SQL with inline literals

Single-quoted strings and standalone numbers become placeholders. NULL, TRUE/FALSE, identifiers, comments and existing placeholders are left untouched.
About this tool
IconVault's SQL Parameterizer converts risky inline values into safe placeholders. Paste SQL with hard-coded strings and numbers and it rewrites them as ?, $1, :p1 or @p1 style parameters, depending on your database, and hands you an ordered parameter list with the original values, ready to bind in your code.
It runs 100% in your browser and is free, leaving NULLs, TRUE/FALSE, identifiers, comments and existing placeholders untouched. It is a text rewriting helper, not a security auditor: always review the output and keep using your driver's parameter binding rather than string concatenation.
