<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>
