Build SELECT / INSERT / UPDATE / DELETE statements with form-based input
WHERE clause builder with 11 operators (=, !=, <, >, LIKE, IN, IS NULL, BETWEEN, …)
ORDER BY, LIMIT, OFFSET, DISTINCT for SELECT
Multiple WHERE conditions joined with AND
**Parametrized mode** emits ? placeholders + a separate params list — what you should bind to your driver's prepared-statement API
Inline mode is illustrative only; the safety banner reminds users not to copy-paste it into production code

Always use parametrized queries / prepared statements in production code. Direct string interpolation of user input is the classic SQL injection vector.
The ? placeholder is the most portable; most SQL drivers (mysql2, sqlite3, pg) accept it. Postgres also uses $1, $2; Oracle uses :name.
Identifiers (table names, column names) generally CANNOT be parametrized in standard SQL — validate them against an allow-list or use a dialect-specific quoting function.
For WHERE IN (...) clauses, generate one placeholder per item: WHERE id IN (?, ?, ?). Most drivers don't expand a single ? to a list.
For dynamic ORDER BY, use a switch / allow-list — don't accept arbitrary column names from user input.
