-Kylin 是使用 Calcite 进行查询的，原则上 Kylin 支持所有 Calcite 能够识别的语句。
+Apache Kylin 使用 Apache Calcite 做 SQL 解析和优化。作为一款 OLAP 引擎, Kylin 支持 `SELECT`
操作，而不支持其它操作例如 `INSERT`，`UPDATE` 和 `DELETE`，因此 Kylin 的 SQL 语法是 Apache Calcite
支持语法的一个子集。本文列举了 Kylin 支持的 SQL 语法、函数以及数据类型，但可能并不完整。您可以查看 [Calcite SQL
reference](https://calcite.apache.org/docs/reference.html) 以了解更多内容。

-Kylin uses Calcite for the query. In principle, Kylin supports all statements
that Calcite recognizes.
+Apache Kylin relies on Apache Calcite to parse and optimize the SQL
statements. As an OLAP engine, Kylin supports `SELECT` statements, while
doesn't support others like `INSERT`, `UPDATE` and `DELETE` operations in SQL,
so Kylin's SQL grammer is a subset of Apache Calcite. This page lists the SQL
grammar, the functions and the basic data types that Kylin supports. You can
also check [Calcite SQL
reference](https://calcite.apache.org/docs/reference.html) for more detailed
info.
