Implementations

impl SqlOrderByComponent

pub fn to_mysql_order_by_clause_component<'a>( &self, s: &'a mut String, ) -> &'a str

Generate an ORDER BY component for MySQL.

`<table_name>`.`<column_name>` <order_type>

pub fn format_mysql_order_by_components<'a>( order_by_components: &[SqlOrderByComponent], s: &'a mut String, ) -> &'a str
