如果第一个记录异常发生，第二个记录不会执行什么操作？

Question

DECLARE 
    ERROR_COUNT NUMBER; 
    errno number; 
    e_msg varchar2(50); 
    e_idx varchar2(20); 

    TYPE emp_type IS TABLE OF emp_source%ROWTYPE; 
    EMP_VAR emp_type; 

    CURSOR c1 IS SELECT * FROM emp_source; 

BEGIN 
    OPEN c1; 

    loop 
     FETCH c1 BULK COLLECT INTO EMP_VAR; 

     BEGIN 
      FORALL i in 1 .. EMP_VAR.COUNT save exceptions  
      insert INTO emp_target (e_id,e_name,sal) values (EMP_VAR(i).E_ID,EMP_VAR(i).E_NAME,EMP_VAR(i).SAL); 

      FORALL i in 1 .. EMP_VAR.COUNT save exceptions  
      insert INTO department_target (dep_name) values (EMP_VAR(i).dep_name); 

     EXCEPTION 
      WHEN others THEN 
       ERROR_COUNT := sql%bulk_exceptions.count; 

       for i in 1 .. ERROR_COUNT 
       loop 
        errno := sql%bulk_exceptions(i).error_code; 
        e_msg := sqlerrm(-errno); 
        e_idx := sql%bulk_exceptions(i).error_index; 

        insert into emp_save_exc values(errno,e_msg,e_idx); 
       end loop; 
     END; 
     exit when c1%notfound; 
    end loop; 

    close c1; 
    commit; 
END;

你可以把周围的第一FORALL一个BEGIN/END块和处理这样的例外：

BEGIN 
    FORALL i in 1 .. EMP_VAR.COUNT save exceptions  
    insert INTO emp_target (e_id,e_name,sal) values (EMP_VAR(i).E_ID,EMP_VAR(i).E_NAME,EMP_VAR(i).SAL); 
EXCEPTION 
    WHEN ... 
END; 

你也可以把每个块成一个程序，让你的代码更有条理：

DECLARE 
    ... 
    PROCEDURE insert_emp_target (p_emp_var emp_type) IS 
    BEGIN 
     FORALL i in 1 .. EMP_VAR.COUNT save exceptions  
      insert INTO emp_target (e_id,e_name,sal) 
       values (EMP_VAR(i).E_ID,EMP_VAR(i).E_NAME,EMP_VAR(i).SAL); 
    EXCEPTION 
     WHEN ... 
    END; 

    PROCEDURE insert_dept_target (p_emp_var emp_type) IS 
    ... 
BEGIN 
    OPEN c1; 
    loop 
     FETCH c1 BULK COLLECT INTO EMP_VAR; 
     exit when c1%notfound; 
     insert_emp_target (emp_var); 
     insert_dept_target (emp_var); 
     ... 
    end loop; 
    close c1; 
    commit;  
END;
