传入实体执行(可添加 修改 删除)事务。

IDbHelper dbHelper = new OracleHelper(ConfigHelper.GetConfigString("BusinessDbConnection")); bool result = true; try { dbHelper.BeginTransaction(); //主表 TE_AREAManager manager = new TE_AREAManager(dbHelper, userInfo); TE_AREAEntity tE_AREAEntity = manager.GetObject(dbHelper.SqlSafe(eatxtAREA_ID)); manager.Delete(tE_AREAEntity); //子表 TE_AREA_SUBManager submanager = new TE_AREA_SUBManager(dbHelper, userInfo); TE_AREA_SUBEntity tE_AREA_SUBEntity = submanager.GetObject(dbHelper.SqlSafe(eatxtAREA_ID)); submanager.Delete(tE_AREA_SUBEntity); //事务提交  dbHelper.CommitTransaction(); } catch(Exception ex) { //事务回滚 dbHelper.RollbackTransaction(); result=false; } 可以传入sql语句执行事务 IDbHelper dbHelper = new OracleHelper(ConfigHelper.GetConfigString("BusinessDbConnection")); bool result = true; try { dbHelper.BeginTransaction(); string commandText = " DELETE FROM TE_AREA WHERE ID=" + dbHelper.SqlSafe(id); dbHelper.ExecuteNonQuery(sqlString); commandText = " DELETE FROM TE_AREA_SUB WHERE ID=" + dbHelper.SqlSafe(id); dbHelper.ExecuteNonQuery(commandText); dbHelper.CommitTransaction(); } catch(Exception ex) { dbHelper.RollbackTransaction(); result=false; } 还可以同时传入实体,SQL语句 IDbHelper dbHelper = new OracleHelper(ConfigHelper.GetConfigString("BusinessDbConnection")); bool result = true; try { dbHelper.BeginTransaction();               //主表 TE_AREAManager manager = new TE_AREAManager(dbHelper, userInfo); TE_AREAEntity tE_AREAEntity = manager.GetObject(dbHelper.SqlSafe(eatxtAREA_ID)); manager.Delete(tE_AREAEntity);               //子表 TE_AREA_SUBManager submanager = new TE_AREA_SUBManager(dbHelper, userInfo); TE_AREA_SUBEntity tE_AREA_SUBEntity = submanager.GetObject(dbHelper.SqlSafe(eatxtAREA_ID)); submanager.Delete(tE_AREA_SUBEntity);                              //执行SQL语句               string commandText = " DELETE FROM JINTIANDA WHERE ID=" + dbHelper.SqlSafe(id);               dbHelper.ExecuteNonQuery(commandText);               //事务提交  dbHelper.CommitTransaction(); } catch(Exception ex) {              //事务回滚 dbHelper.RollbackTransaction(); result=false; }
