+insert into cust(c_city, c_first, c_last) select 'Tian Jin', 'Mars', 'Liu';
+rollback ;
+```
+
+## 选项

+### 先 commit 了
+
+```sql
+begin;
+insert into cust(c_city, c_first, c_last) select 'Tian Jin', 'Mars', 'Liu';
+commit;
+rollback ;
+```
+
+### 不必要的 end
+
+```sql
+begin;
+insert into cust(c_city, c_first, c_last) select 'Tian Jin', 'Mars', 'Liu';
+rollback ;
+end;
+```
+
+### 没有发起事务
+
+```sql
+insert into cust(c_city, c_first, c_last) select 'Tian Jin', 'Mars', 'Liu';
+rollback ;
