Oracle 动态查询，EXECUTE IMMEDIATE select into使用方法

核心提示： create or replace procedure TEST_TABLE isl_table_name varchar2(50);query_stat varchar2(100);l_zyq t_djjcxx.zyq%type;l_jh varchar2(20);l_djjcxx t_djjcxx%rowtype

 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
