use crate::codegen::syntax_tree_pysql::{Name, NodeType, ToHtml};

/// Represents a `for` loop node in py_sql.
/// It iterates over a collection and executes the nested SQL block for each item.
///
/// # Attributes
///
/// - `collection`: The expression providing the collection to iterate over.
/// - `item`: The name of the variable to hold the current item in each iteration.
/// - `index`: The name of the variable to hold the current key/index in each iteration.
///
/// # Example
///
/// PySQL syntax:
/// ```py
/// for item in ids:
///   AND id = #{item}
///
/// for key, item in user_map:
///   (#{key}, #{item.name})
/// ```
