oracle存储过程生成编译错误

Question

这是一个简单的过程，它生成了ORA -24344编译错误和PLS - 00103.请帮助清除它们

create or replace PROCEDURE test (v_price in number)
IS
BEGIN 
    if ROWNUM = 0
        insert into admin (price) values (v_price);
    else 
        update admin set price = v_price; 
    end if;
END;

Answer 1

在条件之后忘了then：

create or replace PROCEDURE test (v_price in number) IS
rn number;
BEGIN
  select count(*) into rn from admin;
  if rn = 0 THEN
    insert into admin (price) values (v_price);
  else
    update admin set price = v_price;
  end if;
END;
