Android批量插入数据效率对比
1、一个一个插入
/** * 向表中插入数据 * * @param openHelper * @param appInfo * @return */ public static boolean insert(SQLiteOpenHelper openHelper, RemoteAppInfo appInfo) { if (null == appInfo) { return true; } SQLiteDatabase db = null; try { db = openHelper.getWritableDatabase(); ContentValues values = appInfo.getContentValues(); return -1 != db.insert(RemoteDBHelper.TABLE_APP_REMOTE, null, values); } catch (Exception e) { e.printStackTrace(); } finally { if (null != db) { db.close(); } } return false; } for (RemoteAppInfo remoteAppInfo : list) { RemoteDBUtil.insert(helper, remoteAppInfo); }
耗时：106524ms,也就是106s
2、 开启事务批量插入，使用
SqliteDateBase中的
insert(String table, String nullColumnHack, ContentValues values)
方法
/** * 向表中插入一串数据 * * @param openHelper * @param appInfo * @return 如果成功则返回true，否则返回flase */public static boolean insert(SQLiteOpenHelper openHelper, List<RemoteAppInfo> list) { boolean result = true; if (null == list || list.size() <= 0) { return true; } SQLiteDatabase db = null; try { db = openHelper.getWritableDatabase(); db.beginTransaction(); for (RemoteAppInfo remoteAppInfo : list) { ContentValues values = remoteAppInfo.getContentValues(); if (db.insert(RemoteDBHelper.TABLE_APP_REMOTE, null, values) < 0) { result = false; break; } } if (result) { db.setTransactionSuccessful(); } } catch (Exception e) { e.printStackTrace(); return false; } finally { try { if (null != db) { db.endTransaction(); db.close(); } } catch (Exception e) { e.printStackTrace(); } } return true;}
耗时：2968ms
3、 开启事务批量插入，使用
SQLiteStatement
/** * 第二种方式批量插入(插入1W条数据耗时：1365ms) * @param openHelper * @param list * @return */ public static boolean insertBySql(SQLiteOpenHelper openHelper, List<RemoteAppInfo> list) { if (null == openHelper || null == list || list.size() <= 0) { return false; } SQLiteDatabase db = null; try { db = openHelper.getWritableDatabase(); String sql = "insert into " + RemoteDBHelper.TABLE_APP_REMOTE + "(" + RemoteDBHelper.COL_PKG_NAME + ","// 包名 + RemoteDBHelper.COL_USER_ACCOUNT + ","// 账号 + RemoteDBHelper.COL_APP_SOURCE + ","// 来源 + RemoteDBHelper.COL_SOURCE_UNIQUE + ","// PC mac 地址 + RemoteDBHelper.COL_MOBILE_UNIQUE + ","// 手机唯一标识 + RemoteDBHelper.COL_IMEI + ","// 手机IMEI + RemoteDBHelper.COL_INSTALL_STATUS + ","// 安装状态 + RemoteDBHelper.COL_TRANSFER_RESULT + ","// 传输状态 + RemoteDBHelper.COL_REMOTE_RECORD_ID // 唯一标识 + ") " + "values(?,?,?,?,?,?,?,?,?)"; SQLiteStatement stat = db.compileStatement(sql); db.beginTransaction(); for (RemoteAppInfo remoteAppInfo : list) { stat.bindString(1, remoteAppInfo.getPkgName()); stat.bindString(2, remoteAppInfo.getAccount()); stat.bindLong(3, remoteAppInfo.getFrom()); stat.bindString(4, remoteAppInfo.getFromDeviceMd5()); stat.bindString(5, remoteAppInfo.getMoblieMd5()); stat.bindString(6, remoteAppInfo.getImei()); stat.bindLong(7, remoteAppInfo.getInstallStatus()); stat.bindLong(8, remoteAppInfo.getTransferResult()); stat.bindString(9, remoteAppInfo.getRecordId()); long result = stat.executeInsert(); if (result < 0) { return false; } } db.setTransactionSuccessful(); } catch (Exception e) { e.printStackTrace(); return false; } finally { try { if (null != db) { db.endTransaction(); db.close(); } } catch (Exception e) { e.printStackTrace(); } } return true; }
耗时：1365ms
