Does this tool block SQL injection attacks?

No — it is an educational pattern matcher. It highlights suspicious patterns in a pasted query and explains why they are dangerous, helping developers learn to write safer code.

What patterns are detected?

OR/AND tautologies (1=1, 'a'='a'), UNION SELECT extraction, comment injection (-- and /* */), stacked queries (;DROP, ;INSERT), and SLEEP/WAITFOR blind injection probes.

Can this replace a real WAF or parameterised queries?

No. The only real defence against SQL injection is using parameterised queries or prepared statements in your application code. This tool is for learning and auditing, not production security.
