Plsql 需要修复代码，以便使用部门名称从员工中查找名字和姓氏

下面的代码用于使用部门名称从员工中查找名字和姓氏。我得到错误：错误（13,8）：PLS-00103，但我不知道如何修复它。有什么建议吗？提前谢谢

create or replace procedure xx(a in varchar2)
as
cursor b is select department_name, first_name, last_name from employees;
c employees%rowtype;
begin
open b;
loop
    fetch b into c;
    exit when b%notfound;
        if a = c.department_name then
        dbms_output.put_line(c.first_name);
        dbms_output.put_line(c.last_name);
        elseif DBMS_OUTPUT.PUT_LINE(c.last_name);
        end if;
end loop;
close b;
end;

试试下面这个：

create or replace procedure xx(a in varchar2)
as
cursor b is select department_name, first_name, last_name from employees;
c b%rowtype;
begin
open b;
loop
    fetch b into c;
    exit when b%notfound;
        if a = c.department_name then
        dbms_output.put_line(c.first_name);
        dbms_output.put_line(c.last_name);
        elseif DBMS_OUTPUT.PUT_LINE(c.last_name);
        end if;
end loop;
close b;
end;

错误（13,8）在下面的行中

elseif DBMS_OUTPUT.PUT_LINE(c.last_name);

您正在使用elsif，但没有任何条件进行测试。 如果您没有更多的条件进行比较/测试，那么最好使用else而不是elsif

create or replace procedure xx(a in varchar2)
as
cursor b is select department_name, first_name, last_name from employees;
c employees%rowtype;
begin
open b;
loop
    fetch b into c;
    exit when b%notfound;
        if a = c.department_name then
            dbms_output.put_line(c.first_name);
            dbms_output.put_line(c.last_name);
        else 
            DBMS_OUTPUT.PUT_LINE(c.last_name);
        end if;
end loop;
close b;
end;
