SQL导DBF文件

从SQL导出没有存在的DBF文件中。。

我在邹建贴子里找到了方法。。

但他里面没有写，当SQL是numeric(18, 3) 要怎么写啊。。。

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

ALTER proc [dbo].[p_exporttb]
--@sqlstr varchar(8000), --要导出的查询名
--@path nvarchar(1000), --文件存放目录
--@fname nvarchar(250)='temp.dbf',--文件名,默认为temp
--@over bit=0 --是否覆盖已经存在的文件,如果不覆盖,则直接追加
as

set @over =1
set @path ='d:\'

else
set @vDay=datename(day,getdate())
