非常复杂,不仔细介绍,此时需要将20120801处全部变成参数传入,,只写参数就得累死我,下面方法可以节省我的好多工作量,在最内部函数中修改select
b.scode,b.fund5,b.fund4,b.fund10,20120801 tdate
from
将20120801用tdate变量来代替,这样传入的参数就用tdate来表示就可以了。

非常复杂,不仔细介绍,此时需要将20120801处全部变成参数传入,,只写参数就得累死我,下面方法可以节省我的好多工作量,在最内部函数中修改select
b.scode,b.fund5,b.fund4,b.fund10,20120801 tdate
from
将20120801用tdate变量来代替,这样传入的参数就用tdate来表示就可以了。
