that "prompt rules can control generated SQL," and explaining why pre-execution validation is still necessary.
Key points:
Prompts can guide the model, but cannot enforce database security.
Generated SQL requires deterministic pre-execution validation.
The correct pattern is prompt guidance + parser/catalog/policy/audit checks.
