Struct DropFunction

pub struct DropFunction<'a> {
    pub drop_span: Span,
    pub function_span: Span,
    pub if_exists: Option<Span>,
    pub function: QualifiedName<'a>,
}

Represent a drop function statement

let sql = "DROP FUNCTION myfunc;";
let mut issues = Issues::new(sql);
let mut stmts = parse_statements(sql, &mut issues, &options);

let s: DropFunction = match stmts.pop() {
    Some(Statement::DropFunction(s)) => s,
    _ => panic!("We should get a drop function statement")
};

assert!(s.function.identifier.as_str() == "myfunc");
