最近发布的 Elasticsearch 6.3 包含了大家期待已久的 SQL 特性，今天给大家介绍一下具体的使用方法。 首先看看接口的支持情况 目前支持的 SQL 只能进行数据的查询只读操作，不能进行数据的修改，所以我们的数据插入还是要走之前的常规索引接口。 目前 Elasticsearch 的支持 SQL 命令只有以下几个： 命令 说明 DESC table 用来描述索引的字段属性 SHOW COLUMNS 功能同上，只是别名 SHOW FUNCTIONS 列出支持的函数列表，支持通配符？过滤 SHOW TABLES 返回索引列表 SELECT .. FROM table_name WHERE .. GROUP BY .. HAVING .. ORDER BY .. LIMIT .. 用来执行查询的命令 我们分别来看一下各自怎么用，以及有什么效果吧，自己也可以动手试一下，看看。 首先，我们创建一条数据： POST twitter/doc/ { "name":"medcl", "twitter":"sql is awesome", "date":"2018-07-27", "id":123 } RESTful下调用SQL 在 ES 里面执行 SQL 语句，有三种方式，第一种是 RESTful 方式，第二种是 SQL-CLI 命令行工具，第三种是通过 JDBC 来连接 ES，执行的
