columnsMetadata property
Optional rich metadata per column (name + protocol type
discriminant). Populated when the result came through the binary
protocol parser; remains null for results constructed from
streams that don't carry metadata or for tests/ad-hoc callers.
When non-null, has the same length as columns. See
ColumnMetadata for the discriminant table and the
ColumnMetadataTypedView extension for the OdbcType view.
Implementation
final List<ColumnMetadata>? columnsMetadata;
