create or replace procedure TEST_TABLE is

l_table_name varchar2(50);

query_stat varchar2(100);

l_zyq t_djjcxx.zyq%type;

l_jh varchar2(20);

l_djjcxx t_djjcxx%rowtype;

begin

l_jh :='7874';

select name into l_table_name from TESTA;

DBMS_OUTPUT.put_line(l_table_name);

query_stat := 'select * from '|| l_table_name||' where jh=:l_jh';

EXECUTE IMMEDIATE query_stat into l_djjcxx using l_jh;

DBMS_OUTPUT.put_line(l_djjcxx.zyq);

end TEST_TABLE;

query_stat里面如果写成 select zyq into l_zyq from '|| l_table_name||' where jh=:l_jh' 会报错。标红的都是要注意的地方
