我遵循了kylin教程,能够成功创建kylin模型和kylin cube.Kylin cube build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;
我把这些表加载为, fact_table
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,
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
我无法找到原因。任何人都有任何想法请告诉我。
答案 0 :(得分:0)
state_name
不在表sales_fact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';
