谁能帮我看看这错在哪了。？

sql = "insert into base (xuelei,xuewei,leavetime,zhuanye," _
& "xuezhi,biyeschool,biye_type,zhiwu_dif,fazheng,gettime,zhiwu_name,gettype)" _
& "values(" & xuelei & "," & xuewei & "," & leavetime & "," & zhuanye & "," & xuezhi & "," _
& " " & biyeschool & "," & biye_type & "," & zhiwu_dif & "," & fazheng & "," & gettime & "," _
& " " & zhiwu_name & "," & gettype & ")"
gcn.Execute (sql)　　＜－－－－
我在编译时，也没出现错误提示啊。但一运行时到gcn.Execute (sql)时，停止了。提示
insert into 语句的语法错误
我实在找不出来错误了。
高手赐教！

上面的不对。下面的是原文。大家帮小弟我看看吧
sql = "insert into base (xuelei,xuewei,leavetime,zhuanye," _
& "xuezhi,biyeschool,biye_type,zhiwu_dif,"_
& "fazheng,gettime,zhiwu_name,gettype)" _
& "values(" & xuelei & "," & xuewei & "," & leavetime & "," _
& " " & zhuanye & "," & xuezhi & "," _
& " " & biyeschool & "," & biye_type & "," & zhiwu_dif & "," _
& " " & fazheng & "," & gettime & "," _

有可能出现的错误：
1、插入的值与数据库表中的数据类型不匹配
2、插入的值可能为null，而数据库表中的字段不能为null
3、插入的值为12个，数据库表中字段数量是不是有12个
