Struct ShowStatement 

pub struct ShowStatement<X: Extension = NoExt> {
    pub target: ShowTarget<X>,
    pub meta: Meta,
}

A typed SHOW TABLES utility statement (MySQL/DuckDB; gated by ShowSyntax::show_tables).

Distinct from the generic session SHOW <var> (SessionStatement::Show), which reads one configuration parameter, and from the parenthesized (SHOW <name>) table source (TableFactor::ShowRef), which only appears inside a FROM (…) and produces a relation. SHOW TABLES is a top-level catalogue-listing statement, so it is its own node — the MECE split spelled out on show_tables.

This is the opener of the typed-SHOW family (SHOW COLUMNS, SHOW CREATE TABLE, SHOW FUNCTIONS join it): the listed thing rides the ShowTarget axis. That axis is an enum with per-variant fields — the SessionStatement / ShowRefTarget idiom, not a flat kind tag like ApplyKind: the SHOW subforms carry genuinely different payloads (TABLES takes a FROM/filter, CREATE TABLE a table name, FUNCTIONS a scope keyword, schema qualifier, and name-or-regex filter), so a shared tag would force an option-soup lowest common denominator. A sibling is then a new ShowTarget variant plus its own gate, leaving the existing variants untouched.

Fields

target: ShowTarget<X>

Object targeted by this syntax.

meta: Meta

Source location and node identity.

Trait Implementations

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<X: Debug + Extension> Debug for ShowStatement<X>

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