Reviewed separation of SQL structure from parameter-bound data values and separate handling of dynamic identifiers.
Authorization and destructive-query review remain separate controls.
active
Use parameterized SQL for untrusted data values
Building SQL strings with untrusted values creates injection and quoting vulnerabilities.
Current Best
Keep SQL structure in the query and pass data values through the database drivers parameter mechanism. Validate dynamic table or column identifiers separately because value placeholders do not parameterize identifiers. Parameterization prevents quoting and injection mistakes but does not replace authorization, transaction design or destructive-query review.
