sql - 为什么 oracle 过程无效

Question

有人可以向我解释为什么我在以下简单过程中不断收到此 PLS-00905 错误吗？谢谢。

create or replace procedure copy_table(
    table_name IN varchar2, 
    database_link IN varchar2, 
    suffix IN varchar2, 
    table_owner IN varchar2)
IS
begin
    execute immediate 'create table ' || table_name || '_' || suffix || 
    ' as select * from ' || table_owner || '.' || table_name || '@' || database_link ;
end;
/


SQL> execute myschema.copy_table;
BEGIN myschema.copy_table; END;
              *
ERROR at line 1:
ORA-06550: line 1, column 15:
PLS-00905: object myschema.copy_table is invalid
ORA-06550: line 1, column 7:
