Oracle随机创建表并删除

1、代码:

DECLARE
  v_sql        VARCHAR2(100) := 'create table t(id varchar2(100))';
  v_id         VARCHAR2(100);
  v_table_name VARCHAR2(30) := dbms_random.string('l', 10);
BEGIN
  NULL;
  v_sql := 'create table ' || v_table_name || '(id varchar2(100))';
  dbms_output.put_line(v_table_name);
  EXECUTE IMMEDIATE v_sql;
  EXECUTE IMMEDIATE 'INSERT INTO ' || v_table_name ||
                    '  SELECT sys_guid() FROM dual';
  EXECUTE IMMEDIATE 'SELECT id from ' || v_table_name
    INTO v_id;
  dbms_output.put_line(v_id);
  EXECUTE IMMEDIATE 'DROP TABLE ' || v_table_name;

END;
