SqlBodyTableUdf

Struct SqlBodyTableUdf 

Source 
pub struct SqlBodyTableUdf { /* private fields */ }
Expand description

A TableUdf whose body is a SQL query executed via a DataFusion session.

Created by SqlEngine when CREATE FUNCTION … LANGUAGE sql AS '…' is processed. Uses block_in_place so the sync TableFunctionImpl::call() can safely block on async SQL execution without deadlocking the runtime.
