我以前从数据库“监狱”读取的 JSP 文件运行良好。但是我应该将值插入数据库的“add.jsp”文件显示了这个异常:
"SQLException: Number of query values and destination fields are not the same"
My MS Access2007, converted to **Access2003** Prison db with table 'Nominal' has 14 fields:
PNo(int), PName(str), Age(int), Address(str), Height(int), Weight(int), Health(str), Possessions(str), Occupation(str), Case(str), Sentence(str), From(str), To(str) and Parole(str).
到目前为止,在 db 上使用的 sql 查询都是 select 类型。但是,更改表的查询会遇到异常。引号和逗号,名称都经过彻底检查,如其他论坛所述,但它们都很好。所以我们试图捕捉异常,但情况变得更糟。它实际上显示“添加记录”,但没有。而是在tomcat7.exe cmd 提示符中出现相同的错误消息。我使用jdk1.6.0_21这是我的代码的副本。希望有朋友帮忙:
