Data model or table summarizing equivalent key - SQL statement pairs

I would like to work on #18 and in order to do that I think I need to build a table of equivalent keys in your JSON output and their SQL equivalent. I want to start on something simple select statments with a few types of functions, aggregations, and joins. Is there any existing table showing descriptions of the equivalent SQL statements, where any related content can be found in the JSON tree?

| Key | description with example and related keys |
|- |-|
| CompoundIdentifier | tableAlias.columnName with `[0]['value'] = "tableAlias"` and `[1]['value'] = "columnName"` separated by `.` with the first portion of the identifier corresponding to a table alias found in `join.#.relation.Table.alias.name.value`

首先审阅 issue #18，并明确拟议表格的预期范围。定义它应涵盖哪些 SQL 语句、函数、聚合和 joins，然后为每个对应的 JSON 键编写文档，包含一个示例和相关键的引用；当约定的覆盖范围完整且映射经过审查后，即视为完成。
