存储过程中执行如下DDL语句
create or replace procedure etl_test(v_com varchar2) is
v_spname varchar2(40);
com varchar2(40);
begin
com := v_com;
v_spname := 'create table COM as select * from TESTUSERS where USERNAME like ''||:1||''%';
execute immediate v_spname
using in com;
end;
执行的时候报错
SQL> create or replace procedure etl_test(p_var varchar2)
2 is
3 v_spname varchar2(400);
4 begin
5 v_spname := 'create table com as select * from emp where ename like ' || chr(39) || p_var || '%' || chr(39);
6 execute immediate v_spname;
7 end;
