在数据库中，style_id列定义为CHAR（14）。我需要能够使用空格将列表中的值填充到14。我该怎么办？谢谢，

<cfset style_list = replace(#FORM.style_id#," ","","all")>

select *
from T
where 
    <cfif IsDefined("form.style_id") and form.style_id is not "">
        style_id in 
                    (
                        <cfqueryparam
                            value="#UCASE(style_list)#"
                            cfsqltype="cf_sql_varchar" 
                            list="yes" />
                    ) 
 </cfif>

使用ljustify或rjustify用空格填充字符串。

您可以使用循环对列表进行预处理：

<cfset padded_list=""/>
<cfloop list="#style_list#" item="style">
  <cfset padded_list=listappend(padded_list, rjustify(style, 14))/>
</cfloop>

如果您使用的是ColdFusion的最新版本或填充程序，则您可能还拥有listmap，这并不那么难看：

<cfset style_list=listmap(style_list, function(style) { return rjustify(style, 14); })/>

您为什么认为需要填充这些值？使用cfsqltype CF_SQL_ CHAR ，它应该可以正常工作而无需任何填充。也许是因为left side of the comparison (column) is type CHAR while the right (cfqueryparam) is type VARCHAR不能正常工作？

我测试了您的查询，它在CF 9,0,2,282541和SQL Server上运行良好。它也可以与CF 9.0.2和Oracle 12G一起正常使用。 CFQueryparam似乎可以自动处理。

DDL：

CREATE TABLE someTable(style_id char(14))
INSERT INTO someTable VALUES ('abc'),('efg          ')

CF：

<!--- worked with both CF_SQL_VARCHAR and CF_SQL_CHAR ---> 
<cfset style_list = "abc,efg">
<cfquery name="qTest" datasource="YourDSN">
    SELECT *
    FROM   SomeTable
    WHERE  style_id in 
                    (   <cfqueryparam
                            value="#UCASE(style_list)#"
                            cfsqltype="cf_sql_char" 
                            list="yes" />
                    ) 
</cfquery>
<cfdump var="#qTest#">

结果：

RESULTSET   
query
       STYLE_ID
1      abc  
2      efg
