VB调存储过程出错
储存过程：
create proc dumpdata
as
declare @sql varchar(600)
select @sql= "dump database da1 to "E:\Data_Bak\date "+right(convert(varchar(10),getdate(),112),4)+ "" "
exec (@sql)
执行这个没问题，但在ＶＢ调用时，提示
实时错误 "-2147217900 (80040e14) ";
[Native Warning code:404101]
[DataDirect ADO Sybase Provide] backup Server:
4.41.1.1: Createing new disk file e:\data_bak\data0926
ＶＢ中调用如下：
Dim con As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim cmd As New ADODB.Command
con.Open "Provider=Sybase.ASEOLEDBProvider.2;Initial Catalog=ebook;Password=a1;User ID=user1;Data Source=ebookado;Persist Security Info=True"
Set cmd.ActiveConnection = con
cmd.CommandType = adCmdStoredProc
cmd.CommandText = "dumpdata"
cmd.Execute
为什么会有这样的错误提示？（错误提示后，存储过程仍能够执行）
