傳遞參數到存儲過程中經典的asp

Question

我以前曾問過類似的問題，雖然我試圖解決我以前的代碼，但現在我得到了一個錯誤「參數是錯誤的類型，超出了可接受的範圍，或相互衝突「。我想傳遞一個字符作爲參數來查詢數據庫，然後使用記錄集打印出一個網頁。我的經典ASP代碼低於

Set objCon = CreateObject("ADODB.Connection") 
Set objRS = CreateObject("ADODB.Recordset") 
set objComm = CreateObject("ADODB.Command") 

objCon.ConnectionString = "Provider=SQLOLEDB.1;Password=xxxx;Persist Security Info=True;User ID=xxxx;Initial Catalog=Movies;Data Source=xxxx-PC" 
objCon.open objCon.ConnectionString 

objComm.ActiveConnection = objCon.ConnectionString 
objComm.CommandText = "Paging_Movies" 
objComm.CommandType = adCmdStoredProc 

Set objParameter = objComm.CreateParameter 
objParameter.Name = "alphaChar" 
objParameter.Type = adChar 
objParameter.Direction = adParamInput 
objParameter.Value = "a" 

objComm.Parameters.Append objParameter 

set objRs = objComm.Execute 

而且我的存儲過程是如下 -

CREATE PROCEDURE Paging_Movies 
@alphaChar char(1) 
AS 
if @alphaChar = '#' 
    select * from Movies where movies like '[^a-z]%' 
else 
    select * from Movies where movies like @alphaChar + '%' 

Answer 1

也許你要添加的參數兩次。嘗試更換：

objComm.ActiveConnection = objCon.ConnectionString 
objComm.CommandText = "Paging_Movies" 
objComm.CommandType = adCmdStoredProc 

Set objParameter = objComm.CreateParameter 
objParameter.Name = "alphaChar" 
objParameter.Type = adChar 
objParameter.Direction = adParamInput 
objParameter.Value = "a" 

Set objParameter = objCommand.CreateParameter ("alphaChar", adChar, _ 
    adParamInput, "a") 

objComm.Parameters.Append objParameter 

只：

objCommand.CreateParameter ("alphaChar", 129, 1, 1, "a") 

編輯爲您的意見建議（1）從W3Schools CreateParameter page使用的數值爲adChar（129）和adParamInput。
