要使用C++進行PostgreSQL的備份和恢復,可以通過調用系統命令來執行pg_dump和pg_restore命令。以下是一個簡單的示例代碼:
備份數據庫:
#include <iostream>
#include <cstdlib>
int main() {
std::string dbName = "your_database_name";
std::string backupFile = "backup_file_path";
std::string command = "pg_dump " + dbName + " > " + backupFile;
system(command.c_str());
std::cout << "Backup completed!" << std::endl;
return 0;
}
恢復數據庫:
#include <iostream>
#include <cstdlib>
int main() {
std::string dbName = "your_database_name";
std::string backupFile = "backup_file_path";
std::string command = "psql " + dbName + " < " + backupFile;
system(command.c_str());
std::cout << "Restore completed!" << std::endl;
return 0;
}
請注意,這些代碼僅是一個簡單的示例,實際應用中可能需要添加錯誤處理和更復雜的邏輯來處理備份和恢復過程。另外,確保在執行這些命令之前,已經配置好了PostgreSQL的環境變量和用戶權限。
