限制coldfusion中mysql显示的字符数

eli*_*reu 2 mysql coldfusion

我有一个通过Coldfusion显示的MySql数据库,查询数据库的代码是:

<cfquery name="GetWp_posts" datasource="#session.odbcname#">
SELECT  post_content
FROM    wp_posts
ORDER by ID desc
LIMIT 0, 2 </cfquery>
Run Code Online (Sandbox Code Playgroud)

显示结果的代码是:

<cfoutput query="getWp_posts">
            <cfif trim(getWp_posts.post_content) is not ""><div class = "courseShortDesc">#getWp_posts.post_content#</div></cfif>
        </cfoutput>

如何限制结果中显示的字符数量?

非常感谢
