SELECT imps.Interest_name as PopularInterests,
imps.SUM(Count) AS Total_Count,
ints.Vertical_Name
FROM Impressions imps
INNER JOIN Interests ints ON imps.Interest_name = ints.Interest_name
GROUP BY imps.Interest_name
HAVING imps.SUM(Count) > 10000;
查询给出了错误:
查找错误 - SQL Server数据库错误:找不到任一列 “imps”或用户定义的函数或聚合“imps.SUM”,或者 名字含糊不清
我的表格如下:
曝光:
Interest_Name Count
Geo_934293 1107
Geo_934293 852
Geo_934293 934
Geo_8133957 1810
Geo_8133957 909
Geo_8133957 463
Geo_8133957 736
Geo_8133957 7000
垂直行业:
Interest_Name Vertical_Name
Geo_934293 X
Geo_8133957 Y
预期结果将是:
Popular_Interest Total_Count Vertical_Name
Geo_8133957 10918 Y
不确定我哪里错了?我认为它与SUM
函数有关。
答案 0 :(得分:2)
您需要使用SUM(imps.Count)
代替imps.SUM(Count)
(语法无效):
SELECT
imps.Interest_name as PopularInterests,
SUM(imps.Count) AS Total_Count,
ints.Vertical_Name
FROM Impressions imps
INNER JOIN Interests ints ON imps.Interest_name = ints.Interest_name
GROUP BY imps.Interest_name, ints.Vertical_Name
HAVING SUM(imps.Count) > 10000;
