如何实现远程调用ACCESS数据库
如果要导出 SQL Server 数据库,可以使用 `sqlcmd` 命令行工具,具体步骤如下:
1. 导入必要的库:
```python
import os
import subprocess
```
2. 构造导出命令:
```python
command = f"sqlcmd -S {host} -U {username} -P {password} -d {database} -Q \"BACKUP DATABASE [{database}] TO DISK='{export_folder}/{database}.bak'\""
```
3. 执行导出命令:
```python
try:
subprocess.check_call(command, shell=True)
print(f"{database} database exported successfully to {export_folder}")
except subprocess.CalledProcessError as e:
print(f"Failed to export {database} database: {e}")
```
完整的方法如下:
```python
import os
import subprocess
def export_remote_database(host, username, password, database, export_folder):
command = f"sqlcmd -S {host} -U {username} -P {password} -d {database} -Q \"BACKUP DATABASE [{database}] TO DISK='{export_folder}/{database}.bak'\""
try:
subprocess.check_call(command, shell=True)
print(f"{database} database exported successfully to {export_folder}")
except subprocess.CalledProcessError as e:
print(f"Failed to export {database} database: {e}")
```
这个方法可以将指定的远程 SQL Server 数据库导出为一个 BAK 文件,并保存到本地指定的文件夹中。
