SQL:使用子句删除重复的行

我有一个世界上所有城市的数据库

如果我运行查询，我可以看到有两个：

我已经使用此查询删除了所有重复的行：

WITH CTE AS
(
SELECT *,ROW_NUMBER() 
OVER (PARTITION BY Country, City, AccentCity, Region, Population, latitude, Longitude 
ORDER BY Country, City, AccentCity, Region, Population, latitude, Longitude) AS RN
FROM ExperimentWorld
)

DELETE FROM CTE WHERE RN<>1

现在，我将再次运行它并删除纬度和经度相同的所有列，如果两行与上图中的相同，我希望保留人口有一些值的列，并删除人口为“0”的列尝试此查询-

;WITH CTE
AS (
    SELECT *
        ,ROW_NUMBER() OVER (
            PARTITION BY Country
            ,City
            ,AccentCity
            ,Region
            ,Population
            ,latitude
            ,Longitude ORDER BY Population DESC
            ) AS RowNum
    FROM ExperimentWorld
    )
DELETE
FROM CTE
WHERE RowNum > 1

请尝试此查询-

;WITH CTE
AS (
    SELECT *
        ,ROW_NUMBER() OVER (
            PARTITION BY Country
            ,City
            ,AccentCity
            ,Region
            ,Population
            ,latitude
            ,Longitude ORDER BY Population DESC
            ) AS RowNum
    FROM ExperimentWorld
    )
DELETE
FROM CTE
WHERE RowNum > 1

添加where子句。从cte中删除，其中。。。人口<1，…添加where子句。从cte中删除，其中。。。人口<1，…是的，它起作用了，我编辑并选择了“纬度，经度”是的，它起作用了，我编辑并选择了“纬度，经度”
