text: -- @testpoint: PLAN_TABLE进行insert操作，合理报错
  --建表
  drop table if exists explain_t23;
  create table explain_t23(a int, b int);
  --插入数据
  insert into explain_t23 values(generate_series(1,500),generate_series(500,1000));
  --使用EXPLAIN PLAN语句，返回EXPLAIN SUCCESS
  explain plan set statement_id='TPCH-Q4' for select count(*) from explain_t23;
  --查询PLAN_TABLE，标签信息也存储于PLAN_TABLE中
  SELECT statement_id,operation FROM PLAN_TABLE;
  --PLAN_TABLE使用insert语句，合理报错
  insert into PLAN_TABLE(statement_id,operation,projection) values('TPCH-Q5',MAX,a);
  --清理PLAN_TABLE表信息
  delete from PLAN_TABLE;
  --删表
  drop table explain_t23;
