将存储过程的整数传递列表 [英] Pass List of Integers to Stored Procedure

问题描述

这是我的存储过程：

ALTER PROCEDURE [dbo].[Dan] 
@numbers varchar(10)    
AS
BEGIN
SET NOCOUNT ON;
select @numbers numbers
END

在SSMS中，我可以成功执行像这样：

In SSMS, I can execute it successfully like this:

exec dbo.Dan '1.2' 

在ColdFusion中，我可以使用以下两组命令之一成功执行它：

In ColdFusion, I can execute it successfully with either of these two sets of commands:

<cfstoredproc procedure="dbo.dan" datasource="ClinicalDataDev">
<cfprocparam cfsqltype="cf_sql_varchar" value="1,2"> 
<cfprocresult name="abc">
</cfstoredproc>

<cfquery name="abcd" datasource="ClinicalDataDev">
exec dbo.Dan <cfqueryparam cfsqltype="cf_sql_varchar" value='1,2' list="no">
</cfquery>

但是，我希望通过将值指定为整数列表来改进。由于cfprocparam没有列表属性，我认为我仅限于cfquery方法。我的努力和结果到目前为：

However, I'm looking to improve on this by specifying the value as a list of integers. Since cfprocparam does not have a list attribute, I think I am restricted to the cfquery approach. My efforts and results so far are:

<cfqueryparam cfsqltype="cf_sql_integer" value='1' list="no">
executes successfully.  The purpose is to see if the procedure accepts an 
integer - it does.

<cfqueryparam cfsqltype="cf_sql_integer" value='1,2' list="no">
also executes sucessfully, but returns a value of 42006.  Probably not 
worth persuing.

<cfqueryparam cfsqltype="cf_sql_integer" value='1,2' list="yes">
throws an error for two many paramters.  
The same thing happens with cf_sql_varchar.

如前所述，我可以将列表作为字符串传递，但看起来像一个黑客。有没有办法将整数列表作为整数列表传递？

As stated earlier, I can pass the list as a string, but that seems like a bit of a hack. Is there a way to pass the list of integers as a list of integers?

推荐答案

rodmunera的答案有正确的一般想法。

rodmunera's answer has the correct general idea. Here is how I finally got it to work.

在sql server中，我开始使用：

In sql server, I started with this:

CREATE  TYPE pt.IntegerTableType AS TABLE 
( integerIN int);
grant execute on type::pt.IntegerTableType to theAppropriateRole

到此：

ALTER PROCEDURE [dbo].[Dan] 
@numbers pt.IntegerTableType readonly
AS
BEGIN
SET NOCOUNT ON;
select 1 record 
where 1 in (select integerIN from @numbers) 
END

Coldfusion代码是这样：

The Coldfusion code is this:

<cfset numbers = "1,2">
<cfquery name="abcd" datasource="ClinicalDataDev">
declare @dan as pt.IntegerTableType

insert into @dan
select null 
where 1 = 2
<cfloop list="#numbers#" index="number">
union
select <cfqueryparam cfsqltype="cf_sql_integer" value="#number#">
</cfloop>

exec dbo.Dan @dan
</cfquery>
<cfdump var="#abcd#">
