pub fn lower_select_statement(
statement: &Statement,
) -> Result<MirGraph, SqlError>Expand description
Lowers an already-parsed SELECT Statement into an MirGraph.
Skips the byte-budget check (the input is no longer textual at this
point) but still produces graphs that should be size-checked by the
caller via enforce_graph_size.
ยงErrors
SqlError::UnsupportedStatement on non-SELECT input, plus any
downstream lowering error.
