不是上面这个地址上讲的 何况它只局限于本地数据库
我说的是只用一句SQL就一切OK 而实现的功能也仅仅是将
ORACLE数据库中的表字段存入到EXCEL文件中 一般做项目的话
可以作为文档保存 打印 也便于阅读 对照
但是俺能用程序解决。。
一句SQL。俺是真的不知道。。如果真能那样太好了。。
好像SQL SERVER可以。。
select * from cat;
spool off
然后将第一列分列,只有这样了.
这并不是真正的XLS文件
select * from cat;
spool off
然后将第一列分列,只有这样了.谁说不是真正的xls,你打开看看才说,OK?
=====================================
不是，这个文件的确可以直接用EXCEL打开
但不是真正的EXCEL你打开后，再保存，此时的文件类型是用TAB的分隔的文本文件
文件名也加了引号
但是如楼主所说的，是不能用spool的
也许楼主要在应用程序执行SQL语句
是在一个ORACLE论坛上 现在怎么也找不到了
