pub fn execute_union(
view: &GraphView<'_>,
union: &UnionQuery,
params: &Params<'_>,
) -> Result<ResultSet, String>Expand description
Execute a read query that may be a UNION / UNION ALL chain. Each part is
planned and executed against the same view (so masking applies uniformly),
then combined left-to-right: UNION dedups the accumulated rows, UNION ALL
concatenates. All parts must project the same column names.
