Kylin 给出的列 'STATE_NAME' 在任何表中都找不到

Question

我按照 kylin 教程，成功创建了 kylin 模型和 kylin cube。Kylin cube 构建也成功完成。 我创建了一个事实表，

create table sales_fact(product_id int,state_id int,location_id string,sales_count int)
row format delimited
fields terminated by ','
lines terminated by '\n'
stored as textfile;


create table state_details(state_id int,state_name string)
    row format delimited
    fields terminated by ','
    lines terminated by '\n'
    stored as textfile;

我将这些表加载为， 事实表

1000,1,AP1,50
1000,2,KA1,100
1001,2,KA1,50
1002,1,AP1,50
1003,3,TL1,100

state_details

1,AP
2,Karnataka
3,Telangana
4,kerala

但如果我查询简单查询为，

select sales_count from sales_fact where state_name="Karnataka";

错误如下：

Error while executing SQL "select sales_count from sales_fact where state_name="Karnataka" LIMIT 50000": From line 1, column 42 to line 1, column 51: Column 'STATE_NAME' not found in any table

我找不到原因。任何人有任何想法请告诉我。

Answer 1

state_name 不在 sales_fact 表上，请尝试：

select sales_count from sales_fact as f inner join state_details as d on f.state_id = d.state_id where d.state_name='Karnataka';
