请问大侠,我要在function（）下写一个动态sql语句,如select * from A WHERE name in （‘b’,'c','d'）
但是b,c,d 是不定的,也就是我有可能传入两个参数,有可能一个参数,有可能三个参数.具体情况需要根据function得到的参数来写.请问如何写.

create or replace function test(a in varchar2,b in varchar2,c in varchar2) return is
Result ;
begin
execute immediate 'select * from A WHERE name in （'||b||','||c||','||d||'）';
return(Result);
end test;

请问大侠,我要在function（）下写一个动态sql语句,如select * from A WHERE name in SQL 语句 "SELECT * FROM {{table}} WHERE `fleet_end_time` SQL语句理解 select * from B where (select count(1) as num from A SQL语句:SELECT * from stu where name like "%伟%";的作用是:_________ SQL语句SELECT*FORM TABLE-A WHERE name LIKE‘-mation‘ 的功能? 在SQL语句中USE pubs SELECT DISTINCT title FROM title WHERE price sql如何取交集有这样两条sql语句select distinct id from a where id='123'se SQL语句什么意思主要是语句中的冒号怎么理解?如 select * from book where Author li String sql = "select * from tb_consumer where account='" + a SQL的执行顺序,如：（ Select,From,Where Group By , Order By）如何的顺序改写SQL语句,将下面这个语句改写成SELECT-FROM-WHERE的形式. sql语句中参数乘法select top 4 *from UserInfowhere ID not in(select
