  drop table if exists table_1;
  create table table_1(a clob )with (ORIENTATION=COLUMN);
  insert into table_1 values('1010'),('1001'),('1011'),('1111');
  select * from table_1;
  drop table if exists table_1;
  
  drop table if exists table_2;
  create table table_2(a blob )with (ORIENTATION=COLUMN);
  drop table if exists table_2;
