如果你从。net调用，你可以使用Dapper dot net:

string[] names = new string[] {"ruby","rails","scruffy","rubyonrails"};
var tags = dataContext.Query<Tags>(@"
select * from Tags 
where Name in @names
order by Count desc", new {names});

这里是达普在思考，所以你不用思考。当然，类似的事情也可能发生在LINQ to SQL中:

string[] names = new string[] {"ruby","rails","scruffy","rubyonrails"};
var tags = from tag in dataContext.Tags
           where names.Contains(tag.Name)
           orderby tag.Count descending
           select tag;

在ColdFusion中，我们只需要:

<cfset myvalues = "ruby|rails|scruffy|rubyonrails">
    <cfquery name="q">
        select * from sometable where values in <cfqueryparam value="#myvalues#" list="true">
    </cfquery>

我将传递一个表类型参数(因为它是SQL Server 2008)，并做一个where exists，或内部连接。您也可以使用XML，使用sp_xml_preparedocument，然后甚至可以索引临时表。

我有一个不需要UDF的答案，XML 因为IN接受一个选择语句 例如:SELECT * FROM Test where Data IN (SELECT Value FROM TABLE)

您实际上只需要一种将字符串转换为表的方法。

这可以通过递归CTE或使用数字表(或Master..spt_value)的查询来完成。

这是CTE的版本。

DECLARE @InputString varchar(8000) = 'ruby,rails,scruffy,rubyonrails'

SELECT @InputString = @InputString + ','

;WITH RecursiveCSV(x,y) 
AS 
(
    SELECT 
        x = SUBSTRING(@InputString,0,CHARINDEX(',',@InputString,0)),
        y = SUBSTRING(@InputString,CHARINDEX(',',@InputString,0)+1,LEN(@InputString))
    UNION ALL
    SELECT 
        x = SUBSTRING(y,0,CHARINDEX(',',y,0)),
        y = SUBSTRING(y,CHARINDEX(',',y,0)+1,LEN(y))
    FROM 
        RecursiveCSV 
    WHERE
        SUBSTRING(y,CHARINDEX(',',y,0)+1,LEN(y)) <> '' OR 
        SUBSTRING(y,0,CHARINDEX(',',y,0)) <> ''
)
SELECT
    * 
FROM 
    Tags
WHERE 
    Name IN (select x FROM RecursiveCSV)
OPTION (MAXRECURSION 32767);

也许我们可以在这里使用XML:

    declare @x xml
    set @x='<items>
    <item myvalue="29790" />
    <item myvalue="31250" />
    </items>
    ';
    With CTE AS (
         SELECT 
            x.item.value('@myvalue[1]', 'decimal') AS myvalue
        FROM @x.nodes('//items/item') AS x(item) )

    select * from YourTable where tableColumnName in (select myvalue from cte)

我们有一个函数，创建一个表变量，你可以加入:

ALTER FUNCTION [dbo].[Fn_sqllist_to_table](@list  AS VARCHAR(8000),
                                           @delim AS VARCHAR(10))
RETURNS @listTable TABLE(
  Position INT,
  Value    VARCHAR(8000))
AS
  BEGIN
      DECLARE @myPos INT

      SET @myPos = 1

      WHILE Charindex(@delim, @list) > 0
        BEGIN
            INSERT INTO @listTable
                        (Position,Value)
            VALUES     (@myPos,LEFT(@list, Charindex(@delim, @list) - 1))

            SET @myPos = @myPos + 1

            IF Charindex(@delim, @list) = Len(@list)
              INSERT INTO @listTable
                          (Position,Value)
              VALUES     (@myPos,'')

            SET @list = RIGHT(@list, Len(@list) - Charindex(@delim, @list))
        END

      IF Len(@list) > 0
        INSERT INTO @listTable
                    (Position,Value)
        VALUES     (@myPos,@list)

      RETURN
  END 

So:

@Name varchar(8000) = null // parameter for search values    

select * from Tags 
where Name in (SELECT value From fn_sqllist_to_table(@Name,',')))
order by Count desc
