FAQ
What does this tool tell you?
The SQL Injection Pattern Reference covers classic, union-based, boolean blind, time-based blind, and second-order injection techniques with parameterized query and ORM defense guidance.
What affects the result most?
Classic SQLi: ' OR '1'='1 — boolean injection, extracts data or bypasses WHERE. Union-based: UNION SELECT username, password FROM users — extracts data via response. Blind SQLi: boolean-based (different response on true/false) and time-based (SLEEP/WAITFOR).
How should I use the result?
Use this tool to orient quickly to the concepts, field names, or values you are about to look up in a full specification or vendor documentation. It summarizes the common cases; the authoritative source remains whichever standard or vendor doc defines the values themselves.
