两个表上的BigQuery JOIN

Question

我正在尝试运行以下查询但继续遇到相同的错误

查询失败错误:在第6行第33列遇到"".期待以下之一:

查询是:

选择1_0_MEMBER_GROUP.User_Group,
1_0_MEMBER_GROUP.Member_ID,
1_4_MEMBER_TRAN_YEAR.MEMBER_UID
来自[Dataset1.1_0_MEMBER_GROUP]
JOIN [Dataset1.1_4_MEMBER_TRAN_YEAR]
ON 1_0_MEMBER_GROUP.Member_ID = 1_4_MEMBER_TRAN_YEAR.MEMBER_UID

我无法解决为什么它不会运行,必须看起来非常简单.

Answer 1

您应该使用表别名.尝试

SELECT member_group.User_Group, 
member_group.Member_ID, 
member_tran_year.MEMBER_UID 
FROM [Dataset1.1_0_MEMBER_GROUP] as member_group
JOIN [Dataset1.1_4_MEMBER_TRAN_YEAR] as member_tran_year
ON member_group.Member_ID = member_tran_year.MEMBER_UID
