SQL查询不是谷歌的BigQuery

Question

工作当我尝试在谷歌的BigQuery此查询，我得到以下错误：

"SELECT query which references non constant fields or uses aggregation functions or has one or more of WHERE, OMIT IF, GROUP 
BY, ORDER BY clauses must have FROM clause." 

这是怎么回事？

SELECT fq.ds_id AS ds_id, 
     fq.dm_id AS dm_id, 
     fq.freq AS freq, 
     rc.rec AS rec, 
     rd.reg AS reg 
FROM dataset.table_fq_ds fq 
    INNER JOIN EACH dataset.table_rc_ds rc ON (fq.ds_id = rc.ds_id) 
    INNER JOIN EACH dataset.table_rd_ds rd ON (fq.ds_id = rd.ds_id);

我希望下面将有助于排除故障

首先选择完美的作品，而第二个给了完全相同的错误

“正确” 版本

SELECT 
    fq.ds_id AS ds_id, 
    fq.dm_id AS dm_id, 
    fq.freq AS freq, 
    rc.rec AS rec, 
    rd.reg AS reg 
FROM (SELECT 1 AS ds_id, 11 AS dm_id, 12 AS freq) fq 
INNER JOIN EACH (SELECT 1 AS ds_id, 22 AS rec) rc ON (fq.ds_id = rc.ds_id) 
INNER JOIN EACH (SELECT 1 AS ds_id, 33 AS reg) rd ON (fq.ds_id = rd.ds_id); 

ds_id dm_id freq rec reg 
    1  11  12  22 33 

，错误版本 - 只有第一个INNER：
SELECT ds_id VS SELECT 1 AS ds_id

SELECT 
    fq.ds_id AS ds_id, 
    fq.dm_id AS dm_id, 
    fq.freq AS freq, 
    rc.rec AS rec, 
    rd.reg AS reg 
FROM (SELECT 1 AS ds_id, 11 AS dm_id, 12 AS freq) fq 
INNER JOIN EACH (SELECT ds_id, 22 AS rec) rc ON (fq.ds_id = rc.ds_id) 
INNER JOIN EACH (SELECT 1 AS ds_id, 33 AS reg) rd ON (fq.ds_id = rd.ds_id); 

Error: SELECT query which references non constant fields or uses aggregation functions or has one or more of WHERE, OMIT IF, GROUP BY, ORDER BY clauses must have FROM clause.
