Struct DropIndexOnTable 

pub struct DropIndexOnTable {
    pub name: Ident,
    pub table: ObjectName,
    pub options: ThinVec<IndexLockAlgorithmOption>,
    pub meta: Meta,
}

DROP INDEX <name> ON <table> [ALGORITHM [=] {DEFAULT | INPLACE | INSTANT | COPY}] [LOCK [=] {DEFAULT | NONE | SHARED | EXCLUSIVE}] — MySQL’s index drop (drop_index_stmt, sql_yacc.yy). Kept apart from the generic name-list Statement::Drop because it names the owning table with a mandatory ON <table> (server-measured: DROP INDEX i with no ON is ER_PARSE_ERROR on mysql:8) and carries the online-DDL ALGORITHM/LOCK execution hints, neither of which the shared grammar has. The index name is a bare identifier (ident; a dotted i.j is a syntax error) while the table is a possibly-dotted ObjectName (db.t binds). Gated by IndexAlterSyntax::index_drop_on_table.

Fields

name: Ident

The dropped index — a bare unqualified identifier.

table: ObjectName

The table the index belongs to (ON <table>); may be schema-qualified (db.t).

options: ThinVec<IndexLockAlgorithmOption>

The trailing ALGORITHM/LOCK execution hints in source order (opt_index_lock_and_algorithm). The grammar admits at most one of each and both orderings (ALGORITHM … LOCK … or LOCK … ALGORITHM …, server-measured: a repeated ALGORITHM/LOCK is ER_PARSE_ERROR), so this holds zero, one, or two entries and preserves the written order for round-trip.

meta: Meta

Source location and node identity.
