文件格式,和mysql的目录结构一样:

脚本在ClickHouse文件夹下,并包含single文件夹(存储每个表的sql脚本),外面一个sys.sql 存储总的脚本、

脚本由mysql中的数据转换而来。修改规则如下:

1.修改引擎为 MergeTree ,官方主推

2.CliskHouse String类型,字符串可以是任意长度的。它可以包含任意的字节集,包含空字节。ClickHouse字符串类型可以代替其他 DBMSs 中的VARCHAR、BLOB、CLOB 等类型

3.对关键字细节定义进行了修改。替换的内容为ClikHouse 不支持的定义方式,并替换为ClickHouse支持的格式。

replaceAll(" NOT NULL", "")
.replaceAll("AUTO_INCREMENT", "")
.replaceAll("CHARACTER SET utf8mb4", "")
 .replaceAll("CHARACTER SET utf8", "")
.replaceAll("ON UPDATE CURRENT_TIMESTAMP", "")
.replaceAll("CURRENT_TIMESTAMP", "")
.replaceAll("datetime DEFAULT NULL", " DateTime ")
.replaceAll(" datetime ", " DateTime ");
.replaceAll("varchar\\(\\d+\\) DEFAULT NULL", "Nullable(String)");
.replaceAll("varchar\\(\\d+\\)", "String");
.replaceAll("text", "String");
并对bigint tinyint 类型进行了替换.替换为 ClickHouse支持的 Int8/Int16/Int32/Int64

经过导入,并测试后,没有发现问题,符合官方文档的要求。
参考官方文档:https://clickhouse.tech/docs/en/getting-started/tutorial/
