sea-query

Enables runtime query building with a fluent interface, using methods like `apply_if` to conditionally add clauses without manual string concatenation, as shown in the README's dynamic query example.

Automatically handles parameter sequencing to prevent SQL injection and 'off-by-one' errors, demonstrated in examples where values are injected with proper $N placeholders.

Provides a unified API for MySQL, PostgreSQL, and SQLite, allowing single-source query logic with backend-specific adjustments, evident in the ON CONFLICT clause examples.

Supports arbitrarily nested WHERE/HAVING conditions using `Cond::any()` and `Cond::all()`, respecting operator precedence without cluttering parentheses, as illustrated in the condition builder section.
