Macro raw_query 

macro_rules! raw_query {
    ($sql:expr) => { ... };
    ($sql:expr, $($params:expr),+ $(,)?) => { ... };
}

A macro for creating raw SQL queries with inline parameter binding.

Example

let sql = raw_query!("SELECT * FROM users WHERE id = {} AND active = {}", user_id, true);

The {} placeholders are replaced with database-specific parameter markers ($1, $2, etc. for PostgreSQL, ? for MySQL/SQLite) and the values are bound as parameters.
