要在PowerBuilder中可就简单了，从DataWindow导出SQL语言，执行一遍就得了，
Delphi的数据库功能实在太差，要开发数据库，还得用PB。
还是想想怎么导出SQL语句吧。

用 TBatchMove 可以复制 Table.

简单.
paradox不是一个目录吗?
拷贝目录,再Delete All;
BTW,delphi也是可以导出SQL的,大家看SQL Explore里面不就用了?
只不过我们用的比较少,大家找找肯定可以找到.

哓刚: SQL Explore不可以导出Paradox,Dbase等文件型数据库
的DDL SQL语句的.
不过 利用SQL语句的方法是比较好的方法 ! 生成表格比较简单.
生成一串Create Table 的SQL语句吧! 然后执行它!
李璋琦的办法也很好!

SQL Server有一个Script的描述,可以倒出整个数据库的结构,写成SQL.
如果找到这个函数或SQL语句就发了,呵呵

To 李璋琦:
I have tried your method, but when I excute it to this sentence:
> table2.createtable;
There is an error Coming: " Invalid parameter "
Why?

你没有设置databasename和tablename的值，也可以只设置tablename的值

TBatchMove可解决大部分捣腾数据的工作.
"要在PowerBuilder中可就简单了，从DataWindow导出SQL语言，执行一遍就得了，

说这话肯定是并不真正了解Delphi的数据库功能.
PB? 除了DataWindow外没什么特色,(我是先用PB后改用Delphi的)
PB的Bug太多了,尤其是中文方面.
PB中的数据管道就相当与TBatchMove,但速度奇慢.
哥们,过来吧,别用那玩艺了!

使用database desktop,首先用Utility中的copy功能拷贝数据表；
其次，使用utility中的Empty功能清空数据表即可！

To 李璋琦:
I already set them. But the problem exists yet! I reallydo
n't know
why.
To 曹晓钢 and DeckYou:
I want todo
this in program. In fact, Ido
n't want the user todo
this by hand.
To SeaSky:
This is a good way, but Ido
n't write the SQL sentence again. I want
to use the existed database.
Thank all of you and long your help!

请看下面代码:
procedure TForm1.Button1Click(Sender: TObject);
begin
table2.tablename:='c:/create.db';
Table2.fielddefs:=table1.fielddefs;
table2.indexdefs.assign(table1.indexdefs);
table2.createtable;
end;
procedure TForm1.FormCreate(Sender: TObject);
begin
Table1.databasename:='DBDEMOS';
Table1.Tablename:='customer.db';
Table1.open;
end;
如果还不行,把你的原码maileto:delphi4@263.net
procedure TForm1.Button1Click(Sender: TObject);
begin
table2.tablename:='c:/create.db';
Table2.fielddefs:=table1.fielddefs;
table2.indexdefs.assign(table1.indexdefs);
table2.createtable;
end;
procedure TForm1.FormCreate(Sender: TObject);
begin
Table1.databasename:='DBDEMOS';
Table1.Tablename:='customer.db';
Table1.open;
end;
