Question

我从对表执行更新的存储过程中收到以下消息：

Procedure or function 'updateAttendee' expects parameter '@attendeeAutoID', which was not supplied.

我实际上知道为什么我会收到此错误，但我不确定我是否知道如何解决造成错误的原因。

当我分析错误的细节和堆栈跟踪时，我可以看到ColdFusion似乎正在向存储过程发送一个额外的参数。该参数是OUTPUT参数。存储过程的参数列表中没有列出输出参数。这是存储过程的代码：

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[updateAttendee] 

  @attendeeFName varchar(25)
, @attendeePreferredName varchar(25)
, @attendeeLName varchar(25)
, @attendeePhone varchar(25)
, @attendeeSecondaryPhone varchar(15) = NULL
, @attendeePrimaryEmail varchar(100)
, @attendeeSecondaryEmail varchar(100) = NULL
, @attendeeRank varchar(50)
, @attendeeTitle varchar(100)
, @attendeeOrganization varchar(100)
, @attendeeRequirements varchar(500) = NULL
, @attendeeCountryOfCitizenship varchar(50)
, @attendeeAutoID int
AS
BEGIN

SET NOCOUNT ON;

UPDATE        dbo.conferenceAttendees
SET           attendeeFName = @attendeeFName
        , attendeePreferredName = @attendeePreferredName
        , attendeeLName = @attendeeLName
        , attendeePhone = @attendeePhone
        , attendeeSecondaryPhone = @attendeeSecondaryPhone
        , attendeePrimaryEmail = @attendeePrimaryEmail
        , attendeeSecondaryEmail = @attendeeSecondaryEmail
        , attendeeRank = @attendeeRank
        , attendeeTitle = @attendeeTitle
        , attendeeOrganization = @attendeeOrganization
        , attendeeRequirements = @attendeeRequirements
        , attendeeCountryOfCitizenship = @attendeeCountryOfCitizenship

WHERE       attendeeAutoID = @attendeeAutoID

END

ColdFusion存储过程调用如下所示：

</cfstoredproc>

ColdFusion正在进行SQL调用：

{ (param 1) = call [dbo].[updateAttendee](@attendeeFName = (param 2) 
, @attendeePreferredName = (param 3) 
, @attendeeLName = (param 4) 
, @attendeePhone = (param 5) 
, @attendeeSecondaryPhone = (param 6) 
, @attendeePrimaryEmail = (param 7) 
, @attendeeSecondaryEmail = (param 8) 
, @attendeeRank = (param 9) 
, @attendeeTitle = (param 10) 
, @attendeeOrganization = (param 11) 
, @attendeeRequirements = (param 12) 
, @attendeeCountryOfCitizenship = (param 13) 
, @attendeAutoID = (param 14) )}

生成并发送到存储过程的参数如下所示：

 (param 1) = [type='OUT', sqltype='CF_SQL_INTEGER'] 
, (param 2) = [type='IN', class='java.lang.String', value='qwer', sqltype='cf_sql_varchar'] 
, (param 3) = [type='IN', class='java.lang.String', value='qwer', sqltype='cf_sql_varchar'] 
, (param 4) = [type='IN', class='java.lang.String', value='qwer', sqltype='cf_sql_varchar'] 
, (param 5) = [type='IN', class='java.lang.String', value='232-232-2323', sqltype='cf_sql_varchar'] 
, (param 6) = [type='IN', class='java.lang.String', value='', sqltype='cf_sql_varchar'] 
, (param 7) = [type='IN', class='java.lang.String', value='qwer@ewr.klk', sqltype='cf_sql_varchar'] 
, (param 8) = [type='IN', class='java.lang.String', value='', sqltype='cf_sql_varchar'] 
, (param 9) = [type='IN', class='java.lang.String', value='qwe', sqltype='cf_sql_varchar'] 
, (param 10) = [type='IN', class='java.lang.String', value='qwer', sqltype='cf_sql_varchar'] 
, (param 11) = [type='IN', class='java.lang.String', value='qwer', sqltype='cf_sql_varchar'] 
, (param 12) = [type='IN', class='java.lang.String', value='ghj', sqltype='cf_sql_varchar'] 
, (param 13) = [type='IN', class='java.lang.String', value='United States', sqltype='cf_sql_varchar'] 
, (param 14) = [type='IN', class='java.lang.Integer', value='685', sqltype='cf_sql_integer']

如您所见，Param 1是作为OUTPUT参数生成的，并导致参数列表不同步。我不是要求添加此参数。 CF中的某些东西似乎正在做这件事。当我在服务器上的SQL窗口中执行存储过程时，它可以很好地工作。

我的问题是，如何阻止CF添加此额外参数？

从评论中推广

您看到的其他输出参数是由于您在此代码行中包含并启用了returncode标记的<cfstoredproc>参数。

<cfstoredproc procedure="[dbo].[updateAttendee]" debug="yes" returncode="yes" datasource="#this.dsn#" username="#this.userName#" password="#this.password#">

添加returncode="yes" ColdFusion正在请求额外的输出变量来捕获存储过程调用的退出状态。

来自docs：

returnCode - 可选

默认值=否

说明


是：使用存储过程返回的状态代码填充cfstoredproc.statusCode。

没有

因此，您可以从<cfstoredproc>标记中删除该属性，也可以将其设置为no或保持原样，并在存储过程代码中设置正确的退出状态。

ColdFusion将不需要的输出参数添加到存储过程调用
