SAP HANA sql 导致系统主服务 index server宕掉的语句

今天在开发hana报表执行一条sql语句时hana突然宕机，经过反复测试终于找到原因：例如create column table test(
adatu date,)insert into test value ('20150128');select;map(adatu,0,'1','1m','2','2m') as monfrom (select;case when adatu > '20150111'then '1'else '2'end as adatufrom (select as adatu from test;))这个sql会引起hana index server 宕机，请大家分析分析，看看是不是hana 数据库的bug，还烦请有用Oracle的用户也试试，3Q。
