先安装好Starrocks，参考：Starrocks入门（二）_backend node not found. check if any backend node -CSDN博客

1、建立库

建库成功。

2、建立表

参考：表概览 | StarRocks

执行如下SQL：

CREATE TABLE user_access (uid int,name varchar(64),age int, phone varchar(16),last_access datetime,credits double
)
ORDER BY (uid, name);

报错了，报错如下：

org.jkiss.dbeaver.model.sql.DBSQLException: SQL 错误 [1064] [42000]: Table replication num should be less than or equal to the number of available BE nodes. You can change this default by setting the replication_num table properties.

3、对表的数据做添删改查
