SQLite提供了两种备份和恢复数据库的方法:使用SQLite命令行工具和使用SQLite的API。
备份数据库:
sqlite3 original.db .dump > backup.sql
恢复数据库:
sqlite3 new.db < backup.sql
备份数据库:
sqlite3 *db;
sqlite3_backup *backup;
sqlite3_open("original.db", &db);
sqlite3_open("backup.db", &backup);
sqlite3_backup_init(backup, "main", db, "main");
while ((rc = sqlite3_backup_step(backup, -1)) == SQLITE_OK) {}
sqlite3_backup_finish(backup);
恢复数据库:
sqlite3_backup *backup;
sqlite3 *db;
sqlite3_open("backup.db", &db);
sqlite3_open("original.db", &backup);
sqlite3_backup_init(backup, "main", db, "main");
while ((rc = sqlite3_backup_step(backup, -1)) == SQLITE_OK) {}
sqlite3_backup_finish(backup);
以上是使用SQLite进行备份和恢复数据库的方法,具体操作可以根据实际需求进行调整。
