“错误号:3704 错误描述:对象关闭时,不允许操作。sql=select top 10 ContentID,a.SortID,a.GroupID,a.Exc.......”
inc/AspCms_MainClass.asp文件,大约900行,原来代码为:
复制代码代码如下:
if str="content" or str="news" or str="product" or str="down" or str="pic" then
sperStrs =conn.Exec("select SpecCategory+'_'+SpecField from {prefix}SpecSet Order by SpecOrder Asc,SpecID", "arr")
if isarray(sperStrs) then
for each spec in sperStrs
sperStr = sperStr&","&spec
next
end if
我们修改为:
复制代码代码如下:
if str="content" or str="news" or str="product" or str="down" or str="pic" then
sperStrs =conn.Exec("select SpecCategory+'_'+SpecField from {prefix}SpecSet Order by SpecOrder Asc,SpecID", "arr")
if isarray(sperStrs) then
sperStr=""
for each spec in sperStrs
sperStr = sperStr&","&spec
next
end if
因为程序在同一个页面循环{aspcms:content}标签时,原来的代码在后面再调用该标签时会不断累加 sperStr值,造成该标签数量越多,后面的SQL查询字段,而Access数据库,单表最多255个字段,SQL查询里面一次查询也最多不超过255个字段,当累加的字段数超过255个时,运行程序就会出错。此时,会引起inc/AspCms_MainClass.asp文件,大约152行的程序代码,内容是:
复制代码代码如下:
If Not DebugMode Then
if Err then
errid=Err.number:errdes=Err.description:Err.Clear:dbConn.close:set dbConn=nothing:isConnect=false
echoErr err_03,errid,errdes&"sql="&sqlStr
end if
end if
如果有错误,程序代码会关闭数据。于是就出现了前文的错误 。
