About this pattern
These patterns detect common SQL injection keywords and patterns: SQL commands (SELECT, INSERT, DROP), comment sequences (--), and statement terminators (;). Important: regex-based detection is a defense-in-depth layer, NOT a primary defense. Always use parameterized queries/prepared statements as your primary SQL injection prevention.
FAQ
Is regex enough to prevent SQL injection?
Absolutely not. Regex is a supplementary detection layer. Your primary defense must be parameterized queries (prepared statements), which make SQL injection structurally impossible regardless of input content.
