Struct DropIndex

pub struct DropIndex<'a> {
    pub drop_span: Span,
    pub index_span: Span,
    pub if_exists: Option<Span>,
    pub index_name: Identifier<'a>,
    pub on: Option<(Span, QualifiedName<'a>)>,
}

Represent a drop index statement.

MariaDB example

let sql = "DROP INDEX IF EXISTS `myindex` ON `bar`;";
let mut issues = Issues::new(sql);
let mut stmts = parse_statements(sql, &mut issues, &options);

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

assert!(s.index_name.as_str() == "myindex");

PostgreSQL example

let sql = "DROP INDEX IF EXISTS \"myindex\";";
let mut issues = Issues::new(sql);
let mut stmts = parse_statements(sql, &mut issues, &options);

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

assert!(s.index_name.as_str() == "myindex");
