Question

我的python UDF代码，诞生了来自Pig的日期时间变量，我尝试将它作为字符串对象，但它也给出了错误，并将其视为日期时间对象也给出了错误

Dim oval
Public Sub Worksheet_SelectionChange(ByVal Target As Range)
oval = Target.Value
End Sub

Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Range("C2:C1048576")) Is Nothing Then
Range("G" & Target.Row) = Now()
Range("H" & Target.Row) = oval
End If

End Sub

我收到错误：

TypeError：＆＃39; org.joda.time.DateTime＆＃39;对象是不可取消的

from datetime import date

@outputSchema("age_key:chararray")
def agekeyed(born):
    today = date.today()
    return born[:4]

Answer 1

born是org.joda.time.DateTime对象，此处不能应用子字符串。你需要将一个chararray从猪传递到udf，或用它的方法处理对象

rightnow.monthOfYear().getAsText()

如何将日期时间类型的变量从Pig传递给python UDF
