如果指定 OVER 子句,则数据库确定具有最高数值优先级的参数,将其余参数隐式转换为该数据类型,并返回该数据类型。 示例 创建表 tbl1,并插入数据。 obclient> CREATE TABLE tbl1(col1 INT,col2 varchar(10),col3 INT,col4 INT); Query OK, 0 rows affected obclient> INSERT INTO tbl1 VALUES(1,'A1',...

Python pandas.DataFrame.median函数方法的使用 pandas.DataFrame.median 方法用于计算 DataFrame 中指定轴的中位数(Median)。中位数是排序后位于中间的数值,对于偶数个数据,则取中间两个数的平均值。默认计算列方向的中位数(axis=0)。skipna=True 忽略 NaN,skipna=False 不忽略 NaN。numeric_only=True 只计算数值...
