Struct CallStatement 

pub struct CallStatement<X: Extension = NoExt> {
    pub name: ObjectName,
    pub args: ThinVec<Expr<X>>,
    pub parenthesized: bool,
    pub meta: Meta,
}

A CALL <name> [ ( [ <arg> [, ...] ] ) ] routine invocation (DuckDB, MySQL; gated by UtilitySyntax::call).

Invokes a table function or stored procedure as a top-level statement (CALL pragma_table_info('t'), CALL my_proc(1, 2)). The arguments are full expressions, which makes this node generic over the extension X.

The parenthesized argument list is mandatory for DuckDB — it rejects a bare CALL pragma_version (syntax error) but accepts an empty CALL pragma_version() — and optional for MySQL, whose grammar (CALL_SYM sp_name opt_paren_expr_list) admits a bare CALL my_proc with no argument list at all (verified on mysql:8.4.10 — the bare form resolves to ER_SP_DOES_NOT_EXIST, a grammar-positive binding reject). The parenthesized surface flag distinguishes the two written forms so the source round-trips: false is the MySQL bare form (CALL p, always empty args), true is the parenthesized form (CALL p() / CALL p(1, 2), which is the only DuckDB shape). The bare form is gated by UtilitySyntax::call_bare_name.

Fields

name: ObjectName

Name referenced by this syntax.

args: ThinVec<Expr<X>>

The argument expressions, in source order; may be empty (CALL f()) when parenthesized is true, and is always empty for the bare MySQL form (CALL f).

parenthesized: bool

Whether a parenthesized argument list was written. true renders the (...) (empty or not); false is the MySQL bare CALL name form with no argument list, which renders just the name. Always true for DuckDB, whose parentheses are mandatory.

meta: Meta

Source location and node identity.
