将整数列表传递给存储过程

Pass List of Integers to Stored Procedure

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,我可以这样执行成功:

exec dbo.Dan '1.2' 

在 ColdFusion 中,我可以使用这两组命令中的任何一个成功地执行它:

<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对此进行改进。由于 cfprocparam 没有列表属性,我认为我仅限于 cfquery 方法。到目前为止,我的努力和结果是:

<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,但这似乎有点麻烦。有没有办法将整数列表作为整数列表传递?

正如之前提到的其他评论者,传递 table 值参数是可行的方法。这将要求您更改 SP 中的输入以采用 table 输入,并且在您的查询中您可以执行

<cfquery>
    CREATE TABLE @temp (usedID int)
    INSERT INTO @temp 
        (usedID)
        VALUES
        (1)
        ,(2)

    exec dbo.Dan @temp
</cfquery>

您可能需要更改将参数传递给 SP 的方式,但这是一般的想法。

rodmunera 的回答大体思路正确。这是我最终让它工作的方法。

在 sql 服务器中,我是这样开始的:

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

然后我通过存储过程改成了这样:

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 代码是这样的:

<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#">
