    Hi @sunjincheng121 . Thanks for the review.
    I already finished some changed for code cleaning and remove the duplicate 
test case base on your comment.
    
    There are some similar implements in other Database, 
    like MySQL, https://dev.mysql.com/doc/refman/5.7/en/bit-functions.html
    Oracle, https://docs.oracle.com/cd/E22583_01/DR/help/BitShift.html
    In Apache Spark, also exists similar implements, 
https://issues.apache.org/jira/browse/SPARK-8223
    
    Thanks,
    Du Bin
