<cfquery></cfquery>解析后，为何多出单引号了？
<cfset strsql = "select factoryname ,vendorname from tvendor where vendorname = '上海汽车 ' ">


<cfquery name= "selecttable44 " datasource= "#application.sysdsn# ">
#strsql#
</cfquery>

debug的地方发现应用服务器吧语句变成：


"select factoryname ,vendorname from tvendor where vendorname = ' '上海汽车 ' ' "
数据库端就无法解析这个sql语句了。


难道不能动态的构造sql语句。必须写死在 <cfquery> </cfquery> 当中？




[解决办法]
使用presservesinglequotes

<cfset strsql = "select factoryname ,vendorname from tvendor where vendorname = '上海汽车 ' ">


<cfquery name= "selecttable44 " datasource= "#application.sysdsn# ">
#presservesinglequotes(strsql)#
</cfquery>
