Erros comuns e correções
| Sintoma | Causa provável | Correção |
|---|---|---|
| The destination still reports invalid syntax. | The text was escaped for a different language or embedding layer. | Select the exact destination context and avoid double escaping. |
| Escaped SQL is treated as safe application code. | Literal escaping alone does not handle query structure or driver behavior. | Use bound parameters for database values. |
