Struct DropDatabase 

pub struct DropDatabase {
    pub spelling: DatabaseKeyword,
    pub if_exists: bool,
    pub name: Ident,
    pub meta: Meta,
}

DROP {DATABASE | SCHEMA} [IF EXISTS] <name> — MySQL’s single-database drop, where DATABASE and SCHEMA are exact synonyms (the lexer folds SCHEMA onto DATABASE). Kept apart from the generic name-list Statement::Drop because the form names exactly ONE unqualified database — server-measured on mysql:8, DROP DATABASE a, b is ER_PARSE_ERROR, DROP DATABASE db.x is ER_PARSE_ERROR, and it takes no CASCADE/RESTRICT (both syntax errors) — unlike PostgreSQL/DuckDB’s DROP SCHEMA <name> [, …] [CASCADE | RESTRICT], which keeps riding the shared DropStatement grammar there. Gated by StatementDdlGates::drop_database.

Fields

spelling: DatabaseKeyword

Which of the two synonymous keywords was written; recorded so the source spelling round-trips verbatim (the tag pattern of TemporaryTableKind, not a semantic difference — MySQL treats the two identically).

if_exists: bool

Whether the IF EXISTS guard was written.

name: Ident

The single database name — a bare unqualified identifier (ident; a dotted db.x is a server syntax error).

meta: Meta

Source location and node identity.

Trait Implementations

impl Clone for DropDatabase

fn clone(&self) -> DropDatabase

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DropDatabase

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DropDatabase

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for DropDatabase

impl Hash for DropDatabase

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Render for DropDatabase

fn render(&self, ctx: &RenderCtx<'_>, f: &mut Formatter<'_>) -> Result

Return the render for this value.

fn operand_binding_power(&self) -> Option<BindingPower>

The binding power this node contributes when it appears as an operand, or None (the default) for a self-delimiting node — an atom, call, or constructor — that never needs parentheses.

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Spanned for DropDatabase
