Implementations§

Source§

impl Select

Source

pub fn select_names(&self) -> Vec<String>

return the column names selected does not return functions.

Source

pub fn select_alias(&self) -> Vec<Identifier>

return the aliased column names. If the column is not aliased the base column name is returned. does not return functions.
