这是什么问题?
Microsoft VBScript 编译器错误 错误 '800a03f6'
缺少 'End'
/iisHelp/common/500-100.asp,行242
Microsoft OLE DB Provider for SQL Server 错误 '80040e14'
Column 'first.name' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
我用group by 语句就出现这个问题,是什么意思啊,怎么解决?
