概述：

1.连接：

2.设置驱动：

 

版本查询：

https://mvnrepository.com/artifact/ru.yandex.clickhouse/clickhouse-jdbc

驱动设置好之后需要下载,会使用Maven自动下载依赖的jar包,相关的依赖下载需要保持网络的畅通，下载需要等待一段时间

3.测试连接：

 

4.登陆测试SQL：

 

Clickhouse中总的大小：
select
    sum(rows) as "rows",
    formatReadableSize(sum(data_uncompressed_bytes)) as "data_size",
    formatReadableSize(sum(data_compressed_bytes)) as "compress_size",
    round(sum(data_compressed_bytes) / sum(data_uncompressed_bytes), 4) "compress_ratio"
from system.parts;

查询某个表的行数，大小，压缩比：

select
   p.`table` ,
    sum(rows) as "rows",
    formatReadableSize(sum(data_uncompressed_bytes)) as "data_size",
    formatReadableSize(sum(data_compressed_bytes)) as "compress_size",
    round(sum(data_compressed_bytes) / sum(data_uncompressed_bytes), 4) "compress_ratio"
from system.parts p
where table in('ontime')        
group by p.table;
