ParsedStatement

uqa_sql::compiler

Struct ParsedStatement 

Source 
pub struct ParsedStatement<'sql> { /* private fields */ }
Expand description

A syntactically valid statement retaining its exact source slice. Compilation is separate so an execution boundary can analyze statements in order after preceding commands have completed.

Implementations§

Source§

impl<'sql> ParsedStatement<'sql>

Source

pub const fn sql(&self) -> &'sql str

Original SQL, without reconstructing or rewriting the parser tree.

Source

pub fn is_notification_listener_command(&self) -> bool

Identify a direct LISTEN or UNLISTEN without semantic compilation or inspecting strings and routine bodies. Nested commands must still be checked when executed.

Source

pub fn compile(&self) -> Result<Statement>

Compile this statement into the engine’s internal SQL representation.
