在Access自身的幫助中看到了Create Procedure語(yǔ)句，測(cè)試了老半天，終于發(fā)現(xiàn)了訣竅：必須使用OleDb連接才能使用Create Procedure語(yǔ)句。ODBC連接不支持該語(yǔ)句，提示Create Table語(yǔ)法錯(cuò)誤。
創(chuàng)建了存儲(chǔ)過(guò)程后，使用Office Access工具打開(kāi)數(shù)據(jù)庫(kù)，在“對(duì)象 - 查詢”中能夠看到你創(chuàng)建的存儲(chǔ)過(guò)程。
創(chuàng)建存儲(chǔ)過(guò)程的語(yǔ)法：
Create Procedure YourProc
(
@param1 varchar(254),
@param2 int
)
As
(
select * from Table1 where ID>@param2 and username=@param1
)
查詢數(shù)據(jù)時(shí)只需要使用：
Rs.Open "YourProc admin,1", Conn
myproc.vbs
[復(fù)制此代碼]CODE:
Set DB = GetObject("script:http://www.zope.org/Members/Rimifon/DbHelper.sct")
DB.ConnStr = "Provider=Microsoft.Jet.OleDb.4.0;Data Source=MyProc.mdb"
DB.NonQuery "create table Sheet1(id counter,name varchar(254),score int)"
DB.NonQuery "Create Procedure MyProc(@name varchar(254), @score int) as (insert into Sheet1(name,score) values(@name, @score))"
DB.NonQuery "Create Procedure Result as (select * from Sheet1)"
MsgBox "創(chuàng)建了表和存儲(chǔ)過(guò)程"
DB.NonQuery "Execute MyProc Rimifon,90"
DB.NonQuery "Exec MyProc FengYun,93"
Set Ds = DB.DataSet("Result")
MsgBox "執(zhí)行了存儲(chǔ)過(guò)程"
DB.NonQuery "drop Procedure MyProc"
DB.NonQuery "drop Procedure Result"
DB.NonQuery "drop table Sheet1"
MsgBox "刪除了表和存儲(chǔ)過(guò)程"
Set DB = Nothing
Dim Result
Result="所有記錄：" & Chr(13)
For Each Item In Ds
If IsObject(Item) Then
Result = Result & Item.ID & Chr(9) &_
Item.Name & Chr(9) & Chr(9) &_
Item.Score & Chr(13)
End If
Next
Set Ds = Nothing
MsgBox Result風(fēng)雲(yún)數(shù)據(jù)庫(kù)操作組件
