如何使用SQL备份数据库?

[dbcontrols]

'* * * * * * * * * * * * * *
'Passing Values
'* * * * * * * * * * * * * *
'nServer_Name = SQL server name
'nDB_Name = Database name
'nDB_Login = Login name
'nDB_Password = Password
'nBack_Dev =Backup device name
'nBack_Set = Backup set name
'nBack_Desc = Backup discription

'Backup device name has to be specified by the SQL ADMIN.
'Which comes under SQL Backup. The name you specified must
'be same as Passing value of backup device name.

'SQL ADMIN can only specify the device type(Tape, HD,...).

要安装SQL的客户端才可以.

执行SQL语句backup,具体格式忘记了，你自己查查看吧

同意dbcontrols(泰山)　

[sha_boy]

to:dbcontrols(泰山)
我的意思是:在VB中使用SQL语句,　 而不是在SQLServer中!
请各位大侠伸手相助!

[westwin]

dim cn as adodc.connection
cn.execute strsql

[dbcontrols]

这就是在VB中,需要安装SQL的客户端才能得到那几个DLL.笨!

use master
EXEC sp_addumpdevice 'disk', 'dev_test','c:\test.dat'
backup database test to dev_test
