我的带有select的SQL存储过程只返回没有值的表，它只显示没有任何值的列名吗？为什么？如何使用存储过程检索表的值？

end
if(@mode =2) 
begin
select * from UserRegister 
end
if (@mode =3) 
begin
update UserRegister  set name=@name,usertype=@usertype,password=@password ,email=@email,mob=@mob where username=@username
end
if(@mode =4) 
begin
delete from UserRegister where username=@username
end
if(@mode =5) 
begin
  select * from UserRegister where username =@username and password =@password 
  end
if(@mode =6) 
begin
  select * from UserRegister where usertype= @usertype
  end
  if(@mode =7) 
begin
  select * from UserRegister where usertype  =@usertype  and username =@username 
  end
end

Answer 1

1）尝试运行

select * from UserRegister 确保表格有数据

如果数据存在

2）你应该尝试用
运行 select * from UserRegister where usertype ='abc' and username ='abc'

abc 是来自UserRegister表的实际数据

SQL存储过程选择仅返回没有值的表
