用于搜索的存储过程在Oracle中返回错误

Question

  

可能重复：
  Searching data from a table using stored procedure in oracle by passing tablename as a parameter

此过程无法正常运行，

create or replace procedure bank_search_sp
(
p_tablename in varchar2,
p_searchname in varchar2,
p_bankcode out varchar2,
p_bankname out varchar2,
p_dist_code out number
)
as
v_tem varchar2(5000);
begin
v_tem :='select bankcode,bankname,dist_code from ' || UPPER (p_tablename) || '
where bankname like '''|| p_searchname||'';
execute immediate v_tem into p_bankcode,p_bankname,p_dist_code using p_searchname ;
commit;
end bank_search_sp;

程序正在创建，但我不知道执行时实际发生了什么。这是显示的错误..

ORA-01756: quoted string not properly terminated
ORA-06512: at "PENSIONS.BANK_SEARCH_SP", line 14
ORA-06512: at line 1

需要建议，提前谢谢。
