Support column references that traverse into JSON/JSONB values —
data->>'x', data#>>'{a,b}', data->'a'->>'b', and the dotted data.a.b
shorthand — in SELECT column lists, WHERE filters and ORDER BY, across
the restheadspec, resolvespec, websocketspec and mqttspec handlers.
- pkg/common/json_column.go: canonical ParseColumnRef + ColumnRef.SQL()
builder. JSON path segments are bound as a single ?::text[] parameter,
never interpolated; cast targets are whitelisted via NormalizeCastTarget.
- pkg/common/json_condition.go: shared entry points mirroring
BuildSpatialCondition - ResolveJSONColumnExpr (select/sort),
BuildJSONFilterCondition (where, full operator set; infers ::numeric for
ordered comparisons on numeric values when no explicit cast is given),
and the ApplySelectColumns helper.
- pkg/reflection.IsJSONColumn / pkg/spectypes.IsJSONType: disambiguate the
dotted shorthand (data.city is JSON only when the base is a JSON column).
- pkg/common/validation.go: ColumnValidator accepts JSON tokens.
- Handlers: thread model through the filter call chains and wire the
select/sort paths.
funcspec (raw-SQL string builder, no param binding or model) and the
FetchRowNumber raw-SQL builders are left as follow-ups, as is OpenAPI
reporting of JSON sub-field columns.
Add reflection.IsEmptyValue to detect nil, empty string, and zero numbers.
Use it in recursive CUD processing to skip update/delete when the primary
key is absent, logging a warning instead of proceeding with an invalid operation.
