如何處理異常並執行剩餘的語句？

Question

請找到下面的塊。

for i in 1..acd.count loop 

insert into customer_account_mapping select customerid,upper(pcd(i)),upper(acd(i)),cost from customer_master where customername=customer_name and concat(upper(pcd(i)),upper(acd(i))) not in (select concat(upper(pcode),upper(acode)) from customer_account_mapping); 

insert into user_permissions select distinct user_id,sales_person_name,sales_mgr_name,upper(pcd(i)),upper(acd(i)) from user_permissions where sales_person_name=sales_person and concat(upper(pcd(i)),upper(acd(i))) not in (select concat(upper(pcode),upper(acode)) from user_permissions) and rownum<2 ; 
commit; 
end loop; 

如果在第一個插入語句中發生錯誤，如何處理它並執行第二個插入語句。

Answer 1

EXCEPTION -- exception handlers begin 



WHEN exception type -- handles 'division by zero' error 
      ... 

WHEN OTHERS THEN -- handles all other errors 
     ROLLBACK; 

END; 

把這個代碼塊放在第一個插入語句之後。

Answer 2

纏上begin ... end ... exception它就像try/catch語句

for i in 1..acd.count loop 

begin 
    insert into customer_account_mapping select customerid,upper(pcd(i)),upper(acd(i)),cost from customer_master where customername=customer_name and concat(upper(pcd(i)),upper(acd(i))) not in (select concat(upper(pcode),upper(acode)) from customer_account_mapping); 
exception when others then 
    -- handle the exception 
end; 

insert into user_permissions select distinct user_id,sales_person_name,sales_mgr_name,upper(pcd(i)),upper(acd(i)) from user_permissions where sales_person_name=sales_person and concat(upper(pcd(i)),upper(acd(i))) not in (select concat(upper(pcode),upper(acode)) from user_permissions) and rownum<2 ; 
commit; 
end loop;
