Question

我希望在MySQL的前n行中从表中得到min（somecolumn）。获得结果的最佳查询是什么？

到目前为止我找到了

Dim files = Directory.GetFiles("C:\path", "*.*", SearchOption.AllDirectories)
       .Where(Function(s) s.EndsWith(".mp4", StringComparison.OrdinalIgnoreCase)     
       OrElse s.EndsWith(".wmv", StringComparison.OrdinalIgnoreCase))

Answer 1

select min(t.columnName) from tableName as t limit 10（此处n限制为前10行为例）

OR

select outerTable.columnName from (select distinct t.columnName from tableName as t order by t.columnName asc limit 10) as outerTable limit 1,1

Answer 2

尝试以下语法：

SELECT min(columname) FROM tablename limit n

获得前n行的最小值
