      Description

      Found from logs in MCOL-676

      When executing a prepared statement that contains question marks but no params we crash in sql_parse.cc:9825:

      Item_param *param= *begin;
      

      Because "begin" is NULL.

      Example query:

      create table vstats_country (did INT, country CHAR(2), reqs INT, tx INT, tpr BIGINT, updatetime BIGINT) engine=columnstore;
       
      INSERT INTO vstats_country (did,country,reqs,tx,tpr,updatetime) VALUES (26818, '??', 2, 1713996, 1062, 1492917900)
