Review comment:
hi @zhztheplayer Sorry for the late reply. `JSON_LENGTH(json_doc[, path])`
calcite is semantically supported. I hope you can help me. I don't quite
understand the implementation of `JsonApiCommonSyntax()`, but my idea is to
take this `JsonApiCommonSyntax()` and tweak it to take care of the
`JSON_LENGTH` syntax.
best
