oracle错误输出,oracle – SQL小提琴输出错误

实际上我是PL / sql的新手

我在sql Fiddle中使用oracle pl / sql创建了下表

create table Employee(name varchar2(100),id integer,salary integer,PRIMARY KEY(id));

insert into Employee(name,id,salary) values('sa',94,100);

insert into Employee(name,salary) values('pr',88,150);

insert into Employee(name,salary) values('ji',33,900);

insert into Employee(name,salary) values('na',24,880);

insert into Employee(name,salary) values('po',65,770);

insert into Employee(name,salary) values('ri',69,910);

insert into Employee(name,salary) values('uj',12,650);

insert into Employee(name,salary) values('ad',43,440);

insert into Employee(name,salary) values('sam',40,550);

我执行了以下查询

DECLARE

employee_record Employee%ROWTYPE;

BEGIN

select * into employee_record from Employee where id>90;

dbms_output.put_line(employee_record.name||' '||employee_record.id||' '||employee_record.salary);

END;

/

我得到以下输出

Record Count: 0; Execution Time: 2ms

它应该打印员工记录中的值,对吧？我的SQL查询中有什么问题或sql小提琴无法显示dbms_output的一些问题？
