pub fn rewrite_sql_with(sql: &str, ddx: &Ddx) -> Result<String>Expand description
rewrite_sql driven by a caller-supplied engine.
GenericDialect is the parser DataFusion itself uses for SQL, and
Ddx::for_datafusion supplies the matching identifier-folding policy
(unquoted folds, quoted keeps case) — the two must agree or column matching
silently diverges from the engine’s own.
