如果我在SQL Server中的存儲過程與多個名爲輸入參數,全部用默認值如下:只用VBScript在ADO的命令對象中指定某些參數?
CREATE PROCEDURE [dbo].[proc_name]
(
@IN_mode CHAR(1) = NULL, /* 'I','U'*/
@IN_external_identity_id INT = -1,
@IN_provider_name VARCHAR(45) = NULL,
@IN_login_id VARCHAR(255) = NULL,
@IN_email VARCHAR(255) = NULL,
@IN_ip VARCHAR(45) = NULL,
@IN_first_name VARCHAR(255) = NULL,
@IN_last_name VARCHAR(255) = NULL,
@IN_json_response_raw VARCHAR(8000) = NULL,
@IN_user_id VARCHAR(255) = NULL,
@IN_name VARCHAR(255) = NULL
)
AS
BEGIN
...
...並在vbScript
我把這樣的過程:
Set oSproc = CreateObject("ADODB.Command")
With oSproc
.ActiveConnection = oConn
.CommandText = "bfsp_insert_NEW_EXTERNAL_IDENTITY"
.CommandType = adCmdStoredProc
With .Parameters
.Append oSproc.CreateParameter("@IN_mode", adChar, adParamInput, 1, "I")
.Append oSproc.CreateParameter("@IN_external_identity_id", adInteger, adParamInput, 0, -1) '-1 because field isn't needed on new insert
.Append oSproc.CreateParameter("@IN_provider_name", adVarChar, adParamInput, 45, "FACEBOOK")
.Append oSproc.CreateParameter("@IN_login_id", adVarChar, adParamInput, 255, getInput("fbNewUserName"))
.Append oSproc.CreateParameter("@IN_email", adVarChar, adParamInput, 255, oFbUser.email)
.Append oSproc.CreateParameter("@IN_ip", adVarChar, adParamInput, 46, getUserIp())
.Append oSproc.CreateParameter("@IN_first_name", adVarChar, adParamInput, 255, oFbUser.first_name)
.Append oSproc.CreateParameter("@IN_last_name", adVarChar, adParamInput, 255, oFbUser.last_name)
.Append oSproc.CreateParameter("@IN_json_response_raw", adVarChar, adParamInput, 8000, oFbUser.rawJson)
.Append oSproc.CreateParameter("@IN_user_id", adVarChar, adParamInput, 255, oFbUser.id)
.Append oSproc.CreateParameter("@IN_name", adVarChar, adParamInput, 255, oFbUser.name)
End With
.Execute
End With
iNewExternalIdentityId = oSproc.parameters("@OUTPUT_originalId").Value 'grabbing the new EXTERNAL_IDENTITY.ID
Set oSproc = Nothing
我注意到vbscript創建參數語句中的參數名稱並不按名稱鏈接到存儲區中的變量。它似乎根據序號位置進行匹配,例如,參數1匹配參數1,依此類推。如果我把它留在某處,那麼所有剩下的參數將被分配給存儲區中錯誤的輸入變量。
如何在vbscript代碼中創建參數,以便只發送我需要的選擇參數,並仍然使它們與過程中的參數正確匹配?
嘗試'.NamedParameters = TRUE',每https://msdn.microsoft.com/library/ms675840(聲明:不測試)。 –
否則,另一種方法是將參數添加爲無值(或爲空)而不是省略參數。 – tgolisch
